抛光与喷砂工序对汽车刹车片加工工艺影响试验研究
|
摘要
在分析盘式制动器刹车片制造工艺的基础上,针对刹车片的表面处理工序抛光、喷砂的作用进行试验验证。试验结果表明:抛光、喷砂两种工序都对刹车片表面质量有重要影响,其中抛光能解决钢背冲压过程中出现的毛边、毛刺以及热压机上压制过程中出现的溢料问题;喷砂能清理钢背表面的锈迹、油污,对喷塑材料有固定作用。
Based on the analysis of the manufacturing process of disc brake pads,the effects of the polishing and sandblasting to the surface of the brake pads were tested. The test results show that polishing and sandblasting process have important influences on the surface quality of the brake block. The polishing process can solve the problem of burrs in the process of stamping steel back and the problem of overflow in pressing process of hot press. Sandblasting can clean rust,oil on the steel back surface and it can fix the plastic materials.
