[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Wire mesh skeleton polyethylene composite pipe is also referred to as wire pipe. It is a new type of pipe with a mesh skeleton formed by left and right spiral winding of high-strength steel wire as the reinforcement, high-density polyethylene (HDPE) as the matrix, and high-performance HDPE modified adhesive resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene.

[0004] The wire mesh skeleton polyethylene composite pipe is connected by electric hot-melt connection and flange connection. As one of the flange connection methods, the integral flange connection heats the pipe end and uses a special mold to press the end into a flange root, and then uses an iron flange connection.

[0005] When pressing the flange root of the steel wire pipe, the steel wire pipe flanging machine is used to process it. When heating the pipe port, the pipe needs to be inserted into the heating oven of the flanging machine. The pipe rotates to ensure uniform heating. During the rotation process, the pipe will shift laterally, and the larger the pipe diameter, the more obvious the displacement phenomenon. This phenomenon will cause the heating depth of the pipe port to be insufficient, which is easy to cause quality problems of the port flange root. Utility Model Content

[0013] As a further technical solution, the guide rod is slidably connected to the support seat, and the guide rod can move horizontally.

[0014] As a further technical solution, the axis of the roller is arranged vertically, and the roller can rotate horizontally.

[0015] As a further technical solution, the roller is coated with a polyurethane layer.

[0016] As a further technical solution, the base is arranged horizontally, one end of the base is fixedly connected to the platform foundation, the other end of the base is suspended, and a leveling cylinder is arranged on the top of the suspended end of the base.

[0017] As a further technical solution, a reinforcing rib plate is provided at the bottom of the base, and the side of the reinforcing rib plate is fixedly mounted to the side of the stand foundation.
