Definitions

  • the invention relates to a profile and thread rolling machine with a machine frame in a stand configuration and with at least two roller supports arranged on an approximately vertical side wall and movable by adjusting devices with rolling tools, to which feed devices for the workpiece are assigned.
  • roller carriers are designed as levers which can be pivoted relative to one another, which are guided on supporting bolts which run perpendicular to the side wall and are acted upon by pressure cylinders. Due to their design, machines of this type require the rolling tools to be loaded from below.
  • the invention has for its object to design a profile and thread rolling machine of the type mentioned in such a way that there is extensive freedom for the arrangement of additional units and in addition there is the possibility of an embodiment which allows the machining of several workpieces.
  • the invention consists in solving this problem in a profile and thread rolling machine of the type mentioned at the outset that the roller supports are designed as slide guides which are guided on supporting columns which run horizontally and parallel to the side wall and which have yoke plates which project freely from the upper region of the side wall are worn.
  • This configuration is based on the knowledge that the column guides known in principle from other thread rolling devices can act in a particularly advantageous manner if they protrude freely from approximately perpendicular side surfaces, because then the possibility of access to the rolling tools or to the roller carriers from below and is from above; there are also options for using multiple processing tools.
  • Such an embodiment also allows, depending on the intended use, to provide different or several support column units. This allows the new machines to be used universally, in particular when the yoke plates are firmly attached to a mounting plate which can be firmly connected to a side wall of the machine stand.
  • the slide guides can advantageously be designed as guide plates which can be displaced by mechanical adjusting devices and / or by pressure cylinders which can be actuated hydraulically or pneumatically.
  • These adjustment devices can be mounted on the yoke plates and the support columns can be used as tie rods that are continuous over the entire width of the machine be trained.
  • the yoke plates only have to bear the weight of the support columns and roller carriers, but not the machining forces. The weight of a machine designed in this way and the space requirement can therefore be kept relatively low.
  • the roller axes can run horizontally and perpendicular to the axes of the support columns. In another version, they can run vertically, but also perpendicular to the axes of the support columns.
  • the rollers are then driven by angular gears, which can be easily arranged between the support columns.
  • four support columns arranged at the corners of a rectangle are provided, two of which each run in planes parallel to the end wall.
  • a lighter, but still better in terms of accessibility embodiment provides three support columns, two of which are arranged one below the other and in the region of the side wall, while the third lies in a plane through the upper of the support columns lying in the region of the side wall and in is a plane perpendicular to the plane in which the other two support columns lie.
  • This embodiment is distinguished by the fact that on the side facing away from the machine frame there is only one support column, which is located at the top, by particularly good accessibility.
  • a machine frame 1 is shown in a stator design, which in a manner to be explained later receives drive motors 2, possibly with a gear and synchronizing device for two rolling tools 3, which can be rotated by articulated shafts 4 from the associated gearboxes or drives.
  • the rollers 3 are each mounted on a roller carrier 5, which consists of two bearing 6 for the shaft 7 of the rollers bearing cheeks 8 and guide plates 9, on which the bearing cheeks 8 via a Zwi leg piece 10 are firmly attached.
  • Both guide plates 9 are each slidably supported by three guide sleeves 11 on support columns 12 which extend parallel to one another and are arranged such that two of them, 12 ', 12 ", lie approximately underneath one another and the third, 12''', with its axis lies in a plane which runs horizontally through the axis of the upper 12 1 of the other support columns and is approximately perpendicular to the approximately vertical plane in which the axes of the two other support columns 12 'and 12''lie 12 ', "12" and 12 “” in turn are supported at their two ends in yoke plates 14, which in turn are firmly connected to a mounting plate 15 which is fixedly attached to the side wall 16 of the machine stand 1 which runs vertically in the exemplary embodiment.
  • an automatic lifting device 18 is provided for a workpiece 19 to be machined.
  • This lifting device 18 is designed in a known manner. It consists of a support plate 20 with prismatic guides 21 and centering devices 22 for the workpiece 19 arranged thereon.
  • the support plate 20 itself is mounted on guide columns 23 so as to be vertically displaceable and can be lifted cyclically with the aid of a pneumatically or hydraulically actuated lifting cylinder 24 so that the workpiece 19 in each case is performed in a known manner between the two rolling tools 9.
  • the entire lifting device 18 is arranged on a shoulder 25 on its vertical side wall, which extends the side wall 16 approximately downwards.
  • the two guide plates 9 of the roller carriers 5 are connected — with the aid of the intermediate pieces 10 — likewise in a known manner — to pneumatic or hydraulic pressure cylinders 26, the axis 27 of which runs parallel to the support columns 12 ′, 12 ′′ and through the axes of the rolling tools 3.
  • the impression cylinders like therefore are supported on the yoke plates 14 via threaded spindles 28 and can be adjusted in position on the support columns 12 ', 12'',12''' by means of the handwheels 29 together with the roller carriers 5.
  • the adaptation of the rolling tools 3 to the workpieces 19 to be machined can therefore be adjusted by hand before the actual rolling process.
  • the pressure required for the machining process is brought about via the cylinders 26.
  • a control panel 31 is mounted on a control cabinet 30, which is electrically connected to the drives in a manner not shown, because in the usual way.
  • the drive of the rollers 3 and their synchronization, their speed control and the like. also take place in a known manner. This data can be entered on the control panel 31.
  • the new machine has the advantage that below - but also above - the support column device there is a lot of space for the installation of additional units.
  • the new machine can therefore be used to automate the feeding of workpieces in any desired manner.
  • the drive of the rollers 3 leads through an opening 33 in the side wall 16 and in the receiving plate 15.
  • the cardan shafts 4 are telescopic in a known manner. Their length can therefore be adjusted when the position of the rollers 3 is adjusted.
  • the forces exerted during the rolling process are absorbed by the support columns 12 ', 12' 'and 12' '' which act as tie rods and are fastened to the yoke plates 14 with nuts 34 for this purpose.
  • These support columns can be dimensioned so that there is sufficient rigidity of this guide unit.
  • rollers 3 ' are driven by an angular gear 36 which is driven by the universal joint shafts 4 in the same way as was also provided in the embodiment of FIGS. 1 to 4.
  • This position of the rollers 3 ' enables workpieces to be fed in from below via a lifting device 37, specifically in the direction parallel to the axes 35 of the rollers 3'.
  • FIG. 6 shows a modified embodiment.
  • several rollers 3 "are driven via the angular gear 36 and a schematically indicated pinion 38, so that, for example, machining with three rollers lying on the circumference of the workpiece is possible.
  • machining with three rollers lying on the circumference of the workpiece is possible.
  • the support column arrangement in turn has the advantage that it offers extensive freedom for the accommodation and the drive of the rolling tools and the possibility to arrange additional units for easy feeding and removal of workpieces below.
  • FIG. 7 to 10 show another embodiment of a Profile and thread rolling machine according to the invention, but in which - since the function is the same - the same parts and with the same reference numerals as in the previously explained figures are used.
  • two processing stations I and II are provided on a machine frame 1.
  • the structural unit formed from the mounting plates 15 and support columns 12 ', 12'',12''' perpendicular to the direction of the axes of the support columns 12 ', 12 ", 12th is achieved in that the upper region of the side wall 16, on which the mounting plate 15 is mounted, is part of a slide 51 which can be moved on the machine frame 1 in the direction of the arrows 50 and which can be moved, for example, by hand actuatable adjusting spindle 52 can be moved into a specific position relative to the transport device and lifting device 18.
  • the slide 51 is held on the guide rails 53 on the machine frame 1, which are not shown in detail.
  • a different structural unit with a different arrangement of the support columns 12 ', 12 ", 12" "and the tools than in station I is provided at station II.
  • this is for the purpose of Adjustment of the tool-operated handwheel 29, the position of which roughly corresponds to that of the tools behind it, is arranged in the left region of the yoke plates 14, in which there are also two supporting columns 12 'and 12' 'which are located one below the other and absorb the deformation forces.
  • the handwheel 29 lies in the right area of the yoke plates 14, in which the two supporting columns 12 'and 12 "are also arranged cooperates with lifting devices 18 for the workpieces 19.
  • the lifting devices 18 each move into the machining position
  • Lifted workpieces 19 are processed in station I at the left end (for example with a thread) and in station II in the area of their right end.
  • the workpieces 19 therefore maintain their position relative to the machine frame 1 during transport and processing, while the processing tools successively assume different positions relative to the workpiece 19. The automatic processing of workpieces in one machine is therefore possible.
  • the new design with sliding carriages 51 additionally opens up the possibility of being able to machine workpieces of different lengths or those that have to be machined differently, with one machine, without having to convert the machining assemblies.
  • a workpiece can be provided with a thread of 20 mm or with a thread up to 110 mm at one end. For this purpose, only the tool assembly is brought into the required relative position to the firmly guided workpiece with the aid of the slide 51.
  • This option enables the machine to be quickly converted to processing different workpieces. It is not necessary to add or remove the processing unit. Of course, it is not always necessary to provide two or more stations on one machine in order to adapt to different machining lengths. For certain workpieces of short length, the use of only one station can be sufficient, which successively carries out machining operations in different positions on a workpiece. However, it is also possible to convert the machine to machining different workpieces, for example of different lengths, which arrive successively on the transport device 55. This also opens up the fully automatic processing of workpieces of different lengths with one or more stations, if the manual spindle adjustment is carried out automatically by the Trans Port device from controlled adjustment device for the carriage 51 is replaced.
  • the arrangement of the processing unit on a slide therefore allows extensive flexibility when using the new machines.
