The centering hydraulic cylinder 4 drives the side push plate 5, and the centering synchronization unit drives the two side push plates 5 to synchronously approach and center / clamp the rolled plate, or synchronously move away and release the rolled plate. The guide unit plays a guiding role during the movement of the side push plate 5.
[0019] Each guide unit includes two guide rods 9. Guide rod supports 15 are symmetrically arranged on the clamping support 2.

One end of the guide rod 9 is fixed to the side push plate 5 through the connecting plate 8. The guide rods 9 can move within the guide sleeves 19, thus playing a guiding role when the side push plate 5 moves.
[0020] The centering synchronization unit includes two synchronizing links 16, which are symmetrically arranged along the centering cylinder 4. The synchronizing links 16 are horizontally threaded through the push plates 5 on both sides.

When the centering cylinder 4, located on the side of the central gear assembly, drives the corresponding side push plate 5 and guide rod 9 to move along the guide sleeve 19, under the action of the first straight rack and the central gear assembly, it drives the arm, synchronous connecting rod, connecting arm, another guide rod, and the other side push plate to move in the opposite direction, so as to realize the symmetrical movement of the two push seats towards the center, to center and clamp the rolling plate, and conversely, to release the rolling plate.
[0021] like Figure 4 As shown, each central gear assembly includes a gear seat 12, a gear shaft 18 on the top of the gear seat, a central gear 17 mounted on the gear shaft 18, and a bearing connecting the central gear 17 and the gear shaft 18.
