Description

Die Erfindung betrifft einen Hülsenboden für großkalibrige Munition mit einem Hülsenmantel aus einem verbrennbaren Material.The invention relates to a sleeve base for large-caliber Ammunition with a casing from a combustible Material.

Ein derartiger Hülsenboden ist beispielsweise aus der DE 23 03 790 C3 bekannt. Er besteht aus einer metallischen Bodenplatte und einem randseitig axial über der Bodenplatte hinausragenden und mit einem Auszieherrand versehenen Stützring (Hülsenstummel). Der Stützring dient zur bodenseitigen Abstützung des Hülsenmantels und gewährleistet Gasdichtheit bei Abgabe eines Schusses (Hülsenliderung), da er sich aufgrund der sehr hohen Gasdrücke im Rohr aufweitet und radial an das Waffenrohr anlegt. Außerdem ist bei dem bekannten Hülsenboden geschoßseitig an dem Stützring ein Liderungsring aus Gummi angeordnet.Such a sleeve base is, for example, from DE 23 03 790 C3 known. It consists of a metallic base plate and an edge protruding axially above the base plate and with a pull-out support ring (Hüls stub). The support ring is used for bottom support of the sleeve jacket and ensures gas tightness Firing a shot (sleeve lids) as it is due to the very high gas pressures in the pipe and expands radially to it Gun barrel creates. In addition, the well-known sleeve bottom a rubber eyelet ring on the floor side of the support ring arranged.

Nachteilig ist bei dem bekannten Hülsenboden u.a., daß seine Herstellung mit relativ hohen Herstellkosten verbunden ist, weil aufgrund der hohen Belastungen beim Schuß ein geschmiedeter Stahlrohling verwendet werden muß, der anschließend durch eine spezielle Wärmebearbeitung nachvergütet und schließlich spanend endbearbeitet wird. Außerdem ist der bekannte Hülsenboden nur einmal wiederverwendbar, da er zur Wiederverwendung spanend bearbeitet werden muß und bei mehrmaliger Wiederverwendung die Liderung durch den Stütz- und Dichtring nicht gewährleistet wäre.A disadvantage of the known sleeve base is that its Manufacturing is associated with relatively high manufacturing costs, because a forged steel blank is used due to the high loads on the shot must be re-tempered by special heat processing and finally being machined. In addition, the well-known sleeve bottom reusable only once, as it is machined for reuse must be and the eyelid by the Support and sealing ring would not be guaranteed.

Aus der DE 42 29 559 A1 ist es bekannt, den Hülsenboden großkalibriger Munition zweiteilig, nämlich aus einer metallischen Bodenplatte und einem separaten metallischen Stütz- und Dichtring, aufzubauen. Die Bodenplatte und der Stütz- und Dichtring sind dabei derart formschlüssig miteinander verbunden, daß eine radiale Entkopplung der beiden Teile erfolgt, d.h., bei einer radialen Aufweitung des Stütz- und Dichtringes werden keine wesentlichen Zugkräfte von dem Dichtring auf die Bodenplatte ausgeübt. Dadurch kann die Bodenplatte aus geringerfestem Material hergestellt werden als der Stütz- und Dichtring. Die Anfangsliderung erfolgt wiederum mittels eines zusätzlichen, relativ schmalen Elastomerringes.From DE 42 29 559 A1 it is known the case bottom of large-caliber ammunition in two parts, namely a metallic base plate and a separate metallic one Support and sealing ring to assemble. The base plate and the support and sealing ring are positively connected to each other so that radial decoupling of the two parts takes place, i.e. with a radial expansion of the support and sealing ring no significant tensile forces are exerted by the sealing ring on the base plate. As a result, the base plate can be made of less rigid material than the Support and sealing ring. The initial eyelid again takes place by means of an additional, relatively narrow elastomer ring.

Nachteilig bei diesem Hülsenboden ist unter anderem, daß der Hülsenboden aufgrund der Mehrteiligkeit von Bodenplatte und Hülsenstummel und den erforderlichen Verbindungen dieser Teile miteinander ebenfalls mit relativ hohen Herstellkosten verbunden ist.A disadvantage of this sleeve base is, among other things, that the sleeve base is due to the multiple parts of the base plate and sleeve stub and the required connections these parts also have relatively high manufacturing costs is.

Ferner ist aus der deutschen Patentanmeldung DE-A-197 29 291 ein Hülsenboden bekannt, bei dem auf eine Hülsenliderung verzichtet wird. Diese wird vielmehr von einem entsprechend breit ausgestalteten und mit geringen Herstellkosten verbundenen Elastomerring übernommen, welcher von Schuß zu Schuß ausgetauscht wird und gleichzeitig die Anfangsliderung übernimmt. Furthermore, a sleeve base is known from German patent application DE-A-197 29 291 , in which a sleeve releasing is dispensed with. Rather, this is taken over by a correspondingly broadly designed and low-cost elastomer ring, which is exchanged from shot to shot and at the same time takes over the initial loosening.

Ähnlich wie im Falle der eingangs erwähnten DE 23 03 790 C3 sind bei diesem Hülsenboden die Bodenplatte und der Stützring einteilig ausgebildet, doch ist die Höhe des über die Bodenplatte ragenden Stützringes im Falle der DE-A-197 29 291 so gering, daß lediglich noch eine gewisse Führung und Abstützung des Hülsenmantels im bodenseitigen Bereich, aber keine nennenswerte Aufweitung der Bodenplatte mehr erfolgt. Aus diesem Grund braucht für die Bodenplatte kein geschmiedetes Material mehr verwendet zu werden.Similar to the case of DE 23 03 790 C3 mentioned at the beginning, the base plate and the support ring are formed in one piece in this sleeve bottom, but the height of the support ring projecting over the base plate is so low in the case of DE-A-197 29 291 that only a certain guidance and support of the sleeve shell in the bottom area, but no significant expansion of the base plate takes place. For this reason, forged material no longer needs to be used for the base plate.

Der Elastomerring ist bei dem vorstehend beschriebenen Hülsenboden breitflächig auf die Bodenplatte aufvulkanisiert bzw. aufgeklebt, um beim Entfernen des Hülsenbodens aus dem Waffenrohr die erforderlichen axialen Kräfte übertragen zu können. Eine derartige Herstellung der Verbindung zwischen Bodenplatte bzw. Stützring und Liderungsring ist relativ zeitaufwendig. Außerdem muß der Elastomerring zur Wiederverwendung der Bodenplatte aufwendig mechanisch entfernt werdenThe elastomer ring is broad on the sleeve bottom described above the base plate is vulcanized or glued on to remove the sleeve base to be able to transmit the required axial forces from the weapon barrel. Such one Establishing the connection between the base plate or support ring and eyelid ring is relatively time consuming. In addition, the elastomer ring must be reused the bottom plate can be mechanically removed

Aus der FR-A-1 113 479 ist eine zweiteilige Patronenhülse bekannt, bei welcher der aus Metall bestehende Hülsenmantel mit dem Hülsenboden dadurch verbunden wird, daß das L-förmige Ende des Hülsenmantels in eine nutenförmige Hinterschneidung des Hülsenbodens eingreift und in dieser Stellung durch einen Ring gehalten wird.From FR-A-1 113 479 a two-piece cartridge case is known, in which the sleeve casing made of metal is thereby connected to the sleeve base is that the L-shaped end of the sleeve shell in a groove-shaped undercut of the sleeve base engages and in this position by a ring is held.

Ausgehend von gattungsmäßen Dokument DE-A-197 29 291 liegt der Erfindung die Aufgabe zugrunde, einen Hülsenboden anzugeben, bei dem der Liderungsring auf einfache Weise an dem Stützring befestigt und nach Verschießen der Munition auch wieder entfernt werden kann.Starting from generic document DE-A-197 29 291 , the invention has for its object to provide a sleeve bottom in which the eyelid ring can be easily attached to the support ring and removed after the ammunition has been fired.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. This object is solved by the features of claim 1. More beneficial Embodiments of the invention disclose the subclaims.

Im wesentlichen liegt der Erfindung der Gedanke zugrunde, daß der Stützring auf seiner dem Liderungsring zugewandten Innenseite eine nutenförmige Hinterschneidung aufweist, in die der Liderungsring mit seinem dem Stützring zugewandten Ende form- und/oder kraftschlüssig eingreift.Essentially, the invention is based on the idea that the support ring on its inner side facing the eyelid ring has a groove-shaped undercut, in which the Liderungsring with its end facing the support ring form and / or engages non-positively.

Im einfachsten Fall können Stützring und Liderungsring über eine Schnappverbindung miteinander verbunden sein. Dabei kann der aus einem Elastomer oder Thermoplast bestehende Liderungsring extern hergestellt und dann auf den Stützring aufgedrückt werden. Zur Vereinfachung dieses Fügevorganges können liderungsseitige Schlitze im Schnappbereich vorgesehen sein.In the simplest case, the support ring and eyelid ring can be over a snap connection to be connected. It can the eyelid ring made of an elastomer or thermoplastic manufactured externally and then pressed onto the support ring become. To simplify this joining process slots on the eyelid side are provided in the snap area his.

Bei einer weiteren Ausführungsform der Erfindung hat es sich als vorteilhaft erwiesen, den Liderungsring mit seinem dem Stützring zugewandten Ende auf Letzterem aufzuvulkanisieren oder aufzuspritzen.In a further embodiment of the invention, it has proven to be advantageous, the eyelid ring with its the Vulcanize the end facing the support ring on the latter or spray on.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

  • Fig.1 und 2 die Längsschnitte zweier erfindungsgemäßer Hülsenböden.
    • Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. Show it:
  • 1 and 2 the longitudinal sections of two sleeve bottoms according to the invention.

    • In Fig.1 sind mit 1 ein Hülsenboden für eine großkalibrige Patrone und mit 2 ein Hülsenmantel aus einem verbrennbaren Material bezeichnet. Der Hülsenboden 1 besteht aus einer metallischen Bodenplatte 3 aus Stahl der Wandstärke D und einem geringfügig über die Bodenplatte hinausragenden Stützring 4. Die entsprechende Höhe des Stützringes 4, bezogen auf die innenseitige Oberfläche der Bodenplatte 3, ist mit H1 bezeichnet, wobei für H1 die Beziehung gilt: 0 < H1 < 2D. In Fig.1 are 1 with a sleeve base for a large-caliber Cartridge and with 2 a sleeve casing from a combustible Referred to material. The sleeve base 1 consists of a metallic base plate 3 made of steel with wall thickness D and a support ring protruding slightly beyond the base plate 4. The corresponding height of the support ring 4, based on the inside surface of the bottom plate 3 is with H1 referred to, whereby the relationship applies to H1: 0 <H1 <2D.

    An den Stützring 4 schließt sich geschoßseitig ein Liderungsring 5 aus einem Elastomer, z.B. Gummi, oder Thermoplast an, wobei der Stützring 4 auf seiner dem Liderungsring 5 zugewandten Innenseite 6 eine nutenförmige Hinterschneidung 7 aufweist, in die der Liderungsring 5 mit seinem dem Stützring 4 zugewandten Ende 8 form- und/oder kraftschlüssig eingreift. Hierzu ist der Liderungsring 5 mit seinem dem Stützring 4 zugewandten Ende auf Letzterem aufvulkanisiert oder aufgespritzt.A support ring 4 is closed on the projectile side 5 made of an elastomer, e.g. Rubber, or thermoplastic on, the support ring 4 on its side facing the eyelet ring 5 Inside 6 a groove-shaped undercut 7 has, in which the Liderungsring 5 with its the support ring 4 facing end 8 engages positively and / or non-positively. For this purpose, the eyelet ring 5 with its support ring 4 facing end vulcanized or sprayed onto the latter.

    Sofern sich der Liderungsring 5 nach dem Schuß nicht auf einfache Weise von dem Stützring 4 abziehen lassen sollte, kann der Liderungsring 5 mit einem einfachen Messerschnitt, z.B. im Bereich der sich im Liderungsring 5 ergebenden Hinterschneidung 9, getrennt und die beiden sich ergebenden Einzelteile dann von dem Stützring 4 entfernt werden. Die entsprechende Trennlinie ist in Fig.1 gestrichelt dargestellt und mit dem Bezugszeichen 10 bezeichnet.Unless the eyelet ring 5 is not easy after the shot Should be deducted from the support ring 4 can the eyelet ring 5 with a simple knife cut, e.g. in the area of the undercut in the eyelet ring 5 9, separated and the two resulting individual parts then be removed from the support ring 4. The corresponding The dividing line is shown in dashed lines in FIG designated by the reference numeral 10.

    In Fig.2 ist ein Fig.1 im wesentlich entsprechender mit 1' bezeichneter Hülsenboden dargestellt, bei dem allerdings der Liderungsring 5' nicht auf den Stützring 4' aufvulkanisiert oder aufgespritzt wurde, sondern zunächst als separates Teil hergestellt und dann mit dem Stützring 4' über eine Schnappverbindung 11 verbunden wurde. Zur Vereinfachung des Fügens im Schnappbereich ist der Liderungsring 5' mit Schlitzen 12 versehen. Vorzugsweise sollten für eine gute Anfangsliderung die Fertigungstoleranzen für den Stützring 4' und den Liderungsring 5' so ausgeformt sein, daß sich 2 Preßsitze 13, 14 ergeben. In Fig.2 a Fig.1 is essentially corresponding with 1 ' designated sleeve bottom shown, in which, however, the Liderungsring 5 'not vulcanized onto the support ring 4' or sprayed on, but first as a separate part manufactured and then with the support ring 4 'via a snap connection 11 was connected. To simplify joining in the snap area is the eyelet ring 5 'with slots 12 Mistake.
