Definitions
- the invention relates to a device for locking the chock and the thrust bearing housing of a set of rollers and the roll change carriage when rolling and when changing rolls.
- the wear on the rolls of a roll stand or a program change requires a change of the roll sets in the individual rolling stands of a rolling mill.
- a roll changing car is used in practice, with the roll sets in the rolling stand einfahr- or out of this are mobile.
- the roll change carriage is locked in position on the roll stand with specially provided locking tabs. It is also known that the locking tabs attached to the operating side for locking the chocks in the framework are combined with the axial displacement of the work rolls (4 roll rolling stand) or intermediate rolls (18 HS rolling mill stand).
- the axial bearing is not firmly connected to the chock during roll change. This has the consequence that during the retraction / extension of the rollers in / out of the framework by means of roll changing trolley, which pushes or pulls the set of rollers on the thrust bearing, the position of the chocks relative to the thrust bearing changed, causing difficulties in locking in Rolling mill leads or the position of the set of rollers on the carriage does not correspond to the desired.
- the object of the invention is to avoid the disadvantages described above.
- a device for locking the chock and the Axiallagergeophuses a set of rollers and the Walzen cafeteils when rolling and when changing rolls characterized in that on the roll stand a vertically and horizontally displaceable locking device is provided which has locking elements on the the locking device for axial displacement of the roller with the roll chock, for fixing the position of the thrust bearing housing with respect to the chock of the roller or the roll changing carriage in the roll change position can be locked.
- the new locking concept combines the two functions in such a way that the combined axial displacement locking in addition to the locking of the work roll chocks in the 4-roll rolling stand or the locking of the intermediate roll chocks in the 18 HS rolling stand and the axial displacement of the rolls in the chocks, in addition also the locking of the Roller changing carriage in the change position on the rolling mill allows without a separate function would be required.
- the new concept also provides for the case of roll change a locking of the thrust bearing, by means of a pivoting bolt, with the chock before. This ensures that during the roll change, the set of rolls does not change in itself and proper locking in the framework or a correct positioning on the roll changing car is possible.
- Fig.1 illustration of the lock on the chock / Axiallagerge- housing
- Fig. 1 the situation can be seen, in which the roller is in the rolling stand in use.
- the guided on the roll stand combined lock / axial displacement 2 locks the chock 3 of the set of rollers with the locking element 4 and the thrust bearing 5 of the set of rollers with the locking element. 6
- FIG. 2 shows the situation in which a roll change is taking place. Both the chock 3 and the thrust bearing 5 are unlocked.
- the new concept includes a device for locking the chock 3 to the thrust bearing housing 5 by means of a pivotable bolt 8, which is provided with a locking element 9 which on the Block of combined locking / axial displacement 2 is attached, can be opened and the drive when driving the locking element 9, by its own weight, the chock 3 with the thrust bearing 5 via an axially mounted bolt 10 which is fixedly mounted on the chock 3 and by the Axiallager- housing 5 is guided axially locked.
- the bolt 10 is beveled at the end, so that in the collapse of the set of rollers, the pivotable latch 8 can push away on the slope, and then falls upon complete collapse of the set of rollers by its own weight in the groove 10 provided in the bolt.
- two stops 11 are attached to the thrust bearing housing 5.
