深微孔复合挤压成形工艺的物理模拟

The physical simulation of combined extrusion about the products with deeper and thinner hole

利用两种材料 (一种为填料 )复合在一起进行挤压 ,挤压完成后将填料除去的工艺方法成形深微孔。通过物理模拟 ,探讨了挤压比、填料直径等工艺参数对深微孔成形质量的影响 。

This paper studies the forming of deeper and thinner hole in the way of combined extrusion.Through physical simulation,the extrusion ration,filler's diameter and other processing parameter's influence upon the quality of deeper and thinner hole are studied.This technique in deeper and thinner hole's forming is proved to be practical.
