Abstract
The utility model discloses a tungsten argon arc welding penetration fusion welding gun, belongs to tungsten argon arc welding guns, and aims to provide a tungsten argon arc welding gun with centralized energy and big welding depth of fusion. The tungsten argon arc welding penetration fusion welding gun comprises a gun body with an air inlet pipe, an air spout fixedly connected with the gun body, a dog cannula fixed in the gun body and a tungsten electrode arranged in the cannula, wherein the hollow wall of the air spout (6) is provided with a helical cooling pipe (7), an electrode dog (2) is installed in a card slot (10) on the gun body (5), and the tungsten electrode (1) is inserted in the dog cannula (4) through a tungsten fixture (11) which is fixedly connected with the electrode dog (2). The utility model can realize reliable arc striking, and improve energy density of arc columns without changing power of an original welder and increasing arc strike control circuit, and the welding depth of fusion can be increased by more than 50%. The tungsten argon arc welding penetration fusion welding gun is an ideal tungsten argon arc welding gun.
Description
Technical field: the utility model relates to a kind of welding gun, relates in particular to a kind of tungsten argon arc welding gun.
Background technology: well-known, the tungsten electrode of traditional argon arc welding welding gun is non-telescoping stationary structure; Its operation principle is by producing welding arc by the pulse striking between tungsten electrode that stretches out nozzle and the workpiece.Because electric arc free combustion outside nozzle, it is horn-like that arc column is, and big, the straight and upright property of electric arc diffusion angle is bad, energy disperses, so welding penetration is less.If the bigger member of throat thickness is then wasted time and energy, production efficiency is lower.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of concentration of energy, argon tungsten-arc welding deep penetration welding rifle that welding penetration is big.
To achieve these goals, the utility model by the following technical solutions: it comprises the rifle body, the nozzle of fixedlying connected with this rifle body that are provided with air inlet pipe, be fixed on the dog sleeve pipe in the described rifle body and be arranged on tungsten electrode in this sleeve pipe; Be provided with spiral helicine cooling water pipe in the hollow wall of nozzle, the electrode dog is installed in the draw-in groove on the rifle body, and tungsten electrode is inserted in the dog sleeve pipe by the tungsten electrode chuck of fixedlying connected with the electrode dog.
Between electrode dog and dog sleeve pipe, be provided with spring.
Compared with the prior art, the utility model since on the basis of conventional tungsten electrode argon arc welding rifle fixedly tungsten electrode changed the bascule that can stretch up and down into, simultaneously nozzle wall has been changed into hollow-core construction and in nozzle wall, set up spiral helicine cooling water pipe, therefore reliably striking, can dwindle electric arc arc column diameter, raising arc column energy density again, thereby can significantly improve welding penetration, reduce the welding number of plies, enhance productivity, reduce production costs.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A among Fig. 1 is to view.
Among the figure: tungsten electrode 1 electrode dog 2 springs 3 dog sleeve pipes 4 rifle bodies 5 nozzles 6 cooling water pipes 7 air inlet pipe 8 water inlet pipes 9 draw-in grooves 10 tungsten electrode chucks 11
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～2, dog sleeve pipe 4 is fixed in the rifle body 5 that is provided with air inlet pipe 8, nozzle 6 is fixedly connected on the lower end of this rifle body, and the wall of nozzle 6 is the hollow interlayer structure, and spiral helicine cooling water pipe 7 is fixed in the hollow wall of nozzle 6 and is communicated with water inlet pipe 9 on being fixed on this nozzle; Be provided with two L shaped draw-in grooves 10 on the top of rifle body 5, the electrode dog 2 of fixedlying connected with tungsten electrode chuck 11 is installed in this draw-in groove, and tungsten electrode 1 is inserted in the dog sleeve pipe 4 by tungsten electrode chuck 11.For easy to use, between electrode dog 2 and dog sleeve pipe 4, be provided with spring 3.
During use, earlier by electrode dog 2 dead springs 3, nozzle 6 about 3～4mm are stretched out in the lower end of tungsten electrode 1 under the drive of tungsten electrode chuck 11, electrode dog 2 is withdrawed from from L shaped draw-in groove 10 after the pulse striking, spring 3 loosens and by the lower end that tungsten electrode chuck 11 the drives tungsten electrodes 1 5～6mm in the nozzle 6 that immediately upwards withdraw again; At this moment, the diameter of electric arc arc column is subjected to the stomidium restriction of nozzle 6, cooling water pipe 7 in the while nozzle 6 forms one deck cold air film at nozzle 6 inwalls, arc column conduction section further dwindles, current density further improves thereby force, and also there is compression in the magnetic field that arc column electric current itself produces to arc column, so under the acting in conjunction of above three kinds of pinch effects, the compression of welding arc column diameter, angle of flare diminish, the electric arc arc column is finger-like, the increase of the straight and upright property of electric arc, the arc column energy density is improved, thereby improves welding penetration.
Claims (2)
