Definitions

  • the invention relates to a method for producing a cartridge case for cartridge ammunition and also to the cartridge case produced by this method.
  • the propellant charge or cartridge case forms an important part of the cartridge ammunition in addition to the projectile. It is known to produce the propellant charge sleeves in such a way that a cylindrical rod section made of a suitable material is deformed into the propellant charge sleeve in a large number of operations. This involves cold forming and eight forming operations are required to produce a small diameter propellant charge casing, the smaller part of which is extrusion and the larger part of which is drawing. For these operations, expensive machines and tools are required and a large number of ancillary work. In particular, heat treatments must be carried out after or before each cold deformation, after each heat treatment process surface treatment by pickling and then a surface treatment to prepare for the next cold deformation.
  • the invention has for its object to produce propellant charge sleeves from inexpensive material in a less expensive manner.
  • the invention relates to a method for producing a cartridge case for cartridge ammunition, which is characterized in that a base part and a sleeve part are connected to one another by joining.
  • these propellant charge sleeves can also consist of a base part and a sleeve part, which are connected to one another by joining, in particular if the bottom part and the sleeve part are formed and joined in the manner according to the invention.
  • a recess can be arranged on the sleeve part side for receiving the bottom end of the sleeve part. This enables the sleeve part to be centered in a particularly good manner with the base part and if the depression has a hollow cylindrical shape, this not only improves the centering but also the possibilities for connection between the sleeve part and the base part.
  • Turned parts can be used as the bottom part, which, in terms of dimensional accuracy and surface quality, can be manufactured according to requirements without difficulty.
  • Forged parts can also be used as forged parts, the surfaces of which, if at all, only have to be reworked in places.
  • Cone-shaped tubes can be used as sleeve parts, the shaping of which can be carried out, for example, by drawing presses or also by, in particular rolling, pressing onto a mandrel.
  • hollow cylindrical tube sections can also be used, the deformation of which only takes place after connection to the base part. The deformation can, as mentioned above, be carried out by drawing presses, but also at the same time with the connection, in particular by using the same or similar tools as are used when connecting the base part to the pipe part, in particular in roll-press welding.
  • the method according to the invention makes it possible to screw in the thread and, if necessary, the counterbore to receive the ignition screw in the base part before the latter to bind with the sleeve part. This has the advantage that only much smaller parts have to be brought to the processing.
  • the joining can be carried out by friction welding, the base part and the sleeve part being rotated relative to one another about the longitudinal axis of the cartridge. If welding seams occur that exceed the permissible cartridge profile, they can be removed by twisting them off.
  • the joining can also be done by the electron beam welding process. It is possible to arrange the welding points or welding lines between the base part and the sleeve part axially parallel in that the radiation direction is arranged in the longitudinal direction of the cartridge.
  • the collar of the base part can be welded to the outside of the sleeve part by radiation extending in the longitudinal direction of the cartridge or else by radiation extending radially to the longitudinal direction of the cartridge.
  • the joining can also be carried out by press welding. In a particularly simple manner, this is achieved that are disposed within and outside of the workpiece P resspian which rotate as well as the workpiece and that about axes parallel to the longitudinal axis of the workpieces.
  • one or more weld seams or also a circumferential spiral weld seam can be arranged to connect the base part to the sleeve part and these tools or similarly designed tools can be used to deform a tube section into the shape required for the sleeve body.
  • Another possibility for connecting the base part to the sleeve part is laser welding, which is preferably carried out only radially to the longitudinal axis of the cartridge.
  • connection between the base part and the sleeve part can also be made by means of threads arranged radially to the longitudinal axis of the cartridge and by using adhesives between the thread parts.
  • the sleeve part can be shrunk onto the base part, whereby positive-locking and adhesive connections can also be used.
  • the propellant charge sleeve is shown, which, as can be seen from the Fig. consists of the bottom part 1 and the sleeve part 2, wherein both parts are manufactured separately and together reibladungshülse to T have been added.
  • the base part 1 has an essentially tubular extension 3 which extends in the axial direction and which can be inserted into the sleeve part 2.
  • a first possibility of connecting the parts 1 and 2 to one another results from friction welding.
  • parts 1 and 2 must be rotated against one another about the longitudinal axis 5 of the cartridge and pressed against one another.
  • the welding zone is designated 4 in FIG. 2.
  • FIG. 3 A further connection possibility results from FIG. 3.
  • the base part is designated by 1 and the sleeve part by 2.
  • the approach of the bottom part is labeled 3.
  • the connection between the base part 1 and the sleeve part 2 takes place in the area of the attachment 3 by means of a weld seam 6, which was carried out by electron beam welding, the electron beam running parallel to the longitudinal axis 5. Further welds can also take place at 7, also parallel to the longitudinal axis 5, or radially at 8.
  • the base part 1 and the sleeve part can also be connected to one another by pressure welding. This can be seen from FIG. 4.
  • the press-welding tools are designated there with 9 and 1o. These tools can make one or more welds between parts 1 and 2 or they or similar tools can also be used to deform the sleeves part 2.
  • the bottom part 1 and the sleeve part 2 can also be connected to one another by laser welding.
  • the connecting seams required for this are designated by 11 and they extend radially.
  • the connection seams that may be required are identified by 12.
  • connection possibility between the base part 1 and the sleeve part 2 is by threaded connections, which are designated in FIG. 6 with 13 and 14. Adhesives can also be located in these threaded connections.
  • FIG. 7 A further positive connection results from FIG. 7.
  • the sleeve part 2 may have been shrunk onto the base part 1, and adhesives may also be located between the two parts.
  • the method according to the invention has the particular advantage that only a base part and a sleeve part, which can be a simple pipe section, are required to produce a propellant charge sleeve.
  • the bottom part is denoted by 1 and the pipe section by 2.
  • FIG. 9 shows the simple manner in which the sleeve part 2 can be deformed into a cartridge sleeve by contact with a caliber nut 13.
