Definitions
- Rolling mill with means for changing rolls
- the invention relates to a rolling mill with a plurality of roll stands and with support plates provided on the operating side of the stands and displaceable transversely to the roll axes, which are equipped to accommodate work roll sets and which adjoin the hallway.
- the stands are preceded by pits on the operating side, the bottom of which is equipped for extending roller sets.
- Rolling mills are known with pits that are of displaceable, i.e. support plates which can be displaced in the rolling direction or against the rolling direction are overlapped.
- They are moved out of the roll stands by changing cylinders and placed on pairs of rails on the support plates.
- the roll changing cylinders can then move the new work roll sets into the stands.
- Tractors can take over the used sets of work rolls, if necessary after shifting the support plates again, and move them to the roll workshop.
- the support plates are lifted and stacked by means of cranes for the backup roller change, in which the backup roller sets are moved into the pits. This requires considerable time.
- DE 43 21 663 A1 proposes to provide the pits which are arranged between the rolling stands and the cross-displaceable support plate line with pivotable flaps. These flaps are in a horizontal position for changing the work roll, while they release the pit for retracting the support roll sets by a folding movement for changing the support roll.
- this known rolling mill with over Pits that can be closed by flaps between the scaffolding line and the support plate line, the work rolls must be moved over the flaps to the support plates. The transverse shifting and the exchange of the work rolls only take place on the support plates. The travel path is therefore relatively long and correspondingly time-consuming.
- the invention has for its object to provide a rolling mill in which both the work roll change and the backup roll change can be achieved within a short time sequence, in which the change can be made more efficient and thus the production time of the system can be increased can.
- the essence of the invention is that the support plates, which cover the pits directly next to the roll stands and take over the transverse displacement for the work roll change, also for the change of the support roll individually for a specific stand or completely for the entire rolling mill from the pit and thus the stand area, partially or completely are movable.
- the individual support plates are releasably connected to one another, so that either the entire support plate line or the support platform or only individual packages of support plates can be moved.
- individual stands of a multi-stand system can be equipped with new backup rolls more quickly.
- the used or new work rolls can remain on the support plates in the position to change the support rolls. This additional changeover time is therefore also eliminated with each backup roll change.
- the traversing area required for moving the support plate line is embedded in the hallway. It can also be covered with a cover which forms the hallway, so that the traversing area is available for other functions, for example as a parking area.
- a very advantageous bolt-wedge connection is proposed as a coupling of the individual plates, which can be opened and locked in particular with a special tool, which is described below.
- FIG. 1 shows a side view of a rolling mill with rolling stands and a support plate line arranged directly parallel to it with a travel area for the support plates in the fully extended state of the support plate line or support platform;
- Fig. 2 is a top view of the rolling mill of Fig. 1;
- Fig. 3 is a sectional view through the rolling mill; 4 shows the top view of the rolling mill according to FIG. 1 with the support plate line only partially extended;
- FIG. 5 shows the sectional view F-F of FIG. 1 to illustrate the arrangement of the rollers according to a first embodiment of the travel range
- Fig. 6 is a sectional view F-F showing the arrangement of the rollers according to a second embodiment of the travel range
- FIG. 7 shows a side view of a second embodiment of the rolling mill with a travel area for the support plate line below the hut floor in the extended state; 8 shows a side view of the rolling mill with a detailed representation of the substructure of the support plates;
- FIG. 9 shows the top view of the rolling mill according to FIG. 8.
- Fig. 10 is the sectional view F-F of Fig. 8;
- FIG. 11 shows the sectional view GG of FIG. 10 12 shows a cross section of a connection of two abutting support plates with a bolt-wedge connection with a wedge drawing tool;
- FIG. 13 is a sectional view of FIG. 12 with the wedge drawing tool not yet placed;
- FIG. 1 shows a side view of a rolling mill 1 with here six rolling stands (F1-F6) which are arranged firmly anchored on a foundation 2.
- the direction of rolling WR is marked with the arrow.
- a pair of scissors 3 and a scale washer 4 can be arranged in front of the rolling mill 1.
- a support plate line 6 composed of individual support plates 7 is arranged on the operating side (BS) of the rolling mill and immediately adjacent and parallel to the stand area 5, which is formed by the individual roll stands arranged one behind the other, as is illustrated in FIG. 2.
- the support platform, ie the entirety of all support plates 7, consists of one support plate 7 per roll stand F1-F6.
- These support plates 7 are arranged for work roll change above pits 8, which are located below the hut floor 9 (see FIG. 3).
- the run-out area 10 for the rolling stock extends, viewed in the rolling direction WR.
- a travel area 11 for the support plates 7 extends.
- This travel area 11, which is designed as a roller conveyor, is designed to be so long that all support plates 7 of the support plate line 6 in their entirety from the scaffolding area 5 can be moved parallel to the outlet area 10 and thus all pits 8 can be released for changing the support rollers 12.
- This extended state of the support platform is shown in FIGS. 1 and 2. The entire traversed support platform is identified by 6 ' .
- the work roll change or backup roll change with cross-slide support plates 7 and pits 8 will be explained with reference to FIG. 3.
- a roll stand Fi arranged on a foundation 2
- the extension movement is achieved by means of an extension cylinder unit 15.
- the respective pits 8 are covered with the support plates 7, which are provided with corresponding pairs of rails for extending and retracting the work roll sets 14, as an extension to the hut floor 9. Tractors (not shown) drag the used work rolls 14 ' onto the support plates 7 and, if necessary, back into the roll workshop.
- the transverse displacement of the support plates 7 for changing the work roll is accomplished by means of a hydraulic cylinder 16 (cf. FIG. 2). If a backup roll change is pending, the support plates 7 are moved out via the pits 8 transversely to the roll axes into the travel area 11. The pits 8 are then available for retracting the support roller sets 12 or for changing the support rollers.
- all support plates 7 in their entirety or only sub-groups 17 or sub-packages of support plates can be moved to open the pit 8 of a desired individual roll stand, which is shown in FIG. 4.
- the support plates arranged behind it in the rolling direction together with the support plate which is assigned to the fourth roll stand, are moved as a package 17 by the distance from a support plate in the direction of the rolling direction WR.
- the support roller set 12 of the fourth rolling stand F4 can then be moved into the now open pit 8 and replaced.
- the travel area 11 for the travel support plates 7 is arranged above the steel hall 18 behind the rolling mill stand.
- the hut hallway 18 in the outlet area is arranged in a lowered manner in relation to the hut hallway 9 in the scaffolding area - about 350 mm.
- Fig. 5 illustrates the arrangement of the support rollers 19 of the roller conveyor for conveying the support plates 7 in the travel area 11.
- the support rollers 19 are in lowered tracks 20 embedded in the foundation 2.
- a relatively flat surface 21 is created which can be run over by vehicles such as a truck or a mobile crane. Overall, the support platform is moved over these support roller tracks 20 or over the hut hallway 18.
- the support rollers can preferably be provided with a guide collar 22 on both sides.
- the travel area 11 can be run over by vehicles, but it must always be kept clear in order to enable the pits to be opened.
- the hut floor 23 in the travel area 11 is increased in relation to the hut hallway 9 in the scaffolding area, the support plates 7 running over the support rollers 19 below the hut floor 23 along the support roller tracks 24 then open between the rollers 19 (see Fig. 6). 7 shows that the support roller tracks 24 themselves are provided with a cover 25, so that the support plates 7 or the support platform can be moved under the cover 25. In this way it is achieved that the cover level and thus the hut floor 23 above the travel level can be used for other purposes.
- FIGS. 8 and 9 the substructure in the pit area 8 for the manufacture of roller conveyors is illustrated.
- three castors 26 are fastened to the foundation 2 via bearing blocks 27, the bearing blocks 27 being located between the individual roll stands Fi.
- a pinion gear 28 which is driven by an electric motor 30 via a gear 29 (see FIGS. 2, 10 and 11).
- the drive is composed, for example, of a direct current motor, a spur gear, an electromagnetic tooth clutch and a shaft that drive the rack and pinion gear 28.
- the drive rack pinion 28 engages in a drive gear toothing 31 on the underside 32 of the individual support plates 7. So that the support plates 7 do not tilt during the movement Side guide rollers 33, which roll along the side surfaces of the plates 7, are provided, which are also arranged on bearing blocks 34.
- the support plates 7 In order to enable a movement of the support plates 7 as a complete package or as a support platform or as a subpackage, they must be releasably connectable to one another.
- the abutting plate ends 35, 36 are coupled by means of a particularly advantageous bolt-wedge connection, as is illustrated in FIG. 12.
- flanges 37, 38 are welded to the undersides of the plates, each of which has a bore for receiving a common bolt 39.
- the bolt 39 which extends along the end regions 35, 36 of the plates, is guided through the flange 37 of the one plate and fastened with the aid of a holding plate 40 by means of screws 41, 42 and projects beyond the plate end 35.
- a wedge pulling tool 50 is provided, as is also illustrated in FIG. 13.
