Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer Übungspatrone für Handfeuerwaffen der im Oberbegriff des Anspruchs angegebenen Art.The invention relates to a method for producing a training cartridge for handguns of the type specified in the preamble of the claim.
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 Sicherheit 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 in the case of a 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 certainly be available.
Es ist weiterhin aus der DE-B-1 082 162 eine Platzpatrone aus z.B. Stahl bekannt, bei welcher die zugefalzte Geschoßnachbildung den einzigen Abschluß für die Pulverladung darstellt. Die Zufalzung wird erst nach Einbringung der Pulverladung vorgenommen. Das bedeutet aber, daß es sich hier um eine Stahlhülse handelt, bei der das Bodenstück einstückig angeformt und die aus einer massiven Ronde hergestellt ist. Selbst wenn zwischen den dabei erforderlichen zahlreichen Umformungsschritten jeweils Zwischenglühungen vorgesehen sind, stellt das nachträgliche Verschließen der Geschoßnachbildung hierbei eine kritische Maßnahme dar, so daß nicht immer das geforderte splitterfreie Öffnen gewährleistet ist.Furthermore, DE-B-1 082 162 is a blank cartridge from e.g. Steel is known in which the folded-up projectile replica is the only termination for the powder load. Folding is only carried out after the powder charge has been introduced. However, this means that this is a steel sleeve in which the base piece is integrally formed and which is made from a solid blank. Even if intermediate annealing is provided between the numerous forming steps required, the subsequent closing of the projectile replica is a critical measure, so that the required splinter-free opening is not always guaranteed.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung einer Übungspatrone der im Oberbegriff des Anspruchs angegebenen Art anzugeben, mit dem es möglich ist, eine Übungspatrone herzustellen, die einerseits allen an sie gestellten technischen Anforderungen gerecht wird, andererseits aber preiswert und insbesonder jederzeit unbegrenzt ohne Materialbeschaffungsprobleme herstellbar ist.The invention has for its object to provide a method for producing a training cartridge of the type specified in the preamble of the claim, with which it is possible to produce a training cartridge that on the one hand meets all the technical requirements placed on it, but on the other hand inexpensive and in particular unlimited at all times can be produced without material procurement problems.
Erfindungsgemäß wird dies mit einem Verfahren entsprechend dem Kennzeichen des Anspruchs erreicht. Die Erfindung macht dabei in nicht naheliegender und vorteilhafter Weise 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. Nach 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 the invention this is achieved with a method according to the characterizing part of the claim. The invention makes not obvious and advantageous use of an embodiment for the sleeve with projectile replica, as it can be realized 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 from those for plastic, and naturally there are other problems with the completion of the parts for the finished cartridge than with a plastic sleeve. According to the invention, the steel tube piece is brought to the required wall thickness dimensions and into the sleeve shape with projectile replication by drawing and / or pressing operations and 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-positively connected 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 lacquer, in order to improve the tightness and lids.
Im Hinblick auf die durch die Verwendung von Stahl als Material für die Hülse mit Geschoßnachbildung sich ergebenden besonderen Probleme bezüglich der Liderung kann weiterhin vorgesehen werden, 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 nahezu 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 that result from the use of steel as the material for the sleeve with a projectile replica, provision can further be made for the sleeve and base piece to be connected to one another over a length which is at least as large as the inner diameter of the sleeve in the region of the base piece, and wherein the base piece is designed as a lidging zone over at least almost the entire length of the connecting zone, preferably by a cup-shaped design with a wall thickness that decreases continuously after the open end.
Eine nach dem erfindungsgemäßen Verfahren hergestellte beispielhafte Übungspatrone ist in der Zeichnung gezeigt, an der das Verfahren noch näher erläutert wird.An exemplary exercise cartridge produced by the method according to the invention is shown in the drawing, on which the method is explained in more detail.
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 eingefüllt, 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. Gegebenenfalls 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 sowohl 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 is understood that both 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 in the sense of appropriate pretreatment, in particular also surface treatment of sleeve with projectile replica and base piece effects to achieve the best possible quality and suitability of the cartridge according to the invention.
