Description

Die Erfindung betrifft eine Maschine zur Bandschleifbearbeitung von Werkstückoberflächen eines Werkstücks, mit einer Aufnahmevorrichtung für ein umlaufendes Schleifband.The invention relates to a machine for Belt grinding of workpiece surfaces of a Workpiece, with a receiving device for a revolving sanding belt.

Mit den bekannten Maschinen zur Bandschleifbearbeitung von Werkstücken können im Maschinenbau übliche, gute Oberflächenqualitäten erzielt werden. Jedoch besteht der Bedarf, die Oberflächenqualität von Werkstücken weiter verbessern zu können und die Bearbeitungszeiten zur Oberflächenbearbeitung zu verringern. With the known machines for belt grinding of Workpieces can be used in mechanical engineering as usual Surface qualities are achieved. However, there is the Need to continue the surface quality of workpieces to be able to improve and the processing times for Reduce surface finish.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Maschine zur Bandschleifbearbeitung von Werkstückoberflächen eines Werkstücks zu schaffen, mit der höchste Oberflächenqualitäten bei kurzen Bearbeitungsdauern ermöglicht sind.On this basis, the present invention is the Task based, a machine for belt grinding of workpiece surfaces to create a workpiece, with the highest surface qualities in short Processing times are possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Aufnahmevorrichtung und/oder das Werkstück bewegbar ist zur Erzeugung einer in der Werkstückoberfläche auszubildenden Kreuzschliffstruktur.This object is achieved in that the Receiving device and / or the workpiece is movable to Generation of a trainee in the workpiece surface Cross hatch structure.

Hierdurch können Oberflächenqualitäten erzeugt werden, die höchsten Ansprüchen genügen. Eine Verbesserung der Oberflächenqualität wird sowohl bei Verwendung von schleifend wirkenden Schleifbändern als auch bei Verwendung von finishend wirkenden Schleifbändern erzielt. Letztere können auch als Finishband bezeichnet werden.As a result, surface qualities can be generated, the meet the highest standards. An improvement in the Surface quality is both when using abrasive grinding belts as well as in use achieved by finishend acting abrasive belts. Latter can also be referred to as finishing tape.

Die Erfindung betrifft insbesondere eine Maschine zur Bandschleifbearbeitung von Werkstückoberflächen eines Werkstücks, mit einer Aufnahmevorrichtung für ein umlaufendes Schleifband, wobei die Aufnahmevorrichtung entlang eines gradlinigen Verfahrweg parallel zu einer zu bearbeitenden Werkstückoberfläche verfahrbar ist.The invention particularly relates to a machine for Belt grinding of workpiece surfaces of a Workpiece, with a receiving device for a revolving abrasive belt, wherein the receiving device along a straight line parallel to one to machinable workpiece surface is movable.

Derartige Maschinen werden bevorzugt für längliche Werkstücke wie Achsen oder Walzen eingesetzt. Um die Werkstücke entlang ihrer gesamten Länge bearbeiten zu können, wird das Schleifband parallel zu einer zu bearbeitenden Werkstückoberfläche verfahren. Das Schleifband ist in einer Aufnahmevorrichtung aufgenommen, in oder an der das Schleifband geführt ist. Die Aufnahmevorrichtung wird auch als "Kassette" bezeichnet. Unter Aufnahmevorrichtung soll hier jedes zur Lagerung eines umlaufenden Schleifbands geeignete Trägerteil verstanden werden.Such machines are preferred for elongated Workpieces such as axles or rollers used. To the Workpieces along their entire length to edit can, the abrasive belt is parallel to one too process the workpiece surface. The Abrasive belt is received in a receiving device, in or on which the sanding belt is guided. The Recording device is also referred to as "cassette". Under recording device should here each for storage a circulating abrasive belt suitable carrier part be understood.

Die der Erfindung zugrunde liegende Aufgabe wird erfindungsgemäß auch dadurch gelöst, dass die Aufnahmevorrichtung und das Schleifband um eine zum Verfahrweg im Wesentlichen senkrecht angeordnete Achse verschwenkbar sind.The object underlying the invention is According to the invention also solved in that the Receiving device and the sanding belt to a for Travel essentially vertical axis are pivotable.

Durch die Verschwenkbarkeit des Schleifbands relativ zu der zu bearbeitenden Werkstückoberfläche kann das umlaufende Schleifband verschiedene Lagen relativ zum Verfahrweg des Schleifbands einnehmen. Zwischen Laufrichtung des Schleifbands und dem Verfahrweg des Schleifbands kann ein Winkel eingeschlossen sein, der so einstellbar ist, dass er von einem rechten Winkel abweicht. Hierdurch kann die Fläche, mit der das Schleifband an dem zu bearbeitenden Werkstück anliegt, beeinflusst und außerdem eine für viele Anwendungsfälle gewünschte Kreuzschliffstruktur erzeugt werden. Hierauf wird später noch detaillierter Bezug genommen.By the pivotability of the abrasive belt relative to the To be machined workpiece surface, the circumferential Abrasive belt different positions relative to the travel of the Take up grinding belts. Between running direction of the Abrasive belts and the path of the abrasive belt can a Be included angle that is adjustable so that he deviates from a right angle. This allows the Surface with which the sanding belt to be processed Workpiece abuts, influences and also one for many Applications generated desired cross-section structure become. This will be referred to later in more detail taken.

Besonders gute Oberflächenqualitäten können erzielt werden, wenn die Bandschleifbearbeitung durch Einstellung des Anstellwinkels des Schleifbands und/oder der Bewegungsgeschwindigkeit der Aufnahmevorrichtung und/oder der Bewegungsgeschwindigkeit des Werkstücks und/oder der Umlaufgeschwindigkeit des Werkstücks beeinflussbar ist.Particularly good surface qualities can be achieved if the belt grinding processing by adjusting the Angle of the abrasive belt and / or the Movement speed of the recording device and / or the speed of movement of the workpiece and / or the Circulating speed of the workpiece can be influenced.

Besonders vorteilhaft ist es, wenn die Aufnahmevorrichtung und das Schleifband während der Bewegung entlang des Verfahrwegs verschwenkbar sind. Dies bedeutet, dass der Winkel zwischen Laufrichtung des Schleifbands und dem Verfahrweg während der Bewegung entlang des Verfahrwegs nicht konstant sein muss. Vielmehr können Laufrichtung des Schleifbands und Verfahrweg während der Bewegung entlang des Verfahrwegs unterschiedliche Winkel miteinander einschließen. Dies erlaubt eine besonders flexible Oberflächenbearbeitung von Werkstücken. Insbesondere bei Werkstücken, die nicht entlang ihrer gesamten Länge gleichmäßig bearbeitet werden, sondern beispielsweise in einem zentrischen Bereich ballig ausgebildet sein sollen, kann durch die Verschwenkbarkeit der Aufnahmevorrichtung und des Schleifbands während der Bewegung entlang des Verfahrwegs eine solche ungleichförmige Bearbeitung durchgeführt werden.It is particularly advantageous if the receiving device and the abrasive belt during movement along the Travels are pivotable. This means that the Angle between the direction of the abrasive belt and the Traverse while moving along the travel path does not have to be constant. Rather, the running direction of the Sanding belts and travel path while moving along the travel different angles with each other lock in. This allows a particularly flexible Surface machining of workpieces. Especially at Workpieces that are not along their entire length be processed evenly, but for example in should be formed crowned a centric area, can by the pivotability of the recording device and the sanding belt while moving along the Traversing such a non-uniform machining be performed.

Eine besonders vorteilhafte Ausführungsform der Erfindung sieht vor, dass ein Antrieb vorgesehen ist, mit dem das Werkstück rotierend antreibbar ist. Hierdurch kann der Relativbewegung zwischen Schleifband und Werkstück eine Rotationsbewegung des Werkstücks überlagert werden. Hierdurch können besonders gute Oberflächenqualitäten erzielt werden.A particularly advantageous embodiment of the invention provides that a drive is provided, with which the Workpiece is driven in rotation. This allows the Relative movement between the grinding belt and workpiece one Rotational movement of the workpiece are superimposed. This allows particularly good surface qualities be achieved.

Die Aufnahmevorrichtung kann mittels eines Schwenklagers schwenkbar gelagert sein. Dieses Lager ermöglicht es, das Schleifband in oder an seiner Aufnahmevorrichtung relativ zum zu bearbeitenden Werkstück zu orientieren. Vorzugsweise ist das Schwenklager aus einer Mittellage heraus in zueinander entgegengesetzte Schwenkrichtungen um die im Wesentlichen senkrecht zum Verfahrweg angeordnete Achse verschwenkbar. Es liegt jedoch auch im Rahmen der Erfindung, wenn die Aufnahmevorrichtung um 360° oder mehr drehbar ist. In diesem Fall könnte das Schwenklager auch als Drehlager bezeichnet werden. The receiving device can by means of a pivot bearing be mounted pivotally. This bearing allows the Sanding belt in or on its recording device relative to orient to the workpiece to be machined. Preferably is the pivot bearing out of a middle layer out in mutually opposite pivot directions about the in Essentially arranged perpendicular to the travel axis pivotable. However, it is also within the scope of Invention, when the recording device by 360 ° or more is rotatable. In this case, the pivot bearing could also be referred to as a pivot bearing.

Die Schwenkachse des Schwenklagers kann die Rotationsachse des Werkstücks schneiden oder windschief zu ihr verlaufen. Bei sich schneidender Anordnung von Schwenkachse und Rotationsachse kann das Schleifband um den Mittelpunkt der Kontaktfläche zum Werkstück verschwenkt werden, so dass die Einstellbarkeit des Schleifbands relativ zur Verfahrrichtung der Maschine um den Mittelpunkt der Kontaktfläche herum erfolgen kann. Bei windschiefer Anordnung von Schwenkachse und Rotationsachse kann das Schleifband beispielsweise an einem vom Werkstück entfernten Ort verschwenkt und danach in Kontaktlage mit. dem Werkstück gebracht werden.The pivot axis of the pivot bearing may be the axis of rotation of the workpiece or run obliquely to it. In intersecting arrangement of pivot axis and Rotation axis may be the abrasive belt around the center of the Contact surface are pivoted to the workpiece, so that the Adjustability of the abrasive belt relative to Travel direction of the machine around the center of the Contact surface can be done around. In wind schist Arrangement of pivot axis and rotation axis can the Grinding belt, for example, on one of the workpiece pivoted place and then in contact with. be brought to the workpiece.

Das Schwenklager kann in die Aufnahmevorrichtung integriert sein oder auch außerhalb der Aufnahmevorrichtung vorgesehen sein. Dies bedeutet, dass die Aufnahmevorrichtung mit dem Schleifband "um sich selbst herum" schwenkbar sein kann oder um eine Schwenkachse, um die die Aufnahmevorrichtung zusammen mit dem Schleifband in Form eines Bogens oder Bogenabschnitts schwenkbar ist.The pivot bearing can be integrated into the receiving device be provided or outside the recording device be. This means that the receiving device with the Sanding belt "around itself" can be swiveled or about a pivot axis about which the receiving device together with the sanding belt in the form of a bow or Arc section is pivotable.

Vorteilhafterweise ist ein Antrieb vorgesehen, mit dem die Aufnahmevorrichtung verschwenkbar ist. Hierdurch ist ein manueller Eingriff oder ein manuelles Einrichten für das Verschwenken der Aufnahmevorrichtung mit dem Schleifband nicht notwendig, und die Verschwenkung kann durch eine geeignete Ansteuerung des Antriebs durchgeführt werden. Selbstverständlich kann diese Ansteuerung auch erfolgen, während die Aufnahmevorrichtung und das Schleifband entlang des Verfahrwegs bewegt werden.Advantageously, a drive is provided, with which the Recording device is pivotable. This is a manual intervention or manual setup for the Swiveling the recording device with the sanding belt not necessary, and the pivoting can by a suitable control of the drive can be performed. Of course, this control can also be done while the cradle and the sanding belt go along of the travel are moved.

Die Aufnahmevorrichtung kann innerhalb eines Winkels von 180° stufenlos verstellbar sein. Somit kann der Winkel zwischen Laufrichtung des Schleifbands und Verfahrweg innerhalb des genannten Winkels beliebig eingestellt werden, so dass die Orientierung der Schleifspuren auf der Oberfläche des Werkstücks beliebig bestimmbar ist.The receiving device can within an angle of 180 ° infinitely adjustable. Thus, the angle between the direction of the sanding belt and travel set arbitrarily within said angle so that the orientation of the sanding marks on the Surface of the workpiece is arbitrarily determined.

Vorteilhafterweise ist der Winkel symmetrisch, bspw. um ± 45° zum Verfahrweg einstellbar. Jedoch kann die Aufnahmevorrichtung aus einer Mittellage heraus bspw. um bis zu 90° verschwenkt werden, so dass das Schleifband beliebig zum Werkstück anstellbar ist.Advantageously, the angle is symmetrical, eg. ± 45 ° adjustable to travel. However, the Recording device from a central position out, for example. To be pivoted up to 90 ° so that the sanding belt can be adjusted as desired to the workpiece.

Die Aufnahmevorrichtung kann ein Kontaktelement aufweisen, dass das Schleifband in Richtung auf die zu bearbeitende Werkstückoberfläche des Werkstücks drückt. Dieses Kontaktelement kann beispielsweise als Rolle oder Stempel ausgebildet sein und in sich in einem gewissen Maße nachgiebig sein. Das Kontaktelement kann auch starr ausgebildet sein.The receiving device may have a contact element, that the sanding belt towards the to be machined Workpiece surface of the workpiece presses. This Contact element, for example, as a roll or stamp be educated and to a certain extent be forgiving. The contact element can also be rigid be educated.

Das Kontaktelement kann auch an einer Wippe gelagert sein, so dass das Kontaktelement in seiner Lage relativ zur zu bearbeitenden Werkstückoberfläche einstellbar und/oder anpassbar ist. Es ist auch möglich, über Kontaktelement und Wippe Tast- und/oder Schaltelemente zu betätigen, so dass beispielsweise eine Erfassung des Durchmessers des zu bearbeitenden Werkstücks möglich ist.The contact element can also be mounted on a rocker, so that the contact element in its position relative to editable workpiece surface adjustable and / or is customizable. It is also possible via contact element and Rocker tactile and / or switching elements to operate, so that For example, a detection of the diameter of the machining workpiece is possible.

Vorteilhafterweise ist auch der Anpressdruck des Kontaktelements einstellbar. Der Anpressdruck kann hierdurch unabhängig von dem durch das Gewicht der Aufnahmevorrichtung bedingten Anpressdruck gewählt werden und die Rate, mit der Material von einer Werkstückoberfläche abgetragen wird, eingestellt werden. Die Einstellung des Anpressdrucks kann beispielsweise über pneumatisch und/oder hydraulisch betätigbare Zylinder erfolgen.Advantageously, the contact pressure of the Contact element adjustable. The contact pressure can independent of this by the weight of the Recording device conditional contact pressure can be selected and the rate at which material from one Workpiece surface is removed, can be adjusted. The adjustment of the contact pressure, for example, over pneumatically and / or hydraulically actuated cylinders respectively.

Nach einer weiteren vorteilhaften Ausführungsform ist die Lage und/oder Position der Kontaktstelle von Schleifband und Werkstück einstellbar. Insbesondere ist es vorteilhaft, wenn die Aufnahmevorrichtung in Umfangsrichtung um eine Werkstückachse des Werkstücks herum positionierbar ist. Hierdurch kann das Werkstück aus verschiedenen Lagen der Aufnahmevorrichtung bearbeitet werden.According to a further advantageous embodiment, the Position and / or position of contact point of abrasive belt and workpiece adjustable. In particular, it is advantageous when the receiving device in the circumferential direction to a Workpiece axis of the workpiece is positioned around. This allows the workpiece from different layers of Recording device to be edited.

Die Erfindung betrifft auch ein Verfahren zum Betrieb einer Maschine zur Bandschleifbearbeitung von Werkstückoberflächen eines Werkstücks, wobei die Aufnahmevorrichtung entlang des Werkstücks verfahren wird, und wobei das Werkstück mittels des Schleifbandes bearbeitet wird.The invention also relates to a method for operating a Machine for belt grinding of Workpiece surfaces of a workpiece, wherein the Receiving device is moved along the workpiece, and wherein the workpiece by means of the abrasive belt is processed.

Erfindungsgemäß wird der Schwenkwinkel der Aufnahmevorrichtung entlang des Verfahrweges und/oder an den Endpunkten des Verfahrweges verändert. Bei Veränderung des Schwenkwinkels an den Endpunkten des Verfahrweges kann eine Kreuzschliffstruktur auf der Oberfläche des zu bearbeitenden Werkstücks erzeugt werden. Bei Änderung des Schwenkwinkels entlang des Verfahrwegs, d.h. zwischen den Endpunkten des Verfahrwegs, kann das Werkstück entlang seiner Länge verschiedenartig bearbeitet werden, so dass beispielsweise eine leicht ballig ausgebildete Walze herstellbar ist.According to the invention, the pivot angle of the Receiving device along the travel path and / or on changed the end points of the travel. In case of change the pivot angle at the end points of the travel can a cross-sectioned structure on the surface of the machining workpiece are generated. When changing the Swing angle along the travel, i. between End points of the travel, the workpiece can along its length can be processed differently, so that For example, a slightly convex roller can be produced.

Die erfindungsgemäße Maschine kann auch derart betrieben werden, dass in einem ersten Schritt die Aufnahmevorrichtung in einer ersten Richtung entlang des Werkstücks verfahren wird, in einem zweiten Schritt die Aufnahmevorrichtung in einer zur ersten Richtung entgegengesetzten zweiten Richtung verfahren wird, wobei während des ersten und des zweiten Schritts das Werkstück mittels des Schleifbands bearbeitet wird und die Schwenkwinkel der Aufnahmevorrichtung während des ersten und zweiten Schritts voneinander unterschiedlich eingestellt werden. Somit können auch Kreuzschliffstrukturen erzeugt werden, die nicht symmetrisch zur Längs- und/oder Rotationsachse des Werkstücks angeordnet sind. Die Bearbeitüngsspuren, die durch den genannten ersten Schritt erzeugt worden sind, können einen anderen Winkel mit der Längsrotationsachse des Werkstücks einschließen als die Bearbeitungsspuren, die während des genannten zweiten Schritts erzeugt worden sind.The machine according to the invention can also be operated in this way be that in a first step the Receiving device in a first direction along the Workpiece is moved, in a second step the Receiving device in a direction to the first opposite second direction is, wherein during the first and second steps, the workpiece is processed by means of the abrasive belt and the Pivoting angle of the receiving device during the first and second step from each other be set. Thus, too Cross-cut structures are generated that are not symmetrical to the longitudinal and / or rotational axis of Workpiece are arranged. The editing tracks, the generated by said first step, can have a different angle with the longitudinal axis of rotation of the Workpieces include as the machining marks, the have been generated during said second step.

Die genannten Verfahrbewegungen können auch in einer ersten Richtung oder in zwei zueinander entgegengesetzten Richtungen wiederholt werden, wobei jeweils unterschiedliche oder abwechselnd voneinander verschiedene Schwenkwinkel eingestellt werden können. Beispielsweise können Laufrichtung des Schleifbandes und Verfahrweg zunächst einen Winkel von 60°, dann einen Winkel von 30° und anschließend wieder einen Winkel von 60° zueinander einnehmen.The mentioned movements can also be in a first Direction or in two opposite directions Directions are repeated, respectively different or alternately different from each other Pivoting angle can be adjusted. For example can sense the direction of the sanding belt and travel path first an angle of 60 °, then an angle of 30 ° and then again an angle of 60 ° to each other taking.
