管材开式冷挤压中挤压力的数值模拟

Numerical Simulation Rearch on Extrusioning Force of Open-die Cold Extrusion of Tubes

在管材挤压过程中,挤压力对工件成形起到了十分关键的作用,采用有限元软件Deform—3D进行模拟分析,探讨了挤压成形过程中各个参数对挤压力的影响程度,从而达到优化参数的目的。

In the tubing extrusion process,the extrusion pressure plays important role in forming the work piec.By using finite element software Deform-3D to carry on the simulation analysis,the paper has discussed the influence of each parameter to the extrusion pressure in the press forming process,so as to achieve the goal of optimizing parameter.
