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 manufacturing a rotationally symmetrical shaped article, which has a cylindrical, concentric hub axially closed on one side, in a shaping process is performed such that at least one pressure roll is in contact with a rotating, closed, planar circular blank sheet and presses the material of the blank radially from the outside inward against a projecting part that runs upright on the circular blank such that the thickness of the circular blank decreases and the hub including a blind hole is formed.
