  • Hydraulic arrangement for performing a secondary operation in a pressing tool for sheet metal forming
    Patent number: 6279370
    Abstract: The invention relates to an arrangement for performing a secondary operation in a pressing tool for sheet metal forming comprising a primary cylinder/piston unit (1) arranged to pressurise an operating fluid upon closing of said pressing tool for performing a primary forming operation on a work piece. A secondary cylinder/piston unit (7) is mounted within said pressing tool, carrying tooling for conducting said secondary operation mounted on its piston rod (7c). The arrangement further comprises means (2, 20, 21) for storing said pressurised operating fluid and means for selectively allowing a first volume flow of operating fluid of a first pressure to the secondary cylinder/piston unit (7), for advancing its piston rod (7c) until the tooling encounters the work piece.
