Description
Es ist bekannt, daß die moderne Schießtechnik Geschosse verwendet, deren Kern aus Wolfram oder Wolframlegierungen besteht, um eine größere Durchschlagskraft zu erzielen. Die Geschosse bestehen in der Regel aus dem Mantel aus Kupfernickel oder ähnlichem Material; der Zwischenlage aus Weichmetall, wie Blei u. dgl., und endlich aus dem Kern aus Wolfram oder Wolframlegierungen mit hohem Wolframgehalt. Die Anordnung einer Zwischenlage aus Weichmetall hat den Zweck, daß das Geschoß sich in die Züge des Gewehrlaufes einpressen kann und so die erforderliche Drehung zur Erzielung einer hohen Rasanz undIt is known that modern shooting technology uses projectiles whose core is made of Tungsten or tungsten alloys is made to achieve greater penetration. The projectiles usually consist of a jacket made of cupronickel or similar material; the intermediate layer made of soft metal, such as lead and the like, and finally from the core Tungsten or tungsten alloys with a high tungsten content. The arrangement of a liner made of soft metal has the purpose that the projectile is in the rifle barrel can press in and so the required rotation to achieve a high level of speed and
J5 Treffsicherheit erzielt wird. J 5 accuracy is achieved.
Es ist nun weiter bekannt, daß sich reines Wolfram infolge seiner außerordentlichen Härte schwer berarbeiten läßt (ζ. Β. beim Abdrehen in die gewünschte Geschoßform), so daß man deshalb die Geschosse aus weicheren Wolframlegierungen herstellt.It is now also known that pure tungsten, due to its extraordinary hardness difficult to rework (ζ. Β. when turning into the desired bullet shape), so that one that's why the bullets are made from softer tungsten alloys.
Gegenstand der Erfindung ist nun der Ersatz des bisher aus einer Metallegierung bestehenden Kernes durch einen solchen, welcher aus hartem, zähem Stahl, Eisen ο. dgl. hergestellt und mit reinem, hartem Wolframdraht ummantelt und verschweißt ist.The subject of the invention is the replacement of what was previously made of a metal alloy Core through one made of hard, tough steel, iron ο. Like. Manufactured and with pure, hard tungsten wire is sheathed and welded.
Es soll hierzu zweckmäßig der käuflich zu habende, außerordentlich härte Wolframdraht verwendet werden, der in einfacher Weise mit dicht nebeneinanderliegenden Windungen um einen zähen Stahlkern· gewickelt wird. Um die gewünschte Durchschlagskraft zu erhalten, muß der ungehärtete Stahl etwa folgende Eigenschaften aufweisen: 'For this purpose, the extraordinarily hard tungsten wire, which is commercially available, should expediently be used, which in a simple manner with closely spaced turns around a tough steel core · is wound. To get the desired impact, the unhardened steel must have approximately the following properties: '
Streckgrenze.. 6o kg
Bruchgrenze · · 75 kg
Dehnung i8 Prozent·Yield strength .. 6o kg
Breaking limit · · 75 kg
Elongation i8 percent
pro ι g.per ι g.
Der so erzielte Körper wird nun einer hohen Temperatur ausgesetzt, bis sich der zähflüssige Kern mit den Wolframwindungen innig verbunden hat. Auf diese Weise ist es möglich, ein wirklich widerstandsfähiges Geschoß zu erhalten, bei dem außerdem eine erhebliche Ersparnis an teurem Wolframmetall eintritt. Der Kern gemäß der Erfindung wird alsdann in der bekannten Weise zuerst mit Weichmetall und dann mit dem Kupfernickelmantel umhüllt, so daß ein Geschoß entsteht, wie es in der Figur dargestellt ist. Es bedeutet a der äußere Mantel aus Kupfernickel 0. dgl., b die Zwischenlage eines Weichmetalls und c der mit Wolframdraht ummantelte Kern.The body obtained in this way is now exposed to a high temperature until the viscous core has become intimately connected with the tungsten windings. In this way it is possible to obtain a really tough projectile with a considerable saving of expensive tungsten metal. The core according to the invention is then sheathed in the known manner first with soft metal and then with the copper-nickel jacket, so that a projectile is produced as shown in the figure. It means a the outer jacket made of cupronickel 0 or the like, b the intermediate layer of a soft metal and c the core encased with tungsten wire.
