Cold roll forming device for rectangular pipe

Abstract

The utility model provides a rectangular pipe cold roll forming device which comprises a carrier plate, a rotating shaft rotationally installed at the top of the carrier plate, a rotating plate fixed to the outer wall of the rotating shaft, a limiting block fixed to one side of the top of the rotating plate, a limiting groove formed in one side wall of the limiting block, and a movable plate detachably connected to the inner wall of the limiting groove. A lifting plate is arranged on the upper side of an inner cavity of the limiting groove, a pressing plate is connected to the bottom of the lifting plate, a threaded pipe is connected to the top of the lifting plate and movably penetrates through the top of the limiting block, and the outer wall of the threaded pipe is fixedly sleeved with a fixing ring. The wedge-shaped plate is inserted between the top of the inner cavity of the limiting block and the lifting plate, so that the wedge-shaped plate can push the lifting plate to descend, the pressing plate descends to press the surface of the rectangular pipe for limiting, after bending is finished, the abutting plate moves back, the wedge-shaped plate is separated from the limiting block, and the lifting plate is automatically reset under the action of the spring; and the formed rectangular pipe is released, and the discharging convenience of the rectangular pipe is improved.
