Definitions

  • the invention relates to a fragmentation plate in front of an explosive charge with the features of the preamble of claim 1.
  • Such fragmentation plates with spheres or with spheres that have lateral flattenings in the cross section of a hexagon are arranged on the circumference of an explosive charge of an explosive grenade or another projectile.
  • the splinter plate can be arranged flat or - with respect to the explosive - curved outwards or inwards.
  • Such splinter plates can also be arranged in daughter storeys of ejection floors which are fired and ejected one after the other.
  • the known prior art is e.g. B. in US-PS 3,667,390 and DE-PS 28 21 723 and 29 07 308 described.
  • a disadvantage of the known arrangements is a complicated manufacturing process, since the individual spherical bodies have to be soldered to one another and the plates have to be cast on the surface with hard solder. As a result, mounting plates are required which hold the individual metal bodies in their position during the manufacturing process of the splinter plate.
  • the invention is therefore based on the object to improve a splinter plate with the features of the preamble of claim 1 in such a way that on the one hand its manufacture is possible without essential assembly aids, and on the other hand that the spherical bodies are always ejected at the same time in the desired direction after being behind the Splinter plate has formed a corresponding ejection pressure can take place.
  • the effectiveness of the sliver plate should be increased.
  • the shell used according to the invention on the explosive side of the metal body can serve on the one hand as a mounting plate. On the other hand, it ensures that the balls are not ejected until a uniform pressure has built up behind this shell. As a result, a higher fragmentation speed of the metal bodies can be achieved than was previously possible.
