摘要
对国内外不同企业、不同结构压实单层股抗旋转钢丝绳的标识与压实方法进行研究,分析认为在圆股挤压成型、整体模拉、辊拉、锻打等压实钢丝绳生产方法中,锻打法最为合理。介绍不同压实方法的优缺点。锻打法的优点:可以实施大的压缩率;对股捻制质量要求相对较松,锻后钢丝绳外观质量好;捻制内应力可以得到充分消除,锻后钢丝绳平直性好、柔软;对绳股结构无要求。但锻打法存在设备投资大、效率低等缺点。
To research the marking and compacting methods of compacted single layer strand rotation resistance wire rope with different structure made by domestic and abroad enterprises.It is considered by analysis that the swaging method is the most reasonable in production methods of round strand extruding,whole die drawing,roller drawing,swaging.The advantages and disadvantages of different compacting methods are introduced.The advantages of swaging are： can implement big compressibility;strands laying quality need not strict and the appearance quality of wire rope is good after swaged;laying inner stress of wire rope can be fully eliminated,so the swaged wire ropes have good straightness and is soft;no requirement for strand and rope structure.But swaging method exists disadvantages such as much investment for equipment and lower efficiency.
