Description
Technical field
The utility model relates to welding field, is specifically related to a kind of gas shield device for welding.
Background technology
Non-ferrous alloy chemical property under hot conditions such as titanium alloy, aluminium alloy, magnesium alloy are active, and when the pollution that very easily is subject to surrounding environment causes welding, the quality of weld seam reduces, and then have influence on the mechanical performance of weldment.Therefore in welding process, for avoiding entering of under hot conditions pollution elements such as oxygen, hydrogen, nitrogen, generally need the butt welded seam high-temperature region to be protected.In current existing welding process often the front of a butt welded seam protected; and the butt welded seam back side is not protected; cause weldment directly to contact with air, or have directly consume a large amount of protective gas from front and manufacture protective atmosphere, cause welding cost to increase and the protection effect poor.
Summary of the invention
The purpose of this utility model is to provide a kind of gas shield device for welding; employing forms partial closure's gas shield pond in the weldment bottom; be filled with the inertia protective gas in the protection pond of whole sealing, thereby prevent its high-temperature oxydation, effectively solved the problems such as welding deformation.
The technical solution of the utility model is: a kind of gas shield device for welding comprises base, exhaustion plate and briquetting.
Described base is cuboid, wherein in the middle of the upper surface of cuboid, has concave through grooves, and the bilateral symmetry of concave through grooves has through hole, and seals respectively the first pipe is housed at the two ends in hole, by the first pipe, in through hole, injects cooling water.Have the hole of an end closure under concave through grooves, the second pipe is equipped with in the openend sealing in hole, by the second pipe, in hole, leads to inert gas.The bottom even of concave through grooves has some holes, and this hole communicates with the hole of an end closure under concave through grooves; The upper surface of base has screwed hole;
Described exhaustion plate is that top has arc groove, there is the cuboid of square groove below, some staggered through holes are arranged at the bottom of groove, the height of exhaustion plate is high consistent with the concave through grooves in the middle of base upper surface, has facing up of arc groove to be placed in the middle concave through grooves of base upper surface exhaustion plate; Exhaustion plate is stainless steel or copper material, exhaustion plate preferred material copper material;
Described briquetting is cuboid, and slotted hole is arranged on it, and the upper surface concave through grooves both sides that briquetting are placed in to base are fixed by screw.
Beneficial effect: the utility model is owing to having adopted exhaustion plate, make the steam vent that inert protective gas evenly is interspersed by exhaustion plate evenly spray, make inert protective gas be full of the space between exhaustion plate and welded piece, form the butt welded seam back side, gas storage pond and implemented good protection atmosphere; The discharge of being convenient to weld fumes and heat is not sealed at exhaustion plate arc groove two ends, has improved the protection effect; Movable exhaustion plate easily takes out from base groove, on easy cleaning exhaustion plate panel and the field trash on passage; Connect mobile cooling water by two cooling ducts, cooling welding work pieces, thus reduce the weldment workpiece temperature, solve high-temperature oxydation and reduced the problem such as welding deformation; Two symmetrical briquettings can be controlled well welding deformation in welding process, have improved welding quality.This device operating efficiency high and low gas consumption, weldquality are good, convenient operation, have reduced operator's labour intensity.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, a kind of gas shield device for welding, comprise base 1, exhaustion plate 2 and briquetting 3.
As shown in Figure 2, base 1 is cuboid, wherein in the middle of the upper surface of cuboid, has concave through grooves, and the bilateral symmetry of concave through grooves has through hole, and seals respectively the first pipe 4 is housed at the two ends in hole, by the first pipe 4, in through hole, injects cooling water.Have the hole of an end closure under concave through grooves, the second pipe 5 is equipped with in the openend sealing in hole, by the second pipe 5, in hole, leads to inert gas.Bottom one word of concave through grooves evenly has some holes, and this hole communicates with the hole of an end closure under concave through grooves; The upper surface of base 1 has screwed hole;
As shown in Figure 3,4, copper material exhaustion plate 2 has arc groove for top, there is the cuboid of square groove below, some staggered through holes are arranged at the bottom of groove, the height of exhaustion plate 2 is high consistent with the concave through grooves in the middle of base 1 upper surface, has facing up of arc groove to be placed in the middle concave through grooves of base 1 upper surface exhaustion plate 2;
Briquetting 3 is cuboid, and slotted hole is arranged on it, and the upper surface concave through grooves both sides that briquetting 3 are placed in to base 1 are fixed by screw.
The course of work: as shown in Figure 5, during use, first adjust the position of workpiece 6 to be welded with respect to exhaustion plate 2, make the back of weld of workpiece 6 to be welded be positioned at the centre of the arc groove of exhaustion plate 2, recycling briquetting 3 location also are fixed on workpiece 6 to be welded on base 1.The second pipe 5 is connected with gas cylinder by conduit, to justifying in the connected hole of the second pipe 5, rushes inert gas.The logical cooling water in the through hole connected to the first pipe 4 by the first pipe 4.Before welding; first logical inertia is protected gas; after making the through hole of inert gas by base 1 be full of exhaustion plate 2 bottom square grooves; the passage be interspersed on exhaustion plate 2 is filled to inert gas between exhaustion plate 2 and workpiece to be welded equably again; make in the welding dynamic process; inertia protection gas is evenly sprayed by the staggered passage on exhaustion plate 2, at the back of weld of workpiece 6 to be welded, forms stable guard space.Simultaneously, in whole welding process, the first pipe 4 forms two cooling ducts with the monosymmetric through hole of base 1 concave through grooves, and constantly flows through cooling water, thereby timely cooling welding work pieces finally reaches the purpose that realizes cooling welding work pieces.The flue dust produced in welding process and heat etc. are discharged by the exhaustion plate 2 untight semi-circular recesses in two ends, realize the inert gas shielding preferably of butt-welding fitting back of weld; After welding finishes, after workpiece 6 to be welded is cooling, lay down trip bolt, after close inertia protection gas, finally turn off cooling water, after exhaustion plate 2 is cooling, exhaustion plate 2 is cleared up in time unimpeded with the cleaning that guarantees exhaustion plate 2 and exhaustion plate 2 upper air-vents.
