一、前言近年来强力旋压这种加工方法在我国得到了越来越广泛的应用。目前,不仅用它来制造航天、航空和航海的某些尖端产品,而且也用来制造常规兵器和各种民用产品。相应的机床设备也不断地涌现出来。在这种形势下,我们希望能在实践的基础上,对强力旋压的变形机理和旋压力计算等理论问题进行广泛讨论,以便深入掌握这种方法的内在规律,建立起正确的概念,找出较为准 I. Introduction In recent years, this kind of processing method of strong spinning has been applied more and more widely in our country. At present, it is not only used to make some of the most advanced products in aerospace, aviation and navigation, but also used in the manufacture of conventional weapons and various civilian products. The corresponding machine equipment also continue to emerge. Under such circumstances, we hope that on the basis of practice, we can extensively discuss such theoretical issues as the deformation mechanism of strong spinning and the calculation of spinning pressure in order to gain a better understanding of the inherent laws of this method, establish the correct concept, find More accurate
