芯棒
mandrel

  x inbang芯棒(mandrel)生产无缝管时插进管体内部同乳辐等构成环形孔型使管材成形用的工具。连续札管机轧管、管材针轧延伸、周期式轧管机乳管、顶管和管材冷乳冷拔时都要使用芯棒。 芯棒是一根很长的圆棒和顶头一样在变形区内参与管材的变形,不同的是针乳时芯棒在管内随着管材边旋转边做轴向运动;纵札(连轧管、周期式轧管、顶管)时芯棒不旋转但也随管做轴向运动。 在浮动芯棒和限动芯棒连轧管机上(见连续乳管机札管),芯棒是重要的工具,它们除了要求用高强度和高耐磨性的材质制做外,还要求很高的表面质量,如车削后要经研磨和热处理。浮动芯棒很长(达30m)很重(达12t)。限动芯棒的长度稍短,但对材质要求更高。顶管对使用的芯棒应能承受很大的顶推力。周期式轧管机的芯律工作时受热时间长。斜轧延伸机的芯棒有拉力芯棒、浮动芯棒、限动芯棒和回退式芯棒等。 拉力芯棒是工作时轴向运动速度大于管子轴向运动速度的芯棒(见管材针轧延伸),芯棒对管子内表面_施加拉力。回退式芯棒是芯棒轴向运动方向与管子轴向运动方向相反,施加后拉力的芯棒。斜轧延伸机对芯棒的要求比纵轧延伸机的要低。 (李连诗)
