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.

Method for the chipless production of a rotationally symmetrical body from a circular sheet metal blank

A method for producing rotationally symmetric structural components of metal, in particular steel, is provided. A blank is arranged in a torsion-proof manner on a first receptacle, the receptacle is rotated about a rotation axis so that the blank is caused to rotate about this rotation axis, at least one linear shaping element with a contour having at least partially an unrolled external contour of the rotationally symmetric structural component or a preform of the structural component is moved tangentially to the surface of the synchronously rotating blank, and the linear shaping element is at the same time pressed against the blank so that during the tangential movement the contour of the linear shaping element is formed at least partially into the blank. A kingpin or link pin of a connection link with a connection shaft and a link outer part is produced.
