Abstract

The tool has a supporting half (1), in which the thin-walled insert (3) fits. The half has a negative shape taking account of the insert thickness and corresponding to the shape of the sheet-metal components (5) to be produced by deep-drawing. The insert is secured to the half by a number of detachable fasteners (6) engaging with its edge. These can consist of bolts welded to the insert and fitting in mating mountings in the half, to which they are screwed. Two sheet-metal components can be deep-drawn one above the other without using an insert, one forming the insert and the other a sheet-metal component.

Description

Die Erfindung betrifft ein Tiefziehwerkzeug mit einer Trägerformhälfte sowie mit einer in diese eingelegten dünnwandigen Formschale, die austauschbar ist, wobei die Trägerformhälfte unter Berücksichtigung der Formschalendicke eine den durch Tiefziehen herzustellenden Blechteilen entsprechende Negativform aufweist. Ein derartiges Tiefziehwerkzeug bildet zumindest internen Stand der Technik.The invention relates to a deep-drawing tool with a carrier mold half and with a thin-walled mold shell inserted therein, which is interchangeable, the carrier mold half having a negative shape corresponding to the sheet metal parts to be produced by deep-drawing, taking into account the mold shell thickness. Such a deep-drawing tool forms at least the internal state of the art.

Insbesondere für das Tiefziehen von Aluminium-Blechteilen kommen Tiefzieh-Werkzeuge zum Einsatz, deren Werkzeug-Oberfläche beschichtet ist, beispielsweise durch PVD. Die Beschichtung wird dabei dahingehend optimiert, daß über eine lange Werkzeug-Standzeit eine hohe Oberflächenqualität der tiefzuziehenden Blechteile erzielt wird. Insbesondere beim Tiefziehen von Aluminium werden nämlich durch die sog. Reibaufschweißung die Kantenbereiche in der Negativform des Tiefziehwerkzeuges besonders hoch beansprucht. Da jedoch auch die Beschichtung einem stetigen Verschleiß unterliegt, ist nach einer gewissen Einsatzdauer eines derartigen Tiefzieh-Werkzeuges eine Neubeschichtung erforderlich, was insbesondere bei Großwerkzeugen äußerst aufwendig ist. Eine Abhilfemaßnahme bestünde darin, anstelle der Beschichtung in die sog. Trägerformhälfte des Tiefziehwerkzeuges eine austauschbare Formschale einzulegen. Diese Formschale könnte relativ dünnwandig sein und vollflächig auf der in der Trägerformhälfte unter Berücksichtigung der Formschalendicke vorgesehenen Negativform, die im wesentlichen den durch Tiefziehen herzustellenden Blechteilen entspricht, aufliegen. Bei Verschleiß könnte diese Formschale dann einfach ausgetauscht werden.Deep-drawing tools whose tool surface is coated, for example by PVD, are used in particular for deep-drawing aluminum sheet metal parts. The coating is optimized so that a high surface quality of the deep-drawn sheet metal parts is achieved over a long tool life. In particular, when deep-drawing aluminum, the edge areas in the negative form of the deep-drawing tool are particularly stressed by the so-called friction welding. However, since the coating is also subject to constant wear, such is after a certain period of use Thermoforming tools require a new coating, which is extremely expensive, especially for large tools. A remedial measure would be to insert an exchangeable molded shell into the so-called carrier mold half of the deep-drawing tool instead of the coating. This molded shell could be relatively thin-walled and fully rest on the negative mold provided in the carrier mold half, taking into account the molded shell thickness, which essentially corresponds to the sheet metal parts to be produced by deep drawing. In the event of wear, this molded shell could then simply be replaced.

Grundsätzlich erscheint eine derartige Trägerformhälfte mit einer austauschbaren Formschale viele Vorteile zu besitzen, jedoch ist dafür Sorge zu tragen, daß diese Formschale einerseits unverrückbar an der Trägerformhälfte fixiert ist, um qualitativ hochwertige Tiefzieh-Blechteile formen zu können, daß jedoch andererseits diese Formschale auch wieder einfach von der Trägerformhälfte entfernt werden kann, wenn dies beispielsweise aufgrund von Verschleiß oder auch aufgrund anderer Gegebenheiten erwünscht ist.In principle, such a carrier mold half with an exchangeable mold shell appears to have many advantages, but care must be taken that this mold shell is fixed immovably on the carrier mold half in order to be able to form high-quality deep-drawn sheet metal parts, but that this mold shell is also simple again can be removed from the carrier mold half if this is desired, for example, due to wear or other circumstances.

Aufgabe der Erfindung ist es daher, an einem Tiefziehwerkzeug nach dem Oberbegriff des Anspruchs 1 Maßnahmen aufzuzeigen, mit Hilfe derer die eben genannten Anforderungen erfüllt werden. Zur Lösung dieser Aufgabe ist vorgesehen, daß die Formschale mit mehreren an deren Randbereich angreifenden, lösbaren Verbindungselementen an der Trägerformhälfte befestigt ist. Insbesondere können die Verbindungselemente als an die Formschale angeschweißte Bolzen ausgebildet sein, die in angepaßte Aufnahmen in der Trägerformhälfte einsetzbar und mit dieser verschraubbar sind.The object of the invention is therefore to demonstrate on a deep-drawing tool according to the preamble of claim 1 measures by means of which the requirements just mentioned are met. To achieve this object it is provided that the molded shell is fastened to the support mold half with a plurality of releasable connecting elements which engage at its edge region. In particular, the connecting elements can be designed as bolts welded to the molded shell, which can be inserted into adapted receptacles in the carrier mold half and screwed to the latter.

Eine Lösung der weiteren Aufgabe, ein vorteilhaftes Herstellverfahren für eine Formschale eines Tiefziehwerkzeuges nach dem Oberbegriff des Anspruchs 1 aufzuzeigen, ist im dritten Patentanspruch angegeben und besteht darin, daß in der Trägerformhälfte ohne eingelegte Formschale unter Mitwirkung der entsprechenden Gegenformhälfte übereinanderliegend zwei Bleche tiefgezogen werden, von denen eines die Formschale und das andere das im Tiefziehwerkzeug herzustellende Blechteil ergibt.A solution to the further object of demonstrating an advantageous manufacturing method for a molded shell of a deep-drawing tool according to the preamble of claim 1 is specified in the third claim and consists in that two sheets are deep-drawn one above the other in the carrier mold half without an inserted molded shell with the cooperation of the corresponding counter-mold half which one gives the molded shell and the other the sheet metal part to be produced in the deep-drawing tool.

Näher erläutert wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels, das in der beigefügten Prinzipskizze vereinfacht dargestellt ist. Dabei zeigt

Fig. 2
die Ansicht X aus Fig. 1.
The invention is explained in more detail with reference to a preferred exemplary embodiment, which is shown in simplified form in the attached schematic diagram. It shows
Fig. 1
a section through an inventive deep-drawing tool, and
Fig. 2
the view X from FIG. 1.

Mit der Bezugsziffer 1 ist eine Trägerformhälfte eines Tiefziehwerkzeuges bezeichnet, das eine im wesentlichen den durch Tiefziehen herzustellenden Blechteilen entsprechende Negativform 2 aufweist. Auf die Werkzeugoberfläche ist im Bereich der Negativform 2 sowie darüber hinausgehend und diesen Bereich dabei überlappend eine dünnwandige Formschale 3 aufgelegt.Reference number 1 denotes a carrier mold half of a deep-drawing tool which has a negative mold 2 which corresponds essentially to the sheet metal parts to be produced by deep-drawing. A thin-walled molded shell 3 is placed on the tool surface in the area of the negative mold 2 and beyond and overlapping this area.

Im übrigen ist auch die Negativform 2 der Trägerformhälfte 1 im Hinblick auf die eingelegte Formschale 3 ausgebildet, d. h. bei der Bemessung dieser Negativform 2 wird berücksichtigt, daß das nur bruchstückhaft dargestellte, unter Einsatz dieser Trägerformhälfte 1 durch Tiefziehen herzustellende Blechteil 5 nicht direkt auf der Trägerformhälfte 1, sondern auf der Formschale 3 aufliegt.Incidentally, the negative mold 2 of the carrier mold half 1 is also designed with regard to the inserted mold shell 3, ie when dimensioning this negative mold 2, it is taken into account that the fragmentary representation, to be produced using this carrier mold half 1 by deep drawing Sheet metal part 5 does not rest directly on the carrier mold half 1, but on the mold shell 3.

Für einen erfolgreichen Tiefziehvorgang des Blechteiles 5 muß die Formschale 3 einerseits sicher an der Trägerformhälfte 1 befestigt sein, andererseits ist es erwünscht, die Formschale 3 einfach austauschen zu können. Vorgesehen sind daher mehrere am Randbereich 4 der Formschale 3 angreifende Verbindungselemente 6, die lösbar entweder an der Formschale 3 oder an der Trägerformhälfte 1 befestigt sind. Im einzelnen bestehen diese Verbindungselemente 6, von denen in den Figuren lediglich ein einziges dargestellt ist, jeweils aus einem Bolzen 6a, der über den Rand der Formschale 3 hinausragend an dieser Formschale 3 angeschweißt ist. Dieser Bolzen 6a ist in eine angepaßte Aufnahme 6b in der Trägerformhälfte 1 eingesetzt und weist ein Durchgangsloch auf, das es ermöglicht, diesen Bolzen 6a mittels einer Schraube 6c an der Trägerformhälfte 1 festzuschrauben. Der Bolzen 6a bzw. die mehreren am Umfang der Formschale 3 angeordneten Bolzen 6a bzw. Verbindungselemente 6 dienen dabei nicht nur der Befestigung der Formschale 3 an der Trägerformhälfte 1, sondern stellen gleichzeitig deren exakte Positionierung sicher.For a successful deep-drawing process of the sheet metal part 5, the molded shell 3 must on the one hand be securely fastened to the carrier mold half 1, on the other hand, it is desirable to be able to easily replace the molded shell 3. There are therefore provided a plurality of connecting elements 6 which engage on the edge region 4 of the molded shell 3 and are detachably fastened either to the molded shell 3 or to the carrier mold half 1. Specifically, these connecting elements 6, of which only a single one is shown in the figures, each consist of a bolt 6a which is welded to this molded shell 3 so as to protrude beyond the edge of the molded shell 3. This bolt 6a is inserted into an adapted receptacle 6b in the carrier mold half 1 and has a through hole which makes it possible to screw this bolt 6a onto the carrier mold half 1 by means of a screw 6c. The bolt 6a or the plurality of bolts 6a or connecting elements 6 arranged on the circumference of the molded shell 3 not only serve to fasten the molded shell 3 to the carrier mold half 1, but at the same time ensure their exact positioning.

Nach Lösen der Verbindungselemente 6 kann die Formschale 3 aus der Trägerformhälfte 1 entnommen und gegen eine neue Formschale 3 ausgetauscht werden, die dann ebenfalls mit ihren Verbindungselementen 6 wieder in die Negativform 2 eingesetzt werden kann. Dabei kann dieser Austausch von Formschalen 3 nicht nur dann durchgeführt werden, wenn eine Formschale 3 relativ hohe Verschleißerscheinungen zeigt, sondern auch dann, wenn für spezielle Tiefziehprozesse unterschiedliche Werkzeug-Oberflächen benötigt werden. So können beispielsweise verschiedene Formschalen aus verschiedenen Materialien zum Einsatz kommen. Auch ist es mögich, Formschalen 3 unterschiedlicher Dicke vorzusehen, wodurch Blechteile 5 unterschiedlicher Dicke von im wesentlichen gleicher Form in der gezeigten Trägerformhälfte 1 bzw. dem entsprechenden Tiefziehwerkzeug geformt, d. h. tiefgezogen werden können.After loosening the connecting elements 6, the molded shell 3 can be removed from the carrier mold half 1 and exchanged for a new molded shell 3, which can then also be reinserted into the negative mold 2 with its connecting elements 6. This exchange of molded shells 3 can be carried out not only when a molded shell 3 shows relatively high signs of wear, but also when different tool surfaces are required for special deep-drawing processes. For example, different molded shells made of different materials can be used. It is also possible To provide molded shells 3 of different thicknesses, whereby sheet metal parts 5 of different thicknesses of essentially the same shape can be shaped, ie deep-drawn, in the shown carrier mold half 1 or the corresponding deep-drawing tool.

Das beschriebene Ausführungsbeispiel zeigt eine Trägerformhälfte in Form einer Matrize, wobei selbstverständlich eine entsprechend angepaßte Oberform/Patrize erforderlich ist, um das Blechteil 5 zu formen. Auch das Werkzeugoberteil, d. h. die Patrize kann mit einer entsprechenden Formschale versehen sein, es ist jedoch auch möglich, für das Werkzeugoberteil eine übliche Formhälfte ohne Formschale vorzusehen.The exemplary embodiment described shows a carrier mold half in the form of a die, a correspondingly adapted upper mold / patrix being of course required to form the sheet metal part 5. The upper part of the tool, i. H. the patrix can be provided with a corresponding molded shell, but it is also possible to provide a conventional mold half without a molded shell for the upper part of the tool.

Weiterhin wurde erkannt, wie die benötigte Formschale auf einfache Weise hergestellt werden kann. Hierzu ist es nämlich lediglich erforderlich, im Tiefziehwerkzeug unter Einsatz der Trägerformhälfte ohne eingesetzte Formschale sowie mit der entsprechenden Gegen-Formhälfte, d. h. der Oberform oder der Patrize eine Lage von zwei Blechen tiefzuziehen, von denen dann eines die Formschale 3 und das andere das im Tiefziehwerkzeug herzustellende Blechteil 5 ergibt. Es werden somit zwei Blechteile übereinanderliegend im Tiefziehwerkzeug ohne Formschale 3 tiefgezogen. Soll im übrigen auch die Gegenformhälfte eine Formschale besitzen, so können in einem einzigen Tiefzieh-Vorgang auch drei Bleche übereinanderliegend geformt werden, wobei das untere Blechteil die Formschale der unteren Formhälfte, das obere Blechteil die Formschale der oberen Formhälfte und das mittlere Blech das eigentlich tiefzuziehende Blechteil 5 ergibt.It was also recognized how the required molded shell can be manufactured in a simple manner. For this purpose, it is only necessary to use the carrier mold half without an inserted mold shell and with the corresponding counter-mold half, i. H. to deep-draw a layer of two sheets of the upper mold or patrix, one of which then gives the molded shell 3 and the other the sheet-metal part 5 to be produced in the deep-drawing tool. Two sheet metal parts are thus deep-drawn one above the other in the deep-drawing tool without a molded shell 3. In addition, if the counter-mold half should also have a molded shell, three sheets can be formed one above the other in a single deep-drawing process, the lower sheet metal part being the molded shell of the lower mold half, the upper sheet metal part being the molded shell of the upper mold half, and the middle sheet being actually deep-drawn Sheet metal part 5 results.

Jedoch kann dies sowie weitere Details durchaus abweichend vom gezeigten Ausführungsbeispiel gestaltet sein, ohne den Inhalt der Patentansprüche zu verlassen. Stets erhält man ein Tiefziehwerkzeug mit einer austauschbaren Formschale, das sich durch eine Reihe von Vorteilen auszeichnet. So kann wegen der Formschale 3 bei geeigneter Auswahl derselben beispielsweise auch der Schmiermittelverbrauch drastisch reduziert werden.However, this and other details can be designed quite differently from the exemplary embodiment shown, without leaving the content of the claims. You always get a deep-drawing tool with an interchangeable one Shaped shell, which is characterized by a number of advantages. For example, the lubricant consumption can be drastically reduced because of the molded shell 3 if the latter is selected appropriately.
