摘　　要：采用非线性有限元软件对铜管游动芯头拉拔工艺中不同配合锥角的模具受力情况和铜管表面的受力情况进行了数值模拟和分析,推断企业目前使用的模具锥角配合是否合理,以分析当前模具锥角配合是否为影响模具寿命的主要原因。It is of great importance to conduct numerical simulation research on the drawing process with floating plug in order to improve the life of the die effectively,which appears in the drawing process. In this paper,the numerical simulation of the copper tube drawing process with floating plug was analyzed by applying nonlinear FEM software Marc ,which is widely used in the world. The distribution of vertical force and friction was obtained.
