Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei vorzugsweise zum Strecken des Walzgutes dienenden Walzwerken wird den Walzen ein möglichst kleiner- Durchmesser gegeben, weil derartige Walzen erfahrungsgemäß eine große Streckwirkung auf das Gut ausüben.In the case of rolling mills, which are preferably used for stretching the rolling stock, the rollers as small a diameter as possible, because experience has shown that such rollers are a exert a great stretching effect on the material.
Derartige Walzen von kleinerem Durchmesser zeigen nun aber unter dem Gegendruck des Walzgutes eine starke Durchbiegung und müssen deshalb gestützt werden.However, such rollers with a smaller diameter now show under the counter pressure of the rolled stock is subject to strong deflection and must therefore be supported.
ίο Für diesen Zweck sind bereits über die ganze Länge der Walzen reichende, in den Gerüsten drehbar gelagerte Stützwalzen oder auch auf den Arbeitswalzen ruhende Stützschienen in Vorschlag gebracht worden, die bei der Drehung der Walzen eine Verschiebung erfahren.ίο For this purpose are already extending over the entire length of the rollers, in the Scaffolding rotatably mounted support rolls or support rails resting on the work rolls has been proposed that a shift in the rotation of the rollers Experienced.
Die bekannten Abstützwalzen sind nur für glatte Arbeitswalzen anwendbar, nicht aber für Walzen, die auf ihrer Länge verschiedene Durchmesser haben. Außerdem ergeben sich in den Zapfen der Abstützwalzen sehr starke Drucke und Reibungen, so daß besondere Kühlvorrichtungen vorgesehen werden müssen.The known backup rolls can only be used for smooth work rolls, but not for rolls that have different diameters along their length. Also arise Very strong pressure and friction in the journal of the support rollers, so that special Cooling devices must be provided.
Bei Anwendung von Stützschienen ist die Arbeitslänge durch die Länge der Schienen begrenzt, außerdem sind verwickelte Anordnungen für die Stützung und Führung der Schienen erforderlich.When using support rails, the working length is determined by the length of the rails limited, as well as intricate arrangements for the support and guidance of the Rails required.
Die Mängel der bekannten Einrichtungen sind gemäß vorliegender Erfindung dadurch beseitigt, daß als Stütze für die dünnen Arbeitswalzen Ringe benutzt werden, die sich, vorzugsweise unter Zwischenschaltung von Kugeln und Rollen, um feste Achsen des Walzengestelles drehen.The shortcomings of the known devices are in accordance with the present invention eliminates the fact that rings are used as supports for the thin work rolls, which preferably with the interposition of balls and rollers to rotate around fixed axes of the roller frame.
Auf der Zeichnung ist ein derartiges Walzwerk in mehreren Ausführungsformen dargestellt. Such a rolling mill is shown in several embodiments in the drawing.
Die Fig. 1 zeigt im senkrechten Längsschnitt, die Fig. 2 in Stirnansicht unter Fortlassung des einen Gestelles ein gemäß der Erfindung eingerichtetes Duowalzwerk mit fünf verschiedenen Kalibern, Fig. 3 und 4 die gleichen Darstellungen eines Triowalzwerks.Fig. 1 shows in vertical longitudinal section, FIG. 2 in an end view omitting the one frame according to FIG Invention set up duo rolling mill with five different calibers, Fig. 3 and 4 the same representations of a trio rolling mill.
Die Arbeitswalzen α von kleinem Durchmesser werden an den Arbeitsstellen gestützt durch Ringe b, die unter Zwischenschaltung von Kugeln c oder Rollen frei auf festen Achsen d des Gestelles e drehbar sind.The small-diameter work rolls α are supported at the work stations by rings b which, with the interposition of balls c or rollers, are freely rotatable on fixed axes d of the frame e.
Die Stützringe b haben einen im Verhältnis zu dem Durchmesser der Arbeitswalzen β sehr großen Durchmesser. Die Walzen und Ringe können sich frei abwickeln, wodurch eine große Kraftersparnis erzielt wird.The support rings b have a very large diameter in relation to the diameter of the work rolls β. The rollers and rings can unwind freely, which saves a lot of effort.
Anstatt die Stützringe genau senkrecht über oder unter den Arbeitswalzen anzuordnen, kann man sie auch, wie dies von Abstützrollen bekannt ist, seitlich von den Walzen anbringen, entsprechend der Richtung des von den Walzen ausgeübten Druckes. Dadurch wird das Hochgleiten der Arbeitswalzen auf den Stützringen verhindert.Instead of arranging the support rings exactly vertically above or below the work rolls, you can also, as is known from support rollers, to the side of the rollers according to the direction of the pressure exerted by the rollers. Through this the work rolls are prevented from sliding up on the support rings.
Arbeitet das Walzwerk immer nur nach einer Richtung, so genügt ein entsprechend seitlich angeordneter Stützring oder eine Stützringgruppe für jede Arbeitswalze. Arbeitet das Walzwerk aber abwechselnd nach verschiedenen Richtungen, so werden Stützringe zu beiden Seiten der Arbeitswalze angeordnet.If the rolling mill only ever works in one direction, a corresponding one is sufficient laterally arranged support ring or a support ring group for each work roll. Is working But if the rolling mill alternates in different directions, then there are support rings arranged on both sides of the work roll.
Bei dem Triowalzwerk nach Fig. 3 und 4In the trio rolling mill according to FIGS. 3 and 4
ist eine Abstützung der mittleren Arbeitswalze α durch Bunde k zwischen den einzelnen Stichen ermöglicht, die sich gegen entsprechende Bunde I an den äußeren Arbeitswalzen a1, az stützen.the middle work roll α can be supported by collars k between the individual stitches, which are supported against corresponding collars I on the outer work rolls a 1 , a z .
Die mittlere Arbeitswalze wird dadurch in sehr wirksamer Weise auch bei ungleicher Beanspruchung gestützt. Diese tritt schon dadurch ein, daß bei Beginn des Arbeitsvorganges zunächst nur der erste Stich und dann erst der Reihenfolge nach die anderen Stiche allmählich besetzt werden. Hier ist zugleich die Abstützung durch beiderseits der Arbeitswalzen a1 und α2- angeordnete Stützringe ver- anschaulicht.The middle work roll is supported in a very effective way, even when the load is uneven. This occurs because at the beginning of the work process only the first stitch and only then the other stitches are gradually occupied in sequence. At the same time, the support by support rings arranged on both sides of the work rolls a 1 and α 2 is illustrated here.
. Die Abstützwalzen können exzentrisch oder auch pronlförmig ausgebildet werden.. The support rollers can be designed to be eccentric or pronounced.
