Description

Novel water-cooling gun neck Technical Field The utility model relates to the technical field of welding guns, in particular to a novel water-cooled gun neck. Background The water-cooled gun neck is a key part for cooling a gun body in welding equipment, the water-cooled gun neck is externally connected with a circulating cooling water system, a large amount of heat is generated by welding arc in the welding process and can be transferred to the gun neck part, the water-cooled gun neck flows through cooling liquid in a circulating waterway to take away the heat generated by welding, so that the gun neck is kept in a lower temperature range, deformation and damage caused by overheating are avoided, and meanwhile, the welding quality can be ensured, and the service lives of the gun neck and related vulnerable parts can be prolonged. The utility model patent number 202022245596.5 discloses a novel efficient water-cooling gun neck structure, and the gun neck structure has the advantages that a water inlet path and a water return path are not arranged on the same layer, so that water flowing caused by the fact that water ribs between the two paths are not tightly sealed is avoided, a spray pipe region can be cooled simultaneously, and the cooling effect is better. However, the device still has some drawbacks in practical use, and obviously, when the water-cooling gun neck is used, although the water-cooling gun neck is provided with a multi-layer structure, water is prevented from being mixed, cooling water flows in the water-cooling gun neck, but channels which are mutually communicated are not arranged in the pipelines, although water mixing can be avoided, cooling water among the pipelines cannot be mutually mixed, and the flowing speed of the cooling water in the pipelines is too high, so that the cooling effect of the cooling water is poor. Therefore, it is necessary to invent a new type of water-cooling gun neck to solve the above problems. Disclosure of utility model The utility model aims to provide a novel water-cooling gun neck, which solves the problems that when the water-cooling gun neck is used, the water-cooling gun neck is provided with a multi-layer structure, so that the water is prevented from being mixed, cooling water flows in the water-cooling gun neck, but channels which are communicated with each other are not arranged in pipelines, the water is prevented from being mixed, the cooling water between the pipelines cannot be mixed, the flowing speed of the cooling water in the pipelines is too high, and the cooling effect of the cooling water is deteriorated.
