A reversible two-high section roll stand 1 with multi-pass rolls 10, 11. The bearing blocks 14, 15 of these rolls 10, 11 are guided in windows 2c, 3c of the housings 2, 3 of the roll stand 1. The two-high section roll stand 1 is intended for a roll stand arrangement in which it is set up together with further roll stands of the same type side by side in rows, transversely to the rolling direction. In this arrangement, the rolls 10, 11 can be connected at their two ends with driving means or with drive transmission elements arranged between the rolls of adjacent roll stands. Supports 22, 23, 24, 25 connectable to the roll stand 1 are arranged for each of the rolls 10, 11 of the roll pairs on both sides of the roll gap formed by the latter, and assigned to and connectable to each of these supports 22, 23, 24, 25 are special adjustable and lockable guides 26, 27, 28, 29 for the rolling stock which are associated with the shaping grooves. The housings 2, 3 have connecting caps 4, 5 which are hinged on their posts 2a, 3a, can be pushed or pivoted upwards and, in the raised position, permit the removal of the rolls 10, 11. The bearing blocks 14, 15 of the roll pairs 10, 11 can be placed in a carrying frame 17, 18, 19. This carrying frame 17, 18, 19 can be pushed in and lifted out from between the posts 2a, 3a of the housings 2, 3. It is furthermore possible for the supports 22, 23, 24, 25 for the guides 26, 27, 28, 29 for the rolling stock to be inserted into this carrying frame 17, 18, 19. <IMAGE>

Description

Die Erfindung bezieht sich auf ein reversierbares Profil­walzgerüst mit Mehrkaliber-Walzen, deren Lagerstücke an­stellbar in Fenstern der Ständer des Walzgerüstes geführt sind, zur Anordnung zusammen mit weiteren, gleichartigen Walzgerüsten, nebeneinander in Reihen quer zur Walzrichtung, wobei die Walzen an beiden Stirnseiten mit den Antriebsein­richtungen bzw. zwischen den Walzen benachbarter Walzgerüste angeordneten Antriebs-Übertragungselementen verbindbar sind, und für jede der Walzen der Walzenpaare beiderseits des Walzspaltes besondere, den Profil-Kalibern zugeordnete ein­stell- und festlegbare Walzgut-Leitführungen jeweils gemein­sam auf mit dem Walzgerüst verbindbaren Trägern angeordnet sind.The invention relates to a reversible profile roll stand with multi-caliber rolls, the bearing pieces of which are adjustable in windows of the stands of the roll stand, for arrangement together with other, similar roll stands, side by side in rows transverse to the rolling direction, the rolls on both end faces with the drive devices or drive transmission elements arranged between the rolls of adjacent roll stands can be connected, and for each of the rolls of the roll pairs on both sides of the roll gap, special adjustable and definable rolling stock guide guides assigned to the profile calibers are each arranged together on supports which can be connected to the roll stand.

Reversierbare Duo-Profil-Walzgerüste dieser Ausbildung und Anordnung werden zum Walzen von verschiedenartigsten Profile in der Weise benutzt, daß das Walzgut in aufeinanderfolgen­den Stichen reversierend zunächst den Kalibern des einen Walzgerüstes und anschließend den Kalibern des benachbarten Walzgerüstes der Reihe zugeführt wird. Angetrieben werden die Walzgerüste einer Reihe dabei von einer mit den Walzen eines, den Beginn einer Reihe bildenden Walzgerüstes gekup­pelten Antriebseinrichtung, und die Übertragung der An­triebskraft erfolgt über die Walzen dieses Gerüstes auf die Walzen des nächsten Gerüstes der Reihe durch, die Walzen beider Gerüste miteinander kuppelnde Antriebs-Übertragungs­elemente. Die den einzelnen Walzen der Gerüste, also den Ober- und den Unterwalzen zugeordneten Walzgut-Leitführungen sind auf mit den Holmen der Walzenständer fest verbundenen Walzbalken angeordnet; sie müssen vor Beginn des Walzprozes­ses auf das ihnen zugeordnete Kaliber der jeweiligen Walze eingestellt werden und verbleiben in der Regel in dieser Einstellposition bis die Walzgerüste auf das Walzen anderer Profile umgestellt werden sollen. Diese Umstellung wird durch Auswechseln der Walzensätze aller Walzgerüste gegen andere bewirkt. Für das Auswechseln der Walzensätze müssen die Walzgut-Leitführungen aus ihrer Einstellposition heraus­gebracht werden, entweder indem man sie vollständig ausbaut oder aber auf dem Walzbalken verschwenkt oder verschiebt, um sie aus der Ausbau-Bewegungsbahn der Walzen herauszubringen. Der vollständige Ausbau der Walzgut-Leitführungen ist beson­ders dann nicht zu vermeiden, wenn für die Kaliber der neu einzusetzenden Walzen andere Ausbildungsformen der Leitfüh­rungen benötigt werden. Neben diesen Arbeiten ist es beim Wechsel der Walzen auch notwendig, die übrigen, für die Durchführung des Walzprozesses notwendigen Armaturen zu lösen, auszubauen oder zumindest aus der Ausbau-Bewegungs­bahn der Walzen herauszubringen, nämlich Vorrichtungen zur Kühlwasserzufuhr, zur Kaliberschmierung u.dgl. Nach Einbrin­gen der neuen Walzensätze ist es dann notwendig, die Walz­gut-Leitführungen wieder einzubauen bzw. wieder in ihre Betriebslage einzubringen, genau einzustellen und weiterhin auch die genannten Zusatzarmaturen wieder in Betriebsstel­lung zu bringen. Diese Arbeiten nehmen relativ viel Zeit in Anspruch und bedingen, da sie an den in Walzposition befind­lichen Walzgerüsten vorgenommen werden müssen, eine entspre­chend lange Unterbrechung des Walzbetriebes.Reversible duo-profile rolling stands of this design and arrangement are used for rolling a wide variety of profiles in such a way that the rolling stock in successive passes is first reversibly fed to the calibres of one rolling stand and then to the calibres of the adjacent rolling stand in the row. The rolling stands in a row are driven by one with the rollers one, the beginning of a row-forming roll stand coupled drive device, and the transmission of the drive force takes place via the rolls of this stand to the rolls of the next stand of the row by the drive transmission elements coupling the two stands together. The rolling stock guides assigned to the individual rolls of the stands, that is to say the upper and lower rolls, are arranged on rolling beams which are firmly connected to the spars of the roll stands; They must be set to the caliber of the respective roll assigned to them before the rolling process begins and generally remain in this setting position until the roll stands are to be converted to rolling other profiles. This change is made by replacing the roll sets of all roll stands with others. To replace the roller sets, the rolling stock guide rails must be brought out of their set position, either by completely removing them, or by pivoting or shifting them on the roller beam in order to bring them out of the removal path of the rollers. The complete expansion of the rolling stock guideways is particularly unavoidable if other types of guiding guideways are required for the calibres of the new rolls. In addition to this work, when changing the rollers, it is also necessary to loosen or remove the other fittings required for carrying out the rolling process, or at least to bring them out of the expansion path of the rollers, namely devices for supplying cooling water, for calibrating lubrication and the like. After introducing the new roller sets, it is then necessary to reinstall the rolling stock guideways or to bring them back into their operating position, to adjust them precisely and to bring the additional fittings mentioned back into operating position. This work takes a relatively long time Claim and condition, since they have to be carried out on the rolling stands in the rolling position, a correspondingly long interruption of the rolling operation.

Auch der Austausch der Walzensätze erfordert bei dieser Ausbildung und Anordnung von Duo-Profil-Walzgerüsten ver­hältnismäßig viel Zeit und auch Erfahrung, weil die Walzen­sätze mit ihren Lagerstücken nicht ohne weiteres aus den Ständern der Gerüste durch deren Fenster heraus- bzw. in diese eingefahren erden können. Die Gerüste einer Reihe stehen verhältnismäßig dicht nebeneinander und behindern den Ausbau der Walzensätze entsprechend. In der Regel müssen nach Lösen der Verbindungen mit der Antriebseinrichtung und den Antriebs-Übertragungselementen zunächst die Lagerstücke von den Enden der Walzen abgezogen und die Walzen schräg nach oben gekantet aus dem jeweiligen Fenster über das be­nachbarte Gerüst hinweg gezogen werden.The exchange of the roller sets also requires a relatively large amount of time and experience with this configuration and arrangement of duo-profile roll stands, because the roller sets with their bearing pieces cannot be easily moved out of or into the stands of the stands through their windows . The stands in a row are relatively close together and hinder the expansion of the roller sets accordingly. As a rule, after loosening the connections to the drive device and the drive transmission elements, the bearing pieces must first be pulled off the ends of the rollers and the rollers, bent obliquely upwards, must be pulled out of the respective window over the adjacent stand.

Der Erfindung liegt die Aufgabe zugrunde, die für die gat­tungsgemäße Anordnung bestimmten reversierbaren Duo-Profil-­Walzgerüste so zu verbessern, daß die Positionier- und Ein­stellarbeiten an den Walzgut-Leitführungen und den Zusatzar­maturen vereinfacht, die durch sie bedingten Stillstandszei­ten erheblich verringert und das Auswechseln der Walzensätze ebenfalls vereinfacht und die dazu benötigte Zeit verringert werden. Diese Aufgab wird dadurch gelöst, daß die Walzen­ständer bekannte, an ihre Holme angelenkte, für den Ausbau der Walzen nach oben ausschieb- bzw. ausschwenkbare Verbin­dungskappen aufweisen, und die Lagerstücke der Walzenpaare in ein Traggestell einlegbar sind, das zwischen die Holme der Ständer einschieb- und aus diesen heraushebbar ist, und in das die Träger der Walzgut-Leitführungen einsetzbar sind.The invention has for its object to improve the reversible duo-profile rolling stands intended for the generic arrangement in such a way that the positioning and adjustment work on the rolling stock guide guides and the additional fittings is simplified, the downtimes caused by them considerably reduced and the replacement of the Roller sets are also simplified and the time required for this can be reduced. This object is achieved in that the roller stands have known, hinged to their spars, which can be pushed out or swung out for the expansion of the rollers, and the bearing pieces of the roller pairs can be inserted into a support frame which is inserted between the spars of the stands. and can be lifted out of them, and into which the carriers of the rolling stock guide guides can be inserted.

Mit dieser Ausbildung wird die Möglichkeit geschaffen, die Walzenpaare mit ihren Lagerstücken, zusammen mit den Walz­gut-Leitführungen nach oben aus den Walzgerüsten herauszuhe­ben und gegen andere Walzensätze auszutauschen, wobei die Walzgut-Leitführungen in der für den Walzbetrieb eingestell­ten Position verbleiben. Die zeitaufwendige Einstellung der Walzgut-Leitführungen kann vorab außerhalb der Walzgerüste vorgenommen werden. Es ist lediglich notwendig, den komplet­ten Walzensatz mit fertig eingestellten Walzgut-Leitführun­gen von oben in das Walzgerüst einzusetzen und die Zusatz­armaturen anzukuppeln, um mit dem neuen Walzprozeß beginnen zu könnnen. Der Ein- und Ausbau der Walzensätze wird dabei durch die Walzen der benachbarten Gerüste nicht mehr behin­dert.With this design, the possibility is created to lift the roller pairs with their bearing pieces, together with the rolling stock guide guides, upwards out of the roll stands and to exchange them for other sets of rolls, the rolling stock guide guides remaining in the position set for the rolling operation. The time-consuming setting of the rolling stock guideways can be carried out in advance outside of the rolling stands. It is only necessary to insert the complete set of rolls with the rolling stock guide guides set into the roll stand from above and to couple the additional fittings in order to be able to start the new rolling process. The installation and removal of the roller sets is no longer hindered by the rollers of the neighboring stands.

Wie die Erfindung weiter vorsieht, kann das Traggestell aus einem, durch Abstandsglieder miteinander verbundenen, paral­lelflächigen, U-förmigen Plattenpaar bestehen, in dessen, in Einbauposition nach oben offene U-Ausnehmung die Lagerstücke der Walzen, im U-Flanschbereich geführt, einschiebbar sind, wobei die Stegbereiche der U-Ausnehmung Auflageflächen für die Unterseite der Lagerstücke der unteren Walzen bilden, und das einander gegenüberliegende Schlitz-Ausnehmungen zum Einsatz und Verschieben der Träger der Walzgut-Leitführungen aufweist. Die U-Ausnehmung kann im Öffnungsbereich einander gegenüberliegende, in die Öffnung ragende, von den oberen Eckkanten der Lagerstücke der oberen Walze unterfaßbare Ansätze aufweisen, die es erlauben, beim Anheben der oberen Walze das von dem Plattenpaar gebildete Traggestell mit der Walze anzuheben.As the invention further provides, the support frame can consist of a parallel-sided, U-shaped plate pair connected by spacers, into whose, in the installation position open upward U-recess, the bearing pieces of the rollers, guided in the U-flange area, can be inserted, wherein the web areas of the U-recess form support surfaces for the underside of the bearing pieces of the lower rollers, and which has opposing slot recesses for inserting and displacing the carriers of the rolling stock guide rails. The U-recess can have, in the opening area, mutually opposite, projecting into the opening, graspable from the upper corner edges of the bearing pieces of the upper roller, which make it possible to lift the supporting frame formed by the pair of plates with the roller when lifting the upper roller.

Das Walzgerüst 1 wird aus den Ständern 2 und 3 mit den Hol­men 2a, 3a und den Verbindungskappen 4 und 5 gebildet. Die Verbindungskappen 4 und 5 sind durch eine Quertraverse 6 starr miteinander verbunden. In den Verbindungskappen 5 sind die Anstellspindeln 7 in Spindelmuttern 8 gewindegeführt; sie werden gemeinsam über auf den Verbindungskappen 5 ange­ordnete Anstellgetriebe 8a, die über eine Verbindungswelle 9 miteinander gekuppelt sind, angetrieben. Die obere und die untere Walze des Duo-Walzensatzes weisen hier sechs Kaliber­rinnen auf, die zusammen (vgl. Fig. 1 ) die dort schaffiert angedeuteten Walzkaliber bilden. Die Lagerstücke 14 der oberen Walze 10 und die Lagerstücke 15 der unteren Walze 11 sind (Fig. 2) in den von den Holmen 2a, 3a gebildeten Fen­ stern 2c bzw. 3c geführt. Die Lagerstücke 14 hängen mit Hakenansätzen 14a an einer Hubtraverse 16, die eine Kranöse 16a aufweist. Die Hubtraverse 16 hängt ihrerseits an Hubzy­lindern 37, die mit der Quertraverse 6 verbunden sind und wird von der Anstellspindel 7 beaufschlagt. Die untere Walze 11 wird mit ihren Lagerstücken 15 ebenfalls in den Fenstern 2c bzw. 3c der Ständer 2 und 3 geführt.The roll stand 1 is formed from the stands 2 and 3 with the spars 2a, 3a and the connecting caps 4 and 5. The connecting caps 4 and 5 are rigidly connected to one another by a crossbar 6. In the connecting caps 5, the adjusting spindles 7 are threaded in spindle nuts 8; they are driven together via adjusting gear 8a arranged on the connecting caps 5 and which are coupled to one another via a connecting shaft 9. The upper and lower rollers of the duo roller set here have six caliber channels, which together (see FIG. 1) form the roller calibers indicated there. The bearing pieces 14 of the upper roller 10 and the bearing pieces 15 of the lower roller 11 are (FIG. 2) in the fen formed by the spars 2a, 3a star 2c or 3c led. The bearing pieces 14 hang with hook attachments 14a on a lifting traverse 16, which has a crane eye 16a. The lifting crossbar 16 in turn hangs on lifting cylinders 37 which are connected to the crossbar 6 and is acted upon by the adjusting spindle 7. The lower roller 11 is also guided with its bearing pieces 15 in the windows 2c and 3c of the stands 2 and 3.

Wie weiter aus Fig. 1 und 2 in Verbindung mit Fig. 3 zu ersehen, ist zwischen die beiden Ständer 2 und 3 ein aus parallelflächigen Platten 17 und 18 und Abstandsstäben ge­bildetes Traggestell geschoben. Die parallelflächigen Plat­ten 17 und 18 weisen eine U-Ausnehmung 20 auf, in deren Flanschbereichen die Lagerstücke 14 und 15 beider Walzen 10 und 11 einschiebbart geführt sind. Die Lagerstücke 15 der unteren Walze 11 liegen dabei mit ihrer Unterseite auf den nach oben gerichteten Flächen des Stegbereiches der U-Aus­nehmung 20 auf. Ferner weisen beide parallelflächigen Plat­ten 17 und 18, im Einbauzustand einander gegenüberliegende Schlitzausnehmungen 21 auf, in denen verschieb- und festleg­bar die den Ein- und Ausgangsseiten der Walzspalte und den jeweiligen Walzen vorgeordneten Walzbalken 22, 23 bzw. 24, 25 geführt und festlegbar sind. Auf diesen einzelnen Walz­balken sind hier, jeweils sechs Walzgut-Leitführungen 26 bzw. 27 bzw. 28 bzw. 29 einstell- und festlegbar angeordnet.As can be seen further from FIGS. 1 and 2 in connection with FIG. 3, a support frame formed from parallel plates 17 and 18 and spacer bars is pushed between the two stands 2 and 3. The parallel-surface plates 17 and 18 have a U-recess 20, in the flange areas of which the bearing pieces 14 and 15 of both rollers 10 and 11 are guided in a push-in manner. The bearing pieces 15 of the lower roller 11 lie with their underside on the upward-facing surfaces of the web area of the U-recess 20. Furthermore, both parallel-surface plates 17 and 18, in the installed state, have mutually opposite slot recesses 21, in which the rolling beams 22, 23 and 24, 25 arranged upstream of the entry and exit sides of the roll nips and the respective rolls can be moved and fixed. On each of these individual rolling beams, six rolling guide guides 26, 27, 28, and 29, respectively, are arranged to be adjustable and fixed.

Wie aus den Fig. 3, 4 und 5 zu ersehen, sind im Stegbereich der U-Ausnehmungen 20 der parallelflächigen Platten 17, 18 nach außen gerichtete Kragansätze 30 angesetzt. Diese Krag­ansätze 30 sind mit ihren nach unten weisenden Flächen auf die untere Begrenzung der Fenster 2c, 3c der Walzenständer 2, 3 auflegbar (vgl. Fig. 2). Der aus der oberen Walze 10, der unteren Walze 11, den Lagerstücken 14 und 15, den Walz­balken 22, 23, 24, 25 und den auf diese montierten und ein­ stellpositionierten Walzgut-Leitungstührungs-Sätzen 26, 27, 28, 29 bestehende, betriebsfertige Walz-Satz wird, wie insb. Fig. 3, 4 und 5 zeigen, von dem parallelflächigen Platten­paar 17, 18 in Verbindung mit der Hubtraverse 16 gehalten und getragen. Er kann aus der in den Fig. 1 und 2 wiederge­gebenen Walzposition zwischen den Ständern 2a, 3a des Walz­gerüstes 1 bspw. mit Hilfe eines krans, nach oben aus dem Walzgerüst 1 herausgehoben werden. Zu diesem Zweck werden die Verbindungskappen 4, 5, die mit Scharniergelenken 31 (Fig. 1 und 2) an die freien Enden der nebeneinander aufste­henden Holme 2a bzw. 3a der Ständer 2, 3 des Walzgerüstes 1 angelenkt sind, nach seitlichem Herausziehen der Gelenkbol­zen 32 auf nicht dargestellte Weise abgehoben. Es besteht auch die Möglichkeit, die Verbindungskappen 4, 5 stattdes­sen, wenn die baulichen Verhältnisse dies erlauben, um je­weils einen der Gelenkbolzen 32 nach außen zu verschwenken und so den Aushebeweg für den erwähnten Walzsatz freizuma­chen. Beim Anheben der Hubtraverse 16 (Fig. 5) wird das obere Lagerstück 14, das hierzu seitliche Kragansätze 33 aufweist, von im Öffnungsbereich der U-Ausnehmung 20, einan­der gegenüberliegend in die Öffnung ragenden Ansätzen 17a bzw. 18a gehalten, nachdem es von Lagerstück 15 wegbewegt wurde. Die Kragansätze 33, an deren Stelle bspw. auch die oberen Eckkanten der Lagerstücke treten könne, unterfassen dabei die Ansätze 17a und 18a.As can be seen from FIGS. 3, 4 and 5, outwardly directed cantilever projections 30 are attached in the web area of the U-recesses 20 of the parallel-surface plates 17, 18. These cantilever projections 30, with their surfaces pointing downward, can be placed on the lower boundary of the windows 2c, 3c of the roller stands 2, 3 (cf. FIG. 2). The one from the upper roller 10, the lower roller 11, the bearing pieces 14 and 15, the roller beams 22, 23, 24, 25 and the one mounted on them 3, 4 and 5, the parallel set of plates 17, 18 hold and carry in connection with the lifting cross member 16 and the positionally positioned rolling stock line guide sets 26, 27, 28, 29. It can be lifted upwards out of the roll stand 1 from the rolling position shown in FIGS. 1 and 2 between the stands 2a, 3a of the roll stand 1, for example with the aid of a crane. For this purpose, the connecting caps 4, 5, which are articulated with hinge joints 31 (FIGS. 1 and 2) to the free ends of the uprights 2 a and 3 a of the stands 2, 3 of the roll stand 1, after the articulated bolts 32 have been pulled out sideways lifted off in a manner not shown. It is also possible, if the structural conditions permit, to connect the connecting caps 4, 5 instead, in order to pivot one of the hinge pins 32 outwards and thus free the lifting movement for the roll set mentioned. When lifting the lifting traverse 16 (FIG. 5), the upper bearing piece 14, which for this purpose has lateral cantilever projections 33, is held by projections 17a or 18a, which project into the opening opposite one another in the opening area of the U-recess 20, after it has been removed from bearing piece 15 was moved away. The cantilever lugs 33, in the place of which, for example, the upper corner edges of the bearing pieces can also occur, underlie the lugs 17a and 18a.

Nach Ausheben des Walzsatzes kann dieser durch einen außer­halb des Walzgerüstes 1 vorbereiteten entsprechend walzfer­tig gemachten Walzensatz ersetzt werden, und der Walzprozeß kann nach Wiedereinbringen der Verbindungskappen 4, 5 sofort fortgesetzt werden. Die zeitliche Unterbrechung beschränkt sich auf das Ausheben und Wiedereinsetzen der jeweils außer­halb der Walzgerüste komplett vorbereiteten Walzsätze.After the roll set has been lifted out, it can be replaced by a roll set prepared outside of the roll stand 1 and made ready for rolling, and the rolling process can be continued immediately after the connection caps 4, 5 have been reinstalled. The interruption in time is limited to the lifting and reinserting of the roll sets that are completely prepared outside the roll stands.
