Abstract

PURPOSE: To set balance pressure for balancing the weight of a slide adequately in a short time, by detecting air pressure which corresponds to the weight of a top force by adjusting the air pressure in a press machine.
CONSTITUTION: Air pressure for a balance cylinder 8 and the discharge-side pressure of a pump 26 are set to maximum. A piston rod 10 is drawn up and a detector 25 turns on. A relief valve 20 is controlled by a solenoid valve 21 and a lock device 12 is operated by a pump 19 to lock the piston rod 10. Further, a relief valve 27 is controlled to decrease the hydraulic pressure of a detection cylinder 23 gradually. Pressing-up force for a slide 4 by hydraulic pressure when the slide 4 moves down to turn on the detector 25 exerts desired balancing force. Air pressure which generates this pressing-up force is calculated and regulator valve is set by a servomotor. After air pressure adjustment, the lock mechanism 12 is released and press operation is carried out without supplying the pressurized oil of a detecting mechanism 13.
