Definitions

  • the invention is based on the problem, so far as to form a bullet cartridge of the type mentioned that it allows high pull-out resistances with small scattering. Furthermore, a method for producing the Geunterpatrone is to be created, which allows high pull-out resistances with small scattering. - -
  • the first layer may alternatively or in addition to graphite also molybdenum disulfide, boron nitride or Teflon use as an additive.
  • a blurring of the layers can be according to another advantageous embodiment of the invention easily avoided when the two layers are applied to the inside of the sleeve, wherein a closer to the edge of the sleeve disposed first layer, the additive and a deeper disposed in the sleeve second layer no or contains a lower level of additive than the first layer.
  • the first layer provided with the additive is pressed against the other second layer.
  • the provided with the additive first layer is smoothed and thus produces a particularly homogeneous layer.
  • FIGS. 1-3 schematically show several method steps for producing a projectile cartridge.
  • FIG. 1 shows a projectile 1 and a sleeve 2 prior to joining to a bullet cartridge 3 shown in FIG. 3.
  • the sleeve 2 is shown in a longitudinal section.
  • two layers 4, 5 are applied on the inside of the sleeve 2.
  • a first layer 4 arranged closer to the free edge of the sleeve 2 contains bitumen mixed with an additive.
  • a second, more deeply arranged in the sleeve 2 layer 5 contains bitumen without additive.
  • the layers 4, 5 can be created with a suitable tool, preferably by means of a spraying technique in a single operation.
  • the Geschosparatronen invention 3 have an initial pull resistance of over 600 N.
  • FIG. 5 shows a force-expansion diagram of pull-out resistances of a plurality of projectile cartridges, which, according to the prior art, have only a non-positive connection of the projectile 1 with the sleeve 2.
  • the comparison of FIGS. 4 and 5 shows that the course of the purely frictional connection according to FIG. 5 runs significantly more irregularly over the elongation. Furthermore, the initial pull-out resistance in the purely frictional connection is only half of the pull-out resistance of the bullet cartridge 3 according to the invention.

Abstract

L'invention concerne une cartouche de projectile et un procédé de production d'une cartouche de projectile. Pour étanchéifier (6) un projectile (1) vis-à-vis d'une douille (2) d'une cartouche (3) de projectile, deux couches (4, 5) sont appliquées l'une sur l'autre. L'une des couches (4) contient un milieu d'étanchéité très visqueux, en particulier un mélange bitumineux, comprenant un additif servant à augmenter les propriétés de glissement, tandis que l'autre couche (5) contient le milieu d'étanchéité exempt d'additif. Lorsque le projectile (1) est assemblé à la douille (2), la couche (5) exempte d'additif empêche l'enfoncement de la couche (4) pourvue de l'additif dans la douille.
