Abstract
PURPOSE: To enable the press to be used for not only high speed interlock but manual operation as well and make possible accurate high speed interlock by separating and integrating the hydraulic circuits of the press to two circuit systems for manual operation and high speed interlock.
CONSTITUTION: In the A lines 1, 2 of the hydraulic circuit A for manual operation, the pressure oil from a main pump Al is alternately supplied to the chambers (a) and (b) of a cylinder 1 from a branching solenoid changeover valve A2 via manual operating solenoid changeover valve A3, thereby causing a piston 2 to make reciprocating motion. An auxiliary hydraulic pump Bl is not in operation and the pressure in an accumulator B2 is zero. Shutoff solenoid changeover valves B3 and B10 are blocking the reverse flow of the pressure oil from the A line 1, 2 sides to the push side circuit B line 1 for high speed interlock and lift pressure side circuit B line 2 with their port blocks A, T. In the B line 1, the pressure oil discharged from the main pump A1 goes through the solenoid changeover valve B4 from the B port of the valve A2 and is supplied to the (a) chamber of the cylinder 1 or discharged through the A port of the changeover valve B10.
