冲裁、引伸、弯曲、冷挤等凸凹模之间的间隙对脱料力、剪压力、加工质量、模具使用寿命等都有明显影响。一般在模具设计和模具制造中,通过规定凸模、凹模等零件的尺寸精度,使模具得到合理的间隙尺寸。要保证凸模和凹模之间的间隙均匀,则还要注意凸模和凹模的正确装配。 Blanking, extension, bending, cold extrusion and other punch between the gap between the de-feeding force, shear pressure, processing quality, mold life and so have a significant impact. Generally in the mold design and mold manufacturing, through the provisions of punch, die and other parts of the dimensional accuracy, the mold to get a reasonable gap size. To ensure that the gap between the punch and die evenly, then also pay attention to the correct assembly punch and die.
