Description

Welding gun cleaning device

Technical Field

The utility model relates to the technical field of welding, in particular to a welding gun cleaning device.

Background

Welding is a common manufacturing process, with fusion welding being one of the common welding approaches. In the fusion welding, a workpiece interface is heated to a molten state in the welding process, and the welding is finished in a mode of not pressing the pressure. During the fusion welding process, a flux aid, i.e. a welding wire, may be added as a wire welding material for the filler metal, if necessary.

At present, when welding is carried out by means of a welding wire, the welding gun needs to heat the welding wire into a molten state, and the welding wire in the molten state is embedded in a welding seam between two workpieces to be welded, so that the two workpieces are tightly connected after the welding wire is cooled. Due to the structural design of the nozzle of the welding gun, namely, the contact tip for accommodating the welding wire is arranged in the inner cavity of the nozzle shell, the welding wire in a molten state splashes to the inner wall of the nozzle shell in the guiding process, the welding wire in the molten state is attached to the inner wall of the welding gun to form attachments which are difficult to clean, and the attachments can possibly shield the outlet of the contact tip, so that the welding operation is influenced, the welding gun cannot be normally used, the maintenance rate of the welding gun is increased, and the service life of the welding gun is shortened. Meanwhile, the attachments may fall off during the welding process, and once the attachments fall off to the welding position, the welding quality of the product is affected.

Generally, the welding torch is cleaned with a tool, but the welding wire solution adheres during the subsequent welding process, and the welding torch cannot be substantially protected. In addition, when the tool peels off the deposit, the deposit directly contacts the inner wall of the welding gun, so that the cleaning operation also damages the inner wall of the welding gun, thereby reducing the service life of the welding gun.

In addition, when the welding gun is used, a part of welding wire may be blackened, the welding strength of the part of welding wire is weaker than that of a normal welding wire, and if the part of poor welding wire is continuously used, the connection strength between two workpieces is reduced, and the welding quality of the workpieces is affected.
