Abrégé

The molding of longitudinal gearings into the walls of pot-shaped and hollow-cylindrical metal parts, which are mounted on receiving bolts and shaping punches, requires radial adjustment positions, which are adjusted and aligned so as to be precisely repeatable, of the tooth profile pressing rollers (10) in their different radial working positions. The bearing journals (14) on both sides of the axle bolts (12) have a polygonal cross-sectional shape, including plane bearing journal, adjustment and guidance surfaces (17), with which, held in a mounting position between a bearing ring (24), a supporting and adjusting ring (20), and a covering ring (25), they form support bearings, which can be adjusted in a radially directed stepped manner. For adjusting and positioning in other work positions of the tooth profile pressing rollers (10), the bearing journals (14) only need to be relocated or replugged to an adjacent radially directed mounting position (15) without the need for an assortment of exchange adjustment elements. Application is in particular found in tooth profile molding in disk carriers.

The invention relates to a method for producing a profile (2) at an edge region of a sheet metal part (1), wherein the sheet metal part (1) can be produced from a blank (3) having a thickness (s) and the profile (2) by shearing. According to the invention, the edge region is thickened by at least one swaging process to a profile height (h) > (s) and the profile (2) is then cut in the thickened edge region (5a), wherein the thickened edge region (5a) is supported perpendicular to the cutting direction.

Abrégé

The invention relates to a method 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, and a corresponding device. The aim of the invention is to devise a method and a device which allow the production of profile rollers (28), said rollers controlling the true running, dimensional accuracy and the surface of the cup-shaped sheet material component (12.1; 12.2) 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 according to the invention is characterized in that an untoothed cup-shaped sheet material component (12.1; 12.2) is slid onto a pick-up mandrel (20) 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, thereby pressing the material into the grooves of the pick-up mandrel, and a displacement of every profile roller (28) of the set of profile rollers towards the pick-up mandrel (20) taking place in the region of the open end of the cup-shaped sheet material component to be formed, thereby forming the desired profile of the forming 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.
