Pistol type welding gun equipment

Abstract

The invention relates to the technical field of welding gun equipment, and discloses pistol type welding gun equipment. A gun body is included. The upper end of the gun body is connected with a preheating bin, the upper end of the gun body is connected with a sliding key, the lower end of the sliding key is connected with a push rod, and a fan is arranged in the gun body. The right side of the fanis provided with a heating metal wire, the right side of the heating metal wire is provided with a gun barrel, the left side of an arc circular stop block is connected with a compression spring, an indication disc is connected to one side of the arc circular stop block, and the right end of the push rod is connected with a sliding block. The heating metal wire is electrified and generates heat, the sliding key is moved to the left side of a second transverse arc groove, hot air can evenly heat plastics which are placed in a preheating bin and easily absorb moisture through a heat dissipationpad, the arc circular stop block drives the indication disc to leftwards slide in a first transverse arc groove through a connecting rod, a longitudinal line mark on the indication disc corresponds toa scale plate, and the structure solves the problems that since preheating is not conducted, the seal performance of a welding face is poor, and the pressure cannot be visually judged.

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...
