Definitions

  • the invention relates to a rolling method and a tool for the production of cylindrical workpieces, with longitudinal grooves, by means of forming rollers with improved storage.
  • an optional integrated in the tool drawing stage should be upstream of the actual rolling process.
  • 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.
  • accuracy and surface quality are important.
  • DE 20 17 709 A1 discloses a suitable method.
  • a special rolling tool makes it possible to produce the workpiece from a blank having a smooth outer contour by means of a press, with each press stroke forming a workpiece from a blank. With each press stroke, 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 ümfanges 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 built rotationally symmetrical, wherein the profile of the workpiece generating individual profile rollers are regularly distributed at a uniform angle to each other along the Ümfanges of the workpiece.
  • the individual grooves produced by the respective profile rollers are virtually identical to one another. In particular, a paragraph-free contour is achieved.
  • a further disadvantage in the embodiment described above lies in the structural design of the profile roller support via the support rollers. Although this design allows a reduced profile roller diameter, but is structurally very complex and costly due to the arrangement of the support rollers intensive. In addition, this results in a large height of the tool.
  • the invention has for its object to develop a method and a tool in which both the forming of a board to a blank, as well as the roll forming takes place on the blank in a common device during a press stroke.
  • the height of the tool should be reduced by a new type of roller bearing profile.
  • the invention is based on the idea to use the downward stroke of a forming press for a combined forming process, consists of deep drawing and Rollumformen within a tool. It has the advantageous effect that the height of the tool part, which is provided for the roll forming, is significantly reduced by a novel profile roller bearing.
  • the storage of the profile rolls consists of two halves of the bearing shell, which surround the profile rolls on the predominant part of the circumference of the profile rolls. On the workpiece side facing the profile rollers and the bearing shell halves protrude. Between the profile rollers and the bearing shells lubricant is introduced via a pressure lubrication.
  • Bearing halves are preferably made solid and only slightly higher in height than the scope of the profile rollers. This makes it possible to attach a draw ring in the upper area of the tool. This drawing ring, together with the stamp upper part, which is firmly connected to the plunger, the task of deep-drawing required for the rolling cylindrical blank from a flat board. This is preferably done without a sheet holder. However, the structure of the tool also allows it to perform the drawing process by means of an additionally installed plate holder.
  • FIG. 1 shows the tool 1 according to the invention in a sectional view.
  • the tool 1 consists of a drawing unit 6 and a roller unit 7.
  • the drawing unit 6 in turn consists of a punch upper part 2, which is fixedly connected to the plunger 4 and a punch base 3, which is vertically movable via the lifting unit 5.
  • FIG. 2 shows a position during the roll forming process.
  • the roller unit 7 with the upper bearing shell 11 and the lower bearing shell 12 can be seen:
  • the two bearing shell halves 11, 12 serve to receive or support the profile rollers 13. These profile rollers 13 are distributed around the circumference of the roller unit 7.
  • the blank 10 is now passed by the vertical downward movement of the plunger 4 with the punch upper part 2 of the profile rollers and thereby receives the resulting from the arrangement of the profile rollers L Lucassnutenprofil on the outer diameter.
  • a lubrication connection 14 can be seen at the outer edge of the tool 1 according to the invention.
  • this lubrication connection 14 and via the lubrication line 15 is pressed by means of a pressure lubrication lubricant between the bearing shell halves 11, 12 and the profile rollers.
  • This lubricant envelops the profile rollers 13 and, in the area in which the profile rollers 13 engage the blank 10, emerges from the bearing shells and is supplied to a lubricant circuit.
  • the lubricant outlet in the area of forming favors the roll forming process and results in a quality improvement of the roller result.
  • the plunger 4 moves with the upper punch part 2 back up, while the finished formed workpiece is also driven by the lifting unit 5 upwards. Subsequently, the workpiece 10 can be gripped by an automation device and transported further. After a new board 8 is inserted into the tool 1 according to the invention, the combined drawing and roll forming can start anew.
  • the rolling unit 7 can be arranged several times one above the other so as to enable multi-stage roll forming. It is also conceivable that the drawing unit 6 is additionally equipped with a regulated sheet holder.
