Description

Die Erfindung betrifft ein mechanisches Initiiersystem für hülsenlose Munition gemäß dem Oberbegriff des Anspruches 1.The invention relates to a mechanical initiation system for caseless ammunition according to the preamble of claim 1.

Aus der DE 21 05 295 C1 ist ein Pulverkörper für hülsenlose Munition, insbesondere für automatisch schießende Waffen, bekannt, der aus mindestens zwei Presslingen besteht, von welchen einer als Widerlager für das Zündmittel dient. Diese bekannte Munition wird mittels eines schlagempfindlichen Zündsatzes initiiert. Gekennzeichnet ist dieser bekannte Pulverkörper durch einen topfförmigen Pulverkörper-Pressling, auf dessen Topfboden das Zündmittel hohlraumseitig vorgesehen ist. Der topfförmige Pulverkörper-Pressling deckt einen ambossartigen Treibladungs-Pressling ab, der für das Zündmittel als Widerlager dient. Der topfförmige Pulverkörper-Pressling und der ambossartige Treibladungs-Pressling sind miteinander vorzugsweise durch eine Verklebung verbunden. Der in dieser Druckschrift beschriebene Schlagbolzen zur Initiierung des beschriebenen Pulverkörpers ist in einem Durchgangsloch eines Verschlusses mit Führungsteil angeordnet. Zum Anstechen d.h. Initiieren des Pulverkörpers d.h. der hülsenlosen Munition, muss der Schlagbolzen zwei Funktionen erfüllen:

  1. 1. Die Spitze des Schlagbolzens muss in den Pulverkörper eindringen und durch Schlag bzw. Reibung das Zündmittel initiieren;
  2. 2. der Schlagbolzen muss das Durchgangsloch, in dem er axial verstellbar ist, nach der Zündung gegen den hohen Gasdruck der heißen Pulvergase abdichten. Zu diesem Zwecke verdeutlicht die oben genannte DE 21 05 295 C1 schematisch eine Ringdichtung bzw. eine genaue Passung zwischen dem Schlagbolzen und der Wandung des Durchgangsloches. Es hat sich jedoch gezeigt, dass eine solche genaue Passung nicht ausreichend ist.
From the DE 21 05 295 C1 is a powder body for caseless ammunition, in particular for automatic firing weapons, known, which consists of at least two compacts, one of which serves as an abutment for the ignition means. This known ammunition is initiated by means of a shock-sensitive ignition set. This known powder body is characterized by a cup-shaped powder-body compact, on whose bottom of the pot the ignition means is provided on the cavity side. The cup-shaped powder body compact covers an anvil-like propellant compact, which serves as an abutment for the ignition. The pot-shaped powder body compact and the anvil-like propellant compact are preferably connected to each other by a bond. The firing pin described in this document for initiating the described powder body is arranged in a through hole of a closure with guide part. For piercing ie initiating the powder body ie the caseless ammunition, the firing pin must fulfill two functions:
  1. 1. The tip of the firing pin must penetrate into the powder body and initiate the ignition means by impact or friction;
  2. 2. The firing pin must seal the through hole, in which it is axially adjustable, after ignition against the high gas pressure of the hot powder gases. For this purpose, the above-mentioned DE 21 05 295 C1 schematically a ring seal or an exact fit between the firing pin and the wall of the through hole. However, it has been found that such an exact fit is not sufficient.

Aus der DE 2405762 A1 , welche eine Grundlage für den Oberbegriff des Anspruches 1 bildet, ist ein mechanisches lnitiiersystem für hülsenlose Munition bekannt, dessen Schlagbolzen treibladungskammerseitig mit einer ringförmigen Dichtlippe versehen ist. Diese Dichtlippe führt bei Gasdruckeinwirkung aus der Treibladungskammer durch elastische Aufweitung zur einer innigen Berührung mit der Innenwandung des Durchgangsloches für den Schlagbolzen. Dadurch wird das Durchgangsloch für den Schlagbolzen bei Zündung eines Pulverkörpers in der Treibladungskammer nach rückwärts abgedichtet. Die Dichtlippe wird bei Zünden des in der Treibladungskammer befindlichen Pulverkörpers direkt von den heißen, auf hohe Geschwindigkeiten beschleunigten Verbrennungsrückständen und Zündmittelteilen beaufschlagt. Dies führt nach einer gewissen Anzahl von Zündungsvorgängen zu einer stetig voranschreitenden Erosion der Dichtungslippe.From the DE 2405762 A1 , which forms a basis for the preamble of claim 1, a mechanical lnitiiersystem for caseless ammunition is known, the firing pin is provided treibladungskammerseitig with an annular sealing lip. This sealing lip leads at gas pressure from the propellant charge chamber by elastic expansion to an intimate contact with the inner wall of the through hole for the firing pin. As a result, the passage hole for the striker is sealed backward upon ignition of a powder body in the propellant charge chamber. The sealing lip is acted upon when igniting the powder body located in the propellant charge chamber directly from the hot, accelerated to high speeds combustion residues and Zündmittelteilen. This leads after a certain number of ignition processes to a steadily progressing erosion of the sealing lip.

Der Erfindung liegt die Aufgabe zugrunde, ein Initiiersystem der eingangs genannten Art zu schaffen, wobei mit einfachen Mitteln eine zuverlässige Abdichtung des Schlagbolzens in dem für ihn vorgesehenen Durchgangsloch realisiert wird.The invention has for its object to provide an initiating system of the type mentioned, with simple means a reliable sealing of the firing pin is realized in the intended for him through hole.

Diese Aufgabe wird bei einem Initiiersystem der eingangs genannten Art erfindungsgemäß durch die Merkmale des Kennzeichenteiles des Anspruches 1 gelöst. Bevorzugte Aus- bzw. Weiterbildungen des erfindungsgemäßen Initiiersystems sind in den Unteransprüchen gekennzeichnetThis object is achieved according to the invention in an initiating system of the type mentioned by the features of the characterizing part of claim 1. Preferred embodiments or further developments of the initiator system according to the invention are characterized in the subclaims

Die Erfindung weist den Vorteil auf, dass in jeder Weg-Position des Schlagbolzens eine zuverlässige Abdichtung des Schlagbolzens gegen die Wandung des für ihn im Waffen-Stoßboden vorgesehenen Durchgangsloches gewährleistet ist.The invention has the advantage that in each path position of the firing pin a reliable sealing of the firing pin is ensured against the wall of the provided for him in the weapons shock bottom through hole.

Weitere Einzelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung eines in der Zeichnung abschnittweise und teilweise aufgeschnitten, nicht maßstabgetreu gezeichneten Ausführungsbeispieles des erfindungsgemäßen Initiiersystems in zwei unterschiedlichen Betriebszuständen.Further details, features and advantages will become apparent from the following description of a portion of the drawing and partially cut away, not drawn to scale exemplary embodiment of the initiation system according to the invention in two different operating conditions.

Es zeigen:Show it:

  • Figur 1 das Initiiersystem in der Ausgangsstellung des Schlagbolzens, undFigure 1 shows the initiation system in the initial position of the firing pin, and
  • Figur 2 das Initiiersystem in der End-Zündstellung des Schlagbolzens.Figure 2 shows the initiation system in the final ignition position of the firing pin.

Figur 1 zeigt abschnittweise längsgeschnitten in einem vergrößerten Maßstab, nicht maßstabgetreu, eine Ausbildung des Initiiersystems 10 für eine hülsenlose Munition, von der der Pulverkörper 12 abschnittweise gezeichnet ist. Der Pulverkörper 12 ist in einem Pulver-Querschieber 14 positioniert. An das Patronenlager 14 grenzt ein Waffen-Stoßboden 16 an, der mit einem Durchgangsloch 18 ausgebildet ist. Das Durchgangsloch 18 ist an seiner dem Patronenlager 14 zugewandten Vorderseite mit einer umlaufenden Erweiterung 20 ausgebildet. Im Durchgangsloch 18 des Waffen-Stoßbodens 16 ist eine Dichtungsbuchse 22 angeordnet, die vorderseitig einen umlaufenden Bund 24 aufweist. Der Bund 24 ist in der Erweiterung 20 untergebracht, so dass die Dichtungsbuchse 22 in Bezug zum Waffen-Stoßboden 16 axial nach hinten unbeweglich ist.FIG. 1 shows sections in longitudinal section, to an enlarged scale, not to scale, of an embodiment of the initiating system 10 for a caseless ammunition, of which the powder body 12 is shown in sections. The powder body 12 is positioned in a powder cross slide 14. Adjacent to the cartridge chamber 14 is a weapon thrust plate 16, which is formed with a through hole 18. The through hole 18 is formed on its front side facing the cartridge chamber 14 with a circumferential extension 20. In the through hole 18 of the weapon shock pad 16, a sealing bush 22 is arranged, which has a peripheral collar 24 on the front side. The collar 24 is housed in the extension 20 so that the sealing bushing 22 is immovable axially rearward with respect to the weapon buttock 16.

Die Dichtungsbuchse 22 ist mit einem Schlagbolzen-Durchgangsloch 26 ausgebildet, in dem ein Schlagbolzen 28 axial verstellbar angeordnet ist. Der Schlagbolzen 28 wird beispielsweise mittels eines (nicht gezeichneten) Steuerstückes von der in Figur 1 gezeichneten Ausgangsstellung in die in Figur 2 gezeichnete End-Zündstellung bewegt. Diese Bewegung ist in Figur 1 durch den Pfeil 30 angedeutet.The sealing bush 22 is formed with a firing pin through hole 26 in which a firing pin 28 is arranged axially adjustable. The firing pin 28 is moved, for example by means of a (not shown) control piece from the initial position shown in Figure 1 in the drawn in Figure 2 end ignition position. This movement is indicated in Figure 1 by the arrow 30.

Die im Waffen-Stoßboden 16 für den Schlagbolzen 18 angeordnete Dichtungsbuchse 22 ist mit einem Fettreservoir 32 ausgebildet, das mittels eines Fettkanals 34, der sich durch den Waffen-Stoßboden 16 erstreckt, mit einer (nicht dargestellten) Fettquelle verbunden ist.The sealing bush 22 disposed in the weapon butt 16 for the firing pin 18 is formed with a grease reservoir 32 connected to a grease source (not shown) by means of a grease channel 34 extending through the gun butt 16.

Der Schlagbolzen 28 ist mit mindestens einer umlaufenden Fettrille 36 ausgebildet. Bei der Ausbildung gemäß Figur 1 ist der Schlagbolzen 28 mit zwei axial voneinander beabstandeten umlaufenden Fettrillen 36 ausgebildet.The firing pin 28 is formed with at least one circumferential fat groove 36. In the embodiment according to FIG. 1, the firing pin 28 is formed with two axially spaced circumferential fat grooves 36.

In der in Figur 1 gezeichneten Ausgangsstellung des Schlagbolzen 28 sind die Fettrillen 36 dem Fettreservoir 32 zugeordnet, so dass die Fettrillen 36 mit im Fettreservoir 32 befindlichem Fett 37 gefüllt werden.In the initial position of the firing pin 28 shown in FIG. 1, the fat grooves 36 are assigned to the fat reservoir 32, so that the fat grooves 36 are filled with fat 37 located in the fat reservoir 32.

Wird der Schlagbolzen 28 von der in Figur 1 gezeichneten Ausgangsstellung in die in Figur 2 gezeichnete End-Zündstellung beschleunigt, so nehmen die Fettrillen 36 das in ihnen befindliche Fett 37 mit, wodurch zwischen dem Schlagbolzen 28 und dem Durchgangsloch 26 in der Dichtungsbuchse 42 ein Fettfilm erzeugt wird, der zur Gasabdichtung und zur Vermeidung von Reibspuren beiträgt.If the firing pin 28 is accelerated from the initial position shown in FIG. 1 into the final firing position shown in FIG. 2, the grease grooves 36 entrain the grease 37 in them, thereby forming a greasy film between the firing pin 28 and the through hole 26 in the sealing bushing 42 is generated, which contributes to gas sealing and to avoid traces of friction.

Wie aus den Figuren 1 und 2, in welchen gleiche Einzelheiten jeweils mit denselben Bezugsziffern bezeichnet sind, ersichtlich ist, ist das Durchgangsloch 26 für den Schlagbolzen 28 an seinem dem Patronenlager 14 zugewandten Vorderende mit einem sich zum Patronenlager 14 hin erweiternden Einlaufabschnitt 38 ausgebildet. Der Einlaufabschnitt 38 ist mit einem flachen Konuswinkel kegelstumpfförmig erweitert gestaltet. Desgleichen ist es bspw. möglich, dass der Einlaufabschnitt 38 mit einem sanften Radius erweitert ausgebildet ist.As can be seen from Figures 1 and 2, in which the same details are denoted by the same reference numerals, the through hole 26 is formed for the firing pin 28 at its front end facing the cartridge chamber 14 with an inlet portion 38 widening towards the chamber 14. The inlet section 38 is frustoconically widened with a flat cone angle. Likewise, it is for example possible that the inlet section 38 is formed widened with a gentle radius.

Der Schlagbolzen 28 ist vorderseitig mit einem Abweiser 40 ausgebildet, dessen Funktionsweise weiter unten noch ausführlicher beschrieben wird. Wie aus Figur 2 ersichtlich ist, ist der Abweiser 40 an einem Schlagbolzen-Vorderteil 42 ausgebildet. Das Schlagbolzen-Vorderteil 42 ist rückseitig mit einem Außengewindeabschnitt 44 ausgebildet. Der Schlagbolzen 28 ist vorderseitig mit einer Gewindebohrung 46 ausgebildet. Das Schlagbolzen-Vorderteil 42 ist mit seinem rückseitigen Außengewindeabschnitt 44 in die Gewindebohrung 46 des Schlagbolzens 28 eingeschraubt.The firing pin 28 is formed on the front side with a deflector 40, whose operation will be described in more detail below. As can be seen from FIG. 2, the deflector 40 is formed on a firing pin front part 42. The firing pin front part 42 is formed on the rear side with an externally threaded portion 44. The firing pin 28 is formed on the front side with a threaded bore 46. The firing pin front 42 is screwed with its rear male threaded portion 44 in the threaded bore 46 of the firing pin 28.

Der Schlagbolzen 28 ist vorderseitig außerdem mit einer umlaufenden Dichtungslippe 48 ausgebildet, die innenseitig durch eine sich nach rückwärts kegelstumpfförmig verjüngende Ringfläche 50 bestimmt bzw. begrenzt ist.The firing pin 28 is also formed on the front side with a circumferential sealing lip 48, which is determined or limited on the inside by a frustoconical tapering annular surface 50 backwards.

In Figur 2 ist außerdem ein Zündmittel 52 dargestellt, in das der Schlagbolzen 28 mit seiner Spitze 54 in der Endstellung hineinsteht, um das Zündmittel 52 zu zünden.FIG. 2 also shows an ignition means 52 in which the firing pin 28 with its tip 54 projects into the end position in order to ignite the ignition means 52.

Die Funktionsweise des Initiiersystems 10 gemäß den Figuren 1 und 2 ist wie folgt:The operation of the initiating system 10 according to FIGS. 1 and 2 is as follows:

Der Schlagbolzen 28 wird mittels eines Antriebes, bei dem es sich z.B. um ein nicht dargestelltes Steuerstück handelt, in Richtung des Pfeiles 30 (siehe Figur 1) beschleunigt, so dass die Spitze 54 des Schlagbolzens 28 in den Pulverkörper 12 und in das Zündmittel 52 gestoßen wird. In der in Figur 2 gezeichneten End-Zündstellung wird der Schlagbolzen 28 solange festgehalten, bis sich der vom angezündeten Pulverkörper 12 erzeugte Gasdruck abgebaut hat. Erst danach wird der Schlagbolzen 28 wieder von der in Figur 2 gezeichneten End-Zündstellung in die in Figur 1 dargestellte Ausgangsstellung zurückbewegt. Bei diesen Bewegungen fährt der Schlagbolzen 28 mit seinen Fettrillen 36 in und durch das Fettreservoir 32. Mit dem in den Fettrillen 36 haften bleibendem Fett 37 wird die Wandung des Durchgangsloches 26 gefettet.The firing pin 28 is driven by means of a drive, e.g. is an unillustrated control piece, accelerated in the direction of arrow 30 (see Figure 1), so that the tip 54 of the firing pin 28 is pushed into the powder body 12 and the ignition means 52. In the illustrated in Figure 2 end ignition position of the firing pin 28 is held until the gas pressure generated by the ignited powder body 12 has degraded. Only then is the firing pin 28 moved back again from the end firing position shown in FIG. 2 into the starting position shown in FIG. During these movements, the firing pin 28 moves with its fat grooves 36 into and through the grease reservoir 32. The wall 37 of the through hole 26 is greased with the grease 37 remaining in the grease grooves 36.

In der in Figur 2 gezeichneten End-Zündstellung des Schlagbolzens 28 wird die vorderseitig um den Schlagbolzen 28 umlaufende Dichtungslippe 48 durch den vom angezündeten Pulverkörper 12 generierten Gasdruck aufgeweitet, so dass die Innenwandung des Durchgangsloches 26 nach rückwärts formschlüssig abgedichtet wird.In the illustrated in Figure 2 end ignition position of the firing pin 28, the front around the firing pin 28 circumferential sealing lip 48 is widened by the gas pressure generated by the ignited powder body 12, so that the inner wall of the through hole 26 is sealed form back to the rear.

Der Abweiser 40 des Schlagbolzens 28 verhindert einen direkten Beschuss der umlaufenden Dichtungslippe 48 durch beschleunigte Pulver- und/oder Zündmittelteile.The deflector 40 of the firing pin 28 prevents direct bombardment of the circumferential sealing lip 48 by accelerated powder and / or Zündmittelteile.

Durch den mit einem flachen Konuswinkel kegelstumpfförmig erweiterten Einlaufabschnitt 38 am Vorderende des Durchgangsloches 26 in der Dichtungsbuchse 22 wird ein Verkrusten bzw. Erodieren der dem Schlagbolzen 28 direkt vorgelagerten Übergangskante 56, wie es sich bei einer scharfen d.h. 90°-Kante einstellen würde, verhindert.Due to the frustoconical widened with a shallow cone angle inlet portion 38 at the front end of the through hole 26 in the sealing bush 22 is a crusting or eroding of the firing pin 28 directly upstream transition edge 56, as it is in a sharp. 90 ° edge would be prevented.

Die umlaufende Dichtungslippe 48 kommt in der Anstechbewegung des Schlagbolzens 28 knapp vor der Übergangskante zwischen dem zylindrischen Durchgangsloch 18 und dem Einlaufabschnitt 38 zum Stehen.The circumferential sealing lip 48 comes in the piercing movement of the firing pin 28 just before the transition edge between the cylindrical through hole 18 and the inlet section 38 to a stop.
