The method disclosed by the invention comprises normal position assembly of aluminum alloy sections, normal position welding and anti-position welding. The method disclosed by the invention is easy to operate, and welding of multiple aluminum alloy sections is completed rapidly and efficiently on the premise of ensuring the welding quality.
Description
Technical field
The present invention relates to a kind of method that prevents the distortion of polylith aluminium alloy extrusions Combination Welding, belong to the materials processing technology field.
Background technology
Aluminium alloy be take the alloy general name that aluminium is base, and main alloy element has copper, silicon, magnesium, zinc, manganese, and less important alloying element has nickel, iron, titanium, chromium, lithium etc.Aluminium alloy density is low, but strength ratio is higher, approaches or surpasses the high-quality steel, and plasticity is good, can be processed into various section bars, has good electric conductivity, thermal conductivity and corrosion stability, make its in the high ferro industry by rapidly, adopt widely.
Solder technology is divided into two parts usually: the one, in order to guarantee the skill operation technology of weldquality; The 2nd, reach for making welding product the welding technique that instructions for use is taked.
The solder technology of aluminium alloy started from external introduction in eighties of last century late nineteen nineties, the special physical property that it exists self due to aluminium alloy, cause it after welding, can produce larger distortion, thereby affect the installation of subsequent product, especially in the locomotive industry, (many reaches seven) that base plate generally is comprised of the polylith section bar, numerous weld seams produce complex stresses, make parts produce larger torsional deformation, bring difficulty to rear channel correction operation.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that prevents the distortion of polylith aluminium alloy extrusions Combination Welding, and the inventive method behaviour does simple, under the prerequisite that guarantees weldquality, completes fast and efficiently the welding of polylith aluminium alloy extrusions.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of method that prevents the distortion of polylith aluminium alloy extrusions Combination Welding comprises:
1) aluminium alloy extrusions normotopia assembling: the aluminium alloy extrusions of polylith being held successfully to groove is successively placed on the cushion block of frock, pneumatic gripping on the frock two ends compresses above-mentioned aluminium alloy extrusions to centre, butt weld two ends between aluminium alloy extrusions add run-on tab and arc-extinguishing plate, from the run-on tab end of butt weld to the arc-extinguishing plate end every the intermittent weld of 1 meter welding 50～60mm;
2) normotopia welding: first weld the weld seam in the middle of being positioned at automatic welding device, then, successively to the weld seam welding of both sides, obtain the complete aluminium alloy extrusions jigsaw of single-sided welding;
3) antiposition welding: before the antiposition welding, add aluminium block on cushion block in the middle of being positioned at below weld seam, by 2) the aluminium alloy extrusions jigsaw that makes stands up, the pneumatic clamping device that recruitment is loaded onto by the aluminium alloy extrusions jointed board clamp to the cushion block plane of frock, weld seam in the middle of first welding is positioned at, successively to the weld seam welding of both sides, obtain again.
Mold when frock is the aluminium alloy extrusions welding, distortion while controlling the section bar welding, the main role of frock in the normotopia welding: make the chain of command of part at grade, prevent from misplacing between aluminium alloy extrusions; The part distortion caused during the control section weldering; Be convenient to install run-on tab and receive the arc plate; Make the polylith aluminium alloy extrusions form an integral body on frock;
The invention has the beneficial effects as follows: the inventive method behaviour does simple, under the prerequisite that guarantees weldquality, complete fast and efficiently the welding of polylith aluminium alloy extrusions, effectively solve this complicated problem of plate class welding deformation formed by the polylith aluminium alloy extrusions, be specially adapted to the base plate welding of high ferro.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the size of described run-on tab and arc-extinguishing plate can be adjusted according to different products, and as run-on tab is 40～50mm with the length of receiving the arc plate, thickness is identical with aluminium alloy extrusions.
Adopt this further improved beneficial effect to be: the one, to aluminium alloy extrusions heat conduction, the 2nd, play the fixedly effect of aluminium alloy extrusions, the 3rd, the defect of elimination starting the arc end;
Further, the thickness of described aluminium block is 15～60mm.
Adopt this further improved beneficial effect to be: the anti-deformation that reserves the aluminium alloy extrusions jigsaw;
Further, the plane clearance that the aluminium alloy extrusions jigsaw after described welding is measured optional position with the leveling ruler of 1 meter is 2～4mm.
The accompanying drawing explanation
Fig. 1 is aluminium alloy extrusions normotopia welding schematic diagram of the present invention;
Fig. 2 is aluminium alloy extrusions antiposition welding schematic diagram of the present invention;
In figure, the list of parts of each label representative is as follows:
1, aluminium alloy extrusions, 2, cushion block, 3, pneumatic gripping, 4, frock, 5, aluminium block.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
Embodiment 1
As shown in Figure 1, a kind of method that prevents the distortion of polylith aluminium alloy extrusions Combination Welding comprises:
1) aluminium alloy extrusions normotopia assembling: 7 aluminium alloy extrusions 1(are had to groove) be successively placed on the cushion block 2 of frock 4, pneumatic gripping 3 on the frock two ends compresses above-mentioned aluminium alloy extrusions 1 to centre, butt weld two ends between aluminium alloy extrusions add run-on tab and arc-extinguishing plate, the length of run-on tab and receipts arc plate is 40～50mm, thickness is identical with aluminium alloy extrusions, from butt weld run-on tab end to the arc-extinguishing plate end every 1 meter the welding 50～60mm intermittent weld;
2) normotopia welding: first weld the weld seam in the middle of being positioned at two welding guns of automatic welding device, then, successively to the weld seam welding of both sides, obtain the complete aluminium alloy extrusions jigsaw of single-sided welding;
3) antiposition welding: before the antiposition welding, add the aluminium block 5 that thickness is 40mm on cushion block 2 in the middle of being positioned at below weld seam, by 2) the aluminium alloy extrusions jigsaw that makes stands up, the pneumatic clamping device 3 that recruitment is loaded onto by aluminium alloy extrusions jigsaw clamping to cushion block 2 planes of frock, weld seam in the middle of first welding is positioned at, successively to the weld seam welding of both sides, obtain again.
