一、前言爆炸成型是近几年新发展起来的金属冷加工成型新工艺。它在石油,化工部门较早开始试用,目前已成功地在全国范围内推广使用。我处是从1972年开始实践的,由于它有许多优点,近几年来几乎成为我处容器封头成型加工的主要方法。此工艺的实现,大大地提高了劳动生产率,减轻了劳动强度,节约了原材料和劳动力,并解决了大型压力机缺乏的困难。另外爆炸成型只需一个模具,甚至不用模具。因而降低了模具制造的成本。并且由于成型是瞬时的冷加工,因此所得产品表面光洁度很好。同时只要工艺掌握正确,产品型状精度亦可达到较高的要求。这项工艺的缺点是在无整形爆炸成型时,直边部常有皱褶(尤其是薄钢板爆 First, the foreword Explosion molding is the newly developed metal cold forming process in recent years. It has been piloted earlier in the petroleum and chemical sectors and has been successfully promoted across the country. Our office has been practicing since 1972. Because of its many advantages, it has become almost the main method for forming the container head in recent years. The realization of this process has greatly increased labor productivity, reduced labor intensity, saved raw materials and labor, and solved the difficulties of lack of large presses. Another explosion molding only a mold, not even mold. Thus reducing the cost of mold manufacturing. And because the molding is instantaneous cold work, the resulting product surface finish is good. At the same time as long as the craft mastered correctly, the product shape accuracy can reach higher requirements. The disadvantage of this process is that in the non-plastic explosion molding, the straight edge wrinkles (especially the thin steel plate burst
