解放牌汽车中间轴的毛坯有九段台阶,并且公差余量都比较小,一般是用模锻成型的,这就需要昂贵的模锻设备和锻模,对于中小工厂是有困难的。我们在生产实践中经过反复摸索,终于在750公斤空气锤上两火锻出了合格的锻件。锻件的技术要求:1.锻造圆角R3~5,锻造斜度5°;2.锻
Jiefang brand truck’s intermediate shaft blank has nine steps, and the tolerances are relatively small, is generally used forging molding, which requires expensive forging equipment and forging die, for small and medium-sized factories is difficult. After repeated exploration in our production practices, we finally made two forged forgings on the 750 kg air hammer. Forging the technical requirements: 1. Forging fillet R3 ~ 5, forging slope of 5 °; 2. Forging
