Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Formteils gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for producing a molded part according to the preamble of claim 1.
Ein gattungsgemäßes Verfahren ist bekannt geworden aus der DE-41 04 256-A1 (B23K 26/08). Dort wird insbesondere am Beispiel von Karosserieteilen für Personen- und Last kraftwagen erläutert, wie hoch belastete lokale Bereiche (Scharnieraufnahmen, Schloßver stärkungen, Ansatzbereiche für Holme oder sonstige tragende Elemente) wirkungsvoll ver stärkt werden können. Im Ergebnis werden bei dem gattungsgemäßen Verfahren Formteile erstellt, die auch als so genannte tailored blanks bekannt geworden sind (siehe hierzu VDI- Berichte Nr. 1002, 1993, Seite 45 bis 51). In der letztgenannten Schrift wird insbesondere am Beispiel eines Türinnenbleches gezeigt, wie durch größere Blech dicken im Bereich der Scharnier- und Schloßbefestigung eine ausreichende Steifigkeit erzeugt wird. Die Ge wichtsersparnis erbringt da bei ein zwischen dickeren Blechen eingebrachtes Dünnblech. Nachteilig an diesen Blechen ist die Tatsache, daß sie im Grunde genommen nur für Formteile verwendet werden können, die am fertigen Produkt nicht sichtbar sind. Beide vor genannten Schriften stellen explizit auf Formkörper ab, die entweder selbst Innenteil eines Teileverbundes sind oder durch gesonderte Formteile auf einer inneren Teilfläche mit Störung der äußeren Oberfläche verstärkt sind.A generic method has become known from DE-41 04 256-A1 (B23K 26/08). There is particularly the example of body parts for people and loads motor vehicles explains how heavily used local areas (hinge mounts, lock ver reinforcements, attachment areas for spars or other load-bearing elements) can be strengthened. As a result, molded parts are used in the generic method created, which have also become known as tailored blanks (see VDI- Reports No. 1002, 1993, pages 45 to 51). In the latter document, in particular using the example of a door inner panel, as shown by thicker panels in the area of Hinge and lock fastening sufficient rigidity is generated. The Ge This saves weight when a thin sheet is inserted between thicker sheets. A disadvantage of these sheets is the fact that they are basically only for Molded parts can be used that are not visible on the finished product. Both before the above-mentioned writings explicitly focus on moldings that are either the inner part of a Composite parts or with separate molded parts on an inner part surface Disturbance of the outer surface are aggravated.
Die EP-0 486 093-B1 beschreibt ein Verfahren, bei dem die Verstärkung von Teilbereichen eines Formteils mittels eines verstärkenden Strukturgliedes erfolgt, das von dem zu be deckenden Plattenkörper getrennt verformt wird und erst anschließend mit dem ebenfalls fertiggeformten Plattenkörper verbunden wird. Damit ist der Formgebungsprozeß kompli zierter und aufwendiger als bei den oben beschriebenen tailored blanks.EP-0 486 093-B1 describes a method in which the reinforcement of partial areas of a molded part by means of a reinforcing structural member, which is to be covering plate body is deformed separately and only then with the likewise finished molded plate body is connected. This complicates the molding process more elegant and complex than the tailored blanks described above.
Der Erfindung liegt die Aufgabe zugrunde, für Formteile mit unterschiedlichen Material stärken ein Verfahren bereitzustellen, durch das die oben genannten Nachteile vermieden werden können. The invention is based, for molded parts with different material the task strengthen a process by which the disadvantages mentioned above are avoided can be.
Diese Aufgabe wird gelöst mit einem Verfahren gemäß dem Patentanspruch 1. Die Unter ansprüche betreffen besonders vorteilhafte Ausgestaltungen dieses Verfahrens sowie ver fahrensgemäß erzeugte Formteile.This object is achieved with a method according to claim 1. The sub claims relate to particularly advantageous embodiments of this method and ver molded parts produced according to driving style.
Erfindungsgemäß wird also auf einem lokal zu verstärkenden Bereich einer Basisplatine wenigstens ein plattenförmiges Verstärkungselement befestigt, und zwar vorzugsweise mit einer bewährten Fügetechnik wie Kleben, Löten, Schweißen, Clinchen oder Kombinationen dieser Fügeverfahren. Der auf diese Weise hergestellte und ggf. auch mehrlagig (beispiels weise nach Art eines Sandwich) ausgebildete Schichtkörper wird anschließend einem Formgebungsprozeß unterzogen, beispielsweise in einer Tiefziehpresse, Abkantbank oder in einer Falzvorrichtung. Sämtliche der oben genannten Fügetechniken können so ausge führt werden, daß die Anbringung von Verstärkungselementen auf der gegenüberliegenden Seite der Basisplatine nicht sichtbar ist. Damit können besonders vorteilhaft auch Außen bleche für Türen, Motorhauben, Kofferraumdeckel und Heckklappen mit dem erfindungs gemäßen Verfahren hergestellt werden. Das bei der Herstellung von tailored blanks er worbene Know-how bezüglich der Formgebung von Platinen mit unterschiedlichen Material stärken kann in vorteilhafter Weise für das erfindungsgemäße Verfahren in weiten Teilen genutzt werden.According to the invention, this is based on a region of a base board that is to be locally reinforced attached at least one plate-shaped reinforcing element, preferably with a proven joining technology such as gluing, soldering, welding, clinching or combinations this joining process. The manufactured in this way and possibly also in multiple layers (for example layered body formed in the manner of a sandwich) is then one Shaped molding process, for example in a deep-drawing press, press brake or in a folder. All of the above joining techniques can be so leads to the attachment of reinforcing elements on the opposite Side of the base board is not visible. This can also be particularly advantageous outside Sheets for doors, bonnets, trunk lids and tailgates with the invention be produced according to the method. He does that in the production of tailored blanks know-how regarding the shaping of boards with different materials Strengthening can be advantageous for the method according to the invention in large parts be used.
Besondere Vorteile des erfindungsgemäßen Verfahrens sind darin zu sehen, daß die raumliche Ausdehnung der Verstärkungselemente auf ein Minimum begrenzt werden kann. Das gesamte Formteil ist damit nur genau dort verstärkt, wo dies auch unbedingt notwendig ist. Darüberhinaus bietet das erfindungsgemäße Verfahren ausgezeichnete Möglichkeiten für eine Massenfertigung, weil die plattenartig ausgeführten und damit weitgehend ebenen Verstärkungselemente auf eine ebenfalls weitgehend ebene Basisplatine mit einfachen Klemm- oder Spannelementen festgelegt werden können. So kann beispielsweise direkt nach der Ablängung von einem Blechcoil eine Heft- und/oder Fügestation vorgesehen werden, um so ein aus Basisplatine und Verstärkungselementen gebildetes Verbundteil für den Formgebungsprozeß konfektionieren zu können.Particular advantages of the method according to the invention are that the spatial expansion of the reinforcing elements can be limited to a minimum. The entire molded part is only reinforced where it is absolutely necessary is. In addition, the method according to the invention offers excellent possibilities for mass production, because the plate-like and therefore largely flat Reinforcing elements on a likewise largely flat base board with simple ones Clamping or tensioning elements can be set. For example, directly after cutting to length from a sheet coil, a stitching and / or joining station is provided are so as to form a composite part made of base plate and reinforcing elements for to be able to assemble the shaping process.
Das erfindungsgemäße Verfahren ist grundsätzlich auf Stahl- und Leichtmetallwerkstoffe anwendbar. Hervorzuheben ist aber auch, daß unterschiedliche Werkstoffe oder unter schiedliche Werkstoffqualitäten miteinander kombiniert werden können, um so im Hinblick auf Festigkeit, Optik und Kosten jeweils zu einem optimalen Ergebnis gelangen zu können.The method according to the invention is basically based on steel and light metal materials applicable. It should also be emphasized that different materials or under different material qualities can be combined with each other, so with regard to to achieve optimal results in terms of strength, appearance and costs.
Gemäß einer besonders vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens werden die Verstärkungselemente aus Schnittabfällen erzeugt, und zwar vorzugsweise aus solchen, die beim Ausstanzen von Ausnehmungen des herzustellenden Formteils oder anderer Formteile entstehen.According to a particularly advantageous development of the method according to the invention the reinforcing elements are produced from cut waste, preferably from those that when punching recesses of the molded part or other molded parts arise.

Fig. 2 bis 6 den Zustand des Formteils gemäß Fig. 1 in einzelnen Verfahrensstufen. Fig. 2 to 6 the state of the molded part according to Fig. 1 in the individual process steps.
Man erkennt in Fig. 1 am Beispiel eines Türinnenbleches die Anwendung des erfindungs gemäßen Verfahrens. Auf eine gestrichelt angedeutete Platine 1, die im Ausgangszustand (siehe Fig. 2) weitgehend eben ist, werden zunächst Scharnierverstärkungselemente 2 und 3 sowie ein Schloßverstärkungselement 4 aufgebracht (siehe Fig. 3). Im vorliegenden Falle erfolgt die Befestigung der Verstärkungselemente 2 bis 4 über diese zumindest teil weise umrandende Kehlschweißnähte. Als bevorzugtes Fügeverfahren zur Befestigung der Verstärkungselemente 2 bis 4 wird das Schweißen mit einem hochenergetischen Strahl, also beispielsweise Laserschweißen oder Elektronenstrahlschweißen, eingesetzt. Diese Schweißverfahren eignen sich besonders zur Festlegung von Freiformkonturen. Auch die Verschweißung unterschiedlicher Werkstoffarten kann mit diesen Verfahren gut beherrscht werden. Die Breite und Tiefe der Schweißnaht kann dabei so eingestellt werden, daß auf der den Verstärkungselementen 2 bis 4 gegenüberliegenden Seite auch bei relativ dünnen Blechen (0,8 bis 1,5 mm) keine Beeinträchtigung der Oberfläche erfolgt. Insbesondere für Außenhautteile wird eine Verklebung, ggf. kombiniert mit Laserschweißung, verwendet.One can see in Fig. 1 using the example of a door inner panel, the application of the inventive method. Hinge reinforcing elements 2 and 3 and a lock reinforcing element 4 are first applied to a circuit board 1 indicated by dashed lines, which is largely flat in the initial state (see FIG. 2) (see FIG. 3). In the present case, the reinforcement elements 2 to 4 are attached via these fillet weld seams, which at least partially surround them. Welding with a high-energy beam, for example laser welding or electron beam welding, is used as the preferred joining method for fastening the reinforcing elements 2 to 4 . These welding processes are particularly suitable for determining free-form contours. The welding of different types of materials can also be mastered well with these processes. The width and depth of the weld seam can be adjusted so that on the side opposite the reinforcing elements 2 to 4 there is no impairment of the surface even with relatively thin sheets (0.8 to 1.5 mm). Bonding, possibly combined with laser welding, is used in particular for outer skin parts.
Nach der Befestigung der ggf. auch mehrlagig aufgebauten Verstärkungselemente 2 bis 4 werden beispielsweise durch Ausstanzung eine Fensterausnehmung 5, eine einem Fen sterschacht gegenüberliegende Ausnehmung 6 und eine Lautsprecherausnehmung 7 hergestellt (siehe Fig. 5). Darüber hinaus kann an dieser Stelle auch ein erster Beschnitt oberhalb einer Türschrägen erfolgen. Die bei der Herstellung der Ausnehmungen 5 bis 7 erzeugten Abfallplatinen können in Stanz- oder thermischen Schneidanlagen für die Neuan fertigung von weiteren Verstärkungselementen 2 bis 4 genutzt werden. Damit ergibt sich bezogen auf den Ausgangszustand der Platine 1 eine große Materialausbeute. Das gemäß Fig. 5 hergerichtete Verbundteil wird anschließend einer Tiefziehpresse zugeführt und in dieser zu dem in Fig. 1 dargestellten Türinnenblech um geformt und ggf. auch noch weiter beschnitten. Es wird an dieser Stelle ausdrücklich darauf hingewiesen, daß das erfindungs gemäße Verfahren aber auch auf Türaußenbleche angewendet werden kann. Zur Einbrin gung lokaler Verstärkungen eröffnen sich damit dem Konstrukteur von Karosserieteilen größere Gestaltungsmöglichkeiten. Dies kann insbesondere auch dann wichtig werden, wenn beispielsweise für in Fahrzeugen verwendete Formteile Akustikprobleme zu beheben sind. Durch die gezielte Anbringung von Verstärkungselementen kann beispielsweise mit nur geringem Aufwand eine Entdröhnung vorgenommen werden. Verstärkungselemente können auch als Tragteile für dem jeweiligen Formteil zugeordnete Bedienelemente genutzt werden. Dabei können die jeweiligen Verstärkungselemente auch schon durch gezielte Lochungen oder Konturgestaltungen, die vor der Befestigung auf der Platine 1 vorgenom men worden sind, auf ihre Tragfunktion vorbereitet werden.After the reinforcement elements 2 to 4 , which may also have a multi-layer structure, are fastened, a window recess 5 , a recess 6 opposite a fen slot shaft and a loudspeaker recess 7 are produced, for example, by punching out (see FIG. 5). In addition, a first trimming can be carried out at this point above a door slope. The waste boards generated in the manufacture of the recesses 5 to 7 can be used in punching or thermal cutting systems for the new production of further reinforcing elements 2 to 4 . This results in a large material yield based on the initial state of the circuit board 1 . The composite part prepared in accordance with FIG. 5 is then fed to a deep-drawing press and formed therein into the door inner panel shown in FIG. 1 and possibly also trimmed further. At this point, it is expressly pointed out that the method according to the invention can also be applied to outer door panels. In order to introduce local reinforcements, the designer of body parts opens up greater design options. This can be particularly important when acoustic problems need to be remedied, for example, for molded parts used in vehicles. The targeted attachment of reinforcing elements can, for example, be carried out with little effort. Reinforcing elements can also be used as supporting parts for operating elements assigned to the respective molded part. The respective reinforcement elements can also be prepared for their supporting function by targeted perforations or contour designs that have been carried out prior to attachment to the circuit board 1 .
Aus Vorstehendem ergibt sich, daß die nach Art eines Patchwork-Musters mit den Verstär kungselementen 2 bis 4 vorbereitete Basisplatine 1 sehr kostengünstig leichtbauend ist und darüber hinaus auch hohen Anforderungen an Optik und Akustik gerecht wird. Hervorzu heben ist auch, daß mit den erfindungsgemäß hergestellten Formteilen Oberflächenbe schichtungsverfahren wie Lackieren und Verzinken in konventionellen Anlagen durchgeführt werden können. Damit ist das erfindungsgemäße Verfahren auch ohne großen Aufwand in bereits bestehende Produktionskonzepte einbindbar.From the above it follows that the in the manner of a patchwork pattern with the reinforcement elements 2 to 4 prepared base board 1 is very inexpensive lightweight and also meets high demands on optics and acoustics. It should also be emphasized that surface molding processes such as painting and galvanizing can be carried out in conventional systems using the moldings produced according to the invention. The method according to the invention can thus be integrated into existing production concepts with little effort.
