U rib plate unit correcting equipment and method

The invention relates to U-rib plate unit correcting equipment which comprises a control device, a leveling device, a supporting device and a conveying device, the conveying device is used for conveying a U-rib plate unit in the first direction so as to change the position, relative to the leveling device, of the U-rib plate unit in the length direction, and the leveling device comprises an upper die, a lower die and a first driving mechanism; the lower surface of the upper die and the upper surface of the lower die correspond to the two opposite surfaces, in the thickness direction, of the U-rib plate unit correspondingly, the first driving mechanism is used for enabling the upper die and the lower die to clamp the U-rib plate unit and enabling the U-rib plate unit to be bent in the direction opposite to the bending deformation direction, and the supporting device is used for supporting the U-rib plate unit. The control device is used for controlling the leveling device, the supporting device and the conveyi
