Abstract

The invention relates to a device 1 for positioning an edging roll 10 of an edging stand, comprising an edging frame 12 to which at least one balancing cylinder 14 is attached, a balancing crossbeam 16 with a drive side 18 positioned opposite of the edging frame 12, and a working side 19 positioned opposite of the drive side 18, wherein a bearing device 20 for the edging roll 10 can be attached, in particular in an interlocking manner, to the balancing crossbeam 16 on the working side 19 thereof and at least one linkage 24 is provided on the drive side 18 thereof, by which linkage the balancing cylinder 14 is in an operative connection with the balancing crossbeam 16, and at least one positioning cylinder 26 attached to the edging frame 12 can be brought into an operative connection with the bearing device (20) in the direction of a rolled material in order to position the edging roll 10 against the rolled material, wherein the compressive force generated by the positioning cylinder 26 acts on the bearing device 20 along an operational axis 28, which either intersects with the at least one linkage 24 by which the balancing cylinder 14 is operatively connected with the balancing crossbeam 16 or runs directly alongside this linkage 24.

First claim

The invention claimed is:

1. A device for positioning an edging roll ( 10 ) of an edging stand, comprising:
an edging stand, to which at least one balancing cylinder is attached;
a balancing crossbeam with a drive side positioned opposite the edging stand and a working side positioned opposite the drive side, wherein a bearing device for the edging roll is selectively attached to the working side of the balancing crossbeam, and at least one linkage is provided on the drive side of said balancing crossbeam, by which the at least one balancing cylinder is in an operative connection with the balancing crossbeam, and
a positioning cylinder arranged on the edging stand, which can be brought into an operative connection with the bearing device in a direction of a rolled material in order to position the edging roll against the rolled material, wherein a compressive force generated by the positioning cylinder acts on the bearing device along an operational axis, which either intersects with the at least one linkage by which the at least one balancing cylinder is operatively connected with the balancing crossbeam, or a line of action of the compressive force is directed to the working side adjacent to the at least one linkage so that no tilting moment is applied to the bearing device and the edging roll supported therein;
wherein the at least one balancing cylinder includes two balancing cylinders with the positioning cylinder arranged therebetween on the edging stand; wherein an actuator of each of the balancing cylinders is articulated on the drive side of the balancing crossbeam; wherein between the edging stand and the balancing crossbeam, a supplementary component is arranged so that an actuator of the positioning cylinder is selectively brought into an operative connection with the supplementary component; wherein the supplementary component is positioned opposite of the drive side of the balancing crossbeam and includes two elongated pressure pins, whose longitudinal axes defines an operational axis, and which are selectively extendable across the balancing crossbeam, wherein upon extension and translation of the actuator of the positioning cylinder, the compressive force of the positioning cylinder is branched out to the two pressure pins and is transmitted onto the bearing device for the edging roll on the working side of the balancing crossbeam.

2. The device according to claim 1 , wherein a point of contact between at least one of the actuator of the positioning cylinder and the supplementary component has a convex shape.

3. The device according to claim 2 , wherein the point of contact is embodied as a point contact or as a surface contact.

4. The device according to claim 2 , wherein the point of contact is defined by respective convex surfaces or by one convex surface and one concave surface.

5. The device according to claim 1 , wherein the actuator of the positioning cylinder is connected with the supplementary component by a cylinder head, such that transverse forces operating on the pressure pins and/or on the supplementary component in the direction transverse to the operational axis are transmitted to the positioning cylinder.

6. The device according to claim 1 , wherein the actuator of the positioning cylinder is connected with the supplementary component by an articulate joint.

7. The device according to claim 1 , wherein the bearing device for the edging roll consists of an upper edging roll chock and a lower edging roll chock, such that the edging roll is incorporated on bearings between the edging roll chocks.

8. The device according to claim 1 , wherein the pressure pins extend through the balancing crossbeam and are longitudinally guided in slide bearings within the balancing crossbeam.

9. The device according to claim 1 , wherein a contact surface is formed on the bearing device for the edging roll, by which the front face of each pressure pin is brought into a contact position in case of an actuation of the positioning cylinder.

10. The device according to claim 9 , wherein the point of contact between at least one of the front face of each pressure pin and a corresponding contact surface of the bearing device has a convex shape, such that a point contact is formed on the point of contact.

11. The device according to claim 1 , wherein a movement path of the balancing cylinders in the direction of the rolled material is longer than a movement path of the positioning cylinder, such that the edging roll can only be moved into the middle of a rolling line on which the device is positioned through the actuation of the balancing cylinders.

12. The device according to claim 1 , wherein the positioning cylinder is operated in one direction towards the rolled material.

13. The device according to claim 1 wherein the balancing cylinders are operated bi-directionally, such that the balancing crossbeam and therefore the bearing device for the edging roll can be moved back and forth by the balancing cylinders.

14. The device according to claim 1 , wherein at least one position sensor is provided, such that the at least one position sensor is in a signal connection with an evaluation device, such that a current position of the edging roll can be determined.

15. The device according to claim 14 , wherein the evaluation device is in a signal connection with a control device for the balancing cylinders and for the positioning cylinder, such that the balancing cylinders and/or the positioning cylinder can be controlled as a function of a measurement signal from the at least one position sensor ( 44 , 46 ), and the control of the balancing cylinders and/or of the positioning cylinder can be regulated.
