Derartige Dekorformbauteile sind als dünnwandige, räumlich gegebenenfalls mehrdimensional gekrümmte Schalenbauteile ausgeführt, deren Herstellung einen entsprechenden Formgebungsprozeß erforderlich macht.Especially In automotive increasingly decorative moldings are used, the a visually sophisticated cladding of functional components like handles, steering wheels, Brake lever or the like. Serve. Such decorative molded components are as thin-walled, spatial optionally executed multi-dimensionally curved shell components whose Making a corresponding molding process required power.
Zur Erzielung eines anspruchsvollen, hochwertigen optischen Erscheinungsbildes werden Dekormaterialien wie Edelholzfurniere, Kohlefasergewebe, Metallbleche oder dgl. eingesetzt, wobei in einem Umformprozeß aus dem beispielsweise ebenen Dekormaterial ein Dekorvorformling als räumliches Gebilde ausgeformt wird. Anschließend kann der Dekorvorformling mit einem Trägermaterial verbunden und mit einer Klarsichtbeschichtung versehen werden. Im Laufe des Prozesses der Weiterverarbeitung ist ein konturgenauer Beschnitt des Dekorvorformlinges erforderlich, der beispielsweise durch Befräsen als zusätzlichen Arbeitsschritt erfolgen kann. Der Umformprozeß und der Beschnitt sind entsprechend aufwendig.to Achieving a sophisticated, high-quality visual appearance decorative materials such as precious wood veneers, carbon fiber fabrics, Metal sheets or the like. Used, in a forming process from the For example, even decorative material a decorative preform as a spatial entity is formed. Subsequently the decorative preform can be connected to a carrier material and with be provided a transparent coating. In the course of the process Further processing is a contour-accurate trimming of the decorative preform required, for example, by milling as an additional step can. The forming process and the trimming are correspondingly expensive.
Der Erfindung liegt die Aufgabe zugrunde, die Herstellung eines Dekorvorformlinges aus einem Dekormaterial zu vereinfachen.Of the Invention is based on the object, the production of a decorative preform from a decor material to simplify.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie durch eine Formvorrichtung mit den Merkmalen des Anspruchs 5 gelöst.The The object is achieved by a method having the features of the claim 1 and by a molding device with the features of claim 5 solved.
Es wird ein Verfahren sowie eine Formvorrichtung zur Herstellung eines Dekorvorformlings aus einem Dekormaterial vorgeschlagen, wobei die Formvorrichtung zwei in einer Schließrichtung aufeinander zu bewegbare Formhälften umfaßt. Eine der beiden Formhälften weist einen parallel zur Schließrichtung nachgiebig gelagerten und aus dieser Formhälfte hervorstehenden Niederhalter auf, wobei mindestens eine der beiden Formhälften mit einer Schneidkante versehen ist. Zur Herstellung des Dekorvorformlinges wird zunächst zwischen die beiden geöffneten Formhälften das Dekormaterial eingelegt. Anschließend werden die beiden Formhälften in der Schließrichtung aufeinander zu bewegt, wobei der nachgiebig gelagerte und hervorstehende Niederhalter zur Anlage an das Dekormaterial kommt. Im Laufe des Schließvorganges drückt der Niederhalter zunächst das Dekormaterial gegen die andere Formhälfte. Beim weiteren Schließvorgang erfolgt die Umformung des Dekormaterials zum Dekorvorformling, wobei gleichzeitig ein Beschnitt des Dekormaterials mittels der genannten Schneidkante erfolgt. Während des Schließvorganges der beiden Formhälften wird das Dekormaterial zuverlässig zwischen dem Niederhalter und der gegen-überliegenden Formhälfte gehalten. Während des weiteren Umformvorganges und des damit verbundenen Beschnitts ist das Dekormaterial zuverlässig fixiert. Ein Verrutschen oder ein Auswölben innerhalb der noch nicht vollständig geschlossenen Formhälften ist vermieden. Es ergibt sich eine exakte Formgebung mit einem präzise definierten Schnittverlauf.It is a method and a molding apparatus for producing a Decor preform proposed from a decorative material, wherein the molding device two in a closing direction mutually movable mold halves includes. One of the two mold halves has one parallel to the closing direction Completely stored and protruding from this mold half down on, wherein at least one of the two mold halves with a cutting edge is provided. For the preparation of the decorative preform is first between the two opened mold halves the decorative material inserted. Subsequently, the two mold halves in the closing direction moved towards each other, wherein the resiliently supported and protruding Downholder comes to rest on the decorative material. During the closing process presses the hold-down first the decorative material against the other mold half. During the further closing process the deformation of the decorative material takes place to the decorative preform, wherein at the same time a trimming of the decorative material by means of said Cutting edge takes place. While of the closing process the two mold halves is the decorative material reliable held between the hold-down and the opposing mold half. While the further forming process and the associated Beschnitts is the decorative material reliable fixed. A slipping or buckling within the not yet Completely closed mold halves is avoided. This results in an exact shaping with a precisely defined Callout.
Der Niederhalter kann hydraulisch, pneumatisch oder in anderer Weise nachgiebig gelagert sein und ist zweckmäßig gegen mindestens eine elastische Druckfeder abgestützt. Es ist ein einfacher und in der Wirkung zuverlässiger Aufbau gegeben. Insbesondere ist der Niederhalter in einem zumindest näherungsweise ebenen Formbereich angeordnet, in dem das Andrücken des Dekormaterials an die gegenüberliegende Formhälfte erfolgt. Dabei ist der Niederhalter zwar Teil der Form, ohne jedoch in seinem Wirkungsbereich eine nennenswerte eigenständige Formgebung zu bewirken. Der Fixierungsprozeß mittels des Niederhalters führt zu keiner eigenständigen Umformung, wodurch ein Verrutschen des Dekormaterials während des Andrückens vermieden ist.Of the Downholder can be hydraulic, pneumatic or otherwise be resilient and is useful against at least one elastic Supported compression spring. It is a simple and effective in the construction reliable given. Especially is the hold-down in an at least approximately flat shape area arranged in which the pressing of the decorative material to the opposite mold he follows. Although the hold-down is part of the form, but without in its sphere of action a significant independent shaping to effect. The fixation process by means of the hold-down leads to no independent Forming, whereby a slipping of the decorative material during the pressing of is avoided.
Der Beschnitt des Dekormaterials kann beispielsweise mit einer oder mehreren Schneidkanten an einer Formhälfte erfolgen, die während des Schließvorganges an einer entsprechend geformten Formfläche der anderen Formhälfte vorbeigeführt werden.Of the Trimming the decorative material can, for example, with a or several cutting edges on a mold half done during the closing process be passed past a correspondingly shaped mold surface of the other mold half.
Zweckmäßig sind jeder Formhälfte eine entsprechende Anzahl von Schneidkanten zugeordnet, die beim Beschnitt zusammenwirken. Die Schneidkanten der jeweils einen Formhälfte werden beim Schließvorgang an den zugeordneten Schneidkanten der anderen Formhälfte vorbeigeführt, wobei sich in ihrem Überschneidungsbereich eine präzise definierte Schnittlinie mit einem sauberen Schnittergebnis bildet.Are useful every mold half a corresponding number of cutting edges associated with the Trim together. The cutting edges of each one mold half during the closing process passed past the associated cutting edges of the other mold half, wherein in their overlapping area a precise one forms a defined cutting line with a clean cutting result.
In vorteilhafter Weiterbildung wird die Umformung des Dekormaterials unter Einwirkung von Wasserdampf durchgeführt. Dies ist insbesondere bei Dekormaterialien aus Holz oder aus holzähnlichen Werkstoffen zweckmäßig, wobei der Wasserdampf das Holzmaterial geschmeidig macht und hohe, gegebenenfalls auch räumlich mehrfach gekrümmte Umformungsgrade ermöglicht. Es ist dazu vorteilhaft mindestens eine Formhälfte mit mindestens einem Dampfkanal versehen, durch den Wasserdampf dem Dekormaterial zugeführt wird. Die Wasserdampfzufuhr kann bereits vor Beginn des Schließvorganges beider Formhälften beginnen und findet insbesondere während des Schließ-, Umformungs- und Beschnittvorganges statt.In an advantageous embodiment, the deformation of the decorative material is carried out under the action of water vapor. This is particularly useful in decorative materials made of wood or wood-like materials, the water vapor makes the wood material supple and high, possibly even spatially multiple curved Forming degrees possible. It is advantageous for at least one mold half provided with at least one steam channel through which water vapor is supplied to the decorative material. The steam supply can begin even before the beginning of the closing process of both mold halves and takes place in particular during the closing, forming and trimming process.
Der oder die Dampfkanäle sind zweckmäßig abseits vom Niederhalter und insbesondere in einem Formbereich von ausgeprägter Krümmung angeordnet. Der Wasserdampf kann präzise an die Orte geleitet werden, wo infolge des hohen Umformungsgrades ein entsprechender Bedarf an Wasserdampf vorliegt. Gleichzeitig ist der Einsatz von überflüssigen Dampfmengen vermieden. Das Holzmaterial erfährt eine nur geringe Anfeuchtung, die ohne übermäßige Trocknungszeiten eine Weiterverarbeitung ermöglicht.Of the or the steam channels are purposefully offside arranged by the hold-down and in particular in a molding area of pronounced curvature. The water vapor can be precise be directed to the places where due to the high degree of deformation there is a corresponding need for water vapor. simultaneously is the use of superfluous amounts of steam avoided. The wood material undergoes a only slight humidification, which without excessive drying times a Further processing possible.
