Air-cooled welding torches for automatic welding lines

Abstract

The invention relates to an air-cooled welding gun for an automatic welding production line. For the water-cooled welding gun in the prior art, because the welding gun is limited by the structure, during welding, the situations of damage, water leakage and the like are frequently generated. The air-cooled welding gun for the automatic welding production line, which is provided by the invention, comprises a gun body (6), wherein a threaded sleeve (4) at the front part of the gun body is fixed on the gun body through a baffle ring (2), an insulated baffle ring (3) and an insulated sleeve A (5), a connecting pipe (8) and an insulated sleeve B (9) are mounted at the tail of the gun body, the gun body and the surface of the connecting pipe are wound by an insulated adhesive tape, and a connector (10) is mounted at the tail of the connecting pipe. The air-cooled welding gun is used for the welding guns of the automatic welding production line.

Description

[0001] Technical field:

[0002] The invention relates to an air-cooled welding torch used in an automatic welding production line.

[0003] Background technique:

[0004] At present, the welding torches on the automatic welding production line need to cool the welding torch body while welding due to continuous welding. The original water-cooled welding torch is limited by the structure of the welding torch, so damage and water leakage often occur during the welding process. The water-cooling part of the welding torch will produce a large amount of rust as the welding temperature rises, causing the problem of blockage of the cooling water circulation part and poor water cooling effect. This kind of water-cooled torch brings great inconvenience to production.
