Abstract

This paper reports on an experimental and finite-element analysis of a backward extrusion process of 7075 Al alloy. The influence of punch speed and billet temperatures on the backward extrusion process was investigated. DEFORM-3D software was used for finite-element simulations. A backward extrusion die was designed and manufactured for the purpose of experimental research. From simulation, the forming load and stress/strain distribution of the billet were obtained. The simulation results show that the effective stress/strain distributions are inhomogeneous in the deformed billet. Finite-element method has been used successfully to predict the backward extrusion load, indicating the good accuracy of the simulation results. In this study, the effects of the different temperatures and punch speeds on the effective stress/strain distribution and forming load during forming process were investigated.
