Torsion shaft synchronization regulation device for hydraulic sheet metal torsion shaft bending machine

The utility model discloses a torsion shaft synchronization regulation device for a hydraulic sheet metal torsion shaft bending machine. The device comprises a synchronizing torsion shaft rotatably installed on the inner side of the upright post of a frame and a slipper connected with the piston rod of an oil cylinder. The torsion shaft synchronization regulation device is characterized in that swinging arms are fixedly connected with the two sides of the synchronizing torsion shaft respectively, a crossbeam is fixedly welded at the lower end of the inner side of the slipper, a base is fixedly arranged on the crossbeam, a vertical link rod is fixedly arranged on the base, and the top end of the link rod is movably hinged with the lower ends of the swinging arms. The torsion shaft synchronization regulation device utilizes the torsion of the synchronizing torsion shaft to realize the synchronized motion of the two ends of the synchronizing torsion shaft, and satisfies the requirements for regulating the balance performance of the torsion shaft bending machine.
