(preparatory process)
In the groove 40 of backing plate member 11, supply with solder flux F from welding flux feeding device shown in Figure 5 26.At this moment, the 1st air hose 22a, the 2nd air hose 22b and the 3rd air hose 22c are in the state of contraction shown in Fig. 2 (b).Thereby the groove 40 of taking in solder flux F is in the state that hangs down and from truss 41 owing to the weight of solder flux F in the bottom.In addition, truss 41 is in that support plate 42 is placed on the upper end of side plate 19,19 and the state that descends.
When supplying with solder flux F, drive (the not diagrams) such as endless chains of supporting welding flux feeding device 26, one side makes welding flux feeding device 26 move along groove 40 length directions, and liner solder flux F2 and backing plate solder flux F1 that one side will be housed in the funnel scatter successively, supplies with solder flux F to backing plate member 11 (groove 40).
And, as shown in Figure 1, rely on dull and stereotyped mobile roller 105a and help roll 106 to move temporary fixed welded steel E, E, the M of bevel for welding portion that configuration is formed by welded steel E, E above pallet device 10.And allowing does not have illustrated drive unit work, carries out the width fine setting of backing plate member 11, so that groove 40 is positioned under the M of bevel for welding portion.
Specifically, broad ways moves horizontally on the backing plate roller 24a of portion on crane 24 tops being disposed to make the supporting structure 17 that is equipped with backing plate member 11, and crane 24 is configured under this supporting structure 17.
This width fine setting one finishes, and just starts magnetic means 105b, utilizes magnetic force to move welded steel E to below and fixes.At this moment, each air hose 22 and the aforementioned state that is in contraction equally.Thereby groove 40 and truss 41 are in the state of decline.
(the 1st operation)
As shown in Figure 1, drive lowering or hoisting gear 23, with the length L that keeps solder flux F and have a M of bevel for welding portion more than 2 and near the assigned position of the groove 40 of Min. length L 1 M of bevel for welding portion of welded steel E rises to welded steel E.
In the utility model, when so-called assigned position is meant and with lowering or hoisting gear 23 backing plate member 11 is risen to the rising end of groove 40, the position below 75% of diameter when the gap S of backing plate member 11 and welded steel E is the 3rd air hose 22c maximum swelling.
(the 2nd operation)
As shown in Figure 3, utilize 2 piece 3rd air hose 22cs, the 22c injecting compressed air of pressue device (not having diagram) between the top board 20 of the supporting structure 17 on support plate 42 that is configured in truss 41 and the lowering or hoisting gear 23, make its expansion.Expansion along with the 3rd air hose 22c, 22c, riser guide 21 is risen by guide rail hole 27, the 27 guiding one sides of top board 20 and base plate 18 in the 3rd air hose 22c, 22c central portion side one side, the support plate 42 hoisting depth H (with reference to Fig. 2 (b)) of riser guide 21 upper ends, whole truss 41 lifting height H will be fixed on.
And the expansion of the 3rd air hose 22c is performed until base plate 18 lower surfaces that the block 21c that is arranged on riser guide 21 bottoms abuts to supporting structure 17.At this moment,, rise simultaneously with groove bearing support 41a, 41a and the groove 40 of support plate 42 one along with the lifting of support plate 42, the upper end of groove 40 rise near or the position of the M of the bevel for welding portion dorsal part of butt welded steel E.
That is to say that the solder flux F amount in being accommodated in groove 40 is lacked a little, in the time of can not swelling from groove 40, the upper end of groove 40 rises to against the position of the M of bevel for welding portion dorsal part.
In addition, the solder flux F amount in being accommodated in groove 40 is more a little, and when protuberance was a lot of from groove 40, the upper end of groove 40 rose to the position near the M of the bevel for welding portion dorsal part of welded steel E, becomes the state that backing plate solder flux F1 is pressed on the M of bevel for welding portion dorsal part.
(the 3rd operation)
Utilize pressue device (not diagram) to import air, the 1st air hose 22a is expanded to the 1st air hose 22a.Expansion along with the 1st air hose 22a that is configured in groove 40 downsides, the bottom of taking in the groove 40 of solder flux F is raised, solder flux F is risen to the height of contact welded steel E fully, and solder flux F is resisted against the dorsal part of the M of bevel for welding portion of welded steel E with suitable extruding force.
(the 4th operation)
Then, as shown in Figure 7, one side moves welding machine 30 with fixing speed on welding machine crossbeam 101, and one side utilizes welding torch 33 to implement single-sided welding from the M of bevel for welding portion face side, welding welded steel E, E.
Next, when a plurality of bevel for welding M of portion, discharge the air in the 1st air hose 22a and the 3rd air hose 22c, fall riser guide 21, support plate 42 and groove 40, solder flux F is drawn back from welded steel E dorsal part.Then, fall crane 24, backing plate member 11 is descended from welded steel E dorsal part, backing plate solder flux F1 is drawn back from the welded steel E back side with lowering or hoisting gear 23.Next, the backing plate solder flux F1 that carries out groove 40 upper surfaces used the removal of part, then, drove (the not diagrams) such as endless chains that link to each other with described welding flux feeding device 26, carried out the supply of new backing plate solder flux F1 to groove 40 upper surfaces.Then, finely tune (carrying out preparatory process),, carry out described the 1st～the 4th operation so that solder flux F and groove 40 are positioned under the next bevel for welding M of portion.Repeatedly carry out such action, disappear until the M of bevel for welding portion.
(reclaiming the situation of solder flux)
Also have, after welding with welding machine 30, backing plate solder flux F1 is owing to welding heat solidifies.Then, in order to weld next time, must remove the backing plate solder flux F1 of curing, the upper strata in groove 40 replenishes new backing plate solder flux F1.At this moment, the liner solder flux F2 use of keeping intact stays liner solder flux F2 for well as far as possible when therefore removing the backing plate solder flux F1 that solidifies.
Also have, in order to remove the backing plate solder flux F1 that solidifies from groove 40, the 1st air hose 22a is expanded, F1 sweeps with its backing plate solder flux, but, sometimes a large amount of liner solder flux F2 is swept together.In addition, in order to prevent this unreasonable situation, the method of considering is not make the 1st air hose 22a complete expansion, and only expand about half, but, the degree that this moment, the 1st air hose 22a expanded be certain on total length, the position that often produces the backing plate solder flux F1 that can not fully reclaim curing and the position of sweeping a large amount of liner solder flux F2 etc.
So, as shown in Figure 4, using the solder flux F in the 2nd air hose 22b upgrading slot 40, the 2nd air hose 22b can evenly promote the solder flux F in the groove 40 with the lifting amplitude of the 1st air hose 22a about half across groove 40 total length L1.
To the situation that the used backing plate solder flux F1 that solidifies reclaims, utilizing lowering or hoisting gear 23 decline truss 41, after the space of groove 40 top belays regulation, carry out.This situation, as shown in Figure 4, be to shrink the 1st air hose 22a and the 3rd air hose 22c, 22c, descend under the state of whole truss 41, transmit compressed air from pressue device (not having diagram) to the 2nd air hose 22b, make the 2nd air hose 22b expand, make solder flux F to rise and carry out afterwards.
When reclaiming these solder flux F, use groove 40, truss the 41, the 2nd air hose 22b and the supporting structure 17 of flux collection system 25, backing plate member 11.
In this case, as shown in Figure 4, thereby used backing plate solder flux F1 becomes the state at groove 40 upper surfaces protuberance along with the 2nd air hose 22b expands, the solder flux that utilization is attached to welding flux feeding device 26 is swept device (not diagram) and is swept its bump, sweep after backing plate solder flux F1 surface becomes certain altitude, utilize welding flux feeding device 26 to scatter new backing plate solder flux F1 and replenish.Sweeping the solder flux F that falls utilizes flux collection system 25 to reclaim.
The solder flux F that solidifies discharges compressed air from the 2nd air hose 22b after reclaiming and finishing, and becomes the state of contraction.Consequently in groove 40, produce and the suitable hole of solder flux F of removing, therefore utilize these parts of 26 pairs of grooves 40 of welding flux feeding device to supply with new backing plate solder flux F1.Also have, liner solder flux F2 can not solidify by soldered heat, therefore can reuse.
More than, be illustrated about embodiment of the present utility model, but, the utility model is not limited to described embodiment, and change can suit in the scope that does not break away from the utility model aim.
