A welding torch head

Abstract

The invention belongs to the technical field of electric welding equipment, in particular to a welding torch head, comprising a welding tip, a protective sleeve, a connecting pipe and a handle, wherein the protective sleeve includes an upper sheath and a lower sheath. In the form of mutual cooperation between the sheath and the lower sheath, the movement of the lower sheath is used to drive the internal scraper to remove the welding slag on the inner surface of the upper sheath, which reduces the damage between the protective sheath and the welding tip caused by improper cleaning of the inner end of the protective sheath. It can effectively reduce the influence of excessive welding slag accumulation inside the protective sheath on the welding quality, and greatly improve the working life and welding quality of the torch head; the upper sheath is equipped with spray anti-splash liquid to cool down The cooling box is provided with a rotating shaft, a cam and an air bag, and the movement of the lower sheath makes the splash-proof liquid in the air bag cool and cool the outer surface of the upper sheath, which strengthens the scraper against the welding slag on the inner wall of the upper sheath. Clean up effect.

Description

technical field [0001] The invention belongs to the technical field of electric welding equipment, in particular to a welding torch head. Background technique [0002] The welding torch refers to the part that performs the welding operation during the welding process. It is flexible, convenient and fast, and the process is simple. The welding torch uses the high current of the welding machine, and the heat generated by the high voltage gathers at the terminal of the welding torch to melt the welding wire. After the welding part is cooled, the objects to be welded are firmly connected into one. The power of the welding torch depends on the power of the welding machine and the welding material. The welding effect of the welding torch is qualified, the welding is safe, fast, the performance of the welding torch is reliable, and the maintenance is simple. It is easy to adjust; the welding torch does not need electricity, saves steel, and the equipment investment is small. [00...

AI Technical Summary

Problems solved by technology

[0003] During the welding process of the welding torch, due to the high welding current and long welding time, the welding process is often accompanied by the melting of metals and electrodes, resulting in splashed welding slag, which is deposited and solidified inside the protective sleeve of the welding torch tip, which is difficult to remove , has a certain impact on the quality of welding wire feeding and welding; in order to achieve high-quality welding results, the torch head must be cleaned frequently, but due to the special structure of the welding torch head, the conventional cleaning method is easy to damage the protective sleeve Damage to the welding tip, the operation is difficult and the cleaning is not clean, which greatly reduces the service life and welding quality of the welding torch tip
