影响冲模寿命的因素很多,我们认为模具形体间的相对位置的同心和相对稳定,是主要原因之一。一付冲模很少是因为自然磨损而报废,往往都是因为模具相对稳定性差刃口被啃,返复修磨而报废。而浮动式模具结构它不受机床精度的限制(当然垂直平行度不能太差),不受瞬间冲击力的影响,行程小导柱精度易于保证,只要模具制作精度高 Many factors affect the life of die, die shape we think that the relative position between the concentric and relatively stable, is one of the main reasons. A pair of die is rarely scrapped because of natural wear and tear, often because of the relative stability of the die poor edge is chewing, grinding and scrapped and scrapped. The floating mold structure it is not limited by the accuracy of the machine (of course, the vertical parallelism can not be too bad), free from the impact of instant impact, easy to ensure the accuracy of small guide column, as long as the high precision molds
