Description
Technical field
the utility model relates to Plate Welding gas shield device technical field, particularly a kind of Plasma Welding gas protective drawing closure assembly of corrosion resistant plate.
Background technology
plasma weldering is the conventional welding method in corrosion resistant plate welding, for the stainless steel weldment had higher requirements to stainless steel plasma face of weld, needs to carry out inert gas shielding to the weld seam in cooling.But the cover that drags common is at present all adopt the design of simple slot type structure, and distribution of gas is uneven, and weld seam protection effect is undesirable.
Utility model content
Technical problem to be solved in the utility model is to provide the Plasma Welding gas protective drawing closure assembly that a kind of structure is simple, significantly can alleviate the degree of oxidation of face of weld.
For solving the problems of the technologies described above adopted technical scheme: a kind of Plasma Welding gas protective drawing closure assembly; comprise the holder cover body of hollow and control to drag the position adjusting mechanism of cover body movement; the described chamber dragging cover body one to be provided with to hold torch neck; described to drag the other end of cover body to be provided with some to dragging in cover body the air inlet pipe passing into protective gas, drag the bottom surface of cover body to arrange between chamber and air inlet pipe to be provided with multiple gas flow making to drag the protective gas in cover body evenly to spray described.
Further, described in drag the bottom surface of cover body to cave inward to form cross section be the gas conduit of semicircle shape, described gas flow is the fumarole being spaced setting along gas conduit direction.
Further, the diameter of described fumarole is 1.5 ~ 2.0mm.
Further, one end extension of described gas conduit connects with dragging the end face of cover body, drags described the backing plate end face of cover body being also provided with confining gas conduit.
Further, each described air inlet pipe is threaded io by gas-tpe fitting and drags on cover body.
Beneficial effect: this plasma welding gas protective cover device is by adjusting the position of dragging cover body by position adjusting mechanism; protective gas passes into dragging in cover body through air inlet pipe; the metal surface, weld metal zone spraying also rear, uniform fold molten bath through gas flow with certain flow rate again forms a protective layer; under the effect of protective gas, effectively alleviate the degree of oxidation of face of weld.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the side view of the utility model embodiment;
Fig. 3 is the structural representation dragging cover body in the utility model embodiment.
Detailed description of the invention
Referring to figs. 1 through Fig. 3; a kind of Plasma Welding gas protective drawing of the utility model closure assembly; comprise the holder cover body 10 of hollow and control to drag the position adjusting mechanism 30 of cover body 10 movement; cover body 10 1 is dragged to be provided with to hold the chamber 11 of torch neck 40; dragging the other end of cover body 10 to be provided with some to dragging the air inlet pipe 20 passing into protective gas in cover body 10, arranging between chamber 11 and air inlet pipe 20 dragging the bottom surface of cover body 10 and being provided with multiple gas flow making to drag the protective gas in cover body 10 evenly to spray.
In the present embodiment, cover body 10 is dragged to be processed by one piece of copper coin, manufacturing process is simple, cost performance is good, without the need to water-cooled, during work, temperature distortion is little, drag cover body 10 in rectangular-shaped, the chamber 11 of one of cover body 10 is dragged to be made up of coaxial cylindrical cavity and conical cavity, it just matches with the end shape of torch neck 40, make the end of torch neck 40 can just put into chamber 11 to dragging cover body 10, the other end of cover body 10 is dragged to be to be threaded multiple air inlet pipe 20 by gas-tpe fitting 12, wherein the quantity of air inlet pipe 20 is determined according to requiring the bright degree of protected weld seam, two or three air inlet pipe 20 are normally set.Protective gas is through air inlet pipe 20 and passes into dragging in cover body 10, then forms a protective layer through the metal surface, weld metal zone that gas flow sprays also rear, uniform fold molten bath with certain flow rate.
In order to improve the protected effect on protective gas butt welded seam surface further, drag the bottom surface of cover body 10 to cave inward and form the gas conduit 13 that cross section is semicircle shape, this gas conduit 13 can hold the protective gas of ejection to prevent the too fast dissipation of protective gas, particularly, one end extension of this gas conduit 13 connects with dragging the end face of cover body 10, the end face dragging cover body 10 is also provided with the backing plate 14 of confining gas conduit 13, its effect is the end closing the gas conduit 13 dragged on cover body 10, prevent protective gas dissipation, the other end of this gas conduit 13 connects with the chamber 11 holding torch neck 40, gas conduit 13 arranges multiple fumarole 15 as gas flow along gas conduit 13 direction arrangement pitch, its axes normal is in the axis of gas conduit 13, the diameter of each fumarole 15 is 1.5 ~ 2.0mm.
The course of work of the utility model Plasma Welding gas protective drawing closure assembly is as follows: first air inlet pipe 20 to be connected to by gas-tpe fitting 12 and to drag on cover body 10, cover body 10 then will be dragged to be connected with position adjusting mechanism 30 by a plate 31.The end of torch neck 40 is placed in by the guiding mechanism of adjustment position adjusting mechanism 30 and plasma gun self chamber 11 dragging cover body 10.Welding centering also, after checking water, electricity and gas, can implement welding.During work; protective gas enters via air inlet pipe 20 and drags in cover body 10; being sprayed by fumarole 15 enters in the space surrounded by the end of gas conduit 13, torch neck 40 and backing plate 14 with certain flow rate again; and concentrate the metal surface, weld metal zone being covered in rear, molten bath, therefore significantly can alleviate the degree of oxidation of face of weld.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
