Description

Die Erfindung betrifft eine Walzvorrichtung zum dornlosen Walzen von Rädern und Scheiben, mit einem Walzengestell, in das ein kreisscheibenförmiger Rohling um eine Drehachse drehbar einsetzbar ist, einer Hauptwalze, die um eine parallel zur Drehachse verlaufende Achse drehbar und mit der Umfangsfläche des Rohlings in Anlage bringbar ist, und zumindest einem Paar von Kegelwalzen und zumindest einem Paar von Stegwalzen, die jeweils mit den Seitenflächen des Rohlings in Anlage bringbar sind, wobei die Stegwalzen mittels einer Antriebsvorrichtung drehangetrieben sind.The invention relates to a rolling apparatus for the thornless rolling of wheels and discs, with a roller frame, in which a circular disk-shaped blank is rotatably insertable about a rotation axis, a main roller which is rotatable about an axis parallel to the axis of rotation and engageable with the peripheral surface of the blank in abutment is, and at least a pair of tapered rollers and at least a pair of web rolls, which are respectively engageable with the side surfaces of the blank, wherein the web rolls are rotationally driven by means of a drive device.

Ferner betrifft die Erfindung ein Verfahren zum dornlosen Walzen von Rädern und Scheiben mit einer entsprechenden Walzvorrichtung.Furthermore, the invention relates to a method for thornless rolling of wheels and discs with a corresponding rolling device.

Um ein Rad oder eine Scheibe in einer Walzvorrichtung aus einem stählernen, kreisscheibenförmigen Rohling herauszuarbeiten, war es früher bekannt, den Rohling mittig auf einen Dorn aufzusetzen und in Drehung zu versetzen. In der Zwischenzeit ist man jedoch dazu übergegangen, Räder und Scheiben dornlos zu walzen, indem man einen scheibenförmigen Rohling üblicherweise aufrecht stehend in ein Walzengestell einsetzt, in dem der Rohling an seiner Umfangsfläche und seinen Seitenflächen durch Lagerwalzen schwimmend gelagert ist. Zum Walzengestell gehört auch eine sogenannte Hauptwalze, die um eine parallel zur Drehachse des Rohlings verlaufende Achse drehbar ist und mit der Umfangsfläche des Rohlings in Anlage steht und diese während des Walzvorganges ausformt. Ferner sind kegelförmige Walzen, sogenannte Kegelwalzen vorgesehen, die im Randbereich des Rohlings mit dessen Seitenflächen auf entgegengesetzten Seiten in Anlage treten und insbesondere den radial äußeren Radkranz oder Scheibenkranz ausformen. Der zwischen der radial inneren Nabe und dem radial äußeren Radkranz des Rades liegende Stegbereich wird von sogenannten Stegwalzen ausgeformt, die von entgegengesetzten Seiten mit den Seitenfläche des Rohlings in Anlage treten.To work out a wheel or a disk in a rolling apparatus from a steel disc-shaped blank, it was previously known to put the blank centrally on a mandrel and to set in rotation. In the meantime, however, one has gone over to roll wheels and discs thornless, by a disc-shaped Blank usually used upright in a roller frame, in which the blank is mounted floating on its peripheral surface and its side surfaces by bearing rollers. The roller frame also includes a so-called main roller which is rotatable about an axis extending parallel to the axis of rotation of the blank and is in contact with the peripheral surface of the blank and forms it during the rolling process. Furthermore, cone-shaped rollers, so-called tapered rollers are provided, which come into contact in the edge region of the blank with its side surfaces on opposite sides and in particular form the radially outer rim or disc rim. The web region lying between the radially inner hub and the radially outer wheel rim of the wheel is formed by so-called web rolls, which come into contact with the side surface of the blank from opposite sides.

Um den Rohling in dem Walzengestell in Drehung zu versetzen, dienen die drehangetriebenen Stegwalzen. Die Drehbewegung der Stehwalzen wird über Reibung auf den Rohling übertragen, wodurch dieser ebenfalls in Drehung versetzt wird. Aufgrund des Kontaktes mit dem rotierenden Rohling beginnen auch die mit diesem in Anlage stehenden Walzen, d.h. die Hauptwalze und die Kegelwalze zu drehen. Da die Beschleunigung des Rohlings somit allein durch die Reibung zwischen den Stegwalzen und dem Rohling erfolgt, sind die Stegwalzen einen sehr hohem Verschleiß unterworfen. Darüber hinaus kann es aufgrund der relativ großen Masse des Rohlings zu einem unerwünschten Schlupf insbesondere zwischen den Stegwalzen und dem Rohling kommen, was die Bearbeitungsgenauigkeit nachteilig beeinflusst.To rotate the blank in the roll stand, the rotary driven web rolls serve. The rotational movement of the standing rollers is transmitted by friction to the blank, whereby this is also rotated. Due to the contact with the rotating blank, the rolls in contact therewith, ie the main roll and the tapered roll, also begin to rotate. Since the acceleration of the blank thus takes place solely by the friction between the web rolls and the blank, the web rolls are subjected to very high wear. Moreover, due to the relatively large mass of the blank, unwanted slippage may occur, in particular between the web rolls and the blank, which adversely affects the machining accuracy.

Der Erfindung liegt die Aufgabe zugrunde, eine Walzvorrichtung zum dornlosen Walzen von Rädern und Scheiben zu schaffen, bei der die Belastung und der Verschleiß der Stegwalzen reduziert ist.The invention has for its object to provide a rolling device for thornless rolling of wheels and discs, in which the load and wear of the web rolls is reduced.

Darüber hinaus soll ein Verfahren zum dornlosen Walzen von Rädern und Scheiben geschaffen werden, bei dem der Verschleiß der Stegwalzen reduziert ist.In addition, a method for thornless rolling of wheels and discs is to be created, in which the wear of the web rolls is reduced.

Diese Aufgabe wird erfindungsgemäß hinsichtlich der Walzvorrichtung durch die Merkmale des Anspruchs 1 gelöst. Dabei ist vorgesehen, dass die Kegelwalzen und die Hauptwalze ebenfalls jeweils eine Antriebsvorrichtung zum Drehantrieb aufweisen. Auf diese Weise wird die Drehung des Rohlings nicht mehr alleine durch die Stegwalzen erreicht, sondern die Hauptwalze und die Kegelwalzen können ebenfalls dazu herangezogen werden, den Rohling in Drehung zu versetzen. Auf diese Weise ist insbesondere in der Beschleunigungsphase eine verringerte Reibung und ein verminderter Schlupf zwischen den Stegwalzen und dem Rohling gegeben, so dass dessen Verschleiß herabgesetzt ist.This object is achieved with respect to the rolling device by the features of claim 1. It is provided that the tapered rollers and the main roller also each have a drive device for rotary drive. In this way, the rotation of the blank is no longer achieved solely by the web rolls, but the main roll and the tapered rollers can also be used to set the blank in rotation. In this way, especially in the acceleration phase, a reduced friction and a reduced slip between the web rolls and the blank is given, so that its wear is reduced.

Vorzugsweise sind alle Antriebsvorrichtungen, d.h. die Antriebsvorrichtung der Stegwalzen, die Antriebsvorrichtung der Hauptwalze und die Antriebsvorrichtung der Kegelwalzen unabhängig voneinander ansteuerbar. Auf diese Weise kann vorgesehen sein, dass die Antriebsvorrichtung der Hauptwalze und/oder die Antriebsvorrichtung der Kegelwalzen beim Walzvorgang momentenfrei geschaltet werden, wenn es beispielsweise beim Walzen des Rohlings zu keiner Überlagerung von Antriebsmomenten kommen soll. Nachdem die Stegwalzen mit dem Rohling in Anlage getreten sind, kann der Rohling ausschließlich mittels der Stegwalzen in Rotation gehalten werden. Durch Einbringen zusätzlicher Momente mittels der Antriebsvorrichtungen der Hauptwalze und/oder der Kegelwalzen kann es im Walzprozess zu einem erhöhten Verschleiß dieser Walzen kommen. Dies wird verhindert, wenn die Antriebsvorrichtungen der Hauptwalze und/oder der Kegelwalzen so eingestellt werden, dass die Hauptwalze und/oder die Kegelwalzen durch den Rohling angetrieben werden oder dass die Umfangsgeschwindigkeit der Hauptwalze und/oder der Kegelwalzen gleich der Umfangsgeschwindigkeit des Rohlings im Kontaktbereich ist, d.h. zwischen den miteinander in Anlage stehenden Bauteilen an der Kontaktfläche keine Geschwindigkeitsdifferenz gegeben ist.Preferably, all drive devices, ie the drive device of the web rolls, the drive device of the main roll and the drive device of the tapered rollers are independently controllable. In this way it can be provided that the drive device of the main roller and / or the drive device of the tapered rollers are switched during the rolling torque-free, if it should come, for example, when rolling the blank to no superposition of drive torque. After the web rolls have come into contact with the blank, the blank can be kept in rotation exclusively by means of the web rolls become. By introducing additional moments by means of the drive devices of the main roll and / or the tapered rollers, increased wear of these rolls may occur in the rolling process. This is prevented when the driving devices of the main roll and / or the tapered rolls are adjusted so that the main roll and / or the tapered rolls are driven by the blank or the circumferential speed of the main roll and / or the tapered rolls is equal to the peripheral speed of the blank in the contact region ie, there is no speed difference between the abutting components at the contact surface.

Hinsichtlich des Verfahrens wird die oben genannte Ausgabe dadurch gelöst, dass der Rohling mittels der Hauptwalze und/oder der Kegelwalzen in Drehung versetzt wird, bevor die rotierenden Stegwalzen mit dem Rohling in Anlage gebracht werden. Auf diese Weise kann die Reibung und der Schlupf zwischen dem Rohling und den Stegwalzen verringert werden, so dass die Abnutzung der Stegwalzen vermindert ist.As for the method, the above-mentioned output is achieved by rotating the blank by means of the main roll and / or the tapered rollers before the rotating land rolls are brought into abutment with the blank. In this way, the friction and the slip between the blank and the web rolls can be reduced, so that the wear of the web rolls is reduced.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Drehzahl des Rohlings vor dem Aufsetzen der Stegwalzen so eingestellt wird, dass das Aufsetzen der Stegwalzen schlupffrei erfolgt. Dies ist erreicht, wenn die Umfangsgeschwindigkeit der Stegwalzen im Kontaktbereich gleich der Umfangsgeschwindigkeit des Rohlings ist, d.h. zwischen diesen beiden Bauteilen an der Kontaktfläche keine Geschwindigkeitsdifferenz gegeben ist.In a preferred embodiment of the invention, it is provided that the speed of the blank is set before placing the web rolls so that the placement of the web rolls is slip-free. This is achieved when the peripheral speed of the web rolls in the contact area is equal to the peripheral speed of the blank, i. there is no speed difference between these two components at the contact surface.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Verfahrens kann vorgesehen sein, dass die Drehzahl der Kegelwalzen so eingestellt wird, dass ein schlupffreier Kontakt des Rohlings mit den Kegelwalzen gegeben ist.In a further advantageous embodiment of the method according to the invention can be provided that the Speed of the tapered rollers is set so that a slip-free contact of the blank with the tapered rollers is given.

Wenn es beim Walzen des Rohlings zu keiner Überlagerung von Antriebsmomenten kommen soll, werden die Antriebsvorrichtungen der Hauptwalze und/oder der Kegelwalzen beim Walzvorgang in oben erläuterter Weise momentenfrei geschaltet.If there is no superimposition of drive torques when rolling the blank, the drive devices of the main roll and / or the tapered rollers during the rolling process in the manner explained above are switched torque-free.

Eine in den Figuren 1 und 2 dargestellte Walzvorrichtung 10 zum dornlosen Walzen von Rädern und Scheiben besitzt ein Walzengestell 11, das zwei übereinander im Abstand angeordnete Zentrierwalzen 12 und eine seitlich dazu versetzte Hauptwalze 13 aufweist. Die Zentrierwalzen 12 sind jeweils um senkrecht zur Zeichenebene gemäß Figur 1 verlaufende Achsen drehbar und insbesondere nicht angetrieben. Die Hauptwalze 13 ist um eine Achse D1 drehbar, die ebenfalls senkrecht zur Zeichenebene von Figur 1 verläuft, und ist mittels einer nur schematisch angedeuteten Antriebsvorrichtung 18 drehangetrieben. Durch eine Verstellvorrichtung 14 kann die Hauptwalze 13 in Richtung der Zentrierwalzen 12 verstellt und von diesen zurückgezogen werden. Dies ermöglicht es, einen kreisscheibenförmigen Rohling R so in das Walzengestell 11 einzusetzen, dass dessen Umfangsfläche U zwischen den beiden Zentrierwalzen 12 und der Hauptwalze 13 gehalten ist und mit diesen Walzen in Anlage steht. Der Rohling R ist dabei um eine senkrechte Zeichenebene in Figur 1 verlaufende Drehachse D2 drehbar.One in the Figures 1 and 2 shown rolling apparatus 10 for thornless rolling of wheels and discs has a roller frame 11, which has two superimposed spaced centering rollers 12 and a laterally offset main roller 13 thereto. The centering rollers 12 are each perpendicular to the plane according to FIG. 1 extending axes rotatable and in particular not driven. The main roller 13 is rotatable about an axis D 1 , which is also perpendicular to the plane of FIG. 1 runs, and is rotationally driven by means of a drive device 18 only schematically indicated. By an adjusting device 14, the main roller 13 can be adjusted in the direction of the centering rollers 12 and withdrawn from them. This makes it possible, a circular disc-shaped blank R in the Insert roller frame 11 that its peripheral surface U is held between the two centering rollers 12 and the main roller 13 and is in contact with these rollers. The blank R is about a vertical plane in FIG. 1 extending axis of rotation D 2 rotatable.

Um ein seitliches Herausfallen des Rohlings R aus dem Walzengestell 11 zu vermeiden, besitzt das Walzengestell 11 auf beiden Seiten des Rohlings R nicht angetriebene Seitenwalzen 20.In order to avoid lateral falling out of the blank R from the roll stand 11, the roll stand 11 has non-driven side rolls 20 on both sides of the blank R.

Im Umfangsbereich des Rohlings R sind auf dessen entgegengesetzten Seiten jeweils eine Kegelwalze 15 angeordnet, die mit den Seitenflächen S1 und S2 des Rohlings R in Anlage bringbar sind und von einer nur schematisch dargestellten Antriebsvorrichtung 19 angetrieben werden. Die Kegelwalzen 15 dienen zur Ausbildung des radial außenliegenden, umlaufenden Radkranzes des durch Walzen herzustellenden Rades.In the peripheral region of the blank R each have a conical roller 15 are arranged on the opposite sides thereof, which can be brought into abutment with the side surfaces S 1 and S 2 of the blank R and driven by a drive device 19 shown only schematically. The tapered rollers 15 serve to form the radially outer circumferential rim of the wheel to be produced by rolling.

Der zwischen einem nahe der Drehachse D2 gebildeten Nabenabschnitt und dem äußeren Radkranz liegende Stegbereich wird von Stegwalzen 16 angeformt, wobei auf jeder Seite des Rohlings zumindest eine Stegwalze 16 angeordnet ist. Die Stegwalzen 16 sind von einer nur schematisch dargestellten Antriebsvorrichtung 17 drehangetrieben.The web region formed between a hub section formed near the rotational axis D 2 and the outer wheel rim is formed by web rolls 16, wherein at least one web roll 16 is arranged on each side of the blank. The web rolls 16 are rotationally driven by a drive device 17 shown only schematically.

Die Antriebsvorrichtungen 17, 18 und 19 sind unabhängig voneinander ansteuerbar, wobei insbesondere vorgesehen ist, dass der Rohling R mittels der Hauptwalze 13 und/oder der Kegelwalzen 15 bereits in Drehung versetzt wird, bevor die rotierenden Stegwalzen 16 mit dem Rohling R vorzugsweise schlupffrei in Anlage gebracht werden.The drive devices 17, 18 and 19 are independently controllable, wherein it is provided in particular that the blank R by means of the main roller 13 and / or the tapered rollers 15 is already set in rotation before the rotating web rollers 16 with the blank R preferably without slipping in abutment to be brought.
