众所周知,大一些的盒形件拉深模大多采用镶口凹模结构,这样做是考虑了模具制造的经济性,但是此结构在实际使用中有时会出现这样的问题,即方盒形件的一个或两个凸缘转角处易起皱、破裂。特别是凹模镶块厚度变薄时更为明显。在工作中往往认为是设备问题,以双动压力机为例,认为是双动压力机四柱的压力不一致造成的,因而就调整设备,虽有时经
As we all know, the larger box-shaped part of the deep drawing die inlay die structure, in doing so is to consider the economical mold manufacturing, but this structure in actual use sometimes appear the problem that the square box One or two flange corner wrinkles, rupture. Especially when the thickness of the concave die insert is more obvious. Often considered in the work of the equipment to double-action presses, for example, that is double-acting presses four-column pressure caused by inconsistencies, and therefore adjust the equipment, though sometimes
