Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Bauteils mit einem Bund von einer vorbestimmten Wandstärke im Verhältnis zu der Blechdicke eines Stanzstreifens und einer bestimmten Höhe, einer Stirnkante und einer Innenform.The The invention relates to a method for producing a component with a collar of a predetermined wall thickness in relation to the sheet thickness of a Punching strip and a certain height, a front edge and a Interior shape.
Nach dem allgemeinen Wissen der betroffenen Fachkreise wird ein derartiges Bauteil bevorzugt so hergestellt, dass der Bund aus einem Blechstreifen ausgezogen und anschliessend die Stirnkante des Bundes bearbeitet wird. Hierbei kommt es häufig zu Rissen in dem Bund, so dass das Ausziehen sehr sorgfältig vorgenommen werden muss. Ferner ist der Wandstärke des Bundes im Verhältnis zur Blechdicke eine Grenze gesetzt. Diese Grenze liegt bei 0,5 bis 0,6 × Blechdicke.To The general knowledge of the experts concerned becomes such Component preferably made so that the collar of a sheet metal strip pulled out and then edited the front edge of the Federal becomes. This often happens to cracks in the waistband, so that taking off very carefully must become. Furthermore, the wall thickness of the federal government in relation to Sheet thickness set a limit. This limit is 0.5 to 0.6 × sheet thickness.
Weiterhin
geht aus der
Nachteilig hierbei ist, dass die Wandstärke des Bundes nach wie vor relativ gross ist, was gerade durch die Herstellung des doppelten Bundes hervorgerufen wird.adversely Here is that the wall thickness the federal government is still relatively large, which is precisely by the Producing the double federal is caused.
Aufgabe der vorliegenden Erfindung ist es, das oben beschriebene Bauteil in einem Stanzwerkzeug, insbesondere in einem Feinschneidwerkzeug herzustellen, wobei die Wandstärke des Bundes verringert sein soll, gleichzeitig aber die Rechtwinkligkeit der Stirnkante und ein Ausfüllen eines Einzugs erreicht wird.task The present invention is the component described above in a punching tool, in particular in a fineblanking tool produce, with the wall thickness the federal government should be reduced, but at the same time the squareness the front edge and a filling a collection is achieved.
LÖSUNG DER AUFGABESOLUTION OF THE TASK
Zur Lösung der Aufgabe führt ein Verfahren mit den Merkmalen des Patentanspruches 1.to solution the task leads a method having the features of claim 1.
Vorteilhafte Ausgestaltungen des Verfahrens sind Gegenstand der auf den Patentanspruch 1 rückbezogenen Unteransprüche.advantageous Embodiments of the method are the subject of the claim 1 back Dependent claims.
Durch dieses Verfahren wird es möglich, in einem Stanz- bzw. Feinschneidwerkzeug aus einem Stanzstreifen einen Bund herauszuformen, der eine Wandstärke von ≤ 0,175 × Blechdicke aufweist. Ferner wird durch das Zurückstauchen gewährleistet, dass die Stirnkante bei minimalstem Einzug rechtwinklig und plan verläuft. Des Weiteren treten, wie die Praxis gezeigt hat, keine Risse im Bund, insbesondere auch keine Haarrisse auf.By this method will make it possible in a punching or fine blanking tool from a punched strip to form a collar that has a wall thickness of ≤ 0.175 × sheet thickness. Further is by the dive back guaranteed that the front edge runs at right angles and flat with minimum feed. Of Furthermore, as practice has shown, there are no cracks in the collar, especially no hairline cracks.
In einem weiteren Ausführungsbeispiel der Erfindung soll der Schneidstempel mit einer Schneidbuchse zusammenwirken, welche sich gegen die Stirnkante des Bundes abstützt. Hierdurch bleibt die Ausgestaltung des Bundes auch beim Durchlochen der Innenform erhalten.In a further embodiment invention, the cutting punch is intended to cooperate with a cutting bush, which is supported against the front edge of the federal government. This leaves the design the federal also get the puncture of the inner shape.
In der letzten Stufe wird noch bevorzugt vorgesehen, dass in einem entsprechenden Ausschneidstempel zum Ausschneiden der Aussenform des Bauteils eine innere Abstützung geführt wird, so dass es auch hier bei einem endgültigen Ausschneiden des Bauteils aus dem Stanzstreifen nicht zu einem Eindrücken der Innenform kommt.In the last stage is still preferably provided that in a corresponding cut-out punch for cutting the outer shape the component an inner support guided so it will also be here at a final cut out of the component from the punching strip does not come to an impression of the inner mold.
