一、前言爆炸成形是一种利用短时,强烈的爆炸压力使一金属平板成形的一种方法。所需的产品形状一般是由阴模决定的。本文介绍既不需要阴模,也不需要阳模而将一金属平板成形为一对称回转体的技术的研究成果,主要用于成形直径为大于6英尺的金属壳体的无模技术,没有尺寸限制。通过改变该技术中的一些主要参数,就可以较经济地成形各种形状的金属壳体。 I. INTRODUCTION Explosion forming is a method of forming a metal plate by using short-time and intense explosion pressure. The desired product shape is generally determined by the negative. This paper presents the findings of a technique that does not require a female mold and does not require a male mold to form a metal flat plate into a symmetrical rotary body. It is primarily used in die-less techniques for forming metal shells larger than 6 feet in diameter without size limit. By changing some of the main parameters of this technology, it is possible to shape metal housings of various shapes more economically.
