Description

Die Erfindung betrifft eine Poliervorrichtung zum Polieren eines Bauteils, mit einem länglichen Polierelement.The invention relates to a polishing device for polishing a component, with an elongate polishing element.

Stand der TechnikState of the art

Im Stand der Technik sind Verfahren und Vorrichtungen zum Nachschleifen der insbesondere in Warmbandwalzgerüsten eingebauten Walzen bekannt. Durch den Bandkontakt nehmen die Walzen Zunder und andere Aufbackungen an. Diese Verunreinigungen werden beim nächsten Band auf die Oberfläche des zu wickelnden Bandes aufgedrückt. Es kommt so zu Markierungen auf dem fertigen Warmband. Um dieses zu verhindern, werden die Walzen üblicherweise mit einer Polier- bzw. Schleifeinrichtung versehen, welche die Aufbackungen an den Walzen in regelmäßigen Abständen herunterpolieren.The prior art discloses methods and devices for regrinding the rolls, which are installed in particular in hot strip rolling mills. Due to the band contact the rollers take on tinder and other caking. These impurities are pressed on the next band on the surface of the belt to be wound. It comes to markings on the finished hot strip. To prevent this, the rollers are usually provided with a polishing or grinding device, which polish down the caking on the rollers at regular intervals.

So beschreibt die EP 0154319 B1 eine Walzenschleifvorrichtung für Walzwerke, mit einem Gehäuse zum Positionieren der Walzenschleifvorrichtung in der Nähe einer Walze. Mittels einer Gehäuseführung, die sich entlang der Walzenachse erstreckt, und einem Gehäuse, dass in Querrichtung bewegbar an der Gehäuseführung befestigt ist, ist die Einrichtung quer zur Walze verschiebbar. In dem Gehäuse ist ein Schleifstein angeordnet, der relativ zur Walzenachse hin und her bewegbar ist.That's how it describes EP 0154319 B1 a roll grinding apparatus for rolling mills, comprising a housing for positioning the roll grinding apparatus in the vicinity of a roll. By means of a housing guide, which extends along the roll axis, and a housing, which is mounted in the transverse direction movable on the housing guide, the device is displaceable transversely to the roller. In the housing, a grindstone is arranged, which is movable relative to the roll axis back and forth.

Die EP 0824975 A1 beschreibt ein Verfahren und eine Vorrichtung zum Nachschleifen der in Warmbandwalzgerüsten eingebauten Walzen, mit mindestens einem topfförmigen, rotierend angetriebenen Schleifwerkzeug, das parallel zur Walzenachse oszillierend bewegbar ist. Dabei wird die vorgesehene Anpresskraft des Schleifwerkzeuges an die Walze mittels den Verschiebeantrieben zugeführter Druckluft aufgebracht.The EP 0824975 A1 describes a method and a device for regrinding the rollers installed in hot strip rolling mills, with at least one cup-shaped, rotationally driven grinding tool which is oscillatingly movable parallel to the roll axis. In this case, the intended contact pressure of the grinding tool is applied to the roller by means of the displacement drives supplied compressed air.

Die EP 0573035 B1 beschreibt eine Watzenschteifanordnung, die eine zu einer Walze eines Walzenpaares hin gerichtete Plan-Schleifscheibe zum Schleifen dieser Walze aufweist. Die Schleifscheibe wird über eine Schleifscheiben-Antriebseinrichtung mittels einer Spindel gedreht, wobei zum Andrücken der Schleifscheibe an die Walze eine Schleifscheiben-Vorschubeinrichtung vorgesehen ist. Zum axialen Verschieben der Schleifscheibe ist eine zusätzliche Verfahreinrichtung vorgesehen ist.The EP 0573035 B1 describes a Watzenabtifanordnung having a directed to a roll of a pair of rollers plan grinding wheel for grinding this roller. The grinding wheel is rotated by means of a spindle via a grinding wheel drive device, wherein a grinding wheel feed device is provided for pressing the grinding wheel onto the roller. For axial displacement of the grinding wheel, an additional traversing device is provided.

Nachteil dieser oben genannten bekannten Schleifvorrichtungen ist die aufwendige Konstruktion der Antriebseinheiten zum Anstellen und Bewegen der Schleifvorrichtung gegen das Bauteil, sowie der notwendige große Einbauraum zur Anordnung der Schleifvorrichtung mit den Antriebseinheiten und den Steuerelementen.Disadvantage of these known grinding devices is the complex construction of the drive units for hiring and moving the grinding device against the component, as well as the necessary large installation space for the arrangement of the grinding device with the drive units and the controls.

Beschreibung der ErfindungDescription of the invention

Aufgabe der Erfindung ist es, eine Poliervorrichtung für Bauteile bereitzustellen, die im Hinblick auf die Wartungsfreundlichkeit und Nachrüstbarkeit flexibel, kompakt und kostengünstig vielseitig einsetzbar ist und die Qualität des Poliervorgangs verbessert.The object of the invention is to provide a polishing device for components that is flexible, compact and cost-effective versatile in terms of ease of maintenance and retrofitting and improves the quality of the polishing process.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Dieser ist besonders dadurch gekennzeichnet, dass ein Druckelement in mehrere längliche Teilschläuche ausgebildet ist, die entweder einzeln oder über eine gemeinsame Ankopplung gleichzeitig mit Druck beaufschlagbar sind. Mit dieser erfindungsgemäßen Anordnung eines schlauchförmigen Druckelementes in Verbindung mit dem in benachbarte Teilsegmente aufgeteilten Polierelement ist es möglich, innerhalb eines kleinen Einbauraums in Längserstreckung eines Bauteils eine gleichmäßige Kraft zum Andrücken des Polierelementes gegen das Bauteil einzuleiten. Vorteil ist die lückenlose Konturanpassung an die Oberfläche des Bauteils in Längsrichtung bei identischen Andruckkräften auch bei Bauteilen mit nicht gradlinigen oder nicht ebenen Oberflächen. Durch die kompakte Baugröße der Poliereinrichtung ist die Nachrüstung in vorhandenen Anlagen flexibel und kostengünstig möglich. Aufgrund der wenigen Bauteile ist diese Poliereinrichtung wartungsfreundlich aufgebaut.This object is achieved by the features of claim 1. This is particularly characterized in that a pressure element is formed in a plurality of elongated partial tubes, which are acted upon by pressure either individually or via a common coupling. With this inventive arrangement of a tubular pressure element in conjunction with the divided into adjacent sub-segments polishing element, it is possible within a small installation space in the longitudinal extension of a component, a uniform force for pressing the polishing against to initiate the component. The advantage is the seamless contour adaptation to the surface of the component in the longitudinal direction with identical pressure forces even for components with non-rectilinear or non-planar surfaces. Due to the compact size of the polishing device retrofitting in existing systems is flexible and inexpensive possible. Due to the few components, this polishing device is designed to be easy to maintain.

Gemäß einem ersten Ausführungsbeispiel ist das Druckelement so ausgebildet, dass es mit einem Druckmittel beaufschlagbar ist. Anlagenbedingt ist es somit möglich, je nach bereitgestellten Mitteln den Anpressdruck für das Polierelement hydraulisch oder pneumatisch aufzubringen, was gerade bei Nachrüstungen in vorhandene Anlagen von Vorteil ist.According to a first embodiment, the pressure element is designed so that it can be acted upon by a pressure medium. As a result of the system, it is thus possible, depending on the means provided, to apply the contact pressure for the polishing element hydraulically or pneumatically, which is particularly advantageous for retrofitting into existing installations.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass eine Steuerung zum Steuern der Druckkraft des Druckelementes angeordnet ist. Je nach Material des zu polierenden Bauteils ist es erfindungsgemäß möglich, den entsprechenden Anpressdruck für das Polierelement vorzugeben.In a further embodiment of the invention it is provided that a control for controlling the pressure force of the pressure element is arranged. Depending on the material of the component to be polished, it is inventively possible to specify the corresponding contact pressure for the polishing element.

Nach einem weiteren Ausgestaltungsmerkmal ist vorgesehen, dass das Polierelement innerhalb des Gehäuses an seitlichen Führungsflächen verschiebbar angeordnet ist. Vorteil hierbei ist, dass das Gehäuse als Einbauraum und gleichzeitig auch als Führung für das Polierelement dient, um damit ein geführtes, kontrolliertes und stabilisiertes Anstellen des Polierelementes gegen das Bauteil zu gewährleisten. Diese Doppelfunktion des Gehäuses spart außerdem zusätzlichen Einbauraum.According to a further embodiment feature, it is provided that the polishing element is displaceably arranged within the housing on lateral guide surfaces. The advantage here is that the housing serves as an installation space and at the same time as a guide for the polishing element in order to ensure a guided, controlled and stabilized adjustment of the polishing element against the component. This dual function of the housing also saves additional installation space.

Weiterhin sieht die Erfindung vor, dass das Polierelement in dem Gehäuse derart angeordnet ist, dass nur ein Teilbereich auf der Arbeitsseite des Polierelementes mit dem Überstand A aus dem Gehäuse herausragt. Hierdurch wird verhindert, dass unnötiger Bauraum für das Anstellen des Polierelementes in Anspruch genommen wird. Durch den kurzen Überstand des Polierelementes wird das von dem Bauteil auf das Polierelement übertragene Biegemoment gering gehalten. Vorteilhafterweise kann das Polierelement damit kleiner dimensioniert werden.Furthermore, the invention provides that the polishing element is arranged in the housing such that only a portion protrudes on the working side of the polishing element with the projection A from the housing. This prevents that unnecessary space for the employment of the polishing element is claimed. Due to the short projection of the polishing element, the bending moment transmitted from the component to the polishing element becomes low held. Advantageously, the polishing element can thus be dimensioned smaller.

Nach einem weiteren Ausgestaltungsmerkmal ist vorgesehen, dass an dem Gehäuse ein Anschlag angeordnet ist, der den Verschiebeweg des Polierelementes begrenzt. Das Polierelement wird somit sicher in dem Gehäuse geführt und nur bis zur maximal möglichen Arbeitslänge des Bauteils angestellt.According to a further embodiment feature, it is provided that a stop is arranged on the housing, which limits the displacement of the polishing element. The polishing element is thus safely guided in the housing and employed only up to the maximum possible working length of the component.

In einer Ausgestaltung der Erfindung ist vorgesehen, dass das Polierelement als Schleifstein ausgebildet ist.In one embodiment of the invention it is provided that the polishing element is designed as a grindstone.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass das Polierelement in Umfangsrichtung des Bauteils mehrteilig in Form von Teilsegmenten ausgebildet und lokal individuell anstellbar ist. Mit dieser erfindungsgemäßen Anordnung ist das Polierelement dem Profil bzw. der Kontur des Bauteils nicht nur in Richtung der Längsachse z anpassbar, sondern auch über den Umfang verteilt radial zur Oberfläche des Bauteils anstellbar. Daraus ergibt sich ein qualitativ hochwertiges, gleichmäßiges Schriftbild.In a further embodiment of the invention it is provided that the polishing element is formed in the circumferential direction of the component in several parts in the form of sub-segments and locally adjustable individually. With this arrangement according to the invention, the polishing element is the profile or the contour of the component not only in the direction of the longitudinal axis z adaptable, but also distributed over the circumference radially to the surface of the component can be adjusted. This results in a high quality, uniform typeface.

Gemäß einem Ausführungsbeispiel ist vorgesehen, dass das Bauteil in Form einer Walze ausgebildet ist.According to one embodiment, it is provided that the component is designed in the form of a roller.

Die Erfindung wird nachfolgend unter Bezugnahme auf die Figuren detailliert beschrieben. Es zeigen:

Figur 1
die Poliereinrichtung, bestehend aus einem Gehäuse, einem Druckelement und einem länglichen Polierelement, welches gegen ein Bauteil anstellbar ist; und
Figur 2
die Anstellung der Poliereinrichtung in Richtung der Längsachse des Bauteils mit einem schlauchförmigen Druckelement.
The invention will be described in detail below with reference to the figures. Show it:
FIG. 1
the polishing device, consisting of a housing, a pressure element and an elongate polishing element, which is adjustable against a component; and
FIG. 2
the employment of the polishing device in the direction of the longitudinal axis of the component with a tubular pressure element.

Die Figur 1 zeigt eine Poliervorrichtung 100 für ein Bauteil 200, mit einem länglichen Polierelement 110, welches parallel zur Längsachse z des Bauteils 200 gegen die Oberfläche 205 des Bauteils 200 anstellbar ist. Zur Aufnahme des Polierelementes 110 und eines Druckelementes 130, welches das Polierelement 110 gegen das Bauteil 200 drückt, ist ein Gehäuse 120 angeordnet, in welchem zwischen einer Auflagefläche 123 des Gehäuses 120 und dem Polierelement 110 das Druckelement 130 gelagert ist. Dabei ist erfindungsgemäß vorgesehen, dass das Druckelement 130 als mindestens ein druckbeaufschlagbarer Schlauch ausgebildet ist und der Druck mit einem Druckmittel hydraulisch oder pneumatisch aufgebracht wird. Eine Steuerung 300 steuert den Anpressdruck des Druckelementes 130 gegen das Polierelement 110.The FIG. 1 shows a polishing apparatus 100 for a component 200, with an elongated polishing element 110, which is parallel to the longitudinal axis z of the component 200 against the surface 205 of the component 200 can be adjusted. For receiving the polishing element 110 and a pressure element 130, which presses the polishing element 110 against the component 200, a housing 120 is arranged, in which between a bearing surface 123 of the housing 120 and the polishing element 110, the pressure element 130 is mounted. It is inventively provided that the pressure element 130 is formed as at least one pressurizable hose and the pressure is applied hydraulically or pneumatically with a pressure medium. A controller 300 controls the contact pressure of the pressure element 130 against the polishing element 110.

Je nach Länge des zu polierenden Bauteils ist als eine nicht dargestellte Alternative denkbar, das Druckelement 130 in mehrere längliche Teilschläuche auszubilden, die entweder einzeln oder über eine gemeinsame Ankopplung gleichzeitig mit Druck beaufschlagbar sind. Die Anordnung mehrerer Schläuche als Druckelement 130 in Längsrichtung zur Längsachse z des Bauteils bietet den Vorteil, dass das Polierelement 110 der Oberflächenkontur des Bauteils 200 über eine große Gesamtlänge flexibel und gleichmäßig anzustellen ist. Erfindungsgemäß ist vorgesehen, dass jedes Druckelement 130 vorzugsweise mit einer separaten Steuerung 300 zum Einstellen des Anpressdrucks des Polierelementes 110 verbunden ist. Nach Figur 1 ist das Polierelement 110 in Umfangsrichtung des Bauteils 200 als einteiliges Element dargestellt. Eine Variante ist aber auch, dass das Polierelement 110 auch in Umfangsrichtung des Bauteils 200 mehrteilig ausgebildet ist. Die Poliervorrichtung 100 kann sich damit auch einer Krümmung in Umfangsrichtung des Bauteils anpassen und liegt dadurch auch in diesen Fällen flächig auf der Oberfläche 205 des Bauteils 200 auf. Daraus resultieren eine bessere Ausnutzung der Polierelemente 110 sowie ein verbessertes, gleichmäßiges Schliffbild.Depending on the length of the component to be polished is conceivable as an alternative, not shown, to form the pressure element 130 into a plurality of elongated partial hoses, which are acted upon at the same time with pressure either individually or via a common coupling. The arrangement of several hoses as a pressure element 130 in the longitudinal direction to the longitudinal axis z of the component has the advantage that the polishing element 110 of the surface contour of the component 200 over a large overall length can be made flexible and uniform. According to the invention, it is provided that each pressure element 130 is preferably connected to a separate control 300 for adjusting the contact pressure of the polishing element 110. To FIG. 1 the polishing element 110 is shown in the circumferential direction of the component 200 as a one-piece element. However, a variant is also that the polishing element 110 is formed in several parts in the circumferential direction of the component 200. The polishing apparatus 100 can thus also adapt to a curvature in the circumferential direction of the component and, as a result, lies flat on the surface 205 of the component 200 even in these cases. This results in better utilization of the polishing elements 110 and an improved, uniform microsection.

Das Polierelement ist in dem Gehäuse 120 derart angeordnet, dass es mit einem möglichst geringen Überstand A aus dem Gehäuse hervorsteht. Dadurch wird das auf das Polierelement 110 eingeleitete Biegemoment beim Andrücken der Poliervorrichtung 100 gegen die Bauteil 200 möglichst gering gehalten. Über eine Führungsfläche 122 wird das Polierelement 110 in dem Gehäuse 120 geführt. Damit ist ein stabilisiertes und lineares Anstellen des Polierelementes 110 möglich. In dem Gehäuse 120 ist ein erster Anschlag 121 für das Polierelement 110 angeordnet, gegen den das Polierelement 110 mit einem zweiten Anschlag 124 anstößt. In diesem Fall ist der maximale Arbeitsweg des Polierelementes 110 erreicht und ein Austausch des Polierelementes 110 erforderlich. Dieser erfolgt üblicherweise durch ein einfaches seitliches Herausschieben des Polierelementes 110 aus dem Gehäuse 120.The polishing element is arranged in the housing 120 such that it protrudes with the smallest possible projection A from the housing. As a result, the bending moment introduced on the polishing element 110 is kept as low as possible when the polishing device 100 is pressed against the component 200. Via a guide surface 122, the polishing element 110 is guided in the housing 120. For a stabilized and linear adjustment of the polishing element 110 is possible. In the housing 120, a first stop 121 is arranged for the polishing element 110, against which the polishing element 110 abuts with a second stop 124. In this case, the maximum working path of the polishing element 110 is reached and an exchange of the polishing element 110 is required. This is usually done by a simple lateral pushing out of the polishing element 110 from the housing 120th

Die Figur 2 beschreibt in Richtung der Längsachse z das Bauteil 200 mit der Poliervorrichtung 100, welche gegen die Oberfläche 205 des Bauteils angestellt ist. Dabei ist das Polierelement 110 in Richtung der Längsachse z des Bauteils 200 in benachbarte Teilsegmente 110-1, 110-2, ... 110-n ausgebildet. Diese Anordnung gewährleistet eine flexible, der Walzenkontur entsprechend angepasste Anstellung der Teilsegmente ohne Zwischenlücken. Zwischen dem Gehäuse 120 und dem Polierelement 110 ist das Druckelement 130 zum Anstellen und Andrücken des Polierelementes 110 gegen die Walzenoberfläche 205 angeordnet.The FIG. 2 describes in the direction of the longitudinal axis z, the component 200 with the polishing apparatus 100, which is employed against the surface 205 of the component. In this case, the polishing element 110 is formed in the direction of the longitudinal axis z of the component 200 in adjacent sub-segments 110-1, 110-2,... 110-n. This arrangement ensures a flexible, the roller contour appropriately adjusted employment of the sub-segments without gaps. Between the housing 120 and the polishing element 110, the pressure element 130 for setting and pressing of the polishing element 110 against the roller surface 205 is arranged.

Die in den Figuren 1 und 2 dargestellte Poliervorrichtung 100 ist besonders verwendbar zum Polieren einer Walze innerhalb einer Walzstraße zur Herstellung von Warmband. Dabei wird die Poliervorrichtung 100 bevorzugt eingesetzt zum Polieren der Andrückrollen einer Warmbandhaspel, welche das Warmband um einen rotierenden Haspeldorn biegen. Ein weiterer vorteilhafter Einsatzbereich der erfindungsgemäßen Poliervorrichtung 100 ist innerhalb einer Richtmaschine für Walzgut, zum Polieren der Richtrollen. Aufgrund des geringen Bauraums und der einfachen konstruktiven und kostengünstigen Gestaltung der Poliervorrichtung 100, sind aber auch andere technische Anwendungen denkbar, wie zum Beispiel der Einsatz innerhalb von NE-Metall-Walzanlagen, Holzbearbeitungsmaschinen, Bäckereimaschinen, Druckmaschinen, oder auch in Zementwerken. Überall dort, wo die das Produkt führenden Rollen Verunreinigungen ausgesetzt sind, kann die Oberfläche der Rollen oder Walzen mit der erfindungsgemäßen Poliervorrichtung 100 poliert oder geschliffen werden.The in the FIGS. 1 and 2 The polishing apparatus 100 illustrated is particularly useful for polishing a roll within a rolling mill to produce hot strip. In this case, the polishing apparatus 100 is preferably used for polishing the pressure rollers of a hot strip reel, which bend the hot strip around a rotating coiler mandrel. Another advantageous application of the polishing device 100 according to the invention is within a straightening machine for rolling, for polishing the straightening rollers. Due to the small space and the simple constructive and cost-effective design of the polishing apparatus 100, but other technical applications are conceivable, such for example, use in non-ferrous metal rolling mills, woodworking machines, bakery machines, printing presses, or even in cement plants. Wherever the product carrying rolls are exposed to contaminants, the surface of the rolls or rolls may be polished or ground with the polishing apparatus 100 of the present invention.
