Device for transversally cutting a rolled strip
View Patent ↗The invention relates to a device for transversally cutting a rolled strip using shears, especially drum shears. According to the invention, a gap between the end of the roller table upstream of the shears and the beginning of the roller table downstream of the shears, where there is no support for the rolled strip, is reduced by a pivotable roller table part supporting the rolled strip as it passes through, and a mobile guiding table is arranged between said pivotable roller table part and the beginning of the rear roller table.
1. Device for cutting rolled metal strip to length with a rotary shear, in which a gap between an end of a front roller table upstream of the shear and a beginning of a rear roller table downstream of the shear, where the rolled metal strip is unsupported, is reduced by a swiveling roller table part that supports the rolled metal strip as it passes through during a non-cutting operating phase of the shear, wherein a first movable guide table ( 18 ) is arranged between a swiveling roller table part ( 17 ) and the beginning of the rear roller table ( 4 ), wherein the swiveling roller table part is formed as a circle-segment that is rotatable about an axis so that an outer surface of the swiveling roller table part ( 17 ) is intermittently intermeshed with an outer surface of the first movable guide table ( 18 ) to intermittently close the gap as the roller table part ( 17 ) swivels, wherein the swiveling roller table part ( 17 ) is fastened to a rotational axis of a lower drum ( 8 ) independently of the lower drum.
2. Device in accordance with claim 1 , wherein a second movable guide table ( 19 ) is arranged between the end of the front roller table ( 3 ) and the swiveling roller table part ( 17 ).
3. Device in accordance with claim 1 , having an upper drum ( 6 ) and the lower drum ( 8 ) with flattened surfaces ( 15 , 15 ′, 16 , 16 ′) on their outer periphery.
4. Device in accordance with claim 3 , wherein a movable deflector ( 13 ) is arranged upstream of the upper drum ( 6 ).
5. Device in accordance with claim 3 , wherein a stationary or movable deflector ( 14 ) is arranged downstream of the upper drum ( 6 ).
