DEVICE FOR ACTUATION OF METAL-FORMING MACHINES (VERSIONS), METHOD OF ACTUATION OF METAL-FORMING MACHINES AND CONTROL SYSTEM OF METAL-FORMING MACHINES Russian patent published in 2013 - IPC F15B3/00 B30B15/16

Abstract RU 2472977 C2

FIELD: machine building.

SUBSTANCE: metal-forming machine is actuated by at least two generators (1, 2) of pressure by means of fluid medium under pressure similar to water, while pressure generators are actuated by pumps (31-33) with controlled efficiency by means of another fluid medium under pressure, for example liquid for hydraulic systems.

EFFECT: simplifying design, reducing energy consumption.
