Abstract
Plate shears for flat workpieces, especially sheet metal, comprise a fixed lower blade (4), an upper blade (6) secured to a vertically movable blade beam (8), a cutting bench (2) arranged in front of the blades, a swivel roller bench (11) comprising several parallel rows of rollers (12) arranged behind the blades, the swivel-roller bench can be swivelled about an axis (D) substantially parallel to the cutting region of the blades and can also be moved back and forth in relation to the blades, and an adjustable stop (3) arranged behind the blades for workpieces to be cut to a given width. Swivelling of the swivel-roller bench downwardly simultaneously lowers the front of the swivel-roller bench which is closer to the lower blade.
Claims7
Plate shears for plate-shaped workpieces, in particular metal plates, comprising a stationary lower blade, an upper blade secured to a vertically movable blade beam, a cutting bench arranged in front of these blades, a tilting roller table arranged behind the blades and having several parallel rows of rollers, said tilting roller table serving to transport cut-off workpiece parts away, the table is tiltable downwardly about an axis of rotation essentially parallel to the cutting edges of said blades while also movable back and forth relative to said blades essentially perpendicular to said axis of rotation, and an adjustable stop arranged behind said blades for workpieces to be cut to a given width, characterized in that tilting of said tilting roller table (11) downwards about said axis of rotation (D) simultaneously brings about lowering of a front edge (13) of said tilting roller table (11) located close to said lower blade (4), said axis of rotation (D) of said tilting roller table (11) being located in front of said blades (4, 6) in the region of said cutting bench (2).
