细长传动轴两端花键冷挤压实验

Experiment of cold extrusion for forming two involute spline ends of slim drive shaft

细长传动轴两端花键头进行了冷挤压加工分析与工艺实验。针对工件特点,在工艺实验过程中采用了高频加热退火软化、加冷挤压油表面润滑和二次分级挤压等工艺方法,取得了良好的效果。

An analysis on the cold extrusion process and a technological experiment were made for the two spline ends of a slim drive shaft. Some technique were used in the experiment in view of the characteristics of the component, which covers heatronic annealing treatment, surface lubrication with add of cold extrusion oil and two-step sequential extrusion, etc.
