7, 28 are cylinders 33, 3 on mounting bases 29, 30.
4, and the movable pedestals 27 and 28 are moved up and down by the operation of the cylinders 33 and 34. Moreover, among the movable pedestals 27 and 28 facing each other,
One movable pedestal 27 is provided with a reference contact surface 35 that contacts the widthwise contact surface of the frame 5, and the other movable pedestal 28 is provided with a ram 36 to position the frame 5 in the width direction. ing. Also,
A reference contact surface 3 that contacts a reference surface in the longitudinal direction of the frame 5 is provided on one side of the movable pedestals 27 and 28 in the front and back direction.
7 is provided, and a ram 38 is provided on the other side to position the frame 5 in the longitudinal direction.

By making the bending guide centering frame 7 have the above-described structure, when servicing the bending guide 1, first,
Lay down the reference side frame 4 sideways with the reference side frame 4 on the bottom, place the frame 4 on the fixed pedestals 8, 10, 11 and the reference stands 20, 21, support the center part and both ends of the frame 4 in the longitudinal direction, and place it on the platform. Determine the After being placed on the rack, the profile is kept constant by determining the longitudinal direction, so the ram 15 is operated to push the contact surface of the frame 4 into contact with the reference contact surface 12. Thereafter, in order to correct the torsion in the longitudinal direction, the widthwise positioning ram 19 is operated to contact the reference contact surface 20a, thereby positioning and supporting the frame 4 in the longitudinal and widthwise directions. ing. Next, in order to support the upper frame 5, the mounting bases 29 and 30 are attached to the cylinders 31 and 30, respectively.
32 is driven to move close to the position below the upper frame 5, and then the cylinders 33 and 34 are driven to raise the movable pedestals 27 and 28 to support the lower surface of the frame 5. Thereafter, similarly to the lower frame 4, the ram 38 is actuated to bring the reference surface of the frame 5 into contact with the reference contact surface 37, and then the ram 36 is actuated to bring the reference surface of the frame 5 into contact with the reference abutment surface 35. It is positioned and supported by bringing the surfaces into contact. In this way, after supporting the upper frame 5, the bending guide 1
To disassemble it, remove the side plate 6 and separate the frames 4 and 5. After being disassembled, the frame 5 on the opposite reference side cannot be maintained unless it is inverted, so it is moved to an inversion mount (not shown) and the roll maintenance is performed. Roll maintenance is performed while the frame 4 is placed on the centering frame 7. After arranging the rolls on the reversing stand, move the frame 5 to the centering stand 7, and move the frame 5 to the movable stand 27, 28.
