Description
Die Erfindung betrifft die Verwendung von Eisen oder vorzugsweise Kupfer als Werkstoff für die Herstellung metallischer grobkörniger Auskleidungen von Hohlladungen.The invention relates to the use of iron or preferably copper as a material for manufacture metallic coarse-grained lining of shaped charges.
Metallische Auskleidungen von Hohlladungen werden entweder in geglühtem oder in nicht geglühtem Zustand verwendet. In beiden Fällen weist das Gefüge des Metalls üblicherweise eine sehr geringe Korngröße in der Größenordnung von 6 bis 8 Indiges des AFNOR-Systems auf. d.h. eine Korngröße unterhalb von 50 bis 60 μ. So sind aus der französichen Patentschrift 1057 294 Auskleidungen für Hohlladungen bekannt, welche aus Kupfer oder aus einer einen Zusatz enthaltenden Zweistoff legierung bestehen; die Korngröße dieser Auskleidungen liegt im Bereich von 20 bis 30 μ.Metallic linings of shaped charges are either annealed or not Used condition. In both cases, the structure of the metal usually has a very small grain size in the order of 6 to 8 indiges of the AFNOR system. i.e. a grain size below from 50 to 60 μ. For example, French patent specification 1057 294 discloses linings for shaped charges known, which are made of copper or a two-component alloy containing an additive; the The grain size of these linings is in the range from 20 to 30 μ.
Die durch Schmieden oder Tiefziehen und anschließende Bearbeitung hergestellten Auskleidungen aus Kupfer werden im allgemeinen geglüht, um die Wirkungen der Kaltverformung wenigstens zum Teil zu beseitigen. Die Größe der Gefügekörner entspricht üblicherweise dem AFNOR-Index 6, d. h., ihre mittleren Abmessungen betragen etwa 40 bis 50 μ. Die Glühbehandlung, welche zu diesem Ergebnis führt und welche bei jedem Metall anders verläuft, wird im allgemeinen bei einer Temperatur von etwa 550° C etwa 20 bis 30 Minuten lang durchgeführt.The linings produced by forging or deep drawing and subsequent machining Copper is generally annealed to at least partially reduce the effects of cold working to eliminate. The size of the grains usually corresponds to the AFNOR index 6, i.e. i.e., their middle ones Dimensions are around 40 to 50 μ. The annealing treatment that leads to this result and which is different for each metal, is generally at a temperature of about 550 ° C performed for about 20 to 30 minutes.
Für Hohlladungen bekannte Auskleidungen aus reinem Eisen werden ebenfalls im allgemeinen im kaltgehärteten Zustand verwendet. Ihr Gefüge ist im wesentlichen das gleiche wie dasjenige des Kupfers.Linings made of pure iron known for shaped charges are also generally used in the cold-hardened state. Their structure is in essentially the same as that of copper.
Gegenüber Auskleidungen der bekannten Art besteht die Aufgabe der vorliegenden Erfindung darin, einen für Auskleidungen geeigneten Werkstoff zu schaffen, durch welchen die Leistung der Hohlladungen erheblich gesteigert werden kann und durch welchen der Treibstrahl regelbar ist.Compared to linings of the known type, the object of the present invention is to To create a material suitable for linings, through which the performance of the shaped charges can be increased considerably and through which the propulsion jet can be regulated.
Diese Aufgabe wird erfindungsgemäß gelöst durch Verwendung von bei 600 bis 700° C oder mehr mindestens 1 Stunde bis auf eine Korngröße von 60 bis 250 μ, vorzugsweise 100 bis 200 μ, geglühtem Eisen oder vorzugsweise Kupfer als Werkstoff für die Herstellung metallischer Auskleidungen von Hohlladungen, die entsprechend grobkörnig sein müssen.According to the invention, this object is achieved by using at least 600 to 700 ° C. or more 1 hour down to a grain size of 60 to 250 μ, preferably 100 to 200 μ, of annealed iron or preferably copper as a material for the production of metallic linings for shaped charges, which must be correspondingly coarse-grained.
Es können auch Körner mit einer Größe von 180 bis 250 μ, entsprechend dem AFNOR-Index 1 oder 2, oder von 60 μ, entsprechend dem AFNOR-Index 5, verwendet werden.Grains with a size of 180 to 250 μ, corresponding to the AFNOR index 1 or 2, can also be used. or of 60 μ, corresponding to the AFNOR index 5, can be used.
Durch Verwendung von Werkstoffen der genannten Art konnte in der Tat eine wirkliche Leistungssteigerung der Hohlladungen und eine gleichmäßige Führung des Treibstrahles erzielt werden.By using materials of the type mentioned, a real increase in performance could indeed be achieved the shaped charges and a uniform guidance of the propulsion jet can be achieved.
Gefügekörner dieser Größenordnung können durch bekannte Verfahren, insbesondere durch zweckentsprechende Wahl des Bereiches der mechanischen Bearbeitung der Auskleidung vorbereitet (als Halbprodukt, Streifen, Ziehplatine, Verformung durch Tiefziehen oder Schmieden, Bearbeitung usw.) und durch eine abschließende Glühbehandlung, welche die wesentliche Rolle für die Ausbildung des grobkörnigen Gefüges des die Auskleidung bildenden Metalls spielt, erzeugt werden.Structural grains of this size can through known processes, in particular through appropriate selection of the mechanical range Processing of the lining prepared (as a semi-finished product, strip, drawing plate, deformation by Deep drawing or forging, machining, etc.) and a final annealing treatment, which the essential role for the formation of the coarse-grained structure of the metal forming the lining plays are generated.
