Abstract:

Aiming at the manufacture of inner stator core in AC fan, two kinds of production process paths were analyzed. When the lamination process was adopted, using floating position of inner hole, self-locking performance of small slope wedge and the flap type pressure plate, the problems such as butterfly overturning and mould unloading of the iron core end face after lamination were successfully solved. It’s suitable for small batch production. When the die casting process was adopted, the rivet riveting press type or the inner sleeve tight matching type lamination traditional craft were completely changed. The better effects such as less investment, short production cycle , high quality iron core, stable size and suitable for mass production were received.

Key words: stator iron core, hard aluminum alloy, lamination, die-casting mould, casting aluminum alloy, casting
