Description
Die Erfindung betrifft eine Vorrichtung der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a device of the type specified in the preamble of
Die Greiferschienen einer Transferpresse sind in Greiferschienenteile aufgeteilt. Die im Pressenständerbereich befindlichen Greiferschienenteile verbleiben in der Presse; die Greifzeuge tragenden Greiferschienenteile werden dagegen gewechselt, wenn die Transferpresse auf ein anderes Werkstück eingerichtet wird.The gripper rails of a transfer press are divided into gripper rail parts. The gripper rail parts located in the press stand area remain in the press; on the other hand, the gripper rail parts carrying the grippers are replaced when the transfer press is set up on another workpiece.
Für den Pressenbetrieb, Transfer der Werkstücke in den Bearbeitungsstufen, sind die Greiferschienenteile untereinander zu (Gesamt-) Greiferschienen zu verbinden.For press operation and transfer of workpieces in the processing stages, the gripper rail parts are to be connected to one another to form (overall) gripper rails.
Die bisher bekannten Arten der Verbindungen der Greiferschienenteile untereinander sind sehr vielgestaltig, ohne daß jedoch Anregungen auf eine Lösung nach der Erfindung gegeben werden.The previously known types of connections of the gripper rail parts to one another are very varied, but without giving suggestions for a solution according to the invention.
So zeigt die DE-A1-23 59 912 Greiferschienenteile, deren Endbereiche stufig abgesetzt sind. Die Trennstelle zwischen den aneinander stoßenden Endbereichen werden durch ein korrespondierend zu der Form der Endbereiche ausgebildetes Verbindungsstück überbrückt. Nicht gezeigt ist die Art der Verspannung der Greiferschienenteile untereinander.DE-A1-23 59 912 shows gripper rail parts, the end regions of which are stepped. The separation point between the abutting end regions is bridged by a connecting piece which corresponds to the shape of the end regions. The type of bracing of the gripper rail parts with one another is not shown.
Das DE-GM 82 02 432 zeigt korrespondierend geformte, im Betrieb aufeinanderliegende Endbereiche von Greiferschienenteilen, die durch ein Schraubmittel untereinander verspannt werden.DE-GM 82 02 432 shows correspondingly shaped end regions of gripper rail parts which lie one on top of the other during operation and are clamped to one another by a screwing means.
In der DE-C1-31 50 508 wird ein Trennspalt zwischen den Greiferschienenteilen durch ein aufklappbares Greiferschienenschloß überbrückt, das an dem in der Presse verbleibenden Greiferschienenteil klappbar angebracht ist. Die Verbindung der Greiferschienenteile untereinander erfolgt durch Schraubmittel.In DE-C1-31 50 508, a separating gap between the gripper rail parts is bridged by a hinged gripper rail lock that is attached to the gripper rail part remaining in the press foldable is attached. The gripper rail parts are connected to one another by screwing means.
Die DE-A1-32 35 308 zeigt ein Stellmittel in einer Maßnahme zum Kuppeln und Entkuppeln, das in einen Greiferschienenteil eingebracht ist. Dieses dient zur Sicherung des durch korrespondierend geformte Endbereiche der Greiferschienenteile gebildeten Formschlusses nach dem Fügen.DE-A1-32 35 308 shows an adjusting means in a measure for coupling and uncoupling, which is introduced into a gripper rail part. This serves to secure the positive connection formed by correspondingly shaped end regions of the gripper rail parts after the joining.
Bei der Vorrichtung nach der DE-A1-35 20 343 wird zwischen den Greiferschienenteilen ein Trennspalt gebildet. Dieser ist vor dem Verspannen der Greiferschienenteile gegeneinander durch Druckstücke aufzufüllen. Das Einfügen der Druckstücke in den Trennspalt und das daran anschließende Verspannen der Greiferschienenteile gegeneinander wird durch ein Stellmittel erreicht, das in dem Endbereich eines Greiferschienenteils befestigt ist. Das Stellmittel weist einen Spannbolzen auf, der einerseits die Druckstücke bewegt. Andererseits ist der Spannbolzen mit einem Spannkopf hinter eine Spannfläche in dem anzuspannenden Greiferschienenteil legbar und durch Zurückziehen festsetzbar.In the device according to DE-A1-35 20 343, a separating gap is formed between the gripper rail parts. Before tightening the gripper rail parts against each other, this must be filled with thrust pieces. The insertion of the pressure pieces into the separating gap and the subsequent clamping of the gripper rail parts against one another is achieved by means of an adjusting means which is fastened in the end region of a gripper rail part. The actuating means has a clamping bolt which on the one hand moves the pressure pieces. On the other hand, the clamping bolt can be placed with a clamping head behind a clamping surface in the gripper rail part to be clamped and can be fixed by pulling it back.
Aus den Druckschriften DE-A1-36 36 010 und DE-A1 36 36 011 sind weiterhin Vorrichtungen zum Kuppeln und Entkuppeln von Greiferschienenteilen einer Transferpresse bekannt. Die hierfür erforderlichen Spannmittel sind in den Endbereichen der Greiferschienenteile angeordnet. Hierbei ist mit dem Spannbolzen ein Brückenteil mitgeführt, an dem zwei Zentrierbolzen befestigt sind zum Zentrieren der Greiferschienenteile untereinander und an dem weiterhin ein Führungsbolzen mitgeführt ist zum Verschieben eines beweglichen Schlittens an der Außenform des das Spannelement aufnehmenden Greiferschienenteils.From documents DE-A1-36 36 010 and DE-A1 36 36 011 devices for coupling and uncoupling gripper rail parts of a transfer press are also known. The clamping devices required for this are arranged in the end regions of the gripper rail parts. Here, a bridge part is carried along with the clamping bolt, on which two centering bolts are fastened for centering the gripper rail parts with one another and on which a guide bolt is also carried for moving a movable slide on the outer shape of the gripper rail part receiving the clamping element.
Alle diese Lösungen setzen eine Mehrteiligkeit der Greiferschienenteile in den Endbereichen voraus. Die Einzelteil-Montage muß direkt an den Endbereichen der Greiferschienenteile erfolgen und es sind weiterhin umfangreiche Bearbeitungen spanabhebender Art und Schweißvorgänge an den Greiferschienenteilen bei der Vor- bzw. Montage durchzuführen.All of these solutions require multiple parts of the gripper rail parts in the end areas. The individual parts must be mounted directly on the end areas of the gripper rail parts and extensive machining operations and welding operations on the gripper rail parts must continue to be carried out during the preassembly or assembly.
Ausgehend von der gattungsbildenden Einrichtung nach DE-A1-36 36 010 ist es Aufgabe der Erfindung, die Elemente für das Kuppeln und Entkuppeln von Greiferschienenteilen in eine Baueinheit zu integrieren, um die Ausbildung der Endbereiche der Greiferschienenteile und somit die Bearbeitung der Endbereiche und die Montage 'vor Ort' wesentlich zu vereinfachen. Die Baueinheit ist als ein Ganzes vormontierbar, lagerbar und transportierfähig und an den Greiferschienenteilen als Komplett-Teil festsetzbar und bildet für den Betriebszustand "Greiferschienenwechsel zugleich mit dem Werkzeugwechsel" die hierfür erforderliche Kuppelebene.Starting from the generic device according to DE-A1-36 36 010, it is an object of the invention to integrate the elements for coupling and uncoupling gripper rail parts into a structural unit in order to form the end regions of the gripper rail parts and thus significantly simplify the processing of the end areas and the assembly 'on site'. The unit can be preassembled as a whole, can be stored and transported, and can be attached to the gripper rail parts as a complete part and forms the required coupling level for the operating state "gripper rail change at the same time as the tool change".
Die Aufgabe ist gelöst durch die in den Ansprüchen 1 oder 2 gezeigten Ausführungsbeispiele.The object is achieved by the exemplary embodiments shown in
Hierbei sind in vorteilhafter Weise alle Spannmittel von einem teilbaren Gehäuse umgeben, das insgesamt für den Einbau montagefertig und als solches auch bei Ersatz austauschbar ist.In this case, all clamping means are advantageously surrounded by a divisible housing which is overall ready for installation for installation and as such can be replaced even when replaced.
Die Baueinheit kann in ihren Querschnittsmaßen den Querschnittsmaßen der Endbereiche der Greiferschienenteile entsprechen, so daß nur ohnehin erforderliche Bauteile für eine andere Verwendung überstehen. Die Baueinheit ist auch bei solchen Greiferschienen anwendbar, deren Greiferschienenteile aus Flachschienen-Material gefertigt sind. Bereits vorhandene Greiferschienen, auch solche mit zunächst anderer Kupplungsausführung, sind nachrüstbar. Die Baueinheit ist sowohl für Greiferschienensysteme, bei denen Trennfugen in den Kupplungsebenen erforderlich sind, insbesondere aber auch für trennfugenfreie Greiferschienensysteme einsetzbar, bei denen die Greiferschienenteile durch flanschmäßiges Aneinanderpressen der Stirnseiten in den Endbereichen zu kuppeln sind.The cross-sectional dimensions of the structural unit can correspond to the cross-sectional dimensions of the end regions of the gripper rail parts, so that only components that are required anyway survive for any other use. The assembly can also be used with gripper rails whose gripper rail parts are made from flat rail material. Existing gripper rails, including those with an initially different coupling version, can be retrofitted. The assembly can be used both for gripper rail systems, where joints are required in the coupling levels, and in particular for gripper rail systems without joints, in which the parts of the gripper rail are to be coupled in the end areas by flanging the end faces together.
