Description

Die Erfindung betrifft eine Profilwalzvorrichtung für Bänder, Platten und dgl. flache Werkstoffbahnen, bei der in einem Walzgerüst in ihren Wirkstellungen arretierbare, als Drehscheiben ausgebildete obere und untere, mit mehreren austauschbaren Profilwalzen versehene Walzenwechselvorrichtungen angeordnet sind, bei denen von jeder Drehscheibe wenigstens eine Profilwalze angetrieben und mit einer Gegen-Profilwalze im Eingriff ist.The invention relates to a profile rolling device for strips, plates and the like.Flat material webs, in which in a rolling stand in their operative positions lockable, designed as turntables upper and lower, provided with several interchangeable profile rollers are arranged, in which at least one profile roller is driven by each turntable and is engaged with a counter-profile roller.

Derartige Walzgerüste sind bekannt, beispielsweise aus der DE 25 56 974 C3, aus der DE 28 16 993 C2 oder aus der EP 0 457 556 A1.Roll stands of this type are known, for example from DE 25 56 974 C3, from DE 28 16 993 C2 or from EP 0 457 556 A1.

Bei den bekannten Profilwalzvorrichtungen sind die oberen und die unteren, in ihrer Winkelstellung arretierbaren Drehscheiben mit zusammenwirkenden Ober- und Unterwalzen ausgerüstet, von denen jeweils eine Ober- und Unterwalze im Eingriff miteinander sind, und bei denen die oberen und die unteren Drehscheiben zusammenpassende Profilwalzenpaare aufweisen, die wahl- und paarweise in Einsatz gebracht werden können. Die in den in der senkrechten Walzwerksebene verstell- und arretierbaren Drehscheiben gelagerten Profilwalzenpaare sind auswechselbar, so dass sehr unterschiedliche Profile gewalzt werden können. Ferner ist es beim Stand der Technik auch möglich, die Drehscheiben mit ihren Profilwalzensätzen als Ganzes auszutauschen.In the known profile rolling devices, the upper and lower turntables, which can be locked in their angular position, are equipped with interacting upper and lower rollers, of which one upper and lower roller are in engagement with each other, and in which the upper and lower turntables have matching profile roller pairs, that can be used in pairs or in pairs. The pairs of profile rollers, which are mounted in the turntables that can be adjusted and locked in the vertical rolling mill plane, are interchangeable, so that very different profiles can be rolled. Furthermore, it is also possible in the prior art to replace the turntables with their profile roller sets as a whole.

Der Antrieb der sich in ihrer Wirkposition befindenden Profilwalzen erfolgt bei den bekannten Profilwalzvorrichtungen beispielsweise dadurch, dass jede der Profilwalzen wenigstens auf einer Gerüst-Seite mit einem ausserhalb des Walzgerüstes fliegend angeordneten Zahnritzel versehen ist, und dass jedes der Zahnritzel der beiden paarweise im Eingriff befindlichen Profilwalzen jeweils ein ortsfest im Gerüst gelagertes Zahnritzel kämmt. Diese beiden ortsfest gelagerten Zahnritzel sind nach der DE 25 56 974 C3 mit einer Doppelkette verbunden, nach der DE 28 16 993 C2 von Elektromotoren einzeln angetrieben.In the known profile rolling devices, the profile rollers in their active position are driven, for example, by the fact that each of the profile rollers is provided with a toothed pinion that is arranged to fly outside the roller stand, at least on one side of the stand, and that each of the toothed pinions of the two profile rollers engaged in pairs each combs a toothed pinion mounted in a fixed position in the frame. These two stationary sprockets are connected according to DE 25 56 974 C3 with a double chain, individually driven by electric motors according to DE 28 16 993 C2.

Die Ausbildungsweisen nach diesem Stand der Technik können höheren beiriebswirtschaftlichen Fertigungsansprüchen nicht genügen. Die zu formenden Bänder oder Blechabschnitte sind sehr oberflächenempfindlich, denn sie sind entweder - vor allem Aluminium-Werkstoffe - blankgewalzt, eloxiert oder bandbeschichtet, oder in anderer Weise oberflächenbehandelt; z. B. können Stahlwerkstoffe galvanisch oder feuerverzinkt oder kunststoffbeschichtet sein, bevor sie verformt werden. Bein Verformungsprozess dürfen die empfindlichen Oberflächen nicht durch Kratz- oder Schleifspuren in ihrer Güte und ihrem Aussehen beeinträchtigt werden.The training methods according to this state of the art cannot meet higher commercial production requirements. The strips or sheet metal sections to be formed are very sensitive to the surface because they are either - primarily aluminum materials - bright rolled, anodized or coil coated, or they are surface-treated in some other way; e.g. B. steel materials can be galvanized or hot-dip galvanized or plastic-coated before they are deformed. During the deformation process, the sensitive surfaces must not be impaired in their quality and appearance by scratching or grinding marks.

Ein ausreichend oberflächenschonendes Rollenverformen setzt nicht nur einwandfrei glatte, hochglanzpolierte Profilwalzen voraus, sondern vor allem eine der Vorschubgeschwindigkeit genau entsprechende Umfangsgeschwindigkeit der im Eingriff befindlichen Rollenpaare. Schon geringfügigste Unterschiede der Umfangsgeschwindigkeiten können zu Schleifspuren auf den feinen Oberflächen führen. Vor allem muss sichergestellt sein, dass bei den beiden im Eingriff befindlichen Profilwalzen die Drehzahlen übereinstimmen. Bei dem im Stand der Technik vorgeschlagenen Kettenantrieb ist dies nicht gewährleistet, weil ein doppeltes Zahnspiel und auch Ketten-Ungleichförmigkeiten zu Drehwinkelverschiebungen der Profilwalzen führen. Auch der motorische Einzelantrieb der Profilwalzen vermag nicht sicherzustellen, dass diese absolut drehwinkelsynchron angetrieben werden.A sufficiently surface-protecting roll forming not only requires perfectly smooth, highly polished profile rolls, but above all a circumferential speed of the engaged pairs of rollers that corresponds exactly to the feed speed. Even the slightest difference in circumferential speeds can lead to grinding marks on the fine surfaces. Above all, it must be ensured that the the two engaged profile rollers match the speeds. In the chain drive proposed in the prior art, this is not guaranteed because a double tooth play and also chain irregularities lead to angular displacements of the profile rollers. Even the motorized individual drive of the profile rollers cannot ensure that they are driven absolutely synchronously with the rotation angle.

Nachteilig ist ferner, dass beim Wechsel des herzustellenden Profils eine komplizierte und zeitaufwendige Profilwalzen-Umsetzarbeit erforderlich ist. Der Kettenantrieb muss zunächst entfernt werden, damit das Umstellen der Drehscheiben erfolgen kann; danach muss der Kettenantrieb wieder hergestellt werden. Ausserdem kommt es darauf an, ob der neue Profilwalzensatz andere Walzendurchmesser aufweist, so dass unter Umständen die Kettenräder gewechselt werden müssen.Another disadvantage is that when the profile to be produced is changed, complicated and time-consuming profile roller conversion work is required. The chain drive must first be removed so that the turntables can be moved; then the chain drive must be restored. It also depends on whether the new profile roller set has a different roller diameter, so that the chain wheels may have to be replaced.

In der Schrift EP 0 457 556 A1 ist vorgeschlagen worden, dass das Antreibsdrehmoment über ein im Gestell ortsfest angeordnetes Antriebszahnrad auf ein Zahnritzel, das mit einer der sich in Wirkposition befindenden Profilwalzen verbunden ist, und von diesem über ein zweites mit dieser Profilwalze verbundenen Zahnritzel auf ein drittes Zahnritzel übertragen wird, welches mit der gegenüberliegenden, sich in ihrer Wirkposition befindenden Profilwalze verbunden ist. Dabei werden die Profilwalzen, die sich nicht in ihrer Wirkposition befinden, sowie ihre Zahnritzel nicht mitaugetrieben.In document EP 0 457 556 A1 it has been proposed that the driving torque be applied to a pinion, which is connected to one of the profile rollers in the active position, and from there via a second pinion connected to this profile roller via a drive gear arranged in a fixed position in the frame a third pinion is transmitted, which is connected to the opposite profile roller, which is in its operative position. The profile rollers, which are not in their active position, and their pinions are not driven.

Nachteilig ist bei diesem Stand der Technik der erhebliche konstruktive Aufwand des Profilwalzenantriebs, sowie dass es nicht möglich ist, in ein und derselben Walzenwechselvorrichting Profilwalzen mit unterschiedlichen Durchmessern anzuordnen. Eine Veränderung des Walzspaltes durch Verschieben der Walzenwechselvorrichtungen in der senkrechten Walzwerksebene ist durch die beschriebene Ausbildung des Profilwalzenantriebs ohne Verlust des Kraftschlusses zwischen den Zahnrädern und Zahnritzeln ebenfalls unmöglich.A disadvantage of this prior art is the considerable design effort of the profile roller drive, and that it is not possible to arrange profile rollers with different diameters in one and the same roller changing device. A change in the roll gap by moving the roll changing devices in the vertical rolling mill plane is also impossible due to the described design of the profile roller drive without loss of the frictional connection between the gears and pinions.

Alle Profilwalzvorrichtungen nach dem Stand der Technik haben gemeinsam, dass jeweils nur die in ihrer Wirkstellung befindlichen Profilwalenpaare angetrieben werden; die anderen Profilwalzen in den Walzenwechselvorrichtungen bleiben frei.All profile rolling devices according to the prior art have in common that only the profile roller pairs located in their active position are driven; the other profile rollers in the roller changing devices remain free.

Allgemein wird die Einsatzzeit von bekannten Profilwalzvorrichtungen noch dadurch verringert, dass die Walzen zwischen einer Zahl von Walzungen gereinigt werden müssen: Die unvermeidlicherweise auf den Walzenoberflächen anhaftenden kleinen Schmutzpartikel, sowie der eventuell vorhandene Abrieb, müssen regelmässig entfernt werden, um ein einwandfreies Oberflächenbild des Walzgutes zu erhalten. Diese in kürzeren Zeitabständen notwendige Reinigung der Profilwalzen erfordert jeweils eine längere Stillstandsdauer.In general, the operating time of known profile rolling devices is further reduced by the fact that the rolls have to be cleaned between a number of rolls: the small dirt particles that inevitably adhere to the roll surfaces, as well as any abrasion that may be present, must be removed regularly in order to ensure a perfect surface appearance of the rolling stock receive. This cleaning of the profile rollers, which is necessary at shorter intervals, requires a longer downtime.

Eine Fehlfunktion oder eine Störung bei mehreren, zu einer Walzstrasse hintereinander angeordneten Profilwalzvorrichtungen kann zur Folge haben, dass sich zwei oder mehr Werkstoffbahnen übereinanderschieben, was bei Vorrichtungen nach dem Stand der Technik unweigerlich schwere Lagerschäden nach sich zieht.A malfunction or a fault in a plurality of profile rolling devices arranged one behind the other to form a rolling train can result in two or more material webs sliding over one another, which inevitably results in severe bearing damage in devices according to the prior art.

Die Profilwalzvorrichtungen nach dem Stand der Technik sind daher in mehrfacher Hinsicht verbesserungsbedürftig: Um eine bessere Oberflächengüte des Walzgutes zu erzielen, um ein höheres Ausbringen pro Zeiteinheit zu erreichen, insbesondere durch Verkürzung der zu langen Stillstandszeiten, die teils durch Walzenreinigen, teils durch Umstellen des Walzprogramms auf andere Profile durch Auswechseln der Profilwalzensätze verursacht werden, um die Drehscheiben mit Profilwalzen unterschiedlichen Durchmessers ausrüsten zu können und um die schweren Schäden durch ein unvorhergesehenes Übereinanderschieben von Werkstoffbahnen während des Walzprozesses zu vermindern.The profile rolling devices according to the prior art are therefore in need of improvement in several respects: In order to achieve a better surface quality of the rolling stock, in order to achieve a higher output per unit of time, in particular by shortening the downtimes which are too long, partly due to roller cleaning and partly by changing the rolling program to other profiles caused by changing the profile roller sets in order to be able to equip the turntables with profile rollers of different diameters and to reduce the serious damage caused by an unforeseen sliding of material webs during the rolling process.

Zur Behebung dieser Mängel wird daher erfindungsgemäss bei einer gattungsgemässen Profilwalzvorrichtung vorgeschlagen, dass mit jeder der in Arbeitspostion befindlichen Profilwalze je ein Zahnkranz in Verbindung gebracht, und wenigstens ein in der Mittelachse einer der Drehscheiben gelagertes, das Drehmoment auf die Zahnkränze der Profilwalzen übertragendes Antriebszahnrad angeordnet wird.To remedy these shortcomings, it is therefore proposed according to the invention in a generic profile rolling device that a toothed ring is brought into connection with each of the profile rollers in the working position, and at least one drive gearwheel mounted in the central axis of one of the turntables and transmitting the torque to the ring gear of the profile rollers is arranged .

In einer bevorzugten Ausbildung der erfindungsgemässen Profilwalzvorrichtung werden die als Drehscheiben ausgebildeten Walzenwechselvorrichtungen in ihrer Winkelstellung so arretiert, dass die Verbindungsstrecke zwischen den Mittelachsen der Drehscheiben und den in ihrer Wirkposition befindlichen Profilwalzen jeweils in einem Winkel α zu der die Mittelachsen der Drehscheiben schneidenden Geraden stehen.In a preferred embodiment of the profile rolling device according to the invention, the roller changing devices designed as turntables are locked in their angular position in such a way that the connecting path between the central axes of the turntables and the profile rollers in their active position are each at an angle α to the straight line intersecting the central axes of the turntables.

Zweckmässigerweise erfolgt die Arretierung der Drehscheiben mittels Index-Bolzen, vorzugsweise derart, dass die Index-Bolzen als Sollbruchstellen ausgebildet sind.The turntables are expediently locked by means of index bolts, preferably in such a way that the index bolts are designed as predetermined breaking points.

Durch eine solche erfindungsgemässe Anordnung der Walzenwechselvorrichtungen können die Profilwalzen und die zugehörigen Drehscheiben in der Bewegungsrichtung der Werkstoffbahnen nachgeben, falls durch eine - im allgemeinen nicht selten vorkommende - Störung oder Fehlfunktion ein zerstörtes oder mehrere übereinandergeschobene Werkstücke zwischen die im Eingriff befindlichen Profilwalzen geraten, und infolgedessen sehr hohe, in Bewegungsrichtung wirkende Kräfte auftreten. Somit wird schweren Lagerschäden und den damit verbundenen Stillstandszeiten der Profilwalzvorrichtung vorgebeugt.With such an arrangement of the roll changing devices according to the invention, the profile rolls and the associated turntables can yield in the direction of movement of the material webs if a - or not infrequently occurring - malfunction or malfunction causes a destroyed or several pushed workpieces between the profile rolls in engagement, and as a result very high, in the direction of movement acting forces occur. This prevents severe bearing damage and the associated downtimes of the profile rolling device.

Für ein koordiniertes Verdrehen der Walzenwechselvorrichtungen ist es vorteilhaft, wenn die Drehscheiben mit auf ihren Wellenzapfen sitzenden Antriebsrädern durch ein formschlüssig wirkendes Zugmittel verbunden sind. Dieses Zugmittel kann als EndlosRollenkette oder als Zahnreimen ausgebildet sein. Dadurch können die im Eingriff befindlichen Profilwalzen ohne separates Nachjustieren der Drehscheiben in einem Arbeitsgang gewechselt werden. Bei zu einer Walzstrasse hintereinander angeordneten Profilwalzvorrichtungen können alle Drehscheiben mit einem formschlüssig wirkenden Zugmittel verbunden sein, sodass alle Drehscheiben koordiniert gedreht werden können.For a coordinated rotation of the roller changing devices, it is advantageous if the turntables are connected to drive wheels seated on their shaft journals by means of a traction means that acts in a positive manner. This traction device can be designed as an endless roller chain or as a tooth rhyme. This means that the profile rollers in engagement can be changed in one operation without having to readjust the turntables. In the case of profile rolling devices arranged one behind the other to form a rolling train, all turntables can be connected to a form-fitting traction means, so that all turntables can be rotated in a coordinated manner.

In einer bevorzugten Ausbildung einer Profilwalzvorrichtung nach der Erfindung ist vorgesehen, dass den Profilwalzen Reinigungswalzen zugeordnet sind, die ebenfalls in den Drehscheiben gelagest sind, und die in ihrer Wirkstellung unter leichtem Anpressdruck an die Profilwalzen stehen. Durch Reibschluss mit den Profilwalzen werden die Reinigungswalzen mitgedreht. Erfindungsgemäss können alle Profilwalzen, auch die, die sich nicht in ihrer Wirkstellung befinden, mitangetrieben werden, sodass bei allen Profilwalzen eine kontinuierliche Reinigung durch die Reinigungswalzen gewährleistet ist.In a preferred embodiment of a profile rolling device according to the invention, it is provided that the profile rollers are assigned cleaning rollers which are also located in the turntables and which are in their operative position under a slight contact pressure on the profile rollers. The cleaning rollers are rotated by frictional engagement with the profile rollers. According to the invention, all profile rollers, even those that are not in their active position, can also be driven, so that continuous cleaning by the cleaning rollers is ensured for all profile rollers.

Durch solche erfindungsgemässen Reinigungswalzen werden weitere Stillstandszeiten der Profilwalzvorrichtung vermieden. Reschädigungen der Werkstoffoberflächen durch zu lange Reinigungsintervalle werden dadurch ebenfalls verhindert.Such downtimes of the profile rolling device are avoided by such cleaning rollers according to the invention. This also prevents damage to the material surfaces due to cleaning intervals that are too long.

Damit für die Unterbringung der Reinigungswalzen genügend Raum verbleibt, ist es zweckmässig, dass in den Drehscheiben höchstens je drei austauschbare Profilwalzen angeordnet sind.So that there is enough space to accommodate the cleaning rollers, it is expedient for a maximum of three interchangeable profile rollers to be arranged in the turntables.

Vorteilhafterweise sind die Reinigungswalzen entsprechend ihren zugehörigen Profilwalzen profiliert und zumindest in den in Profilvertiefungen der Profilrollen eingreifenden Umfangsbereichen mit einer elastischen und zugleich porösen, zur Aufnahme eines Reinigungsmittels oder von Walzenschmieröl vorgesehenen Beschichtung versehen. Dadurch wird vor allem in den Profilvertiefungen der Profilrollen, in denen sich die Schmutzpartikel bevorzugt sammeln, eine gute Reinigungswirkung erzielt.The cleaning rollers are advantageously profiled in accordance with their associated profile rollers and are provided, at least in the circumferential regions engaging in profile recesses of the profile rollers, with an elastic and at the same time porous coating intended to hold a cleaning agent or roller lubricating oil. As a result, a good cleaning effect is achieved especially in the profile recesses of the profile rollers, in which the dirt particles preferentially collect.

Zum leichteren Austausch der Reinigungswalzen ist weiterhin vorgesehen, diese beidseitig an in den Drehscheiben schwenkbar angeordneten Lenkern zu lagern, wodurch sie aus ihrer arretierbaren Wirkstellung in eine von den Profilwalzen beabstandete Bereitschaftsstellung schwenkbar sind.To make it easier to replace the cleaning rollers, provision is further made to mount them on both sides on links pivotably arranged in the turntables, as a result of which they can be pivoted out of their lockable operative position into a standby position spaced apart from the profile rollers.

Zweckmässigerweise sind die Profilwalzen und die Reinigungswalzen in den Drehscheiben mit ihren Lagerschalen in Gabel-Lagersitzen nachstellbar und ausrichtbar befestigt.The profile rollers and the cleaning rollers in the turntables are expediently fastened with their bearing shells in fork bearing seats so that they can be adjusted and aligned.

Eine vorteilhafte Ausbildung der Profilwalzvorrichtung nach der Erfindung besteht darin, dass mindestens eine der Drehscheiben an den Walzgerüsten mittels höhenverstellbarer und in ihren Wirkstellungen arretierbarer Führungsschlitten zueinander abstandsveränderlich einstellbar sind. Dadurch kann der Walzspalt für verschiedene Dicken der Werkstoffbahnen verändert werden. Auch ein Wechsel auf Profilwalzen mit einem anderen Durchmesser wird so möglich.An advantageous embodiment of the profile rolling device according to the invention consists in that at least one of the turntables on the rolling stands can be adjusted in relation to one another by means of height-adjustable guide carriages which can be locked in their operative positions. As a result, the roll gap can be changed for different thicknesses of the material webs. It is also possible to change to profile rollers with a different diameter.

Für die schnellere Anpassung der Profilwalzvorrichtung an verschiedene Walzprofile wird erfindungsgemäss weiterhin vorgeschlagen, dass die Walzenwechselvorrichtungen mit den Profilwalzen und den Reinigungswalzen als Ganzes austauschbar sind.For faster adaptation of the profile rolling device to different rolled profiles, it is further proposed according to the invention that the roller changing devices can be exchanged as a whole with the profile rollers and the cleaning rollers.

Zweckmässigerweise sind die beidseitigen Drehscheiben mitsamt ihren Profil- und Reinigungswalzensätzen mit ihren Lagerschalen in Gabel-Lagersitzen der Lagerschilder nachstellbar befestigt.The turntables on both sides together with their profile and cleaning roller sets are expediently fastened with their bearing shells in fork-bearing seats of the end shields.

Für die Gewährleistung einer identischen Umfangsgeschwindigkeit der sich im Eingriff miteinander befindenden Profilwalzen ist erfindungsgemäss vorgesehen, dass die beiden gegenüberliegenden Profilwalzen gleiche effektive Profilwalzenradien aufweisen. Der effektive Profilwalzenradius wird dabei durch den kürzesten Abstand zwischen der geometrischen Profilwalzen-Achse und der neutralen Walzebene definiert.In order to ensure an identical peripheral speed of the profile rollers which are in engagement with one another, the invention provides that the two opposite profile rollers have the same effective profile roller radii. The effective roll radius is defined by the shortest distance between the geometrical roll axis and the neutral roll plane.

Nach einer weiteren Ausbildung der erfindungsgemässen Profilwalzvorrichtung sind die Profilwalzen in den als Drehscheiben ausgebildeten Walzenwechselvorrichtungen auf verschiedenen Teilkreisen mit unterschiedlichen Radien angeordnet. Somit können auch Profilwalzen mit unterschiedlichen Durchmessern in ein und derselben Walzenwechselvorrichtung enthalten sein, ohne den Kraftschluss des Profilwalzenantriebs zu verlieren.According to a further embodiment of the profile rolling device according to the invention, the profile rolls are arranged in the roller changing devices designed as turntables on different pitch circles with different radii. Thus, profile rollers with different diameters can also be contained in one and the same roller changing device without losing the frictional connection of the profile roller drive.

Weiterhin ist zur kontinuierlichen Formung der Werkstoffbahnen erfindungsgemäss vorgesehen, dass eine Mehrzahl von Walzgerüsten in Reihe hintereinander angeordnet und deren Antriebszahnräder mit motorischen Einzelantrieben mittels lösbarer homokinetisch wirkender Schnellkupplungen verbunden sind, und bei der die Einzelantriebe der einzelnen Walzenpaare in Abhängigkeit von den effektiven Profilwalzenradien der im Eingriff befindlichen Walzenpaare mit jeweils rechnerisch ermittelten Werten drehzahlgesteuert sind.Furthermore, according to the invention, for the continuous shaping of the material webs, it is provided that a plurality of roll stands are arranged in series one behind the other and their drive gearwheels are connected to individual motor drives by means of releasable homokinetically acting quick-action couplings, and in which the individual drives of the individual roll pairs are in engagement depending on the effective profile roll radii located roller pairs are speed-controlled, each with arithmetically determined values.

Die folgenden Ausführungsbeispiele der Erfindung lassen weitere vorteilhafte Merkmale und Besonderheiten erkennen, die anhand der Darstellungen näher beschrieben sind.The following exemplary embodiments of the invention reveal further advantageous features and special features which are described in more detail with reference to the illustrations.

In Figur 1 liegen je drei Profilwalzen-Achsen 20 auf einem Kreis 10 um die Mittelachsen 19 der Drehscheiben 18, wobei auf jeder Profilwalzen-Achse 20 ein Zahnkranz 22 befestigt ist. Die Zahnkränze 22 der Profilwalzen der unteren Drehscheibe 18 sind mit einem auf deren Mittelachse 19 angebrachten Antriebszahnrad 23 im Eingriff, von dem sie angetrieben werden. Das Drehmoment des Antriebszahnrads 23 wird über den Zahnkranz 22 der an die neutrale Walzebene E heranreichenden Profilwalze auf den Zahnkranz 22 der gegenüberliegenden Profilwalze übertragen, wodurch beide im Eingriff befindlichen Profilwalzen eine auf den effektiven Profilwalzenradius R bezogene, identische Umfangsgeschwindigkeit bei jeweils gleichbleibendem Drehwinkel erhalten. Der effektive Profilwalzenradius R ist dabei durch den kürzesten Abstand zwischen den Profilwalzen-Achsen 20 und der neutralen Walzebene E gegeben. Durch die Drehung der Profilwalzen 21 wird ein nicht dargestelltes Werkstück in der neutralen Walzebene E vorwärtsgetrieben.In FIG. 1, three profile roller axes 20 each lie on a circle 10 around the central axes 19 of the turntables 18, a toothed ring 22 being fastened on each profile roller axis 20. The ring gears 22 of the profile rollers of the lower turntable 18 are provided with a drive gear 23 attached to the central axis 19 thereof engaged by which they are driven. The torque of the drive gear 23 is transmitted via the ring gear 22 of the profile roller approaching the neutral roller plane E to the ring gear 22 of the opposite profile roller, whereby both profile rollers in engagement receive an identical circumferential speed, based on the effective profile roller radius R, with the rotation angle remaining constant. The effective profile roller radius R is given by the shortest distance between the profile roller axes 20 and the neutral roller plane E. The rotation of the profile rollers 21 drives a workpiece (not shown) in the neutral roller plane E.

In Figur 2 ist zusätzlich zur Figur 1 ein als Zahnriemen ausgebildetes, formschlüssiges Zugmittel 13 dargestellt, das über die an den Mittelachsen 19 der Drehscheiben 18 angebrachten Antriebsräder 14 eine koordinierte Verdrehung der Drehscheiben 18 zum Zweck des Wechsels der Profilwalzen 21 ermöglicht. Die Mittelachse 15 der Antriebsräder 14 liegt dabei genau auf der Mittelachse 19 der Drehscheiben 18.In FIG. 2, in addition to FIG. 1, a positive-locking traction means 13 designed as a toothed belt is shown, which, via the drive wheels 14 attached to the central axes 19 of the turntables 18, enables a coordinated rotation of the turntables 18 for the purpose of changing the profile rollers 21. The central axis 15 of the drive wheels 14 lies exactly on the central axis 19 of the turntables 18.

In Figur 3 sind jeweils drei Profilwalzen 21 unterschiedlichen Durchmessers in den Drehscheiben 18 gelagert, wobei die zugehörigen Antriebszahnräder und Zahnkränze nicht dargestellt sind. Jeder Profilwalze 21 ist je eine Reinigungswalze 24 zugeordnet, die, aufgrund ihrer Lagerung im schwenkbaren Lenker 27, aus ihrer Wirkstellung W, in der sie reibschlüssig mit der Profilwalze 21 mitangetrieben wird, in eine Bereitschaftsstellung B geschwenkt werden kann. Die Drehscheiben 18 sind dabei in einem auf einem Grundrahmen 6 aufgestellten Walzgerüst 4 vertikal versehiebbar gelagert.In Figure 3, three profile rollers 21 of different diameters are each mounted in the turntables 18, the associated drive gears and ring gears not being shown. Each profile roller 21 is assigned a cleaning roller 24, which, due to its mounting in the pivotable handlebar 27, can be pivoted from its operative position W, in which it is frictionally driven with the profile roller 21, into a standby position B. The turntables 18 are mounted vertically displaceably in a roll stand 4 set up on a base frame 6.

Figur 4 verdeutlicht die Verdrehung der Verbindungsstrecken zwischen den Profilwalzen-Achsen 20 der im Eingriff befindlichen Profilwalzen 21 und ihrer Zahnkränze einerseits, und den Mittelachsen 19 der Drehscheiben andererseits, gegenüber der beide Mittelachsen 19 der Drehscheiben schneidenden Geraden G um jeweils den Winkel α.Figure 4 illustrates the rotation of the connecting paths between the profile roller axes 20 of the engaged profile rollers 21 and their sprockets on the one hand, and the central axes 19 of the turntables on the other hand, relative to the straight line G intersecting both central axes 19 of the turntables by the angle α.

Das Walzgerüst in Figur 5 wird durch einen Grundrahmen 6 und Walzgerüstsäulen 8 gebildet. Die Drehscheiben 18 mit den in Lagerschalen 30 eingesetzten Profilwalzen 21 sind mit Lagerschalen 32 in Lagerschilden 7 von Führungsschlitten 9 gelagert, welche auf den Walzgerüstsäulen 8 zur Anpassung an verschiedene Walzendurchmesser und Werkstückdicken verschiebbar angebracht sind. Die mit dem formschlüssigen Zugmittel 13 und den dazugehörigen Antriebsrädern 14 zum Walzenwechsel koordiniert verdrehbaren Drehscheiben 18 werden durch Index-Bolzen 17 in ihren Wirkstellungen festgehalten. Das Drehmoment, das auf die Antriebswelle 28 wirkt, wird über das auf der Mittelachse 19 der unteren Drehscheibe 18 befindliche, zentrale Antriebszahnrad 23 und die auf den Profilwalzen-Achsen 20 sitzenden Zahnkränze 22 auf die Profilwalzen 21, und damit letztlich auf das Werkstück übertragen.The roll stand in FIG. 5 is formed by a base frame 6 and roll stand columns 8. The turntables 18 with the profile rollers 21 inserted in the bearing shells 30 are mounted with bearing shells 32 in bearing plates 7 of guide carriages 9, which are slidably mounted on the roll stand columns 8 to adapt to different roller diameters and workpiece thicknesses. The rotating disks 18 coordinated with the positive traction means 13 and the associated drive wheels 14 for changing the rollers are held in their operative positions by index bolts 17. The torque that acts on the drive shaft 28 is transmitted to the profile rollers 21, and thus ultimately to the workpiece, via the central drive gear 23 located on the central axis 19 of the lower turntable 18 and the toothed rings 22 seated on the profile roller axes 20.

In Figur 6 ist ein Walzstrassenabschnitt, bestehend aus zwei Profilwalzmaschinen, dargestellt. Die Walzgerüste 4 werden hier, wie in Figur 5, durch einen Grundrahmen 6 und Walzgerüstsäulen 8 gebildet. Die Walzenwechselvorrichtungen 11 sitzen in den Lagerschilden 7 von Führungsschlitten 9, welche mittels Anstellspindeln 5 auf den Walzgerüstsäulen 8 für die Anpassung an verschiedene Walzendurchmesser und verschiedene Werkstückdicken vertikal verstellbar befestigt sind. Die Walzenwechselvorrichtungen 11 bestehen, wie in den vorhergehenden Abbildungen, aus Drehscheiben 18, die in ihren Mittelachsen 19 drehbar gelagert sind, und in denen sich jeweils drei Profilwalzen 21 befinden.FIG. 6 shows a rolling mill section consisting of two profile rolling machines. The roll stands 4 are formed here, as in FIG. 5, by a base frame 6 and roll stand columns 8. The roll changing devices 11 are seated in the end shields 7 of guide carriages 9, which are fastened in a vertically adjustable manner by means of adjusting spindles 5 on the roll stand columns 8 for adaptation to different roll diameters and different workpiece thicknesses. The roller changing devices 11 consist, as in the previous figures, of turntables 18 which are rotatably mounted in their central axes 19 and in which there are three profile rollers 21 in each case.

Figur 7 zeigt einen Teil zweier im Eingriff befindlicher Profilwalzen 21 mit dem zwischen ihnen liegenden, zu formenden Werkstück. Es wird deutlich, dass die neutrale Walzebene F nicht die Null-Linie des Werkstücks in seiner ebenen Ausgangsform ist, sondern in der Mitte zwischen der grössten Vertiefung, bzw. Erhöhung und der Null-Linie der im Eingriff befindlichen Profilwalzen 21 liegt.

Figure imgb0001
FIG. 7 shows a part of two profile rollers 21 in engagement with the workpiece to be formed between them. It is clear that the neutral roller plane F is not the zero line of the workpiece in its flat initial shape, but lies in the middle between the largest depression or elevation and the zero line of the profile rollers 21 in engagement.
