Abstract

The use of aluminum alloy has been interested in the automotive industry, because of its specific strength. And hollow extruded billet is more attractive than solid extruded billet but its forming application has to be precisely processed to satisfy the product quality. In this research, the process design of forming of control arm for the vehicle was studied by press bending process with hollow extruded billet. The middle protrusion portions and the middle cylindrical cup were processed separately according to the analysis. It was concluded that a useful sequence is to bend the side flange and the middle protrusion portions firstly, and then to form the middle cylindrical cup.
