冷冲压是汽车制造中不可缺少的一种先进工艺方法。据统计,汽车零件有60～70％是用板料冲压出来的,而且这个数字还有日益增大的趋势。因此,研完冲压技术,对于发展和提高汽车设计和制造水平有着极其重要的意义。冲压技术,由于它本身发展得比较晚,有些问题在理论上还没有得到完全的解决。特别是冲压技术在我国还比较年轻。鉴于这种状况,遵照伟大领袖毛主席“洋为中用”的教导,本期着重报导了国外有关冲压加工方面的文章和资料,供广大工农兵读者参考。
Cold stamping is an indispensable vehicle manufacturing an advanced technology methods. According to statistics, 60 to 70% of automobile parts are punched out by sheet metal, and the number is still increasing. Therefore, finishing stamping technology, for the development and improvement of automotive design and manufacturing level has a very important significance. Stamping technology, due to its late development itself, has in theory not yet been fully resolved. In particular, stamping technology in China is still relatively young. In view of this situation, in accordance with the teachings of Chairman Mao, the great leader, “learning from foreign countries,” this issue focuses on the foreign articles and materials on stamping processing for the reference of the broad masses of workers, peasants and soldiers.
