プレス機械。 A hydraulic cylinder is installed in the slide part of the press machine that moves up and down with the rotation of the crankshaft.
The press machine is equipped with a striker that presses the upper die against the cylinder or piston of the hydraulic cylinder, and when the striker strikes the upper die and punches the workpiece, the pressure increases in the hydraulic chamber of the hydraulic cylinder. A press machine, characterized in that an oil supply circuit and an oil drain circuit are connected, an accumulator is provided in the oil supply circuit, and a check valve biased in the closing direction is provided in the oil drain circuit.
