如图1紫铜件,材料厚度1mm,该模具的主要零件设计如下:图1工件图1.模具总体设计(1)模具类型的选择由冲压工艺分析可知,采用级进冲压,所以模具类型为级进模。(2)定位方式的选择因为该模具采用的是条料,控制条料的送进方向采用导料板,无侧压装置。控制条料的送进步距采用挡料销初定距,导正销精定距。而第一件的冲压位置可由活动挡料销定距。(3)卸料,出件方式的选择
Figure 1 copper pieces, the material thickness of 1mm, the main parts of the mold design is as follows: Figure 1 workpiece Figure 1. Overall design of the mold (1) the choice of mold type Stamping process analysis shows that the use of progressive stamping, so the mold type Progressive mold. (2) the choice of positioning mode Because the mold is used strip, control strip feed direction using the guide plate, no lateral pressure device. The control of the feed strip pitch step by step with the first set of pitch, guide pin precision pitch. The first part of the stamping position can be fixed by the movable stop material pin. (3) unloading, the choice of the way out
