The utility model relates to a manufacturing device for bent pipes, it includes roller and lower roll, the distance that should go up between roller and the lower roll can be adjusted, the lower rollincludes first lower roll and second lower roll, go up the roller set up in the top of lower roll and lie in first roller and the second lower roll between, the periphery of first lower roll and second lower roll all is equipped with the lower roll annular groove that can hold by bent pipe, the periphery of going up the roller be equipped with with the unanimous last collars connected in star of lower roll annular groove size. The device can make and buckled at the recess by the bent pipe joint, basically can not change the diameter of pipe itself. And the one set of the device can bend the return bend of a specification, multiple camber degree of buckling, not only convenient but also economy, and the practicality is extremely strong. 本实用新型涉及种弯管制作装置，其包括上辊和下辊，该上辊与下辊之间的距离能够调节，所述下辊包括第下辊和第二下辊，所述上辊设置于下辊的上方并位于第下辊和第二下辊之
