渐开线花键轴无屑加工研究

Study on Chipless Machining of Involute Spline Shaft

介绍了渐开线花键轴无屑加工(冷挤压工艺),对冷挤压的成形原理、工艺分析、毛坯设计、模具及重要型腔的设计进行了阐述。结果表明:渐开线花键轴采用冷挤工艺可行,产品质量好,生产效率高,产品成本低。这能为类似零件的加工工艺提供参考。

The chipless machining of involute spline shaft （cold extrusion process） was introduced. The forming principle of cold extrusion, process analysis, blank design, die and important cavity design were discussed. The results show that： the cold extrusion process for involute spline shaft is feasible. The product quality is good, the production efficiency is high, and the product cost is low. This can provide reference for similar parts processing technology.
