Bei einem solchen Werkzeug muss das Volumen des Rohlings weitgehend genau mit dem Innenvolumen des Werkzeugs übereinstimmen.at Such a tool must largely the volume of the blank exactly match the internal volume of the tool.
Aufgabenstellungtask
Es ist Aufgabe der vorliegenden Erfindung, eine Umformvorrichtung zu schaffen, bei der die Füllung der Form zuverlässig funktioniert.It Object of the present invention, a forming device to create at the filling the form reliable works.
Die Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. Hierbei ist von Vorteil, daß die Schließkraft mittels der zwei Schließvorrichtungen, die unterschiedliche Schließkräfte aufweisen, an den benötigten Preßkraftverlauf, der für eine komplette Formfüllung des Werkzeugs notwendig ist, anpassbar ist.The The object is achieved by the The subject of claim 1 solved. It is advantageous that the closing force by means of the two closing devices, have different closing forces, at the required Preßkraftverlauf, the for a complete mold filling of the tool is necessary, is customizable.
Erfindungsgemäß ist in einer anderen Weiterbildung vorgesehen, daß die Vorrichtung wenigstens einen Stempel aufweist. Diese Stempel erweisen sich unter anderem als vorteilhaft im Falle des Auswerfens des fertigen Teiles aus dem Werkzeug.According to the invention is in another development provided that the device at least has a stamp. These stamps prove, among other things as advantageous in the case of ejection of the finished part the tool.
Es erweist sich als vorteilhaft, daß durch die Verwendung von unterschiedlichen Speichern unterschiedliche Schließkräfte realisierbar sind.It proves to be advantageous that by the use of different storage different closing forces feasible are.
In einer anderen erfindungsgemäßen Weiterbildung ist vorgesehen, daß die Vorrichtung einen Gegenstempel aufweist.In another embodiment of the invention is provided that the Device has a counter punch.
Eine erfindungsgemäße Weiterbildung der Erfindung sieht vor, daß die Vorrichtung wenigstens einen Auswerferstift aufweist.A inventive development the invention provides that the Device has at least one ejector pin.
Die Aufgabe wird erfindungsgemäß mittels einer Presse zum Umformen gelöst, die eine eingangs beschriebene Vorrichtung zum Umformen auf weist.The The object is achieved by means of a Solved press for forming, having an initially described device for forming on.
In einer erfindungsgemäßen Weiterbildung ist vorgesehen, daß die Presse wenigstens einen Stößel und wenigstens einen Pressentisch aufweist.In a development of the invention is provided that the Press at least a pestle and has at least one press table.
Eine andere erfindungsgemäße Weiterbildung sieht vor, daß die Presse wenigstens einen Stößelauswerferbolzen und wenigstens einen Tischauswerferbolzen aufweist.A other training according to the invention provides that the Press at least one plunger ejector pin and at least one Tischauswerferbolzen.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren zum Umformen gelöst, wobei eine Vorrichtung und/oder eine Presse zum Umformen, wie weiter oben beschrieben, zum Einsatz kommen. Von Vorteil ist hierbei, daß mittels dieses Verfahrens hergestellte Teile wegen der kompletten Formfüllung des Werkzeuges sehr präzise gefertigt werden.The object is achieved by a method for forming, wherein a device and / or a press for forming, as described above, are used. The advantage here is that forth by means of this method Asked parts are made very precisely because of the complete mold filling of the tool.
