Description

Die Erfindung beschäftig sich mit einem Geschoss mit einer Abdeckung zur Abdeckung, beispielsweise einer Leuchtspur oder dergleichen, die sich in der Regel im Heckteil eines Geschosskörpers befindet und mit der Thematik, dass die Leuchtspur oder derartige Inhalte luftdicht verschlossen sein muss, da die sonst eindringende Feuchtigkeit etc. dazu führen kann, dass beispielsweise die Leuchtspur - Pyrotechnik- nicht mehr oder nur unzureichend abbrennt. Dazu wird eine Abdeckung, bevorzugt ein Abdeckring, vorgeschlagen, die während des Umformprozesses durch eine axiale Vorschubbewegung eines (starren) Stempels, vorzugsweise aus Metall, radial in eine vorzugsweise vollständig umlaufende Nutkontur des Geschosskörpers gepresst wird. Der Stempel besitzt ein Außenmaß, das von der axialen Position des Stempels gegenüber dem der Abdeckung anhängig ist.The invention deals with a projectile with a cover to the cover, such as a tracer or the like, which is usually located in the rear part of a projectile body and with the theme that the tracer or such content must be hermetically sealed, since the otherwise penetrating moisture etc. may cause, for example, the tracer - Pyrotechnics- no longer or only insufficiently burned. For this purpose, a cover, preferably a cover ring, proposed, which is pressed during the forming process by an axial feed movement of a (rigid) punch, preferably made of metal, radially into a preferably completely circumferential groove contour of the projectile body. The punch has an outer dimension that is pending from the axial position of the punch relative to the cover.

In der Praxis ist vorgesehen, dass der luftdichte Verschluss durch eine Abdeckscheibe etc., in der Regel aus Messing, realisiert wird. Diese wird durch weitere Teile fixiert, wie beispielsweise einem Abdeckring. Dabei wird der Abdeckring beispielsweise durch Umformung des Geschosskörpermaterials gehalten. Weitere Lösungen sind in der Richtung bekannt, dass eine zusätzliche schraube oder Mutter in das Heckteil des Geschosskörpers geschraubt wird.In practice, it is provided that the airtight closure by a cover plate, etc., usually made of brass, is realized. This is fixed by other parts, such as a cover ring. In this case, the cover ring is held for example by deformation of the projectile body material. Other solutions are known in the direction that an additional screw or nut is screwed into the rear part of the projectile body.

Der Nachteil bei der Umformung liegt unter anderem darin, dass oftmals gegensätzliche Anforderungen an das Geschosskörpermaterial gestellt werden. Für die endballistische Wirksamkeit werden harte oder schwer bis nicht verformbare Materialeigenschaften vorausgesetzt, während für den Umformprozess wie Bördeln, Verstemmen etc. weiche oder duktile Materialeigenschaften die Voraussetzung sind. Daher wird der umzuformende Bereich des Geschosskörpermaterials durch Anwendung von Wärmebehandlungsverfahren in den Zustand weich bzw. duktil überführt, was jedoch sehr aufwändig und kosten- wie auch zeitintensiv ist. Die Prozessstabilität ist zudem unter großem Aufwand einzuhalten. Die Bildung von Rissen im Material, die beim Härten oder bei der Umformung entstehen können sind selbst durch die anschließende oder dem Umformungsprozess voran gegangene Wärmebehandlungsverfahren nicht auszuschließen und können als mögliche Fehlerquellen zum Versagen der Abdeckung führen. Schraube und Mutter müssen hingegen nur einer Oberflächenbehandlung unterzogen werden, beispielsweise Hartanodisieren, der Aufwand bei der Montage ist hingegen höher, da Maßnahmen zur Schraubensicherung notwendig sind. Führungsflächen zur besseren Montage nehmen einen entsprechenden Bauraum in Anspruch. Zudem ist das Gewicht einer Schraubverbindung zur Abdeckung der Leuchtspur höher als das eines Abdeckringes.The disadvantage of the deformation is, inter alia, that often conflicting requirements are made of the projectile body material. For end ballistic effectiveness, hard or hard to non-deformable material properties are presumed, while for the forming process such as crimping, caulking etc. soft or ductile material properties are the prerequisite. Therefore, the area of the projectile body material to be reshaped is made soft or ductile by applying heat treatment methods, which is however very complicated and time consuming as well as costly. The process stability is also to be kept at great expense. The formation of cracks in the material, which can occur during hardening or during the forming, are themselves heat treatment processes which have been preceded by the subsequent or the forming process can not be ruled out and can lead to failure of the cover as possible sources of error. On the other hand, the screw and nut only have to be subjected to a surface treatment, for example hard anodizing, but the outlay on assembly is higher since measures for securing the screw are necessary. Guide surfaces for better installation take up a corresponding space. In addition, the weight of a screw to cover the tracer is higher than that of a cover ring.

Hier stellt sich die Erfindung die Aufgabe, ein Geschoss aufzuzeigen, das eine bessere Abdeckung beispielsweise der Leuchtspur ermöglicht.Here, the invention has the object to show a projectile that allows better coverage, for example, the tracer.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgezeigt.The object is achieved by the features of claim 1. Advantageous embodiments are shown in the subclaims.

Der Erfindung liegt die Idee zugrunde, nicht das Geschosskörpermaterial sondern die Abdeckung selbst umzuformen. Dazu wird ein Teil der Abdeckung radial durch einen vorzugsweise starren Stempel, der sich ausschließlich nur axial zu bewegen braucht, und mit einer speziellen Außenkontur versehen ist, in eine umlaufende Nutkontur im Geschosskörper gepresst. Die Außenkontur sollte dabei auf die Nutkontur (oder umgekehrt) abgestimmt sein, damit das von dem in der Vorwärtsbewegung befindlichen Stempel radial umgeformte Material der Abdeckung in die Nutkontur des Geschosskörpers hineingedrückt werden kann und die Abdeckung nach der Umformung über keinerlei Freiheitsgrade mehr verfügt, sodass diese zur Leuchtspur oder dergleichen fixiert ist. Bei der Abdeckung handelt es sich bevorzugt um einen Abdeckring.The invention is based on the idea not to transform the projectile body material but the cover itself. For this purpose, a part of the cover is radially pressed by a preferably rigid punch, which only needs to move axially, and is provided with a special outer contour, pressed into a circumferential groove contour in the projectile body. The outer contour should be matched to the groove contour (or vice versa), so that the radially outwardly formed in the forward movement stamp material of the cover can be pressed into the groove contour of the projectile body and the cover has no degrees of freedom after forming more, so this is fixed to the tracer or the like. The cover is preferably a cover ring.

Da die Abdeckung von innen nach außen verformt wird, wird diese durch die beim Abschuss des Geschosses auftretenden Beschleunigungs-, Massen- und Fliehkräfte gegen den Geschosskörper gedrückt, sodass keine wegfliegenden Teile entstehen. Die Positionierung der Abdeckung mittels eines bevorzugt starren Stempels garantiert eine hohe Prozessstabilität, die eine Vorraussetzung an die Sicherheitsanforderungen ist, um zu verhindern, dass es von wegfliegenden Teilen aufgrund von Fehlern bei dem Umformprozess oder einer unzureichenden Wärmebehandlung kommt.Since the cover is deformed from the inside to the outside, this is pressed by the acceleration, mass and centrifugal forces occurring during the launch of the projectile against the projectile body, so that no flying parts arise. The positioning of the cover by means of a preferably rigid die guarantees high process stability, which is a prerequisite to the safety requirements in order to prevent it from flying off parts due to errors in the forming process or inadequate heat treatment.

Diese Idee kann zudem unabhängig von den Materialeigenschaften des Geschosskörpers angewandt werden und ermöglicht ein Höchstmaß an Flexibilität betreffend der einzusetzenden Materialien für den Geschosskörper.This idea can also be applied independently of the material properties of the projectile body and allows maximum flexibility regarding the materials to be used for the projectile body.

Der nunmehr einfachere Fertigungsprozess ist prozessstabil, Kosten und Zeit optimiert, da es zu einer Reduzierung der Anzahl der einzelnen Arbeitsschritte als auch der fertigungstechnischen Anforderung selbst kommt. Fehlermöglichkeiten, wie beispielsweise eine unzureichende Verformung der Abdeckung oder aber auch ein unrichtiger Sitz, sind auch per Sichtkontrolle leicht erfassbar.The now simpler manufacturing process is process stable, costs and time optimized, since it comes to a reduction in the number of individual steps and the manufacturing requirement itself. Possible errors, such as an insufficient deformation of the cover or even an incorrect seat, are easily detected by visual inspection.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt:

Reference to an embodiment with drawing, the invention will be explained in more detail. It shows:
Fig. 1-3
Method steps for covering a tracer track,
Fig. 4
a sectional view of the cover ring of the figures.

Die Fig. 1 zeigt in einer vereinfachten Darstellung des Grundprinzips des Verfahrens. Mit 1 ist ein Heckteil eines Geschosses 10 bezeichnet, wobei das Heckteil 1 in einer Bohrung 11 eine Leuchtspur 2, 3 aufnimmt. Die Leuchtspur 2, 3 besteht ihrerseits aus einem Leuchtsatz-Pressling 2 und einer Anfeuerung 3, die in der Bohrung 11 bevorzugt eingepresst sind. bei der Leuchtspur 2, 3 handelt es sich in diesem Fall um pyrotechnische Substanzen, die mit anderen chemischen Substanzen, wie sie im Treibladungspulver enthalten sind, reagiert. Eine Abdeckscheibe 4 dient zur Abdichtung der Leuchtspur 2, 3 gegenüber der Umgebung bis zum Zeitpunkt des Verschießens des Geschosses 10 aus einer nicht näher dargestellten Waffe, um einen Kontakt der Substanzen mit feuchter Luft etc. zu vermeiden. Die Abdeckscheibe 4 wird durch einen Abdeckring 6 im Heckteil 1 fixiert.The Fig. 1 shows in a simplified representation of the basic principle of the method. 1 with a rear part of a projectile 10 is designated, wherein the rear part 1 in a bore 11 a tracer 2, 3 receives. The tracer 2, 3 in turn consists of a flare-compact 2 and a 3 cheeks, which are preferably pressed in the bore 11. in the tracer 2, 3 are in this case pyrotechnic substances, which reacts with other chemical substances, such as those contained in the propellant charge powder. A cover 4 is used to seal the tracer 2, 3 from the environment until the time of firing of the projectile 10 from a weapon, not shown, to avoid contact of the substances with humid air, etc. The cover 4 is fixed by a cover 6 in the rear part 1.

Nach dem konventionellen Einpressen der Leuchtspur 2, 3 werden die Abdeckscheibe 4 und der Abdeckring 6 in die dafür vorgesehene Aussparung 12 im Geschosskörper 10 eingelegt, wie in Fig. 2 dargestellt. Anschließend wird der Abdeckring 6 mit einem Stempel 5, vorzugsweise aus Metall, in die Bohrung 11 des Heckteils 1 des Geschosskörpers 10 eingepresst (Fig.2), wobei der Stempel 5 in der Vorwärtsbewegung bzw. der axialen Bewegung und aufgrund seiner (speziellen) Außenkontur 7 den Abdeckring 6 in die vorzugsweise umlaufende Nut 8 im Geschosskörper bzw. Heckteil 1 verformt. Nach dem Verpressen des Abdeckringes 6 inklusive Abdeckscheibe 4 ist die Abdeckung der Leuchtspur 2, 3 in der Bohrung 11 gegenüber der Umgebung sichergestellt, der Umformprozess beendet (Fig.3).After conventional insertion of the tracer 2, 3, the cover 4 and the cover 6 are inserted into the recess 12 provided in the projectile body 10, as in Fig. 2 shown. Subsequently, the cover ring 6 is pressed with a punch 5, preferably made of metal, in the bore 11 of the rear part 1 of the projectile body 10 ( Fig.2 ), wherein the punch 5 in the forward movement or the axial movement and due to its (special) outer contour 7, the cover ring 6 in the preferably circumferential groove 8 in the projectile body or rear part 1 deformed. After pressing the cover ring 6 including cover 4, the cover of the tracer 2, 3 is ensured in the bore 11 relative to the environment, the forming process is completed ( Figure 3 ).

Fig. 4 zeigt in einer Schnittdarstellung eine Abdeckung 6, die bevorzugt als Abdeckring ausgeführt ist. Dieser fixiert die Abdeckscheibe 4. Fig. 4 shows a sectional view of a cover 6, which is preferably designed as a cover ring. This fixes the cover 4.

Alternativ können die Abdeckscheibe 4 und der Abdeckring 6 auch eine einteilige konstruktive Einheit bilden.Alternatively, the cover 4 and the cover 6 can also form a one-piece constructive unit.

Es versteht sind, dass dieses Verfahren nicht auf die Abdichtung einer Leuchtspur im Heckteil 1 eines Geschosses 10 beschränkt ist. So lassen sich mit diesem Verfahren in einfacher Art und Weise auch andere Komponenten, die sich in einer Bohrung oder einem Hohlraum in einem Geschoss, einer Munition etc. befinden, sicher abdichten. Unter Bohrung werden hierbei auch Hohlräume, Ausnehmungen, Öffnungen oder dergleichen im Geschosskörper, Munitionskörper etc. verstanden.It is understood that this method is not limited to the sealing of a luminous trace in the rear part 1 of a projectile 10. Thus, with this method in a simple manner, other components that are in a hole or a cavity in a bullet, ammunition, etc., safely seal. Holes are here also understood as cavities, recesses, openings or the like in the projectile body, ammunition body, etc.
