The Influence of the Punch Shape on the Socket Spanner Extrusion Process

Abstract:

Punch is a key component in Socket-Spanner extrusion and its shape influence the extrusion molding heavily. Using the FEA software DEFORM, the paper simulated the extrusion process of three kinds of upper and lower extrusion punch combinations which have different shape and studied the influences of the punch shape on metal flowing, Z direction punch load and equivalent stress. By contrasting the simulation data, the best punch shape was chosen. Our results could provide theory evidence for optimization design of Socket-Spanner extrusion punch. It was shown that the tapered bottom punch is the most suitable shape for the socket-spanner extrusion than the flat tapered and the flat one.
