Automatic machining equipment for high-pressure steel-plastic composite pipe and machining method for steel-plastic composite pipe

Abstract

The invention relates to the technical field of steel-plastic composite pipe machining, in particular to automatic machining equipment for a high-pressure steel-plastic composite pipe. The device comprises a conveying device, a lifting device, a clamp and a heating device, the conveying device comprises two conveyors with conveying chains, a plurality of proximity switches are arranged on the side walls of one sides of the conveyors, the clamp comprises a telescopic air cylinder and an inflation pipe installed at the end of a push rod of the telescopic air cylinder, a branch pipe is welded to one side of the inflation pipe and externally connected with an air source, and a heating device is transversely arranged above the clamp. When the conveying chain conveys the steel pipe to the position corresponding to the V-shaped groove body of the tool apron, the proximity switch can sense the steel pipe, so that an operator can judge whether the steel pipe is in place or not; the plastic film in the steel-plastic pipe is inflated to be tightly attached to the inner wall of the steel pipe, and then the plastic film is hot-melted and bonded to the inner wall of the steel pipe through induction heating, so that the quality of the steel-plastic pipe is improved.

Description

technical field [0001] The invention relates to the technical field of steel-plastic pipe processing, in particular to automatic processing equipment for high-pressure steel-plastic composite pipes and a processing method for steel-plastic composite pipes. Background technique [0002] Steel-plastic pipe is a steel pipe product with a plastic film attached to the inner wall. During the processing of steel-plastic pipes, it is usually necessary to use a steel-plastic pipe compound machine to promote the adhesion of the plastic film to the inner wall of the steel pipe. For example, a Chinese patent discloses a fully automatic heating multi-tube type steel-plastic pipe composite machine, patent number 201821640206.0. It records: a fully automatic heating multi-tube steel-plastic pipe compound machine, including two conveyor chains that can transport steel pipes and are symmetrically arranged on the work table, and a limiter that supports the steel pipe on the upper surface of ...

Problems solved by technology

[0004] 1. The conveyor chain cannot guarantee that each steel pipe to be processed is just on the station. When the tool holder is raised, the steel pipe that has not been in place may be pushed away, causing production accidents;

[0005] 2. Although the steel pipe to be processed is put into the tubular plastic film in advance and melted under the heating of the induction coil, the plastic film put in is not tightly attached to the inner wall of the steel pipe. The position where the steel pipe contacts will eventually cause a bulge
