DESIGN AND MANUFACTURE OF DIE SET WITH FLANGED GEAR

介绍了法兰盘上有三个孔的粉末冶金齿轮的压制方法,模具结构,阴模设计及制造工艺,还介绍了加工阴模的电极材料及其设计、制造方法。

The compacting method, the die set structure and the design and manufacturing process of cavity die for P/M gear with three-hole flange have been introduced. By using cavity die for P/M gear with three-hole flange made by the process combining wire cutting and electric spark, high precision gear can be produced.The required size and pitch of three holes can easily be quaranteed. In case that module is below I and the thickness of cavity die is up to 25mm, both finish and rough parts of electrode can be eiectrically machined from one piece of raw material, thus the precision of cavity die can be easily guaranteed.
