Utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, easy to operate, use web preventing deformation apparatus for correcting flexibly, can solve distortion increase, the deformed region that web amount of localized heat is gathered, temperature raises to be produced and increase problem, applied widely, highly versatile.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of web preventing deformation apparatus for correcting, comprise one group of constraint floor and the heating unit being arranged in parallel that is vertically laid in the protruding distorted area of web, the side contacting with web on described constraint floor is provided with groove.
Described constraint floor is equally distributed on the protruding distorted area of web, and groove corresponding on described constraint floor is arranged in a linear.
Distance between described constraint floor is 150-200 mm.
The length of described constraint floor is greater than the length of protruding distorted area, and its thickness is 10-20 mm, and width is 150-250 mm.
Groove on described constraint floor is more than 3, and spacing equates.
Described groove is U-shaped structure, its slot opening 20-40 mm, the high 20-40 mm of groove.
Distance between described groove is 150-250 mm, and the groove that is positioned at two ends is 50-150 mm apart from the distance on constraint floor both sides.
Described heating unit is jetting-sucking welding torch.
The model of described jetting-sucking welding torch is H01-40.
The beneficial effect that adopts technique scheme to produce is: the utility model arranges constraint floor in the protruding distorted area of web, protruding distorted area is heated with heating unit, raise with temperature, welding stress is redistributed, constraint floor plays restraining effect to distortion, can correct protruding distorted area fast, effectively solve distortion increase, the deformed region that web amount of localized heat is gathered, temperature raises to be produced and increase problem.The quantity of the constraint floor in the utility model and size can be laid according to the size of protruding distorted area area, simple in structure, easy to operate, use flexibly, applied widely, highly versatile.
