Abstract
The invention relates to a hydraulic drive device (11) with at least one press cylinder, in particular a press synchronous cylinder, for a hydraulic press, preferably a powder press (10), wherein the hydraulic drive device is configured to guide a cylinder piston of the press cylinder in a rapid movement at increased speed towards a pressed part and to press the pressed part in a pressing movement at low speed, wherein the drive device comprises a switching valve (17), a controllable pressing movement pump (15), in particular a speed-controllable pressing movement pump (15) for conveying fluid for the pressing movement and a control unit (28) for controlling the pressing movement pump (15), wherein the drive device is configured to perform the rapid movement when the switching valve (17) is open and to perform the pressing movement when the switching valve (17) is closed, wherein the control unit (28) is configured to control the pressing movement pump (15) in such a way that a conveyance rate of the pressing movement pump (15) is already increased before the closing of the switching valve (17).
