在Z12—8双击整模自动冷镦机上镦制图1所示的零件,过去的加工方法是用φ11mm的六角棒料切削加工,费工费料。现在改用冷镦的方法进行生产,大大降低了原材料的消耗,提高了工作效率。经过几年的生产实践证明,产品质量稳定,装机使用多年未发现任何质量问题,现将生产过程介绍如下。 In the Z12-8 double-click on the mold automatic cold heading machine upsetting the parts shown in Figure 1, the past processing method is φ11mm hexagonal bar cutting material, labor costs materials. Now switch to cold heading method of production, greatly reducing the consumption of raw materials and improve work efficiency. After several years of production practice has proved that product quality is stable, installed for many years did not find any quality problems, the production process is as follows.
