Description
Technical field
The present invention relates to pipeline welding field, particularly a kind of stainless steel termination single face welding and double face shaping welding tooling.
Background technology
All single-side welding double-side forming is required in the welding process of stainless steel pipeline and termination.Currently used welding method is: one of pipeline is blocked with stopper; to pipeline, its body of protection (argon gas) is filled from other one; then utilize argon arc welding or other welding manner to weld in the outside of pipeline, thus reach the single-side welding double-side forming of weld seam.The subject matter of this welding method is: 1. need tubular body all to fill protective gas with in welding process, cost is higher.2., because one end of body blocks, one end is constantly to tubular body inflation in addition, and air pressure inside is difficult to control to best welding surroundings, the more short more difficult control of body.If air pressure is comparatively large, gas externally can be spread from inside by welding bead, causes that welding process peripheral is shaping badly maybe cannot be welded.If air pressure is less, the internal protection of welding bead is inadequate, and the shaping meeting of inner welding bead is incomplete, affects welding quality.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of stainless steel termination single face welding and double face shaping welding tooling, makes the welding process of pipeline and termination simple, with low cost, and ensures welding quality.
For solving the problems of the technologies described above, the invention provides a kind of stainless steel termination single face welding and double face shaping welding tooling, this frock monnolithic case becomes stair-stepping cylindrical, axle center place, described frock rear portion is provided with air admission hole, excircle is evenly provided with four ventholes in the middle part of described frock, described air admission hole and described venthole through.
Further, described frock rear portion cylinder internal diameter is greater than pipe head internal diameter, and in the middle part of described frock, cylinder internal diameter is less than pipe head internal diameter 1mm, the anterior cylinder internal diameter of described frock 2mm less of described middle part cylinder internal diameter.
Further, in the middle part of described frock, the length of cylinder is less than termination length 3mm.
Further, described venthole be positioned at the anterior cylinder of described frock near with cylinder junction, middle part.
Further, described venthole to be positioned near welding bead and after welding bead.
Further, the aperture of described air admission hole is 6mm, and the aperture of described venthole is 4mm.
Further, the material of described frock is copper.
Stainless steel termination provided by the invention single face welding and double face shaping welding tooling, can make the welding process of body and termination simplify, and make the inner shaping uniformity of welding bead good, and processing cost is low, welding quality is high, can enhance productivity.

The stainless steel termination single face welding and double face shaping welding tooling sectional view that Fig. 2 provides for the embodiment of the present invention.
The stainless steel termination single face welding and double face shaping welding tooling operation principle schematic diagram that Fig. 3 provides for the embodiment of the present invention.
Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 3, a kind of stainless steel termination single face welding and double face shaping welding tooling that the embodiment of the present invention provides, monnolithic case becomes stair-stepping cylindrical, comprise anterior cylinder 1, middle part cylinder 2 and rear portion cylinder 3, axle center place, frock rear portion is provided with air admission hole 4, excircle is evenly provided with four ventholes 5 in the middle part of frock, air admission hole 4 is through with venthole 5; Frock rear portion cylinder 3 internal diameter is greater than pipe head 6 internal diameter, in the middle part of frock, cylinder 2 internal diameter is less than pipe head 6 internal diameter 1mm, can ensure that the center line of welding tooling is consistent with the center line of termination 6, protective gas is avoided to flow backward, also can avoid owing to having welded follower head 6 and welding deformation occurs body 7 in actual mechanical process, and the situation that the welding tooling caused is got to get off occurs simultaneously; Anterior cylinder 1 internal diameter of frock 2mm less of middle part cylinder 2 internal diameter, make to leave gap between welding tooling front portion and body, be convenient to unnecessary protective gas therefrom flow out, protective gas is avoided to flow out not smooth and occur that body 7 internal gas pressure is excessive, protective gas externally can be spread from body 7 inside by welding bead 8, causes that welding process peripheral is shaping badly maybe cannot be welded; In the middle part of frock, the length of cylinder 2 is less than termination 6 length 3mm; Venthole 5 be positioned at the anterior cylinder 1 of frock circumferentially and near with middle part cylinder 2 junction; and venthole 5 to be positioned near welding bead 8 and after welding bead 8; so not only make protective gas form the gas field of local in welding bead 8 inside and protect welding bead, the protective gas simultaneously avoiding venthole 5 to flow out directly blows welding bead 8 and causes and cannot weld.
Copper elected as by the material of a kind of stainless steel termination single face welding and double face shaping welding tooling that the embodiment of the present invention provides, because in stainless steel welded process, copper does not melt mutually with stainless steel, after avoiding welding to complete, welding tooling and workpiece are sticked together, simultaneously because the hardness of copper is softer, in the process of Installed card, be not easy gouge workpiece.
The operation principle of a kind of stainless steel termination single face welding and double face shaping welding tooling that the embodiment of the present invention provides is: by the shunting of frock to protective gas; compress the Existential Space of protective gas simultaneously; make protective gas close to welding bead; the gas field (i.e. the space of protective gas existence) of a local is formed in welding bead inside; thus in welding process, play internal protection effect, make welding bead reach single-side welding double-side forming.Specific works process is: with reference to Fig. 3, the air admission hole 4 of frock and tunger tube are connected together, then welding tooling is inserted in inside termination 6 and body 7; Air admission hole 4 and 4 ventholes 5 of welding tooling are through, and the position of venthole 5 is near welding bead 8; When air admission hole 4 starts to be input into argon gas, argon gas is exported through 4 ventholes 5 by the conversion of frock, because the space between the anterior cylinder 1 of welding tooling and body 7 is very little, and the position of venthole 5 is after welding bead 8, therefore the argon gas exported can rest near welding bead 8 for a long time, and forms the small-sized gas field of a local.Adopt argon arc welding welding from the outside of body so again, welding bead just can be made to reach the object of single face welding and double face shaping.
Stainless steel termination provided by the invention single face welding and double face shaping welding tooling, mainly contains following advantage:
1, adopt this welding tooling to weld, highly difficult welding process is become simple.
2, because the space between frock and workpiece is less, and the size in space is even, and the therefore inside beautiful appearance of welding bead, uniformity is good.
3, the demand of protective gas reduces, and processing cost is reduced.
4, adopt this frock to weld, be easy to the quality ensureing welding bead, thus enhance productivity.It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
