Abstract
The invention relates to a method used for double-curved-surface water and fire curved shape correction, and belongs to the field of plate material shape correction. The method comprises the following specific steps that 1) a heating point is positioned at a place of a bottom plate, which is 350-450mm far away from a top plate, heating is started from the heating point to the center of a bridge bottom, the heating distance is 2750-2850mm, the interval is 800-1000mm, water is simultaneously used for cooling in the heating process, the distance between the water and fire is 120-150mm, and the heating temperature is 700-1000DEG C; 2) for the heating of a first radian 1, a heating source is positioned on one side of the structureless surface of a box beam structure bottom plate; and for the heating of a second radian 2, the heating source is positioned on one side of a structural surface of the box beam structure bottom plate. The method has the beneficial effects that the method used for hot working cold shape correction is suitable for manufacturing a large steel structure double-curved product. The method is simple, the time and the cost are saved, the economic benefit is improved, and the integral appearance quality is good.
Description
Technical fieldThe present invention relates to belong to the orthopedic field of sheet material for the curved orthopedic method of hyperboloid extreme misery.
Background technologyFish belly hyperbolic type bridge, specious generous because of it, more and more be applied to such as in the middle of the public buildings such as railway station, fish belly hyperbolic type bridge, bridge is wide 10.2 meters, 2.2 meters of case depth of beams, 64 meters of the curvature of centre radiuses of bridge, require the outward appearance of bridge not allow obvious broken line, base plate thickness reaches 20mm-32mm, and the hyperbolic of slab is the difficult point of making.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this invention is to provide a kind of method simple, save cost, the effective curved orthopedic method of hyperboloid extreme misery that is used for.
For achieving the above object, the technology used in the present invention solution is: be used for the curved orthopedic method of hyperboloid extreme misery, its concrete grammar is as follows: 1, hot spot is positioned at base plate apart from top board 350mm-450mm place, the center begins heating at the bottom of from this point to bridge, the heating distance is 2750mm-2850mm, and spacing is 800mm-1000mm, uses simultaneously water cooling in the heating process, extreme misery is apart between the 120mm-150mm, 700 ℃-1000 ℃ of heating-up temperatures; 2, for the heating of the first radian 1, heating source is positioned at non-structure face one side of box-beam structure base plate, heating for the second radian 2, what heating source was positioned at the box-beam structure base plate has structural plane one side, the first radian 1, the second radian 2 are heated by the center, interior lateral of bridge respectively, spacing is 400mm, and every side has four hot spots at least.
Be used for the curved orthopedic method of hyperboloid extreme misery, its beneficial effect is: this firer water-cooled straightening method is applicable to the making of large-scale steel structure hyperbolic type product, and the method is simple, save time, save cost, increase economic efficiency, the overall appearance quality is good.
