Definitions

  • the invention relates to a one-piece steel sleeve for cartridges made from a blank by extrusion, comprising a sleeve base, a sleeve body which consists of one piece with the sleeve base and forms a sleeve wall, a shoulder cone which forms a uniformly thick wall and with the sleeve body consists of one piece.
  • the invention further relates to a device for producing a cartridge case - consisting of a case base, a case body, a shoulder cone and a case neck, the wall thickness of the case body continuously decreasing from the case base against the shoulder cone and the wall of the shoulder cone being thicker than the wall of the case body at its thinnest point - in the extrusion process with an extrusion mandrel.
  • the wall thickness of the shoulder cone is equal to or less than the wall thickness of the sleeve body.
  • the object which is to be achieved with the present invention is to create a cartridge case which, when the cartridge is fed to the weapon, is able to withstand the forces which arise without undesirable compression of the shoulder cone.
  • the cartridge case according to the invention is characterized in that the wall thickness of the case wall of the case body steadily decreases from a first value S1 on the case bottom to a value S2 at a middle point, and then steadily increases again from this second value S2 at this middle point to a third value S3 on the shoulder cone, this middle point being closer to the shoulder cone than to the base of the sleeve, that the shoulder wall of the shoulder cone has a greater wall thickness than the sleeve body at the middle point mentioned and that a sleeve neck in front of the Shoulder cone with this consists of one piece, the wall thickness of which is smaller than the wall thickness of the shoulder cone.
  • the wall of the sleeve body 13 becomes steadily thinner from the sleeve bottom 11 against the shoulder cone 14 up to the point S2 and then steadily thicker up to the point S3.
  • the wall of the shoulder cone 14 either becomes steadily thinner from the sleeve body 13 against the sleeve neck 15 or has the same thickness everywhere.
  • the wall of the shoulder cone 14 is thicker than the wall of the sleeve body 13 at point S2. 1, the wall thickness of the sleeve body 13 steadily decreases from the value S1 to the value S2 and then increases again steadily to the value S3.
  • the wall of the shoulder cone 14 has the same wall thickness everywhere with the value S3.
  • the sleeve neck 15 has the same wall thickness everywhere with the value S4.
  • the reinforcement of the wall of the shoulder cone 14 is necessary since this area of the cartridge case 10 is subjected to greater stress when the cartridge is fed to the weapon, in particular due to the acceleration or deceleration forces.
  • an extrusion mandrel 16 is used to produce the cartridge case 10 according to the invention, which has a recess or circumferential groove 17 on its periphery in the region of the shoulder cone 14, such that a thickening 18 forms in the sleeve wall when the cartridge case 10 is extruded.
  • a thickening 18 forms in the sleeve wall when the cartridge case 10 is extruded.
  • This thickening 18 is pressed radially outwards, as indicated in FIG. 2 with a broken line.
  • This cut-out 17 on the extrusion mandrel 16 makes it more difficult to strip the cartridge case 10 from the extrusion mandrel 16 without requiring a special stripping device. In this way, the necessary wall thickening 18 is achieved in the desired area and in the desired extent.
  • the wall is thickened by the desired amount at the desired location and the shoulder cone 14 is thus reinforced.
  • the immersion conditions of the sleeve when it is fed into the cartridge chamber are influenced and adapted to the requirements.
