A kind of pistol type welding torch equipment

Abstract

The invention relates to the technical field of welding torch equipment, and discloses a pistol-type welding torch equipment, which includes a gun body. Rod, the inside of the gun body is equipped with a fan, the right side of the fan is provided with a heating wire, the right side of the heating wire is provided with a gun barrel, the left side of the arc-shaped round stopper is connected with a compression spring, and the arc-shaped round stopper is connected with a compression spring. One side is connected with an indicator plate, and the right end of the push rod is connected with a slide block. By heating the metal wire to generate heat, move the sliding key to the left side of the second transverse arc-shaped groove, the hot air can evenly heat the hygroscopic plastic placed in the preheating chamber through the heat dissipation pad, and the arc-shaped round stopper passes through the connecting rod Drive the indicator to slide to the left in the middle, and the longitudinal line mark on the indicator plate corresponds to the scale plate. This structure solves the problem of poor sealing of the welding surface and the inability to judge the pressure intuitively due to no preheating.

Description

technical field [0001] The invention relates to the technical field of welding torch equipment, in particular to a pistol-type welding torch equipment. Background technique [0002] The welding torch refers to the part that performs the welding operation during the welding process. It is a tool used for gas welding. It is shaped like a gun. In recent years, the plastic technology has been greatly developed. There are probably two ways of plastic welding: one is blown out by the welding torch. Hot air at a higher temperature welds the weldment to the wood; one is by adding raw material to the gun, melting it first, and then extruding it onto the weldment. [0003] But that is the first plastic welding method that is not perfect enough to meet the welding process that people are beginning to pursue. For example: when plastic welding, the plastic to be welded is not preheated, and some special materials such as PA, ABS and PMMA etc., these are commonly used materials with seri...
