摘　　要：O成形既是UOE方法制造直缝焊管焊接前的最后一道成形工序,也是考核制品成形质量的重要环节,其成形质量将直接影响到机械扩径后钢管制品的成形质量。该文就O成形工艺参数和来料质量,对成形质量的影响规律进行实验研究,分析了弯边半径、弯边弧长和压缩率等参数对O成形焊管成形质量的影响,以及压缩率与成形载荷之间的关系。O-forming is the last forming process before straight welding pipe welded by UOE, while it is main process which check how the product quality is. Forming quality of pipe through mechanical expanding is effected directly by the process. In this paper the influence regularity on forming quality by O-forming technological parameters and stock quality was experimental researched, radius of flange, arc length of flange and compressibility whose impact on O-forming quality and the relationship between compressibility and forming load were analyzed.
