Three-axis coordinated control device of hydraulic system of powder pressing machine

The utility model provides a three-axis coordinated control device of a hydraulic system of a powder pressing machine. The three-axis coordinated control device comprises a hydraulic drive unit, a control unit, pressure sensors and position encoders; the control unit acquires current movement position and current oil pressure of the hydraulic system; the pressure sensors detect current oil pressure of oil cylinders; the position encoders detect the current movement position of the hydraulic system; when a difference between the current movement position and the extreme movement position of the hydraulic system is smaller than a position set value and when a difference between the current oil pressure and the reference oil pressure is smaller than a pressure set value, the control unit controls the hydraulic system to stop moving. The problem that the hydraulic system is often low in accuracy and incapable of performing multi-axis simultaneous operation is solved.
