Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a decorative pattern flat processing that can enhance the decorative effect by applying patterns such as polished patterns to stainless steel or aluminum plates and other flat surfaces. It is related to the device.

(Conventional technology) Traditionally, as a means of processing decorative patterns on the finished surface of metal plates, etc., the patterning equipment used mainly by hand to press patterning tools, but the work efficiency has been greatly improved, and mass production is available at low prices through mass production processing. There have been many changes in the improvement of equipment, including processing equipment. Among these, the configuration disclosed in Japanese Patent Publication No. 52-12438 has been proposed as an automatic device that eliminates the drawbacks of the conventional devices. This patterning device includes a feeding device that is arranged horizontally on a machine stand and intermittently transports a metal plate having a predetermined width, and a patterning device that is arranged so as to be able to rise and fall on a metal plate transfer path. A driving device for simultaneously rotating a plurality of patterned grindstones provided in the device, and a patterning device arranged in a line at predetermined intervals and each having a patterned grindstone at its lower end, each time the intermittent feeding device is operated. 1/ of the grinding wheel spacing
This device is equipped with a lateral swinging mechanism that reciprocates sideways by a distance of 2, making it possible to form polished patterns such as scales on the surface of a metal plate with high work efficiency and uniformly aligned decorative patterns. .

In addition, Japanese Utility Model Publication No. 57-23081 has been proposed as a partial modification of the above means, but the main difference from the former is that the patterning device is moved to the side by a distance of 1/2 of the distance between the grinding wheels. Instead of the reciprocating means, a lateral swinging device for reciprocating the feeding device by the same distance is added, and the operation and effect are not particularly improved.

(Problems to be solved by the invention) This invention allows the scale pattern to be processed by the above-mentioned automatic patterning device to be processed by intermittently feeding the processing plane without providing a grindstone or a lateral swinging mechanism of an intermittent feeding device. It has a configuration that allows it to be formed simply by cutting the pattern, and it is also equipped with multiple rotating axes that can be used not only with a grindstone but also with other appropriate patterning tools, and can be moved vertically and horizontally on the processing plane. To obtain a high-quality, highly efficient decorative pattern plane processing device that is capable of processing various patterns formed on the surface of the machine and has an automatic control means that can easily and automatically execute a decorative pattern processing program by setting a processing program for the decorative pattern. That is.

[Structure of the idea]

(Means for Solving the Problems) In order to achieve the above-mentioned purpose, this invention has been developed to move the processing plane across the movement path of the processing plane in a direction perpendicular to the transfer direction, to move freely at arbitrary intervals, and to form the processing plane in a line. A plurality of rotating shafts are arranged in two rows in the transfer direction, and a driving device is provided for driving each rotating shaft of a patterning device, the lower end of which is provided with a patterning tool such as a grindstone, a wire brush, etc. In cooperation with a plane transfer device that feeds the machining plane intermittently or continuously by a predetermined distance, the above-mentioned pattern machining tools are alternately raised and lowered row by row, and guided to the machining plane with the required row spacing and required inclination angle. , and is provided with a guiding device that presses the material into pattern processing.

(Operation) The operation of this invention will be explained with reference to the drawings of the embodiment.

In this process, the pattern processing tools 18 are attached to the lower ends of a plurality of rotating shafts 17 in the shape of a tuft as shown in FIG. be done.

The spindle head 15 is mounted on a portal-shaped frame carriage 9, and is connected to a multi-shaft unit 16 in the head 15 via a drive spline shaft 13 connected to a drive device 14 installed at the top so that it can move horizontally and freely up and down.
The rotary shaft 17 is simultaneously driven through.

On the other hand, the machining plane S of the workpiece is set on a table 5 which can be moved back and forth intermittently or continuously around the center of the bed 3 of the gate-shaped frame, and pattern machining tools 18 arranged in two rows in orthogonal directions are placed in each row. Alternately lower the processing center to the required processing center position on the processing plane S, perform pattern processing, and raise it in conjunction with the feeding of the table 5 to create the desired pattern on the processing plane S.
Form on top.

As shown in FIGS. 4 and 5, the operation of the guiding device 38 that guides the rotary shaft 17 to descend to a required machining center position on the machining plane S will be explained below, for example, when machining a scale pattern. This will be explained as an example.

First, as shown in Fig. 4, the edge of the machining plane S is set so as to be perpendicular to the transport direction of the machining plane S, and the servo motor MS is controlled so that the table 5 can be intermittently fed by the distance equal to the distance between the grinding wheels. Input the command into the control panel P. The first row of pattern processing tools 18

As shown in the diagram, the second row of grindstones are set so that a pattern is formed at a position horizontally shifted from the first row of grindstones by 1/2 of the distance between the grindstones.

Next, as shown in FIG. 5, the grindstone 18 is guided together with its rotating shaft 17, and the plurality of grindstones in the first row move in the return direction opposite to the forward feeding direction of the table 5, which is indicated by arrow Y in the figure. The machine descends while moving, and adjusts the required row spacing from the mounting center position of the first and second row spindle heads 15 to the machining plane S.
At the 9th grinding wheel, the grinding wheel is guided to a processing center position adjusted to be separated by 1/2 of the grinding wheel interval d, and is pressed against the processing plane S by a required inclination angle θ so as to produce uneven contact with respect to the conveying direction. The pattern shown in Figure A is processed. At this time, as shown in FIG. 8, each rotating shaft is fitted into the multi-axis unit 16 by an intermediate shaft 36 having a spline that is freely movable in the axial direction, and is driven without being held by the vertical movement of the rotating shaft 17. The pattern processing tool 18 attached to the lower end rotates,
Perform the desired pattern processing.

Next, the first row of grindstones 18 return to the original first row mounting center position while rising.

The plurality of grindstones 18 in the second row are lowered while moving in the same direction as the forward direction y of the table, and the processing center is located at a processing center that is 1/2 the distance between the grindstones from the processing center position where the first row was previously carved. The pattern shown in FIG. 9(b) can be formed by guiding it to the position ' and pressing it against the processing plane S.

Next, the second row of grinding wheels 18 is raised to return to the original installation center position, and then, if necessary, the spindle unit 12 is moved by the stroke necessary to process the above-mentioned pattern over the width of the processing plane S.
is transferred laterally and the above processing procedure is repeated.

When the processing steps for the patterns in the first and second rows are completed in this way, the processing plane S on the table 5 is moved forward by intermittent feeding by a distance equal to the distance between the grinding wheels, and the same procedure as above is repeated. As a result, a continuous scale pattern can be formed accurately and with good workability, as shown in FIG. 9C.

are arranged in parallel at the front and rear of the lower surface of the head 15, and fitted into mounting blocks 29 that can rotatably guide a plurality of rotating shafts in the second and first rows in the front and rear, respectively, and at predetermined intervals in the axial direction. Guide plates 23a and 23b are integrally formed by screwing a collar 30 that can set the rotation axis position, and a pneumatic drive cylinder 2 is attached to the front or rear end of the guide plates 20a and 20b.
4 coupling rods 25 are connected in a freely pushable manner, and the rotating shafts 17 of the first and second rows are guided up and down via plate cams 21 while moving them forward or backward separately, and are attached to the lower end of the rotating shafts 17. The grindstone 18 has the function of guiding the grindstone 18 from a predetermined mounting center position, '' to a machining center position, ', which is located at a predetermined interval.

Note that when the grindstone 18 is pressed against the processing plane S,
By making a scale pattern slightly inclined to the plane and forming a pattern on one side, when pressing vertically to create a scale pattern on a patterned object, the area overlapping the previously engraved pattern is It is possible to obtain beautiful scale patterns and the like while avoiding the problems that occur because the scales are difficult to erase.

FIG. 5 shows the inclination θ of the rotary shaft 17 with respect to the machining plane S, and shows the adjustment bolt 34 of the angle adjustment block 33 attached to the outer end of the support block 27 at the guide shaft end 32 of the guide shaft 28 shown in FIG. It is configured such that it can be set by adjusting the angle and referring to the angle position indicator plate 35 for the inclination angle.

In addition, although the above explanation has explained the processing effect of the scale pattern, it is also possible to
By repeatedly moving the upper machining plane S forward or backward intermittently or continuously, it is possible to obtain various machining patterns in combination with the change in the position settings of the two rows of grindstones 18 mentioned above. We have automated these operations by attaching a computer-based numerical control device, and added a CRT graphic display device that allows you to input and track machining programs.The effect is that these complex patterns can be easily mass-produced through interaction. is big.
