Definitions

  • the invention relates to a device for fastening a cartridge case to a projectile, in particular a sub-caliber projectile, wherein at least one circumferential groove is provided on a sabot and the cartridge case can be connected to the sabot of the projectile by notching on the circumferential groove.
  • a sabot for a wing-stabilized lower-caliber projectile which has become known, for example, with the European patent application 0 624 774 , is composed of a sabot body and a sabot jacket.
  • a circumferential groove is provided on the sabot body, wherein the cartridge case can be connected at this point by notching to the sabot carrying the projectile.
  • Such a connection must be tight, so that the required high explosion pressure can build up during ignition and the powder in the cartridge case is protected against the ingress of liquids.
  • the invention is therefore based on the object of proposing a device of the type mentioned by means of which a tight connection between cartridge cases made of sheet steel and projectiles can be produced while avoiding the disadvantages mentioned above.
  • a pressure piece for receiving the projectile, which has a cylindrical extension which projects into a bore in a die.
  • an elastic ring is arranged, one end face of which faces the cylindrical extension of the pressure piece, and the other end face of which, via a sealing washer, bears against two slides guided perpendicular to the longitudinal axis of the cartridge in the die .
  • the die is pushed against the pressure piece with the slides, the elastic ring being pressed together via the sealing disk and being deformed inward in the radial direction, so that the sleeve mouth is pressed into the circumferential groove.
  • the elastic ring is made of Vulkolan type Adipren.
  • the sealing washer is made, for example, of hardened spring steel 0.3 mm thick, the edge of the inner diameter of the sealing washer facing the elastic ring being rounded.
  • the advantages achieved by the invention can be seen in the fact that uniform, tight connections between cartridge cases made of sheet steel and projectiles can be produced with a long service life of the elastic ring.
  • This is achieved in particular through the use of the proposed sealing washer and its design.
  • the sealing washer protects the elastic ring from the movement of the slide, the wear of the elastic ring during the small movement towards the slide being very small due to the small thickness of the sealing washer and the rounded edge. As tests confirm, can therefore of the high forces occurring, at least 5000 patronizing cycles can be achieved without any noticeable abrasion of the elastic ring being detectable.
  • 1 denotes a receptacle in which a pressure piece 2 is arranged, which is held in the receptacle 1 by a locking ring 3 .
  • the pressure piece 2 has a cylindrical projection 4 which projects into a bore 5 of a die 6 which is also arranged in the receiving bushing 1.
  • the pressure piece 2 receives the bullet of a cartridge 7 during the cartridge described in more detail below, the bullet tip 8 being guided in a centering 9 and a conical part of the cartridge case 10 being received in the die 6 .
  • an elastic ring 14 is arranged, which consists, for example, of Vulkolan of the Adipren type.
  • the outer diameter of the elastic ring 14 corresponds to the diameter of the bore 5 , while its inner diameter is larger than the diameter of the sleeve mouth 11 or the projectile.
  • One end face of the elastic ring 14 faces the end face of the cylindrical extension 4 , while the other end face rests against two slides 16 via a sealing washer 15 .
  • the slides 16 are guided perpendicular to the longitudinal axis 17 of the cartridge 7 in the die 6 and can be moved by means of double-acting cylinders 18 fastened to brackets 18.1 , for example pneumatically operated.
  • the Sealing disc 15 is preferably made of hardened spring steel 0.3 mm thick. The outer diameter of the sealing disk 15 corresponds to the diameter of the bore 5 , while its inner diameter is a little more than the diameter of the sleeve mouth 11 or the projectile.
  • a compression spring 20 is arranged in the receiving bushing 1 , which rests on the one hand on a shoulder 21 of the pressure piece 2 and on the other hand on a shoulder 22 of the die 6 .
  • the cartridge 7 is held at its rear end on a base 23 movable in the longitudinal axis 17 of the cartridge 7 by a resilient insert 24 and a holder 25 .
  • the base 23 with the cartridge 7 is raised and the projectile is pushed through the die 6 into the pressure piece 2 .
  • the slides 16 are then pushed inwards by the two cylinders 18 until they abut the cartridge case 10 .
  • the gap given by the play between the sealing disk 15 and the cartridge case 10 is bridged by the slides 16 ( FIGS. 2 and 3 ).
  • the receiving bushing 1 and with it the die 6 with the slides 16 are raised by means of a notch cylinder, which is also, for example, hydraulically actuated, not further shown, against the fixed pressure piece 2 and the compression spring 20 and the elastic ring 14 is pressed together via the sealing disk 15 .
  • the elastic ring 14 is deformed radially inwards and the sleeve mouth 11 is pressed into the circumferential groove 13 of the sabot 12 ( FIG. 3 ).
  • the sealing disk 15 protects the elastic ring 14 from the movement of the slider 16 , the wear of the elastic ring 14 during the small movement towards the slider 16 being very low because of the rounded edge 19 of the sealing disk 15 .
  • the notch cylinder and then the two cylinders 18 are moved back again, so that the receiving bushing 1 , the die 6 and the two slides 16 assume the starting position again.
  • the push-in cylinder then moves back so that the notched cartridge 7 can be removed from the base 23 and a new one can be put on.
