Description
Die Erfindung betrifft eine Vorrichtung zum Halten von wenigstens zwei Walze einer Walzmaschine und eine Walzmaschine.The invention relates to a device for holding at least two rolls of a rolling machine and a rolling machine.
Zum Umformen von Werkstücken aus einer Ausgangsform in eine gewünschte Zwischenform (Halbzeug, Vorformen) oder Endform (Fertigprodukt, Fertigformen) sind neben vielen anderen Verfahren auch Walzverfahren bekannt, die zu den Druckumformverfahren gezählt werden. Beim Walzen wird das Werkstück (Walzgut) zwischen zwei rotierenden Walzen angeordnet und durch Ausüben eines Umformdrucks durch die rotierenden Walzen in seiner Form verändert. Beim Profilwalzverfahren sind Werkzeugprofile am Umfang der Walzen angeordnet, die die Erzeugung entsprechender Profile im Werkstück ermöglichen. Beim Flachwalzen wirken die zylindrischen oder kegeligen Außenflächen der Walzen unmittelbar auf das Werkstück.For forming workpieces from a starting shape into a desired intermediate shape (semifinished product, preforming) or final shape (finished product, finished forms), there are, among many other processes, also rolling processes which are counted among the pressure forming processes. During rolling, the workpiece (rolling stock) is placed between two rotating rolls and changed in shape by exerting a forming pressure by the rotating rolls. When profile rolling process tool profiles are arranged on the circumference of the rollers, which allow the production of corresponding profiles in the workpiece. In flat rolling, the cylindrical or tapered outer surfaces of the rollers act directly on the workpiece.
Bezüglich der Relativbewegung der Werkzeuge oder Walzen einerseits und des Werkstückes andererseits unterteilt man Walzverfahren in Längswalzen, Querwalzen und Schrägwalzen. Beim Längswalzen wird das Werkstück senkrecht zu den Drehachsen der Walzen in einer translatorischen Bewegung und meist ohne Drehung durch den Zwischenraum zwischen den Walzen (Walzenspalt) bewegt. Beim Querwalzen bewegt sich das Werkstück nicht translatorisch bezüglich der Walzen oder deren Drehachsen, sondern dreht sich nur um seine eigene Achse, die üblicherweise eine Hauptträgheitsachse, insbesondere die Symmetrieachse bei einem rotationssymmetrischen Werkstück, ist. Bei Kombination beider Bewegungsarten beim Längswalzen und beim Querwalzen spricht man von Schrägwalzen. Die Walzen stehen dabei in der Regel schräg zueinander und zum Werkstück, das translatorisch und rotatorisch bewegt wird.With regard to the relative movement of the tools or rollers on the one hand and the workpiece on the other hand, one divides rolling processes in longitudinal rolls, transverse rolls and oblique rolls. During longitudinal rolling, the workpiece is moved perpendicular to the axes of rotation of the rollers in a translatory movement and usually without rotation through the gap between the rollers (nip). During transverse rolling, the workpiece does not translate with respect to the rollers or their axes of rotation, but rotates only about its own axis, which is usually a main axis of inertia, in particular the axis of symmetry in a rotationally symmetrical workpiece. When combining both types of movement during longitudinal rolling and cross rolling, one speaks of inclined rolls. The rollers are usually at an angle to each other and to the workpiece, which is translationally and rotationally moved.
Profillängswalzmaschinen für das Profillängswalzen von Vollkörpern werden üblicherweise als Reckwalzmaschinen bezeichnet, der dazugehörige Vorgang als Reckwalzen. Der austretende Querschnitt bleibt dabei nicht konstant. Die Walzen (auch: Reckwalzen) sind dabei so ausgebildet, dass sich der Profilquerschnitt in Umfangrichtung stetig oder sprunghaft ändert. Das Verfahren wird häufig angewendet, um für das Schmieden im Gesenk Zwischenformen mit günstiger Massenverteilung herzustellen.Longitudinal profile rolling mills for profile long rolls of solid bodies are commonly referred to as stretch rolling machines, the associated process as stretching rolls. The exiting cross section does not remain constant. The rollers (also: stretching rollers) are designed so that the profile cross section changes continuously or abruptly in the circumferential direction. The method is often used to produce intermediate shapes with favorable mass distribution for forging in the die.
Profilquerwalzmaschinen, bei denen zwei Walzen mit am Außenumfang angeordneten keilförmigen Profilwerkzeugen um zueinander parallele Drehachsen gleichsinnig rotieren, bezeichnet man mitunter auch als Querkeilwalzen. Die Werkzeuge weisen dabei eine keilförmige oder im Querschnitt dreieckförmige Geometrie auf und können entlang des Umfangs in ihrer axialen Abmessung in einer Richtung zunehmen und/oder schräg zur Drehachse der Walzen verlaufen.Profile transverse rolling machines, in which two rollers with wedge-shaped profile tools arranged on the outer circumference rotate in the same direction about axes of rotation parallel to one another, are sometimes referred to as transverse wedge rolling. The tools have a wedge-shaped or triangular in cross-section geometry and can increase along the circumference in its axial dimension in one direction and / or extend obliquely to the axis of rotation of the rollers.
Diese Querkeilwalzen oder Profilquerwalzen erlauben ein vielfältiges Umformen von Werkstücken in hoher Präzision oder Maßgenauigkeit. Die keilförmigen Werkzeuge können umlaufende Nuten und andere Verjüngungen in dem rotierenden Werkstück erzeugen. Durch den axialen Versatz in Umfangsrichtung oder die schräge Anordnung der Werkzeugkeile relativ zur Drehachse können beispielsweise axial zur Drehachse sich ändernde Strukturen und Verjüngungen im Werkstück erzeugt werden. Durch die Zunahme oder Abnahme des Außendurchmessers der Werkzeugkeile beim Verlauf um die Drehachse können in Kombination mit der schrägen Anordnung axial verlaufende Schrägen und kontinuierliche Übergänge zwischen zwei Verjüngungen unterschiedlichen Durchmessers im Werkstück erzeugt werden. Besonders geeignet sind Querkeilwalzen zum Herstellen von langgestreckten, rotationssymmetrischen Werkstücken mit Einschnürungen oder Erhöhungen wie Nocken oder Rippen.These cross wedge or cross-profile rollers allow a variety of forming workpieces in high precision or dimensional accuracy. The wedge-shaped tools can create circumferential grooves and other tapers in the rotating workpiece. By the axial offset in the circumferential direction or the oblique arrangement of the tool wedges relative to the axis of rotation, for example, axially changing structures and tapers can be produced in the workpiece to the rotation axis. By the increase or decrease of the outer diameter of the tool wedges when passing around the axis of rotation can be generated in combination with the oblique arrangement axially extending slopes and continuous transitions between two tapers of different diameters in the workpiece. Particularly suitable are cross wedge rollers for producing elongated, rotationally symmetrical workpieces with constrictions or elevations such as cams or ribs.
Aus
Aus der
Die Ausgestaltung von Walzmaschinen mit zwei Walzen erfordert üblicherweise, dass die Walzen nacheinander für die Montage in derselben Einführrichtung in eine Haltevorrichtung einzuführen sind. Dies hat zur Folge, dass eine erste zu montierende Walze an Halteeinrichtungen, die für eine zweite zu montierende Walze bestimmt sind, vorbei zu den für sie bestimmten Halteeinrichtungen eingeführt werden muss. Dadurch gestaltet sich die Montage und entsprechend auch die Demontage der Walzen schwierig. Ferner sind spezielle Ausbildungen der Halteeinrichtungen und Walzen erforderlich, um ein durchführen der ersten zu montierenden Walze durch die für die zweite zu montierende Walze bestimmten Halteeinrichtungen zu ermöglichen.The design of two-roller rolling machines usually requires that the rollers be successively inserted into a fixture for mounting in the same direction of insertion. As a result, a first roll to be mounted on holding devices intended for a second roll to be mounted must be introduced past the holding devices intended for it. As a result, the assembly and accordingly the disassembly of the rollers designed difficult. Furthermore, special embodiments of the holding devices and rollers are required to allow a carry out of the first roller to be mounted by the intended for the second roller to be mounted holding devices.

Weiter umfasst die Vorrichtung wenigstens eine, vorzugweise wenigstens zwei, insbesondere genau zwei erste Kupplungseinrichtungen für die erste Walze mit jeweils einem eingekuppelten Zustand und mit jeweils einem ausgekuppelten Zustand und wenigstens eine, vorzugsweise wenigstens zwei, insbesondere genau zwei zweite Kupplungseinrichtungen für die zweite Walze mit jeweils einem eingekuppelten Zustand und mit jeweils einem ausgekuppelten Zustand. Im eingekuppelten Zustand besteht eine drehmomentübertragende Verbindung zwischen der jeweiligen Halteeinrichtung und der ihr zugeordneten Walze. Der eingekuppelte Zustand kann somit auch als ein kraft- oder drehmomentübertragender Zustand bezeichnet werden. Der ausgekuppelte Zustand kann entsprechend auch als kraft- oder drehmomentloser Zustand bezeichnet werden, hier besteht keine drehmomentübertragende Verbindung zwischen der jeweiligen Halteeinrichtung und der ihr zugeordneten Walze.Furthermore, the device comprises at least one, preferably at least two, in particular exactly two first coupling devices for the first roller, each with a coupled state and each with a disengaged Condition and at least one, preferably at least two, in particular exactly two second coupling means for the second roller, each with a coupled state and each with a disengaged state. In the engaged state there is a torque transmitting connection between the respective holding device and its associated roller. The engaged state can thus also be referred to as a force or torque transmitting state. The disengaged state can also be referred to as a force or torque-free state, there is no torque-transmitting connection between the respective holding device and its associated roller.
Die Kupplungseinrichtungen weisen nun jeweils mindestens zwei korrespondierende Kupplungsteile auf, und zwar mindestens ein an der Halteeinrichtung vorgesehenes oder angeordnetes oder ausgebildetes halteeinrichtungsseitiges Kupplungsteil und mindestens ein an der Walze vorgesehenes walzenseitiges Kupplungsteil. Die jeweils korrespondierenden Kupplungsteile sind im eingekuppelten Zustand der Kupplungseinrichtungen form-und/oder kraftschlüssig miteinander verbunden, zur Erzeugung einer drehmomentübertragenden Verbindung jeder Halteeinrichtung mit der Walze. Dadurch wird beim Drehen wenigstens einer der Halteeinrichtungen über die Verbindungsflächen der Kupplungseinrichtung, an denen der Form-und/oder Kraftschluss wirksam ist, die Drehbewegung und das Drehmoment synchron auf die Walze übertragen, Gleichzeitig wird ein Herausfallen der Walze aus der Position zwischen den Halteeinrichtungen verhindert.The coupling devices now each have at least two corresponding coupling parts, namely at least one provided on the holding device or arranged or trained halteeinrichtungsseitiger coupling part and at least one provided on the roller roller-side coupling part. The respective corresponding coupling parts are positively and / or non-positively connected with each other in the engaged state of the coupling devices, for generating a torque-transmitting connection of each holding device with the roller. Thereby, when rotating at least one of the holding devices via the connecting surfaces of the coupling device, where the positive and / or frictional engagement is effective, the rotational movement and the torque transmitted synchronously to the roller, at the same time falling out of the roller from the position between the holding means is prevented ,
Im ausgekuppelten Zustand der Kupplungseinrichtungen ist die jeweilige Walze von den Halteeinrichtungen lösbar oder abnehmbar. Dies ermöglicht einen Austausch der Walzen oder das Neubestücken der Walzen mit Werkzeugen.In the disengaged state of the coupling devices, the respective roller of the holding devices is detachable or detachable. This allows replacement of the rolls or re-assembly of the rolls with tools.
Bei der erfindungsgemäßen Vorrichtung ist des Weiteren vorgesehen, dass erste Walze und zweite Walze nacheinander in derselben Einführrichtung zu montieren sind und die zuerst zu montierende erste Walze ist zwischen den zweiten Halteeinrichtungen und/oder den halteeinzichtungsseitigen Kupplungsteilen der zweiten Kupplungseinrichtungen der anschließend zu montierenden zweiten Walze hindurch zu führen. Insbesondere ist die erste Walze durch einen Zwischenraum zwischen den zweiten Halteeinrichtungen und/oder den halteeinrichtungsseitigen Kupplungsteilen der zweiten Kupplungseinrichtungen hindurch zu führen.In the apparatus of the present invention, it is further provided that the first roll and the second roll are successively mounted in the same insertion direction, and the first roll to be mounted first is between the second holding means and / or the holding-side coupling parts of the second coupling means to guide to be mounted second roller. In particular, the first roller is to pass through a gap between the second holding means and / or the holder-side coupling parts of the second coupling means.
Ferner ist bei der Vorrichtung vorgesehen, dass zumindest im ausgekuppelten Zustand, insbesondere nur im ausgekuppelten Zustand oder insbesondere im ausgekuppelten und im eingekuppelten Zustand, der Abstand zwischen den halteeinrichtungsseitigen Kupplungsteilen der ersten Kupplungseinrichtungen kleiner ist als der Abstand zwischen den halteeinrichtungsseitigen Kupplungsteilen der zweiten Kupplungseinrichtungen und die maximale Längserstreckung der ersten Walze zwischen ihren Stirnseite kleiner ist als die maximale Längserstreckung der zweiten Walze zwischen ihren Stirnseiten und die maximale Längserstreckung der ersten Walze zwischen ihren Stirnseiten kleiner ist als der Abstand zwischen den halteeinrichtungsseitigen Kupplungsteilen der zweiten Kupplungseinrichtungen. Insbesondere kann der Abstand zwischen den ersten Halteeinrichtungen kleiner ist als der Abstand zwischen den zweiten Halteeinrichtungen und die maximale Längserstreckung der ersten Walze zwischen ihren Stirnseiten kleiner als der Abstand zwischen den zweiten Halteeinrichtungen sein.Further, it is provided in the device that at least in the disengaged state, in particular only in the disengaged state or in particular in the disengaged and engaged state, the distance between the holder side coupling parts of the first coupling means is smaller than the distance between the holder side coupling parts of the second coupling means and the maximum longitudinal extent of the first roller between its end face is smaller than the maximum longitudinal extent of the second roller between its end faces and the maximum longitudinal extent of the first roller between its end faces is smaller than the distance between the holder-side coupling parts of the second coupling means. In particular, the distance between the first holding devices may be smaller than the distance between the second holding devices and the maximum longitudinal extension of the first roller between their end faces may be smaller than the distance between the second holding devices.
Unter Abstand wird dabei die minimale Entfernung zwischen den beiden jeweils betrachteten Teilen bzw. Komponenten angesehen. Die Längserstreckung der Walze ist ihre Erstreckung parallel zur Drehrichtung. Die halteeinrichtungsseitigen Kupplungsteile können als Teil der jeweiligen Halteeinrichtung oder als eigenständiges Teil, das an der jeweiligen Halteeinrichtung angeordnet ist, verstanden werden. Die walzenseitigen Kupplungsteile können als Teil der jeweiligen Walze oder als eigenständiges Teil, das an der jeweiligen Walze angeordnet ist, verstanden werden.At a distance, the minimum distance between the two parts or components considered is considered. The longitudinal extent of the roller is its extension parallel to the direction of rotation. The holder-side coupling parts can be understood as part of the respective holding device or as a separate part, which is arranged on the respective holding device. The roller-side coupling parts can be understood as part of the respective roller or as an independent part, which is arranged on the respective roller.
Die Vorteile der Erfindung liegen insbesondere darin, dass aufgrund der unterschiedlichen Abmessungen die erste Walze problemlos an den Halteeinrichtungen für die zweite Walze vorbeigeführt werden kann. Das Einführen der ersten Walze und entsprechend auch das Ausführen der ersten Walze an den für die zweite Walze bestimmten Halteeinrichtungen bzw. Kupplungseinrichtungen vorbei ist somit in einfacher Weise möglich. Insbesondere ist es aufgrund des gemäß der Erfindung verwirklichten Abstandes zwischen den für die zweite Walze bestimmten walzenseitigen Kupplungsteilen und der ersten Walze beim Durchführen der ersten Walze durch die zweiten Halteeinrichtungen nicht mehr erforderlich, speziell ausgebildete Nuten und Vorsprünge bzw. Positionierelemente aufwendig, mühsam und vorsichtig aneinander vorbeizuführen.The advantages of the invention are, in particular, that due to the different dimensions, the first roller can easily be guided past the holding devices for the second roller. The introduction of the first roller and, correspondingly, the execution of the first roller on the holders or coupling devices intended for the second roller over is thus possible in a simple manner. In particular, due to the distance between the roller-side coupling parts intended for the second roller and the first roller when passing the first roller through the second holding devices, it is no longer necessary, specially formed grooves and projections or positioning elements to be complicated, tedious and careful passing out.
Wesentlicher Vorteil der Erfindung ist daher die einfache Montier- und Demontierbarkeit der Walzen.An essential advantage of the invention is therefore the easy mounting and dismounting of the rollers.
Eine Weiterbildung sieht vor, dass zumindest eine der ersten Halteeinrichtungen und/oder zumindest eines der halteeinrichtungsseitigen Kupplungsteile der ersten Kupplungseinrichtungen weiter hervorragt als zumindest eine der zweiten Halteeinrichtung und/oder zumindest eines der halteeinrichtungsseitigen Kupplungsteile der zweiten Kupplungseinrichtungen.A further development provides that at least one of the first holding devices and / or at least one of the holder-side coupling parts of the first coupling devices project further than at least one of the second holding device and / or at least one of the holder-side coupling parts of the second coupling devices.
Bevorzugt sind erste Walze und zweite Walze im eingekuppelten Zustand nebeneinander angeordnet, insbesondere, in Schwerkraftrichtung gesehen, übereinander angeordnet. Die erste Walze ist somit eine Unterwalze und die zweite Walze eine Oberwalze. In diesem Fall werden die Walzen von oben in die Haltevorrichtung eingeführt.In the engaged state, the first roller and the second roller are preferably arranged next to one another, in particular, when viewed in the direction of gravity, arranged one above the other. The first roller is thus a lower roller and the second roller is a top roller. In this case, the rollers are inserted from above into the holding device.
Eine bevorzugte Weiterbildung sieht ferner vor, dass die Drehachsen der ersten Walze und der zweiten Walze zumindest im Wesentlichen parallel zueinander gerichtet sind.A preferred embodiment further provides that the axes of rotation of the first roller and the second roller are at least substantially parallel to each other.
Um zwischen dem eingekuppelten Zustand und dem ausgekuppelten Zustand der Kupplungseinrichtungen umzuschalten oder zu wechseln, ist vorzugsweise wenigstens eine Stelleinrichtung zum (insbesondere automatischen) Stellen wenigstens einer der ersten Halteeinrichtungen und der zweiten Halteeinrichtungen vorgesehen,
- a) wobei in einer Zustellbewegung die jeweiligen Kupplungseinrichtungen in einen eingekuppelten Zustand überführbar sind, und
- b) wobei in einer Fortstellbewegung die jeweiligen Kupplungseinrichtungen in einen ausgekuppelten Zustand überführbar sind.
- a) wherein in a feed movement, the respective coupling devices can be converted into a coupled state, and
- b) wherein in a continuous movement, the respective coupling devices can be converted into a disengaged state.
Bevorzugt ist die Zustellbewegung und/oder die Fortstellbewegung eine Bewegung axial und/oder radial zur jeweiligen Drehachse.Preferably, the feed movement and / or the advancing movement is a movement axially and / or radially to the respective axis of rotation.
Um zwischen dem eingekuppelten Zustand und dem ausgekuppelten Zustand der Kupplungseinrichtungen umzuschalten oder zu wechseln, ist alternativ oder additiv wenigstens eine Stelleinrichtung zum (insbesondere automatischen) Stellen des halteeinrichtungsseitigen Kupplungsteiles mindestens einer der ersten Kupplungseinrichtungen und/oder mindestens einer der zweiten Kupplungseinrichtungen vorgesehen,
- a) wobei in einer Zustellbewegung die jeweiligen Kupplungseinrichtungen in einen eingekuppelten Zustand überführbar sind, und
- b) wobei in einer Fortstellbewegung die jeweiligen Kupplungseinrichtungen in einen ausgekuppelten Zustand überführbar sind.
- a) wherein in a feed movement, the respective coupling devices can be converted into a coupled state, and
- b) wherein in a continuous movement, the respective coupling devices can be converted into a disengaged state.
Bevorzugt ist auch hier die Zustellbewegung und/oder die Fortstellbewegung eine Bewegung axial und/oder radial zur jeweiligen Drehachse.Here, too, the feed movement and / or the advancing movement is preferably a movement axially and / or radially to the respective axis of rotation.
Zum Montieren einer Walze zwischen den jeweiligen beiden Halteeinrichtungen wird die Walze in einem ersten Schritt im ausgekuppelten Zustand der Kupplungseinrichtungen in eine Position zwischen den beiden Halteeinrichtungen verbracht und anschließend werden in einem zweiten Schritt die zugehörigen Kupplungseinrichtungen durch Zustellen wenigstens einer der beiden Halteeinrichtungen und/oder wenigstens eines der halteeinrichtungsseitigen Kupplungsteile zur Walze in ihren eingekuppelten Zustand übergeführt. Die Walze ist dann sicher zwischen den Halteeinrichtungen gehalten. Umgekehrt werden zum Demontieren der Walze von den Halteeinrichtungen die beiden Kupplungseinrichtungen zunächst aus ihrem eingekuppelten Zustand in ihren ausgekuppelten Zustand übergeführt durch Fortbewegen wenigstens einer der beiden Halteeinrichtungen und/oder wenigstens eines der halteeinrichtungsseitigen Kupplungsteile von der Walze weg und anschließend wird die Walze in eine Position außerhalb der beiden Halteeinrichtungen gebracht.For mounting a roller between the respective two holding devices, the roller is moved in a first step in the disengaged state of the coupling devices in a position between the two holding devices and then in a second step, the associated coupling devices by delivering at least one of the two holding devices and / or at least one of the holder-side coupling parts to the roller transferred to its engaged state. The roller is then securely held between the holding devices. Conversely, to disassemble the roller from the holding means, the two coupling means are first transferred from their engaged state to their disengaged state by advancing at least one of the two retainers and / or at least one of the holder side coupling members away from the roller, and then the roller is moved to an outside position brought the two holding devices.
Vorzugsweise sind ferner zweite Walze und erste Walze nacheinander in derselben Ausführrichtung zu demontieren und die als zweites zu demontierende erste Walze ist zwischen den zweiten Halteeinrichtungen für die vorausgehend zu demontierende zweite Walze, das heißt durch einen Zwischenraum zwischen den zweiten Halteeinrichtungen, hindurch zu führen .Further, it is preferable to disassemble the second roller and the first roller sequentially in the same direction of execution, and the second roller to be disassembled second is located between the second holders for the previously to be dismantled second roller, that is to pass through a gap between the second holding means, therethrough.
Eine zweckmäßige Weiterbildung sieht vor, dass an den jeweils korrespondierenden Kupplungsteilen der Kupplungseinrichtungen an den einander zugewandten Seiten Anschlagflächen angeordnet oder angebracht sind, die im eingekuppelten Zustand der Kupplungseinrichtungen aneinander anliegen, insbesondere form- und/oder kraftschlüssig. Die Anschlagflächen begrenzen die Zustellbewegung und fixieren die Walze zwischen den Halteeinrichtungen.An expedient development provides that abutment surfaces are arranged or attached to the respective corresponding coupling parts of the coupling devices on the mutually facing sides, which abut each other in the engaged state of the coupling devices, in particular positive and / or non-positive. The stop surfaces limit the feed movement and fix the roller between the holding devices.
Bevorzugt sind Walzen und Halteeinrichtungen undKupplungseinrichtungen so ausgebildet, dass die zuerst zu montierende erste Walze zwischen den zweiten Halteeinrichtungen der anschließend zu montierenden zweiten Walze hindurch führbar ist und erst in ihrer gewünschten Stellung zwischen den zugehörigen ersten Halteeinrichtungen positionierbar ist.Rollers and holding devices and coupling devices are preferably designed so that the first roller to be mounted first can be guided between the second holding devices of the subsequently mounted second roller and can only be positioned in its desired position between the associated first holding devices.
Zweckmäßig ist auch, wenn die erste Walze unverwechselbar zwischen den ersten Halteeinrichtungen einbaubar ist und die zweite Walze unverwechselbar zwischen den zweiten Halteeinrichtungen einbaubar ist, insbesondere durch entsprechende Ausbildung der zugehörigen Kupplungseinrichtungen.It is also useful if the first roller is unmistakably installed between the first holding means and the second roller is unmistakably installed between the second holding means, in particular by appropriate design of the associated coupling means.
Die Walzmaschine gemäß der Erfindung umfasst wenigstens zwei um jeweils eine Drehachse rotierbare oder rotierende, insbesondere mit Werkzeugen bestückbare oder bestückte, Walzen (oder.: Arbeitswalzen), wenigstens einen Rotationsantrieb zum Rotieren der Walzen zumindest während einer Umformphase zum Umformen eines zwischen den Walzen anordenbaren oder angeordneten Werkstücks und eine Vorrichtung gemäß der Erfindung zum Halten der Walzen.

Es kann sich aber ebenso um mit entsprechenden Formgebungswerkzeugen ausgerüstete Walzen handeln.The rolling machine according to the invention comprises at least two rollers (or work rolls) rotatable or rotating about one axis of rotation, in particular, equipped with tools, at least one rotary drive for rotating the rolls at least during a forming phase for forming an or between the rolls arranged workpiece and a device according to the invention for holding the rollers. The rollers may be smooth-surfaced rollers without the need for mounting or forming special forming tools. But it may also be treated with appropriate shaping tools rollers.
Unter dem Begriff "Umformen" wird jede Umwandlung der Form eines Werkstückes in eine andere Form verstanden, wie auch eingangs beschrieben, einschließlich Vorformen und Fertigformen. Die Drehachsen der Walzen sind als geometrische oder mathematische Achsen im (euklidischen, dreidimensionalen) Raum zu verstehen, um die sich die Walzen drehen.The term "forming" is understood to mean any transformation of the shape of a workpiece into another form, as also described in the introduction, including preforms and preforms. The axes of rotation of the rollers are to be understood as geometric or mathematical axes in the (Euclidean, three-dimensional) space around which the rollers rotate.
Die Walzmaschine umfasst im Allgemeinen Lagereinrichtungen für jede Halteeinrichtung, in denen die Halteeinrichtungen der Walzen drehbar gelagert sind.The rolling machine generally comprises storage devices for each holding device in which the holding devices of the rollers are rotatably mounted.
Die Drehachsen der in den Halteeinrichtungen montierten Walzen sind im Allgemeinen im Wesentlichen parallel zueinander gerichtet und/oder im Wesentlichen, in Schwerkraftrichtung gesehen, übereinander und/oder im Wesentlichen senkrecht zur Schwerkraftrichtung angeordnet.The axes of rotation of the rollers mounted in the holding devices are generally directed substantially parallel to one another and / or substantially, as seen in the direction of gravity, one above the other and / or arranged substantially perpendicular to the direction of gravity.
In einer Ausführungsform ist die Walzmaschine als Flachwalzmaschine ausgebildet. In einer anderen Ausführungsform ist die Walzmaschine als Profilwalzmaschine, beispielsweise Profillängswalzmaschine oder Profilquerwalzmaschine oder Querkeilwalzmaschine ausgebildet, deren grundsätzlicher Aufbau eingangs beschrieben wurde. Insbesondere weisen die Walzen Profil-oder Keilwerkzeuge auf und rotieren gleichsinnig zueinander, wobei das Werkstück sich nur um eine eigene Achse dreht und nicht von den Walzen translatorisch transportiert wird - im Gegensatz zum Längswalzen. Die Werkzeuge auf den Walzen sind insbesondere im Querschnitt keilförmig oder dreieckförmig und nehmen entlang des Umfangs in ihrer radialen Abmessung in einer Richtung zu und/oder verlaufen schräg zur Drehachse der zugehörigen Walze.In one embodiment, the rolling machine is designed as a flat rolling machine.
