用锌合金制造冷冲模具是第二次世界大战中美国在飞机制造中为了缩短生产周期而采用的一种制模方法。随着我国工业的发展,各行业使用冲压件的比例越来越大,要求实现产品迅速更新换代,对此除了改造冲压设备,提高生产率而外,改革过去常规的模具制造方法已被广大模具工作者所重视。用熔点低的锌合金制作冷冲压模具,方法简单,制造周期短,合金材料可以反复利用,投资少,见效快,适合于单件小批生产和新产品试制,从而此项技术在国内外都得到较快的
The manufacture of cold-punched dies from zinc alloys was a modeling method used by the United States to reduce manufacturing cycles in aircraft manufacturing during the Second World War. With the development of China’s industry, the proportion of stamping parts used in various industries is increasing, requiring the rapid replacement of products. In addition to reforming stamping equipment and increasing productivity, the reform of conventional mold making methods has been widely used in molds Those who value. With low melting point zinc alloy cold stamping die, the method is simple, short manufacturing cycle, the alloy material can be reused, less investment, quick, suitable for a single small batch production and trial production of new products, which technology at home and abroad are Get faster
