Definitions

the invention relates to a splinter body for splinter projectiles, in which splinters designed as spheres are pressed between two centrally arranged shells, the outer shell being plastically molded into a recess having the balls.
the object of the invention is therefore to design the end-face contact surfaces of the sleeves so that the outer sleeve is connected to the inner sleeve in a gas-tight manner.
the invention solves this problem in that the recess is dovetail-shaped and the outer shell with its corresponding end faces rests over the entire surface with relatively high pressure.
a further advantage of the invention is that the front end connection of the inner and outer shell is stable in the case of highly stressed projectiles.
An inner shell 1 has a dovetail-shaped recess 2 with undercut end faces 3 and 4.
the inner shell 1 forms, with an outer shell 5, a projectile body 6.
Balls 10 designed as fragments are forged between the inner shell 1 and the outer shell 5.
a sealing ring can be forged in the area 11 on the peripheral surfaces to improve the sealing effect.
