Abstract

Lead projectiles produce gases containing lead powder when they are shot, which poses a health risk. For this reason, special ventilation regulations have to be respected in indoor shooting facilities. The lead residue left during outdoor shooting is also harmful to the environment and has to be collected and disposed of. The necessary precautions relating to lead projectiles in terms of the protection of human beings and the environment are complicated and expensive. According to the invention, the projectile (1) consists of a lead-free material with a density greater than 5 g/cm3.

Description

Bleifreies Kleinkaliber-Vollgeschoss Lead-free, small-caliber bullet
Die Erfindung betrifft ein Kleinkaliber-Vollgeschoss.The invention relates to a small-caliber full floor.
Kleinkaliber-Vollgeschosse werden in der Regel aus Blei und Bleilegierungen hergestellt, beispielsweise, indem von einem Bleidraht abgeschnittene Stücke in Matrizen zu Geschossen verformt werden. Kleinkaliber-Schießen ist eine Sportart, die sowohl im Freien als auch in Hallen durchgeführt wird. Das Verschießen von Bleigeschossen erzeugt bleistaubhaltige Gase, die gesundheitsschädlich sind. Deshalb müssen beim Schießen in Hallen besondere Vorschriften bezüglich der Belüftung beachtet werden. Weiterhin müssen beim Schießen im Freien die für die Umwelt schädlichen Bleirückstände der Geschosse eingesammelt und entsorgt werden. Die beim Verschießen von Bleigeschossen erforderlichen Maßnahmen zum Schutz von Mensch und Umwelt sind aufwendig und teuer.Small-caliber bullets are usually made of lead and lead alloys, for example by shaping pieces cut from a lead wire into bullets in dies. Small-caliber shooting is a sport that is performed both outdoors and indoors. The firing of lead bullets produces gases containing lead dust that are harmful to health. For this reason, special regulations regarding ventilation must be observed when shooting in halls. Furthermore, when shooting outdoors, the lead residues of the projectiles, which are harmful to the environment, must be collected and disposed of. The measures required to protect people and the environment when firing lead bullets are complex and expensive.
Es ist deshalb die Aufgabe der Erfindung, die aufgezeigten Nachteile beim Verschießen von Kleinkaliber-Vollgeschossen zu vermeiden.It is therefore the object of the invention to avoid the disadvantages shown when firing small-caliber bullets.
Die Lösung der Aufgabe erfolgt mit Hilfe der kennzeichnenden Merkmale des ersten Anspruchs. Vorteilhafte Ausgestaltungen der Erfindung werden in den Unteransprüchen beansprucht.The problem is solved with the aid of the characterizing features of the first claim. Advantageous embodiments of the invention are claimed in the subclaims.
Statt des toxisch wirkenden Bleis und seiner Legierungen wird erfindungsgemäß ein Kleinkaliber-Geschoss aus einem bleifreien Werkstoff vorgeschlagen, dessen Dichte > 5 g/cm3 ist. Ein solcher Werkstoff weist aufgrund seiner Dichte eine ausreichende Flugbahnstabilität auf. Beim Verschießen entstehen keine toxischen Bleistäube und beim Verschießen im Freien brauchen die Geschossreste nicht eingesammelt zu werden, da sie die Umwelt nicht kontaminieren. Als besonders geeignete Werkstoffe, die sowohl hinsichtlich ihrer Härte, ihrer Dichte als auch ihrer Unbedenklichkeit gegenüber der Umwelt in Frage kommen gehören die Metalle Zinn oder Zink oder Legierungen dieser beiden Werkstoffe. Zinn hat eine Dichte von etwa 7,2 g/cm3 und Zink von etwa 7,3 g/cm3.Instead of the toxic lead and its alloys, a small-caliber bullet made of a lead-free material is proposed according to the invention, the density of which is> 5 g / cm 3 . Such a material has sufficient trajectory stability due to its density. When firing, there are no toxic pencils, and when firing outdoors, the remains of the bullets do not need to be collected as they do not contaminate the environment. The metals tin or zinc or alloys of these two materials belong as particularly suitable materials, which are suitable both in terms of their hardness, their density and their harmlessness to the environment. Tin has a density of about 7.2 g / cm 3 and zinc of about 7.3 g / cm 3 .
Weiterhin kann der Werkstoff auch ein Kunststoff sein, vorzugsweise ein Thermoplast, der sich leicht durch Spritzgießen zu einem Geschoss formen läßt. Besonders vorteilhaft sind Kunststoffe, die in der Natur verrotten. Diese Geschosse werden auf natürlichem Wege beseitigt, so daß kein aufwendiges Einsammeln erforderlich ist.Furthermore, the material can also be a plastic, preferably a thermoplastic, which can easily be molded into a projectile by injection molding. Plastics that rot in nature are particularly advantageous. These bullets are removed naturally, so that no time-consuming collection is required.
Einfluß auf die Flugbahneigenschaften von Geschossen aus Kunststoff kann dadurch genommen werden, daß dem Kunststoff Metallpulver mit hoher Dichte, beispielsweise Wolfram, beigemischt wird. Je höher der Anteil des Metallpulvers, desto schwerer wird das Geschoss, was sich bei entsprechend angepasster Treibladung positiv auf die Flugbahnstabilität und die Durchschlagskraft auswirkt.Influence on the trajectory properties of projectiles made of plastic can be influenced by adding high-density metal powder, for example tungsten, to the plastic. The higher the proportion of metal powder, the heavier the projectile becomes, which has a positive effect on trajectory stability and penetration when the propellant charge is adjusted accordingly.
Blei ist gegenüber den genannten Werkstoffen des erfindungsgemäßen Geschosses in der Regel weicher. Deshalb erfolgt durch die Verformung des Geschosshecks eine gute Liderung im Lauf. Weichblei hat eine Vickers-Härte von etwa 5 HV. Die Vickers- Härte von Zinn liegt ebenfalls bei etwa 5 HV, während die Härte von reinem Zink 35 HV beträgt. Um bei Werkstoffen, die härter sind als Blei, eine gleich gute Liderung zu erreichen, muß die vom Geschossheck ausgehende Vertiefung in Form, Tiefe und Durchmesser auf den jeweils verwendeten Werkstoff abgestimmt werden. Diese Vertiefung hat in der Regel die Form einer Kalotte. Erst eine optimale Liderung ergibt einen präzisen Schuß. Die vom Heck ausgehende Vertiefung eines Geschosses aus bleifreiem Werkstoff ist deshalb in der Regel wesentlich stärker ausgeprägt als bei einem Bleigeschoss. Dadurch werden die verbleibenden Wände der Hülsenaufnahme, insbesondere im Bereich des Hecks, dünn und deshalb auch bei härteren Werkstoffen als Blei leicht verformbar. Die Vertiefung kann bei harten Werkstoffen bis zu 65 % der Länge der Hülsenaufnahme ausmachen. Diese ist in der Regel etwa 3 mm lang.Lead is generally softer than the materials mentioned for the projectile according to the invention. For this reason, the deformation of the rear end of the bullet lifts the barrel well. Soft lead has a Vickers hardness of around 5 HV. The Vickers hardness of tin is also around 5 HV, while the hardness of pure zinc is 35 HV. In order to achieve equally good eyelids for materials that are harder than lead, the shape, depth and diameter of the recess from the rear of the projectile must be matched to the material used. This depression is usually in the form of a spherical cap. Only an optimal eyelid results in a precise shot. The deepening of a projectile made of lead-free material starting from the rear is therefore generally much more pronounced than that of a lead projectile. As a result, the remaining walls of the sleeve receptacle, in particular in the area of the tail, become thin and therefore easily deformable even with harder materials than lead. The depression can be hard Make up materials up to 65% of the length of the sleeve holder. This is usually about 3 mm long.
Um bei den gegenüber Blei härteren Geschosswerkstoffen einen vergleichbaren festen und gleichmäßigen Sitz des Geschosses in der Patronenhülse reproduzierbar zu gewährleisten, weist die Hülsenaufnahme des Geschosses eine Hülseneinzugsnut auf. Nur so kann eine Hülsenkneifung mit festem Geschosssitz und eine hohe Standzeit der Kneifwerkzeuge erreicht werden. Die Hülsenkneifung bewirkt eine gleichmäßige Geschossausziehkraft. Dieses wirkt sich positiv auf die Präzision des Schusses und damit auf die Treffgenauigkeit aus.In order to ensure reproducibly a comparable firm and even fit of the projectile in the cartridge case in the case of bullet materials which are harder than lead, the case receptacle of the projectile has a case insertion groove. This is the only way to achieve sleeve pinching with a fixed projectile seat and a long service life for the pinching tools. The sleeve pinching causes an even projectile pulling force. This has a positive effect on the precision of the shot and thus on the accuracy.
An Hand eines Ausführungsbeispiels wir die Erfindung näher erläutert.The invention is explained in more detail using an exemplary embodiment.
Die Figur zeigt ein erfindungsgemäßes Kleinkaliber-Vollgeschoss 1 , hier aus einer Zinklegierung, in vergrößertem Maßstab. Gegenüber den herkömmlichen Geschossen weist die Hülsenaufnahme 2 folgende Unterschiede auf: Um eine bei dem harten Werkstoff Zink optimale Liderung zu erreichen, dringt die Vertiefung in Form einer Kalotte 3 vom Heck 4 tief in die Hülsenaufnahme 2 ein. Dadurch werden die verbleibenden Wände der Hülsenaufnahme 2, insbesondere im Bereich des Hecks 4, dünn und deshalb auch bei Zink als einem härteren Werkstoff als Blei leicht verformbar. Vom Heck 4 des Geschosses 1 bis zum Pol 5 der Kalotte 3, der auf der Achse 6 des Geschosses liegt, erstreckt sich die Kalotte 3 über eine Tiefe 7 in die Hülsenaufnahme 2 des Geschosses. Die Tiefe 7 beträgt beim vorliegenden Ausführungsbeispiel 65 % der Gesamtlänge 8 der Hülsenaufnahme 2.The figure shows a small-caliber full storey 1 according to the invention, here made of a zinc alloy, on an enlarged scale. Compared to the conventional projectiles, the sleeve receptacle 2 has the following differences: In order to achieve optimal lids with the hard material zinc, the depression in the form of a spherical cap 3 penetrates deeply into the sleeve receptacle 2 from the rear 4. As a result, the remaining walls of the sleeve receptacle 2, in particular in the area of the tail 4, become thin and therefore easily deformable even with zinc as a harder material than lead. From the rear 4 of the projectile 1 to the pole 5 of the calotte 3, which lies on the axis 6 of the projectile, the calotte 3 extends over a depth 7 into the sleeve receptacle 2 of the projectile. In the present exemplary embodiment, the depth 7 is 65% of the total length 8 of the sleeve receptacle 2.
Damit das Geschoss 1 einen festen Sitz in der Hülse 9 hat, weist die Hülsenaufnahme 2 eine Hülseneinzugsnut 10 auf. In diese Hülseneinzugsnut 10 ist der Hülsenrand 11 eingedrückt, was eine Hülsenkneifung mit festem Geschosssitz bewirkt. So that the projectile 1 has a tight fit in the sleeve 9, the sleeve receptacle 2 has a sleeve insertion groove 10. The sleeve edge 11 is pressed into this sleeve insertion groove 10, which causes a sleeve pinching with a fixed projectile seat.
