铆螺钢丝镦头开裂原因分析

Analyzing Why the Cold Heading Wire Breaks When Being Punched

铆螺钢丝在生产螺钉的过程中镦头开裂问题一直困扰着钢丝生产厂家。从化学成分及成分偏析、盘条原始质量、球化退火组织、成品压缩率４个方面着手，对铆螺钢丝镦头开裂原因进行分析，着重探讨盘条原始质量和球化组织的影响，提出减少开裂的措施。

Cold heading wire production factories are always puzzled by a difficult question that the wire often breaks when being punched The reasons are analyzed from such four aspects as chemical composition,composition segregation and quality of wire rod,spheroidal annealed morphologies of steel wire,area reduction of finished product The effects of the quality of wire rod and the spheroidal morphologies of wire on it are emphatically approached Some measures for reducing break are put forward
