加工球轴承防尘盖用凸凹模的改进

Improvement of punch and die for machining ball bearing shield

原设计的防尘盖凸凹模加工困难,废品率高,劳动强度大,质量难以保证。改为镶体结构后,加工方便,质量精度高,劳动强度低,效益相对提高。

The original punch and die for machining shield has some machining problems and cannot ensure the product quality which result the high reject rate and big labor intensity. Change the original structure of punch and die to the insert structure for solving the machining problems, so as to make machining easy, improve quality, reduce labor intensity and improve the efficiency.
