Abstract：

In this paper, an available cold\|extrusion process to shape the plane\|chair\|clasp cylinder was determined by studying its shape characteristics and fabricating difficulities. We also made a set of cold\|extrusion die and manufactured qualified parts. The shaping course of the parts was demonstrated and analysed;And the extrusion force to different transfiguration degree was recorded to draw the continuous extrusion force curve during the cold-extrusion course. We also observed the part section's metal fibre structure in the direction of extrusion force and gave a reasonable explanation to the flow line's distribution.
