Abstract：

Based on the diversion extrusion die of half-hollow aluminum profile, the extrusion process was simulated and the technological parameters of extrusion process were optimized using the finite element analysis software HyperXtrude. The orthogonal test was applied to analyze the influential regularities of technological parameters such as extrusion speed, extrusion cylinder temperature, billet temperature and die temperature etc. on extrusion flow uniformity. The results show that the influential order of technological parameters affecting the extrusion uniformity according to the standard speed deviation SDV is extrusion speed > extrusion cylinder temperature > die temperature > billet temperature. The optimized technological parameters are billet temperature 490 ℃, die temperature 480 ℃, extrusion cylinder temperature 420 ℃ and extrusion speed 1.5 mm·s-1. According to the above technological parameters, extrusion die was designed and extrusion experiment was carried on. As a result, qualified extrusion uniformity sample was obtained.
