Abstract
Description
Die Erfindung betrifft eine Walzgerüstanordnung für das Walzen von Draht oder Feineisen, bestehend aus einer Mehrzahl von in Walzrichtung hintereinander angeordneten, anstellbare Walzenpaare aufweisenden Walzgerüsten, von denen jedes lösbar mit einem Traggehäuse verbindbar ist, in dem parallel zur Walzrichtung eine motorantreibbare Kegelradwelle lagert, deren Kegelrad mit einer Kegelradwelle kuppelbar ist, die mit den Tragwellen des Walzenpaares des Walzgerüstes antriebsverbindbar ist. Bei bekannten Walzgerüsten dieser Art (OS 4 537 055) sind die aufeinanderfolgenden Walzgerüste gemeinsam auf einer Tragplattform so angeordnet, daß die Achsen der Walzenpaare benachbarter Walzgerüste um 90° gegeneinander winkelversetzt sind, wobei die antriebsverbindbaren Kegelradwellen parallel zur Achsrichtung der jeweiligen Walzenpaare verlaufen mit der Folge, für die parallel zu der einen Achsrichtung verlaufenden und die parallel zu der anderen Achsrichtung verlaufenden Kegelradwellen je eine eigene motorantreibbare Kegelradwelle erforderlich ist. Diese beiden, parallel zur Walzrichtung verlaufenden Kegelradwellen bestehen meist aus zwischen den Traggehäusen der Walzgerüste miteinander gekuppelten Wellenabschnitten und werden entweder von je einem eigenen Motor oder über ein Getriebe gemeinsam von einem Motor angetrieben (EP 543 479).The invention relates to a roll stand arrangement for rolling wire or Fine iron, consisting of a plurality of one behind the other in the rolling direction, adjustable roll stands, of which each is releasably connectable to a support housing in which parallel to the rolling direction a motor-driven bevel gear shaft, the bevel gear with a bevel gear shaft can be coupled with the support shafts of the pair of rollers of the roll stand is drive-connectable. In known rolling stands of this type (OS 4 537 055), the successive rolling stands are together on a support platform so arranged that the axes of the pairs of rolls of adjacent roll stands are angularly offset from one another by 90 °, the drive-connectable bevel gear shafts run parallel to the axial direction of the respective roller pairs with the Sequence for those running parallel to one axis direction and those parallel to the other axis direction running bevel gear shafts each have their own motor-driven Bevel gear shaft is required. These two, parallel to the rolling direction extending bevel gear shafts usually consist of between the support housings of the mill stands are coupled together and either each with its own engine or together via one gearbox Motor driven (EP 543 479).
Es wurde auch schon vorgeschlagen, die Walzenpaare einzelner Walzgerüste oder die von Blöcken zweier Walzgerüste statt über Kegelradwellen direkt mit neben den Walzgerüsten angeordneten, einem oder mehreren Gerüsten zugeordneten Übertragungsgetrieben zu kuppeln (EP 694 345 und 695 589). It has also been suggested that the roller pairs of individual roll stands or that of blocks of two rolling stands instead of right next to bevel gear shafts arranged to the rolling stands, assigned to one or more stands To couple transmission gears (EP 694 345 and 695 589).
Alle diese Bauformen von Walzgerüstanordnungen gattungsgemäßer Art erfordern nicht nur einen mehr oder weniger großen Herstellungsaufwand für die doppelten Antriebswellen oder die großen Getriebe; sie erfordern darüber hinaus auch einen großen Wartungsaufwand.All of these types of roll stand arrangements of the generic type require not just a more or less large production effort for the double Drive shafts or the big gears; they also require one great maintenance.
Der Erfindung liegt die Aufgabe zugrunde, den Antrieb dieser Walzgerüstanordnungen so zu verbessern, daß neben einem erheblich geringeren Herstellungsaufwand auch der Wartungsaufwand herabgesetzt wird.The invention has for its object the drive of these roll stand arrangements to improve so that in addition to a significantly lower manufacturing cost maintenance work is also reduced.
Diese Aufgabe wird dadurch gelöst, daß bei bekannter Anordnung benachbarter Walzgerüste, mit gegeneinander winkelversetzten Achsrichtungen ihrer Walzenpaare das Kegelrad der mit den Tragwellen der Walzenpaare antriebsverbindbaren Kegelradwellen des jeweiligen Walzgerüstes mit einem diesem zugeordneten Kegelrad kuppelbar ist, das zusammen mit den benachbarten Walzgerüsten zugeordneten Kegelrädern auf einer diesen gemeinsamen motorantreibbaren Kegelradwelle sitzt. Bei einer Winkelversetzung der Achsrichtungen um 90° können dabei, wie die Erfindung weiter vorsieht, die mit den Tragwellen des Walzenpaares verbindbaren Kegelradwellen quer zu deren Achsrichtung im Traggehäuse gelagert sein. Auf der quer gelagerten Tragwelle kann dabei ein walzenförmiges Stimrad sitzen, das mit einem Paar von auf den freien Enden der Tragwellen des Walzenpaares sitzenden Kronenrädern kämmt. Die Tragwellen des Walzenpaares können dabei, wie die Erfindung weiter vorsieht, in, in den Walzgerüsten gleitverschiebbar angeordneten Lagereinbaustücken lagern, die über in ihnen gewindegeführten und von Schnecken getrieben angetriebenen Spindeln gegeneinander anstellbar sind. Ein weiterer Vorschlag der Erfindung geht dahin, jeweils zwei benachbarte, in diese ein- und ausfahrbare Walzgerüste und die gemeinsame motorantreibbare Kegelradwelle aufnehmendes Traggehäuse vorzusehen.This object is achieved in that neighboring arrangements are known Roll stands, with axially offset axial directions of their roller pairs the bevel gear of the drive connectable with the support shafts of the roller pairs Bevel gear shafts of the respective roll stand with an associated one Bevel gear can be coupled, which is assigned together with the adjacent roll stands Bevel gears on a common motor-driven bevel gear shaft sits. If the axial directions are offset by 90 °, as the invention further provides that with the support shafts of the pair of rollers connectable bevel gear shafts mounted transversely to their axial direction in the support housing his. A roller-shaped spur wheel can be placed on the transversely mounted support shaft sit that with a pair of on the free ends of the support shafts of the pair of rollers combed crown gears. The support shafts of the pair of rollers can, as the invention further provides, slidably in, in the rolling stands store the arranged bearing chocks, which are threaded in them and spindles driven by worms against each other are employable. Another proposal of the invention is to use two neighboring into these retractable and extendable mill stands and the common motor-driven To provide bevel gear shaft supporting housing.
Neben den bereits erwähnten Vorteilen ermöglicht die Lagerung der Walzenpaare in anstellverschiebbaren Lagereinbaustücken eine geradlinige und symmetrische Einstellung des Walzspaltes für Walzenpaare, die bisher über die Lager der Walzen aufnehmende Exzenterbüchsen erfolgte. Die Antriebsübertragung über die mit dem walzenförmigen Stirnrad kämmenden Kronenrädern erlaubt dabei, diese mit axialer Freiheit über die Länge der Verzahnung des Stirnrades zu verschieben, dabei werden die Walzkräfte, ähnlich wie bei ständerlosen Walzgerüsten, von den Spindeln aufgenommen, so daß sich das Walzgerüst entsprechend leicht bauen läßt. Auch das, jeweils zwei Walzgerüste aufnehmende Traggehäuse kann sehr leicht gebaut werden, weil die beiden auf der Antriebskegelradwelle sitzenden Kegelräder wegen ihrer Anordnung Rücken gegen Rücken einen weitgehenden Ausgleich der auftretenden Axialkräfte herbeiführen. Die erfindungsgemäße Ausbildung der Antriebsübertragung mit Stirnrad und Kronrad ist auch bei Cantilever-Gerüsten mit Einzelantrieb und bei zweigerüstigen Vorblöcken anwendbar und bringt die schon erwähnten Vorteile mit sich. Die Antriebsübertragung eignet sich sowohl für Tragwellen mit fliegend angeordneten Walzen als auch für zweiseitig gelagerte Walzen, und sie ist besonders für Übersetzungen ins Langsame geeignet.In addition to the advantages already mentioned, the roller pairs can be supported in adjustable bearing chocks a straight and symmetrical Adjustment of the roll gap for pairs of rolls, which previously used the bearings of the rolls receiving eccentric bushes. The drive transmission via the the cylindrical spur gear meshing crown gears allows this with axial freedom to move over the length of the toothing of the spur gear, the rolling forces are similar to that of column-free roll stands Spindles added so that the roll stand can be built accordingly easily leaves. The support housing, which accommodates two roll stands, can also be very powerful be built easily because the two bevel gears sitting on the drive bevel gear shaft because of their back-to-back arrangement, they are largely balanced bring about the occurring axial forces. The training according to the invention the drive transmission with spur gear and crown gear is also available with cantilever stands can be used with single drive and with two-stand blooms and brings the advantages already mentioned. The drive transmission is suitable for support shafts with overhung rollers as well as for two-sided stored rollers, and it is particularly suitable for slow translations.

Wie aus Fig. 1 zu ersehen, sind in das Traggehäuse TG zwei Walzgerüste WGI und WGII eingeschoben. In dem Traggehäuse TG lagert eine Kegelradwelle KW, auf der beabstandet voneinander, mit einander zugewandten Rücken die Kegelräder KR1 und KR2 sitzen, mit denen die Kegelräder KR3 bzw. KR4 kämmen (vgl. Fig. 2), an den Enden von Kegelradwellen KW3 bzw. KW4 angeordnet sind, und auf denen jeweils ein walzenförmiges Stirnrad SR3 bzw. SR4 sitzt. Die Kegelradwellen KW3 und KW4 sind quer zur Achsrichtung der Tragwellen TW1 und TW2 der Walzringe WR1 und WR2 der in das Traggehäuse TG eingeschobenen Walzgerüste WGI bzw. WGII im Traggehäuse TG gelagert.As can be seen from Fig. 1, two roll stands WGI are in the support housing TG and WGII inserted. A bevel gear shaft KW is supported in the support housing TG, on the spaced apart, with their backs facing each other, the bevel gears KR1 and KR2 sit with which the bevel gears KR3 and KR4 mesh (cf. Fig. 2), are arranged at the ends of bevel gear shafts KW3 and KW4, and on each of which there is a cylindrical spur gear SR3 or SR4. The bevel gear shafts KW3 and KW4 are transverse to the axis direction of the support shafts TW1 and TW2 the rolling rings WR1 and WR2 of the rolling stands inserted into the support housing TG WGI or WGII stored in the TG housing.
Die Tragwellen TW1 und TW2 lagern, wie aus der Schnittdarstellung des Walzgerüstes WGI zu ersehen, verschiebbar geführt in Lagereinbaustücken LES1 und LES2. Sie tragen an ihren, der mit einem Pfeil E gekennzeichneten Einschubrichtung abgewandten Enden, hier fliegend angeordnet, das Walzringpaar WR1, WR2 und an dem anderen, der Kegelradwelle 4 und dem Stirnrad SR4 zugewandten Ende je ein Kronenrad KD1 bzw. KD2, diese kämmen mit dem Stirnrad SR4. Bei einer Verschiebung der Lagereinbaustücke LES1, LES2 gleiten die Zähne der Kronenräder KD1, KD2 in der Verzahnung des Stimrades SR4. Die die Anstellung der Walzringe WR1 und WR2 bewirkende Verschiebung der Lagereinbaustücke LES1 und LES2 im Walzgerüst WGI erfolgt über (vgl. auch Fig. 1) ein Spindelpaar SP, das in den Lagereinbaustücken LES1, LES2 gewindegeführt und über ein Schneckenradgetriebe mit Schneckenrädern SR und Schnecke SK antreibbar ist.The support shafts TW1 and TW2 are supported, as in the sectional view of the roll stand WGI can be seen, slidably guided in bearing chocks LES1 and LES2. They carry on their insertion direction marked with an arrow E. opposite ends, here flying, the rolling ring pair WR1, WR2 and on the other, facing the bevel gear shaft 4 and the spur gear SR4 End a crown gear KD1 or KD2, these mesh with the spur gear SR4. At a displacement of the bearing chocks LES1, LES2 slide the teeth of the Crown gears KD1, KD2 in the toothing of the spur gear SR4. The employment of the rolling rings WR1 and WR2 causing displacement of the bearing chocks LES1 and LES2 in the roll stand WGI are carried out via (see also FIG. 1) a pair of spindles SP, which is threaded in the bearing chocks LES1, LES2 and via a Worm gear with worm wheels SR and worm SK can be driven.
Dem Traggehäuse TG mit den beiden eingeschobenen Walzgerüsten WGI und WGII können weitere, nicht dargestellte Traggerüste nach- oder vorgeordnet werden, wobei die Enden der Kegelradwelle KW mit den Enden der Kegelradwellen der anzuschließenden Traggehäuse TG in üblicher Weise durch Kupplungen K verbunden werden. Die gesamte, so zusammengestellte und verbundene Walzgerüstanordnung wird über die durch die Kupplungen der Einzelabschnitte der Kegelradwellen gebildeten gemeinsamen Kegelradwelle über ein Getriebe GT von einem Motor MT angetrieben. The support casing TG with the two inserted roll stands WGI and WGII further, not shown supporting scaffolding can be arranged or subordinate, the ends of the bevel gear shaft KW with the ends of the bevel gear shafts the support housing TG to be connected in the usual way by couplings K get connected. The entire roll stand arrangement assembled and connected in this way is through the through the couplings of the individual sections of the bevel gear shafts formed common bevel gear shaft via a transmission GT from driven by a motor MT.
Anstelle der beschriebenen paarweisen Anordnung der Walzgerüste im Traggehäuse können diese auch einzeln in Reihe angeordnet und entsprechend über eine gemeinsame Kegelradwelle angetrieben werden. Instead of the paired arrangement of the roll stands in the support housing described can also be arranged individually in a row and accordingly be driven by a common bevel gear shaft.
