Description
Die Erfindung betrifft ein System aus einer Vorrichtung zum Umformen und einem Schalttellerautomaten mit einer Werkzeugaufnahme zur Aufnahme von mindestens einem Umformwerkzeug, die zwischen zwei Einheitenträgern in einem Schalttellerautomaten angeordnet ist.The invention relates to a system of a device for forming and a switch plate machine with a tool holder for receiving at least one forming tool, which is arranged between two unit carriers in a switch plate machine.
Die Werkzeugaufnahme ist zum Umformen einenends mit einer hydraulischen Einrichtung zur Erzeugung eines Umformdrucks und anderenends mit einer hydraulischen Auswerfeinrichtung verbunden. Bei einem Werkzeugwechsel muss die Werkzeugaufnahme sowohl von der Hydraulik- als auch von der Auswerfeinrichtung demontiert werden. Nach dem die Werkzeuge gewechselt wurden, muss die Werkzeugaufnahme wieder mit der Hydraulik- und der Auswerfeinrichtung verbunden werden. Der Montageaufwand ist beachtlich. Die Umrüstzeit beträgt mehrere Stunden. Die damit verbundene Betriebsunterbrechung ist somit sehr kostspielig. Die
Die Erfindung hat die Aufgabe, ein gattungsgemäßes System dahingehend zu verbessern, dass ein Werkzeugwechsel zukünftig deutlich schneller und somit wirtschaftlicher als bisher erfolgen kann.The invention has the object to improve a generic system to the effect that a tool change in the future much faster and therefore more economical than before.
Die Erfindung löst die gestellte Aufgabe mit einer Vorrichtung der eingangs genannten Art, bei der erfindungsgemäß die Werkzeugaufnahme verschwenkbar zwischen den Einheitenträgern gelagert ist. Die Werkzeugaufnahme kann somit für einen Werkzeugwechsel einfach verschwenkt werden, so dass sie zum Wechseln der Werkzeuge leicht zugänglich ist. Die Werkzeuge können dann mit wenigen Handgriffen aus der Werkzeugaufnahme entnommen und anschließend durch andere ersetzt werden. Nachdem die Werkzeuge wieder in die Werkzeugaufnahme eingebaut worden sind, wird die Werkzeugaufnahme in ihre Betriebsstellung zurückverschwenkt. Ein Schalttellerautomat, in den die erfindungsgemäße Vorrichtung mit der Werkzeugaufnahme montiert ist, kann dann sofort wieder seinen Betrieb aufnehmen. Die Umrüstzeit beträgt höchstens 30 Minuten. Entsprechend gering ist die mit dem Werkzeugwechsel verbundene Betriebsunterbrechung. Durch die Verschwenkbarkeit der Werkzeugaufnahme ist der mit der Vorrichtung ausgerüstete Schalttellerautomat wirtschaftlich profitabel. Die zu wechselnden Werkzeuge sind in der Regel ein Umformstempel, eine Stempelhülse, eine Zwischenhülse, eine Matrize bzw. ein Matrizenpaket mit einem Ausstoßer.The invention solves this problem with a device of the type mentioned, in which according to the invention the tool holder is pivotally mounted between the unit carriers. The tool holder can thus be easily pivoted for a tool change, so that it is easily accessible for changing the tools. The tools can then be removed in a few steps from the tool holder and then replaced by others. After the tools have been re-installed in the tool holder, the tool holder is pivoted back into its operating position. A switch panel, in which the device according to the invention is mounted with the tool holder, can then immediately resume its operation. The changeover time is a maximum of 30 minutes. The operating interruption associated with the tool change is correspondingly low. Due to the pivotability of the tool holder of the equipped with the device indexer table is economically profitable. The tools to be changed are usually a forming die, a punch sleeve, an intermediate sleeve, a die or a die package with a pusher.
In den Einheitenträgern können Adapter angeordnet sein. Die Adapter verbinden die Werkzeugaufnahme einenends mit einer Hydraulikeinrichtung und anderenends mit einer Auswerfeinrichtung. Die Adapter können als lösbare Verbindungselemente zwischen der Hydraulikeinrichtung und der Werkzeugaufnahme und zwischen der Auswerfeinrichtung und der Werkzeugaufnahme ausgebildet sein. Die Werkzeugaufnahme kann mit Verschraubungen an den Adaptern befestigt werden. Vor dem Verschwenken der Werkzeugaufnahme werden die Verschraubungen gelöst. Dies kann in wenigen Minuten geschehen. Anschließend kann die Werkzeugaufnahme sofort in ihre Position für den Werkzeugwechsel verschwenkt werden. Ein bevorzugter Verschwenkwinkel kann bei ungefähr 120° liegen. Nach dem Zurückverschwenken der Werkzeugaufnahme wird die Werkzeugaufnahme wieder mit den Adaptern verschraubt.Adapters may be arranged in the unit carriers. The adapters connect the tool holder at one end to a hydraulic device and at the other end to an ejector. The adapters can be used as detachable connection elements be formed between the hydraulic device and the tool holder and between the ejector and the tool holder. The tool holder can be attached to the adapters with screwed connections. Before the pivoting of the tool holder, the glands are loosened. This can be done in a few minutes. Subsequently, the tool holder can be immediately pivoted to its position for the tool change. A preferred pivoting angle may be about 120 °. After swiveling back the tool holder, the tool holder is screwed back to the adapters.
Der auf der Seite der Auswerfeinrichtung angeordnete Adapter kann mit einem Führungszylinder, in dem die Auswerfeinrichtung geführt wird, bestückt sein.The arranged on the side of the ejector adapter can be equipped with a guide cylinder in which the ejection device is guided.
Die Adapter können Aufnahmeelemente zur Aufnahme der Endbereiche der Werkzeugaufnahme aufweisen. Die Aufnahmeelemente können als Halbzylinder, die in axialer Richtung halbierten Zylindern entsprechen, ausgebildet sein. Die Adapter und die Aufnahmeelemente sind vorzugsweise einstückig ausgebildet. Die Adapter können an ihrer Stirnseite Ränder aufweisen. Ferner können die Adapter an ihrer Stirnseite mit Anlageflächen versehen sein, an denen die Werkzeugaufnahme anliegen kann. Die Aufnahmeelemente können somit zwischen den Rändern und den Anlageflächen als Nuten ausgebildete Vertiefungen aufweisen. Beim Zurückverschwenken greift die Werkzeugaufnahme mit ihren Endbereichen in die Nuten ein, so dass die Adapter die Endbereiche teilweise umfassen.The adapters may have receiving elements for receiving the end regions of the tool holder. The receiving elements may be formed as half cylinders which correspond to cylinders which are halved in the axial direction. The adapters and the receiving elements are preferably formed in one piece. The adapters may have edges on their front side. Furthermore, the adapter can be provided on its front side with contact surfaces on which the tool holder can rest. The receiving elements can thus have recesses formed between the edges and the contact surfaces as grooves. When pivoting back the tool holder engages with their end portions in the grooves, so that the adapter partially surround the end portions.
In einer bevorzugten Ausführungsform können die Adapter Ränder mit Innenkonussen aufweisen. Die Endbereiche der Werkzeugaufnahme können hingegen mit Außenkonussen versehen sein. Beim Zurückverschwenken der Werkzeugaufnahme in ihre Betriebsstellung gleiten die Außenkonusse der Werkzeugaufnahme und die Innenkonusse der Adapter aufeinander ab. Dadurch wird die Werkzeugaufnahme an die Anlageflächen der Adapter gedrückt. Außerdem wird die Werkzeugaufnahme durch die als Halbzylinder ausgebildeten Aufnahmeelemente gegenüber den Adaptern zentriert.In a preferred embodiment, the adapters may have edges with internal cones. The end areas of the Tool holder, however, may be provided with outer cones. When swiveling the tool holder back into its operating position, the outer cones of the tool holder and the inner cones of the adapter slide off one another. As a result, the tool holder is pressed against the contact surfaces of the adapter. In addition, the tool holder is centered by the trained as a half-cylinder receiving elements relative to the adapters.
Die Anlageflächen der Adapter sorgen dafür, dass die Stirnseiten der Werkzeugaufnahme im Betrieb fest an den Adaptern anliegen. Die Anlageflächen können gegenüber den Rändern der Adapter zurückversetzt sein, so dass die Ränder der Adapter über die Anlageflächen hinausstehen.The contact surfaces of the adapters ensure that the end faces of the tool holder rest firmly against the adapters during operation. The abutment surfaces may be recessed relative to the edges of the adapters so that the edges of the adapters protrude beyond the abutment surfaces.
Außerdem können die Adapter jeweils einen Schaft, der in die Einheitenträger eingeführt ist, aufweisen. Auf diese Weise wird eine möglichst steife Verbindung zwischen den Einheitenträgern und den Adaptern hergestellt. Verschraubungen, die zur Befestigung der Adapter mit den Einheitenträgern dienen können, werden somit von Querkräften entlastet.In addition, the adapters may each have a shaft inserted into the unit carrier. In this way a stiff connection between the unit carriers and the adapters is made. Fittings that can serve to attach the adapter with the unit carriers are thus relieved of lateral forces.
In einer Weiterbildung der Erfindung kann der Schaft einer der Adapter von einer im Einheitenträger angeordneten Manschette umfasst sein. Die Manschette kann vorzugsweise aus einem Elastomer gefertigt sein. Durch die Manschette ist der Adapter im Einheitenträger schwimmend gelagert. Er kann sich im Einheitenträger sowohl in axialer Richtung als auch in radialer Richtung bewegen. Der Bewegungsspielraum, der im zehntel Millimeterbereich liegt, kann zweckmäßig sein, wenn sich die Werkzeugaufnahme während des Umformvorganges ebenfalls im zehntel Millimeterbereich aufbiegt. Auf diese Weise werden der Schaft und der Einheitenträger entlastet.In one development of the invention, the shaft of one of the adapters may be encompassed by a collar arranged in the unit carrier. The collar may preferably be made of an elastomer. Through the cuff, the adapter is floating in the unit carrier. He can move in the unit carrier both in the axial direction and in the radial direction. The range of motion, which is in the tenth of a millimeter range, may be useful if the tool holder during the forming process also bends in tenths of a millimeter. In this way, the shaft and the unit carrier are relieved.
Um die Werkzeugaufnahme verschwenken zu können, kann sie an ihren Endbereichen mit Schwenkhebeln verschwenkbar gelagert sein. Die Schwenkhebel können in den Einheitenträgern mittels Schwenkbolzen gelagert sein. Die Schwenkbolzen können somit die Schwenkachse der Schwenkhebel und der Werkzeugaufnahme bilden.In order to pivot the tool holder, it may be pivotally mounted at its end with pivoting levers. The pivot levers can be mounted in the unit carriers by means of pivot pins. The pivot pin can thus form the pivot axis of the pivot lever and the tool holder.
Die Schwenkhebel können eine Nut zur Aufnahme der Endbereiche der Werkzeugaufnahme aufweisen. Die Schwenkhebel können in dem Bereich, indem sie die Werkzeugaufnahme teilweise umfassen, ebenfalls wie Halbzylinder ausgebildet sein.The pivot levers may have a groove for receiving the end portions of the tool holder. The pivot levers may also be formed as half cylinders in the region by partially enclosing the tool holder.
Einer der Schwenkhebel kann an seiner dem Einheitenträger zugewandten Stirnseite einen über diese vorstehenden Absatz aufweisen. Der Absatz kann in eine entsprechend ausgebildete Nut formschlüssig eingreifen, die vorzugsweise in dem Adapter angeordnet ist, der sich auf der Seite der Auswerfeinrichtung befindet. Auf diese Weise müssen Verschraubungen zur Befestigung des Schwenkhebels mit dem Adapter in der Betriebsstellung der Werkzeugaufnahme keine während ihres Aufbiegens entstehenden Querkräfte aufnehmen.One of the pivot levers may have on its front side facing the unit carrier on this projecting paragraph. The shoulder can engage positively in a correspondingly formed groove, which is preferably arranged in the adapter, which is located on the side of the ejection device. In this way, fittings for mounting the pivot lever with the adapter in the operating position of the tool holder do not absorb any transverse forces arising during their bending.
Zweckmäßigerweise kann die Werkzeugaufnahme mit einer Schwenkwelle verschwenkt werden. Die Schwenkwelle kann mit einem Elektromotor oder hydraulisch angetrieben werden. Der Elektromotor kann auf den bevorzugten Verschwenkwinkel von circa 120° eingestellt werden.Appropriately, the tool holder can be pivoted with a pivot shaft. The pivot shaft can be driven by an electric motor or hydraulically. The electric motor can be adjusted to the preferred pivot angle of about 120 °.
Um den Werkzeugwechsel zu erleichtern, kann einer der Einheitenträger mit einer Ausnehmung zum erleichterten Entfernen und Zuführen der Werkzeuge versehen sein.To facilitate the tool change, one of the unit carriers may be provided with a recess for facilitated removal and feeding of the tools.
Nachfolgend wird ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung anhand der beiliegenden Zeichnungen näher erläutert.Hereinafter, an embodiment of the device according to the invention will be explained in more detail with reference to the accompanying drawings.
