Abstract

PURPOSE: To perform necessary hydraulic operation purely in the operation of a pressing machine by a fluid control circuit adapted for the machine.
CONSTITUTION: When an electromagnetic directional control valve 4 is switched to left position, hydraulic oil from a variable pump 1 is supplied to the left chamber of an actuator 6 and hydraulic oil from the right chamber is returned through a directional control valve 5 into a tank 30b to finally approach a ram to the vicinity of a work W to be formed at high speed. When the valve 5 is then switched by a cam 40 to allow the oil in the right chamber to pass through a flow control unit 36, the ram is decelerated immediately before making contact with the work W. When the ram and accordingly the rod 6a makes contact with the work W, the pressure of a main line 28 is increased to press the work W. When the spool 14 is moved rightwardly upon increase of the pressure, the discharged oil from the pump 1 is partially introduced into a control cylinder 11 as designated by a broken line with an arrow, and the rod 6a is stopped at the end.
