Das erfindungsgemäße Halbzeug aus Metall zeichnet sich dadurch aus, dass es einstückig ausgebildet ist und daß es vorbestimmte Abschnitte strukturiert und vorbestimmte Abschnitte nichtstrukturiert sind, wobei mindestens ein nicht-strukturierter Abschnitt ausgebildet ist als Verbindungsbereich zur stoff-, form- oder kraftschlüssigen Verbindung.

The metal semifinished product according to the invention is characterized in that it is designed in one piece and that it structures predetermined sections and unstructured predetermined sections, wherein at least one non-structured section is formed as a connection region to the material, positive or non-positive connection.

Stand der Technik State of the art
Flächige Halbzeuge aus Metall werden in verschiedenen technischen Bereichen eingesetzt. Solche Blechteile finden z.B. als wärme- oder schalldämmende Verkleidungen im Motorraum oder Unterbodenbereich von Kraftzeugen Anwendung. Aber auch als Schutzschilde gegen äußere Verschmutzungen oder Beschädigungen werden entsprechende Halbzeuge oder Formteile eingesetzt. Diese Halbzeuge oder Formteile werden üblicherweise aus Metallen, wie Stahl oder Edelstahl, aber auch aus Aluminium gefertigt. Dabei werden in einem ersten Schritt die Bleche verformt und geprägt. Mit Hilfe der Prägung erfolgt dabei eine Verfestigung der Bleche. Gleichzeitig wird durch Vergrößerung der Fläche ein verbesserter und dadurch optimierter Wärmefluss erzielt.

Wenn erforderlich, werden entsprechende Aussparungen aus dem Blech gestanzt oder geschnitten, um eine Verbindung dieser Bleche mit anderen Bauteilen zu erreichen. Häufig wird auch ein Verschweißen der Blechbauteile mit anderen Bauteilen verlangt. Diese Bleche finden, wie ausgeführt, Anwendung in der Automobilindustrie, insbesondere als schallabsorbierende Isolationspakete oder Hitzeschilde für Fahrzeuge. Üblicherweise werden zur Herstellung solcher Bleche Flach- oder Blattmaterialien durch ein Prägewalzenpaar geführt, um die gewünschte Struktur des Bleches zu erreichen. Solche Strukturierungen/ Prägungen können noppen-, wellen- oder rautenförmig sein. Bei dem Einsatz als schallabsorbierende Isolationspakete oder Hitzeschilde, wie z.B. im Fahrzeug- oder Automobilbau, werden diese Bleche als Stapel oder als Komposite in Verbindung mit anderen Isolationsmaterialien, wie mineralischen Isolier- oder Dämmmaterialien oder solchen auf Stahlfaserbasis, verwendet. Diese Komposite erlauben eine gute Wärmeabführung bei gleichzeitig erfolgender Schallabsorbierung. CONFIRMATION COPY wise embossed semi-finished products produced as a board or roll goods are then processed in a further processing step, eg in a cutting process. If necessary, corresponding recesses are punched or cut out of the sheet metal in order to connect these sheets to other components. Frequently, a welding of the sheet metal components with other components is required. As stated, these sheets are used in the automotive industry, in particular as sound-absorbing insulation packages or heat shields for vehicles.

Allerdings zeigen die bisher bekannten Verfahren und die dadurch hergestellten Metallbleche Nachteile auf. So sind diese strukturierten Bleche bei der weiteren Bearbeitung nachteilig, da bei der Nachbearbeitung, wie z.B. bei Schneidprozessen, keine plane Fläche erhalten wird, die ein Verbinden, z.B. ein Verschweißen, erleichtert. Weiterhin können keine exakten Schnittlinien bei Schneidprozessen erhalten werden, um z.B. exakte Bördelkanten zu erhalten. Auch die Bereiche mit Aussparungen zur stoff-, form- oder kraftschlüssigen Verbindung mit einem weiteren Bauteil, z.B. durch Schrauben etc., sind durch die Strukturierung nicht optimal ausgebildet, da aufgrund der Strukturierung die Kanten der Aussparungen nicht plan sind und somit eine entsprechende stoff- oder kraftschlüssige Verbindung erschwert wird. Um dieses zu erreichen, sind umfangreiche Nacharbeiten notwendig, wie ein erneutes Plätten der bereits strukturierten Flächen. Alternativ wurden Bauteile aus Einzelelementen aufbauend entwickelt, die insbesondere auch verschiedene Materialien aufweisen, wie Kunststoffe und Metalle. Diese Einzelelemente für die verschiedenen Bereiche des Halbzeug bzw. des Bauteils werden dann in weiteren Arbeitsschritten miteinander verbunden, z.B. durch Verkleben oder mit entsprechend geeigneten Mitteln. Dadurch müssen aber weitere arbeitsintensive Schritte bei der Herstellung durchgeführt werden. However, the previously known methods and the metal sheets produced thereby show disadvantages. Thus, these structured sheets are disadvantageous in the further processing, since in the post-processing, such as in cutting processes, no flat surface is obtained, which facilitates a connection, for example a welding. Furthermore, no exact cutting lines can be obtained in cutting processes, for example, to obtain exact flanging edges. The areas with recesses for material, positive or non-positive connection with another component, for example by screws, etc., are not optimally formed by the structuring, since due to the structuring of the edges of the recesses are not plan and thus a corresponding material or non-positive connection is difficult. In order to achieve this, extensive reworking is necessary, such as re-flattening the already structured surfaces. Alternatively, components have been developed from individual elements, which in particular also comprise different materials, such as plastics and metals. These individual elements for the different areas of the semifinished product or of the component are then connected to one another in further work steps, for example by gluing or with correspondingly suitable means. As a result, however, further labor-intensive steps in the production must be carried out.
Es besteht daher ein Bedarf nach Halbzeugen oder Bauteilen aus Metall, die insbesondere im Fahrzeugbereich eingesezt werden können, die die oben genannten Nachteile überwinden und die mit einem einfachen Verfahren erhältlich sind. There is therefore a need for semi-finished products or components made of metal, which can be used in particular in the vehicle sector, which overcome the above-mentioned disadvantages and which are obtainable with a simple method.

Diese Aufgabe wird durch die in den Patentansprüchen 1 , 8 und 10 angegebene Erfindung gelöst. Die Unteransprüche enthalten vorteilhafte Weiterbildungen der Erfindung.  The object of the invention is the provision of such components made of metals, in particular suitable as mudguards, thermal insulation and / or insulating in the vehicle area, with these components an improved connection with other components is possible and these components can be provided by a simpler process.

Die Halbzeuge sind dabei bevorzugt aus einem einzelnen Metall hergestellt. Diese Halbzeuge finden insbesondere Verwendung als Schutzbleche, Wärmedämm— oder Isolierbleche für den Fahrzeugbereich. Des Weiteren richtet sich die vorliegende Erfindung auf ein Verfahren zur Herstellung von erfindungsgemäßen flächigen Halbzeugen aus Metall umfassend den Schritt des einstufigen Pressens oder Prägens von Metallblechen mit geeigneten Werkzeugen, wobei diese Werkzeuge derart ausgebildet sind, dass sie vorbestimmte strukturierte und nichtstrukturierte Abschnitte aufweisen und so in einem Schritt gleichzeitig struktierte und nicht-struktierte Abschnitte im Metallblech ausbilden können, zur Herstellung eines flächigen Halbzeugs, das insbesondere ein einstückiges Halbzeug ist. In a first aspect, the present invention relates to sheet metal semi-finished products, wherein this semifinished product has at least one structured and at least one non-structured section, wherein this semi-finished product has non-structured edge sections and this semifinished product has a high elasticity due to the structuring. characterized in that the semi-finished product has at least one predetermined structured portion and at least one predetermined non-structured portion and the structured portions are optionally differently embossed portions, wherein at least one non-structured portion is formed as a connecting region to the fabric, molded or non-positive connection. The semi-finished products are preferably made of a single metal. These semi-finished products are used in particular as mudguards, thermal insulation or insulating panels for the vehicle sector. Furthermore, the present invention is directed to a method for the production of sheet metal semi-finished products according to the invention comprising the step of single-stage pressing or embossing metal sheets with suitable tools, wherein these tools are designed such that they have predetermined structured and non-structured sections and thus in a step simultaneously structured and non-structured sections can form in the metal sheet, for the production of a flat semi-finished product, which is in particular a one-piece semi-finished product.
Aufgrund der nicht-strukturierten Abschnitte im Randbereich und im Bereich, ausgebildet als Verbindungsbereich zur stoff-, form- oder kraftschlüssigen Verbindung mit einem weiteren Bauteil, sind aufwendige Nacharbeiten an dem Halbzeug überflüssig. Die nichtstrukturierten Abschnitte sind dabei so vorbestimmt, dass diese mit den Randbereichen des Halbzeugs und den Verbindungsbereichen des Halbzeugs mit anderen Bauteilen oder mit einem weiteren oder dem gleichen nicht-strukturierten Bereich des Bauteils selbst übereinstimmen. Strukturierte Abschnitte finden sich bevorzugt in den Abschnitten des Halbzeugs, die zum Wärmefluss oder zur Isolierung oder Dämmung vorgesehen sind. Die Halbzeuge zeichnen sich dadurch aus, dass sie exakte Schnittlinien aufweisen und in den Bereichen der Aussparungen plane, d.h. nicht-strukturierte Flächen aufzeigen und bevorzugt einstückig ausgebildet ist. Strukturierte Flächen sind insbesondere da ausgebildet, wo eine Verstärkung bzw. eine Wärmeflussoptimierung erforderlich sind. Due to the non-structured sections in the edge region and in the region, designed as a connection region for material, positive or non-positive connection with another component, expensive reworking of the semifinished product is superfluous. The non-structured sections are predetermined so that they coincide with the edge regions of the semifinished product and the connecting regions of the semifinished product with other components or with a further or the same non-structured region of the component itself. Structured sections are preferably found in the sections of the semifinished product intended for heat flow or for insulation or insulation. The semi-finished products are characterized in that they have exact cutting lines and plane in the areas of the recesses, ie show non-structured surfaces and is preferably integrally formed. Structured surfaces are in particular formed where reinforcement or heat flow optimization is required.
Durch die gezielten nicht-strukturierten Bereiche, d.h. die vorbestimmten nicht-strukturierten Abschnitte in den flächigen Halbzeug, ist es möglich mit anderen Bauteilen oder nicht-strukturierten Bereichen desselben Bauteils, z.B. mittels Verschweißen, Verschrauben, Vernieten, Toxen oder andere Arten mechanischer Verbindungen passgenau mit anliegenden Flächen eine Verbindung auszubilden, d.h. diese Bereiche sind besonders geeignet zur stoff-, form- oder kraftschlüssigen Verbindung von Bauteilen. Due to the targeted non-structured areas, i. the predetermined non-structured portions in the sheet semifinished product, it is possible with other components or non-structured portions of the same component, e.g. by means of welding, bolting, riveting, toxing or other types of mechanical connections, to make a fitting fit with adjacent surfaces, i. These areas are particularly suitable for the material, positive or non-positive connection of components.
Die strukturierten und nicht-strukturierten Abschnitte werden des weiteren so vorbestimmt angeordnet, dass angrenzende Bauteile entsprechend eng angeordnet werden können, ohne auf umliegende Strukturprägungen verzichten zu müssen bzw. ohne diese Bereiche bei vorstrukturierten Flächen mit einem weiteren Verarbeitungsschritt erneut zu glätten. Die erneute Glättung und damit eine weitere Strapazierung des Materials wird vermieden und damit einer Rissbildung vorgebeugt. Dieses führt speziell z.B. im Verschrau- bungsbereich zu verbesserter dauerhafter Stabilität. The structured and non-structured sections are furthermore arranged in a predetermined manner so that adjoining components can be correspondingly tightly arranged without having to forego surrounding structural embossing or without again smoothing out these areas in the case of pre-structured surfaces with a further processing step. The re-smoothing and thus a further strain on the material is avoided and thus prevents cracking. This leads specifically e.g. in the screwing area for improved lasting stability.
Die vorbestimmten nicht-strukturierten Abschnitte können des weiteren den Schnittbereichen entsprechen, insbesondere bei Coil- und Platinenmaterial, um die fertigen Bauteile entsprechend aus der Rollenware bzw. den tafelförmigen Halbzeugen auszuschneiden. The predetermined non-structured portions may further correspond to the intersection areas, particularly in coil and board material, to cut out the finished components from the roll stock or tabular stock.
Die erfindungsgemäßen flächigen Halbzeuge aus Metall können da- bei tafelförmig vorliegen oder als Rollenware konfektioniert sein. Insbesondere sind diese flächigen Halbzeuge einstückige Halbzeuge und nicht aus Einzelelementen z.B. durch Verkleben von Einzelelementen aus verschiedenen Materialien, ausgebildet. The flat metal semi-finished products according to the invention can be tabular or preformed as a roll. In particular, these flat semi-finished products are integral semi-finished products and not of individual elements, for example by gluing individual elements made of different materials.
Die Halbzeuge aus Metall sind dabei bevorzugt solche, die aus Zink, Messing, Kupfer, Aluminium, Stahl und Edelstahl alleine oder Kombinationen dieser bestehen. The metal semi-finished products are preferably those made of zinc, brass, copper, aluminum, steel and stainless steel alone or combinations thereof.
Die strukturierten Abschnitte sind insbesondere solche, die Sicken-, Kalotten- und/oder eine Grobkornprägung aufweisen. Die Prägung kann noppen-, wellen- oder rautenförmig vorliegen. Die Prägungen können dabei unterschiedliche Richtungen aufzeigen, d.h. in vertikaler und horizontaler Ausprägungsrichtung. Die Strukturen können dabei gleich hoch oder verschieden hoch sein. Des Weiteren können die Strukturen nur auf einer Seite des Halbzeugs ausgebildet sein. Das heißt, die strukturierten Abschnitte können unterschiedliche Strukturen aufzeigen, je nach Anforderungen an diese Abschnitte, z.B. zur Optimierung des Wärmeflusses oder zur Verfestigung dieser Bereiche. The structured sections are in particular those which have bead, dome and / or coarse grain embossing. The embossing may be nubbed, wavy or diamond-shaped. The embossments can show different directions, i. in vertical and horizontal direction of expression. The structures can be the same height or different heights. Furthermore, the structures may be formed only on one side of the semifinished product. That is, the structured sections may exhibit different structures, depending on the requirements of these sections, e.g. to optimize the heat flow or to solidify these areas.
Bevorzugt weist mindestens ein nicht-strukturierter Bereich mindestens eine Aussparung auf, um ein form- oder kraftschlüssiges Verbinden zu erlauben. In einer weiteren bevorzugten Ausführungsform sind alle Randabschnitte nicht strukturiert. Preferably, at least one non-structured region has at least one recess in order to allow a positive or non-positive connection. In a further preferred embodiment, all edge sections are not structured.
Das erfindungsgemäße Verfahren zur Herstellung des flächigen Halbzeugs aus Metall gemäß der vorliegenden Erfindung umfasst den Schritt des Pressens oder Prägens des bevorzugt einstückigen Metallblechs mit entsprechenden Werkzeugen, wobei diese Werkzeuge derart ausgebildet sind, dass in vorbestimmten Abschnitten strukturierte und nicht-strukturierte Abschnitte ausgebildet werden, um das Herstellen des erfindungsgemäßen flächigen Halbzeugs zu erlauben. In einem Umformschritt können somit gleichzeitig struk- tierte und nicht-struktierte Abschnitte im Metallblech ausgebildet werden. The method according to the invention for producing the sheet metal semifinished product according to the present invention comprises the step of pressing or embossing the preferably one-piece metal sheet with corresponding tools, wherein these tools are designed such that structured and non-structured portions are formed in predetermined portions, to allow the production of the flat semifinished product according to the invention. In a forming step, structured and non-structured sections can thus be formed in the metal sheet at the same time.
Das erfindungsgemäße Verfahren kann dabei mittels Druckwerkzeugen, bestehend aus einem Ober- oder Unterwerkzeug, durchgeführt werden. Alternativ kann es sich um ein Rotationsprägen zwischen gegenläufigen Walzen, die jeweils die Struktur der zu prägenden Matrixgeometrie beinhalten, durchgeführt werden. Eine weitere Alternative stellt ein rotationsprägendes Verfahren dar, wobei nur zwischen gegenläufigen Walzen, bei denen nur eine die Struktur der zu prägenden Matrixgeometrie darstellt und die andere eine Oberfläche aus einem Überzug enthält, der die Struktur aufnimmt, z.B. Gummi. The method according to the invention can be carried out by means of printing tools consisting of a top or bottom tool. Alternatively, it may be a rotary embossing between opposing rollers, each of which includes the structure of the matrix geometry to be embossed. A further alternative is a rotationally embossing process wherein only between opposing rolls, wherein only one represents the structure of the matrix geometry to be embossed and the other contains a surface of a coating which accommodates the structure, e.g. Rubber.
Das erfindungsgemäße Verfahren kann in einer weiteren alternativen Ausführungsform eines sein, bei dem durch Rotationsprägung das erfindungsgemäße Halbzeug hergestellt wird. Dabei wird nur eine Walze über eine Platine oder Coilphase hin bzw. auch hin und her gefahren. In a further alternative embodiment, the method according to the invention can be one in which the semifinished product according to the invention is produced by rotary embossing. Only one roller is moved over a board or coil phase or back and forth.
Das Rotationsverfahren ist z.B. eines mit Walzen mit variabler Körnerintensität und variabler Körnerzahl. Dabei können z.B. mittels eines konischen Dorns bzw. pneumatischen Backen diese Körner herausdrückbar ausgebildet sein, um die Körner in der Höhe bzw. auch über die Fläche der Walze mit unterschiedlicher Anzahl auszubilden. Dadurch können verschiedene Strukturen in einem Umformschritt mit einem Werkzeug ausgebildet werden. The rotation method is e.g. one with variable grain intensity and variable grain number rolls. Thereby, e.g. be formed herausdrückbar by means of a conical mandrel or pneumatic jaws these grains to form the grains in height or over the surface of the roller with a different number. As a result, various structures can be formed in a forming step with a tool.
Die Erfindung richtet sich weiterhin auf mit den erfindungsgemäßen Verfahren herstellbare, bevorzugt einzelstückige Halbzeuge. Weiterhin richtet sich die vorliegende Erfindung auf bevorzugt einzelstückige Bauteile aus einem erfindungsgemäßen flächigen Halbzeug aus Metall. Diese Bauteile sind insbesondere derart ausgebildet, dass sie als Bauteile für Schutzbleche, Wärmedämm- oder Isolierbleche im Fahrzeugbereich geeignet sind. The invention is further directed to obtainable by the method according to the invention, preferably single-piece semifinished products. Furthermore, the present invention is directed to preferably single-piece components of a flat semi-finished product according to the invention made of metal. These components are in particular designed such that they are suitable as components for mudguards, heat insulation or insulating in the vehicle area.
Unter Bezugnahme auf die Abbildungen wird die Erfindung im Folgenden weiter erläutert. With reference to the figures, the invention will be further explained below.
Die Abbildung 1 zeigt einen Ausschnitt von formschlüssig verbundenen erfindungsgemäßen Halbzeugen aus Metall 1 , mit strukturierten Abschnitten 2 und nicht-strukturierten Randabschnitten 4. Die erfindungsgemäßen flächigen einstückigen Halbzeuge erlauben durch die im einstufigen Umform verfahren hergestellten nicht- strukurierten Bereiche der Randbereiche 4 ein formschlüssiges Verbinden dieser Halbzeuge. Die strukturierten Bereiche 2 erlauben optimierten Wärmefluss und Stabilität. Figure 1 shows a section of form-fitting connected semifinished products according to the invention of metal 1, with structured sections 2 and non-structured edge sections 4. The flat one-piece semifinished products according to the invention allow a form-locking connection of the non-structured regions of the edge regions 4 produced in the single-stage forming process semi-finished products. The structured areas 2 allow optimized heat flow and stability.
Die Abbildung 2 zeigt eine erfindungsgemäße Ausführungsform des flächigen Halbzeugs 1 mit unterschiedlichen strukturierten Abschnitten (2.1 , 2.2) und nicht-strukturierten Abschnitten 3 und 4. Der nicht-strukturierte Abschnitt 3 weist eine Aussparung 5 auf. Mit Hilfe dieser Aussparung 5 in dem nicht-strukturierten Abschnitt 3 ist z.B. ein kraftschlüssiges Verbinden des erfindungsgemäßen Halbzeugs mit einem anderen Bauteil möglich. Der strukturierte Abschnitt 2 ist in zwei unterschiedliche Abschnitte 2.1 und 2.2 eingeteilt. Dabei unterscheiden sich die vorliegenden strukturierten Abschnitte durch unterschiedliche Höhen der Ausprägungen. Der nicht-strukturierte Abschnitt 3 ist als Vertiefung ausgebildet, um eine Verbindung mit einem anderen Bauteil durch ein entsprechendes Verbindungsmittel, wie über Schraubverbindungen, die durch die Aussparung 5 geführt werden, zu ermöglichen. Der Randabschnitt 4 ist ebenfalls als nichtstrukturierter Bereich ausgebildet, um ein Verbindungen mit einem anderen Bauteil zu erlauben. Über die nicht-strukturierten Bereiche ist eine mechanische Verbindung durch z.B. Nieten, Toxen, Ver- schrauben möglich aber auch durch Schweißen oder Kleben. 2 shows an embodiment according to the invention of the flat semi-finished product 1 with different structured sections (2.1, 2.2) and non-structured sections 3 and 4. The non-structured section 3 has a recess 5. With the help of this recess 5 in the non-structured section 3, for example, a non-positive connection of the semifinished product according to the invention with another component is possible. The structured section 2 is divided into two different sections 2.1 and 2.2. In this case, the present structured sections differ by different heights of the characteristics. The non-structured portion 3 is formed as a recess to connect to another component by a corresponding connecting means, such as via screw, which led through the recess 5 to be possible. The edge portion 4 is also formed as a non-structured area to allow a connection with another component. A mechanical connection is possible over the non-structured areas, eg by riveting, tearing, screwing, but also by welding or gluing.
In der Abbildung 3 ist ein Ausschnitt eines erfindungsgemäßen flächigen Bauteils 1 gezeigt, wobei diese strukturierten Abschnitte 2.1 , 2.2 und 2.3 mit unterschiedlichen Höhen und unterschiedlichen Richtungen aufzeigt. Das heißt, die Abschnitte zeigen zum einen Ausprägungen unterschiedlicher Höhe, Abschnitte 2.1 , 2.2 und 2.3. Des Weiteren unterscheiden sich die Ausprägungen des Abschnitts 2.1 von denen der Abschnitte 2.2 und 2.3 darin, dass die Mittelachse der Ausprägungen im Abschnitt 2.1 geneigt sind während die Mittelachse in den Abschnitten 2.2 und 2.3 lotrecht steht. Durch die Ausgestaltung der verschiedenen strukturierten Abschnitte ist ein optimierter Wärmefluss möglich. Die verschiedenen Strukturen erlauben des Weiteren die Ausbildung unterschiedlicher Stabilitäten. Mit Hilfe des erfindungsgemäßen Verfahrens lassen sich die erfindungsgemäßen flächigen Halbzeuge in einem Umformschritt herstellen. Dadurch werden weitere Bearbeitungsschritte vermieden, insbesondere solche Schritte bei denen die strukturierten Abschnitte erneut geglättet werden müssen und damit einer weiteren Strapazierung des Materials erfolgt. Dadurch wird in den Verbindungs- und Befestigungsbereichen eine dauerhafte Verbesserung der Materialeigenschaften erzielt. Bezugszeichen: FIG. 3 shows a section of a planar component 1 according to the invention, wherein these structured sections 2.1, 2.2 and 2.3 have different heights and different directions. That is, the sections show on the one hand characteristics of different heights, sections 2.1, 2.2 and 2.3. Furthermore, the characteristics of section 2.1 differ from those of sections 2.2 and 2.3 in that the central axis of the characteristics in section 2.1 are inclined while the central axis in sections 2.2 and 2.3 is perpendicular. Due to the design of the various structured sections, an optimized heat flow is possible. The various structures also allow the formation of different stabilities. With the aid of the method according to the invention, the sheet-like semi-finished products according to the invention can be produced in a forming step. As a result, further processing steps are avoided, in particular those steps in which the structured sections must be smoothed again and thus further stressing of the material takes place. As a result, a lasting improvement in the material properties is achieved in the connection and fastening areas. REFERENCE NUMBERS
