| description | The invention discloses a high-precision synchronizing device for forging the moving beam of hydraulic press. The synchronizing device comprises 5 active working cylinder driving systems for realizing the active synchronous operation control, 4 balancing working cylinder systems for realizing the passive synchronous control and 2 return-stroke working cylinder systems. By acquiring the feedback signals, such as the displacement of the moving beam, the pressure and the flow rate of each working cylinder and the like, and respectively controlling the flow rate and the pressure of the liquid inlet valve groups of each active working cylinders and the liquid inlet valve groups and the liquid outlet valve groups of the passive balancing working cylinders, the active synchronous motion control of the active working cylinders, the passive synchronous control of the balancing working cylinders and the combination of the active and passive control can be realized and the synchronous operation of the moving beam is gua |
