Description

Die vorliegende Erfindung betrifft ein ständerloses Walzgerüst, mit mindestens zwei Arbeitswalzen, die in Walzenlagern gelagert sind und sich längs je einer Walzenachse erstrecken, wobei die Walzen einen Walzspalt und die Walzenachsen eine Walzebene definieren, wobei die Walzebene beide Walzenachsen enthält, wobei die Walzenlager über zwei Gruppen von Verbindungselementen miteinander verbunden sind, wobei die Gruppen auf je einer Seite der Walzebene angeordnet sind, wobei die Gruppen in einer Verstellrichtung über eine Verstellweglänge verstellbar sind, wobei mindestens eine der Gruppen unter Last mittels eines Verstellantriebs in der Verstellrichtung über eine Lastweglänge verstellbar ist, wobei die Lastweglänge erheblich kleiner ist als die Verstellweglänge.The present invention relates to a standless roll stand, with at least two work rolls, which are stored in roller bearings and each extend along a roller axis, the rollers define a roll gap and the roll axes define a roll plane, the roller plane contains both roller axes, the roller bearings connected to each other via two groups of connecting elements are, with the groups on each side of the roller plane are arranged, the groups in an adjustment direction an adjustment path length are adjustable, with at least one of the Groups under load using an adjustment drive in the direction of adjustment is adjustable over a load path length, the load path length is considerably smaller than the adjustment path length.

Derartige Walzgerüste sind bekannt. Bei den ständerlosen Walzgerüsten des Standes der Technik sind die Verbindungselemente durch dem Walzgerüst zugeordnete Verstellorgane über die gesamte Verstellweglänge verstellbar. Diese Verstellbarkeit ist auch erforderlich, um am Walzgerüst Umbauarbeiten, z.B. einen Walzenwechsel, vornehmen zu können. Im Betrieb hingegen ist lediglich erforderlich, den Walzspalt - lastfrei oder unter Last - um wenige Millimeter anstellen zu können.Roll stands of this type are known. With the stand-less mill stands the prior art are the connecting elements by the Adjustment elements assigned to the roll stand over the entire length of the adjustment path adjustable. This adjustability is also necessary to carry out conversion work on the rolling stand, e.g. change the roller to be able to. In operation, on the other hand, only the Adjust the roll gap - load-free or under load - by a few millimeters to be able to.

Die Aufgabe der vorliegenden Erfindung besteht darin, bei gleicher Leistungsfähigkeit die Kosten und das Gewicht eines Walzgerüsts zu verringern. The object of the present invention is the same Performance increases the cost and weight of a roll stand reduce.

Die Aufgabe wird dadurch gelöst, daß die Gruppen bezüglich des die Lastweglänge übersteigenden Teils der Verstellweglänge antriebslos ausgebildet sind. Der Erfindung liegt dabei die Erkenntnis zugrunde, daß die Verstellung über die gesamte Verstellweglänge durch ein Werkzeug erfolgen kann, welches an das Walzgerüst ansetzbar ist. Das Verstellwerkzeug wird dann für mehrere Walzgerüste nur einmal benötigt, so daß das einzelne Walzgerüst aufgrund des Fehlens eines Verstellantriebs für die gesamte Verstellweglänge leichter und eine Gruppe von z.B. fünf oder zehn Walzgerüsten mit nur einem gemeinsamen Verstellwerkzeug für die gesamte Gruppe von Walzgerüsten kostengünstiger ist als wenn jedes Walzgerüst der Gruppe mit einem eigenen Verstellantrieb für die gesamte Verstellweglänge versehen wäre.The task is solved in that the groups regarding the Part of the adjustment path length exceeding the load path length has no drive are trained. The invention is based on the finding that the adjustment over the entire length of adjustment by Tool can be made, which can be attached to the roll stand. The adjustment tool is then only once for several roll stands needed so that the single roll stand due to the lack of a Actuator for the entire length of adjustment and lighter Group of e.g. five or ten roll stands with only one common Adjustment tool for the entire group of roll stands is cheaper than if every rolling stand in the group had one provided its own adjustment drive for the entire length of the adjustment path would.

Die andere der Gruppen von Verbindungselementen kann mittels eines weiteren Verstellantriebs ebenfalls über die Lastweglänge - lastfrei oder unter Last - verstellbar sein. Das Walzgerüst ist aber noch leichter und noch kostengünstiger, wenn die andere der Gruppen völlig antriebslos ausgebildet ist. Insbesondere in diesem letzten Fall wird zum Einstellen des Walzspalts unter Last nur die eine Gruppe von Verbindungselementen verstellt, während die andere Gruppe unverstellt bleibt.The other of the groups of connecting elements can be by means of a other actuators also over the load path length - load-free or adjustable under load. The roll stand is still easier and more affordable if the other of the groups is completely unpowered. Especially in this last one Fall is only one for setting the roll gap under load Group of fasteners adjusted while the other group remains undisguised.

Der Verstellantrieb zum Verstellen der Verbindungselemente unter Last kann wahlweise als Hydraulikzylindereinheit oder als Elektromotor ausgebildet sein. Wenn der Verstellantrieb als Elektromotor ausgebildet ist, kann über einen einzigen Motor - gegebenenfalls unter Verwendung von Getrieben - je eine Gruppe von Verbindungselementen verstellt werden.The adjustment drive for adjusting the connecting elements under Load can either be a hydraulic cylinder unit or an electric motor be trained. If the adjustment drive as an electric motor is formed, if necessary, via a single motor using gears - a group of fasteners each be adjusted.

Die vorliegende Erfindung umfaßt ferner ein Verstellwerkzeug zum Ansetzen an ein ständerloses Walzgerüst, wobei das Verstellwerkzeug zum gleichzeitigen Verstellen aller Verbindungselemente des Walzgerüsts pro Verbindungselement je ein angetriebenes Verstellorgan aufweist, durch welches die Verbindungselemente des Walzgerüsts über ihre gesamte Verstellweglänge verstellbar sind. The present invention further includes an adjustment tool for Attach to a stand-free roll stand, using the adjustment tool for simultaneous adjustment of all connecting elements of the roll stand one driven adjusting element per connecting element has through which the connecting elements of the roll stand over their entire length of adjustment are adjustable.

Das Verstellwerkzeug ist konstruktiv besonders einfach aufgebaut, wenn die Verstellorgane starr miteinander gekuppelt sind und den Verstellorganen ein gemeinsamer Antrieb zugeordnet ist, der vorzugsweise als Elektromotor ausgebildet ist.The adjustment tool has a particularly simple design, if the adjusting elements are rigidly coupled together and the Adjusting elements is assigned a common drive, which is preferably is designed as an electric motor.

Gemäß den Fig. 1 bis 3 weist ein ständerloses Kombi-Walzgerüst zum Walzen von Knüppeln und dergleichen zwei Walzen 1 auf, welche sich entlang horizontaler Walzenachsen 2 erstrecken. Die Walzenachsen 2 verlaufen parallel zueinander und definieren dadurch eine Walzebene 3. Innerhalb der Walzebene 3 definieren die Walzen 1 einen Walzspalt 4.According to FIGS. 1 to 3, a stand-less combination rolling stand has Rolling billets and the like two rolls 1, which are extend along horizontal roller axes 2. The roller axes 2 run parallel to each other and thereby define a roll plane 3. Within the roller plane 3, the rollers 1 define one Roll gap 4.

Die Walzen 1 sind in Walzenlagern 5 gelagert, die über zwei Gruppen 6, 7 von Verbindungselementen 8 miteinander verbunden sind. Wie ersichtlich ist, sind die Gruppen 6, 7 auf je einer Seite der Walzebene 3 angeordnet. Die Verbindungselemente 8 sind im Bereich der Walzenlager 5 mit gegenläufigen Gewindespindeln 9 versehen. Die Verbindungselemente 8 und damit auch die Gruppen 6, 7 von Verbindungselementen 8 sind in einer Verstellrichtung z über eine Verstellweglänge von z.B. 40 cm durch Drehen verstellbar. Die Verbindungselemente 8 sind an ihren oberen Enden 10 mit Vierkantprofilen versehen, die mittels eines später noch zu beschreibenden Verstellwerkzeugs verstellbar sind. Die Verbindungselemente 8 selbst aber sind antriebslos ausgebildet.The rollers 1 are stored in roller bearings 5, which have two groups 6, 7 of connecting elements 8 are connected to one another. How can be seen, the groups 6, 7 on each side of the Roll plane 3 arranged. The connecting elements 8 are in the area the roller bearing 5 is provided with counter-rotating threaded spindles 9. The Connecting elements 8 and thus also the groups 6, 7 of connecting elements 8 are in an adjustment direction z over an adjustment path length from e.g. 40 cm adjustable by turning. The fasteners 8 are at their upper ends 10 with square profiles provided by means of a later to be described Adjusting tool are adjustable. The connecting elements 8 themselves but are non-powered.

Beim Betrieb des Walzgerüsts ist eine Einstellung des Walzspalts 4 um wenige Millimeter, z.B. 5 mm, erforderlich. Diese Verstellung muß unter Last erfolgen können. Um diese Verstellung zu bewerkstelligen, ist der einen Gruppe 6 von Verbindungselementen 8 ein Verstellantrieb 11 zugeordnet. Im Ausführungsbeispiel besteht der Verstellantrieb 11 aus zwei Hydraulikzylindereinheiten 12, wobei jedem Verbindungselement 8 der Gruppe 6 eine eigene Hydraulikzylindereinheit 12 zugeordnet ist. Alternativ könnte die Verstellung auch durch Elektromotoren erfolgen. Eine Verstellung durch Elektromotoren wäre insofern vorteilhaft, als beide Verbindungselemente 8 der Gruppe 6 von einem gemeinsamen Elektromotor synchron verstellt werden könnten.When operating the roll stand, an adjustment of the roll gap is required 4 by a few millimeters, e.g. 5 mm, required. This adjustment must be able to take place under load. To accomplish this adjustment, the one group 6 of connecting elements 8 is an adjustment drive 11 assigned. In the exemplary embodiment, the Adjustment drive 11 from two hydraulic cylinder units 12, wherein each connecting element 8 of group 6 has its own hydraulic cylinder unit 12 is assigned. Alternatively, the adjustment could also be made done by electric motors. An adjustment by electric motors would be advantageous in that both connecting elements 8 of the Group 6 adjusted synchronously by a common electric motor could become.

Im Ausführungsbeispiel ist die andere Gruppe 7 von Verbindungselementen 8 völlig antriebslos ausgebildet. Das Einstellen des Walzspalts 4 unter Last kann also zwangsläufig nur dadurch erfolgen, daß die eine Gruppe 6 von Verbindungselementen 8 verstellt wird, während die andere Gruppe 7 von Verbindungselementen 8 unverstellt bleibt. Es wäre aber auch möglich, auch die andere Gruppe 7 von Verbindungselementen 8 mit hydraulischen oder elektromotorischen Verstellantrieben zu versehen, so daß in diesem Fall auch die andere Gruppe 7 unter Last über die Lastweglänge verstellbar wäre.In the exemplary embodiment, the other group is 7 of connecting elements 8 designed completely without drive. Setting the Roll gap 4 under load can inevitably only take place by that a group 6 of connecting elements 8 is adjusted, while the other group 7 of connecting elements 8 is undisguised remains. But it would also be possible to use the other group 7 of Connecting elements 8 with hydraulic or electromotive To provide actuators, so that in this case the other Group 7 would be adjustable under load over the load path length.

Durch die Hydraulikzylindereinheiten 12 sind die Verbindungselemente 8 der einen Gruppe 6 um eine Lastweglänge von z.B. 10 mm verstellbar. Aufgrund der symmetrischen Anordnung der Gruppen 6, 7 links und rechts vom Walzspalt 4 kann dieser folglich um die Hälfte von 10 mm, also 5 mm, verstellt werden. Dies ist für den ordnungsgemäßen Betrieb des Walzgerüsts hinreichend. Im Ergebnis wird das Walzgerüst durch das Verstellen der Hydraulikzylindereinheiten 12 also in einem Winkelbereich α verstellt, welcher eine Verstellung des Walzspalts 4 bewirkt. Die Feineinstellung des Walzspalts 4 erfolgt also nach dem einseitigen Verstellprinzip einer Schwinge. Der Walzspalt 4 wird dabei durch die einseitige hydraulische Anstellung der einen Gruppe 6 verändert, während die andere Gruppe 7 leicht geneigt wird. Die Größe des Anstellwinkels α erlaubt die Justierung im angegebenen Größenbereich von 5 bzw. 10 mm.Through the hydraulic cylinder units 12 are the connecting elements 8 of one group 6 by a load path length of e.g. 10 mm adjustable. Due to the symmetrical arrangement of groups 6, 7 on the left and to the right of the nip 4 this can therefore be reduced by half 10 mm, i.e. 5 mm, can be adjusted. This is for the proper one Sufficient operation of the roll stand. As a result, the mill stand by adjusting the hydraulic cylinder units 12 in one Adjusted angular range α, which is an adjustment of the roll gap 4 causes. The fine adjustment of the roll gap 4 is therefore carried out after the one-sided adjustment principle of a swing arm. The nip 4 will thereby by the one-sided hydraulic adjustment of one group 6 changed while the other group 7 is tilted slightly. The The size of the angle of attack α allows the adjustment in the specified Size range from 5 or 10 mm.

Das Verstellen um die gesamte Verstellweglänge hingegen erfolgt mit dem in den Fig. 4 und 5 dargestellten Verstellwerkzeug. Das Verstellwerkzeug weist vier Verstellorgane 13 auf, mit denen es auf die Vierkantprofile an den oberen Enden 10 der Verbindungselemente 8 aufgesetzt werden kann. Die Verstellorgane 13 weisen Schneckengetriebe 14 auf, mittels derer sie über die gemeinsame Welle 15 und die Stirnradgetriebe 16 von einem Elektromotor 17 angetrieben werden. Wie insbesondere aus Fig. 5 ersichtlich ist, sind die Verstellorgane 13 durch die Welle 15 und die Stirnradgetriebe 16 starr miteinander gekuppelt. Ferner erfolgt der Antrieb der Verstellorgane 13 durch den allen Verstellorganen 13 gemeinsamen Antrieb 17. Somit erfolgt zwangsweise eine synchrone Verstellung der Verbindungselemente 8.On the other hand, the adjustment by the entire adjustment path length is carried out with the adjustment tool shown in FIGS. 4 and 5. The adjustment tool has four adjusting elements 13 with which it the square profiles at the upper ends 10 of the connecting elements 8 can be put on. The adjusting members 13 have worm gears 14, by means of which they on the common shaft 15 and the spur gear 16 is driven by an electric motor 17 become. As can be seen in particular from FIG. 5, the Adjustment elements 13 through the shaft 15 and the spur gear 16 rigidly coupled together. Furthermore, the adjustment elements are driven 13 through the common of all adjusting elements 13 Drive 17. This means that synchronous adjustment is mandatory the connecting elements 8.

Das Aufsetzen des Verstellwerkzeugs auf das Walzgerüst erfolgt dadurch, daß das Verstellwerkzeug mittels eines nicht dargestellten Krans an einer Öse 18 gehalten und auf das Walzgerüst abgesenkt wird. Mittels eines Handgriffs 19 kann dabei eine Justierung des Verstellwerkzeugs beim Absenken auf das Walzgerüst erfolgt.The adjustment tool is placed on the roll stand characterized in that the adjusting tool by means of a not shown Crane held on an eyelet 18 and lowered onto the roll stand becomes. An adjustment of the Adjusting tool is carried out when lowering onto the roll stand.

Das Aufsetzen des Verstellwerkzeugs auf das Walzgerüst ist selbstverständlich unabhängig vom Ort des Walzgerüsts. Das Walzgerüst kann sich also wahlweise in der Walzstraße oder außerhalb dieser Walzstraße, z.B. in einem Umrüstbereich, befinden. It goes without saying that the adjustment tool is placed on the roll stand regardless of the location of the roll stand. The roll stand can so either in the rolling mill or outside this rolling mill, e.g. in a conversion area.

Alternativ kann auch das Verstellwerkzeug stationär ausgebildet sein. In diesem Fall wird das Walzgerüst - z.B. mittels eines Krans - auf das Verstellwerkzeug aufgesetzt.Alternatively, the adjustment tool can be made stationary be. In this case the roll stand - e.g. by means of a crane - placed on the adjustment tool.

Obenstehend wurde das Verstellen des Walzgerüsts bezüglich seiner horizontal angeordneten Walzen 1 beschrieben. Das Walzgerüst gemäß Ausführungsbeispiel weist aber auch zwei Walzen 1' mit vertikalen Walzenachsen 2' auf. Der Ausbau, die Lagerung, die Verstellung (auch unter Last) usw. erfolgen dabei völlig analog. Korrespondierende Elemente bezüglich der Walzen 1' weisen daher die gleiche Nummer auf wie die entsprechenden Elementen bei den Walzen 1. Die Bezugszeichen sind lediglich zur Unterscheidung mit einem Strich versehen. Der einzige erwähnenswerte Unterschied besteht darin, daß pro Gruppe 6', 7' von Verbindungselementen 8' nur je ein Verbindungselement 8' vorhanden ist. Die Verstellrichtung dieser Walzen 1' ist in den Figuren 2 und 3 mit y bezeichnet. Above was the adjustment of the roll stand with respect to it horizontally arranged rollers 1 described. The roll stand according to Embodiment also has two rollers 1 'with vertical Roll axes 2 '. The expansion, the storage, the adjustment (also under load) etc. are completely analog. Corresponding Elements relating to the rollers 1 'therefore have the same number on how the corresponding elements in the rollers 1. The reference numerals are only marked with a line to distinguish them. The only difference worth mentioning is that per group 6 ', 7' of connecting elements 8 'only one connecting element each 8 'is present. The direction of adjustment of these rollers 1 'is in the Figures 2 and 3 designated y.
