  • Sheet metal work center with a movable lower die operative as a stopper and an upwards forming tool
    Patent number: 6408726
    Abstract: The invention relates to a sheet metal work center whose lower tool is mounted in a transfer device which is movable in the vertical direction in relation to the body in a way that the lower tool can optionally be moved by the transfer device to at least the following selectable positions in relation to the body: a) a lower position, whereat the lower tool is substantially accessible underneath the working level, particularly for exchange and/or maintenance operations, b) a middle position, whereat the lower tool is brought substantially to the working level to be used as a stopper for the upper tool to effect work on the sheet, and c) an upper position, whereat the lower tool is driven underneath the working level to conduct work on the lower surface of the sheet.

  • Method in a sheet metal work center and a sheet metal work center
    Patent number: 6009783
    Abstract: The invention relates to a sheet metal work center and a method for fabricating sheet metal therefrom. In the sheet metal work center, a locking arrangement is placed between the upper tool and a releaser, and the transfer device is arranged to consist of two parts. The sheet metal work center is adaptable to work in either a passive or active mode. In the passive mode, the releaser is positioned at a certain distance from the surface of the sheet, and the movements of the upper tool and the releaser are made with the locking arrangement locked and either part of the transfer device used. In the active mode, the releaser is positioned to be in contact with the sheet, and the movements of the upper tool and releaser are made with the locking arrangement locked and either part of the transfer device used.
