微型轴承冠形保持架压球窝模具改进设计

摘要

In order to solve the problems in the processing of ball -and -fitting molds of the original cage,the im-provement of the die design is carried out from the die precision,the guide device,the filling method and so on.After improvement,the stamping pass qualified rate is increased from 50% to 95%,with processing efficiency increased by 3 times.%分析微型轴承冲压冠形保持架压球窝的加工难点,针对原保持架压球窝模具加工中存在的问题,从凹模精度、导向装置、填球方式等方面进行了模具改进设计,改进模具后保持架冲压合格率由50%提高到95%,加工效率提高3倍.
