Abstract

A mechanism alters the vertical position of the vertical rolls in a universal roll stand used for production of beams with different depths. With an asymmetric vertical cross section of the bearing mounting block (6), the vertical distances (d1; d2) of the slides (6a, 6b) for the bearing mounting block (6) from the horizontal longitudinal centre plane of the vertical roll (4) have different values.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Veränderung der Vertikalposition der Vertikalwalzen in Universalwalzgerüsten für das Walzen von Trägern unterschiedlicher Höhe. Beim Walzen von Trägern, insb. H-Trägern in Universalwalzgerüsten ist es notwendig, die Höhe der Gerüstmitte gegenüber der den Träger heran- und abtransportierenden Rollgangsoberkante, zur Anpassung an die jeweilige Trägerhöhe zu verschieben (halbe Trägerhöhe + Luftspalt). Diese wurde bisher mit Hilfe aufwendiger, einen verhältnismäßig großen Arbeitsaufwand erfordernder Keilverstellungen erreicht.The invention relates to a device for changing the vertical position of the vertical rolls in universal roll stands for the rolling of beams of different heights. When rolling girders, especially H-girders in universal rolling stands, it is necessary to shift the height of the center of the stand relative to the top edge of the roller table, which is carried in and out, to adapt to the respective girder height (half girder height + air gap). Up to now, this has been achieved with the aid of complex wedge adjustments which require a relatively large amount of work.

Der Erfindung liegt die Aufgabe zugrunde, den technischen Aufwand zu verringern und einen zusätzlichen Arbeitsaufwand überhaupt zu vermeiden.The invention has for its object to reduce the technical effort and to avoid any additional work.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die vertikalen Abstände der Ebenen der beiden Gleitführungen des Lagereinbaustücks von der horizontalen Längsmittenebene der Vertikalwalze bei asymmetrischer Ausbildung des vertikalen Querschnitts des Gehäuses des Lagereinbaustücks unterschiedlich groß bemessen sind, d.h. ein Lagereinbaustück mit asymmetrischem Querschnitt verwendet wird. In diesem Fall müssen für jede der zu walzenden unterschiedlichen Trägerhöhen allerdings entsprechende Lagereinbaustücke wechselweise ein- und ausgebaut werden.This object is achieved according to the invention in that the vertical distances of the planes of the two sliding guides of the bearing chock from the horizontal longitudinal center plane of the vertical roller are of different sizes with asymmetrical design of the vertical cross section of the housing of the bearing chock, ie a bearing chock with asymmetrical cross section is used. In this case, however, corresponding bearing chocks must be installed and removed alternately for each of the different beam heights to be rolled.

Die Erhöhung des Abstandes zwischen Rollgang und Vertikalwalzenmitte kann auch, wie die Erfindung weiter vorsieht, durch, auf die horizontalen Führungsflächen der Lagereinbaustücke der Vertikalwalzen des Universalgerüstes aufsetz- und festlegbare Beilageleisten gelöst werden. Die lagereinbaustücke mit ihnen die Vertikalwalzen werden durch diese Anordnung, auf den Beilageleisten gleitend mit einem, durch deren Stärke bestimmten vergrößerten Abstand über der Rollgangsoberkante bewegt. Einer Verstellung des gesamten Gerüstes bedarf es dabei nicht.The increase in the distance between the roller table and the vertical roller center can also, as the invention further provides, be solved by inserting and fixing insert strips on the horizontal guide surfaces of the bearing chocks of the vertical rollers of the universal stand. The bearing chocks with them the vertical rollers are moved by this arrangement, sliding on the side ledges with an increased distance determined by their strength above the top of the roller table. It is not necessary to adjust the entire scaffolding.

Um den Kraftschluß im vertikalen Teil des Universalgerüstes in einer gemeinsamen Höhe zu halten, können, wie die Erfindung schließlich vorsieht, die den Walzdruck aus den Vertikalwalzen aufnehmenden Quertraversen des Universalwalzgerüstes in diesem vertikal hubverstellbar angeordnet werden.In order to keep the frictional connection in the vertical part of the universal stand at a common height, as the invention finally provides, the transverse beams of the universal roll stand, which absorb the rolling pressure from the vertical rolls, can be arranged vertically adjustable in this.

Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail with reference to the embodiment shown in the drawing.

Die Zeichnung zeigt die Ansicht auf einen, teilweise geschnittenen Ausschnitt eines Universalwalzgerüstes, von der Seite quer zur Walzrichtung gesehen. Aus der Zeichnung ist zu ersehen, daß im Gerüstrahmen UG des Universalwalzgerüstes die Lagereinbaustücke 1 und 2 der oberen und der unteren Horizontalwalzen 1a, 2a, vertikal geführt sind. Die, nicht dargestellten, Träger werden über den Rollgang 3 in das Walzgerüst zwischen die beiden Horizontalwalzen geführt und jeweils seitlich von den Vertikalwalzen beaufschlagt. Diese Vertikalwalzen sind in der Ausbildung links von der vertikalen Mittellinie der Zeichnung mit 4 und rechts von der Mittellinie mit 5 bezeichnet. Die Vertikalwalze 4 lagert in einem Lagereinbaustück 6 und die mit 5 bezeichnete Vertikalwalze lagert in einem Lagereinbaustück 7. Der vertikale Abstand der Längsmitte LM 5 der (rechten) Vertikalwalze von der Rollgangsoberkante RK ist durch die Beilageleiste 8 auf die Führungsflächen 7a und 7b bestimmt; er kann durch den Austausch dieser Beilageleisten 8 gegen solche mit anderen Stärken oder weiteren Beilagen verändert werden.The drawing shows the view of a partially cut section of a universal rolling stand, seen from the side transverse to the rolling direction. From the drawing it can be seen that the bearing chocks 1 and 2 of the upper and lower horizontal rolls 1a, 2a are guided vertically in the scaffold frame UG of the universal roll stand. The carriers, not shown, are guided over the roller table 3 into the roll stand between the two horizontal rollers and are each laterally loaded by the vertical rollers. These vertical rollers are designated 4 on the left of the vertical center line of the drawing and 5 on the right of the center line. The vertical roller 4 is supported in a bearing chock 6 and the vertical roller designated 5 is supported in a bearing chock 7. The vertical distance of the longitudinal center LM 5 of the (right) vertical roller from the roller table top edge RK is determined by the shim 8 on the guide surfaces 7a and 7b; he can can be changed by exchanging these insert strips 8 for those with different strengths or additional supplements.

Die vertikalen Abstände d1 und d2 der horizontalen Längsmittenebene LM 4 der Vertikalwalze 4 von den Ebenen der Führungsflächen 6a und 6b sind hier unterschiedlich groß bemessen und führen zu einer asymmetrischen Ausbildung des Vertikalquerschnitts des Gehäuses des Lagereinbaustücks 6 unter Verkleinerung des Abstandes der Längsmitte LM 4 von der Rollgangsoberkante RK.The vertical distances d1 and d2 of the horizontal longitudinal center plane LM 4 of the vertical roller 4 from the planes of the guide surfaces 6a and 6b are dimensioned differently here and lead to an asymmetrical design of the vertical cross section of the housing of the bearing insert 6 while reducing the distance of the longitudinal center LM 4 from the RK top roller table.
