摘要
根据轴向应力对棒料剪断方式及其断口形状的影响,设计了对螺帽锻造所用热轧棒料能进行精密剪切下料的新型结构的径向支持下料模具.采取增加下六角冲头与凹模的配合长度及配合精度的导向方法,设计了在80吨非标压力机上锻带孔螺帽的成形模具.给出了两种模具的试验结果.
The die for the blanking under the radial clamp of nuts for 1C engine is designed based on The effect of radial stress on the shearing method for bars and the fracture shape. The (lie of the nuts for the forging holes formed in the non-standard pressing machine of 80 ton is also designed. And the testing results of both dies are given.
