Preferably, the upper workbench is further fixedly connected with a guide block, and the guide block penetrates through and is connected to the connecting plate in a sliding manner.

Preferably, a piston rod of the hydraulic oil cylinder is fixedly connected with the upper workbench through a connecting flange.

Preferably, the upright post is fixedly connected with the hydraulic oil cylinder through a bolt.

Preferably, the side surface of the upright post is of a C-shaped structure.

Compared with the prior art, the utility model has the beneficial effects that: the device is provided with the hydraulic oil cylinder, the connecting plate, the upper workbench, the stand columns and the lower workbench which are matched with each other, a workpiece is placed on the lower workbench, the distance between the two stand columns can be widely set, and the workpiece can be horizontally placed or vertically placed, so that the device is suitable for the shaping work of large workpieces; and the equipment investment cost is lower than that of a four-column press, the use cost is saved, and the maintenance is simple.
