The design and analysis of the 2000 t hydraulic forging press' hydraulic system theory was introduced. The directional valve and unloading valve of the hydraulic system respectively adopted proportion throttle cartridge valve and proportion spillover valve. Electron-amplifier controlled the electric current inputting proportion electromagnet,the valve port and the direction of fluid stream. By the way of adjusting the raising and descending time of slope regulation resistance electric current,the conversion time of reversal valve' inverting,unloading speed was controled and utilizing the hydraulic-electric combination advantage,the machine worked smoothly and fast.
