Abstract

A method for producing a pot-shaped housing part, especially for a hub part of a hybrid drive. The housing part has a bottom and a wall extending away from the bottom. An outer face of the wall extends approximately up to an outer face of the bottom, with the outer face of the bottom facing away from a free edge of the wall. The method includes the steps of clamping the radially inner zone of a blank in a workpiece holder, so that a radially outer zone of the blank directly adjoining the radially inner zone is free, and folding the radially outer zone of the blank towards and against a contact surface of the workpiece holder by means of a forming process until the outer face of the radially outer zone extends at least up to and preferably beyond the outer face of the radially inner zone.
