Arrangement of a hydraulic circuit, in particular of a press, for the hydromechanical drawing of sheet in a pressure chamber

摘要

The invention relates to an arrangement of a hydraulic circuit, in particular of a press, for the hydromechanical drawing of sheet in a pressure chamber, whose space filled with fluid is connected to a transducer system containing at least one piston transducer. The object of the invention is to simplify the arrangement, while increasing the range of use, and to use standard parts. The invention achieves the object by a hydraulic/mechanical transducer being attached to the side of the larger piston diameter of a piston transducer of the transducer system, which hydraulic/mechanical transducer is mechanically connected to a mechanical/hydraulic transducer, the hydraulic outlet (16) of which is connected at least via a non-return valve to the main space of the working cylinder of the press. <IMAGE>
