Description
Technical field
The present invention relates to a kind of metallic nozzles with the ultra-narrow gap MAG/MIG automatic welding guns of ignition tip insulation, belong to
Welding technology field.
Background technology
Welding technology since industrial circle is applied, has early had become the most widely used connection of equipment manufacturing at the beginning of last century
Technology.As modern industry is equipped to the quick universal of high power capacity high parameter, the enlargement of industry equipment, heavy-duty, high strengthening
Have become the most important characteristics of current equipment manufacture.The enlargement of industry equipment, heavy-duty bring welding engineering amount at geometry
The increase of series, the contradiction between welding productivity and manufacturing cycle, manufacturing cost become increasingly conspicuous.Narrow gap/ultra-narrow gap MAG/
MIG welding techniques are due in welding productivity, as-welded welding quality, welding production cost etc. and existing widely applied arc
Welding technology is compared, and has revolutionary technological progress, it has also become the new lover of 21 century high end advanced manufacturing technology will quickly substitute
Existing tradition welding technology, relatively advanced narrow-clearance submerged arc welding technology, heated filament pulse narrow gap TIG welding technologies have become
Trend of the times.
However existing narrow gap/ultra-narrow gap MAG/MIG technical fields, protective gas nozzle be in its welding gun technology most
Important component, fine structure not only decide that the metallurgical protecting effect of welding high-temperature region, service life also decide welding life
Yield and welding production cost.Gas shield nozzle made of insulating materials is relatively mostly used in prior art, as ceramic material sprays
Mouth, high temperature resistant composite nozzle etc..Such nozzle due to using at present close to arc region by photo-thermal width according to strongly
Very undesirable on service life, aging embrittlement failure is difficult to prevent, especially structural ceramic material nozzle, and there is also electric arc is worked
Rupture falls molten bath in journey, and the side wall that ignition tip and part are discharged and burnt between ignition tip and two side is caused after exposed ignition tip
The extreme matters of aggravation of groove occurs.Also there is the gas shield nozzle being made of metal material (such as tradition half in prior art
Automatic gas shielded welding gun), it is insulated between the ignition tip at middle part from structure using insulating materials, but in narrow gap/super
Narrow gap MAG/MIG welds field, and the shunting uniform flow technology of nozzle interior is still undesirable, leads to the primary metallurgical guarantor to high-temperature region
It is poor to protect effect, it is necessary to still ensure to protect the good metallurgy of welding high-temperature region by second protection outside the groove of big flow,
This will lead to the increase of welding material expenditure increased by a relatively large margin with welding production cost.Therefore, overcome above-mentioned limitation, adopt
Gas shield nozzle is manufactured with metal material, the reliable insulation between ignition tip, and it is real under the shield gas flow rate of very little
Now to the good protection of welding high-temperature region, it has also become improve the tight of narrow gap/ultra-narrow gap MAG/MIG automatic arc welding technologies today
Urgent technological progress task.
Invention content
The present invention, which overcomes the limitation of the prior art, to be realized by following proposal：
A kind of ultra-narrow gap MAG/MIG welding gun metallic nozzles with ignition tip insulation, including seal wire conductive body, setting exist

Room, top are decompression splitter cavity, and middle part is uniform flow chamber, and lower part is diversion cavity.The lower part for depressurizing splitter cavity is equipped with flow distribution plate, uniform flow
It is sieved equipped with uniform flow the lower part of chamber.Flow distribution plate is platy structure, and there are three the ascending waney tap hole of diameter, installations at middle part
When the superposed air inlet seat side of path nose end.Uniform flow sieve is platy structure, smooth equipped with being mutually parallel in its thickness direction
Aperture (uniform flow hole) sprays into welding high-temperature region to limit the equal parallel direction of all gas particle.The uniform flow hole in neighbouring ignition tip region
Density is closeer, and the uniform flow hole far from ignition tip region is diluter, and density larger side is located at open diversion cavity side.
The two pieces nozzle body of mirror image is integrated with appellation metallic nozzle after flow distribution plate and uniform flow sieve, pacifies respectively
Arranged on left and right sides loaded on ignition tip.The open chamber of two pieces metallic nozzle short transverse is close to the installation of ignition tip both sides；And point
It is not connected by two air guide ontologies of the screw and top in screw hole.
Nozzle body is manufactured with the good fine copper of heat conduction or ormolu.
The bottom of nozzle body is equipped with circulating water passage.Circulating water passage enters from the upper end water-logged base of open side wall,
From the upper end backwater base outflow of another open side wall after bottom cycle.
Seal wire conductive body and air guide ontology constitute the agent structure of ultra-narrow gap MAG/MIG welding guns, see patent of invention
" a kind of bending ultra-narrow gap MAG/MIG welding guns ".
Water, gas unicom and its sealing structure between metallic nozzle and air guide ontology are shown in a kind of patent of invention " bending ultra-narrow
Gap MAG/MIG welding guns ".
Insulation system between seal wire conductive body and air guide ontology is shown in a kind of patent of invention " bending ultra-narrow gap MAG/MIG
Welding gun ".
Ignition tip between two metallic nozzles is the ignition tip of periphery insulation, sees a kind of patent of invention " ultra-narrow of surface insulation
Gap MAG/MIG welds ignition tip ".
The present invention has following remarkable advantage：1, between metallic nozzle and conductive structure while mutually insulated, due to cycle
Water cooling results in service life height, and splashing is not easy to gather in end, and is easy to remove；2, the importing of protective gas to welding high-temperature region is complete
Entirely parallel with welding wire axis, laminar flow protecting effect is excellent；3, satisfactorily protecting effect is can reach under smaller gas flow, removed
Secondary cap weld, a small amount of layer of cap weld need outside second protection, account for the underfill weldering of the welding engineering amount overwhelming majority
Layer and central filler layer, need not add second protection, substantial saved the consumption of protective gas；4, the service life of metallic nozzle
It increases substantially, is hundreds times ceramic, composite material nozzle life；5, the flow distribution plate inside metallic nozzle, uniform flow sieve are side
Just detaching structure, and the service life, up to the several years, when external nozzles ontology needs replacing, internal structure can still be used for a long time.
