A method and apparatus for hydraulic hochgeschwindigskeits - high-pressure shaping

摘要

The invention relates to a method for hydraulic high-speed - high-pressure shaping, in which a in an active region (27) to be formed on a blank (5) located in the hydraulic action medium (13) with a pressure pulse is loaded abruptly and the hydraulic action medium (13) the processing blank (5) is at least partially in the direction of a forming tool (6) is accelerated toward. In this case, simultaneously with the pressure pulse and / or after the pressure pulse, a hydraulic action medium (13) in such a way in the operating area (27) on the formed blank (5) and in such a manner displaced under pressure into the active region (27) is held, that the action of pressure of the working medium (13) the processing blank (5) in the effective area (27) securely on the shaping surfaces of the shaping tool (6) is applied. Likewise, a device suitable for carrying out the process stated.
