Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1 sowie ein Werkstück nach dem Oberbegriff des Patentanspruches 9.The invention relates to a method according to the preamble of Claim 1 and a workpiece according to the preamble of Claim 9.
In der Verarbeitungstechnik ist es ein wesentliches Ziel, das Gewicht von Werkstücken, z. B. Karosserieteile bei Kraftfahrzeu gen, Bau- und Konstruktionsteile, Verpackungswerkstoffe und dergl. zu verringern, ohne deren Festigkeit oder Steifigkeit zu beeinträchtigen. Beispiele hierfür bilden Plattenkonstruktio nen mit einem Steg, Wellpappe und Wellblech, Verbundtafeln und dergleichen mehr.In processing technology it is an essential goal that Weight of workpieces, e.g. B. body parts for motor vehicles gen, building and construction parts, packaging materials and to reduce the like, without increasing their strength or rigidity affect. Examples of this are plate construction with a web, corrugated cardboard and corrugated iron, composite panels and the like more.
Bekannt ist es auch, zwei Bleche durch z. B. Rollbonding an bestimmten Stellen so miteinander zu verbinden, daß die nicht behandelten Stellen einen oder mehr miteinander verbundene Kanäle bilden, die durch Einblasen von Druckluft aufgewölbt werden. Hierzu ist in der Regel die Schaffung eines Luftzugan ges am Werkstück und eine Gegenform erforderlich, was zu einem beträchtlichen Maschinenaufwand führt.It is also known to two sheets by z. B. Rollbonding to connect certain points so that they are not treated areas one or more interconnected Form channels that bulge out by blowing in compressed air become. This is usually done by creating an air inlet on the workpiece and a countermold required, resulting in a leads to considerable machine expenditure.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Werkstücken aus mehrlagig miteinander fest verbundenen dünnen, umformbaren Werkstücktafeln zu schaffen, das eine Gewichtseinsparung gegenüber gleichwertigen, aus homogenem Werkstoff gefertigten Werkstück bewirkt und billiger herstellbar ist, als das vorgenannte Aufpumpverfahren mit einer Einwirkung im Inneren des Verbundwerkstückes. Das erfindungsge mäße Verfahren soll weitestgehend ohne Verwendung von zusätzli chen Formwerkzeugen durchführbar sein und eine Massenfertigung gestatten.The invention has for its object a method for Production of workpieces from multi-layered solid to create connected thin, formable workpiece plates, that a weight saving compared to equivalent homogeneous material manufactured workpiece and cheaper is producible as the aforementioned inflation method with a Action inside the composite workpiece. The fiction Moderate procedure should largely without the use of additional Chen molds can be carried out and mass production allow.
Die Lösung der gestellten Aufgabe besteht erfindungsgemäß in den kennzeichnenden Merkmalen des Anspruches 1.According to the invention, the task is solved in the characterizing features of claim 1.
Durch die konvexe Aufwölbung mindestens einer Seite des Werkstückes wird die erforderliche Steifigkeit erreicht, die es gestattet, wesentlich dünnere Werkstofftafeln zu verwenden als bei der Herstellung des Werkstückes aus einer einlagigen Werkstofftafel.Due to the convex bulge of at least one side of the Workpiece the required rigidity is achieved allows to use much thinner sheets of material than in the manufacture of the workpiece from a single layer Material sheet.
Durch das erfindungsgemäße Verfahren erhält man ein Werkstück nach dem Oberbegriff des Anspruches 10 mit den kennzeichnenden Merkmalen dieses Anspruches.A workpiece is obtained by the method according to the invention according to the preamble of claim 10 with the characterizing Features of this claim.
Im Aussehen kann das Werkstück etwa demjenigen mit den aufgeblasenen Kanälen entsprechen. In vielen Fällen sind jedoch solche Kanalstrukturen nicht erwünscht, oder soll das Werkstück eine im wesentlichen gleichmäßig verteilte Struktur der Aufwölbungen aufweisen. In solchen Fällen ist das komplizierte re Aufblasverfahren auch nicht anwendbar.In terms of appearance, the workpiece can match the one with the inflated channels. In many cases, however such channel structures are not desired, or should be the workpiece an essentially evenly distributed structure of the Have bulges. In such cases it is complicated re inflation process also not applicable.
Zum Aufwölben der Werkstofftafeln von außen her eignen sich verschiedene Maßnahmen.Suitable for bulging the material sheets from the outside different measures.
Eine Behandlung mit einem mechanischen Strahlverfahren bewirkt durch eine Werkstoffverdrängung der behandelten Werkstofftafel einen einseitigen Verzug und damit eine Aufwölbung zwischen den Verbindungsstellen.Treatment with a mechanical blasting process causes by displacing the treated material sheet a one-sided delay and thus a bulge between the Joints.
In ähnlicher Weise kann sich auch eine Behandlung mit Wärmeeinwirkung und/oder Vakuum, ggf. mit Saugformen auswirken.Similarly, treatment can also be done with Effect of heat and / or vacuum, if necessary, use suction molds.
Dabei kommt es auch wesentlich auf die Anordnung und Ausführung der Verbindungsstellen an, die z. B. punkt- oder linienförmig sein können.It also depends on the arrangement and execution of the connection points that z. B. point or line could be.
Wenn eine Lage der Werkstofftafeln eine zur Tafel ebene senkrecht umgeformte Struktur hat und mit einer ebenen Tafel verbunden ist, ergibt sich ein entsprechend steifes Verbund werkstück. Bei vorgegebener Steifigkeit kann dabei bis etwa zur Hälfte des Werkstoffgewichtes gegenüber einem einlagigen Werkstück eingespart werden.If one layer of the material sheets is one level with the sheet vertically formed structure and with a flat board is connected, there is a correspondingly rigid bond workpiece. For a given stiffness can be up to Half of the material weight compared to a single layer Workpiece can be saved.
Das erfindungsgemäße Verfahren läßt es zu, daß das Werkstück nach der Verbindung der Werkstofftafeln und vor der Behandlung zur Erzeugung der Aufwölbungen in seine endgültige Gebrauchs form umgeformt, z. B. tiefgezogen wird. Dies gilt z. B. für Karosseriebleche.The method according to the invention allows the workpiece after joining the material sheets and before treatment to create the bulges in its final use shaped, z. B. is deep drawn. This applies e.g. B. for Body panels.
Dabei können die Seite mit den Aufwölbungen die nicht sichtbare Rückseite und die glatte Seite die Sichtseite des Werkstückes bilden.The side with the bulges can be the invisible one Back and the smooth side the visible side of the workpiece form.
Im Rahmen des erfindungsgemäßen Verfahrens ist es auch möglich, ein Werkstück aus Werkstofftafeln aus unterschiedlichen Werk stoffen zu bilden. Dabei kann es vorteilhaft sein, eine Werkstofftafel zu verwenden, deren Werkstoff bei einer thermi schen Einwirkung eine größere Volumenänderung erfährt als die andere Werkstofftafel. Dies kann für die Herstellung von Flüssigkeitsbehältern oder dergl. von Bedeutung sein oder von Werkstücken, bei denen eine Geräusch- oder Wärmedämmung erforderlich ist.In the context of the method according to the invention, it is also possible a workpiece made of material sheets from different plants to form fabrics. It can be advantageous here Material sheet to use, the material at a thermi effects a greater change in volume than that other material sheet. This can be for the production of Liquid containers or the like. Of importance or of Workpieces that require noise or thermal insulation is required.
Nachstehend ist die Erfindung anhand der Zeichnung an Ausfüh rungsbeispielen näher erläutert. Es zeigen: The invention is based on the drawing of Ausfüh tion examples explained in more detail. Show it:
Fig. 1a ein zweilagiges Werkstück vor dem Aufwölben, FIG. 1a is a two-ply workpiece prior to buckling,
Fig. 1b das Werkstück der Fig. 1a nach dem Aufwölben, FIG. 1b, the workpiece of FIG. 1 after the bulging,
Fig. 2 ein Fließbild zur Fertigung eines Werkstückes nach Fig. 1b und Fig. 2 is a flow chart for manufacturing a workpiece according to Fig. 1b and
Fig. 3 ein mehrlagiges Werkstück. Fig. 3 is a multi-layer workpiece.
Fig. 1a zeigt zwei aufeinanderliegende Werkstofftafeln 1 und 2, die an mehreren definierten Stellen 3 fest miteinander verbunden sind. Diese Verbindungen können punkt- oder linien förmige Schweiß- oder Klebestellen oder durch Rollbonding erzeugte bandförmige Verbindungsstellen sein. Fig. 1a shows two superposed material sheets 1 and 2 which are connected at several defined points 3 to each other. These connections can be point-shaped or line-shaped welding or gluing points or band-shaped connection points produced by roll bonding.
Dieses zweilagige Werkstück wird im Ausführungsbeispiel auf seiner Oberseite von außen mittels eines Behandlungsverfahrens zur Erzeugung von Aufwölbungen zwischen den Verbindungsstellen 3 beaufschlagt, was mit Pfeilen 4 bezeichnet ist.In the exemplary embodiment, this two-layer workpiece is acted upon from the outside on its upper side by means of a treatment method for producing bulges between the connection points 3 , which is indicated by arrows 4 .
Fig. 1b zeigt das Werkstück der Fig. 1a nach seiner Behandlung. Wie zu erkennen ist, haben sich die zwischen den Verbindungs stellen 3 befindlichen Teile der oberen Werkstofftafel 1 konvex nach oben gewölbt und bilden entsprechende beulenförmige Aufwölbungen 5, die zwischen den beiden Werkstofftafeln Luft einschließen. Fig. 1b shows the workpiece of Fig. 1a after its treatment. As can be seen, the parts of the upper material plate 1 located between the connection points 3 have a convex upward curvature and form corresponding bulge-shaped bulges 5 which enclose air between the two material plates.
Diese Aufwölbungen 5 können je nach der Art und Weise, wie die Verbindungsstellen 3 angeordnet und ausgeführt sind, eine unterschiedliche Gestalt, Flächenausdehnung und Ausrichtung haben. So können bei einer Punktrasteranordnung der Verbin dungsstellen 3 kreisförmige oder elliptische Aufwölbungen 5 gebildet werden, ggf. solche, deren Längsachse im Winkel zu den Reihen der Verbindungsstellen 3 steht.Depending on the way in which the connection points 3 are arranged and designed, these bulges 5 can have a different shape, surface area and orientation. Thus, the binding sites may Verbin 3 circular or elliptical bulges 5 are formed in a dot pattern arrangement if necessary, those whose longitudinal axis is at an angle to the rows of the joints. 3
Bei parallelen, linienförmigen Verbindungsstellen 3 können kanalförmige Aufwölbungen 5 gebildet werden, die, wenn sie aufgeschnitten sind, an Zuleitungen für flüssige oder gasförmi ge Medien anschließbar sind.In the case of parallel, line-shaped connection points 3 , channel-shaped bulges 5 can be formed, which, when cut open, can be connected to feed lines for liquid or gaseous media.
Ein wesentliches Merkmal ist bei allen diesen Erscheinungsfor men, daß das aus zwei Werkstofftafeln gebildete und erfindungs gemäß behandelte Werkstück eine beträchtliche Steifigkeit aufweist. Gleichzeitig ergibt sich gegenüber einem gleich steifen einlagigen Werkstück eine Gewichtsersparnis von etwa 40%.A key feature of all is this appearance men that formed from two sheets of material and fiction considerable rigidity according to the treated workpiece having. At the same time it results in an equal to one stiff single-layer workpiece a weight saving of about 40%.
Eine weitere Vergrößerung der Steifigkeit ergibt sich, wenn auch die untere Werkstofftafel 2 so wie die obere Werkstoffta fel 1 von außen behandelt wird.A further increase in the rigidity is obtained if the lower material sheet 2 is treated from the outside as is the upper material sheet 1 .
Fig. 2 zeigt den erfindungsgemäßen Verfahrensablauf an einem Fließbild. Von Coils 6, 7 werden je ein Werkstoffband 8, 9 aus dünnem, umformbarem Werkstoff, z. B. Metall oder Kunststoff abgezogen und an der Station 10 miteinander fest verbunden. Diese Verbindung kann durch Verschweißen, ggf. mit Laserstrah len, Verkleben oder Rollbonding erfolgen, wobei die Verbin dungswerkzeuge so ausgebildet und/oder geführt sind, daß die Verbindungsstellen nach einem bestimmten Muster bzw. Raster auf den Werkstoffbändern 8, 9 verteilt werden. Fig. 2 shows the method sequence according to the invention in a flow diagram. Coils 6 , 7 each have a material strip 8 , 9 made of thin, formable material, e.g. B. metal or plastic and firmly connected to each other at the station 10 . This connection can be made by welding, possibly with laser beams, gluing or roll bonding, the connec tion tools designed and / or guided so that the connection points are distributed according to a certain pattern or grid on the material strips 8 , 9 .
Das auf diese Weise hergestellte Twin- oder Mehrlagenband wird als Halbzeug zu einem Coil 11 aufgewickelt und kann an einem anderen Ort weiterbehandelt werden.The twin or multi-layer strip produced in this way is wound up as a semi-finished product to form a coil 11 and can be further processed at another location.
Dieses Coil 11 wird in einer weiteren Bearbeitungsstufe abgewickelt und in Tafeln 12 abgeteilt, die dann in einer Umformstation, z. B. Tiefziehpresse in die endgültige Form des Werkstückes 13 gebracht werden. Anschließend wird mindestens eine der beiden Seiten des Werkstückes 13 von außen so beaufschlagt 4, daß sich die oben erwähnten Auswölbungen 5 ausbilden. Dies erfolgt beispielsweise durch ein mechanisches Strahlverfahren (Sand- oder Kugelstrahlverfahren). Dabei wird der Werkstoff so verdrängt, daß sich eine Materialdehnung ergibt, die zu einer konvexen Aufwölbung führt.This coil 11 is processed in a further processing stage and divided into sheets 12 , which are then in a forming station, for. B. deep drawing press can be brought into the final shape of the workpiece 13 . Then at least one of the two sides of the workpiece 13 is acted upon 4 from the outside in such a way that the bulges 5 mentioned above form. This is done, for example, by a mechanical blasting process (sand or shot peening). The material is displaced in such a way that there is a material expansion which leads to a convex bulge.
Es ist auch möglich, je nach Art des verwendeten Werkstoffes eine thermische Beaufschlagung, ggf. auch in Verbindung mit einer Vakuumeinwirkung durchzuführen.It is also possible, depending on the type of material used thermal exposure, possibly also in connection with a vacuum.
Im Rahmen des Erfindungsgedankens ist es auch möglich, entsprechend Fig. 3 ein Werkstück aus mehr als zwei Werkstoffta feln 1, 2, 14, 15 herzustellen, wobei diese auch aus unterschied lichen Werkstoffen bestehen können. Auch hierbei können die Aufwölbungen 5 an einer oder bei den Seiten vorgesehen sein.Within the scope of the inventive concept, it is also possible, according to FIG. 3, to produce a workpiece from more than two material panels 1 , 2 , 14 , 15 , which may also consist of different materials. Here, too, the bulges 5 can be provided on one or on the sides.
