Description

Aus der DE 196 11 734 A1 ist ein Verfahren zur Herstellung von Kronen und Brücken aus Spinell, Aluminia, Zirconia usw. bekannt, bei dem auf einen Einzelstumpf als erste Maßnahme des Verfahrens eine Folie tiefgezogen wird. Da bei diesem Verfahren eine genaue Modellabformung erwünscht ist, sind die üblichen Tiefziehvorrichtungen nicht brauchbar, da sie unweigerlich Falten in der tiefgezogenen Folie bilden. Eine bekannte Tiefziehvorrichtung ist mit allen Details in der DE 195 11 064 A1 beschrieben.DE 196 11 734 A1 describes a method for producing crowns and Bridges made of spinel, aluminia, zirconia, etc. known, on one Single die as a first measure of the process, a film is deep-drawn. There In this process, an accurate model impression is desired conventional thermoforming devices not usable, since they inevitably fold in the form deep-drawn film. A well-known deep-drawing device is with all Details described in DE 195 11 064 A1.

Es ist daher Aufgabe des in Anspruch 1 angegebenen Verfahrens und der im Anspruch 2 angegebenen Vorrichtung einen Einzelstumpf faltenfrei mit einer Folie zu überziehen.It is therefore an object of the method specified in claim 1 and the Claim 2 specified device with a single stump wrinkle-free Cover film.

Vorteilhafte Ausführungen der Vorrichtung sind in den Unteransprüchen 3 und 4 beschrieben.Advantageous embodiments of the device are in subclaims 3 and 4 described.

Die Erfindung wird anhand der einzigen Figur erläutert.The invention is explained with reference to the single figure.

Aus der Figur ist der Grundaufbau einer Tiefziehvorrichtungen erkennbar. Eine Folie 1 wird durch eine Einspannvorrichtung 2 gehalten. Da die Folie 1 nach dem Erhitzen aufgrund ihrer geringen Masse schnell die Wärme verliert, sind üblicherweise (nicht gezeigte) Wärmespeicherelemente vorgesehen. In einem Granulataufnahmeraum 6, der durch eine Wandung 5 gebildet wird, befindet sich das Granulat zum Halten des Objektes, hier des Einzelstumpfes 8. Im Boden des Aufnahmeraumes 6 ist ein Filter 7 vorgesehen, das verhindert, daß das Granulat durch das Vakuum unterhalb des Filters abgesaugt wird.The basic structure of a deep-drawing device can be seen from the figure. A film 1 is held by a clamping device 2 . Since the film 1 quickly loses heat after heating due to its low mass, heat storage elements (not shown) are usually provided. The granulate for holding the object, here the individual stump 8 , is located in a granule receiving space 6 , which is formed by a wall 5 . A filter 7 is provided in the bottom of the receiving space 6 , which prevents the granules from being sucked off by the vacuum below the filter.

Die erhitze Folie 1 wird auf die Dichtlippe 9 aufgelegt und tiefgezogen. Hierbei ummantelt sie den Einzelstumpf 8.The heated film 1 is placed on the sealing lip 9 and deep-drawn. Here it encases the single die 8 .

Für die gewünschte Präzision ist eine solche Vorrichtung aber noch nicht geeignet. Zum einen wird bei dem vorstehend erwähnten Verfahren eine sehr dünne Folie benötigt. Ihre Stärken betragen 0,1 mm oder dünner für die Beschichtung von Einzelstümpfen für die Schlickertechnik und höchstens 0,6 mm für die Teleskop-Kronentechnik. Solche Folien zerreißen unweigerlich in den herkömmlichen Tiefziehvorrichtungen. However, such a device is not yet for the desired precision suitable. Firstly, in the above-mentioned method, a very thin film needed. Their thicknesses are 0.1 mm or thinner for that Coating of individual dies for the slip technique and a maximum of 0.6 mm for the telescopic crown technique. Such films inevitably tear in the conventional deep-drawing devices.  

Durch den Einsatz des Trichters 4 mit einer Dichtlippe 3 am oberen Rand wird in überraschender Weise das Reißen der Folie 1 verhindert und ein faltenfreier Überzug auf dem Einzelstumpf 8 erzielt, da der Trichter 4 beim Tiefziehen die Folie 1 definiert auf den Stumpf 8 leitet, wodurch eine gleichmäßige Materialstärke auf dem Stumpf 8 erreicht wird.Through the use of the hopper 4 with a sealing lip 3 at the top of the tearing of the film 1 is in a surprising manner prevents and scored a wrinkle-free coating on the single die 8, as the hopper 4 in deep drawing the film 1 defines passes on the die 8, whereby a uniform material thickness is achieved on the stump 8 .

Ein weiteres Problem bei dünnen Folien kam durch das Granulat entstehen, das üblicherweise aus Blei in zylinderischer Form mit einem Durchmesser von etwa 0,5 mm besteht.Another problem with thin films came from the granules that usually made of lead in a cylindrical shape with a diameter of about 0.5 mm.

Es wurde nun gefunden, daß sich Messingkügelchen mit einem Durchmesser von 0,2 bis 0,5 mm, vorzugsweise 0.3 mm, besonders eignen, da sie die Folie 1 nicht perforieren.It has now been found that brass balls with a diameter of 0.2 to 0.5 mm, preferably 0.3 mm, are particularly suitable since they do not perforate the film 1 .
