摘要
轴承滚子采用Z31-25冷镦机锻压加工毛坯。在分析冷镦机切料方式和切料原理的基础上,通过改进切料刀片,使滚子毛坯重量公差和断面塌角更小、断面更平整、质量更好。
Z31-25 cold forging machine now was used to work the blank of bearing roller. The cutting blade was improved on the basis of analyzing cutting method and principle of cold forging machine, so that the weight tolerance and sunk corner of cross section of roller blank were both improved. The evenness and quality of cross section were guaranteed.
