Device for cutting a work piece in a transport line

A shears device, comprising:

• a rolling table having a movable part;
• a rail-guided drive carriage coupled with the movable part of the rolling table;
• a U-shaped frame incorporating a vertical base and two horizontal arms that make the frame U-shaped, the arms having first and second sides, the first sides of the arms being connected to the vertical base, the U-shaped frame being mounted on the drive carriage;
• a transport line extending through the horizontal arms;
• shears;
• a drive apparatus arranged on the drive carriage for driving the shears;
• the shears arranged on the U-shaped frame, first side of the arms being adjacent the drive apparatus and the second side of the arms being opposite the first side;
• holding elements provided on the first side and the second side of the arms;
• blade holders supported by the holding elements, the shears being supported by the blade holders, wherein one of the holding elements on the second side of an upper of the horizontal arms has threaded spindle coupling rods connected so as to be pivotable to both the first side and the second side of the arms, the coupling rods are pivotable through recesses in the drive carriage so as to engage in congruent coupling sockets of a lower of the horizontal arms or in congruent coupling sockets of the one of the holding elements on the upper of the arms;
• a drive for moving the drive carriage transverse to the transport line while a work piece is positioned in the transport line;
• and
• a means for pivoting the coupling rods into contact with one of said coupling sockets.

• a drive for moving the drive carriage transverse to the transport line while a work piece is positioned in the transport line;
• a clamping element correlated transversely to the two horizontal frame arms, the clamping element is configured to pivot about a pivot joint, wherein the pivot axis of the pivot joint extends parallel to the transport line;
• and
• a means for pivoting the clamping element between a position wherein the clamping element couples the two horizontal arms and a position wherein the coupling element does not couple the two horizontal arms.
