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 projecting axially above the base plate and with a pull-out support ring (Sleeve stub). The support ring is used for ground 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 eyelid 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 bottom is that its Manufacturing is associated with relatively high manufacturing costs, because due to the high loads on the shot a forged one Steel blank must be used, which subsequently tempered by a special heat treatment and is finally machined. In addition, the known sleeve bottom reusable only once because it is used Reuse must be machined and repeated Reuse 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 einei 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 to calibrate the base of the sleeve Ammunition in two parts, namely from a metallic Base plate and a separate metallic support and Sealing ring to build up. The bottom plate and the support and Sealing rings are positively connected to one another, that the two parts are radially decoupled, i.e. with a radial expansion of the support and sealing ring no significant tensile forces from the sealing ring exercised the bottom plate. This can make the bottom plate out less strong material than the support and Sealing ring. The initial eyelid again takes place using a 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 bottom is, among other things, that the Sleeve base due to the multiple parts of the base plate and Sleeve stub and the connections required Parts with each other also with relatively high manufacturing costs connected is.

Schließlich ist aus der unveröffentlichten deutschen Patentanmeldung 19729291.7 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.Finally, from the unpublished German patent application 19729291.7 a case bottom known in which a sleeve cover is dispensed with. Rather, it will of a correspondingly broad and low Manufacturing costs associated elastomer ring taken over, which is exchanged from shot to shot and at the same time the Initial delivery takes over.

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 Patentanmeldung 19729291.7 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 are the base plate and the support ring for this sleeve base formed in one piece, but is the height of the floor plate protruding support ring in the case of patent application 19729291.7 so low that only a certain leadership and support of the sleeve jacket in the bottom area, but no significant expansion of the base plate takes place. For this reason, no need for the base plate forged material to be used more.

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 werden.The elastomer ring is in the sleeve bottom described above vulcanized onto the base plate over a wide area or glued to when removing the sleeve bottom from the Gun barrel transmit the necessary axial forces too can. Such a connection between Base plate or support ring and eyelid ring is relative time consuming. In addition, the elastomer ring must be reused the bottom plate mechanically removed become.

Ausgehend von der Patentanmeldung 19729291.7 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.The invention is based on patent application 19729291.7 the task of specifying a sleeve bottom at which the eyelid ring on the support ring in a simple manner attached and removed after the ammunition was fired can be.

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. Disclose further advantageous refinements of the invention 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 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.On the support ring 4, a eyelid ring closes on the floor 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 on 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 was 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.
