用多辊轧头沿轴向滚轧花键轴,毛坯不需加热,与铣切法比较可以显著地提高成型工序的生产率,降低金属耗量,改善产品质量及其使用性能,滚轧表面的光洁度相当于▽_7——▽_(?)。加工简图见图1。毛坯通过能在轴上自由旋转的轧辊(轧辊数等于滚轧的槽数)而被轧出,轧辊呈星形配置在轧头的座体内。这种方法可加工平行于轴的三角形花键、渐开线花键、矩形花键。对于不同的花键要采用不同的轧头。此法适于大批生产或成批生产。据初步
Rolling the spline shaft axially with a multi-roll head eliminates the need for heating the blank and significantly improves the productivity of the forming process compared with the milling method, reduces the metal consumption, improves the product quality and its serviceability, The finish is equivalent to ▽ _7-- ▽ _ (?). Processing diagram shown in Figure 1. The blank is rolled out by a roll that can rotate freely on the shaft (the number of rolls is equal to the number of rolls). The roll is arranged in a star shape in the seat of the rolling head. This method can be processed parallel to the axis of the triangular spline, involute splines, rectangular splines. For different splines to adopt a different rolling head. This method is suitable for mass production or mass production. It is preliminary
