Definitions
- the invention relates to a device for bending the rolls in a multi-roll mill stand with bending blocks which can be acted upon by actuating means and are fastened on the inlet and outlet sides between the roll chocks and the stator windows.
- Generic devices are used for flatness control of a rolled product as an actuator for work roll bending.
- the actuator has a direct influence on the roll gap geometry in the strip edge area, the work rolls being bent positively around the edges of the rolls above and negatively bent around the edges of the rolling stock.
- German patent specification 22 50 953 is a roll stand with work and support rolls and a roll bending device, in which the chocks of the work rolls are guided between blocks anchored in the stand windows and to act upon the work roll bale correction by piston cylinders which can be loaded on both sides and assigned to the blocks -Units connected are known, with a lower and an upper guide piece being guided vertically displaceably on each block, whereas one guide piece receives the cylinder and the other guide piece is connected to the piston, and the guide pieces with the chocks by horizontal guides in the vertical direction in a form-fitting manner are connected, which are continued parallel to the rolls for the roll change between the stands. In this way it should be achieved that two piston-cylinder units are required on each side for the roll bending.
- the object of the invention is to reduce the frictional forces in a generic system.
- the bending blocks of the one roll stand be assigned a piston cylinder and the bending blocks of the opposite roll stand a vertical positioning device.
- a pivot point can be created around which the chock can be pivoted. Only one cylinder is required to introduce the bending force on the drive and operator side into the bending blocks.
- the grinding range of the rollers can also be compensated for by the screw jack.
- the device according to the invention can also be used for intermediate roll bending in a six-roll stand. Use in reversing roll stands is also conceivable.
- Figure 1 is a side view section of a four-high rolling mill from the
- FIG. 2 is a plan view of the work roll level of the roll stand from FIG. 1.
- a roll stand 1 the work rolls 3, 3a are supported by the support rolls 2, 2a.
- the chocks 4, 4a of the work rolls are connected to the roll stand 6, 6 'via the bending blocks 5, 5a, 5', 5a '.
- a screw jack 10 is arranged between the bending blocks 5 'and 5a' and can be positioned and locked via a drive 12.
- the bending blocks 5 and 5a are connected via a piston cylinder 7, the piston 9 of which is mounted in the bending block 5a, while its connecting rod 8 is mounted in the bending block 5.
- the bending blocks 5, 5a, 5 'and 5a' can be connected to the chocks 4, 4a of the work rolls 3, 3a on the one hand and the roll stand 6, 6 'on the other hand in a known manner.
- the direction of rolling of the rolling stock is shown by the double arrow 11.
- the bending blocks 5 ', 5a' are positioned and locked with the screw jack, while the piston cylinder 7, which connects the bending blocks 5 and 5a, introduces the necessary bending force.
- the invention is not limited to the use of screw jacks, but any mechanism for vertical positioning can be used, for example wedges with positive guidance, cylinders with clamping heads and position sensors or an eccentric shaft.
