Method of making an axle element for a motor vehicle, and shaping die for carrying out the method

摘要

In a method of making an axle element for a motor vehicle, a rod-shaped semi-finished product of aluminum is use used as starting material and heated to a desired shaping temperature. A first end of the semi-finished product is upset in a cavity of a shaping die by means of a first punch. Subsequently, the other end of the semi-finished product is compressed in the cavity by a second punch, whereby compressed material is forced into a branch of the cavity to form a pre-forge part with a leg portion. The pre-forge part is then forged into a finished axle element, e.g. a swivel bearing.
