摘　　要：为保证3PE防腐钢管管端涂层的车削质量,通过对车削质量的影响因素进行分析,并提出相应的控制措施。结果表明,在车削过程中,刀具磨损、刀具安装、起刀位置、气缸压力和钢管直度、圆度是影响管端涂层车削质量的主要因素,建议通过控制修磨刀具夹角、选择最佳起刀位置、合理调节气缸压力及增加管端辅助压辊装置等措施,提高管端涂层车削质量的稳定性。改进后的工艺可应用于Φ508 mm~Φ1536 mm规格3PE、3PP防腐钢管管端涂层的车削,能够满足生产需求。In order to ensure the turning quality of 3PE anti-corrosion pipe end coating turning process,by analyzing the influencing factors on the turning quality,the corresponding control measures are put forward.The research shows that in the turning process,tool grinding,tool installation,tool starting position,cylinder air pressure,straightness and out of roundness of steel pipe are the main factors affecting the turning quality of pipe end coating.It is suggested that the stability of pipe end coating turning quality can be improved by controlling the included angle of grinding tools,selecting the best tool starting position,reasonably adjusting the cylinder pressure and increasing the auxiliary roller device at the pipe end.The improved process is applied toΦ508 mm~Φ1536 mm 3PE and 3PP anti-corrosion pipe end coating turning can meet the production demand.
