Design and Optimization of Large-section Profile Die for AZ80 Alloy

Abstract

Abstract. This paper regards a kind of AZ80 magnesium alloy extrusion die as the research object to design its shape and make the systematic optimization. The results show that after optimization, the simulated extruding warpage reduced with stable dimension. By comparing the loads of dummy blocks under different die designs, the loads are close when the profile is extruded to the stable stage. After adding the diversion trench, the alloy is easier to become the desired shape through the secondary deformation.
