Large-caliber steel pipe coiling machine

Abstract

The invention discloses a large-caliber steel pipe coiling machine. The large-caliber steel pipe coiling machine comprises a second machine body. A straight gear and a bevel gear are arranged in the second machine body and are in meshing connection through gear teeth. The outer wall of one side of the straight gear is rotationally connected with a hand wheel through a rotation shaft, a second leadscrew is welded to the outer wall of one side of the bevel gear, and the second lead screw is in screwing connection with a second screw nut base through a thread. A first supporting frame is arranged on the top of the second screw nut base, the top of the first supporting frame is in screwing connection with a first thread hand rod through a thread, a rotation roller is arranged at one end of the first thread hand rod, and a fourth motor is fixedly connected to the inner top of the second machine body through bolts. According to the large-caliber steel pipe coiling machine, on one hand, automatic circular pipe conveying can be guaranteed, the trouble of manpower pushing is reduced, and time and labor are saved; and on the other hand, constant-speed feeding can be achieved, consistent coil pipe curvature is guaranteed, the quality is improved, and the probability of defective goods is reduced.

Description

technical field [0001] The invention belongs to the technical field of coil processing, and in particular relates to a large-diameter steel pipe coil machine. Background technique [0002] Coil pipe is a spiral piping system, such as a disc-shaped aluminum-plastic pipe, such as a floor heating pipe coil installed in a back shape, and so on. [0003] However, most of the steel pipes on the existing building construction sites are placed in the open air, and the steel pipes are prone to rust. When the pipe machine is in use, it is necessary to manually transport the steel pipes. It is time-consuming and laborious, and at the same time it cannot be transported at a uniform speed. It is difficult to adapt to the coiling of steel pipes of different diameters. In addition, some large-diameter steel pipes have a large weight. The existing coil machine conveying device is difficult to transport stably, which is likely to cause jamming and stop, which affects work efficiency. Cont...
