Abstract
The invention relates to an injection type welding gun. The injection type welding gun comprises an injection rod, a cavity, a heating device, an insulating partition board, a melting cavity and an injection cavity, wherein the periphery of the interior of the cavity is partitioned into an independent space by the insulating partition board, and the heating device is arranged in the independent space; the injection cavity is formed in the middle of the cavity, one end of the injection cavity is connected with the injection rod, and the other end of the injection cavity is connected with a nozzle of the welding gun; welding liquid inlets are formed in the periphery of the injection cavity; the welding cavity is formed between the insulating partition board and the injection cavity; a welding wire enters the melting cavity through one side of the cavity. According to the injection type welding gun, the welding wire enters the injection cavity after being molten in the melting cavity and is pressed into the nozzle of the welding gun in a certain pressure through the injection rod, so that cavity type gaps with complex structures and narrow intervals can be welded.
Description
Technical field
The present invention relates to a kind of welding gun, especially relate to a kind of injecting type welding gun.
Background technology
At present, electric torch is all generally to adopt electrical heating, and welding rod makes its fusing by the rear directly contact of welding gun end heating, then utilizes spot welding welding position, welding gun end.The welding gun of this structure is suitable for the welding in shallow table position and simple large gap, but for complex structure, the welding in the cavity type gap of narrow gaps, after wire melting, welding fluid is difficult to flow into, and often causes defects such as lacking weldering.
Summary of the invention
The object of the invention is to overcome above defect, a kind of injecting type welding gun of the cavity type gap welding that is suitable for labyrinth is provided.
Technical scheme of the present invention is: a kind of injecting type welding gun, it comprises injection rod, cavity, heater, molten chamber and injecting cavity, the inner periphery of cavity is isolated into an independently space with insulating barrier, heater is arranged on this independently in space, middle part at cavity is provided with injecting cavity, one end of injecting cavity is connected with injection rod, the other end of injecting cavity is connected with torch neck, around injecting cavity, be provided with welding fluid entrance, between insulating barrier and injecting cavity, form molten chamber, welding wire enters into molten chamber by a side of cavity.
For welding fluid is discharged fast, the end of described injecting cavity inner end and injection rod is taper.
The angle of described taper is 120 degree.
Described welding fluid entrance is 4.
Useful technique effect of the present invention is due to welding wire is entered into injecting cavity after fusing in molten chamber, then to be pressed into torch neck by injection rod with certain pressure, thereby can to realize the welding in the cavity type gap of labyrinth narrow gaps.
