Abstract
Description
Die Erfindung betritt eine Ubungspatrone für Handfeuerwaffen der im Oberbegriff des Anspruchs 1 angegebenen ArtThe invention enters a practice cartridge for handguns of the type specified in the preamble of claim 1
Für Handfeuerwaffen kennt man Übungsmunition mit einer aus Kunststoff hergestellten Hülse mit Geschoßnachbildung und einem in die Hülse eingesetzten Metallbodenstück mit Zündeinrichtung. Hierbei zeigt sich, daß in heißgeschossenen Waffen das Kunststoffmaterial nicht die erforderliche Standfestigkeit.besitzt, um ein absolut sicheres und störungsfreies Schießen zu gewährleisten. Es wurde daher auch schon vorgeschlagen, ebenso wie beim scharfen Schuß die Hülse mit Geschoßnachbildung aus Buntmetall herzustellen. Abgesehen von den für den Einsatz als Übungsmunition zu hohen Kosten des Buntmetalles hat dieses den Nachteil, daß es nicht immer in der erforderlichen Menge zur Verfügung steht bzw. mit Sichexheit zur Verfügung stehen wird.For small arms, practice ammunition is known with a case made of plastic with a projectile replica and a metal base piece with an ignition device inserted into the case. This shows that in hot-shot weapons the plastic material does not have the necessary stability to ensure absolutely safe and trouble-free shooting. It has therefore already been proposed to produce the sleeve with bullet replication from non-ferrous metal, just as with the sharp shot. Apart from the high cost of the non-ferrous metal for use as practice ammunition, this has the disadvantage that it is not always available in the required amount or will be available with certainty.
Die Erfindung macht es sich daher zur Aufgabe, eine Übungspatrone zu schaffen, die einerseits allen an sie gestellten technischen Anforderungen gerecht wird, andererseits aber preiswert und insbesondere jederzeit unbegrenzt ohne Materialbeschaffungsprobleme herstellbar ist. Erfindungsgemäß wird dies mit einer Übungspatrone entsprechend dem Kennzeichen des Anspruchs 1 erreicht, nämlich durch die Herstellung der Hülse mit Geschossnachbildung aus einem Stahlrohrstück. Die Erfindung macht also in nicht naheliegender und vorteilhafter Weis Gebrauch von einer Ausführungsform für die Hülse mit Geschoßnachbildung, wie sie sich unter Verwendung von Kunststoff im Wege des Spritzgußverfahrens verhältnismäßig leicht und einfach realisieren läßt, bei Verwendung von Stahl als Hülsenwerkstoff aber überraschend ist, da die physikalischen Voraussetzungen bei diesem Material völlig andere sind als bei Kunststoff, und naturgemäß bei der Komplettierung der Teile zur fertigen Patrone andere Probleme anstehen als bei einer Kunststoffhülse.The invention therefore makes it its task to create a training cartridge which on the one hand meets all the technical requirements placed on it, but on the other hand is inexpensive and in particular can be produced at any time without any problems in terms of material procurement. According to the invention, this is achieved with an exercise cartridge according to the characterizing part of claim 1, namely by producing the sleeve with projectile replica from a piece of steel tube. The invention thus makes use of an embodiment for the sleeve with projectile replica in a manner which is not obvious and advantageous, as can be implemented relatively easily and simply using plastic by means of the injection molding process, but is surprising when using steel as the sleeve material, since the The physical requirements for this material are completely different to those for plastic, and naturally there are other problems with the completion of the parts to the finished cartridge than with a plastic sleeve.
Nach einem Vorschlag der Erfindung wird das Stahlrohrstück durch Zieh- und/oder Preßvorgänge auf die erforderlichen Wanddickenabmessungen und in die Hülsenform mit Geschoßnachbildung gebracht sowie an seinem einen Ende mit einem patronengerechten dichten Verschluß versehen, wofür die bekannten Verschlußarten wie Stern-, Falt-, Präge- oder Bördelverschluß in Frage kommen.According to a proposal of the invention, the tubular steel piece is brought to the required wall thickness dimensions and into the sleeve shape with projectile simulation by drawing and / or pressing operations and is provided at one end with a cartridge-compatible tight closure, for which the known types of closure such as star, folding, embossing - or flare closure come into question.
Nach dem Befüllen der Hülse mit Geschoßnachbildung mittels des Treibladungspulvers und dem Einsetzen des Bodenstückes, das wie üblich die Zündeinrichtungen enthält, in das offene Hülsenende, werden diese beiden Teile mittels einer Rillung, Sickung oder dgl. mit wenigstens einer Rille bzw. Sicke rundum form- und kraftschlüssig miteinander verbunden, so daß die erforderliche Gasdichtigkeit gegeben ist. Dazu erweist es sich als zweckmäßig, zur Verbesserung der Dichtigkeit und Liderung die Verbindungszone zumindest der Hülseninnenseite, vorteilhaft aber-auch der Bodenstückaußenseite,mit einem Dichtungsmaterial, beispielsweise einem Bitumenlack, zu versehen.After filling the sleeve with projectile replica by means of the propellant charge powder and inserting the base piece, which contains the ignition devices as usual, into the open sleeve end, these two parts are shaped by means of a grooving, beading or the like with at least one groove or bead all around. and non-positive interconnected so that the required gas tightness is given. For this purpose, it has proven expedient to provide the connection zone at least on the inside of the sleeve, but advantageously also on the outside of the base piece, with a sealing material, for example a bitumen varnish, in order to improve the tightness and sealing.
Im Hinblick auf die durch die Verwendung von Stahl als Material für die Hülse mit Geschoßnachbildung sich ergebenden besonderen Probleme bezüglich der Liderung wird weiterhin vorgeschlagen, Hülse und Bodenstück auf einer Länge miteinander zu verbinden, die mindestens so groß ist wie der Innendurchmesser der Hülse im Bereich des Bodenstückes, und wobei das Bodenstück auf zumindest nahe zu der ganzen Länge der Verbindungszone als Liderungszone ausgebildet ist, vorzugsweise durch eine näpfchenförmige Gestaltung mit nach dem offenen Ende zu kontinuierlich abnehmender Wanddicke.In view of the particular problems with respect to the eyelid caused by the use of steel as a material for the sleeve with a projectile replica, it is further proposed to connect the sleeve and base piece to one another over a length which is at least as large as the inner diameter of the sleeve in the region of Bottom piece, and wherein the bottom piece is formed on at least close to the entire length of the connection zone as a eyelid zone, preferably by a cup-shaped design with a continuously decreasing wall thickness after the open end.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel gezeigt und wird anhand dieses nachstehend erläutert.The invention is shown in the drawing in an embodiment and is explained below with reference to this.
In der Hülse 1 mit Geschoßnachbildung 2 ist am hinteren Ende das Bodenstück 3 mit Anzündhütchen 4 und Zündkanal 5 eingesetzt. Das vordere Ende der Hülse bzw. der Geschoßnachbildung ist mittels des Faltverschlusses 6 dicht verschlossen. Mit 7 ist die Treibpulverladung bezeichnet.In the sleeve 1 with
Da die Hülse 1 mit Geschoßnachbildung-2 mittels des Faltverschlusses 6 bereits bei ihrer Herstellung bzw. Formgebung aus einem Rohrstück im Bereich der Geschoßnachbildung 2 dicht verschlossen wird, wird beim Herstellen der kompletten Patrone zunächst vom offenen hinteren Ende her das Treibladungspulver in die Hülse einge füllt, dann das Bodenstück 3 mit Zündeinrichtung eingesetzt und schließlich beide Teile durch einen Würge-, Kneif- oder Rillungsvorgang mit wenigstens einer sich über den ganzen Umfang erstreckenden Rille, Sicke oder dgl. 8 versehen, um die erforderliche Gasdichtigkeit zu erzielen. Ggf. kann zwecks Verbesserung der Dichtwirkung die Verbindungszone des einen und/oder des anderen Teiles an den benachbarten Flächen mit einem Auftrag einer Dichtungsmasse, beispielsweise einem Bitumenlack, versehen werden. Im Sinne der Erzielung einer guten Liderung ist die Länge der Verbindungszone zwischen Hülse 1 und Bodenstück 3 wenigstens so groß wie der Innendurchmesser der Hülse ausgeführt und ist der im wesentlichen axiale hülsenförmige Teil des Bodenstückes mit nach seinem freien Ende zu abnehmender Wanddicke ausgebildet.Since the sleeve 1 with
Es versteht sich, daß sowdil. die Zahl der Rillen als auch deren Form ebenso wie die Formgebung des Bodenstückes in vielerlei Weise variiert werden kann, und daß es auch möglich ist, durch entsprechende Vorbehandlung, insbesondere auch Oberflächenbehandlung von Hülse mit Geschoßnachbildung sowie Bodenstück Effekte im Sinne einer bestmöglichen Qualität und Eignung der erfindungsgemäßen Patrone zu erzielen.It goes without saying that sowdil. the number of grooves and their shape as well as the shape of the base piece can be varied in many ways, and that it is also possible to effect the best possible quality and suitability by appropriate pretreatment, in particular surface treatment of sleeve with projectile replica and base piece effects to achieve cartridge according to the invention.
