Description

Walzwerk zum Auswalze Draht, Fein- und Formeisen Es ist bekannt, daß beim Walzen von Eisen und Metall die Streckwirkung mit der Durchmesserabnahme der Walzen zunimmt. Um dabei die Starrheit der Walzen zu wahren, werden Stützwalzen verwendet, die, parallelachsig gelagert, das Arbeitswalzenpaar zu beiden Seiten in der Druckebene abstützen, um eine Durchbiegung der Arbeitswalzen zu verhindern. Sofern es sich um das Walzen von Blechen, Streifen, Flacheisen oder Knüppeln mit ebenen Begrenzungen handelt, kann die arbeitende Umfangsfläche der Arbeitswalze gleichzeitig als Abstützfläche für die Stützwalze dienen. Bei einem kalibrierten Ballenumfange ist diese Art Abstützung durch den schädlichen Einfluß auf die Kalibergenauigkeit jedoch nicht statthaft. Die Abstützungspunkte dürfen bei solchen Walzen daher nicht mit der Kaliberbahn zusammentreffen. Sie Zi=erden daher in der gewünschten Anzahl symmetrisch zur Ballenmitte zwischen den Kalibern verteilt. Abgestützte Kaliberwalzen dieser Art sind bisher nur für fliegend gelagerte, nicht aber für beiderseitig in Lagern laufende Arbeitswalzen bekanntgeworden. Gerade diese Walzenlagerung ermöglicht erst die dauerhafte Wahrung der ursprünglichen Stichform bei der Massenherstellung auf einer im übrigen bekannten Gerüstform entsprechend der Zeichnung.Rolling mill for rolling wire, fine and shaped iron It is known that when rolling iron and metal the stretching effect with the decrease in diameter Rolling increases. In order to maintain the rigidity of the rolls, back-up rolls are used used, which, mounted parallel to the axis, the pair of work rolls on both sides Support in the printing plane to prevent the work rolls from sagging. Unless it involves rolling sheet metal, strips, flat iron or billets is flat boundaries, the working peripheral surface of the work roll at the same time serve as a support surface for the support roller. With a calibrated Bale circumference is this type of support due to the harmful influence on the accuracy of the caliber however not allowed. The support points must therefore not be used in such rolls meet with the Kaliberbahn. You therefore ground the desired number distributed symmetrically to the center of the barrel between the calibers. Supported caliber rollers of this type are so far only for cantilevered, but not for both sides in Bearings running work rolls become known. It is precisely this roller bearing that makes it possible only the permanent preservation of the original stitch shape in mass production on a otherwise known frame form according to the drawing.

Erfindungsgemäß kommt nun die Abstützung derart zur Wirkung, daß jeweils ein ringförmiger Vorsprung der Stützwalze sein Widerlager meiner .entsprechenden ringförmigen Ausdrehung in der Arbeitswalze findet. Für diesen Zusammenschluß ist eine paßgerechte Form gewählt, derart, daß neben der ,gegenseitigen Abstützung in der Richtung des Walzdrucks auch die axiale Lage zwischen Arbeits- und Stützwalze durchaus gesichert ist.According to the invention, the support comes into effect in such a way that each an annular projection of the back-up roller will be an abutment of my. corresponding finds annular recess in the work roll. For this association is chosen a fitting shape, such that in addition to the mutual support in the direction of the rolling pressure also the axial position between the work and back-up roll is well secured.

Die Abb. i bis 5 der Zeichnung sollen als Musterbeispiel dienen.Figs. I to 5 of the drawing are intended to serve as an example.

Abb. i zeigt die Arbeits- und Stützwalzen im Aufriß.Fig. I shows the work and backup rolls in elevation.

Abb. 2 ist eine Seitenansicht von Abb. i. Abb. 3 zeigt den Antrieb der unteren Arbeitswalze durch den Hauptmotor mit Hilfsantrieb der oberen Stützwalze.Fig. 2 is a side view of Fig. I. Fig. 3 shows the drive the lower work roll by the main motor with auxiliary drive of the upper backup roll.

Abb. q. den Stützwalzenantrieb durch zwei gleich große Motoren, Abb.5 die Abstützung zwischen Arbeits-und Stützwalze in größerem Maßstab.Fig.q. the back-up roll drive by two motors of the same size, Fig.5 the support between the work and back-up roll on a larger scale.

Das kalibrierte Arbeitswalzenpaar i und liegt zwischen den Abstützwalzen 3 und q.. In die keilförmigen Eindrehungen 5 an den Arbeitswalzen greifen die ringförmigen Vorsprünge 6 der Stützwalzen ein. Die Antriebsmotoren 7, 8 und 9 sowie io sind unmittelbar mit den Walzen gekuppelt. Durch diese paßgerechte Art der Abstützung der Arbeitswalzen wird der axiale Walzdruck auf die Stützwalzen unmittelbar übertragen, so daß die Stirnflächen der Arbeitswalzen entlastet werden. Dadurch wird der Verschleiß der Widerlager an den Einbaustücken verringert und die Verlagerung der Arbeitswalzen in der waagerechten Ebene vermieden. Die axialen Kräfte «erden dagegen von den großen Stirnflächen der Stützwalzen aufgenommen, wodurch eine Gewähr für die dauernde Beibehaltung der von vornherein ausgerichteten Arbeitswalzen zueinander mit genauester Einstellung gegeben ist und damit auch die Beibehaltung einer einwandfreien Form, des Kaliberumfangs durch den auf ein Kleinstmaß beschränkten Verschleiß.The calibrated work roll pair i and lies between the support rolls 3 and q .. In the wedge-shaped indentations 5 on the work rolls engage the ring-shaped Projections 6 of the support rollers. The drive motors 7, 8 and 9 and io are direct coupled with the rollers. With this fitting type of support for the work rolls the axial rolling pressure is transmitted directly to the backup rolls, so that the End faces of the work rolls are relieved. This will reduce the wear and tear of the Reduced abutment on the chocks and the shifting of the work rolls avoided in the horizontal plane. The axial forces, on the other hand, are grounded by the great ones End faces of the backup rolls added, which guarantees permanent retention of the work rolls aligned from the start with the most precise adjustment is given and thus also the retention of a perfect shape, the caliber circumference due to the limited wear and tear.
