Abstract
Description
Die Erfindung betrifft ein Walzgerüst und ein Verfahren zur Einstellung des Walzgerüstes für den Walzbetrieb.The invention relates to a roll stand and a method for setting the roll stand for rolling operations.
Walzgerüste bestehen in der Regel aus zwei Walzenständern mit einer regelbaren Walzenanstellung und einer Hilfsanstellung zum Erreichen einer konstanten Passlinie. Durch die Konstruktion bedingt schnürt sich das Ständertenster bei Walzkraftbeaufschlagung ein. Bei unterschiedlichen Walzkräften liegen im Ständerfenster unterschiedliche Spiele zwischen Walzenständer und Walzeneinbaustücken vor.Roll stands usually consist of two roller stands with an adjustable roller adjustment and an auxiliary adjustment to achieve a constant pass line. By construction conditionally laces the stand window when rolling force is applied. Are at different rolling forces in the stand window different games between the roller stand and roller chocks.

Die Schrift
Der Erfindung liegt die Aufgaben zugrunde, ein neues Konstruktionsprinzip für Walzgerüste zu schaffen, die sich ohne andere Hilfsmittel immer wieder auf eine Konstante Passlinie einstellen und ein Verfahren zur Einstellung des Walzgerüstes zu entwickeln.The invention is based on the objects to create a new design principle for roll stands that can be used without Always set other aids to a constant pass line and to develop a method for adjusting the roll stand.
Gelöst wird diese Aufgabe erfindungsgemäß durch
die Kombination der folgenden Merkmale:
Das Walzgerüst, bestehend
aus vier Ständersäulen, die
mit einer Sohlplatte fest verankert sind und in denen axial unverschiebbar
geführte,
drehbeweglich gelagerte Zugspindeln angeordnet sind, deren obere und
untere Enden mit gegenläufigen
Gewinden versehen sind, die eine obere und untere Traverse aufnehmen
und über
die die Walzensätze
gegenläufig zueinander
verstellbar sind, wobei die Ständersäulen gleichzeitig
als Führungen
für Walzeneinbaustücke und
der Aufnahme von Biegeblöcken
dienen, und einem zwischen dem unteren Stützwalzeneinbausatz und der
unteren Traverse angeordneten Kurzhub-Anstellzylinder zur Walzkraftbeaufschlagung,
wobei durch eine getrennte Anordnung der Zugspindeln und der Walzeneinbaustücke in den
Ständersäulen eine
Trennung der Kraftübertragung
auf die Walzen und der Führung
der Walzeneinbaustücke
zu erreichen ist.According to the invention, this object is achieved by combining the following features:
The rolling stand, consisting of four stand columns, which are firmly anchored with a base plate and in which axially non-displaceable, rotatably mounted traction spindles are arranged, the upper and lower ends of which are provided with opposing threads that receive an upper and lower crossbeam and via which the Roller sets are adjustable in opposite directions to one another, the stand columns simultaneously serving as guides for roller chocks and the accommodation of bending blocks, and a short-stroke adjusting cylinder arranged between the lower support roller installation set and the lower cross member for applying rolling force, with a separate arrangement of the tension spindles and the roller chocks in the Stand columns a separation of the power transmission to the rollers and the leadership of the roller chocks can be achieved.
Des weiteren wird die Aufgabe durch ein Verfahren zur Einstellung des Walzgerüstes mit den Merkmalen des Patentanspruches 5 gelöst.Furthermore, the task is accomplished by a method for adjusting the rolling stand with the features of Claim 5 solved.
Weiterbildungen ergeben sich aus den Unteransprüchen.Further training results from the subclaims.
Der Erfindung liegt die Funktionsweise zugrunde, über ein Rechts- und Links- Gewinde gegenüberliegende Teile gleichmäßig (oder ungleichmäßig) aufeinander zu oder voneinander weg zu bewegen. Gleichzeitig wird die Funktion der Übertragung der Walzkraft von der Funktion "Führung der Walzeneinbaustücke" getrennt, wodurch Nachteile, wie Walzenständer-Fensterverengung, nicht mehr auftreten. Hierdurch wird auch die Neigung zu "Brummern" wesentlich beeinflusst.The invention is the mode of operation underlying, about a right and left thread opposing parts evenly (or unevenly) to move towards or away from each other. At the same time, the function the transfer the rolling force from the function "guidance of the Roll chocks "separately, which Disadvantages, such as roller frame window narrowing, no longer occur. This also has a significant influence on the tendency to "humming".
Die Erfindung soll nachfolgend an der Zeichnung erläutert werden, wobei die Figur eine schematische Seitenansicht, teilweise geschnitten, des Walzgerüstes zeigt.The invention is intended to: the drawing explained be, the figure is a schematic side view, partially cut the roll stand shows.
Die Konstruktion besteht im wesentlichen aus
vier geschweißten
Ständersäulen
Die Zugspindeln
Alle Komponenten sind einfach zu bearbeitende Fertigungsteile. Ein weitere Vorteil sind die niedrigen Gewichte der Einzelkomponenten zur Montage.All components are just too machining parts. Another advantage are the low ones Weights of the individual components for assembly.
