Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] A processing method for a high-density polyethylene winding structure wall pipe, comprising the following steps:

[0050] (1). Prepare a continuous S-shaped electric heating wire with an electric heating wire processing device.

[0051] The electrothermal guide wire processing device includes a wire reel 1100 , a straightening mechanism 1200 , a wire guide mechanism 1300 , a wire bending mechanism 1400 , a shovel wire body 1500 and a frame 1600 .

[0052] The unprocessed electric heating wire is wound on the winding reel 1100 . The reel 1100 is rotatably connected with the frame 1600 . The electric heating guide wire enters the inlet end of the straightening mechanism 1200 from the winding reel 1100 .

[0053] The electrothermal guide wire is pulled and straightened by the straightening mechanism 1200 , and then input to the godet wheel 1305 . The ...

Abstract

A method for processing a high-density polyethylene winding wall pipe, belonging to the technical field of pipe processing methods, comprising the following steps: (1) using an electric heating wire processing device to prepare a continuous S-shaped electric heating wire; (2) using two ends The cutting device trims the outer surface of the socket and socket of the high-density polyethylene winding structure wall pipe; (3) demolds the high-density polyethylene winding structure wall pipe with a worm shrinking device; (4) uses the positioning fixture to remove the electric heat The guide wire is fixed on the inner wall of the high-wall pipe socket, and then the heating wire is energized to raise the temperature, so that the heating wire is evenly embedded in the inner wall of the socket in a continuous S-shaped circumferential direction; (5) Plug the socket into the socket; after power on , The socket interface and the socket interface are welded and sealed with each other. The invention adopts a socket-type electric fusion connection, and an electric fuse is embedded in the socket end. When the pipeline is connected, only the power supply is needed to complete the welding. The construction is convenient, and the pipeline system realizes zero leakage.

Description

technical field [0001] The invention belongs to the technical field of pipe processing methods, and in particular relates to a processing method for high-density polyethylene winding structure wall pipes. Background technique [0002] High-density polyethylene (HDPE) winding structural wall pipe is made of high-density polyethylene. It is a structural wall flexible pipe with smooth inner wall and spiral ribs on the outer wall. High-density polyethylene (HDPE) winding structure wall pipe is an environmentally friendly, safe and energy-saving product. It is light in weight, flexible, stable in chemical properties, corrosion-resistant and aging-resistant. It is an ideal substitute for cement pipes, steel pipes and other sewage pipes. [0003] However, the traditional processing method of high-density polyethylene (HDPE) wound structure wall pipe is to butt the two pipes and bond them with adhesive. The plug-in pipe head is not machined, the plug-in precision is not high, it is...
