| Abstract: | 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-amplifler 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 regula-tion resistance electric current, the conversion time of reversal valve' inverting, unloading speed was controled and uti-lizing the hydraulic-electric combination advantage, the machine worked smoothly and fast. |
