Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung eines schadstoffarmen Mantelgeschosses nach dem Oberbegriff des Patentanspruchs sowie auf ein nach diesem Verfahren hergestelltes Geschoss.The present invention relates to a method for the production of a low-emission shell bullet the preamble of the patent claim as well as to an after this Processed bullet.
Seit Jahrhunderten wird kostengünstiges Blei aufgrund seiner hohen Dichte und Weiche als Geschossmaterial oder zumindest als Kernmaterial für Geschosse verwendet. Der langjährige Einsatz von bleihaltigen Geschossen in Übungs- und Jagdmunition hat zu grossen toxischen Problemen geführt und insbesondere die Umgebung von Schiessanlagen stark mit Schwermetall belastet. Somit war es nur eine Frage der Zeit, bis die Forderung nach schadstoffarmen, insbesondere bleifreien Geschossen aufkam. So wurde beispielsweise in manchen Ländern vom Gesetzgeber bereits ein Schrotverbot erlassen für die Jagd über Wasser- und Sumpfgebieten.For centuries, inexpensive lead has been used because of its high density and soft as bullet material or at least used as core material for projectiles. The longtime Use of lead-containing projectiles in practice and Hunting ammunition has led to major toxic problems and especially the surroundings of shooting ranges Heavy metal contaminated. So it was just a matter of Time until the demand for low pollution, in particular lead-free bullets came up. For example, in In some countries, the law already bans grist enacted for hunting across water and marshlands.
Aus der EP -A- 0641836 ist es bekannt, zur Erzeugung von Massen hoher Dichte, Wolframpulver in eine Kunststoffmatrix einzulagern, welche in Geschossen und als Angelgewichte Verwendung finden. Dabei werden diese in einem aufwendigen Herstellungsverfahren bei Temperaturen von über 185 °C vor allem zu schadstoffarmer Jagdmunition verarbeitet.From EP -A- 0641836 it is known for the production of Masses of high density, tungsten powder in a plastic matrix store, which in storeys and as fishing weights Find use. In doing so, these are elaborate Manufacturing process at temperatures above 185 ° C all processed into low-emission hunting ammunition.
Dieses Verfahren weist den Nachteil einer kostenintensiven thermischen Prozessführung auf und ist daher für eine Ordonnanzmunition zu teuer. Im weiteren lässt sich die Dichte des Geschosses nur in engen Grenzen einstellen; zudem ist die Dimensionsstabilität bei Temperaturschwankungen, aufgrund des hohen Kunststoffanteils im Kern, ungenügend.This method has the disadvantage of being costly thermal process control and is therefore for ordnance ammunition too expensive. Furthermore, the density can be of the projectile only within narrow limits; is also dimensional stability due to temperature fluctuations the high proportion of plastic in the core, insufficient.
Es ist daher Aufgabe der Erfindung ein Verfahren zu schaffen, welches die Nachteile des Stands der Technik nicht aufweist, mit überall vorhandenen Betriebseinrichtungen umsetzbar ist, insbesondere keine thermischen Prozesse mit entsprechenden Anlagen erfordert und sich in der resultierenden Dichte auf einfache Weise einstellen lässt.It is therefore an object of the invention to provide a method which does not have the disadvantages of the prior art can be implemented with existing operating facilities is, in particular, no thermal processes appropriate facilities required and reflected in the resulting Density can be set easily.
Das nach diesem Verfahren geschaffene Geschoss soll, verglichen mit einem existierenden und bisher in grossen Serien hergestellten Geschoss (Ordonnanz-Munition 5.6 mm GP90) ein gleiches Gewicht, eine gleiche Aussengeometrie, eine identische Innen- und Aussenballistik und eine gleiche Durchschlagsleistung aufweisen. Im weiteren soll die Dimension des Geschosses auch in einem weiten Temperaturbereich erhalten bleiben und - selbstverständlich - müssen sämtliche Auflagen der Haager-Konvention durch das Substitutionsprodukt ebenfalls erfüllt sein.The projectile created according to this procedure should be compared with an existing and so far in large series manufactured bullet (Ordonnance ammunition 5.6 mm GP90) same weight, same outer geometry, an identical indoor and outdoor ballistics and the same Have breakthrough performance. Furthermore, the dimension should of the projectile also in a wide temperature range must be preserved and - of course - must all requirements of the Hague Convention through the substitute product also be fulfilled.
Zusätzlich soll das Geschoss flüssigkeitsdicht ausgestaltbar sein; Fabrikationstoleranzen sollen durch die Konstruktion des Geschosses kompensierbar werden.In addition, the projectile should be liquid-tight his; Manufacturing tolerances should be due to the design of the floor can be compensated.
