Abstract
The utility model provides a welder for thick plate narrow gap welding, includes the body of a gun, leads electric nozzle and outer protection jacket, and lead electric nozzle's length and process to 120mm, and outer protection jacket and to lead electric nozzle isometric. This welder is applicable to the weldment welding of using narrow clearance technology more than the thickness 30mm, can guarantee that CO2 gas guarantor welds, the submerged arc welding normal operation.
Description
Technical field:
The utility model belongs to welding equipment, particularly a kind of welding gun for slab narrow gap welding. CO2Gas is protectedProtect weldering, submerged arc welding.
Background technology:
At industry and civilian construction field, along with the maximization of steel construction, slab, ultra-thick plate are applied more and more general at presentTime, therefore narrow gap welding has obtained promotion and application as outstanding welding procedure. But in narrow gap welding, have oneIndividual obvious problem: along with thickness of slab is increasing, application CO2When gas is protected weldering, submerged-arc welding, gas is protected welding gun protective sleeve or submerged-arc welding is ledSparking plug very easily touches weld seam sidewall, forms sparking; If raise ignition tip, can solve the problem of touching sidewall, but cause gasBody protection deleterious or submerged-arc welding wire stretch out long, cause the defects such as current interruption, pore, slag inclusion, lack of fusion, and then impactTo welding parameter and the mechanical property of weld seam.
Summary of the invention:
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and provides a kind of for slabThe welding gun of narrow gap welding, this welding gun is applicable to the weldment welding of the narrow gap of the above application of thickness 30mm technique, can ensure CO2Gas is protected weldering, submerged-arc welding normal operation.
As above design, the technical solution of the utility model is: a kind of welding gun for slab narrow gap welding, comprises rifleBody, ignition tip and outer jointing jacket, is characterized in that: the length of ignition tip is machined to 120mm, and outer jointing jacket and ignition tip etc.Long.
Above-mentioned ignition tip is oblate body shape, and thickness is 8-10mm.
Above-mentioned outer jointing jacket is oblate body shape, and thickness is 8-10mm.
The utlity model has following advantage and good effect:
1, the length of ignition tip is added to 120mm by the utility model, to adapt to slab, the ultra-thick plate of thickness at 80-160mmWelding requirements, ignition tip can stretch into weld seam inside, makes gas shield that gas protects weldering more comprehensively, the welding wire work of submerged arc welding effectRate is higher.
2, because slab narrow gap weld seam width is fixed value 17-25mm, along with weldment thickness increases, the cylinder of standardShape tip can not meet welding requirements, and therefore, ignition tip is processed as oblate shape (width 8-10mm) by the utility model, can make welderingMouth stretches into weld seam inside and does not touch with weld seam sidewall, can meet narrow gap welding requirement completely.
3, because slab narrow gap weld seam width is fixed value 17-25mm, for meeting weld width requirement, the utility modelOuter jointing jacket is pressed into oblate body by cylinder, can meets most of narrow gap weld seam requirement.

Detailed description of the invention:
As in Figure 3-5: a kind of welding gun for slab narrow gap welding, by the welding gun body of a gun 1, ignition tip 2a and outer protectionCover 3a composition. The welding gun body of a gun 1 does not change, and ignition tip 2a adds and grows to 120mm, is threaded with the welding gun body of a gun 1, uses red copper bar machineProcess. The effect of outer jointing jacket 3a is that protection ignition tip 2a does not contact with weldment, the equivalent damage that do not splashed, and constraint is simultaneously protectedProtect gas and concentrate on welding pool place, must be isometric with ignition tip 2a after therefore protective sleeve 3a is installed on the welding gun body of a gun 1, andMeet narrow gap welding requirement. Because narrow gap weld seam width is fixed value (being generally 17-25mm), for meeting weld widthRequirement, is pressed into oblate body by ignition tip 2a and protective sleeve 3a by cylinder, and oblate 8-10mm can meet most of narrow gapWeld seam requirement. (duty is shown in Fig. 6)
CO2When gas shielded arc welding, welding gun stretches into weld seam inside, and ignition tip 2a helps welding wire, makes it enough rigidity notAs for touching with weld seam sidewall, and because ignition tip stretches into weld seam inside, make welding wire more accurate positioning, appearance of weld more can meetDesigning requirement; Protective sleeve 3a stretches into weld seam inside in addition, can make protective gas more concentrated, and butt welded seam provides more comprehensively and protectsProtect. Use welding gun of the present invention, welding gun can be extend into apart from weld seam bottom 30mm, can meet completely to the accurate location of welding wire withProtective gas is concentrated to the requirement that is fed to solder joint.
Use welding gun and ignition tip after the utility model improves, using narrow gap technique throat thickness 30-80mm welderingWhen part, only primary standard welding gun and ignition tip need be processed, not need to lengthen (the steel plate use standard weldering below thickness 30mmSeam, in limit of consideration of the present invention). In the time using more than narrow gap technique throat thickness 80mm slab, ultra-thick plate, need be by welderingRifle and ignition tip lengthen, again processing. In practice, oblate part (ignition tip elongated portion) length can be machined to 120mm, justProperty and positioning precision are unaffected, can meet thickness 160mm with interior thick plates.
