Advantage of the present invention is:
The present invention's application reversely deformed jig frame welding procedure, welding quality and outward appearance physical dimension all meet designing requirement; Utilize reversely deformed jig frame can play the effect of welding anti-distortion, reduce distortion and the contraction of panel welding.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Detailed description of the invention
In conjunction with Figure of description, the present invention is described in more detail.
As shown in Figure 1, a kind of steel box-girder top plate unit part welding anti-distortion technique, comprises panel 1, moulding bed 2, C-type clamp tool 3, U-shaped rib 4, adjusting rod 6, bearing 7, support 8;
Described panel 1 two ends are affixed by C-type clamp tool 3 and moulding bed 2;
Described panel 1 upper weld has multiple U-shaped rib 4;
Described moulding bed 2 is connected with bearing 7 with adjusting rod 6 by support 8;
Described moulding bed 2 is made up of placenta 9, multiple cross form 5 and tyre surface 10.
Described tyre surface 10 is connected with placenta 9 by multiple cross form 5.
Described U-shaped rib 4 is arranged with cross form 5 one_to_one corresponding.
The horizontal reversible deformation of tyre surface 10 is realized by cross form 5 radian, and longitudinal reversible deformation realizes by regulating cross form 5 difference of height, horizontal and predetermined value is all transferred in longitudinal reversible deformation time, tyre surface 10 adopts gas shielded arc welding to weld with cross form 5.
The horizontal reversible deformation curvature of tyre surface 10 is about 16.1m.
Moulding bed 2 adjusts the angle of inclination of reversely deformed jig frame between 45 ° ~ 50 ° by adjusting rod 6.
U-shaped rib (4) adopts CO2 gas shield automatic vehicle to weld with the angle seam of placenta 9 and tyre surface 10; Gage of wire is 1.2mm.
Embodiment
Panel 1 thickness of the present invention and rigidity less, and U-shaped rib 4 quantity is more, and the present invention adopts 9, and correspondence is provided with 9 cross forms 5; Weld seam is intensive, and U-shaped rib 4 length is all at more than 12mm, easily produce during welding stress concentrate, welding deformation and welding shrink, and be not easy correct.Adopt and utilize level(l)ing machine to carry out machinery rectification panel 1, to eliminate distortion and remaining rolling stress.Use magnetic crane that panel 1 lifting is fixed on the reversely deformed jig frame 2 with enough rigidity; panel 1 C-type clamp tool 3 and moulding bed 2 are fixed; the horizontal reversible deformation of U-shaped rib 4 floorings is realized by moulding bed cross form 5; longitudinal reversible deformation realizes by regulating moulding bed cross form 5 difference of height; horizontal and predetermined value is all transferred in longitudinal reversible deformation time; predetermined value has engineering design side to provide, and adopts gas shielded arc welding to weld.Wherein moulding bed comprises bearing, adjusting rod 6, cross form 5, placenta 9, tyre surface 10, the formations such as set screw.The horizontal reversible deformation curvature of tyre surface 10 is about 16.1m.After U-shaped rib 4 has been assembled, adjusting rod 6 is utilized to regulate reversely deformed jig frame angle of inclination 45 ° ~ 50 ° (namely forming the welding of ship type).Welding method: U-shaped rib (4) and placenta 9, the angle seam of tyre surface 10 adopts the welding of CO2 gas shield automatic vehicle; Gage of wire is 1.2mm.The heat input produced during gas shielded automatic welding machine welding is little, is difficult to reach the requirement that U-shaped rib 4 welds rear 80% fusion penetration, and joint is more, weld appearance is shaping poor.Take to control with under type for this situation: 1) complete liquidation of U-shaped rib 4 welding bead is clean, and to polish welding bead with abrasive machine; 2) by welding tractor angle adjustment to consistent with reversely deformed jig frame 2 angle so that welding wire is deep in U-shaped rib 4 welding bead better; The method of flame heating is adopted to be corrected once produce distortion after panel 1 and U-shaped rib 4 weld.For steel plate lateral bending deformation, bake straight way along vertical rib welding direction at back of weld flame, welding residual stress is redistributed.Because steel plate two sides is heated difference, after shrinkage, deflection is different, thus reaches the object of rectification.Can on U-shaped rib 4 top for panel buckling deformation, keep at a certain distance away and bake triangle with flame, utilize triangle to cool the object reaching rectification.Utilize reversely deformed jig frame 2 to be applicable to straightway bridge floor to use.
