我厂生产的连挡中轴,一直是采用φ22.5光圆钢在六角车床上分五个工步切削加工的,劳动强度高,生产效率低,材料浪费很大,远远不能满足生产和出口的需要。最近以来,我厂响应党的号召,大搞技术革新,通过了一系列的工艺试验,连挡中轴在普通压力机上进行冷镦成形,获得成功。—、冷镦工艺目前我厂生产的中轴是由:落料(坯料准备)→退火→车圆头→磷化→皂化→冷镦六个工序组成的。1.坯料准备:中轴的钢料采用含碳量在
I plant the production of the block axis, has been using φ22.5 light round steel lathe in five steps of cutting, high labor intensity, low production efficiency, material waste, far can not meet the production and Need for export. Recently, our factory responded to the call of the party, engaged in technological innovation, passed a series of technological tests, and succeeded in cold forging forming on the normal press. -, cold heading process At present, I produced the shaft is: blanking (blank preparation) → annealing → car round head → phosphating → saponification → cold heading of six processes. 1. Blank preparation: The shaft of the carbon content in steel
