US 6,009,783 A · Method in a sheet metal work center and a sheet metal work center

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. Working operations of the lower tool are conducted with the locking arrangement released and a part of the transfer device used, and the releaser being kept at its position by a second part of the transfer device.
