Numerical Simulation and Die Optimization Design of Extrusion Process for a Complex Hollow Aluminum Alloy Multi-Hole Die

Abstract:

The steady state extrusion process of a complex, multi-hole aluminum extrusion die was simulated using the Arbitrary Lagrangian Eulerian (ALE) algorithm. According to the numerical simulation results and the extrusion experiment, a combined method of modifying the portholes, double-step welding chamber and adjusting bearings were proposed for qualified profiles. In this study, the influence of the shape of portholes and double-step welding chamber on the material flow velocity distribution at the outlet were emphatically analysed, and some reference value for the designing and modifying of multi-hole die is existed basing on the method.
