Background technology
The platform of ship or the plank above deck are in free shrink state not closing up the stage, welded blank with it is flat
When the fillet weld on platform or deck, the free border region of plank will appear a degree of angular deformation, especially work as fillet weld seam
When form is deep penetration welding or complete penetraction and fusion in welding, multi-pass welding process will produce a large amount of heat input, and welding deformation just becomes apparent.
In the prior art, it takes some guarantor's type measures such as to increase diagonal brace before welding, to reduce angular deformation amount, but increases
The measures workload such as diagonal brace is larger, follow-up to remove diagonal brace and remain in wlding or base material on platform or deck after handling welding,
It also can expend a large amount of artificial, and such measures are only applied to free margins 200~400mm of height the case where.
Another welding manner is to take after direct welding firer to carry on the back the mode burnt to eliminate angular deformation, deforms serious situation
It is adjusted in such a way that device cooperation firer is stretched on top.But for deforming more serious angular deformation, single uses fire
The mode that the work back of the body is burnt, which is corrected, can expend a large amount of artificial, while the excessive firer of plank can also cause to damage to plate property
Wound；Device mated condition is stretched using top and needs additional assembly work post progress, the use that device is stretched on a large amount of firer and top also can be right
Free margins and platform or the paint on deck, especially ballast tank of ship protective coating generate destruction.

Platform between limiting plate 2 or deck are uneven, can influence the use of the second tooling and lifting body 10, thus be arranged bottom plate 6 with
Convenient for placing the second tooling and lifting body 10.In the present embodiment, bottom plate 6 is connect with the second limiting plate 2 and side plate 4, and is extended
To side of the straight slot 43 far from the first limiting plate 1, at this time it is not necessary that straight slot 43, the limit of the first limiting plate 1, second is arranged on bottom plate 6
Plate 2 and side plate 4 are respectively positioned on the same side of bottom plate 6.
Side of the bottom plate 6 far from the first limiting plate 1 and the second limiting plate 2 is provided with idler wheel.Idler wheel is set and is convenient for the first work
The movement of dress, is greatly saved manpower.
It is additionally provided with guidance set in first tooling and the second tooling.Guidance set can be disposed on leading on bottom plate 6
To slot and the convex block being set in the second tooling, convex block can be set in guide groove, and be slided along guide groove；Guidance set
Can be the guide groove being opened on side wall, be set to the second tooling by proximal wall side threaded hole and be sequentially connected to be oriented to
Slot and threaded hole and the bolt that can be slided relative to guide groove.Above-mentioned guidance set can make the second tooling along specific side
To sliding, the second tooling run-off the straight when in use is prevented, improves correction accuracy.
The present embodiment additionally provides a kind of bearing calibration, provides above-mentioned angular deformation means for correcting, by the freedom of workpiece 11
Side 111 is fastened between the first limiting plate 1 and the second tooling, starts lifting body 10, reduces the first limiting plate 1 and the second tooling
Between spacing with to free margins 111 carry out squeeze realize correction.
The angular deformation amount for correcting free margins 111 increases by the first limit less than or equal to lifting body 10 after preset value, is started
The spacing of plate 1 and the second tooling pushes the first tooling and the second tooling along the length direction of free margins 111, to make the first work
Dress and the second tooling are removed.
When free margins 111 is between the first limiting plate 1 and the second tooling, and between the first limiting plate 1 and the second tooling
When the sum of angular deformation amount away from thickness and free margins 111 more than free margins 111, the first tooling and the second tooling can be along freedom
The length direction on side 111 moves, and angular deformation means for correcting repeats the above process until all correction finishes by free margins 111.
The course of work of the angular deformation means for correcting of the present embodiment is as follows：
1, when the T-shaped welding of two workpiece to be welded, the first tooling is placed into one of workpiece 11 to be welded, it is flat such as ship
On platform or deck, the second tooling is placed on the bottom plate 6 of the first tooling, the free margins 111 of another workpiece 11 to be welded is folded in
Between third side plate 8 and the first side plate 41；
2, the telescopic end of lifting body 10, which is stretched out to third limiting plate 7, applies active force, and the first limiting plate 1 and third is made to limit
The spacing of position plate 7 is gradually reduced, and the angular deformation amount of free margins 111 is gradually reduced, until angular deformation amount is less than or equal to preset value,
Or completely eliminate angular deformation；
3, the telescopic end of lifting body 10 is shunk, and so that the spacing of the first limiting plate 1 and third limiting plate 7 is increased, by first
Tooling and the second tooling are moved along the length direction of free margins 111.It is straight that angular deformation means for correcting repeats above-mentioned course of work process
To all correction finishes by free margins 111, the first tooling and the second tooling are taken out.
Angular deformation means for correcting in other embodiments can be used in the manufacturing process of 50,000 tons of F type product carriers, top
Rising mechanism 10 uses load-bearing for 5 tons of oil overhold.By this device promoting the use of on 50,000 tons of F type product carriers, greatly reduce
Hot work amount is subsequently removed spent by the wlding or base material remained in after diagonal brace and processing welding on platform or deck
In working hour, the angular deformation correction man-hour of the free margins 111 per 9m long compared to that can save working hour 3h in the past, by per working hour unit price about 20
Member, at the free margins 111 about 120 of a ship 9m long, single ship makes tooling 5 altogether, every about 200 yuan of frock making cost, entirely
Ship is 6200 yuan about cost-effective, generates 12 ships within such as 1 year, then can save 7.44 ten thousand yuan every year, the installation cost is low, simultaneously
Production cost is greatly saved.
