高强度密封钢丝生产控制

Production control of high strength sealing steel wire

探讨130 mm密封钢丝绳用高强度Z6-4型密封钢丝生产工艺和模具设计,通过分析改进了旋转模盒空心轴的设计方案,总结出保证产品力学性能的注意事项,从原材料、操作人员、异型模具和长度精度控制4个方面对产品生产质量控制要点进行分析。密封钢丝绳质量控制关键点在钢丝生产质量控制,密封钢丝质量控制需高度重视工艺优化设计,拉丝设备工装保证,模具材质及尺寸改进以及操作工人的技能培训工作。经过改进,生产的密封钢丝外形符合标准规定,能够满足钢丝绳尺寸精度要求,合绳后钢丝绳表面良好,强度、弯曲、扭转性能符合国家标准规定。

Discussion on production process and mould design of high strength Z6-4 sealing steel wire for diameter 130 mm sealing wire rope. Through analysis,the design scheme of the hollow shaft of the rotary mould box is improved,and the matters needing attention for ensuring the mechanical properties of the product are summarized. The key points of product quality control are analyzed from 4 aspects： raw materials,operators,special mould and length accuracy control. The key point of quality control for sealing wire rope is quality control of steel wire production. The quality control of the sealing steel wire needs to be highly valued in the process optimization design,the guarantee of the wire drawing equipment,the improvement of the material and the size of the mould and the skill training of the operating workers. After improvement,the shape of the sealing steel wire produced is in accordance with the standard requirements. It can meet the requirements of the wire rope size accuracy. The surface of the wire rope is good,the strength,bending and torsional performance are in accordance with the national standard.
