Optimization of porthole extrusion die for 6063 aluminum alloy profile with thin-walled multi-cavity complex section and analysis of profile performance

In the porthole extrusion of complex profiles, the die structure plays a significant role in the formability of the profile. In this study, numerical simulation was conducted to optimize the porthole extrusion die for a complex cross-sectional profile, with the standard deviation of velocity (SDV) as the evaluation criterion. The optimization involved the introduction of pseudo-mandrels, adjustments to the shape of the 2nd-step welding chamber, and modification of the bearing height. The rationality of the optimized die structure was verified through porthole extrusion experiments, and the microstructure and mechanical properties of the profile at different locations were investigated. The results show that the optimized die effectively controlled the metal flow velocity. The actual profiles obtained from the experiments exhibited improved surface quality and avoided defects such as distortion and dimensional errors. The grain size is uniform at different positions of the profile, and the mechanical properties are comparable. The profile meets the performance requirements. This research provides guidance for the practical production of the profiles.
