Definitions

  • the invention relates to a method for fastening a ballistic hood to a projectile body, which has a smooth surface for receiving the hood, the ballistic hood being provided with adhesive on its inner surface lying against the projectile body.
  • annular groove is produced on the projectile body for fastening the hood to the projectile body, and an annular rib is formed on the ballistic hood, which engages in the groove of the projectile body.
  • the projectile body 10 has a conical hood support 11 at its front end. Behind this hood support 11 there is a cylindrical hood centering 12 and a conical section 13 to which a cylindrical section 14 is connected. In the rear part of the projectile body 10, two circumferential grooves 15 are provided, which serve to anchor the projectile body 10 in a sabot, not shown. A light set sleeve 17 is anchored in the conical, rear end face 16. A ballistic hood 18, described with reference to FIG. 2, is attached to this projectile body by a method described below.
  • the projectile body 10 is located in a chuck 19 and the ballistic hood 18 protrudes into a press-fit chuck 20.
  • a pressing die 21 is used to press the ballistic hood 18 onto the projectile body 10.
  • the projectile body 10 located in the chuck 19 is finally supported on one Support sleeve 22 from.
  • the ogive-shaped ballistic hood 18 has a cavity which is formed by three sections, namely a front, conical section 23, a rear, conical section 24 and a central, cylindrical section 25.
  • the rear conical section 24 opens out into a cylindrical part 26.
  • a conical support surface 27 is provided, which is supported on the conical hood support 11.
  • the inner surface 28 of the rear, conical section 24 has a number of relatively easily deformable ribs 29.
  • a recess 30 for receiving adhesive 31 is provided in front of these ribs 29 (FIG. 1).
  • the projectile body 10 is first inserted into the chuck 19 until it is supported on the support sleeve 22. Furthermore, the ballistic hood 18, after it has been provided with adhesive in the recess 30, is inserted into the press-fit chuck 20 and pressed onto the projectile body 10. Finally, with the aid of the pressure stamp 21, the inner surface 28 is pressed against the smooth surface 32 of the conical section 13 on the projectile body 10.
  • the ribs 29 are deformed and thus enable the ballistic hood 18 to be precisely centered, thereby preventing the hood 18 from sitting obliquely on the projectile body 10.
  • the described method for fastening the ballistic hood 18 to the projectile body 10 it is no longer necessary to arrange fastening grooves on the projectile body 10 for fastening the hood 18 to the projectile body 10. Thanks to the conical support surface 27 of the hood 18, which is supported on the conical hood support 11 and thanks to the ribs 29, which are supported on the smooth surface 32 of the conical section 13 on the projectile body 10, the hood 18 is reliably centered on the projectile body 10 guaranteed. In addition, the cylindrical part 26 of the hood 18 is pushed onto the cylindrical hood centering 12 with a press fit. Furthermore, the adhesive 31 ensures reliable fastening supply of the hood 18 on the projectile body 10.
