Heat-Stress Fields Numerical Simulation of Aluminum Profile Extrusion by Porthole Die

Abstract:

A solid geometry model of porthole die is built up by CAD . Pointing to some problems in the extruding process, such as the die fraying and the low quality of the welding during the extruding process, and the interrelated parameters, the main forming process of 7005 aluminum alloy gear pump by porthole die is simulated by using numerical analysis software DEFORM-3D with regard to heat-stress fields. Based on the results of numerical simulation, this paper gives some improvements and suggestions for optimizing the forming process.
