在学习无产阶级专政理论的高潮中,我车间广大职工热烈响应党的号召,抓革命,促生产,开展了轰轰烈烈的技术革新活动,异形簧卡弯曲成形模的革新就是其中的一项。异形簧卡是用φ1.2毫米的70号弹簧钢丝制成的安全继电器上的零件(图1),形状比较复杂,过去分三道工序成形,由于质量不能保证,最后还要手工整形。模具革新后,只需一次成形就能满足图纸要求。
At the height of studying the theory of proletarian dictatorship, the broad masses of workers and staff in our workshop enthusiastically responded to the party’s call, took revolution and promoted production, and carried out vigorous technological innovations. The innovation of the bending mold of heteromorphic spring cards is one of them. Abnormal shape spring card is φ1.2 mm spring steel 70 made of safety relay parts (Figure 1), the shape is more complex, in the past three processes forming, because the quality can not be guaranteed, the final manual shaping. After the mold innovation, just one time to be able to meet the drawings requirements.
