Description
Patronenhülse aus Kunststoff Es ist bekannt, Patronenhülsen aus Kunststoff im Spritzverfahren einteilig herzustellen. Um den starken Beanspruchungen, denen die Kunststoffpatronenhülse ausgesetzt ist, entgegenzutreten, hat man vorgeschlagen, die Patronenhülse aus Kunststoff zu verstärken, indem man eine Innenhülse aus Leichtmetall oder auch aus Kunststoff hinzufügt (Doppelhülse). Dieses kompliziert aber das Herstellungsverfahren und somit die wirtschaftliche Herstellung derartiger Patronenhülsen. Beim Schießen hat sich gezeigt, daß sich die Patronenhülsen durch die Zugbeanspruchung um ein gewisses Maß längen. Derartige Längendehnungen werden aber auch durch die obengenannten Konstruktionen solcher Patronenhülsen nicht aufgefangen.Cartridge cases made of plastic It is known, cartridge cases made of plastic to be produced in one piece by injection molding. To the heavy use that the plastic cartridge case is exposed to counteract it has been proposed Reinforce the cartridge case made of plastic by making an inner case made of light metal or also made of plastic (double sleeve). However, this complicates the manufacturing process and thus the economical production of such cartridge cases. When shooting has been shown that the cartridge cases by the tensile stress to a to a certain extent. Such length expansions are also due to the above Constructions of such cartridge cases not caught.
Es wird nun eine Patronenhülse aus Kunststoff vorgeschlagen, deren unteres Drittel, d. h. der Teil, der sich an das Bodenstück anschließt, aus einem elastischeren Kunststoff besteht als der Rest der Patronenhülse. Hierdurch wird eine Zone mit hoher Dehnung geschaffen, die ein Abreißen der Hülse beim Schuß verhindert.It is now proposed a cartridge case made of plastic, whose lower third, d. H. the part that adjoins the bottom piece from one made of more elastic plastic than the rest of the cartridge case. This will created a zone of high elongation that prevents the case from tearing off when fired.
Die Figur zeigt beispielsweise eine derartige Patronenhülse aus Kunststoff.The figure shows, for example, such a cartridge case made of plastic.
Der an das Bodenstück 1 sich anschließende Teil t der Patronenhülse besteht aus dem elastischeren Kunststoff, während der Rest 3 der Patronenhülse aus dem weniger elastischen Kunststoff besteht. Hierbei werden vorzugsweise Kunststoffe verwendet, die, obwohl gleicher Provenienz, unterschiedliche elastische Eigenschaften haben, wobei Weichmacherzusätze tunlichst vermieden werden, da durch ihre Wanderung die Pulverladung beeinträchtigt werden kann. Solche Kunststoffe sind z. B. Hochdruckpolyäthylen und Niederdruckpolyäthylen. Das Hochdruckpolyäthylen wird hierbei zur Bildung der elastischen Zone verwendet, während das Niederdruckpolyäthylen den restlichen Teil der Patronenhülse ausmacht. Weiterhin kann ein Kunststoff auf der Basis von Polyvinylchlorid verwendet werden, wobei einerseits als elastisches Polyvinylchlorid eine Mischung von Polyvinylchlorid und chlorierten Polyäthylenen und andererseits ein Polyvinylchlorid ohne Weichmacher benutzt wird.The part t of the cartridge case adjoining the base piece 1 consists of the more elastic plastic, while the rest of 3 is made of the cartridge case the less elastic plastic. Plastics are preferred here which, although of the same provenance, have different elastic properties where plasticizer additives are avoided as far as possible, because of their migration the powder loading can be affected. Such plastics are z. B. high pressure polyethylene and low pressure polyethylene. The high pressure polyethylene is used to form the elastic zone used, while the low pressure polyethylene the remaining part the cartridge case. Furthermore, a plastic based on polyvinyl chloride can be used be used, on the one hand a mixture as elastic polyvinyl chloride of polyvinyl chloride and chlorinated polyethylenes and, on the other hand, a polyvinyl chloride is used without plasticizers.
Die Herstellung derartiger Patronenhülsen kann so erfolgen, daß man die Spritzform gleichzeitig und von zwei Seiten aus mit den in ihrer Elastiziät unterschiedlichen Kunststoffen füllt. Die beiden Kunststoffmassen vereinigen sich dann beim Spritzvorgang zu einem Stück.The manufacture of such cartridge cases can be done in such a way that one the injection mold at the same time and from two sides with the elasticity different plastics. The two plastic masses unite then into one piece during the injection process.
