Problems solved by technology

[0002] The pressure equalizing ring is an annular hollow tube, which is made by manual beating or welding of two semicircular hollow tubes. The semicircular hollow tube is bent by a straight tube through a pipe bender. The existing pipe bender is There is a defect that the hollow tube is seriously deformed during the tube, and the bent part is stretched, resulting in thinning of the tube wall and shortening the life of the pressure equalizing ring

Abstract

The invention provides a pipe bending machine and relates to a metal pipe bending device. The pipe bending machine comprises a machine frame, an anti-shriveling plug and a clamp, wherein a lower supporting seat is arranged under the machine frame, an upper supporting seat is arranged above the lower supporting seat, a pipe bending wheel is arranged above one side of the machine frame, an arc-shaped groove is formed in the periphery of the pipe bending wheel, the pipe bending wheel is connected with a spindle, and the spindle is supported in the upper supporting seat and the lower supporting seat. The spindle is connected with a speed reducing device, and the speed reducing device is connected with a power device. A vertically-arranged rotating shaft is connected above the other side of the machine frame, a connecting rod is connected onto the rotating shaft, the other end of the connecting rod faces the pipe bending wheel, and a cushion block is arranged between the connecting rod and the machine frame. During pipe bending, a straight pipe firstly sleeves the end of the connecting rod, then the anti-shriveling plug is arranged in the straight pipe, then the straight pipe is put in the groove of the pipe bending wheel and fixed with the pipe bending wheel through the clamp, the power device is started to drive the spindle to rotate, and the pipe bending wheel is driven to rotate to bend the straight pipe to be semi-circular. The pipe bending machine is high in pipe bending efficiency and reduces the labor intensity of workers, and the pipe does not deform after being bent.

Description

technical field [0001] The invention relates to bending equipment for metal pipes, in particular to a pipe bending machine for bending circular hollow pipes into arc-shaped and semicircular pipes during the processing of pressure equalizing rings. Background technique [0002] The pressure equalizing ring is an annular hollow tube, which is made by manual beating or welding of two semicircular hollow tubes. The semicircular hollow tube is bent by a straight tube through a pipe bender. The existing pipe bender There is a defect that the hollow tube is seriously deformed during the tube, and the bent part is stretched, causing the tube wall to become thinner and shorten the life of the pressure equalizing ring. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a pipe bending machine with high pipe bending efficiency and no deformation after bending. [0004] The purpose of the present inventi...
