Background

With the rapid development of the steel structure market, strict regulations are made on the quality requirements of steel structure products; under the condition that the society knows steel structure products more and more fully, the requirement of steel structure engineering quality is higher and higher. In the welding and heating process of the formed I-shaped steel or H-shaped steel, the wing plates generate angular deformation due to the transverse shrinkage of weld metal. In the aspects of heavy steel production, BOX BOX beam manufacturing, butt joint of section steel and the like, the requirement of flatness of section steel wing plates is a consensus of a plurality of manufacturers in China. For the structural characteristics of the T-shaped steel and the H-shaped steel, special equipment for correcting the post-welding angular deformation of the wing plate is needed. For certain workpieces, conventional fixed corrective devices may be sufficient. However, for workpieces of variable width and long length, the requirements cannot be met with conventional straightening equipment, which requires flexible, adjustable straightening machines. The bed device of the straightening machine used in the current market usually adopts a fixed base and is adjusted by bolts. The base of the structure can not move, so that when the structure faces workpieces with different widths, the position of the driving roller is completely adjusted by the bolt, the application range is not flexible enough, and the adjustment is troublesome.
