Definitions

  • the invention relates to a method for producing a fragment jacket for a projectile, in which there is an explosive charge inside the fragment jacket, which is ignited by an igniter and in which the fragment jacket is produced by deep drawing from a disc, into which predetermined breaking points in the form of grooves be embossed before the disc is formed into a splinter jacket.
  • a warhead (DE-GM 84 27 780.7) there is a warhead housing for receiving a hollow landing, as well as a detonator connected to the warhead housing.
  • This warhead housing is cup-shaped and is made from a metal round blank by a forming process, such as deep drawing. A wire mesh is rolled into this blank. This known manufacturing process is complex. The wire mesh has no particular advantages.
  • the object which is to be achieved with the present invention is to create a simplified production process which is particularly suitable for the mass production of such splinter shells.
  • this object is achieved in that the disk has different thicknesses, corresponding to the shape of the splinter jacket to be produced, before the disk is formed into a splinter jacket.
  • the projectile 10 has a cup-shaped fragment jacket 11.
  • This fragment jacket 11 has a bottom 12 which is arranged at the rear end of a sleeve-shaped body 13.
  • the rear part 14 of the sleeve-shaped body 13 has a smaller inner diameter than the front part 15, ie the wall of the rear part 14 is thicker than the wall of the front part 15 and the bottom 12 is thicker than that Wall of the rear part.
  • This fragment jacket 11 is made from a disc 11 ', which is shown in Fig.2 and 3 and which is indicated in Fig.1 in dash-dotted lines.
  • this disc 11 ' has an inner part 12', the thickness of which corresponds to the thickness of the base 12, a central annular part 14 ', the thickness of which corresponds to the thickness of the rear part 14 of the sleeve-shaped body 13 and an outer annular part 15 ', the thickness of which corresponds to the thickness of the front part 15 of the sleeve-shaped body 13.
  • the inner part 12 ' is thicker than the middle part 14' and this is thicker than the outer part 15 '.
  • One side of the disc 11 is provided with grooves 16.
  • the shape of these grooves can be seen better in FIGS. 6 and 7.
  • these grooves 16 have a triangular cross section and according to Figure 7 there are longitudinal grooves 16 'and transverse grooves 16 ⁇ .
  • the side of the disk 11 'provided with grooves 16' comes after the shaping of the disk 11 'into the splinter jacket 11 on the inside of the splitter jacket 11.
  • the shaping of the disk 11' in the splitter jacket 11 is carried out in a conventional manner, in particular by deep drawing.
  • the projectile 10 contains an explosive charge 17 inside the fragment jacket 11. This explosive charge 17 is ignited by a head detonator 18. This igniter 18 is screwed into an internal thread 19 of the splinter jacket 11.
  • An amplifier charge 20 at the rear end of the detonator 18 projects into the interior of the explosive charge 17.
  • the projectile 21 likewise has a cup-shaped fragment jacket 22.
  • This fragment jacket 22 has a tip 23, which is a sleeve-shaped Body 24 closes at the front.
  • This fragment jacket 22 is thicker at the front at the tip 23 than at the rear end and this fragment jacket 22 is made from a disc 22 ', which in the middle part 23' - which forms the tip 23 - is also correspondingly thicker.
  • This disc 22 ' has according to Figure 5 on its lower side longitudinal and transverse grooves 16' and 16 ⁇ , as already described above, see Fig.6 and Fig.7.
  • a base igniter 25 is screwed into the fragment jacket 22, which has an amplifier charge 26 which projects into the inside of an explosive charge 27 which is located in the fragment jacket 22.
  • the sleeve-shaped part 24 has the same thickness at the front and rear.
  • the disc 22 is only divided into a middle thicker part 23 'and a thinner outer part 24'.
  • a ballistic hood 28 is required. According to FIG. 4, this ballistic hood 28 is only placed on the smooth surface of the splinter jacket 22. If a more precise fastening is required, an additional groove can be present in the splinter jacket, as described below with reference to FIG. 8.
  • the projectile 29 has a cup-shaped splinter jacket 30.
  • This splinter jacket 30 differs from the projectile 21 shown in FIG. 4 and described above by the following features.
  • a peripheral groove 32 is arranged in the splinter jacket 30 for fastening a ballistic hood 31.
  • the splinter jacket 30 not only has a much thicker tip 33, but also a thicker sleeve-shaped section 34. In between there is a middle, thinner section 36 also the disc 30 'formed differently.
  • This disc 30 ' is divided into an inner, thicker part 33', a middle, thinner part 36 'and an outer, thicker annular part 34'.
  • a disc 37 ' is shown with the predetermined breaking points formed by grooves 38', 38 ⁇ .
  • the pattern of these grooves is chosen so that regular hexagons or quadrilaterals are formed when the disk 37 'is formed into a splinter jacket.
  • the radial grooves 38 ⁇ are preferably impressed less deeply into the disk 37 'than the annular grooves 38'. This has the advantage that a uniform disintegration of the splinter jacket into fragments of the desired size is achieved by the different embossing depth of the grooves 38 'and 38 ⁇ .
