Lightweight two-crossbeam high-speed free forging hydraulic press

A lightweight two crossbeam high-speed free forging hydraulic press, comprising:

• a fixed crossbeam, for being mounted on the ground;
• a movable crossbeam, positioned above or below the fixed crossbeam, wherein an upper die is mounted on the upper one of the movable crossbeam and the fixed crossbeam, a lower die is mounted on the lower one of the movable crossbeam and the fixed crossbeam, and a through hole is provided on the movable crossbeam to serve as an oil cylinder;
• a column, provided between the movable crossbeam and the fixed crossbeam, wherein a first axial end of the column is fixedly connected to the fixed crossbeam, a second axial end of the column is provided with a first shoulder to form a sliding fit between a flared piston and the oil cylinder, and one end, close to the fixed crossbeam, of the through hole is provided with a sealing element, thus forming an annular closed oil chamber among the first shoulder, the through hole, the column and the sealing element;
• when a pressure in the annular closed oil chamber rises, hydraulic oil is able to push the movable crossbeam close to the fixed crossbeam to complete the pressing of a workpiece;
• and
• a return oil cylinder, connected between the movable crossbeam and the fixed crossbeam for driving the movable crossbeam away from the fixed crossbeam.
