渐开线内花键冷挤成形工艺与模具

Cold Extrusion Forming Process and Die of Involute Inner Spline

此文介绍了汽车起动机单向器导筒的渐开线内花键的冷挤成形的工艺及模具.该工艺克服了传统切屑加工所带来的弊端,模具结构简单、新颖.同时该工艺还可推广应用到内斜齿轮的冷挤成形上.

In this paper,the cold extrusion forming process and die of inner spline is introduced. This spline is used for gui(?)obe of oneway clutch of auto mobile starter. The die adaped by the process has the characteristics of simple and novel strvcture ,covcrnient operating and overcomed the shortcoming of traditional process of metal cutting,and also used in the forming of inner helical gears. It has well cconomic benefit.
