发明名称 METHOD FOR THE PRODUCTION OF A POT-SHAPED HOUSING PART, AND POT-SHAPED HOUSING PART, ESPECIALLY FOR A HUB PART OF A HYBRID DRIVE
摘要 Disclosed is a method for producing a pot-shaped housing part (10), especially for a hub part of a hybrid drive. The housing part (10) comprises a bottom (12) and a wall (14) that extends away from the bottom (12). An external face (16) of the wall (14) extends at least nearly to an external face (18) of the bottom (12), said external face (18) of the bottom (12) facing away from a free edge (20) of the wall (14). The disclosed method encompasses the following steps: - a plate-shaped blank is provided; - said blank is braced in a workpiece holder in a radially internal zone of the blank, said radially internal zone forming the bottom of the housing part that is to be produced. A radially external zone of the blank which immediately adjoins the radially internal zone is free and forms the wall of the housing part that is to be produced. The workpiece holder has a circumferential contact surface; - the radially external zone of the blank is folded towards the contact surface and is pressed thereagainst in a shaping process in order to reduce a bending radius in the transition from an external face of the radially external zone to an external face of the radially internal zone until the external face of the radially external zone extends at least to the external face of the radially internal zone. Such a housing part is also described.
