Problems solved by technology

[0003] Disadvantages of the exposed structure: the resistance wire is slightly higher than the surface of the pipe fittings, and the resistance wire is easily pushed off by the brutally operated pipe, resulting in a short circuit
[0004] Disadvantages of the plastic-coated wire structure: the plastic oxide layer on the welding surface of the pipe fittings cannot be eliminated; 2. Three-phase welding of pipes, pipe fittings, and plastic-coated wires, there are too many links, and it is easy to weld, which increases the hidden danger of welding
[0005] Disadvantages of post-filament structure: 1. Large investment in equipment; 2. High technical requirements, requiring trained personnel to produce products; 3. The blank needs aging treatment, and the processing cycle is long and the production cost is relatively high
4. Susceptible to welding environmental factors and human factors

Abstract

The invention discloses a tool for performing exposed type back wiring on a pipe body. The tool comprises a tool rack, a tool seat, a cutter and a roller, wherein the bottom of the tool seat is connected with the tool rack; a gap is formed in the top of the tool seat; the cutter is mounted on the tool seat, and is used for cutting an embedding slot for paving a resistance wire in the pipe body; the roller is positioned in the gap and can rotate, and the resistance wire is arranged on the outer circular face and is conveyed into the cut slot in the pipe body through rotation; the outer circular face of the roller presses the inner wall of the pipe body to embed the resistance wire on the outer circular face of the roller into the embedding slot of the pipe body. The tool for performing exposed type back wiring on the pipe body is stable in wire laying, controllable in precision and perfect in performance.

Description

technical field [0001] The invention belongs to the field of electro-fusion key processing equipment, and in particular relates to a tool for exposing and post-wiring a pipe body. Background technique [0002] The existing electric fusion pipe fittings are all equipped with resistance wires, and the structures for laying resistance wires generally include bare type, plastic-coated wire type and back-laid wire type, but the above-mentioned structure has the following disadvantages [0003] Disadvantages of the exposed structure: the resistance wire is slightly higher than the surface of the pipe, and the resistance wire is easily pushed off by the rough operation of the pipe, resulting in a short circuit. [0004] Disadvantages of the plastic-coated wire structure: the plastic oxide layer on the welding surface of the pipe fittings cannot be eliminated; 2. The three-phase welding of pipes, pipe fittings, and plastic-coated wires has too many links, which is prone to virtual w...
