Description
Die Erfindung betrifft nach Anspruch 1 eine Kompakt-Walzblockanordnung für das Walzen von, nebeneinander
aus einer Vorverarbeitungsanlage in parallelen Linien herangeführten
Walzgutsträngen, bei der die Walzblöcke in Walzrichtung, altemierend aufeinander
folgend Vertikal- bzw. Horizontalwalzenpaare aufweisen, die über Winkelgetriebe
mit parallel zu den Walzlinien verlaufend gelagerten Antriebswellen gekuppelt
sind.According to
Gattungsgemäße Walzgerüstanordnungen dieser Art werden in Walzenstraßen für Draht und Feineisen verwendet (GB-A 1 128 157). Die Drahtstränge treten dabei mit verhältnismäßig großen Seitenabständen aus den zuführenden Draht-Vorverarbeitungsstraßen aus. Diese Seitenabstände erlauben die Anordnung der Antriebswellen und auch mehrerer Antriebswellen für die Walzblöcke sowie dazu notwendige Winkelgetriebe ohne große Schwierigkeiten.Generic roll stand arrangements of this type are used in rolling mills for wire and fine iron used (GB-A 1 128 157). The wire strands occur with relatively large side distances from the feeding wire preprocessing lines. This Side distances allow the arrangement of the drive shafts and also several Drive shafts for the rolling blocks as well as the necessary bevel gear without great difficulties.
Beim sogenannten Heißwalzen von Drahtsträngen, bei dem die aus einer Stranggußanlage austretenden Messen Stränge unmittelbar nach ihrem Austreten in die Walzgerüstanordnung eingebracht werden, ist der Abstand zwischen zwei parallelen Strängen betriebsbedingt sehr klein, mit der Folge, daß die Reihen der Walzblöcke mit entsprechend geringem Seitenabstand voneinander angeordnet werden müssen und damit für die Antriebswellen und die, mit diesen zu kuppelnden Walzgerüste sehr wenig Platz zur Verfügung steht.In the so-called hot rolling of wire strands, in which the from a continuous casting plant emerging strands immediately after they emerge into the Roll stand arrangement are introduced, is the distance between two parallel Strands very small for operational reasons, with the result that the rows of Rolling blocks arranged with a correspondingly small lateral distance from one another must be and thus for the drive shafts and those to be coupled with them Roll stands very little space is available.
Der Erfindung liegt die Aufgabe zugrunde, eine Walzblockanordnung mit deren Antriebswellen und den Verbindungselementen zu schaffen, die diesem engen Einbauverhältnis Rechnung trägt.The invention has for its object a roll block assembly with the Drive shafts and the connecting elements that create this tight Installation ratio takes into account.
Diese Aufgabe wird dadurch gelöst, daß drei gemeinsam angetriebene Antriebswellen für die Walzen, in Achsrichtung gesehen zueinander so positioniert sind, daß die Achsmitte einer der Antriebswellen im oberen Eckpunkt eines aufrechtstehenden, gleichschenkligen Dreiecks und die Achsmitten der beiden anderen Antriebswellen in den beiden unteren Eckpunkten dieses Dreiecks liegen. Dabei können, wie die Erfindung weiter vorsieht, die, Horizontalwalzenpaare aufweisenden Walzblöcke mit der Antriebswelle gekuppelt sein, deren Achsmitte in dem oberen Eckpunkt des Dreiecks liegt und die, Vertikalwalzenpaare aufweisenden Walzblöcke mit den Antriebswellen gekuppelt sein, deren Achsen in den beiden unteren Eckpunkten des Dreiecks liegen. Die, Horizontatwatzenpaare aufweisenden Walzblöcke werden zweckmäßig, um ihre Antriebswellenachse nach unten geneigt und die, Vertikalwalzenpaare aufweisenden Walzblöcke um ihre Antriebswellenachse nach außen geneigt angeordnet. Dabei kann die Anordnung erfindungsgemäß so getroffen werden, daß die beiden Antriebswellen, deren Achsmitten in den beiden äußeren Eckpunkten des gleichschenkligen Dreiecks liegen, jeweils mit einer gleich großen Anzahl von Walzblöcken mit Horizontalwalzenpaaren antriebsverbunden sind und die Antriebswellen, deren Achsmitte im oberen Eckpunkt des Dreiecks liegt mit den doppelten dieser Zahl von Walzbföcken ist, wobei diese Walzblöcke mit ihren Horizontalwalzenpaaren alternierend der einen und der anderen der beiden Walzlinien zugeordnet sind. Die Antriebswellen der Walzblöcke werden, wie die Erfindung weiter vorschlägt, gemeinsam von einem Motor angetrieben, wobei die drei Antriebswellen je ein Stirnrad aufweisen, das mit einem, auf der Motorwelle sitzenden Stimrad kämmt. Die Achsmitten der oberen Antriebswelle und die der beiden unteren Antriebswellen und die Mittenlinien der Drahtsträngen können erfindungsgemäß so positioniert werden, daß sie in den Eckpunkten eines gleichmäßigen Fünfecks verlaufen.This object is achieved in that three jointly driven drive shafts for the rolls, positioned in relation to one another in the axial direction, that the center of the axis of one of the drive shafts in the upper corner of an upright, isosceles triangle and the center of the axles of the other two drive shafts lie in the two lower corners of this triangle. there can, as the invention further provides, having the horizontal roller pairs Roll blocks to be coupled to the drive shaft, the center of its axis in the the upper corner point of the triangle and the vertical roller pairs Rolling blocks to be coupled to the drive shafts, the axes of which in the two lower corner points of the triangle. The ones exhibiting pairs of horizontal wafers Rolling blocks are useful to down their drive shaft axis inclined and the roll blocks having vertical roll pairs around their drive shaft axis arranged inclined outwards. The arrangement can be according to the invention so that the two drive shafts, the center of their axes lie in the two outer corner points of the isosceles triangle, each with an equal number of billets with pairs of horizontal rolls are connected to the drive and the drive shafts, the center of which is in the upper Corner point of the triangle is twice that number of rams, these blocks with their horizontal roller pairs alternately one and the other of the two rolling lines are assigned. The drive shafts of the Roll blocks, as the invention further proposes, together by one Motor driven, the three drive shafts each having a spur gear, the combs with a spur wheel sitting on the motor shaft.

angetrieben wird, wobei zwei der Antriebswellen 3 und 4 sich als auf der Höhe der
Basiswinkel des oben erwähnten gleichschenkligen Dreiecks befinden und die
dritte Welle 2 sich an der Spitze des gleichschenkligen Dreiecks befindet, wobei
die beiden Antriebswellen 3, 4 die jeweiligen Walzblöcke VR und VL auf der rechten
und der linken Seite mit den Walzrollenpaaren RR für vertikales Walzen nach
rechts und nach links VRR nach oben antreiben, und wobei die obere Antriebswelle
