Abstract
Description
Die Erfindung bezieht sich auf ein Werkzeug mit direkter Betätigung, beispielsweise zum Stanzen, Biegen oder Ziehen von Blechen, bestehend aus einem Werkzeugunterteil mit Grundplatte und einer Schnitt-und/oder Formplatte, einem Führungsrahmen, einer Halteplatte zur Befestigung der Werkzeuge, wie Schnitt- und Formstempel, verbunden mit einer zu betätigenden Druckplatte, die in Ruhestellung außerhalb der Schnitt- bzw. Formplatte durch Elemente wie Federn oder Zylinder gehalten wird und einem Werkzeugoberteil mit einer Kopfplatte.The invention relates to a tool with direct actuation, for example for punching, bending or pulling sheet metal, consisting of a lower tool part with base plate and a cutting and / or molding plate, a guide frame, a holding plate for fastening the tools, such as cutting and Form stamp, connected to a pressure plate to be actuated, which is held in the rest position outside the cutting or form plate by elements such as springs or cylinders and an upper tool part with a head plate.
Es ist bereits bekannt, mechanisch betätigte Werkzeuge auf Pressen, insbesondere bei Einzel- und Kleinserienanfertigung, einzusetzen. Es hat sich hierbei gezeigt, daß Pressen dieser Art relativ aufwendig durch den fest zugeordneten Antriebszylinder sind, die mit ihrem Stößel auf das Werkzeug einwirken. Hierdurch ist es üblich, lediglich zweckgebundene Werkzeuge zu schaffen.It is already known to use mechanically actuated tools on presses, in particular for single and small series production. It has been shown here that presses of this type are relatively expensive due to the permanently assigned drive cylinder, which act on the tool with their ram. As a result, it is common to only create dedicated tools.
Die Aufgabe der Erfindung ist es, ein gattungsgemäßes Werkzeug zu schaffen, das einen Einsatz unabhängig vom Antriebszylinder ermöglicht und somit einen vielseitigen Einsatz gewährleistet.The object of the invention is to provide a generic tool that enables use independent of the drive cylinder and thus ensures a versatile use.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß zwischen Druckplatte und Kopfplatte ein folienartiges Trennelement zur abdichtenden Ausbildung getrennter Räume angeordnet ist und die Kopfplatte einen zum Trennelement führenden Druckanschluß aufweist, der mit einer Hydraulikversorgung bzw. einer pneumatischen Druckversorgung verbindbar ist.This object is achieved according to the invention in that a film-like separating element for the sealing formation of separate spaces is arranged between the pressure plate and the head plate and the head plate has a pressure connection leading to the separating element, which can be connected to a hydraulic supply or a pneumatic pressure supply.
Hierdurch ist es möglich, die Druckplatte direkt als Stempel für das Druckmedium einzusetzen und den Raum oberhalb des Trennelementes als entsprechend sich vergrößernden Raum mit Druckmittel zu füllen. Bei dieser erfindungsgemäßen Ausbildung ist eine relativ kleine Menge erforderlich, und weiterhin wird der Vorteil geschaffen, daß jedes Werkzeug in einer Taktstraße oder an jedem anderen Arbeitsplatz ohne gesonderte Presse einschaltbar ist.This makes it possible to use the printing plate directly as a stamp for the printing medium and to fill the space above the separating element with pressure medium as a correspondingly enlarging space. In this embodiment of the invention, a relatively small amount is required, and furthermore the advantage is created that each tool can be switched on in a cycle line or at any other work place without a separate press.
Eine einfache Ausbildung wird dadurch geschaffen, daß das Trennelement zwischen Kopfplatte und Führungsrahmen dichtend einspannbar ist.A simple design is created in that the separating element between the head plate and the guide frame can be clamped in a sealing manner.
Alternativ wird zum einfachen Austausch vorgeschlagen, daß das Trennelement an der Kopfplatte dichtend angeordnet ist.Alternatively, for simple replacement, it is proposed that the separating element be arranged in a sealing manner on the head plate.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung als Schnittdarstellung in Form eines Stanzwerkzeuges mit Lochstempel und Formstempel schematisch dargestellt.In the drawing, an embodiment of the invention is shown schematically as a sectional view in the form of a punching tool with punch and die.
Bei der dargestellten Anordnung ist ein Werkzeuguntergestell aus einer Grundplatte 1 mit einer Schnittplatte 2 gebildet, während das Werkzeugobergestell über einen Führungsrahmen 3 abgestützt wird und durch eine Kopfplatte 4 gebildet ist. Unterhalb der Kopfplatte ist eine vertikale bewegliche Druckplatte 5 mit einer Stempelhalteplatte 6 angeordnet. Die Stempelhalteplatte 6 trägt als Bearbeitungswerkzeuge in diesem Fall Lochstempel 7 und einen Formstempel 8. Zusätzlich ist eine Abstreiferplatte 9 über Federn 14 der Stempelhalteplatte 6 zugeordnet.In the arrangement shown, a tool base frame is formed from a base plate 1 with a
Zwischen den Bearbeitungswerkzeugen 7, 8 bzw. der Abstreiferplatte 9 ist ein Raum 10 für eine Werkstückaufnahme angeordnet, der eine Führungsleiste 11 für einen zu bearbeitenden Blechstreifen aufweist.Between the
Zur Betätigung der Druckplatte 5 ist die Kopfplatte 4 mit einer Bohrung 12 als Druckanschluß versehen, der mit einem Hydraulikaggregat verbunden wird. Über ein zwischen dem Führungsrahmen 3 und der Kopfplatte 4 eingespannten Trennelement 13 und einem folienartigen, flexiblen Material werden getrennte Räume geschaffen, so daß beim Zuführen von Hydraulikflüssigkeit über die Bohrung 12 sich der Raum zwischen Trennelement 13 und Kopfplatte 4 vergrößert und die Druckplatte 5 die Bearbeitungswerkzeuge 8, 9 über die Stempelhalteplatte 6 für den Bearbeitungsvorgang nach unten preßt.To actuate the
