の安全油圧制御回路。A hydraulic control circuit for a hydraulic press that performs press forming by connecting a hydraulic switching valve for actuator operation to a pressurizing cylinder for press forming of a hydraulic press & 5, a hydraulic circuit on the forward side for press forming of a pressurizing cylinder. A pressure relief circuit is connected to the IJ IJ-F valve using a remote control valve that operates when the pressurizing cylinder moves backward to freely control pressure reduction, and the hydraulic switching valve for actuator operation controls the forward movement of the pressurizing cylinder. A pilot piston cylinder device is installed at the end of the hydraulic switching valve to suppress switching of the spool of the hydraulic switching valve by pressing it with an internal piston until the hydraulic circuit on the forward side reduces the pressure to a constant pressure. The hydraulic circuit on the forward side of the pressurized cylinder is equipped with the pressure relief circuit so that the pressure in the hydraulic circuit on the forward side can be returned to a constant reduced pressure, and the piston is installed inside the pressurized cylinder, so that the pressure in the hydraulic circuit on the forward side can be freely operated. A safe hydraulic control circuit for a hydraulic press, characterized in that it is formed by connecting a pilot pressure introduction hole with a piping.
