Abstract

A bullet (1) for a hand firearm has a bullet core (2) and a core shell (3). The core and the shell are form-fittingly united in the area of the shell base (1a) and the shell (3) is open towards the head (1b) of the bullet. In order to achieve a strong adherence between the core and the shell in the area of their union, independently from the material used, and to preserve the original toughness of the shell (3) in the area of the head, the core shell (3) is constituted of a material whose thickness varies over the axial length of the shell, increasing from the area of the head towards the area of the base.

Description

Geschoß und Verfahren zu seiner Herstellung Projectile and method for its manufacture
Die Erfindung bezieht sich auf ein Geschoß für eine Hand¬ feuerwaffenpatrone aus Geschoßkern und Kernmantel, wobei Kern und Mantel im Bereich des Geschoßbodens formschlüssig miteinander in Verbindung stehen und der Mantel zur Geschoß- spitze hin offen ist, sowie auf ein Verfahren zum Herstellen dieses Geschosses.The invention relates to a projectile for a handgun cartridge made from the projectile core and core casing, the core and casing being positively connected to one another in the area of the floor and the casing being open towards the projectile tip, and to a method for producing this projectile.
Wie aus der AT-B-393 559 hervorgeht, zeichnen sich solche Geschosse sowohl durch eine hohe Durchschlagsleistung und eine mannstoppende Wirkung als auch durch eine relativ kurze Flugbahn beim Verfehlen des Zieles aus, da wegen der Form¬ schlußverbindung zwischen Kern und Mantel der gegenseitige Zusammenhalt von Kern und Mantel stark genug ist, um beim Auftreffen auf weiche oder plastische Zielmedien eine Tren- nung zu vermeiden und ein gemeinsames Eindringen zu gewähr¬ leisten, wobei innerhalb des Zielmediums der Mantel aufge¬ weitet und aufgerollt wird, was zur gewünschten mannstop¬ penden Wirkung führt, dieser Zusammenhalt aber wiederum nicht stark genug ist, um auch dem Auftreffen auf harte Zielmedien standzuhalten, so daß in harte Zielmedien nur der Geschoßkern eindringt und sich der gewünschte Durch¬ schlagseffekt einstellt. Die Öffnung des Kernmantels im Spitzenbereich des Geschosses erleichtert einerseits das Aufrollen des Mantels in weichen Zielmedien bzw. das Ab- streifen des Mantels beim Auftreffen auf harte Zielmedien und bremst anderseits die Fluggeschwindigkeit des Ge- schosses, wodurch auch die Flugbahn bei einem Fehlschuß begrenzt bleibt. Um allerdings die aufgezeigten Wirkungen des bekannten Geschosses sicherzustellen, muß die Form¬ schlußverbindung von Geschoßkern und Kernmantel bestimmten Bedingungen genügen und auch der Kern muß aus einem spezi¬ fisch schwereren Material als der Mantel hergestellt sein.As can be seen from AT-B-393 559, bullets of this type are distinguished both by a high penetration rate and a man-stopping effect and by a relatively short trajectory when the target is missed, since, owing to the positive connection between the core and the shell, mutual cohesion of core and sheath is strong enough to avoid separation when striking soft or plastic target media and to ensure a joint penetration, the sheath being expanded and rolled up within the target medium, which results in the desired man-stop Leads to an effect, but this cohesion is again not strong enough to withstand the impact on hard target media, so that only the projectile core penetrates into hard target media and the desired penetration effect occurs. The opening of the core jacket in the tip area of the projectile facilitates rolling up the jacket in soft target media or stripping the jacket when it hits hard target media and slows down the flight speed of the target. shot, which also keeps the trajectory limited in the event of a miss. However, in order to ensure the effects of the known projectile shown, the positive connection of the projectile core and core casing must meet certain conditions and the core must also be made of a speci¬ fic heavier material than the casing.
Der Erfindung liegt die Aufgabe zugrunde, ein Geschoß der eingangs geschilderten Art zu schaffen, das weitgehend unabhängig von den jeweils verwendeten Materialien ein verbessertes Zusammenwirken von Mantel und Kern mit sich bringt und dadurch auch eine Steigerung der Schußleistung gewährleistet. Außerdem soll ein Verfahren zur rationellen Herstellung eines solchen Geschosses angegeben werden.The invention has for its object to provide a projectile of the type described, which largely independently of the materials used brings about an improved interaction of the jacket and core with it and thereby ensures an increase in the firing performance. In addition, a method for the rational production of such a projectile is to be specified.
Die Erfindung löst diese Aufgabe dadurch, daß der Kernmantel aus einem Material mit über die axiale Mantellänge unter¬ schiedlicher Materialdichte besteht, welche Materialdichte vom Spitzenbereich zum Bodenbereich hin zunimmt. Die höhere Materialdichte im Bodenbereich des Mantels führt zu einer größeren Festigkeit des Materials im Bereich der Formschlu߬ verbindung zwischen Mantel und Kern, wodurch vor allem beim Auftreffen auf weiche Zielmedien ein vorzeitiges Abstreifen des Mantels vom Kern zuverlässig verhindert wird. Im Spit¬ zenbereich des Mantels bleibt das Material wegen der gerin¬ geren Materialdichte weicher und behält seine ursprüngliche Zähigkeit, wodurch ein gleichmäßiges Aufrollen des Mantels entgegen der Schußrichtung beim Auftreffen auf und Ein- dringen in weiche Zielmedien erleichtert wird, so daß sich der Geschoßquerschnitt innerhalb des weichen Zielmediums vergrößert, ohne dabei zu brechen oder zu splittern. Darüber hinaus wird durch die höhere Materialdichte auch eine grö¬ ßere Abriebfestigkeit erreicht, wodurch das Schießverhalten verbessert und einem Schmieren des Geschosses im Lauf vorge¬ beugt wird.The invention solves this problem in that the core jacket consists of a material with a material density that is different over the axial jacket length, which material density increases from the tip area to the bottom area. The higher material density in the bottom area of the jacket leads to greater strength of the material in the area of the form-fitting connection between the jacket and the core, as a result of which premature stripping of the jacket from the core is reliably prevented, especially when it hits soft target media. In the tip area of the jacket, the material remains softer because of the lower material density and retains its original toughness, which makes it easier to roll the jacket evenly against the direction of the shot when it hits and penetrates soft target media, so that the floor cross section is within of the soft target medium without breaking or splintering. In addition, a greater abrasion resistance is achieved due to the higher material density, as a result of which the shooting behavior is improved and lubrication of the projectile in the barrel is prevented.
Zum Herstellen eines aus Geschoßkern und Kernmantel be- stehenden Geschosses wird bisher ein hülsenförmiger Roh¬ mantel mittels geeigneter Werkzeuge auf einen vorgefertigten Kern aufgedrückt und zum fertigen Mantel ausgeformt, wobei das Volumen des Rohmantels im wesentlichen auch dem Volumen des fertigen Mantels entspricht. Wird nun erfindungsgemäß zum Aufbringen des Mantels ein Rohmantel mit im Vergleich zum fertiggeformten Mantel vergrößertem Volumen verwendet, wobei sich der Volumensüberschuß über die axiale Länge in Abhängigkeit von den Unterschieden der Materialdichte im fertiggeformten Mantel ändert, ergeben sich gleichzeitig mit der Ausformung des fertigen Mantels die gewünschten Dichte¬ unterschiede des Mantelmaterials, da eben beim Aufpressen des Rohmantels auf den Kern je nach Größe des Volumens¬ überschusses das Material über die axiale Länge mehr oder weniger verdichtet wird. Zum Aufpressen des Rohmantels auf den Kern, der selbst als Gegenform für die Ausformung des Mantels dient, können alle geeigneten Einrichtungen und Werkzeuge eingesetzt werden, wie Profilrollen zum Aufrollen des Rohmantels auf den Geschoßkern, Profilhämmer zum Auf- hämmern des Rohmantels auf den Geschoßkern oder Preßstempel und Preßmatritzen zum Einpressen von Rohmantel und Kern in die Matritzenform.In order to produce a projectile consisting of a projectile core and core casing, a sleeve-shaped raw casing has so far been pressed onto a prefabricated core by means of suitable tools and shaped into the finished casing, the volume of the raw casing essentially also corresponding to the volume of the finished casing. If, according to the invention, a raw jacket with an increased volume compared to the finished jacket is used for applying the jacket, the excess volume changing over the axial length depending on the differences in material density in the finished jacket, the desired results simultaneously with the shaping of the finished jacket Density differences of the jacket material, because when the raw jacket is pressed onto the core, depending on the size of the excess volume, the material is more or less compressed over the axial length. All suitable devices and tools can be used to press the raw casing onto the core, which itself serves as a counter-shape for shaping the casing, such as profile rollers for rolling the raw casing onto the projectile core, profile hammers for hammering the raw casing onto the projectile core or press ram and press dies for pressing the raw jacket and core into the die form.
Wenn das Mantelmaterial zum Schmieren neigen sollte, ist es möglich, den Rohmantel zumindest im Bodenbereich mit einer äußeren Schutzschicht zu versehen und dann erst auf den Kern aufzubringen, so daß das fertige Geschoß bereits eine entsprechend verschleißfeste Oberfläche besitzt und nicht erst nachträglich oberflächenbehandelt werden muß, was selbstverständlich auch möglich wäre. Um die Schutz- Schicht herzustellen, kann der Rohmantel verkupfert, ver- messingt oder auch kunststoffbeschichtet werden, doch be¬ sonders vorteilhaft ist es, wenn auf den Rohmantel eine zusätzliche Hülse oder einen Napf aus abriebfestem Material aufgesteckt und mit dem Rohmantel verformt wird, wodurch beim Aufpressen und Ausformen des Mantels auch eine exakt ausgeformte Schutzschicht entsteht.If the casing material tends to smear, it is possible to provide the raw casing with an outer protective layer at least in the floor area and only then to apply it to the core so that the finished projectile already has a correspondingly wear-resistant surface and does not have to be surface-treated subsequently which of course would also be possible. To protect To produce a layer, the raw jacket can be copper-plated, brassed or also plastic-coated, but it is particularly advantageous if an additional sleeve or a cup made of abrasion-resistant material is attached to the raw jacket and deformed with the raw jacket, so that during pressing and molding a precisely formed protective layer is created on the jacket.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und zwar zeigen Fig. 1 und 2 zwei Ausfüh¬ rungsbeispiele eines erfindungsgemäßen Geschosses jeweils im Axialschnitt, wobei die linke Hälfte den Kern mit noch unverformtem Rohmantel und die rechte Hälfte den Kern mit fertiggeformtem Mantel veranschaulichen.In the drawing, the subject matter of the invention is illustrated, for example, and FIGS. 1 and 2 show two exemplary embodiments of a projectile according to the invention, each in axial section, the left half illustrating the core with the raw shell still undeformed and the right half illustrating the core with the finished shell.
Ein Geschoß 1 einer nicht weiter dargestellten Handfeuer¬ waffenpatrone umfaßt einen Geschoßkern 2 und einen Kern¬ mantel 3, wobei Geschoßkern 2 und Kernmantel 3 über eine Formschlußverbindung 4 aus umfangseitig verlaufenden, dreh- oder gewindeförmigen Ausformungen 4a miteinander im Bereich des Geschoßbodens la verbunden sind. Der Mantel 3 weist im Bereich der Geschoßspitze lb eine Öffnung 5 auf und besteht aus einem Material, dessen Dichte vom Spitzenbereich zum Bodenbereich hin zunimmt, was durch eine verstärkte Schraf- für angedeutet ist.A projectile 1 of a handgun cartridge, not shown, comprises a projectile core 2 and a core casing 3, the projectile core 2 and core casing 3 being connected to one another in the region of the floor la la by a positive connection 4 made of circumferential, rotating or thread-like formations 4a. The jacket 3 has an opening 5 in the area of the projectile tip 1b and is made of a material whose density increases from the tip area to the base area, which is indicated by an increased hatching.
Zum Herstellen des Geschosses 1 wird auf den vorgefertigten Kern 2 ein hülsenförmiger Rohmantel 3a aufgesteckt, der dann mit Hilfe üblicher Werkzeuge, wie umfangseitig ablaufende Profilwalzen, radial einschlagende Profilhämmer oder axial mit entsprechenden Matritzenformen zusammenwirkende Pre߬ stempel, unter Ausformung zum fertigen Mantel 3 auf den Kern 2 aufgedrückt wird. Der Rohmantel 3a besitzt dabei im Vergleich zum fertiggeformten Mantel 3 ein vergrößertes Volumen und dieser Volumensüberschuß ändert sich über die axiale Länge in Abhängigkeit von den im fertiggeformten Mantel 3 angestrebten Dichteunterschieden des Mantelmate¬ rials. Vor allem im Bodenbereich entlang der Formschluß- Verbindung 4 zwischen Kern 2 und Mantel 3 ist für einen ent¬ sprechenden Volumensüberschuß durch einen Ringansatz 6 ge¬ sorgt, so daß in diesem Bereich der Mantel 3 eine gegenüber dem Spitzenbereich stark erhöhte Materialdichte aufweist. Da diese erhöhte Materialdichte zu einer höheren Festigkeit führt, kommt es zu einem stärkeren Zusammenhalt von Kern 2 und Mantel 3 durch die Formschlußverbindung 4, ohne dabei aber die Zähigkeit des Mantels 3 im Spitzenbereich zu beein¬ trächtigen.To manufacture the projectile 1, a sleeve-shaped raw jacket 3a is placed on the prefabricated core 2, which is then shaped using conventional tools, such as profile rollers running around the circumference, radially driving profile hammers or press dies interacting axially with corresponding die shapes, to form the finished jacket 3 on the Core 2 is pressed open. The raw jacket 3a has an enlarged compared to the finished jacket 3 Volume and this excess volume change over the axial length depending on the desired density differences of the jacket material in the finished jacket 3. Especially in the bottom area along the positive connection 4 between the core 2 and the jacket 3, a corresponding excess volume is provided by a ring extension 6, so that in this area the jacket 3 has a material density that is greatly increased compared to the tip area. Since this increased material density leads to a higher strength, there is a stronger cohesion of the core 2 and the jacket 3 by the form-fitting connection 4, without however affecting the toughness of the jacket 3 in the tip region.
Um das Geschoß 1 mit einer Schutzschicht 7 zu versehen, kann diese Schutzschicht bereits auf den Rohmantel 3a aufgebracht werden, was meist den Beschichtungsvorgang rationalisiert. Wie in Fig. 2 angedeutet, läßt sich dazu auf den Rohmantel 3a auch ein Napf 7a aus geeignetem Material aufstecken, der dann zusammen mit dem Rohmantel 3a zum fertigen, bereits eine Schutzschicht 7 tragenden Mantel 3 verformt wird.In order to provide the projectile 1 with a protective layer 7, this protective layer can already be applied to the raw jacket 3a, which usually rationalizes the coating process. As indicated in FIG. 2, a bowl 7a made of a suitable material can also be attached to the raw jacket 3a, which is then deformed together with the raw jacket 3a to produce the jacket 3 already carrying a protective layer 7.
Das Geschoß 1 mit seiner Formschlußverbindung 4 zwischen Kern 2 und Mantel 3 und der unterschiedlichen Materialdichte des Mantels 3 bringt sowohl eine hohe Durchschlagsleistung als auch eine mannstoppende Wirkung mit sich, da sich der Mantel 3 beim Auftreffen des Geschosses 1 auf ein hartes Zielmedium aufrollt und abgestreift wird und nur der Kern alleine mit entsprechender Durchschlagskraft eindringt, beim Auftreffen auf ein weiches Zielmedium hingegen Kern 2 samt Mantel 3 in das Medium eindringen und sich der Mantel 3 erst innerhalb des Zielmediums unter Vergrößerung des Gescho߬ querschnittes gegen die Schußrichtung aufrollt. Der ver¬ festigte Formschlußbereich einerseits und der weichzähe Spitzenbereich des Mantels anderseits gewährleisten dabei, daß der Zusammenhalt zwischen Mantel und Kern nur durch das Aufprallen auf ein hartes Zielmedium aufbricht und daß im weichen Zielmedium der Mantel gleichmäßig und ohne Bruch- oder Splittergefahr aufgerollt wird. The projectile 1 with its positive connection 4 between the core 2 and the casing 3 and the different material density of the casing 3 brings with it both a high penetration rate and a man-stopping effect, since the casing 3 rolls up and strips off when the projectile 1 strikes a hard target medium is and only the core penetrates with the appropriate penetration force, however, when hitting a soft target medium, core 2 together with the jacket 3 penetrate into the medium and the jacket 3 only rolls up inside the target medium with an increase in the cross section of the projectile against the firing direction. The solidified interlocking area on the one hand and the soft-tough The tip area of the jacket, on the other hand, ensures that the cohesion between the jacket and the core breaks down only by hitting a hard target medium and that the jacket is rolled up evenly in the soft target medium and without the risk of breakage or splintering.
