Abstract (en)

[origin: EP0770435A1] The method is used to form an axle support for a motor vehicle, through bending and hydro- forming a straight, metallic, hollow profile (2). The latter is first loaded by an internal hydraulic pressure and by an axial force on its ends (8), to form bulges (7) and to transfer profile material to the regions (6',7') which are to be deformed. Internal hydraulic pressure is then used to bend the hollow profile, and to finish its shaping process. The bulges may also be achieved by an opposing pressure which acts in the region which is to be deformed.
