| Abstract: | The cold extrusion shaping principle?extrusion process and die structure feature of involute spline are introduced in this paper,and describe the structure design of involute profile spline mould core.Contrast to conventional generating process,the involute profile spline of cold extrusion shaping has the advantages of higher profile intension?higher profile precision?higher material utilization ratio and higher production efficiency etc.Through the practical indication of high batch volume production,applying cold extrusion shaping technology to produce the involute profile splined shaft has a marked eccnomic benefit. |
