为了进一步提高轴承环的材料利用率,瓦房店轴承厂近年来试验成功了中温辗压整形新工艺,效果良好。工艺流程为:园棒料——加热——切断——镦饼——冲盲孔——冲穿平端面——第一次初辗——退火——中
In order to further improve the material utilization of the bearing ring, Wafangdian Bearing Factory in recent years successfully tested in the temperature rolling plastic new technology, the effect is good. Process: Garden bar - heating - cut off - forging cake - punching blind hole - punching through the flat surface - the first roller - annealing - in
