MULTIPLE-HEAD FORGING FACILITY Russian patent published in 2009 - IPC B21J13/02 B21J7/16 

FIELD: metallurgy.

SUBSTANCE: facility contains holders of top and bottom heads and two holders of side heads. To holders there are affixed corresponding heads. Heads, fixed to holders, located in one of two mutually perpendicular planes, allows two operating sections. These sections are located from the each side of facility plane of symmetry. Heads, fixed to holders, located in the different plane, allows one operating section each. Current operating section can be located between mentioned two operating sections. In facility there is at least one system for movement at least one head relative to its holder. System contains hydraulic actuator with rod or plunger and control system, hydraulic actuator and facility position measuring of head relative to its holder. Head is connected to rod or plunger of hydraulic actuator with ability of fixed movement relative to corresponding holder in vertical or horizontal symmetry plane of facility. Hydraulic actuators are located in bodies of corresponding holders of heads. In pipelines of operating fluid supply to hydraulic actuators there are built in back pressure valves.

EFFECT: laboriousness reduction of facility repurposing for different dimension type.
