大双击冷镦机上生产十字槽螺钉的实践经验告诉我们,冷镦材料的机械性能、模具质量、操作技术水平、设备精度和初镦型腔,是能否正常生产的主要因素。而初镦型腔的几何形状是否合理,是能否生产的关键。 根据我们大批量生产的情况,这里介绍初镦型腔的设计,供参考并与大家探讨。 在冷镦材料性能、模具质量、冷镦线材 Double-click on the cold forging machine production of cross-recessed screw on the practical experience tells us that the mechanical properties of cold heading materials, mold quality, operating skills, equipment accuracy and initial heading cavity, is the main factor in the normal production. The initial heading cavity geometry is reasonable, is the key to whether the production. According to our mass production situation, here is the design of the early heading cavity for reference and to discuss with you. In the cold heading material performance, mold quality, cold heading wire
