ASH-G冷镦机模具的设计改进

Design Improvement of Dies for ASH-G Cold Header

通过提高模具的硬度和韧性，修正球窝形状、改进模具球窝车加工工艺、提高球窝尺寸精度和降低粗糙度值以及压缩球窝直径、加大球窝深度等方法，使ASH－G冷镦机的钢球毛坯冲压模具的寿命明显提高，毛坯的余量减少，尺寸稳定，大大降低生产成本。附图4幅．

Using such methods as raising hardness and toughness of die, modify-ins ball socket shape, improving turnery of die ball socket, raising ball socket dimensionalprecision, decreasing ball socket surface roughness, reducing ball socket diameter and in-creasing ball socket depth, etc.can obviously raise ball blank heading die life of ASH-GCold Header, decrease margin of blank, stabilhe dimension and save on production costgreatly.
