根据某型号狄舍尔 穿孔机的实际尺寸（重要几何参数见表 2），用造型软 件 Pro/E 建立三维有限元模型后导入到 DEFORM-3D 中。由棒料尺寸和毛管尺寸确定空间位置关系后，所 建立的三维模型如图 1 所示。

According to the actual size of a certain model of Discher puncher (important geometric parameters are shown in Table 2), use the modeling software Pro/E to establish a three-dimensional finite element model and import it into DEFORM-3D. After determining the spatial position relationship by the bar size and the capillary size, the established three-dimensional model is shown in Figure 1.
