Abstract

A shears device including a rolling table, a rail-guided drive carriage coupled with the rolling table, a U-shaped frame mounted on the drive carriage, and a drive apparatus arranged on the drive carriage for driving the shears. The frame has a first side adjacent the drive apparatus and a second side opposite the first side on which holding elements for the shears are provided. At least one of the holding elements on the second side of an upper of the horizontal arms includes a pressure plate. A drive is provided for moving the drive carriage transverse to the transport line. A clamping element is arranged at the second side of the frame and has congruent gliding plates that overlap the pressure plate. The clamping element together with the gliding plates is movable along a horizontal path across the pressure plate to couple the clamping element and the holding element.

Claims (38)

1. 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, the 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 at least one pressure plate;

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 arranged adjacent the second side of the arms, the clamping element having congruent gliding plates that overlap the at least one pressure plate; and wherein the clamping element together with the gliding plates is movable along a horizontal path across the at least one pressure plate so that the clamping element and the one of the holding elements are coupled.

2. 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.

3. The shears device according to claim 2 , wherein the contact between the rods and the sockets is form-fit/frictional contact.

4. 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, the 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;

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.
