圆柱滚子轴承保持架冲孔凸模加工工艺改进的探讨

Process improvement for punch of punching cage pocket of cylindrical roller bearing

针对保持架冲孔模凸模加工难度大,加工精度不易保证,容易产生废品这一问题,将凸模结构由一体改为二体,加工工艺由冲模加工改为线切割机床加工。经过改进,降低了加工难度,减小了废品率,提高了生产效率,节约了生产成本。

Aim at the problem that it is hard to process,not easy to ensure the processing accuracy,and easy to scrap for punch of punching cage pocket,the punch structure is divided into two body,and processing method is changed from punching into linear cutting.Through improvement,the process becomes easy and the scrapping rate is reduced so as to improve the production efficiency and save production cost.
