金属压力加工本来是属于一种古老的传统手艺,完全是凭借工匠的经验。自从出现了各种压力加工机械设备后,亦仅仅是用机械力来代替笨重的体力,靠一些简单的工模具来完成一定的工艺。近年来随着现代科学技术的发展,各种学科的互相渗透,以及各种技术方法的互相借用,使金属压力加工这门比较古老的技术科学亦得到了很大的发展。许多问题的解决,以往常常是凭借经验为基础或依据。如今却陆续出现许多依靠科学的手段,包括解析和试验的方法,进行论证、评价和分析计算,从而大大加 Metal stamping originally belonged to an ancient, traditional craft, entirely based on craftsman’s experience. Since the emergence of various types of pressure-processing machinery and equipment, only mechanical force has been used to replace bulky physical strength and some simple tools have been used to accomplish certain techniques. In recent years, with the development of modern science and technology, the mutual penetration of various disciplines and the mutual borrowing of various technical methods, the relatively old technological science of metal pressure processing has also been greatly developed. The solution to many problems was often based on experience or based on experience. Nowadays, many methods rely on science, including methods of analysis and experiment, to demonstrate, evaluate, and analyze calculations one after another, which greatly increases
