铝合金型材挤压模优化设计

Optimal Design of Aluminum Alloy Profile Extrusion Die

通过对铝合金型材挤压模具造型,并采用软件Hyper Xtrude对其挤压成形过程进行了模拟。通过对型材截面形状特征与对原模具的模拟结果的分析,以模拟的挤压参数的精确预测为依据,结合设计经验,对模具进行了优化设计。同时,为了获得更好的型材质量与更高的生产效率,探究多级模具焊合室对型材质量的影响。通过对各方案的模拟,最终得出挤压速度更均匀、型材质量更好、更适合于生产的模具。

Through modelling of aluminum profile extrusion die,the extrusion forming process was simulated by adopting the software HyperXtrude. Through the analysis of profile section shape characteristics and the simulation results of the original die, taking the accurate prediction of extrusion parameters of simulation as the basis, and combining with design experience, the optimized design of the die was carried out. At the same time, in order to obtain better profile material quality and higher production efficiency, the effects of multi-step die welding chamber on the profile quality were explored. Through the simulation of each scheme, the more uniform extrusion speed, better quality profiles and more suitable production die were obtained.
