Abstract

The invention discloses a manufacturing method of a copper plastic pipe. The copper plastic pipe comprises a copper pipe; the copper pipe is coated with a fiberglass mesh; the outside of the fiberglass mesh is sprayed with high-temperature-resistant epoxy glue; a layer of aluminum tube is arranged outside the copper pipe sprayed with the high-temperature-resistant epoxy glue; a PPR material is formed outside the aluminum tube by injection molding. Thus, the manufacturing method of the copper plastic pipe, which has the advantages of smooth circumferential surface, complete smooth weld joints, heat preservation, large bearing capacity and high injection efficiency, is provided.

Description

technical field

[0001] The invention relates to a method for manufacturing a metal composite pipe, in particular to a method for manufacturing a copper-plastic pipe. Background technique

[0002] At present, with the advancement of science and technology, the application of copper-plastic pipes has become more and more popular. Copper-plastic pipes are used in both manufacturing and households. Therefore, the demand for copper-plastic pipes in today's market is increasing.

[0003] At present, the manufacturing methods adopted by a large number of pipe manufacturing enterprises are: feeding copper strips; forming copper pipes on copper strips by stainless steel automatic pipe making machines; welding the weld seams of formed copper pipes with welding machines; Heat; injecting PPR to the outer wall of the copper pipe, wherein the forming of the copper pipe and the injection molding of PPR on the outer wall of the copper pipe are carried out simultaneously on the same produc...

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] ①The copper strip 1 is fed, and the driving mechanism on the frame drives the mandrel 2 to rotate and move forward in the axial direction. The front end of the copper strip 1 is fixed to the front end of the mandrel 2. The width of the copper strip 1 is divided The included angle between the wire and the axis of the mandrel 2 is 20° to 40°, and the frame is fixed with an elastic device 14 for tightening the adjacent copper strips 1 wound on the mandrel 2;

[0041] ② Welding machine 3 welds weld seam 13, the driving mechanism on the frame continues to drive mandrel 2 to rotate and move forward, and the welding machine 3 with welding head aligned with weld seam 13 is fixed on the frame, and described weld seam 13 is made of copper The contact surface formed by two adjacent sides of the band 1 is pressed against each other, and the welding ...
