摘　　要：在棒材开式冷挤压过程中,凹模内壁受力大小是影响凹模设计的一个很重要衡量指标。文中采用有限元软件Deform-3D,对棒材开式冷挤压过程进行数值模拟,得到凹模内壁所受应力的分布规律及各个工艺参数对凹模内壁所受应力的影响规律,并获得减小凹模内壁应力的参数优选范围,从而达到优化参数的目的。In the tubing extrusion process, the die should be reasonable designed, the die wall by the force is designed to affect the die is a very important factor. Therefore, this article uses the finite element software Deform-3D to simulate the process of open-die cold extrusion of the pipe and gets the die wall of the distribution of the stress and the impact of regulation suffered by various process parameters on the die wall stress. The die wall thickness is reduced and the stress range of.the parameter optimization is obtained to achieve the purpose of optimizing parameters.
