| 20110079066 | METHOD FOR PRODUCING AN INTERNALLY OR EXTERNALLY TOOTHED CUP-SHAPED SHEET MATERIAL COMPONENT AND CORRESPONDING DEVICE - A method and a device for producing an internally or externally toothed cup-shaped sheet material component with teeth that run in parallel to the center axis of the cup, especially of a clutch plate carrier. The method and device allow the production of profile rollers, the rollers controlling the true running, dimensional accuracy and the surface of the cup-shaped sheet material component having an internally and externally profiled wall in the shape of teeth, in such a manner that they guarantee a specifically variable position during production. The method is characterized in that an untoothed cup-shaped sheet material component is slid onto a pick-up mandrel which has an external toothing corresponding to the internal toothing of the sheet material component to be produced and the external profile is then rolled onto the cup-shaped sheet material component by pressing the cup-shaped sheet material component together with the pick-up mandrel by means of a set of profile rollers rolling off in parallel to the center axis on the sheet material component while exerting a radial pressure. This results in pressing the material into the grooves of the pick-up mandrel, and a displacement of every profile roller of the set of profile rollers toward the pick-up mandrel taking place in the region of the open end of the cup-shaped sheet material component to be formed. This process thereby forms the desired profile of the internally and externally toothed region at the open end of the sheet material component due to a pressure relief, and removal of the sheet material component so treated. | 04-07-2011 |
