Description

Anordnung der Stützwalzen bei Umkehrwalzwerken mit vier oder sechs Walzen Die Anordnung der Stützwalzen bei den bisherigen Ausführungen der vier und sechs Walzenwalzwerke ist eine gleichmäßig um die Vertikalachse verteilte (Abb. t und z).Arrangement of the backup rolls in reversing mills with four or six Rollers The arrangement of the backup rolls in the previous versions of the four and six roller mills is one evenly distributed around the vertical axis (Fig. t and z).

Um eine gleich große Belastung der Stützwalzen b, c, b2, c, zu erreichen, wird nach früheren Vorschlägen deren Mittelebene S, je nach der Arbeitsbedingung, ob eine oder beide Arbeitswalzen a, a1, ob diese vorwärts oder rückwärts drehend angetrieben werden, so gelegt, daß sie in die Richtung der Resultierenden R aus Walzdruck w und Walzkraft T fallen, wodurch aus -der Richtung der Resultierenden R (Abb. 6) die Richtung von S bestimmt ist.In order to achieve the same load on the back-up rolls b, c, b2, c, according to previous proposals, their center plane S, depending on the working condition, whether one or both work rolls a, a1, whether they are driven to rotate forwards or backwards, so placed that they fall in the direction of the resultant R of rolling pressure w and rolling force T, whereby the direction of S is determined from the direction of the resultant R (Fig. 6).

Bei einem Umkehrwalzwerk, bei dem .der ursprüngliche Ein- .und Austritt des Walzgutes bei jedem folgenden Strich vertauscht wird, wird auch die Lage der Resultierenden und somit .die Mittelebene S j edesmal eine andere Lage zur Vertikalachse y (Abb. 6) einnehmen müssen. In den Abb. 3, 4 und 5 ist dies durch Vergleich der ausgezogenen mit der punktierten Lage der Stützwalzen zu ersehen. Es ist demnach notwendig, .daß die Stützwalzen um die Achse ihrer Arbeitswalzen schwenkbar eingerichtet sind, falls gleich große Stützdrücke erreicht werden sollen.In a reversing mill, where. The original entry and exit of the rolled stock is swapped with each subsequent line, the position of the Resultant and thus .the central plane S each time a different position to the vertical axis y (Fig. 6). In Figs. 3, 4 and 5 this is done by comparing the to see the solid line with the dotted position of the back-up rollers. It is accordingly necessary, .that the backup rolls are set up to be pivotable about the axis of their work rolls if equally large support pressures are to be achieved.

Die Abb. 3 und 4. veranschaulichen das oben Gesagte, wenn nur eine Arbeitswalze a angetrieben wird, Abb. 5 dagegen, wenn die beiden Arbeitswalzen a, a, angetrieben werden.Figs. 3 and 4. illustrate what has been said above, if only one Work roll a is driven, Fig. 5, however, when the two work rolls a, a, be driven.

PATENTANSPRUCH: Anordnung der Stützwalzen bei Umkehrwalzwerken mit vier oder sechs Walzen, wobei eine oder beide Arbeitswalzen angetrieben werden, .dadurch gekennzeichnet, daß die Stützwalzenpaare so schwenkbar um ihre Arbeitswalzen eingerichtet sind und entsprechend der jeweiligen Drehrichtung der Arbeitswalzen so eingestellt werden, daß zur Erzielung gleicher Stützdrücke und zur Verhinderung vonWalzenklemmungen die Ebenen, die die Winkel zwischen den durch die Achsen ,der Stützwalzen (b, c und b" c,) und die Achsen der zugehörigen Arbeitswalzen (a, a,) ge- legten Ebenen halbieren, nach der Seite geneigt sind, daß sie in die Richtung der Resultierenden (R) aus dem Walzdruck (w) .und Walzkraft (T) fallen.Claim: arrangement of the back-up rolls in reversing mills with four or six rolls, with one or both work rolls being driven, characterized in that the back-up roll pairs are set up so that they can be pivoted about their work rolls and are set according to the respective direction of rotation of the work rolls in such a way that to achieve the same Support pressures and to prevent roll jamming the planes that bisect the angles between the planes formed by the axes, the support rolls (b, c and b " c,) and the axes of the associated work rolls (a, a,) , to the side are inclined to fall in the direction of the resultant (R) from the rolling pressure (w). and rolling force (T).
