Problems solved by technology

[0002] At present, plastic-aluminum composite pipes have been used instead of metal pipes as water pipes at home and abroad, but large-diameter plastic-aluminum composite pipes are still rare, and most of the piping materials used in chemical equipment are still metal pipes. There are many disadvantages such as easy to corrode, short life time, not environmentally friendly, easy to pollute, etc. There are not many other alternative forming pipe machinery and equipment, and even some production calibers are relatively small

Embodiment Construction

[0006] The present invention will be further described in conjunction with the accompanying drawings, the plastic pipe extruded by the inner layer thin-walled plastic pipe extruder (1) through the rubber material extruder (2) in the front is painted on the plastic pipe by the glue coating device. The outer circular surface of the plastic pipe is cooled by the cooling tank (3) in front to harden the plastic pipe and remove it from the steel strip (6) supported on the coil support (3) by cleaning and drying equipment (5). After derusting, degreasing, etc., it enters the steel pipe forming mold combination device together. The steel strip is gradually rolled and squeezed by the roller rolling mold to form a steel pipe and tightly wrapped on the outer circle of the plastic pipe, and then the lap welded by the rolling welding machine (7) Live, the rubber material extruded by the outer layer plastic material extruder (10) is applied to the outer surface of the steel pipe through the ...

Abstract

A composite tube forming device comprises a flow production line composed of an inner plastic pipe extruder (1), cooling grooves (3) and (12), a plastic extruder (2), a gluing device (4), a steel beltwashing and drying device (5), a steel pipe forming die combination device (8), a welder (7) and a traction device (11). The device has the characteristics of being simple in structure, easy to maintain, and low in cost; the produced plastic steel composite tube is high in diameter and high in pressure resistance, and cannot be corroded and oxidized, and the conveyed medium cannot be deterioratedand polluted; and the composite tube is a good tube for replacing a metal tube.

Description

technical field [0001] The invention relates to a composite pipe forming device, which belongs to the field of mechanical equipment. Background technique [0002] At present, plastic-aluminum composite pipes have been used instead of metal pipes as water pipes at home and abroad, but large-diameter plastic-aluminum composite pipes are still rare, and most of the piping materials used in chemical equipment are still metal pipes. There are many disadvantages such as easy to corrode, short life time, not environmentally friendly, easy to pollute and other defects. There are not many other alternative forming pipe machinery and equipment, and even some production calibers are relatively small. Contents of the invention [0003] In order to solve the above problems, the present invention provides a plastic-steel composite pipe forming device. The diameter of the plastic-steel composite pipe produced by it is increased. Pollution and deterioration greatly increase the service l...
