Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, a welding gun device according to the present invention will be further described with reference to the accompanying drawings.

A welding gun device characterized by: the sheath is divided into two channels: 1: the cable channel is welded. 2: a wire feed tube passageway. The sheath channel function is butted in the front handle shell (the gun head of the welding gun) and the rear handle shell (the connection wire feeder) of the welding gun according to different structures, and the front handle shell and the rear handle shell are connected as required. Taking a manual air-cooling welding gun as an example: according to the classification and different functions of the welding guns, a control line and a compressed air channel are added. This manual air cooling welder sheath divide into four passageways: 1. 4 the cable and the protective gas channel are combined into one channel. 2 wire feed tube channel. And 3, controlling the line channel. 7 compressing the air channel.

After cable (naked) penetrates 1 passageway, because of there being suitable space, protective gas passes through and takes out the heat that cable (naked) generated heat and carries out welding protection, when stopping welding, if the cable high temperature, then start compressed air and cool down again to temperature controller in the shell, reach the settlement until the temperature. The compressed air can also be sprayed out of the channel to clean the weld bead, or the air can reach the front section of the channel of the wire feeding pipe 2 through the air outlet converter to perform back-blowing to clean the copper powder, and the copper powder is blown out to the inlet of the channel of the wire feeding pipe. The anti-splashing liquid can be sprayed to the inner wall of the nozzle and the surface of the weldment from the channel to the gun head to prevent welding slag. Compressed air enters the position near the handle shell before entering the compressed air channel 7, is blown out through the air outlet hole at the lower end, and forms a reaction force on the welding gun, so that the welding gun is lifted, and the weight and the working strength of the welding gun are reduced. 3 the control line channel is a manual torch switch. Automatic welding and special welding guns of robots, special machines and the like only have two channels: 1 welding cable channel. 2 wire feed tube channel.

The cable, the wire feeding and the gas discharging of the traditional welding gun are combined together, so that the cable cannot be cooled by water, and 5 and 6 cooling water channels can be added in the traditional welding gun, so that the cable can be cooled by water. The functions of the parts can be enhanced by combining the parts according to needs.
