A hydraulic forging press comprises a frame made in the form of upper and lower fixed crossbars rigidly connected by vertical columns, a movable crossarm mounted on the columns and three vertical working cylinders placed in the holes of upper crossbar, which rest by lower flanges on the lower plane of upper crossbar and interact with the crossarm. The side working cylinders are made with double cavities to form in each of them working and reverse cavities. The total active area of the working cavities of the side hydraulic cylinders is less than the active area of the central hydraulic cylinder. |
