Abstract:
A method for chipless production of a rotationally symmetrical body from a circular sheet metal blank shapes the circular sheet metal blank into a pot-shaped body by pressing or pressure rolling around an inner mandrel, and a hub-shaped projection protruding outward from the base of the pot-shaped body is molded on by pressing around a central projection. The circular sheet metal blank is clamped only in the radial inner region of the blank in the axial direction between the inner mandrel and at least one projection during the shaping process.
