铜排通风孔冲孔模设计

Design of Piercing Die for the Copper Vent

介绍了一种新型结构的铜排通风孔冲孔模,在冲制通风孔的同时压制出一个倒角,使得冲裁产生的毛刺消失,节省了后面的铣削工序和人工打毛刺,明显地提高了加工效率和线圈质量。

This paper introduces a kind of new structure piercing die for the copper vent, at the time of piercing out a chamfering, makes the burr generated disappear, save the milling back and artificial deburring, obviously improves the machining efficiency and the coil quality.
