图1所示零件,是刹车泵中一个零件的展开图,用常见的凸凹模难于完成。通过试验,最后我们用片状带齿凸模,条沟状凹模,采用特殊侧刃切边定位的连续形式,解决了问题。生产效率高,制件质量好。 图2为该模具示意图。仅示出凹模及凹模B向;凸模、侧刃组合及其在凸模夹中的固定形式。凸模夹用螺钉、销子通过垫板固定于上模板,上模板尚带有模柄,安装于冲 The part shown in Figure 1 is an expanded view of a part of a brake pump that is difficult to accomplish with the common punch and die. Through the test, finally we solve the problem by using the flaky toothed punch, the groove-shaped concave die, the continuous form of the special side edge cutting edge positioning. High production efficiency, good quality parts. Figure 2 is a schematic diagram of the mold. Only the B-direction of the die and die is shown; the punch, the side-blade combination and its fixed form in the punch holder. Punch clamp with screws, pin fixed to the template through the pad, the template is still with a mold handle, installed in the red
