模锻件折纹在锻造生产中时有发生,有些折纹用肉眼可以看到,有些则需经酸洗或探伤后才能发现。如果折纹在最后工序出现,则会造成废品及经济上的损失。我们厂生产的模锻件以圆形件为主(齿轮和圈环),锻件折纹大部分产生在从轮辐到轮缘的交界处或齿轮的尾部凸台上,尤其是孔径大而厚度小的锻件很容易产生,如X52K立式升 Forging parts forging in the production of the fold from time to time, some fold with the naked eye can be seen, while others need to be pickling or testing before they can be found. If the crease appears in the final process, it will cause waste and economic losses. Forgings produced by our factory are mainly round parts (gear and ring). Most of the forging crease is produced at the junction from the spokes to the rim or on the boss of the tail of the gear, especially the large diameter and small thickness Forgings are easy to produce, such as X52K vertical rise
