摘　　要：在采用上限法的流函数模式对常规厚壁管件冷挤压成形建立理想模型的基础上，定性地分析了常规开式冷挤压成形规律。然后用实验研究的方法研究了厚壁管件上小尺寸深锥孔的成形加工及预测其变形后的工艺尺寸。By means of flow function model of upper bound method,an ideal model for extrusion in ordinary thickwall tube is founded,followed by qualitative analysis of the forming principles of ordinary thick-wall tube.Then,based on experimental research,the forming technology of small deep cone hole in thickwall tube and prediction of the technological size are studied.The ideal model for open type extrusion in ordinary thickwall tube is modified.
