Abstract：

According to the analysis of the extrusion process of the flexible aluminum pipe,the parameters of flexible pipe,such as wall thickness and the length diameter ratio of an eyelet of a cup-shaped components with steps in inside-diameter are gained which are appropriate to the cold extruding forming.The blank dimension,the softening treatment before formation and the way of mat forming treatment,and the lubing in extrusion process are determined and the structure of the extrusion die is designed.Also the innovative design,for example,the use of collapsible male die in the structure of working part,the use of partly arbor punch and partly assistance guidance and fastening of the punch shank and self-alignment are made to meet the need of the process.
