【Abstract】 Generally, the technique of extruding the long conical pipe whose relative height is 5~12 is very hard. In this paper, we study the technique of cold extruding forming,and produced all kinds of the long conical pipe in that way. And we study the theory of the technique of cold extruding forming,the condition of the technique and the parameter of designing the cold extruding forming die. This technique is very simple, and the utilization ratio of material is very high.更多还原
