在小批生产中,工件上的孔有时采用单冲孔,所以冲孔模一般设计成为通用的可换结构,特别是大型冲模中的一些小凸模多属易损件。为了使模具便于维修,也常把这种小凸模设计成这类结构。从而节省了换模时间和节约了模具。下面是几种简单的快换凸模结构: 1.螺丁固定式。在凸摸柄上开10°～15°的斜槽,用螺下固定,更换时只需拧松螺丁,凸模即可取出。这种结构,多用于
In small batch production, the holes on the workpiece are sometimes single punched, so punching dies are generally designed to be versatile replaceable structures, especially some small punches in a large die. In order to make the mold easy to maintain, this small punch is often designed into such a structure. This saves mold change time and saves the mold. Here are some simple quick punch punch structure: 1. Spiral fixed. In the convex handle on the open 10 ° ~ 15 ° of the chute, fixed with a screw, screwdriver just loosen the replacement, the punch can be removed. This structure, used for more
