Definitions

  • the invention relates to an apparatus and a method for producing longitudinal grooves in cylindrical workpieces.
  • profile bodies such as disc carriers of clutches, toothed belt pulleys or similar workpieces with a cylindrical basic structure
  • high accuracies and precision are often required. In particular, it depends on the accuracy of the concentricity and the surface quality.
  • the workpieces described are high-quality production parts, which are produced in large quantities. Thus, in addition to the qualitative characteristics, the costs and the output are important criteria in a production plant for such workpieces.
  • a rolling process takes place in which the profile rollers press the desired outer profile into the lateral surface of the workpiece.
  • the profile rollers are arranged in a lower tool along the circumference of the workpiece to be machined. If the workpiece is pressed between the rollers by means of an upper tool fastened to the plunger of the press, these are supported on support rollers with appropriate mounting.
  • the lower tool can be constructed rotationally symmetrical, wherein the profile of the workpiece generating individual profile rollers are regularly distributed at a uniform angle to each other along the circumference of the workpiece.
  • an upper punch is arranged in a tool upper part, at the lower end of a roll punch is arranged, which carries the component to be deformed.
  • a roll punch is arranged, which carries the component to be deformed.
  • opposite segment discs are arranged, which are rotatably mounted in housing-fixed bearing shells.
  • segment discs each consist of a circle segment, wherein the segment disc are rotatably mounted in a single housing-fixed axis of rotation and roll on a circular rolling track on the outer circumference of the component to be deformed.
  • the invention is therefore based on the object of further developing a method and a device of the shape that the profiled disks used can be driven on different motion curves, which are not necessarily on a circular path.
  • the invention is characterized by the technical teaching of claim 1.
  • the present invention is not limited to the arrangement of two spaced-apart connecting rods. It is also possible instead of two To use connecting rods of their three or more to achieve even better storage of the profile disc.
  • the effective connecting rod length is adjustable.
  • a screw connection is arranged, which forms the distance between the profiled disk side axis of rotation and the bearing shell side bearing axis changeable.
  • the two connecting rods can be set completely independently.
  • FIG. 1 from an upper punch 9, which is driven displaceably via a drive not shown in the direction of its longitudinal axis.
  • Each profiled disc 4 is guided by two spaced-apart connecting rods 1 and 2 in their rolling movement.
  • Gem. FIG. 7 thus forms the one end of the connecting rod 1, 2 each have a rotation axis 17 in the region of the profile disk 4, while the opposite end of the connecting rod 1, 2 forms a bearing axis 16 in a housing-fixed bearing shell 3.
  • FIG. 1 the lowest position of a lifting floor 5 is shown. This serves to set with its stop edge 26 at the respective lower end of the profile disc 4 and support it. In FIG. 1 already the finished deformed state of a component 11 is shown, because the lifting floor 5 is in its lowest position and the profiled disc 4 is supported on the stop edge 26.
  • the upper punch 9 moves back upwards and follows the lifting base 5 so as to bring the profiled discs 4 back into their raised position.
  • a partial lifter 6 is arranged opposite in the axial direction, which is also slidably held in the receiving bore of the machine housing 25 and carries an intermediate bolt 10 at its lower end.
  • the partial lifter 6 is intended for ejecting the deformed component 11 and conveys the deformed component 11 upwards when the upper punch 9 has moved back to be able to remove the component from the central receiving bore in the machine housing 25.
  • the movement sequence for the deformation of a component 11 with two nested teeth 12, 13 is based on FIGS. 2 to 5 shown.
  • FIG. 3 Now comes the component to be deformed in the region of a contact point 22 with the profiled disks 4 in contact and by friction, the profiled disks 4 are taken down in the direction of arrow 20 and roll with the introduction of radially inwardly directed longitudinal grooves deforming on the outer circumference of the component. This is in FIG. 4 shown.
  • FIG. 4 shows the lowest position, approximately as shown FIG. 1 corresponds, in which the component 11 to be deformed with the two staggered teeth 12, 13 is provided.
  • FIG. 5 where it can be seen that the teeth 12, 13 are arranged offset from one another on the circumference.
  • FIG. 6 shows a first way to adjust the length of the respective connecting rod 1, 2.
  • an intermediate piece 23 is loosely mounted in the bearing shell and this results a Verstellspiel 15 in relation to an oppositely arranged and adjustable trained adjusting wedge 14th
  • each connecting rod is formed in two parts, wherein one part is designed as a screw sleeve and the other part as a screw.
  • an adjustable eccentric bush is arranged in the region of the bearing shell 3, specifically in the region of the bearing axis 16.
  • FIG. 7 shows the movement curve of the profile disc 4, which deviates greatly from the movement curve of a circular path.
  • the profile disc 4 moves in the direction of arrow 18 upwards and that according to a somewhat flat, non-circular motion curve, this profile curve 24 therefore follows no circular path, but rather a movement curve whose radius of curvature is smaller than the circular path, the faster immersion movements of the profile disc to achieve on the component to be deformed 11 and in a corresponding manner, a faster lifting movement of the profiled disk of the component 11.
