Embodiment 1

[0062] Figure 1-2 Shown is the method for manufacturing HDPE double-wall bellows, specifically comprises the following steps:

[0063] S1: install the inner wall extruder 2 and outer wall extruder 3 molds on the mobile car 1;

[0064] S2: Feed materials, turn on the inner wall extruder 2 to extrude the inner wall tube, open the outer wall extruder 3 to extrude the outer wall tube, the inner wall tube and the outer wall tube are formed by vacuum adsorption of the molding machine 4, and the corrugation is extruded by the molding machine 4 module. The feeding rack 5 delivers the pipes, and the pipes are cut by the cutting machine 6 .

[0065] The equipment for producing HDPE double-wall corrugated pipes is installed on the mobile vehicle 1, which facilitates the direct transportation of raw materials to the vicinity of the construction site, and the production of HDPE double-wall corrugated pipes on the mobile vehicle 1 is conducive to saving the transportation cost of finished...

Embodiment 2

[0102] Figure 1-2 It also shows a vehicle-mounted movable pipeline production line, including:

[0103] A movable car 1; inner wall extruder 2, outer wall extruder 3, molding machine 4, discharge rack 5, cutting machine 6 installed on the movable car 1; inner wall extruder 2, outer wall extruder 3 The extruded inner and outer wall sheets are absorbed and formed by the forming machine 4, and the corrugated tube is extruded by the module on the forming machine 4, and the corrugated tube is sent to the pipe by the discharge rack 5, and is cut by the cutting machine 6 into finished pipes.

[0104] The equipment for producing corrugated pipes is installed on the movable vehicle 1, which can directly transport raw materials to the vicinity of the construction site for nearby production, avoiding the loss of long-distance transportation of pipes.

[0105] As a further improvement of the vehicle-mounted movable pipeline production line of the present invention, it also includes a co...

Embodiment 3

[0112] The present invention relates to the production process of HDPE double-wall corrugated pipe:

[0113] 1. The installation and adjustment of the mold

[0114] 1.1 According to the production operation notice, replace the mold of the corresponding specification;

[0115] 1.2 The bolts of the connecting parts of the mold must be tightened, and tightened again after heating to the process temperature to prevent material leakage.

[0116] 1.3 When installing the cooling water jacket, the water inlet pipe should be below the water jacket, and the return pipe should be above the water jacket. The return pipe should be installed on the side of the extrusion die lip, and the gap between the root of the water jacket and the die head should be consistent on all sides. After installation, use a frame level to adjust the level of the water jacket.

[0117] 1.4 When installing the forming aluminum mold, ensure that the mold and base are clean, and tighten the compression bolts to p...

Abstract

The invention relates to a method for manufacturing an HDPE double-wall corrugated pipe on a vehicle-mounted movable pipeline production line and the vehicle-mounted movable pipeline production line, and aims at the method. The method specifically comprises the following steps of S1, mounting an inner wall extruder (2) and an outer wall extruder mold on a moving vehicle (1); and S2, feeding, starting the inner wall extruder to extrude an inner wall pipe, starting the outer wall extruder to extrude an outer wall pipe, performing vacuum adsorption molding on the inner wall pipe and the outer wall pipe by a molding machine (4), extruding corrugations by modules of the molding machine (4), feeding the pipes by a discharging frame (5), and cutting the pipes by a cutting machine (6). The vehicle-mounted movable pipeline production line comprises the moving vehicle, the inner wall extruder, the outer wall extruder, the molding machine, the discharging frame and the cutting machine. Plastic pipelines can be temporarily manufactured near a construction site, the transportation cost can be saved, and the transportation quantity can be increased.

Description

technical field [0001] The invention relates to a method for manufacturing HDPE double-wall corrugated pipes on a vehicle-mounted movable pipeline production line. [0002] The present invention also relates to the above-mentioned vehicle-mounted movable pipeline production line. Background technique [0003] With the introduction of the country's advocacy for the development of a double cycle economy, infrastructure construction and new infrastructure that stimulate domestic demand will usher in a new round of development opportunities. Various oil and gas transportation pipelines, municipal engineering pipelines, urban-rural integrated water supply and drainage pipelines, and intensive irrigation pipelines And so on have a huge market capacity. Because most of the pipeline products are dumped (especially large-diameter pipelines), the transportation cost is high. [0004] Chinese invention patent application publication CN111634037A, the publication date is 20200908, dis...
