The invention discloses a rapid forging press servo direct-drive hydraulic system, and belongs to the field of rapid forging press hydraulic transmission control. The rapid forging press servo direct-drive hydraulic system mainly comprises a main cylinder, a bidirectional quantitative pump, a servo motor, an overflow valve, a one-way valve, a hydraulic pipeline, a rodless cavity and a rod cavity of a main press cylinder and the like, an oil outlet and an oil inlet of the bidirectional quantitative pump are connected to the rodless cavity and the rod cavity respectively, the servo motor directly drives the bidirectional quantitative pump to run, a hydraulic actuating mechanism is directly driven by a servo motor and quantitative pump set so that a press continuously runs, the servo direct-drive hydraulic system controls the motor instead of controlling a control object (the valve or pump) in an original press hydraulic system, and the operating mode of the motor is improved into an intermittent ...
