Research on the Influence of Die Shape in Complex Extrusion of Multi Billets

Abstract:

Multi-billet extrusion has been developed for a novel process in manufacturing of shapes with complex cross-section, for example a side-door impact beam for automobile. And furthermore, very wide shapes for roofs of railroad vehicles may be able to be manufactured. In this paper, fundamental experiment carried out by using modeling material and knowledge about bonding of some separated parts was obtained. It is clear that a unification angle is important for bonding intensity. The unification angle was adjusted by flow guides. It is success to manufacture a round pipe with inner liv.
