Air pressure pipe bending machine

Abstract

The invention discloses an air pressure pipe bending machine. The machine comprises a worktable, a cylinder (5), a cylinder component, a pipe bending pressure tank (7) and rolling grooves (8), wherein a cylinder piston of the cylinder (5) is connected with the pipe bending pressure tank (7) through a telescopic shaft rod (6); the pipe bending pressure tank (7) is provided with a semi-circular notch of which the diameter is matched with that of a pipe; the worktable is provided with two rolling grooves (8) for positioning the two ends of the pipe and matching with the pipe bending pressure tank (7) to bend the pipe; each rolling groove (8) is provided with a semi-circular notch of which the diameter is matched with that of the pipe; and the cylinder piston moves forwards or backwards to push the telescopic shaft rod (6) and the pipe bending pressure tank (7) to move forwards or backwards along the direction of the worktable. The machine is high in pipe bending quality, ensures consistent and attractive bends, has high work efficiency, is not required to be operated by professional personnel, saves labor cost, is suitable for bending short pipes, can improve the utilization rate of the short pipes in a construction site, and reduces material loss.

Description

technical field [0001] The invention relates to a pneumatic pipe bending machine. Background technique [0002] At present, in the field of building electrical construction, the bending pipes of steel conduits are mainly bent by hand pipe benders. The quality of the pipe bends is not high, and it is easy to cause bending and collapse, resulting in damage to the insulation layer of the wires in the pipe. Manual pipe bending is labor intensive and construction efficiency is low. And the short pipes cut off on site can no longer be used, resulting in waste of steel conduits. Contents of the invention [0003] The object of the present invention is to provide a pneumatic pipe bending machine with simple structure, good pipe bending quality and high working efficiency. [0004] The technical solution of the present invention is: a pneumatic pipe bending machine, which includes a workbench, a cylinder and a cylinder assembly, a pipe bending groove, and a rolling groove. The p...

[0002] At present, in the field of building electrical construction, the bending pipes of steel conduits are mainly bent by hand-pulled pipe benders. The quality of the bent pipes is not high, which is easy to cause bending and deflation, resulting in damage to the insulation layer of the wires in the pipe.
