PE pipe quick welding device

Abstract

The invention relates to a PE pipe quick welding device. The PE pipe quick welding device comprises a left clamping assembly and a right clamping assembly which are arranged in a spaced manner, the left clamping assembly comprises a third clamping ring and a fourth clamping ring, the end face of the third clamping ring extends outwards to form a third outer edge, the end face of the fourth clamping ring extends outwards to form a fourth outer edge, and the third outer edge and the fourth outer edge are connected through a second sliding rod. The right clamping assembly comprises a first clamping ring and a second clamping ring, the end face of the first clamping ring extends outwards to form a first outer edge, the end face of the second clamping ring extends outwards to form a second outer edge, and the first outer edge and the second outer edge are connected through a first sliding rod. According to the PE pipe quick welding device, no base design is adopted so that the equipment can move along a pipeline, and the in-site transfer difficulty caused by separated accessories is reduced due to the integrated design; and the clamping rings are internally provided with fuse machines, so that the radial heating depth of a pipe is greatly improved, and the hot melting quality is improved.

Description

technical field [0001] The invention relates to the field of welding of non-metallic pipes, in particular to a fast welding device for PE pipes. Background technique [0002] PE pipes for water supply are replacement products of traditional steel pipes and polyvinyl chloride drinking water pipes; the PE pipe welding process mainly uses automatic or semi-automatic butt welding machines, and the steps are clamping and alignment of the pipe body, cutting of the pipe end, and heating of the pipe end , Pipe butt joint and radial pressure. [0003] Different butt welding machines adopt fixed base + double ring or four ring structure in the process of clamping and aligning the pipe body; manual cutters or separate electric milling cutters may be used in the pipe end cutting process; most of the pipe end heating process adopts separate heating Plate (hot-melt machine); radial pressure can be driven by hydraulic pressure or manpower. [0004] Due to the fixed machine base, the pipe...

AI Technical Summary

Problems solved by technology

[0004] Due to the fixed machine base, the pipelines within the construction scope must be concentrated near the welding machine to complete the welding, and then transported to the installation location; small equipment, centralized pipelines in partitions, and multiple equipment invested at the same time can alleviate the impact of this shortcoming to a certain extent, but cannot completely eliminate it

This shortcoming directly causes welding to become the pre-work of pipeline layout in engineering, and there is no possibility of parallel operation; the cutting and heating process depends on separate equipment, and the degree of integration is low. In addition to the fixed machine base, it is difficult to transfer in the field ;The heating plate of the separate hot-melt machine is circular, and it is placed in the middle of the two cut pipes to heat the pipe end at the same time; this heating leads to insufficient heating depth in the radial direction, especially for large-diameter PE pipes. Good, it will affect the welding effect
