Abstract: A method for roll-forming disk carriers or the like, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in their interior, which roll out the disk carrier to be formed with their outer circumference and thus impart toothing on the disk carrier to be formed, wherein the forming depth of the profile rollers at the disk carrier to be formed is designed in such a way that a narrow, peripheral, self-contained, unformed bridge remains between the inner diameter and the outer diameter of the toothing, wherein the bridge increases the engine-speed strength of the disk carrier as a hoop band cylinder that is integrated into the toothing.
Abstract: A method for producing an internally and/or externally toothed pot-shaped sheet metal part having teeth extending toward the pot center axis, wherein an un-toothed pot-shaped sheet metal part is inserted into a die and then, by means of a relative movement between the sheet metal part and associated profile rollers, a profile is rolled onto the pot-shaped sheet metal part by the profile rollers applied to the sheet metal part and thus alternating internal and external gear teeth are applied to the sheet metal part, wherein the profile rollers form the sheet metal part oriented radially from the inside toward the outside, in that the profile rollers roll along the inner circumference of the sheet metal part.
Abstract: A method for precision cutting of workpieces using a press which includes a press frame, in the press opening of which press frame a press ram, that works against a press table, is movably driven, wherein at least one of the press tools is formed as a cutting tool that includes a cutting punch, a downholder, a cutting die and a counter support. The cutting tool operates as a precision cutting tool. A lower tool part of the cutting tool includes a controlled retaining module that retains the counter support in a certain press ram position to enable ejecting the scrap.
Abstract: A method is provided for producing a clinch-rivet connection using a rotary oscillating movement for connecting two metal components, wherein via the oscillating movement by means of forming rollers, a vertical, and simultaneously, a horizontal deformation is carried out, wherein one of the components has a preformed, flat, tab-like arc web, and the second component is provided with an at least partially V-shaped arc slot, which allows the accommodation of the preformed, flat, tab-like arc web, and via radial oscillating movement, the forming roller presses the arc web into the arced slot by superimposed axial movement, wherein the outer circumference of the forming rollers is provided with a wedge-shaped profile, and the oscillating movement of each forming roller with a specific pendulum path across the arc web does not exceed the length of the arc web.
Abstract: A method and a device for producing an internally or externally toothed cup-shaped (body) sheet material component with alternating teeth and grooves that run in parallel to the center axis of the cup, especially of a clutch plate carrier. The method and device allow the use 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. 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 while exerting a radial pressure.
