多孔模具静液挤压镁合金棒材影响因素分析
Analysis of influencing factors on the magnesium alloy bar of the hydrostatic extrusion of the porous die
摘要
Abstract
The hydrostatic extrusion process of magnesium alloy bars with two hole,three hole and four hole die was analyzed by DEFORM-3D finite element software.The stiffness and strength of the porous die were analyzed through the MSC.MARC soft-ware.On this basis,the influence of the structure design of the four hole die on the forming process was analyzed.Combined with orthogonal test,the influence of the location of die hole,die type,calibrating strap lengths and die temperature on the extrusion force and the uniformity of flow velocity of the outlet were analyzed.The selection of a better structure design method to realize the forming of the porous die bar was analyzed.关键词
