Abstract

The tool comprises two individual components, which can be connected one above the other. The upper component (A) is a connector for a compressed air supply, and the lower component is a cutting crown (B).A screw (C) with an axial bore (E) may be used to fasten the crown to the connector. Alternatively, the crown may have an external thread which can engage directly with a corresponding internal thread on the upper component. Crowns with different cutter diameters, but with the same standard connection for the upper component, may also be fitted.

Description

Die Erfindung betrifft ein Stanzwerkzeug für Kunststoffolien mit pneumatischem Auswurf.The invention relates to a punching tool for plastic films pneumatic ejection.

Bekannte Stanzwerkzeuge für Kunststoffolien bestehen aus einem Werkzeugteil mit einer Messerkrone und einem Druckluftan­ schluß. Der Nachteil dieser Lösung besteht darin, daß beim Werk­ zeugwechsel zunächst der Druckluftanschluß gelöst werden muß. Erst danach, in einem zweiten Arbeitsgang, kann das Werkzeug mit Messerkrone ausgebaut werden. Der Druckluftanschluß an allen Werkzeugteilen erhöht den Materialeinsatz bei der Werkzeugher­ stellung und führt durch die damit verbundene Größe zu erhöhtem Lagerbedarf.Known punching tools for plastic films consist of a Tool part with a knife crown and compressed air Enough. The disadvantage of this solution is that at work tool change the compressed air connection must first be disconnected. Only then, in a second step, can the tool be used Knife crown to be removed. The compressed air connection at all Tool parts increase the amount of material used by the tool maker position and leads to increased through the associated size Storage requirements.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Werkzeug zu entwickeln, das mit geringem Fertigungs- und Materialaufwand einen schnelleren Werkzeugwechsel ermöglicht.The present invention is therefore based on the object To develop tool with low manufacturing and Material expenditure enables a faster tool change.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Werk­ zeug aus zwei Teilen, aus einer Druckluftzuführungseinheit und der eigentlichen Messerkrone, ausgeführt wird. Das zweiteilige Werkzeug wird erfindungsgemäß so hergestellt, daß Druckluftan­ schluß (Oberteil) und Messerkrone (Unterteil) miteinander kraft­ schlüssig verbunden werden. Dies geschieht entweder durch eine Schraubverbindung (Fig. 1), wobei die Verbindungsschraube mit einer Bohrung versehen wird, um die Druckluft für den Auswurf zur Messerkrone zu leiten, oder Oberteil und Messerkrone werden mit Gewinde ausgeführt (Fig. 2), so daß Ober- und Unterteil direkt miteinander verschraubt werden können. Die Konstruktion ist so ausgeführt, daß auf eine Druckluftzuführungseinheit Messerkronen unterschiedlicher Durchmesser aufgesetzt werden können.According to the invention this object is achieved in that the tool is made of two parts, a compressed air supply unit and the actual knife crown. The two-part tool is manufactured according to the invention so that the compressed air connection (upper part) and the knife crown (lower part) are connected to one another in a force-fitting manner. This is done either by a screw connection ( Fig. 1), whereby the connecting screw is provided with a hole to direct the compressed air for ejection to the knife crown, or the upper part and the knife crown are threaded ( Fig. 2), so that the upper and bottom part can be screwed directly together. The design is such that knife crowns of different diameters can be placed on a compressed air supply unit.

Die Vorteile der erfindungsgemäßen Lösung bestehen darin, daß ein schneller Werkzeugwechsel möglich ist, da der Druckluftanschluß an der Stanzmaschine verbleibt. Darüber hinaus reduzieren sich die Werkzeugkosten, da bei Verschleiß der Messerkrone nur diese ausgewechselt werden muß.The advantages of the solution according to the invention are that a quick tool change is possible because of the compressed air connection remains on the punching machine. They also reduce themselves  the tool costs, as only the cutter crown wears out must be replaced.

Weitere Vorteile ergeben sich aus einer Verringerung des Lager­ volumens um den Anteil des Druckluftanschlusses.Further advantages result from a reduction in the stock volume by the proportion of the compressed air connection.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Werkzeuges näher erläutert.A preferred embodiment of a tool according to the invention explained in more detail.
