整装置。 Each of the power generator and the hydraulic press is provided with a position detector that detects the current position of the slide that is constantly in operation, and the pressurizing circuit from the power generator to the hydraulic press is connected via a supply/discharge switching solenoid valve. A hydraulic pump for adjusting the position of the press slide is connected to the press slide, and an amount of pressurized oil is supplied to the pressurizing circuit, and signals from both position detectors are subtracted so that the press slide is synchronized with the slide of the power generator. A slide position adjustment device for a power generator-driven press, characterized in that the obtained control signal is used to perform adjustment control using the supply/discharge switching solenoid valve.
