粗精复合小径定心渐开线花键拉刀是一种新型拉刀,它将切削余量分解,粗精拉削一次完成。 随着我国桑塔纳轿车市场的扩大,配套零部件的需求量也在增加。这种拉刀是桑塔纳轿车生产的配套工具,原从国外进口,价格昂贵,且修磨不便。目前国内尚无同类产品,我们对工件及拉床进行了测绘计算,确定拉刀型式为粗精复合小径定心渐开线,并且在拉刀上增加了中间花键定位齿及小径定位,其拉削平稳性及拉削质量得以提高,但也对拉刀的加工带来了困难。经我们多方努力,终于
Coarse Trail Calibrating Involute Spline Broach is a new type of broach that breaks down the cutting allowance and finishes roughing once. With the expansion of Santana car market in China, the demand for supporting components is also increasing. This broach is Santana car production tools, the original imported from abroad, expensive, and grinding inconvenience. At present, there is no similar product in our country. We surveyed and calculated the workpiece and the broaching machine, determined that the broach type was the roughing compound centering involute, and added the middle spline positioning tooth and the small diameter positioning on the broach. Broaching stability and broaching quality can be improved, but also the broaching process has brought difficulties. After all our efforts, finally
