摘　　要：为了有效提升螺旋焊管成型过程控制质量,分析了钢带“镰刀弯”对成型入口钢带递送线位置的影响因素,通过实例分析了现有后摆式焊管机组生产中表现出的钢带跑偏问题,并对钢带边缘定位和中心定位方式的机组纠偏能力进行了对比。分析表明,后摆式机组现有工艺存在适应性较差的问题,提出了后摆式螺旋焊管机组递送线中心定位改造方案。改进结果表明,后摆式螺旋焊管机组的区段性递送线定位方式改造是焊管成型系统工艺能力提升的有效方法。In order to effectively improving the quality of spiral welded pipe forming process control,the influence factors of steel strip"camber"on forming entrance strip delivery line are analyzed,the deviation problem of the steel strip in the production of the existing backswing welded pipe unit is analyzed through examples,and the deviation correction ability of the units with edge positioning and center positioning are compared.The analysis shows that the existing technology of backswing unit has poor adaptability,and the center positioning reform scheme of backswing spiral welded pipe unit delivery line is put forward.The improvement results show that the transformation of section delivery line positioning mode of backswing spiral welded pipe unit is an effective way to improve the process capacity of welded pipe forming system.
