Description

The group of inventions relates to woodworking, furniture and other industries and, in particular, to the manufacture of spring slats in the form of bent plywood battens, plates, etc. from formatted blanks, with side ribs processed for a given profile.

1.1. A known method of producing spring lamellas, including obtaining from a bent-glued sheet of a shield blank by four-sided trimming of a bent-glued sheet to dimensions in the form of a format blank, determining the length of the lamellas and their number, dissolving the format blank into spring lamellas while profiling their ribs. In this case, the positioning of the saw shafts, the axis of rotation of which are located in the horizontal plane, is carried out using an electronic digital position indicator, and the lateral adjustment of the lower shaft relative to the upper one with the tool installed on them is carried out using the rocker of the main bearing. See "PauL" brochure for Maschinenfabrik GmbH & Co. KG website: www.paul.eu. However, obtaining a format blank with four-sided trimming of a bent-glued board to fit the dimensions of the format blank requires two machines on the formatting line, while the second formatting line is extended. All this takes up large areas and has an additional set of sophisticated equipment.

1.2. A known method of manufacturing spring lamellas, adopted for the prototype, is the production of formatted blanks from a bent-glued shield by trimming the bent-glued shield to dimensions that determine the length of the lamellas and the dissolution of the formatted blank into spring lamellas, while profiling their ribs. In this case, the bending of a glued-glued board for dimensions is carried out simultaneously for two identical format blanks along three parallel straight generators, the distance between which determines the length of the lamellas. The release of such formatted blanks onto spring lamellas with simultaneous profiling of their ribs is carried out together with trimming to the size of the two extreme lamellas from the perimeter side with simultaneous profiling of their ribs using, for example, a K34G-OUR machine manufactured by PauL Maschinenfabrik GmbH & Co. KG. See the description of patent RU No. 2563674 publ. 09/20/2015. Although the dissolution with uncircumcised ends along the curve of the generator is possible, but subject to its readjustment.

2.1. A device is known for producing spring lamellas from a formatted workpiece using a multi-saw machine for producing strips from a formatted workpiece and a machine for double-sided face processing of strips to obtain a finished rounded profile of ribs, which consists of two devices. The first device consists of a bed, a mechanism for moving a preform, a block of saws with adjustable distance between them, the axis of rotation of which is located in a horizontal plane. The second device consists of a feed table with side stops, between which the strips are located, a movement mechanism and a two-spindle mechanism for processing the strips with mills of the corresponding profile. See brochure Javor stroji d.o.o. Pivka on the site: this method is implemented by a large number of sophisticated equipment and does not imply the receipt of lamellas of different formats at the same time. The use of two devices and single-sided double-sided face machining of the slats to obtain a finished rounded profile, in addition to the total metal consumption of this equipment, is unprofitable and irrational, leads to a significant increase in labor costs for their manufacture, use, maintenance and increase the cost of obtaining spring slats.

2.2. It is known that the device adopted for the prototype is a device for producing spring lamellas from a preform with simultaneous production of a finished rounded profile of ribs consisting of a closed case with side windows located at an angle above and side covers under them. The feed and movement mechanism based on the driveshaft for rotating and pressure guides in the form of rollers. The guides consist of twenty, arranged in two rows of ten rollers, between which the format blank moves. Two milling units spaced 525 mm apart with bearing bearings at the ends are mounted in different horizontal planes with the possibility of lateral adjustment of the lower milling unit using a hydraulic cylinder. This type of device “K34G-OUR” includes at least one insert table, and to feed into the device a formatted blank cut along the perimeter, you need to have a side table adjusted to the height of the first pair of rollers. See "PauL" brochure for Maschinenfabrik GmbH & Co. KG website: www.paul.eu. Compared with the analogue, this device allows you to get spring lamellas from the format blank with the simultaneous receipt of a finished rounded profile of the ribs. However, a format blank must be formatted on four sides along the perimeter, and if, for example, it is not formatted on two sides along a generatrix coinciding with a part of the circle, but formatted only on two sides along a generatrix that is a straight line that rotates in radius, then it cannot be chopped by this device. Simple maintenance is provided by expensive electronic-digital equipment with a control panel, and the lateral adjustment of the lower shaft of the milling unit relative to the upper is carried out using the rocker of the main bearing. It has dimensions in length and width respectively 2384 × 2240. This does not take into account the length of the attachment equipment in front of the device for feeding the formatted workpiece. The feed and moving mechanism on the basis of the driveshaft for feed rollers of twenty, arranged in two rows of ten rollers, between which the format blank moves, is complex and cumbersome. Using a hydraulic cylinder involves connecting the device to the hydraulic system.

3.1. A known mechanism for feeding and moving, consisting of a drive with a drive sprocket at the end of the protruding drive shaft. The drive sprocket is connected by a chain transmission to two driven sprockets located on one of the sides, two extreme clamping shafts. Each clamping shaft rotates in bearings mounted on top of both sides of the shaft on two parallel brackets. To tighten the chain, the preload sprocket on the preload lever is designed. Brackets are mounted on the lower rungs. All three drive shafts rotate along with three pairs of drive rollers located at the supports. Above three pairs of drive rollers are three pairs of pinch rollers. The pressure rollers themselves are mounted on two pairs on each side of the T-shaped levers, which are upright, and each crossbar of the T-shaped levers with their free ends is aligned with the axis of rotation of an adjacent pair of pressure rollers in the direction of movement of the bent-sheet material. The axis of the pinch rollers are located on top of the drive rollers on the same vertical line in the vertical plane of symmetry of the frame, forming a pair of movement during their rotation. Thus, when moving the bent-sheet material on the support rollers to the first front pair of movement, it simultaneously moves along three guides, two of which are located along two straight lines forming a cylindrical plane. In this case, the support rollers are similar to the driving rollers and rotate by moving the bent-sheet material along the outer diameter of its rim. See the description of patent RU No. 2563674 publ. 09/20/2015, FIG. 3 and 4. Although this mechanism for feeding and moving the formatted workpiece is simple and involves simple mechanisms for its implementation, it cannot be used for cutting along the curve generators used for cutting to obtain lamellas.

3.2. Known adopted for the prototype, the mechanism for feeding and moving the formatted workpiece, consisting of a gear motor, twenty rotating and pressure guides in the form of rollers located along a bend radius of 3-9 meters. Of these, ten are located on top of the curved side of the format blank, and the other ten on the bottom from the concave side of the format blank. At the same time, eight out of ten rollers of each row are arranged in pairs. Rollers are shafts with tips for installing them in bearing bearings on both sides. In this case, the feed rollers carry out rotation due to heavy-duty double chains with a tension system. Rollers located on top have the ability to move vertically. See "PauL" brochure for Maschinenfabrik GmbH & Co. KG website: www.paul.eu. Device type "K34G-OUR". This device is used to feed and move the formatted workpiece with cutting along the curve forming with obtaining lamellas. However, the feed and moving mechanism under consideration includes two rows of ten rollers, between which the formatted blank moves. Two milling blocks spaced by 525 mm significantly extend the path of movement of the formatted workpiece, which affects the overall dimensions of the device. Simple maintenance is provided by expensive electronic-digital equipment with a control panel.

4.1. A known system of pressing in the form of a clamping device to a woodworking machine, including a housing on which is mounted a rotating spring-loaded lever with a pressure roller. The stop is rigidly connected with the lever to the grooves into which the pusher enters with spherical washers, the pusher being moved by a handwheel mounted on the housing. See the description of the copyright certificate SU No. 1818220 with a priority of 04/01/91, publ. 05/30/93. Bull. No. 20. However, this clamping system has disadvantages, which include a change in the clamping forces from the thickness of the workpiece. In addition, the device is unreliable and complex in design, does not fully ensure safety during operation. It has a housing, due to which it cannot be used, for example, in an upright position.

4.2. Known adopted for the prototype, the clamping system, including a two-arm spring-loaded lever with the adjustment of its position in the form of a bolt and clamp, the axis of rotation of which is perpendicular to the lever, and the lever shoulders have different lengths and are located at an angle of 135 ° to each other and together they have a limiter rotation. The end of the short arm rests on a spring located perpendicular to the horizontal plane of its installation. The lever is mounted by hinging with the base in a horizontal plane. On the opposite side of the spring placement, the long part of the lever by a screw pair is connected to the screw support on the basis of the hinge joint. See the description of patent RU No. 20044419 publ. 12/15/93. This device is more reliable, has a simple design, but does not have a greater ability in the multidirectional adjustment system for all clamp coordinates and is only applicable for horizontal movement of the formatted workpiece.

5.1. Known milling unit, which consists of a set of removable double-cutter elementary milling cutters mounted on a hollow shaft located between the end driven shaft and the end drive shaft. The ends of the shaft are mounted in bearing bearings with two rolling bearings, one of which is the leading one and is connected to the drive through the coupling. See the description of the patent RU No. 2480328 with priority from 12.30.10 (see Fig. 9, 10). However, they can make a cut in the format blank if they are installed through the rollers in the form of bushings, the width of which will correspond to the width of the lamellas. But it does not provide lamellas with a rounded profile of ribs.

5.2. Known, adopted for the prototype, a milling unit consisting of a horizontally located hollow shaft, the ends of which are mounted in bearing bearings located on the side walls of the sliding part of the housing and rotating by means of a multi-way electrospindle. Milling discs with bushings between them are alternately mounted on the shaft. At the same time, the height of the saw shaft, and therefore the milling unit, is adjusted using a hydraulic cylinder. See "PauL" Maschinenfabrik GmbH & Co. KG website: www.paul.eu. Device type "K34G-OUR". Although they can produce cutting of a preform with obtaining lamellas of a finished rounded profile of ribs, Since the rotation axes of these two milling blocks are spaced apart by a distance equal to more than half a meter, the path of the passage of the formatted workpiece is lengthened by this distance and, accordingly, the milling and cutting time. And this leads to an increase in energy costs, metal consumption and overall dimensions of the device. In addition, this is why additional electronic equipment is required to match the installation of milling units.

6.1. Known milling disk in the form of two cutting elementary milling cutter, consisting of a sheet of tool steel with an axial Central hole and two protrusions of the cut, located around a circle through 180 in the form of two protrusions with pointed corners of the protrusions of the cut, facing the cutting side. See the description of the copyright certificate SU No. 1507566, published September 15, 89, bull. Number 34. The presence of a cutting part with an angular profile requires changing its shape, namely, making the straight lines of the angle of the cutting part concave in radius. But even if this refinement is carried out, there are still other significant shortcomings. For example, a rotation speed of three thousand revolutions per minute will significantly affect the imbalance if there are two holes in this structure located around the circumference in one quarter of its holes. Sharpening such a milling disc reduces the diameter of the cutting edges and additional adjustment of the system will be required after each sharpening. And the removal of the milling disc itself for sharpening involves the removal of the milling unit and its disassembly. All this complicates, lengthens the process of preparation and maintenance of the production process for the manufacture of slats and the cost of the process of their production.

6.2. Known adopted for the prototype, a milling disk, which is made of tool steel with an axial central hole and a plurality of cut protrusions, made at the same time with the cutting edge forming the cutting part. In this case, the cutting edges are evenly distributed around the circumference and are made with symmetrical radii of a quarter of a circle on the outside of the cutting edges to form a platform in the middle. Moreover, the disk on each side has two symmetrical parallel planes of different heights, and has a stepwise cross-sectional view, forming a two-sided thickening at the place of its nozzle on the shaft and a thickening of the protrusions of the cut, which is less than the thickening of the nozzle. See "PauL" Maschinenfabrik GmbH & Co. KG rice 5 on the website: www.paul.eu. Device type "K34G-OUR". It should be noted that, unlike the analogue, this design has cutting parts with a profile corresponding to the rounded profile of the lamella ribs and there are no direct unbalancing elements in its design. But the sharpening issue of such a milling disk has the same negative aspects, although the sharpening frequency, in the case of using carbide plates, is significantly reduced, but the sharpening itself is complicated. Additional adjustment of the system after each sharpening, removal of the milling disk for sharpening involves the removal of the milling unit and its disassembly complicates, lengthens the process of preparation and maintenance of the production process for the manufacture of slats and the cost of the process of their production. In this case, complicates the design of the device for the manufacture of slats.

7.1. A known method of moving a formatted workpiece when the formatted workpiece is located on a concave surface on three straight guides that coincide with the straight lines forming this surface and located at an angle along the radius of the concave surface and moves along them under the action of an external force until it enters between two pairs of rollers. See the description of patent RU No. 2563674 publ. 09/20/2015. Although this method of moving a formatted workpiece is simple and involves simple mechanisms for its implementation, however, it cannot be used for cutting along curved generators, along which milling and cutting of a formatted workpiece into lamellas takes place.

7.2. Known, adopted as a prototype, is a method of moving a formatted workpiece when feeding is carried out by moving it horizontally with a concave surface between the rotating and pressure guides in the form of rollers, the axis of rotation of which are parallel to the straight lines forming this surface. Moreover, these axes of rotation of the lower rollers along the path of movement of the formatted workpiece are distributed along the radius of its concave surface, and the formatted workpiece is preliminarily located by the supplying front end at the height of the feed clearance, the width of which is from 800 to 1200 mm. After the front part is installed on the first rotating roller due to external forces, the formatted workpiece is advanced until it hits the second and third rotating lower rollers, after which the first three upper rollers are lowered and the formatted workpiece moves further at a speed specified by the movement mechanism and enters the cutting zone of the first milling unit. When passing through the first milling unit, the curved surface is processed to half the thickness of the preform with the counter direction of rotation of the milling unit. Next, the formatted workpiece moves to the second milling unit along the four lower rollers and three lowering upper rollers, falling on the insert table, where it is processed from the concave surface to the second half of its thickness with the opposite direction of rotation of the milling block. Next, the finished lamellas are moved outside the device with the help of three lower rotating rollers and four pressure upper rollers. See "PauL" brochure for Maschinenfabrik GmbH & Co. KG website: www.paul.eu. Device type "K34G-OUR". This method of moving the formatted workpiece can be used for cutting along the curved generatrices along which there is a cutting to obtain lamellas. However, the implementation of this method is provided by a complex system for its regulation and requires complex and bulky equipment. Moving the formatted workpiece from one milling unit to the second milling unit is lengthy and increases the idle speed of its movement, and the lifting and clamping system of the upper rollers requires additional energy costs.

8.1. A known method of processing wood billets by milling, in which the workpiece moves, and the cutting tool, rotating, stands in one place. In this case, the tangent of the rotation vector of the cutting tool at the time of the beginning of the cut is opposite to the direction of motion of the workpiece, and at the end of the cut, the tangent of the rotation vector of the cutting tool is at an acute angle in the direction of motion of the workpiece. See Encyclopedic Handbook. Engineering. Section Four, “Designing Machines,” Volume 9, M, GNSTI, Engineering Literature, 1949, p. 679, FIG. 10. In this case, during the cutting process, the chips fall on the surface of the incoming workpiece in front of the cutting tool and a device is needed to remove the chips from the surface to be treated so that it does not interfere with the processing of the part. As a rule, these are powerful suction devices. This process of processing wood billets is applicable only to obtain smooth surfaces located in a horizontal plane and cannot be used to dissolve the billets into separate parts.

8.2. Known for the prototype, the method of milling and cutting, in which two-sided milling of a moving formatted workpiece is performed, and a cutting tool in the form of two milling disks spaced apart along the radius of the formatted workpiece by an angle of more than 30 ° and, rotating in the direction of the feed direction, stand on one place. In this case, first a cut is made from the side of the curved surface to half its thickness, and then from the side of the concave surface to the second half. The axis of rotation of the milling discs are parallel to the horizontal plane and the direct generatrices of the concave and curved surface of the blank. See "PauL" brochure for Maschinenfabrik GmbH & Co. KG website: www.paul.eu. Device type "K34G-OUR". This method allows milling to produce cutting of blanks into separate lamellas with obtaining ribs of a certain shape. However, the implementation of this method is provided by a complex system for its regulation and requires complex and bulky equipment. The initial cutting of a preform on a convex surface and the final cutting from the concave surface increases the milling and cutting process, and requires additional energy costs for its implementation.

The task of the group of inventions is to teach a less complex, cumbersome and costly process of manufacturing slats.

The technical result of the group of inventions is to increase the reliability of the device, which ultimately affects the reduction in the cost of obtaining the final product. Reduce the intensity of the devices used. Simplify maintenance. Reduce the number of preparatory operations in the manufacture of slats. Increase compactness.

Moreover, the two-shoulder spring-loaded lever has shoulders located at an angle of 90 ° and at the end of the long shoulder there is a spring working in tension and the second end of which is connected to a finger mounted on a table with emphasis on a vertical rack with the possibility of its limited rotation in a plane parallel to the plane of the table around the vertical mounting axis of rotation, while on the free end of the short arm through the corner section there is a removable bracket consisting of two strips, one of which is parallel about the plane of the table, and the second perpendicular to the plane of the table, on the free ends of which are made bearings with bearings located in them, while the axis of rotation of the bearing located on the first bar coincides with the axis of the vertical mounting axis of rotation and is vertical to the plane of the table, and the axis of rotation the bearing located on the second bar is parallel to the plane of the table and is directed perpendicular to the direction of movement of the blank on which the bearing bracket is located of the clamp in the form of a corner with shelves of different lengths and thicknesses, the free end of the long shelf being a support for holding the clamp bearing in it, the axis of rotation of which is 10 degrees deviated from the vertical in the direction of movement of the blank, and a plate is attached to the short shelf from below passes under the bar, parallel to the plane of the table with an exit beyond its dimensions and the end of which is connected to the spring, and the free end of the spring is attached to the upper part of the bent J-shaped plate, which is mounted on top of this bar.

This goal is achieved in that the milling unit, including the bearing support, a shaft with alternately mounted milling disks and bushings between them, has a shaft that is made with a protrusion abutting against the end face of the lower inner ring of the bearing located below in the bearing assembly, the flange of which is designed for installing the shaft in a vertical position on the table surface and the possibility of its movement, and milling discs and pressure guides, in the form of a set of pressure rollers with bearings in the center the holes are mounted on the shaft between the cylindrical spacers with their emphasis on the ends of the inner ring of these bearings and milling discs on both sides, and the milling disc mounted below, with the lower cylindrical bore, rests against the top of the end face of the inner ring of the upper bearing located above in the bearing assembly due to tightening the nut on the shaft end protruding from the upper cylindrical spacer.

In this case, the cutting insert with a cutting edge is removable, and the disk is made flat with an axial central hole for the milling unit shaft and with parallel sides defining the thickness of the disk and the width of the cutting insert, the cutting edge of which is made with symmetrical radii of a quarter of a circle along the width of the cutting edges , forms a platform in the form of a rounded protrusion, while the end face of the disk is made in the form of a similar cutting edge with closed radii along the outer diameter of the disk, while the circumference of the outer diameter d it is smaller than the diameter of the circle of rotation of the cutting edge of the cutting inserts, the disk is made with six cutting protrusions located 60 ° around the circumference and has six supporting protrusions, respectively, with a cutting plate located on each cutting protrusion, which presses the cutting insert against the supporting plate by the screw of the supporting protrusion the protrusion of the cut through the spacer.

In this case, the feeding of the formatted workpiece is carried out by pressing it over the flat guide with a force of the curved surface to the two plates of vertical guides, pre-configured tangentially to a radius equal to R + S, while two machined ends of the formatted workpiece are installed vertically relative to the flat guide, and the curves bent along the radius and forming the same surface by vertical movement, are parallel to the flat guide and are between two untreated ends, the installation and clamping of the formatted workpiece is carried out with its simultaneous movement between the two vertical guides of the flat plates and the outer diameter of the clamp bearing of the clamping system, located on the side of its concave surface until the vertical end contacts the first vertical rotating guide, while the outer diameter of the clamp bearing RSP implements its pressing against two vertical guides, and further movement of the format blank with a constant speed, we set The motor-reducer of the movement mechanism between the rotating and clamping rails is made in an alternating sequence of contact between the curved and concave surfaces of the formatted workpiece along its path with four vertical rotating guides and two clamping rails in the form of a set of clamping rollers of two milling blocks located along its path, starting from the contact of the curved surface of the preform with the first vertical rotating guide: where

For convenience of presentation, it is advisable to start an example of a concrete implementation by setting out a device for producing spring lamellas from a formatted workpiece while simultaneously producing a finished rounded profile of the ribs, which consists of a feeding and moving mechanism, table 1, on which two milling blocks are located vertically to it. 2 and 3 with two brakes 4 and 5. In front of the milling blocks 2 and 3, on one side there is a flat guide 6, next to which two vertical guides 7 are installed on one side along it, 8, and one vertical rotating guide 9, and on the other opposite side of the flat guide 6, a clamping system 10.

Behind the milling blocks 2 and 3, on the table 1 there are three more vertical rotating guides 11, 12 and 13.

At the bottom of table 1 are two actuators 14 and 15 (see Fig. 2) for milling units 2 and 3, respectively, and a gear motor 16 of the feed and displacement mechanism, as well as a tension system 17 of chain 18 and two adjusting levers 19 of rotation drives 14 and 15 milling blocks 2 and 3.

Table 1 is a rectangular flat plate, bottom closed around the perimeter of the box 20 (see Fig. 3).

Each milling unit 2 and 3 consists of a shaft 21 with a protrusion 22 along the outer diameter (see Fig. 3, 4), which is inserted from below into the bearing support 23 mounted on the table 1 until the protrusion 22 stops from below on the inner ring of the lower bearing 24. On the protruding, on top of the bearing support 23, end of the shaft 21, hollow cylindrical spacers 25, milling discs 26 and pressure rollers 27 are sequentially mounted. On top of the shaft 21 of the milling unit assembly is a nut 28, which, through the upper spacer 25, carries out the lower spacer 25 to inner ring tsu of the upper bearing 29 from above.

The pressure roller 27 is made in the form of a flat lightweight disc with a cylindrical outer pressure surface 30 (see Fig. 4) and a hole inside. A bearing 31 is installed in the bore of the hole of the pinch roller 27, the inner diameter of which corresponds to the outer diameter of the shaft 21.

The flat guide 6 (see Fig. 1) is made in the form of a triangular plate with a figured protrusion at the apex of an acute angle and is parallel to the plane of table 1 along its long side with a short side at the edge of table 1 from the side of the feed of the format blank 32 (see Fig. 5, 10). In this case, the curved protrusion of the acute angle of the flat guide 6 (see Fig. 1) is installed in the region of receipt of the format blank 32 at the two milling units 2 and 3 and is directed towards the milling unit 2.

The feeding and moving mechanism includes two vertical guides 7 and 8, (see Fig. 1) a clamping system 10, four vertical rotating guides 9, 11, 12 and 13, pinch rollers 27 (see Fig. 4) milling blocks 2 and 3 , the gear motor 16 (see Fig. 2) of the feeding and moving mechanism with a chain 18 and a system of its tension 17. In this case, the vertical rotating guide 9 together with the clamping system 10 are installed in front of the cutting zone and carry out the initial capture and feeding of the blank 32 (see Fig. 5), moving it at a certain speed cutting zone and passing it between two milling units 2 and 3 for receiving several lamellas of the finished profile.

The two vertical guides 7, 8 have the same design and consist of a plate 33 (see Fig. 5) connected by an integral connection to the protruding end of the stud 34 above the surface of the flat guide 6, the bottom of which is 1. At the same time, the vertical guide 8 is installed as close as possible to the vertical rotating guide 9 so that when installing and moving the formatted blank 32, it is guaranteed to rest with its curved side on the vertical rotating guide 9, and not hit the concave side thereof.

These two vertical guides 7, 8 are flags allowing, depending on the insertion angle of the plates 33 and the parameters of the format blank 32, to help direct it to the capture zone and capture it and move with a certain identity and then direct it to the cutting zone between the milling units 2 and 3.

The clamping system 10 consists of a L-shaped lever 36, the shoulders of which have different lengths (see Fig. 6) and are located at an angle of 90 °. The L-shaped lever is located parallel to the plane of the table 1 on the vertical installation axis of rotation 37 (see Fig. 5, 6) with emphasis on the vertical rack 38 and the possibility of its limited rotation in the horizontal plane around the vertical installation axis of rotation 37 mounted on the table 1.

The long shoulder of the L-shaped two-shouldered lever 36 is located in the direction of movement of the blank 32, and its free end is connected to the spring 39. The second end of the spring 39 is connected to the pin 40, which is a stud mounted vertically on the table 1 and is attached to it with two nuts 41. The short arm of the L-shaped lever 36 is located on the previous in the direction perpendicular to the movement of the format blank 32. On one side on the outside of this component of the L-shaped lever 36 is installed an adjustable stop 42, restrictions the rotation of the L-shaped lever 36 in a horizontal plane around the vertical mounting axis of rotation 37. At the other - free end of the L-shaped lever 36 is located by means of a one-piece connection a piece of corner 43 on which the bracket 44 is mounted.

The bracket 44 has two slats 45 and 46, on the free ends of which are made supports with bearings 47 and 48 located in them, respectively. In this case, the axis of rotation of the bearing 47 coincides with the axis of the vertical mounting axis of rotation 37 and are located vertically to the plane of the table 1, and the axis of rotation of the bearing 48 is parallel to the plane of the table 1 and directed perpendicular to the direction of motion of the blank 32.

The axis of rotation of the bearing 48 coincides with the mounting axis 49, on which the bearing 48 is mounted with an emphasis on the sleeve 50, made in the form of a removable ring on the outer diameter of the mounting axis 49.

On the mounting axis 49 is located the bracket 51 of the bearing 52 in the form of a corner with shelves of different lengths and thicknesses. The free end of the long shelf of the bracket 51 is a support for the location of the clip bearing 52 of the format blank 32 to the plate 33 of the vertical guide 7. In this case, the axis of rotation of the bearing 52 of the clip 52 is deviated from the vertical by 10 degrees in the direction of movement of the format blank 32. From the bottom to the short shelf in in the form of a protrusion 53 of the bracket 51 is attached (the fastening is not shown in FIG.) a plate 54, which extends below the bar 45 beyond its dimensions and whose end is connected to the spring 55. The free end of the spring 55 is attached to the upper part ti bent L-shaped plate 56 which is mounted on top of the bar 45.

The bracket 44 is assembled through a section of the corner 43 of the L-shaped lever 36 is attached to it using a bolt 57.

Four vertical rotating guides 9, 11, 12 and 13 of the feeding and moving mechanism have the same design and consist of (see Fig. 7) a stepped shaft 58 with a protrusion 59 on the outer diameter and blind holes along the axis of rotation from its two sides. A roller 60 is mounted on top of the shaft 58 with a support on the protrusion 59, and is pressed against it with the pressure washer 61 and the bolt 62. The shaft 58 is stepped on the bottom of the protrusion 59. The shaft 58 is mounted vertically on top of the bearing support 63, located on the table 1 and from below on its free end through a system of removable compression bushings 64 and washers, a driven sprocket 65 is mounted, which is mounted on the shaft 58 with an emphasis on the upper movable sleeve 64 similar to roller 60.

Bearing support 63 is a prefabricated and similar to bearing support 23 and is a rectangular flange 66 with a through hole in the Central part. Moreover, this hole in diameter is slightly smaller than the outer diameter of the outer ring of the bearing 67 enclosed in a cage 68 and smaller than the diameter of the hole in the table 1 for the installation of a rectangular flange 66 with a through hole in the central part. Moreover, the rectangular flange 66 is the basis for the installation of vertical rotating rails 9, 11, 12 and 13 assembled on the table 1. At least two bearings 67 are installed in the cage 68

The upper annular flange 69 with holes around the circumference and bolts 70 passing through the through holes of the cage 68 create a single design of the bearing support 63 and vertical rotary rails 9, 11, 12 and 13 on the corresponding rectangular flanges 66. Vertical rotary rails 9, 11, 12 and 13 assembled mounted on the table 1 in the direction of movement of the blank 32 and bolted to it 71 through holes in the form of a groove in the corners of the rectangular flanges 66 (see Fig. 1).

Although the bearing bracket 63 is similar to the bearing bracket 23, they differ in the way they install their shafts and the way they are mounted in the bearings. So the shaft 58 in the bearing support 63 is mounted on top and mounted on the bottom, and the shaft 21 in the bearing support 23 is mounted on the bottom and mounted on top.

The gear motor 16 of the feeding and moving mechanism (see Fig. 8) with a drive sprocket 72 on the protruding end of the gear shaft 73, a chain 18 (see Fig. 2) and its tension system 17 are located below the table 1 inside the box 20 (see Fig. 8), thereby protecting service personnel from accidentally falling into their area of operation.

The drive sprocket 72 (see Fig. 2) and the driven sprockets 65 are in the same plane parallel to the plane of the table 1 and are connected by a chain 18 in such a way as to provide the rotation of the driven sprockets 65 of the vertical rotating guides 9 and 12 clockwise, and the rotation of the driven sprockets 65 vertical rotating rails 13 and 11 counterclockwise.

The tension system 17 of the chain 18 is a two-arm lever, bent in the middle at an angle of 120 °. In the corner part there is an opening for its installation by means of a swivel joint with the bracket 74. The swivel joint allows limited rotation of the two shoulders of the lever in a plane parallel to the plane of the table 1. The bracket 74 is mounted inside the box 20 on its front wall. A tension sprocket is installed on one end of the lever of the tension system 17 (the position is not indicated by a position), and on the second end of the lever is a spring 75 and turnbuckle 76 with the latter installed and fastened on the opposite wall of the box 20. The second end of the lever of the tension system 17 is from the front of the box 20 equipped with an adjustable stopper 77 made in the form of a bolt mounted on this wall.

Two mounting levers 19 of the actuators 14 and 15 consist of pipe sections of rectangular cross-section. On one free end of each mounting lever 19, angles 78 and 79, respectively, are installed (see Figs. 2, 3), the long shelves of which are facing each other, and the short shelves are facing in different directions. The long flanges of the corners are connected to the actuators 14 and 15 by bolted connections 80 and 81 (see Fig. 2), and the short flanges of the corners with pipe sections of the mounting levers 19 are bolted 82. The free ends of the mounting levers 19 are connected to the brackets 83 mounted on the rear wall inside the box 20 by means of a swivel joint 84. With this wiring diagram, the energy of the drives is directly transmitted to the shaft of the working body, while the moments of rotation that occur during the start-up and operation of the drives are compensated by levers 19 for compensating these moments.

A vertical rotating guide 9, together with a clamping system 10, is installed in front of the cutting zone and initially grabs and feeds the blank 32, moving it at a certain speed to the cutting zone and then between two milling units 2 and 3 to obtain a given number of finished profile slats. Thus, the cutting zone is determined by the portion of the path passing the formatted workpiece from capturing its vertical rotating guide 9 to capturing its vertical rotating guide 11.

Vertical rotating guides 11, 12 and 13 are installed after passing the format blank 32 of two milling units 2 and 3, carry out the initial capture and movement with the removal of the finished profile of the lamellas from the cutting zone.

The milling disk 26 is made lightweight, with six protrusions of the cut 85 (see Fig. 9) located 60 ° around the circumference and respectively have six support protrusions 86. On each protrusion of the cut 85 there is a cutting insert 87 with a cutting edge, which is screw 88 through the spacer 89 presses the cutting insert 87 against the bearing pad of the protrusion of the cut 85.

A method of moving a formatted blank 32 (see Fig. 5 and Fig. 10) involves installing a formatted blank 32 by pressing its curved surface to the vertical plane of the plates 33 of the vertical guides 7 and 8, pre-configured tangentially to the radius R + S. Where R is the internal bending radius of the format blank in mm and characterizes its concave surface. S is the thickness of the format blank in mm. The clamp is carried out due to the external clamp force P _wu (see Fig. 10). Where R _wu is the external clamping force of the blank 32 to the plane of two plates 33 of the guides 7 and 8, in kgf.

In this case, two machined ends of the format blank 32 for the length of the lamellas after cutting a sheet of bent plywood on a format-cutting machine are installed vertically relative to a flat guide 6 above its surface. In this case, the curves bent along the radius and forming the same surface by vertical movement are parallel to the flat guide 6 and are located between two raw ends of the format blank 32.

The plates 33 of the vertical guides 7, 8 are arranged vertically tangentially to the curves bent along the radius R + S and form this curved surface by vertical movement. These two tangents will be straight vertical and parallel lines, by definition, with a distributed clamping force P _wu , and are the supporting components for moving the blank 32 along all the paths of its movement. This arrangement is similar to the location of a large diameter pipe on top of two parallel guides, the distance between which is equal to half the radius or less. This pipe, under its own weight, will itself occupy an arrangement in which the axis of rotation of the pipe passing along its length occupies a position parallel to the two parallel guides on which it is laid. In this case, the weight of the pipe is equivalent to the external clamping force P _wu . Now, if inside the pipe, place the guide between two parallel guides located below and parallel to them, then the pipe will take a stable position, and it can be moved. Now, if you cut off the upper part of the pipe and arrange the remaining part vertically with a secant horizontal plane passing above two parallel guides and below the axis of rotation of the pipe, then we get our option to install the format blank 32. In this case, if you don’t apply any efforts, the rest of the pipe will be under its own weight, go down to any stop, and the surface itself will not be able to deviate to the left or right of the vertically located three guides.

In our case, when installing the format blank 32, the same principle of installing part of the pipe is used, while the guides are tangent straight vertical lines, called the supporting components of the movement of the format blank 32.

Installation and clamping of the blank 32 is carried out with its simultaneous movement until the vertical end contacts the first vertical rotating guide 9. When installing and moving the blank 32, it passes through two preparation zones for grabbing. Each zone includes three elements of exposure. In the first, these are vertical lines of contact along a tangent to a curved surface with a preform 32 and the plane of two plates 33 of guides 7 and 8, as well as the external pressing force P _w .

The second grip preparation zone includes the external clamping force P _sp and the outer diameter of the clamp bearing 52 of the clamping system 10 creating contact with the concave surface of the format blank 32, as well as the plane of the plate 33 of the guide 8, which acts tangentially to the curved surface of the format blank 32. Where R _sp - clamping force with a preform 32 of the clamping bearing 52 to the supporting components in kgf. Here, the supporting components of the movement of the format blank 32 are the planes of the plates 33 of the guides 7 and 8 and the touching of the end face of its first vertical rotating guide 9, tangential to the curved surface of the format blank 32. The plate 33 of the rail 8 prevents the concave surface of the format blank 32 from falling onto the vertical rotating guide 9.

Under these conditions of arrangement and movement of the format blank 32, it has only two degrees of free movement. This is towards its processing and vertically down to the very first from the bottom of the protrusion of the raw side. Thus, the conditions for the stable movement of the workpiece are created, in which two machined ends move vertically relative to the flat guide 6. Moreover, in this section, the movement of the format blank 32 to the first vertical rotating guide 9 can be either accelerated or slowed down.

Then, the first vertical end face of the blank 32 is in contact with the roller 60 of the vertical rotating guide 9, and when the blank is 32 further moved beyond the contact of its curved surface with the straight line forming the outer surface of the roller 60, the blank is moved 32 at a constant speed specified by the movement mechanism.

Thus, outside the capture zone, the preform 32 enters the cut zone and its movement before the cut and during the cut is characterized by a constant speed and a stable position. This stable position with a constant speed of movement is characterized in that the two supporting components in the form of vertical lines are located on the outer side or the curved side, and the third component is on the inner side or the concave side between the two first supporting components and spaced along the radius R of the blank 32. Such groups of three components are located along the entire path of movement of the format blank 32.

So in the area of movement of the end face of the preform 32 from the gripping zone to the beginning of the cut, two supporting components in the form of two vertical straight lines are located on the curved side, formed from the contact of the plane of the plate 33 of the guide 7 and the cylindrical surface of the roller 60 of the vertical rotating guide 9. The third supporting component in the form the outer diameter of the clamp bearing 52 of the clamping system 10 is located on the concave side of the format blank 32 and is located between the first two.

Next, the process of cutting the format blank 32 into several spring slats. Moreover, the notched format blank 32 has two supporting components in the form of two vertical straight lines located on the curved side, formed from the contact of the plane of the cylindrical surface of the roller 60 with a vertical rotating guide 9 and the outer cylindrical surface 30 of the pressure roller 27 of the milling unit 3. The third supporting component in the form the outer cylindrical surface 30 of the pressure roller 27 of the milling unit 2 is located on the concave side of the format blank 32 and is located between the first two . In this case, the vertical lines from the outer cylindrical surface 30 of the pressure rollers 27 of the milling units 2 and 3 are discrete lines.

The following three supporting components are formed by the outer cylindrical surface 30 of the pressure roller 27 of the milling unit 3, the cylindrical surface of the roller 60 of the vertical rotating guide 12 and the cylindrical surface 30 of the roller 60 of the vertical rotating guide 11. The latter is located on the concave side of the blank 32, and the first two are located on the curved side of the lamella-shaped blank 32.

The last three supporting components are formed by the cylindrical surface of the roller 60 of the vertical rotating guide 11, the cylindrical surface of the roller 60 of the vertical rotating guide 13 and the cylindrical surface of the roller 60 of the vertical rotating guide 12. The vertical rotating guide 12 is located on the curved side of the blank 32, and the vertical rotating guides 11 and 13 are located on the concave side, cut into slats of the format blank 32.

Such three supporting components provide a stable predetermined location of the format blank 32 along the entire path until it reaches the lamellas and goes beyond the limits of the milling blocks.

In this case, the rotation of the milling discs 26 and the pressure rollers 27 facilitates the movement of the format blank 32, in the direction of its movement, provides a stable process of cutting the format blank 32 into individual lamellas, regardless of their length, to obtain edges of a given shape.

The method of milling and cutting, in which the workpiece, namely, the preform 32 moves between two milling disks 21 located in the same plane. In this case, the cutting tool in the form of two milling disks 21, assembled in the form of two milling blocks 2 and 3, rotate, stand vertically in one place relative to the flat guide 6, and the format blank moves between the pressure rollers 27 of the two milling blocks 2 and 3, the milling disks 26 which are distributed vertically and each pair of them is in a plane parallel to the plane of table 1. At the same time, the milling discs 26 rotate in the direction of movement of the format blank 32, and the axis of their rotation in a plane parallel to the plane of table 1 is offset from ositelno each other at an angle γ towards the moving format workpiece 32. Such rotation of milling disks 26 and movement of the workpiece 32 corresponds to the format climb milling and accompany cutting process.

The depth of cut on a concave surface exceeds the depth of cut on a curved surface: where γ is the angle of displacement of the axis of rotation of a pair of milling discs of two milling blocks located in one plane parallel to the plane of the table in degrees.

A method of producing spring slats from a formatted blank while simultaneously producing a finished rounded profile of the ribs includes installing the formatted blank 32 vertically above a flat guide 6 with pressing its vertical generators with a curved surface against two spaced apart vertical planes of two plates 33 of vertical guides 7, 8 pre-set to a radius R + S and moving it in this position towards the milling blocks 2 and 3 to the first vertically rotating guide 9 and pressing it with Rhone concave surface 52 urging the pinch roller 10 to the plate 33 of the system the vertical guide 7 and 8. In this case, sizing the preform 32 can only descend vertically until the first touch maximize its protruding bottom edges with the top flat guide plane 6.

Further movement of the formatted blank 32 is carried out by a moving and feeding mechanism at a constant speed towards two milling units 2 and 3 and then between a set of a pair of milling discs 21, vertically distributed in one plane parallel to the plane of table 1 with a certain step corresponding to the width of the lamella. Passing it between two milling blocks 2 and 3, providing passing milling and cutting it to obtain a finished rounded profile of the ribs along the entire length of the format blank 32.

A device for producing spring lamellas from a preform with the simultaneous production of a finished rounded profile of the ends is made of separate assembly units and parts made mainly of sheet and section steel of art. 3, 20 and 45.

So table 1 is made of sheet steel, article 20, in the form of a rectangular sheet with a thickness of 25.0 mm and a size of 630 × 1600 mm, from the bottom of which a box 20 is attached to it along the perimeter, made of sheet steel with a thickness of 5.0 mm and with flanges.

The flat guide 6 is made of st. 45 sheet steel and in finished form has a thickness of 23 mm, and the height of its triangular shape together with the protrusion is 925 mm and with a base length of 240 mm.

The figured protrusion at the apex of the corner has a width of 60 mm with a bevel on a length of 75 mm and a notch with a radius of 33 mm on its other side, the center of the radius of which is 850 mm from the base. To install a flat guide 6, it has three protrusions with through holes, two of which are made at the base and one in front of the figured protrusion from the recess. The flat guide 6 with the upper plane is located above the table 1 at a height that is lower than the lower plane of the lower milling discs 26. This height is adjusted depending on the unevenness of the resulting format blanks 32 that do not have trim.

On the table 1 and in the box 20 after marking, through holes are made, including threaded ones, for the installation of the corresponding assembly units and individual parts.

The marking on table 1 is as follows. On the upper front side of a rectangular table located in a horizontal plane, a bend projection of a formatted workpiece is applied in the form of an arc with a radius of R = 2950 mm, which is the internal bend radius of the formatted workpiece. Then the bend projection of the formatted workpiece in the form of an arc is applied, in our case, with a radius of R + S = 2950 + 8 = 2958 mm, which is the external bend radius of the formatted workpiece. The projection of the bending of the formatted workpiece in the form of an arc is applied so that the axis of rotation of the shaft 21 of the milling unit 2 and, accordingly, the axis of rotation of the pressure roller 27 is below the table 1 at a height equal to 230 mm and is 610 mm from the left edge. The projection of the pinch roller 27 in the form of a circle touches the inner radius R of the bend of the blank 32. Then, through the axis of rotation of the shaft 21 of the milling unit 2, an oblique line is drawn at an angle γ = 10 ° at an angle to the vertical and the tangent projection of the outer surface 30 of the pinch roller 27 in the form of a circle with an external bend radius R + S of the format blank 32, the axis of rotation of the shaft 21 of the milling unit 3 is determined.

Further, the marking on the table 1 is made from the marking of the axes of rotation of the shafts 21 of the milling blocks 2 and 3 and the bending projections of the format blank 32. So for installing vertical rotating guides 9, 11, 12 and 13 and determining the coordinates of the holes for their installation proceed from the same principle of contact projections of the bend of the format blank 32 and the projection of the circumference of the roller 60. Through these coordinates on the table 1 drill through holes with a diameter of Φ = 62.0 mm for their installation. The flat guide 6 is set so that the vertical axis of the hole for the installation of the vertical rotating guide 9 coincides with the vertical axis of the recess with a radius of 33 mm of the curved protrusion of the flat guide 6. The flat guide 6 is located on the top plane above the table 1 at a height of 110 mm with three studs 90 ( see Fig. 5) and nine nuts M12 × 1.25. Nuts with studs 90 are installed so that they do not protrude beyond the upper horizontal plane of table 1. Similar holes of different diameters are cut to install milling units 2 and 3, vertical guides 7, 8, vertical mounting axis 37, etc.

The manufacture and assembly of milling blocks includes the manufacture of a shaft 21 (see Fig. 3) from st.45 round rolled products (round timber) with a length of 670 mm on which, on the one hand, the first groove is made for a diameter of F = 40 mm and a length of 550 mm to the protrusion 22. The second groove is made at a diameter of Ф = 36 mm, length 50 mm, on which a M36 × 1.5 thread is cut under the nut 28. On the other hand, the shaft 21 is grooved for mounting drives 14 and 15 to a diameter of Ф = 28 mm, 100 mm long before the formation of the protrusion 22. In our case, the protrusion 22 is obtained with a length of 20 mm and an external diameter of Φ = 50 mm. The ending of the shaft 21 at a diameter of F = 28 mm has a corresponding revision for connecting the shaft to the corresponding coupling (not indicated by a separate number in the figures) mounted on the protruding end of the drives 14 and 15. Couplings for connecting these shafts 21 and the protruding ends of the drives can be made, for example, according to the invention, protected by patent RU No. 2477396 with a priority of 12.30.2010.

The pressure rollers 27 (see Fig. 4) are made of a flat round billet with a groove along the outer diameter to obtain a cylindrical outer pressure surface 30 with a diameter of Ф = 184 mm and a height of 25 mm in the center of which a through hole is drilled with a diameter of = 184 mm Ф = 60 mm, which is then drilled for mounting a bearing 31 with a diameter of Ф = 68 mm and a depth of 20 mm with a recess in diameter Ф = 68 mm for installing a snap ring С68 GOST 13943-86. From the spirit of the sides at the end there are facilitating grooves.

As a specific bearing 31, bearing No. 80108 manufactured in accordance with GOST 7242-81 was selected.

The bearing 31 is inserted into the hole with a diameter of F = 68 mm to the stop and is fixed there from displacement along the axial line of the retaining ring. Pinch roller 27 is ready to install.

Milling disk 26 is made of a sheet of tool steel with a thickness of 10 mm and a diameter of Ф = 190 mm with an axial central hole with a diameter of Ф = 40 mm as follows. According to the outer diameter Φ = 190 mm, symmetrical grooves are made with a cutter with a rounded radius of 10 mm on both sides to a depth of 5 mm with the formation of a 1.0 mm wide protrusion in the center. Thus, the width of the outer diameter f = 190 mm is equal to one millimeter.

Six holes with a diameter of F = 32 mm are drilled around a circle with a diameter of Φ = 98 mm, thereby facilitating the weight of the milling disc. Then, on three axes passing through a central hole with a diameter of Ф = 40 mm and two opposite holes with a diameter of Ф = 32 mm, six holes with a diameter of Ф = 12 mm are drilled around a circle with a diameter of Ф = 156 mm. Then, when these three axes are rotated around the axis of the central hole with a diameter of Ф = 40 mm by an angle of 6 ° against rotation of the cut around a circle with a diameter of Ф = 160 mm, six more holes with a diameter of Ф = 12 mm are drilled. Then, parallel to three axes passing through a central hole with a diameter of Ф = 40 mm and two opposite holes with a diameter of Ф = 32 mm, six holes are made in the form of an oval groove 12 mm wide and 24 mm long along the axis along the long side of the groove. The distance between these axes in the projection on the horizontal plane of the installation of the milling disk is equal to 35 mm In this case, the groove on the axis passing along the long side of the groove is separated from the point of contact of this axis with a diameter of Ф = 190 mm of the milling disk by a size equal to 16 mm.

It turned out a disk with an external A-shaped profile at the end, a central hole in the center and six facilitating holes with a diameter of Ф = 32 mm distributed symmetrically around a circle through 60 ° and having three axial lines, respectively, passing through two opposite holes and the center of the central hole. In addition to these holes, there are three more groups of through holes distributed around the circumference through 60 °.

This is: the first group of six holes with a diameter of F = 12 mm, which are involved in the manufacture of the platform of the support protrusion 86 from the installation side of the screw 88 and the back side of the six protrusions of the cut 85;

the second group of six holes with a diameter of F = 12 mm, which are involved in the manufacture of six support protrusions 86 from the outlet side of the screw 88 and the beginning of the six protrusions of the cut 85 from the cut side and on which the cutting inserts are located;

a third group of six grooved holes will participate in the manufacture of six protrusions of the cut 85 from the side of the cut.

Then, a cutting pad of the protrusion of the cut 85 is formed with a cutting wheel or laser, positioning the cutting wheel vertically and parallel to a vertical plane, in which there is an axis passing through the center of the central hole and the axis of two opposite holes, with the horizontal position of the milling disk blank. In this case, the first cut line of the cutting wheel should coincide with the plane of the near side of the hole in the form of a groove. A second cut line is made along an axis running along the long side of the groove. The second cutting line may extend further than this axis, but it should not extend to the far long side of the hole in the form of a groove. This operation to form the supporting platform of the protrusion of the cut 85 is repeated five more times with the workpiece turning 60 ° around the central axis of the central hole.

Then, a pad of the support protrusion 86 is formed on the installation side of the screw 88. For this purpose, the workpiece is turned 6 ° around the central axis of the central hole in the direction of the cut. Then, a cutting wheel mounted vertically and parallel to the vertical plane is moved so that the cut coincides with the tangent hole of the first group. This operation to form the platform of the support protrusion 86 is repeated five more times with the rotation of the workpiece by 60 ° around the Central axis of the Central hole.

Then the back side of the protrusion of the cut 85 is formed with a cutting wheel. For this, the workpiece is turned 15 ° around the central axis of the central hole in the direction opposite to the cut. Then, a cutting wheel mounted vertically and parallel to the vertical plane is moved so that the cut coincides with the tangent hole of the first group. This operation to form the back of the protrusion of the cut 85 is repeated five more times with the workpiece turning 60 ° around the central axis of the central hole.

Фрезерный диск 26 готов к работе.A cutting insert 87 of 2.0 mm thickness is made of tool steel, one end of which is sharpened to obtain the appropriate profile. The finished cutting insert 87 is installed on the supporting platform of the protrusion of the cut 85 with the output of the cutting edge of the cutting insert 87 for the dimensions of the outer diameter

-shaped profile, all six are set to the same size around the circumference of the cut and fixed through a spacer 89 with a screw 88. Milling disc 26 is ready for use.

The assembly of the milling unit includes the assembly of the bearing support 23 (see Fig. 3) with two bearings 24 and its installation on the table 1 above the corresponding hole made in it in accordance with the marking. In this case, the bearing support 23, which fully corresponds to the bearing support 63 and its mounting on the table 1, is pre-installed on the table 1 with four bolts 71 (not shown in Fig. 3). Then, from the bottom, into the bore of the bearings 24 and 29, the shaft 21 is inserted with a groove with a diameter of Ф = 40 mm until it stops below from the bottom by the protrusion 22, the end of the inner ring of the bearing 24. In this position, the shaft 21 is temporarily fixed from shifting it down. Then, the lower spacer 25 slides on top of the shaft 21 from the top until it stops against the end of the inner ring of the bearing 29. Then, the lower milling disk 26 slides on top of the shaft 21 to install it on the upper end of the lower spacer 25. Then, the second spacer 25 slides on top of the shaft 21 until it stops it into the lower milling disk 26. Then, on the shaft 21, the first clamping disk 27 is assembled with the emphasis of the end of the inner ring of the bearing 31 at the end of the second spacer 25. The clamping disk 27 is installed with the retaining ring down. Then, the third spacer 25 slides on top of the shaft 21 from the top until the end of the end rests against the end of the inner ring of the bearing 31. Then, the second milling disk 26 slides on top of the shaft 21 until it is installed on the upper end of the third spacer 25. Further, the installation takes place according to the spacer - clamping disk 27 - spacer 25 - milling disk 26 before installing the last clamping disk 27 and the last spacer 25. The last, upper simpleton 25 is pressed with a nut 28 with a thread 36 × 1,5 with emphasis on the upper end of the inner ring of the bearing 31. The first lower spacer 25 the lower milling disk 26 is pressed against the upper end of the inner ring of the upper bearing 29. At the same time, the protrusion 22 of the shaft 21 is pressed against the lower end of the inner ring of the lower bearing 24 of the bearing support 23. Thus, the cutting part of the milling unit is assembled and installed in the bearing support 23. Preliminary fixation the shaft 21 is eliminated from the downward displacement and the bearing support 63 assembled with the cutting part of the milling unit is mounted on the table 1 with the help of four bolts 71 finally. Now it remains with the help of the coupling to install the corresponding drive 14 and 15 on the end of the shaft 21 protruding from the bottom of the table 1. As a coupling, you can use the coupling made according to the invention patent RU No. 2477396. Installation of the drive 14 and 15 can be done using the patent for invention RU No. 2480327.

The number of milling discs 26 and clamping discs 27 depend on the length of the shaft and the height of the spacer 25. The height of the spacer depends on the width of the produced lamella. In FIG. Figure 3 shows an example for the manufacture of five pieces of slats 60 mm wide.

The manufacture of the feeding and moving mechanism, as well as its assembly, is carried out by the manufacture of its components. You can start manufacturing with the manufacture of vertical rotating guides 9, 11, 12 and 13 with their installation on the table 1. The stepped shaft 58 (see Fig. 7) is made of the same material as the stepped shaft 21 and has an installation protrusion 59 of diameter F = 50 mm, which is obtained due to one groove at the top and two grooves at the bottom.

Above, the groove for installing the roller 60 is made with a diameter of Ф = 40 mm and a length of 420 mm. At the bottom, the stepped shaft 58 has one groove with a diameter of Ф = 40 mm for installing two bearings with a length slightly less than the height of two bearings and a second groove with a diameter of Ф = 25 mm over a length of 160 mm for its installation and installation of a driven sprocket 65.

On top, the stepped shaft 58 has a blind threaded hole M22 × 1.25 and a length of 80 mm for installation and fastening of the roller 60, and below a blind threaded hole M16 × 1.25 and a length of 80 mm for mounting it and a driven sprocket 65.

The roller 60 is mounted on the outer diameter Ф = 40 mm and a length of 420 mm of the stepped shaft 58 with its emphasis on the upper end of the protrusion 59 and the roller 60 is pressed to it through the other end using the pressure washer 61 with the corresponding bolt 62. The vertical rotating guide thus assembled is inserted on top of the bearing assembly 63, and on the protruding bottom end of the stepped shaft 58, a driven sprocket 65 is installed through a system of removable and removable compression sleeves 64 and washers and is mounted on the shaft 58 with a corresponding bolt (in FIG. e denotes) focusing the upper movable sleeve 64 similar to the roller 60.

Bearing support 63 (see Fig. 7) is similar to bearing support 23 and the same bearings are installed as bearings 24, 29 and 67, namely bearings SKF 3208 A-2RS1. The holder 68 is a thick-walled hollow cylinder with a height of 60 mm, between the outer wall of which diameter Φ = 120 mm and the inner hole Φ = 80 mm, five coaxial through holes are drilled with a diameter of Φ = 12.5 mm. The corresponding five through holes are drilled in the upper annular flange 69 and the lower rectangular flange 66 during their manufacture.

The upper annular flange 69 is a turned ring with an outer diameter of Φ = 120 mm and an inner hole with a diameter of Φ = 46 mm and a thickness of 20 mm and the corresponding five holes.

The lower rectangular flange 66 is at the same time the base and in plan it represents a rectangular plate 130 × 270 mm in size, 20.0 mm thick with a central hole with a diameter of Ф = 70 mm and five through threaded holes M12 × 1.25 mm around it, corresponding to the holes in the cage wall 68 and in the upper annular flange 69. Moreover, the width of the rectangular flange 66 has a constant size equal to 130 mm, and the length can be less than 270 mm and depends on where it is installed on the table 1. The shape of the rectangular flange 66 can be polygonal and rounded oh, depending on the installation location. So, for example, for the manufacture of a bearing support 23, a length of 170 mm was chosen.

Two bearings 67 are inserted into the sleeve 68. Then, the through holes of the hollow cylinder of the sleeve 68 are mated with the through holes of the upper annular flange 69 and the lower rectangular flange 66 into which the bolts 70 are inserted. The lower flange 66 has threaded holes M12 × 1.25 into which they are screwed five bolts 70. Thus, the assembly of the vertical rotating guides 9, 11, 12 and 13 together with the assembly of the bearing support 63 is completed, and they can be mounted on the table 1.

To do this, through the corresponding hole made in accordance with the marking, the rectangular flange 66 is mounted on the table with the roller 60 up, passing down the driven sprocket 65 through the corresponding hole, and four threaded holes M12 × 1.25 are combined with four holes in the form of a groove made in the corners of the rectangular flange 66. Then through the holes in the form of a groove, bolts 71 with washers are passed and they are baited in the combined four threaded holes M12 × 1.25, made on the table 1. Preset vertical rotating on ruling 9, 11, 12 and 13 completed.

The driven sprockets 65, as well as the drive sprocket 72 (see Fig. 8), have the same design with the number of teeth twenty-one under chain 18 (see Fig. 2) as the chain PR-12,7-18,2- is used 1 with the number of links 175 and a length equal to 2222.5 mm and the corresponding GOST 13 568-97. As the gear motor 16, it is preferable to use a gear motor SEW R27 DT80K2 with P = 0.75; n = 73 rpm; M = 98 Nm.

The gear motor 16 (see Fig. 8) is mounted with four bolts inside the box 20 with the driven sprocket 72 on the protruding end of the shaft 73. The driven sprockets 65 (see Fig. 2), the drive sprocket 72 and the tension sprocket at the end of the two-arm lever tension systems 17 are located at the bottom of table 1 in one plane parallel to the plane of table 1.

One of the manufacturing options of the clamping system 10 can be performed as follows. For the manufacture of the L-shaped lever 36, two rectangular tubes 30 × 30 mm in size are used, one 110 mm long and the other 175 mm. From above, a short pipe is lapped perpendicularly to the first on the right side with a lap and, by welding, are connected together by an integral connection (see Fig. 6). At the free end of the long pipe and at the junction of the pipes, the short pipe is drilled through a through hole with a diameter of F = 24 mm and, having put M12 × 1.25 nuts on them from the outside, they are connected with an integral connection, aligning their holes coaxially. A piece of angle 43 from a profile of 50 × 50 mm and a length of 60 mm is permanently connected to the free end of the short pipe, so that the corner shelf is located below and directed inward to the long pipe and is shifted downward of the L-shaped lever 36. On this protruding part of the corner shelf a through hole with a diameter of Φ = 12 mm was drilled to install the bracket 44 assembly. To install the L-shaped lever 36 on the table 1 through the marking made through threaded holes. One M10 × 1.25 hole for mounting a finger 40 and two M8 × 1 holes for installing a vertical stand 38. The vertical stand 38 is made of a rectangular section of a 30 × 30 mm pipe with a length of 150 mm, to which a thrust bearing is welded from below in the form a plate protruding on one side of the overall dimension of the base of the profile in which two through holes M8 × 1 are drilled to install a vertical stand 38 (not indicated by Fig. 5 and 6).

The bracket 44 is made of three rectangular sheets of steel with a thickness of 25 mm, which by welding are connected together by an integral connection. The first sheet of the center has, assembled in the bracket 44, the size of the rectangle corresponding to the size of the outer shelf of the corner 43 to which it is attached with a bolt 57. The second sheet for the strap 45, assembled in the bracket 44 has a size of a rectangle 50 × 100 with beveled corners on the free end and is located from the back to the center sheet. The third sheet for the strap 46, assembled into the bracket 44, has a rectangle size of 70 × 70 with beveled corners on the free end and is located on the side of the central sheet from the side opposite the protruding shelf of the corner 43 and is slightly offset towards the vertical strut 38.

At the free ends of the strips 45 and 46, stepped through holes are drilled for mounting flush-mounted bearings of the SKF 3204 A-2RS1 type with an emphasis on the outer bearing ring in the protrusion of the stepped through hole. From the displacement of bearings 47 and 48 along the axis of rotation, its fixing is provided on the installation side by means of a bolt and washer, the outer diameter of which during installation overlaps the outer ring of bearings (not shown in Fig. 5 and 6).

The bracket 51 of the pressure bearing 52 is made in the form of a corner with different shelves, both in length and in thickness. The thickness of the shelf on which the pressure bearing 52 is located is 15 mm and has a through hole with a diameter of F = 12 mm under it (pressure bearing 52) installed using a stepped shaft 90 with a diameter of F = 40 mm with M 12 thread at one end. At the other end of the stepped shaft 90 there is a protrusion with a diameter of Ф = 50 mm. As the clamping bearing 52, a bearing of the SKF 3208 A-2RS1 type with an inner diameter of the inner ring Φ = 40 mm is suitable. The stepped shaft 90 with a diameter of F = 40 mm with a threaded end is inserted into the inner ring of the bearing until it stops in its protrusion with a diameter of F = 50 mm. Then, a washer is pushed onto the protruding end, resting on the inner ring of the bearing on the other side, and this assembly is threaded end inserted into the through hole with a diameter of Ф = 12 mm of the bracket 51 from the bottom, the threaded end exits from the top of the bracket 51, and then the assembly is attached to the bracket with an M12 nut with an engraving washer 51.

Two holes are made in a short shelf with a thickness of 25 mm in the form of a protrusion 53 with a length of 30 mm of the bracket 51. One on the left parallel to the axis of rotation of the stepped shaft 90 is blind for a bolt with M12 thread and the second through hole with a diameter of Ф = 16 mm to the right is perpendicular to the direction of movement of the blank 32 under the mounting axis 49.

-образной пластины 56.Installation of the bracket 51 assembly to the strap 46 of the bracket 44 is carried out in the following sequence. In the through hole with a diameter of Ф = 16 mm of the bracket 51 assembled from the side of the pressure bearing 52, a mounting axis 49 is inserted in the form of a bolt with a diameter of Ф = 16 mm and a thread Ml 6 mm at the end. A sleeve 50 is mounted on the protruding end of the mounting axis 49, and then the mounting axis 49 is advanced through the bearing bore 48 until the threaded portion extends beyond the bearing 48 and fastened through a washer similar to sleeve 50 with an engraving washer using nut M16 with a clamp to the ends of the bearing inner ring 48. Thus, the bracket 51 complete with the clamping bearing 52 is installed in the bracket 46 of the bracket 44. Now we connect the plate 54 from below using a bolt M12 with the bracket 51 and then connect its end protruding from under the bracket 45 with zhinoy 55. Another end of the spring 55 connect with an upper portion bent

-shaped plate 56.

To install the bracket 44 in the assembly, the vertical axis of the axis of rotation 37 is combined with the axis of rotation of the bearing 47 (see Fig. 5) and, using a set of bushings and / or washers, the bearing 47 is set to a certain height so that the contact of the pressure bearing 52 is in contact format blank 32 was carried out not higher than the cut level of the second milling disk 26 and not lower than the first milling disk 26 located below. Those. between the bottom and next milling discs 26.

In this case, the vertical installation axis of rotation 37 is mounted on the table 1 with the possibility of its movement into the hole of the table, made in the form of a groove (see Fig. 5). The axis of rotation 37 itself is made in the form of a stepped shaft with threads at the ends and a protrusion for installation from above with emphasis on the inner ring of the bearing 47 through a set of bushings and / or washers located both above and below the inner ring of the bearing 47. It remains to install the spring 39 and screw in the locknut bolt, which is simultaneously the adjusting stop 42.

At the bottom of table 1, a tensioning system 17 of chain 18 is installed, where it is recommended to use Talrep M8 (C) (hook-ring) DIN 1480 as a turnbucket 76. The feeding and moving mechanism is ready for operation.

The operation of the device, in which the method of producing spring slats from the formatted workpiece is carried out, including the operation of the feeding and moving mechanism, the clamping system, milling blocks with milling disks, and the method of moving with the milling and cutting method is implemented as follows.

From the stack of format blanks 32 bent along the radius R, two parallel ends of which are cut in a straight line forming this surface, take the first and set it with parallel trimmed edges vertically upward above the flat guide 6, leaning it against the plates 33 of the vertical guides 7 and 8. B at this time, the gear motor 16 and the drives 14, 15 of the milling units 2 and 3 are turned on. At the same time, the format blank 32 (see Fig. 10) is pressed against the plates 33 with an external force P _vu . This operation can be performed manually or automatically using vacuum suction cups. At the same time, moving it towards the milling blocks 2 and 3, pressing it with its curved side to the vertical guides 7 and 8, let it pass between them and the outer diameter of the pressure bearing 52, ensuring that it touches the concave side of the format blank 32 with a force P _cn . Then comes the advancement of the blank 32 to touch its first end with the roller 60 of the vertical rotating guide 9 of the feeding and moving mechanism. At this time, under the influence of the weight of the format blank 32 and the clamping system 10, it falls down until it touches the protruding part of the untreated end of the flat guide 6. When the curved surface of the format blank 32 hits the rotating roller 60 of the vertical rotary guide 9, its further progress is at a speed set by the rotation speed of the roller 60. Thus, the foundation was laid for the implementation of a method for moving a formatted workpiece using a feed and transfer mechanism. With further movement of the formatted blank 32, its first end gets a concave surface onto the outer pressing surface 30 of the pressure rollers 27 of the milling unit 2 with the simultaneous start of the milling and cutting process. In this case, the milling discs 26 of the milling units 2 and 3 rotate in pairs at each set level in a plane parallel to the plane of the table 1 without moving relative to the format blank 32, and the format blank 32 moves in the direction of rotation. Milling discs 26 rotate at a speed of 3000 rpm. In this case, the milling discs 26 of the milling unit 2 producing cut from the concave surface side have a cutting depth greater than the cutting depth of the milling discs 26 of the milling unit 3 cutting from the side of the curved surface. Along the way, milling begins with the milling disks 26 of the milling unit 2 and ends with the passing milling by milling with the milling disks 26 of the milling unit 3 with the cutting blank 32 being cut between the milling disks 26 of the milling units 2 and 3. The center of rotation of the milling unit 3 is installed from the curved side surface, spaced from the center of rotation of the milling unit 2, making a cut from the side of the concave surface in the direction of movement of the blank 32, by an angle γ equal to 8 ° -12 °. The value of the angle γ depends on the thickness of the formatted workpiece, its bending radius and the size of the milling discs 26 and the features of their design. In our case, a straight line in the plane of the table 1, passing through the axis of rotation of the milling blocks 2 and 3, is located at an angle γ = 10 °.

Further movement of the format blank 32 from the milling unit 3 until it touches the vertical ends of the future slats with the roller 60 of the vertical guide 11 occurs when all cutting edges of the cutting inserts 87 of the milling discs 26 of the milling units 2 and 3 are exposed to it. The impact on the format blank 32 the cutting edges of the cutting plates 87 of the milling discs 26 directed towards the movement of the format blank 32. In this case, the contact of the format blank 32 with the vertical guide 9 and with the end surfaces Numerous rollers 27 occurs along the lines of the vertical horizontal plane of the table 1, and these lines are direct generators of the cylindrical surface of the format blank 32 and are arranged in relation to it as follows. Two extreme from the roller 60 of the vertical guide 9 and the pressure roller 27 of the milling unit 3 are located on the curved side, and the middle from the pressure roller 27 of the milling unit 2 is located between them on the concave side of the format blank 32. This creates conditions for the stable movement of the format blank 32. This is facilitated by rotating milling discs 26 located parallel vertically in planes parallel to the plane of table 1.

In this section of movement of the formatted blank 32, it moves at a speed specified by the speed of rotation of the roller 60 of the vertical guide 9. Note that the further movement of the formatted blank 32 until complete cutting takes place at this constant speed, because the rotation speeds of all four vertical guides 9, 11, 12 and 13 are the same.

When the rear end of the format blank 32 approaches its exit beyond the limits of interaction with the roller 60 of the vertical guide 9, they take the second from the stack of format blanks and set it with parallel cut edges vertically above the surface of the flat rail 6, leaning it against the plates 33 of the vertical guides 7 and 8.

At this time, by moving the rear end of the first format blank 32 between the two milling blocks 2 and 3, the process of passing milling and cutting ends.

But the process of moving the lamellas continues until the lamellas pass the contact of the concave surface with the surface of the cylindrical surface of the roller 60 of the vertical rotating guide 11.

Now, the method for producing spring lamellas from a formatted blank with the simultaneous production of a finished rounded profile of the ribs and a device for its implementation with a feeding and moving mechanism including a clamping system, a milling unit and a milling disk, including a method of moving the formatted blank, as well as a milling and cutting method, has ended.

You can remove the finished lamellas manually or automatically with the help of vacuum suction cups or tacks. For example, the ends of the protruding finished lamellas are tacked immediately after they pass a vertical rotating guide 13 and the lamellas together with the gripping mechanism move at the same speed that coincides with the speed of their longitudinal movement. After passing the finished lamellas of a vertical rotating guide 11, the mechanism abruptly rotates them 30 ° clockwise. Finished lamellas turn out to be in the middle of the straight line connecting the vertical rotating guides 13 and 12. Then they are quickly removed by this mechanism from the device along the reversal beam and then transferred and stacked according to the intended program. At the completion of the cutting process and completion of work, the rotation and displacement mechanisms are switched off while the brakes are simultaneously engaged by pressing the brake plates of the brakes 4 and 5 to the outer pressure surfaces 30 of the pressure rollers 27 of the milling units 2 and 3. The process for implementing the method for producing lamellas will be more rational if the second and The following format blanks will be fed end to end. In this case, the advancement proceeds at a speed specified by the rotation speed of the rollers 60. Usually, the height of the installed format blank is higher than the level of action of the milling blocks, therefore, the height of the milling blocks is made a multiple of the height of the format blank. In this case, the rest of the format blank is passed through the device again. The narrow lamella obtained in this way from a flat guide 6 to the plane of action of the lower pair of milling disks 26 goes to crafts.

Typically, for this type of device, vacuum sensors are installed that do not allow the device to start operation when the cover 91 is removed and the saw product suction system is off. They are implemented in this device.

In FIG. 11 shows a General view of the device, the removal of the casing 91 of which is carried out using the handles 92. The casing 91 is equipped with nozzles 93 of the suction system of the sawn products and is mounted on the table 1 using the fastening screws 94.

In the manual feed mode of the blank 32, it is provided for the assembly of the device to be mounted on the stand 95 at an angle β, which may vary depending on the personal data of the maintenance personnel.

Using this group of inventions, two thousand slats per hour can be produced.

Thus, the proposed group of inventions will reduce the number of preparatory operations and exclude additional equipment in the preparation of format blanks for the manufacture of slats. This simplifies the design of the device, reduces its metal consumption and increases its compactness. The time for feeding and moving, milling and cutting is reduced, serviceability is increased, maintenance is simplified, and expensive electronic equipment and a hydraulic system are eliminated. In addition, energy costs are reduced, which ultimately affects the reduction in the cost of obtaining the final product.
