Abstract
The invention relates to a rolling stand for rolled stock in sheet form, in particular for reversing rolling, with two work rolls (3), between which the rolled stock is passed, and with backup rolls (1) assigned to each of these work rolls, the backup rolls and the work rolls being respectively mounted in chocks and the backup rolls being assigned bending blocks (5). In this arrangement, the bending blocks (5) are connected to the backup roll chocks (2) and the work rolls (3) that are mounted in the chocks (4) are pivotable in an axially parallel manner about the backup roll axes together with the bending blocks (5) by adjusting means (6) articulated on the backup roll chocks (2).
Description
Technical field
The present invention relates to a kind of mill stand that is used for the orbit-shaped stocking, reversible is rolling especially for carrying out, have two stockings working roll that between them, moves and the backing roll that is equipped on each working roll, wherein no matter be that backing roll or working roll are bearing in the bearing block respectively, and set bending part (Biegebloecke) to backing roll.
Background technology
Mill stand by known a kind of this type of DE 33 27 433 C2.
When rolled strip, should note the different performance of band, different performances by producing different-thickness band or have strip material with different width, or process different quality of materials and reflect, these performances particularly tell on when employing has working roll than minor diameter, because working roll can be crooked to some extent.This bending must be offset by the corresponding preset of working roll.In DE 33 27 433 C2, set the supporting arrangement of band hydrostatic support element to working roll, so that supported towards the offset direction, supporting member be provided with static pressure, towards the pressure chamber for the treatment of area supported and be parallel to and respectively wait to support the setting of the working roll longitudinal axis, and do to such an extent that can control.Here backing roll is made with one and is adjusted roller by means of supporting member around the bending of the roller shell of a bracket supports.Working roll can be parallel to the stocking track cross level with the supporting arrangement that is equipped on it and move in mill stand.
The same working roll that is bearing in the bearing block by EP 0 233 597 B1 also can move horizontally, and wherein moves through guide rod device in this case and carries out, and this guide rod device guides by making eccentric rotary support, and is being adjustable aspect its motion.
Break away from this, known by EP 0 159 796 A1, the bending of the suitable or contrary stocking direction of motion of working roll is exerted one's influence.
Summary of the invention
The objective of the invention is, make can with simple device make the working roll axis from backing roll axis plane at a bigger scope bias internal, so that can offset different bendings thus.
For this reason, the present invention proposes a kind of mill stand that is used for the orbit-shaped stocking, it is rolling to be used to carry out reversible, described mill stand has two stockings working roll that moves and the backing roll that is equipped on each working roll between them, wherein no matter be that backing roll or working roll are bearing in the bearing block respectively, and set bending part to backing roll, it is characterized by: described bending part is connected with back-up chock, and be bearing in the bearing block working roll can by be hinged on adjusting device on the back-up chock and bending part together axis turn round around the backing roll axis abreast.
Wherein, adjusting device can adopt fluid pressure type, pneumatic type, mechanical type or electrodynamic type to drive.
Advantageously, adjusting device is equipped with the distance measurement sensor.
Description of drawings
With an embodiment the present invention is illustrated below, wherein schematically illustrates a reversible mill support in the drawings.
The specific embodiment
Backing roll 1 is bearing in the bearing block 2, and can be by hydraulic jack 6 around its axis revolution.Backing roll is adjusted by oil cylinder 14 and 15 with known method up and down.Top backing up roll oil cylinder 9 balances.Hydraulic cylinder 6 and 9 is fixed in the hydraulic cylinder piece 7, with the balance top backing up roll.Back-up chock 2 is fixed in slide block 10 and the friction plate 11.Slide block is vertically-guided in friction plate 12 and 13.
Working roll 3 itself is bearing in the bearing block 4, and its bottom bracket is connected with bending part 5, and bending part itself is fixed in the back-up chock 2, a hinged adjusting device 8 on back-up chock 2, and adjusting device is handled with hydraulic cylinder 6 in the present embodiment here.Can apply a substantially horizontal power by means of this hydraulic cylinder 6 on bending part 5, this power causes the revolution of bending part, thereby makes bearing block 4 revolutions of the working roll 3 that is connected with it.As seen in Fig., adjusting device on bending part, can turn round bending part from double side acting along the both direction axis abreast around the backing roll axis.Can when counter-rotating, offset the different bending of working roll in this way.
Claims (3)
1. the mill stand that is used for the orbit-shaped stocking, it is rolling to be used to carry out reversible, described mill stand has two stockings working roll that moves and the backing roll that is equipped on each working roll between them, wherein no matter be that backing roll or working roll are bearing in the bearing block respectively, and set bending part to backing roll, it is characterized by: described bending part (5) is connected with back-up chock (2), and be bearing in the bearing block (4) working roll (3) can by be hinged on adjusting device (6) on the back-up chock (2) and bending part (5) together axis turn round around the backing roll axis abreast.
2. by the mill stand of claim 1, it is characterized by: adjusting device (6) is that fluid pressure type, pneumatic type, mechanical type or electrodynamic type drive.
3. by the mill stand of claim 1 or 2, it is characterized by: adjusting device (6) sets the distance measurement sensor.
