我厂定转子冲片复式模的凸凹模加工方法有二种: 1.凸模成型磨削,凹模采用拼块成型磨削,然后热套。 2.凸模成型磨削,以凸模作电极电加工凹模。我厂的成型磨削是在平面及成型磨床上进行的。在成型磨床加工凸模圆弧“R”及凹模拼块大端圆弧面。在平面磨床利用正弦规,使磁力吸盘搬动角度,用“角度工具”和“圆弧工具”修正砂轮方法,完成凸模及拼块凹模的成型磨削。
There are two kinds of processing methods for the punch and die of the compound die of the rotor punching piece in our factory: 1. Forming and grinding of the punch and die, the concave die is shaped and ground by the block, then the heat sleeve. 2 punch molding grinding, punch as the electrode processing die. I plant the molding grinding is carried out in the plane and forming grinder. In the molding grinder processing punch circular arc “R” and concave block big arc surface. In the surface grinder use of sine rules, the magnetic suction cup moving angle, with “angle tool” and “arc tool” to amend the grinding wheel method to complete the punch and die forming die grinding.
