三、夹模的设计1.模子结构选择。选择模子秸构的原则除前所述外,还应注意以下几点:④冲制最小尺寸的范圈(表4); ②大而复杂的零件用塔板式凹模。特删复杂的零件用组合凹模或连续模;③冲裁孔和外形相对位置要求较高的零件用复合模。冲制孔的精度较高的带孔弯曲零件应先弯外形后冲孔。2.搭边尺寸的决定。夹模搭边值此普通模具大。
Third, the mold design 1. Mold structure selection. The principle of selecting the mold structure In addition to the foregoing, should also pay attention to the following points: ④ punch the smallest size of the range (Table 4); ② large and complex parts with a tray-type die. Exceptionally complex parts with a combination of concave die or continuous mode; ③ punching holes and the relative position of the shape of the higher requirements of parts with composite die. Punched holes with high precision hole curved parts should be curved after the first hole. 2. The decision to take the edge size. Clamping mode edge value of this common mold.
