VACUUM PRESS Russian patent published in 2016 - IPC B22F3/15 F27D1/18 

FIELD: technological processes.

SUBSTANCE: invention relates to equipment for deformation, welding and sintering powder articles in vacuum, in a gas medium with low excess pressure and at high pressure of gases and high temperature. Proposed press comprises high-pressure compactions and series-arranged behind them vacuum seals arranged at connection points of: the housing with plugs and the male die, the gate with the plug, inspection openings and current leads with the movable plug. Besides, it is equipped with a cylinder for moving the plug fixed on the base of the bed. Its heat insulating chamber, the heater and the table are fixed on the movable plug, herewith the heat insulating chamber is equipped with tightly arranged transparent windows and gas feed tubes. In the heat insulating chamber there is a hole for passage of the male die equipped with a centering ring movable in the radial direction, installed on the chamber and preventing the heated gas outlet into the gap between the male die and the chamber. End of the male die is attached with a hammer isolated from the male die with intermediate gaskets and a heat clearance.

EFFECT: provided is the press operation at the gas pressure up to 10 MPa and its reliability.
