对双向拉延的拉深件—蓄电池盖板,在模具设计中,采用无凹模成形技术。采用整体精铸成形凸模,手工打磨的制造方法,减少机加工量。试模现场通过调整坯料形状来控制料的流动,消除裂纹。
Drawing on the two-way drawing parts - battery cover, in the mold design, using no die forming technology. Using the overall casting forming punch, hand-polished manufacturing methods to reduce the amount of machining. Trial mode by adjusting the shape of the blank to control the flow of material to eliminate cracks.
