Abstract
Description
Die Erfindung beschreibt ein dreidimensional geformtes Bauteil aus einer Stahlplatine zur Panzerung eines Fahrzeugs.The invention describes a three-dimensionally shaped component made of a steel plate for arming a vehicle.
Fahrzeuge werden derzeit gegen Beschuss mit Bauteilen aus Stahl gepanzert (ballistischer Schutz), indem zunächst eine spezielle Panzerstahlsorte ausgewählt wird. Panzerstähle sind niedrig legierte Vergütungsstähle mit einer hohen Härte.Vehicles are currently being armored against steel bombardment (ballistic protection) by first selecting a particular type of steel armor. Armored steels are low-alloy tempered steels with a high hardness.
Aus der
In Abhängigkeit von der Vergütung des Stahls lässt sich entweder eine hohe Festigkeit des Stahls auf Kosten der Duktilität oder eine zum Energieverzehr hinreichende Duktilität bei allerdings verringerter Härte einstellen. Müssen Werkstücke aus Panzerstahlblechen verformt, insbesondere gebogen werden, so werden relativ aufwändige Biegeverfahren und Biegewerkzeuge benötigt. Dennoch lassen sich herkömmliche Panzerstahlbleche nur bedingt und mit geringfügigen Formänderungen spanlos bearbeiten, insbesondere biegen (bis max. 4°), ohne zu brechen bzw. Oberflächenrisse zu zeigen. Aufgrund dieser Probleme wird eine Panzerung in der Regel aus vielen kleinen Stücken aufgebaut, die miteinander verschweißt werden, um eine komplexe Form abzubilden. Beim Schweißen der Panzerstahlwerkstoffe sinkt die Härte im Bereich der Wärmeeinflusszone stark ab. Um dennoch den Schutz gegen Geschosse durch die Panzerung zu gewährleisten, werden zum Beispiel weitere Panzerstahlplatten im Bereich der Schweißnähte überlappend angeordnet. Alternativ werden die Schweißnähte beispielsweise rückseitig mit Aramidlayern hinterlegt. Der Einbau einer von außen nicht sichtbaren Panzerung ist daher insgesamt bauraumintensiv. Durch den Verlust an Bauraum kann es zu Einschränkungen wichtiger Funktionalitäten des Fahrzeugs kommen, wenn diese nicht mehr untergebracht werden können. Ein Beispiel hierfür ist bei zivilen Fahrzeugen der Einbau von Seiten- und Kopfairbags.Depending on the tempering of the steel, either a high strength of the steel at the expense of ductility or a ductility sufficient for energy consumption can be set with a reduced hardness. If workpieces of armor steel sheets have to be deformed, in particular bent, relatively complicated bending processes and bending tools are required. Nevertheless, conventional armor steel sheets can be machined only conditionally and with minor changes in shape, in particular bending (up to a maximum of 4 °), without breaking or showing surface cracks. Because of these problems, armor is usually built up from many small pieces that are welded together to form one depict complex form. When welding the armor steel materials, the hardness in the area of the heat affected zone drops sharply. Nevertheless, to ensure protection against projectiles by the armor, for example, further armor steel plates are arranged overlapping in the welds. Alternatively, the welds are deposited, for example, on the back with Aramidlayern. The installation of an externally invisible armor is therefore space-consuming. The loss of space can lead to restrictions of important functionalities of the vehicle if they can no longer be accommodated. An example of this is the installation of side and head airbags on civilian vehicles.
Eine besondere Problemstellung bilden Radien. In Radien oder Biegungen zeigt der ballistische Schutz ein im Vergleich zu ebenen Flächen abweichendes Verhalten. Bei gleichbleibender Blechstärke kommt es aufgrund der geometrischen Form zu einer Schwächung gegen Beschuss. Beispielsweise kann es zu Durchschüssen oder Rissen kommen. In den Radien ist die Blechstärke daher zu gering und deswegen unterdimensioniert. Folglich werden Panzerungen in Radien oder Biegungen extra verstärkt. Dies kann beispielsweise durch sogenannte Backings geschehen. Backings sind aus metallischen oder nichtmetallischen Werkstoffen aufgebaute, im Regelfall durch Kleben aufgebrachte Verstärkungen. Die Unsicherheit der zuverlässigen adhesiven Wirkung des Klebstoffes insbesondere unter Zeiteinwirkung, das Auftreten von Bauteilkorrosion und die passgenaue Fixierung der Backings sind problematisch. Hinzu kommen Werkzeugkosten zur Herstellung der Backings. Alternativ kann die Wandstärke des gesamten Panzerungsteils homogen auf die zu erzielende Schutzwirkung in den Radien ausgelegt werden, um Durchschüsse oder Risse zu vermeiden. Dadurch ist das Formbauteil in den ebenen Flächen jedoch für die zu erzielende Schutzwirkung zu dick und damit überdimensioniert und insgesamt zu schwer und zu teuer.A particular problem is formed by radii. In radii or bends, ballistic protection shows a behavior that differs from flat surfaces. At constant sheet thickness occurs due to the geometric shape to a weakening against bombardment. For example, bullet holes or cracks can occur. In the radii, the sheet thickness is therefore too low and therefore undersized. As a result, armor in bends or bends will be extra reinforced. This can be done for example by so-called backings. Backings are made of metallic or non-metallic materials, usually applied by gluing reinforcements. The uncertainty of the reliable adhesives effect of the adhesive, in particular under the effect of time, the occurrence of component corrosion and the precise fixing of the backings are problematic. In addition there are tool costs for the production of the backings. Alternatively, the wall thickness of the entire armor part can be designed homogeneously to the protective effect to be achieved in the radii in order to avoid bullet holes or cracks. As a result, however, the molded component in the flat surfaces is too thick for the protective effect to be achieved, and thus oversized, and altogether too heavy and too expensive.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, ein dreidimensional geformtes Panzerungsbauteil aufzuzeigen, dass verbesserte ballistische Eigenschaften aufweist.Based on this prior art, it is an object of the invention to show a three-dimensionally shaped armor component that has improved ballistic properties.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst, indem ein dreidimensional geformtes Bauteil zur Panzerung eines Fahrzeugs eingesetzt wird, bei dem die Ausgangsstahlplatine in einen Bereich mit verminderter und in einen Bereich mit erhöhter Wandstärke unterteilt ist. Das Bauteil ist dabei so ausgelegt, dass der Bereich mit erhöhter Wandstärke im Bereich eines Biegewinkels oder Radius des dreidimensionalen Bauteils liegt. Alternativ oder zusätzlich kann in einem Bereich des Bauteils, der nach dem Einbau in das Fahrzeug ausschließlich in einem Winkel ungleich 90° von einem Geschoss getroffen wird, die Wandstärke vermindert sein, weil in diesem Fall durch das schräge Auftreffen auf das Panzerungsbauteil mehr Weg durch die Wand des Bauteils zur Verfügung steht, bevor das Geschoss das Bauteil durchschlägt. Ebenso kann die Wandstärke in einem Bereich des dreidimensional geformten Bauteils vermindert sein, der nach dem Einbau in das Fahrzeug von einem anderen Bauteil überdeckt wird.This object is achieved with the features of
In einer Ausführungsform wird die Stahlplatine durch ein partielles Walzen in einen Bereich mit verminderter und in einen Bereich mit erhöhter Wandstärke unterteilt. Alternativ wird die Stahlplatine durch ein Fügen von verschiedenen Stahlblechen mit unterschiedlichen Wanddicken in einen Bereich mit verminderter und in einen Bereich mit erhöhter Wandstärke unterteilt. In einer weiteren Ausführungsform ist die Stahlplatine durch ein Fügen von verschiedenen Stahlblechen mit unterschiedlichen Legierungsbestandteilen in einen Bereich mit verminderter und in einen Bereich mit erhöhter Wandstärke unterteilt. In einer weiteren Alternative ist die Stahlplatine durch eine spanende Bearbeitung in einen Bereich mit verminderter und in einen Bereich mit erhöhter Wandstärke unterteilt.In one embodiment, the steel plate is divided by a partial rolling in a region with reduced and in an area with increased wall thickness. Alternatively, the steel plate is divided by joining different steel sheets with different wall thicknesses in a region with reduced and in an area with increased wall thickness. In a further embodiment, the steel plate is divided by joining different steel sheets with different alloying components in a region with reduced and in an area with increased wall thickness. In a further alternative, the steel plate is divided by machining into a region with reduced and in an area with increased wall thickness.
Besonders vorteilhaft ist das Bauteil warmgeformt und pressgehärtet, weil sich so eine größere maßgenaue Formgebung erzielen lässt als bei kalt geformten Bauteilen. Bei relativ niedrigen Sicherheitsanforderungen und damit verbundenen relativ geringen Blechstärken wie beispielsweise bei der Panzerung eines Fahrzeugs gegen Pistolenschüsse ist jedoch auch ein Kaltformen der maßgeschneiderten Platine möglich. Entscheidend ist jeweils, dass die bereits in der Platine vorliegende erhöhte Wandstärke während des Formprozesses so in das Umformwerkzeug eingelegt wird, dass die erhöhte Blechstärke im endgeformten Bauteil im Bereich der Radien und Biegewinkel liegt und/ oder die Bereiche mit verminderter Wandstärke in den geringer belasteten Bereichen liegen. Durch den erfindungsgemäßen Einsatz einer maßgeschneiderten Platine entfallen die Werkzeugkosten für das dreidimensionale Backing. Die erfindungsgemäße Lösung ist ballistisch sicherer als die Verklebung eines Backings, weil der Klebstoff eliminiert ist und mangels Spalten die Korrosionsgefahr entfällt. Außerdem ist das Bauteilgewicht gegenüber herkömmlichen Lösungen geringer.Particularly advantageously, the component is thermoformed and press-hardened, because a larger dimensionally accurate shape can be achieved than with cold-formed components. At relatively low safety requirements and associated relatively low sheet thicknesses such as the armor of a vehicle against pistol shots, however, a cold forming of the custom-made board is possible. It is crucial in each case that already present in the board increased wall thickness is inserted during the molding process in the forming tool that the increased sheet thickness in the final molded component in the radius and bending angle and / or the areas with reduced wall thickness in the less loaded areas lie. The use of a custom-made board according to the invention eliminates the tooling costs for three-dimensional backing. The solution according to the invention is ballistically safer than the bonding of a backing, because the adhesive is eliminated and the lack of corrosion eliminates the need for gaps. In addition, the component weight is lower compared to conventional solutions.
Es können so Panzerungen hergestellt werden, die der Endkontur der zu panzernden Fahrzeugstelle entsprechen und eine unterschiedliche auf die jeweilige Geometrie des Fahrzeugbauteils abgestimmte Wandstärke aufweisen. Dabei lassen sich vor allem auch Biegewinkel > 4° problemlos einstellen. Während des Tiefziehens und/ oder Biegens sind Biegewinkel bis zu 90° realisierbar. Es können sogar Strukturbauteile selbst aus Panzerstahl hergestellt werden, wodurch bei diesen Strukturteilen wie beispielsweise einer B-Säule oder auch einer komplett tiefgezogenen Tür keine zusätzliche Panzerung nötig ist. Es besteht daher die Möglichkeit, viele kleine miteinander verschweißte Einzelteile auch im Bereich von Radien und Biegewinkeln durch ein einzelnes Bauteil zu ersetzen. Dies verringert die Zahl der Schweißnähte und das damit verbundene Sicherheitsrisiko sowie den Aufwand, das Sicherheitsrisiko wiederum zu minimieren. Das einzelne Bauteil zeichnet sich durch eine hohe Genauigkeit und ein optimiertes Gewicht aus. Es lässt sich problemlos mit anderen Komponenten im Fahrzeug fügen.As armor can be made, which correspond to the final contour of the vehicle body to be armored and have a different tuned to the particular geometry of the vehicle component wall thickness. You can pretend everything also bending angle> 4 ° easily adjust. During deep drawing and / or bending bending angles up to 90 ° can be realized. It can even be made of armor steel structural components even, which in these structural parts such as a B-pillar or a completely deep-drawn door no additional armor is needed. It is therefore possible to replace many small parts welded together in the range of radii and bending angles by a single component. This reduces the number of welds and the associated security risk and the effort to minimize the security risk again. The single component is characterized by a high accuracy and an optimized weight. It fits easily with other components in the vehicle.
Das erfindungsgemäße sicherheits- und gewichtsoptimierte Bauteil aus einer maßgeschneiderten Platine ist gedacht für die Panzerung von Kraftfahrzeugen wie zum Beispiel gepanzerte Personenkraftwagen, insbesondere indem reguläre Karosseriebauteile durch gepanzerte Karosseriebauteile ersetzt werden. Die Erfindung ist hierauf jedoch nicht beschränkt. Auch beispielsweise Schützenpanzer und militärische Transportfahrzeuge können mit Blechdicken um die 12 mm problemlos erfindungsgemäß gepanzert werden. Bei Kampfpanzern wie dem Leopard können ebenfalls sicherheits- und gewichtsoptimierte Bauteile aus einer maßgeschneiderten Platine im Sinne der Erfindung zum Einsatz kommen. Üblicherweise werden diese Bauteile wegen der großen Wandstärken dann aber eher nur Teil einer Panzerung sein und nicht die gesamte Panzerung darstellen.The safety and weight-optimized component of a custom-made board according to the invention is intended for the armoring of motor vehicles such as, for example, armored passenger cars, in particular by replacing regular body components with armored body components. However, the invention is not limited thereto. Also, for example, armored personnel carriers and military transport vehicles can be armored easily with sheet thicknesses around 12 mm according to the invention. In battle tanks such as the Leopard can also safety and weight-optimized components from a custom board in the context of the invention are used.
