Definitions

  • the invention relates to a rimfire cartridge according to the preamble of claim 1 and a method for producing a rimfire cartridge according to the preamble of Claim 3.
  • a rimfire cartridge according to the prior art is shown in FIG. 1.
  • a cartridge case 2 has on its base 3 a radial bulge 10 into which an ignition charge 1 is introduced.
  • the cartridge case 2 is filled with propellant powder 11 and sealed is the propellant charge container 2 with a floor 12.
  • Known primers 1 contain heavy metals and are very sensitive to impact and friction, d. H. that the known rimfire cartridges even with a low firing pin energy uniform and complete implementation of the primer with a shorter ignition time Ensure t ⁇ 1 ms.
  • the invention has for its object a rimfire cartridge according to the preamble of claim 1 and a method for producing a rimfire cartridge according to to improve the preamble of claim 3 such that even with low pollutants Ignition kits at low firing pin energy a complete and even Implementation of the firing rate is guaranteed with short ignition times, so that ignition failures are eliminated.
  • this object is achieved with respect to the rimfire cartridge by that the bottom of the cartridge case is pressed in at least in some areas and thereby reduces the opening of the bulge to the inside of the cartridge case is.
  • the bottom is in the circumference of the inner diameter the cartridge case pressed inward in the axial direction.
  • the firing pin energy is thereby only for the deformation of the bulge or how to says, used to deform the slot in which the primer is located and does not have to lose ground deformation in the center of the bottom of the cartridge case Experienced. This significantly improves the sensitivity to ignition.
  • the bulge after the introduction of the Ignition charge pressed and thereby compressed the ignition charge.
  • This is the Implementation of the primer improved.
  • the primer can also on this compression or repressing the bulge to be dispensed with.
  • the bulge is compressed or re-pressed with a tool with flat pressure surfaces, e.g. B. a pair of pliers.
  • a tool with flat pressure surfaces e.g. B. a pair of pliers.
  • the bulge has a more rectangular cross section.
  • An alternative advantageous embodiment is characterized in that the bulge is pressed with a sharp-edged tool, only the one to the Cartridge case adjacent area of the bulge is pressed. hereby the bulge has a more teardrop-shaped cross section.
  • the task is related to the method of manufacturing a rimfire cartridge solved in that the bottom of the Cartridge case is pressed in at least in some areas and thereby the opening of the bulge to the inside of the cartridge case is reduced.
  • the bottom of the cartridge case is advantageously in the circumference of the inner diameter the cartridge case pressed inwards in the axial direction.
  • the bulge for compression after the introduction of the Ignition charge pressed. In one embodiment, this is done with a tool with flat printing areas and in another embodiment with a sharp-edged tool, only the area adjacent to the cartridge case the bulge is pressed in.
  • Fig. 2a shows a cartridge case 2 of a rimfire cartridge according to the invention in Cut.
  • a circumferential bulge 10 is arranged on the bottom 3 of the cartridge case 2, in which an ignition charge is usually introduced in liquid form during filling is (see Fig. 1).
  • the bottom 3 of the cartridge case is in the entire area up to pressed axially inward onto the actual bulge 10, so that a dome-shaped Soil 3 was created.
  • FIG. 2b shows the area of the bulge 10 on an enlarged scale. It's good too recognize that by pressing the bottom 3, the opening 13 of the bulge 10 is reduced to the inside of the cartridge case 2, this is a dam of the ignition charge introduced.
  • Fig. 2b shows the bulge 10 after the Repress with a tool with flat pressure surfaces. Before repressing the bulge 10 or the sleeve edge 7 had that shown in dashed lines in the figure Contour 8. This re-compression compresses the ignition charge, not shown.
  • the reference number 9 shows the radial width of the bulge 10. With the reference symbol 5 the desired excess of the height of the bulge 10 is shown before the re-pressing.
  • the reference number 4 indicates the height of the bulge 10 after the re-pressing on.
  • Reference number 6 is the tolerated inner edge height of the bulge 10 indicated after the re-pressing.
  • 3a shows an alternative embodiment of the cartridge case 2 or the bulge 10.
  • the bottom 3 is pressed axially inward, so that the opening 13 the bulge 10 to the inside of the cartridge case 2 is reduced (see Fig. 3b).
  • 3b shows the bulge 10 again on an enlarged scale.
  • the bulge 10 or the sleeve edge 7 is here of the desired oversize 5 (see dashed outline 8) pressed to the required final height 4, so that a tolerated inner Edge height 6 has arisen.
  • the repressing was done in this embodiment, however with a sharp-edged tool that only adjoins the cartridge wall Has depressed the region of the bulge 10 or the sleeve edge 7.
