Definitions

  • the invention relates to a projectile according to the preamble of claim 1 and a method for its production.
  • FR-1 242 187 describes a projectile with a projectile body, a casing made of a projectile tip and a projectile casing fastened to the outside of the projectile tip, and a sealing body which closes the casing at the rear and encompasses the projectile body in its rear region.
  • the diameter of the projectile body is approximately zeppelin-shaped, which means that it increases from front to back and then decreases again. It is therefore not possible to first manufacture the jacket and then to equip it with the projectile core, which would be desirable in order to produce the same casings in large series and then to produce different projectiles from them by equipping them with different projectile bodies. In particular, it is not possible to produce the tip of the projectile by injection.
  • a bullet is known from FR-812 377 , in which it would be possible, depending on the intended use, to equip the same jackets with different bullet cores.
  • This projectile has a projectile body centered at the front by a ring and a casing surrounding the latter, which is closed at the rear by a metallic sealing body which surrounds the projectile body in its rear region; above all, the sealing body should also form an additional mass, that is to say be relatively heavy, and must therefore be made of metal.
  • the jacket encompasses the projectile tip and the projectile envelope formed integrally with the projectile tip and is also made of metal.
  • the main disadvantage of this projectile is that it is relatively complex to produce, in particular since the casing and sealing body are both made of metal, so that it is not possible to produce one or both of the parts by injection molding.
  • a projectile is known from FR-2 238 137 , the projectile core of which is conical in its front half and cylindrical in its rear half. This core is surrounded by a jacket.
  • the shape would basically allow the same shells to be fitted with different projectile bodies from the rear and thus to produce different projectiles.
  • the shell of this projectile is formed by a projectile tip made of sprayable material, more precisely plastic, which is molded onto a metallic projectile shell.
  • the rear opening of the casing is closed by a closure or sealing body which projects into the casing and partially surrounds the projectile core.
  • the outer surface of the jacket is formed in the front part of the projectile by the projectile tip and in the rear part of the projectile by the metallic sealing body; in this respect, the projectile is of the same design as that of US Pat. No. 3,795,196, but, in contrast to the projectile of US Pat . No. 3,795,196 mentioned , has a projectile casing .
  • the projectile casing which rests on the projectile body in the central region, does not lie on the outer surface of the casing, but merely serves to form an indirect screw connection between the projectile tip and the sealing body.
  • a collar which is formed on the part of the sealing body which projects into the jacket serves as the centering arrangement for the projectile body.
  • the invention is therefore based on the object, based on a prior art according to FR-2 238 137 , to propose a projectile of the type mentioned at the outset and a method for its production, in which the casing with projectile bodies of different types, in accordance with the respective intended use, can be equipped, and which can be produced in a simple and therefore inexpensive manner.
  • the floor body On the new floor, the floor body is designed so that its diameter is from front to back constant or increasing, but in any case not decreasing, so that the projectile core can be inserted into the prefabricated casing from behind.
  • the Sheath consists of a generally metallic shell and a bullet tip made of a sprayable, hardened material, preferably plastic, which is injected onto the shell.
  • the centering arrangement is therefore on the new floor provided on an injection molded component, just at the top of the projectile that the high cost of manufacturing the centering assembly on a metallic component be avoided.
  • the outer surface of the jacket that in the front part of the storey is formed by the bullet tip, in the rear part of the bullet from the metallic Projectile shell formed, which they as a solid mounting base for attaching the guide ring can be used.
  • the opening of the jacket is closed by means of a sealing body that extends into the interior extends of the jacket and thereby partially surrounds the projectile core.
  • the guide ring does not have to be attached to the sealing body, it is preferred not only the bullet tip but also the sealing body made of plastic and generally molded after fitting the jacket, so that manufacturing and Assembly can be carried out in one operation.
  • a molded sealing body you get a particularly inexpensive projectile, because this means the projectile body is completely fixed in the axial direction without, for example, a high-precision mechanical production is to be carried out or also in cases where the storey core is manufactured with a relatively large tolerance.
  • the first step in the manufacture of the projectile is the projectile tip the projectile shell is injected and in a second step the projectile body from behind pushed into the centering arrangement up to a stop.
  • the seal body attached is preferably done by introducing sprayable Material is made inside the shell or shell, after which the projectile body on the front of the stop, on the side of its peripheral surface and on the back of its End surface completely from the spray material of the bullet tip and the sealing body is surrounded.
  • the projectile tip 3 which consists of an injection-molded material, preferably a high-temperature-resistant, fiber-reinforced thermoplastic, is injected onto the projectile casing 2 in a first step of a manufacturing process, wherein it is arranged in front projectile casing grooves 4 , which are arranged inside the projectile casing 2 are, penetrates and is anchored in this way.
  • the projectile tip 3 has a cylindrical recess 5, which is coaxial with the longitudinal axis of the projectile, for receiving and centering a projectile body 6 .
  • the bottom surface 8 of which is curved in a partially circular manner concentrically with the bore 5 .
  • four webs 9 are arranged on the edge of the recess 5 , which are offset by 90 ° against the grooves 7 and which are at a distance from one another which is the same size as the width of the grooves 7 .
  • the webs 9 are arcuate in cross section and have a thickness which corresponds to the depth of the grooves 7 .
  • the recess 5 continues in the direction of the projectile tip in a cylindrical recess extension 10 which also runs coaxially to the longitudinal axis of the projectile and has a smaller diameter than the recess 5 and together with the recess 5 a shoulder which is intended to provide an axial stop 11 for to form the floor core.
  • the projectile body 6 which is also sometimes referred to as a projectile core or penetrator, has, according to the first exemplary embodiment of FIGS. 1 to 4, a cylindrical shape with rounded projectile body edges 12 , 13 at the ends.
  • the projectile body 6 has practically the same diameter as the recess 5 and is provided on its exterior with circumferential projectile body grooves 14 .
  • the projectile body 6 is pushed through the projectile casing 2 , which is still open on the rear side, which is shown in FIG. 3 , along the webs 9 into the recess 5 up to the stop 11 on the shoulder provided for this purpose and in this position kept centered.
  • the sprayable material also penetrates into the grooves 7 and between the webs 9 of the projectile tip 3 and into the projectile body grooves 14 on the projectile body 6 .
  • the projectile body 6 is then completely surrounded by the sprayable or sprayed material at the front on the shoulder forming the stop 11 , laterally and at the rear, and is firmly anchored in the jacket 1 .
  • the sprayable material also penetrates into further middle projectile casing grooves 16 provided on the inside of the projectile casing 2 and into rear projectile casing grooves 17, as a result of which the sealing body 15 is firmly anchored in the projectile casing 2 , as is shown in FIGS. 1 and 2 can be seen.
  • a sleeve circumferential groove 18 for fastening a cartridge case, not shown, and an annular circumferential groove 19 are provided, a guide ring 20 for guiding the projectile in a weapon barrel in the circumferential ring groove is appropriate.
  • the projectile body of the second embodiment consists of several partial projectile bodies 21 to 25 .
  • the partial storey bodies 21 to 25 can consist of cylinder-like pills lined up in the longitudinal direction of the storey, which, as described above with reference to FIG. 1, are inserted in the second manufacturing step into the centering formed by the recess 5 and the webs 9 and in the formation of the
  • the sealing body 15 is surrounded by the sprayable material and firmly anchored.
  • Partial storey structures of different shapes and numbers can also be used.
  • the type or the material of the partial storey body can also be different in general or within one storey. For example, frangible heavy metal can be used for the sub-storey elements 21 and 24, ductile heavy metal for the sub-storey elements 22 and 25 and a fire set for the sub-storey element 23 .
  • a guide ring 31 is embedded in a circumferential groove 32 of a projectile casing 30 .
  • the guide ring 31 is formed integrally with the sealing body 33 by injecting the high-temperature, fiber-reinforced thermoplastic material into the projectile casing 30, which is still open at the rear.
  • a plurality of radially extending openings 34 are provided in the circumferential groove 32 for the exit of the sprayable material from the projectile shell 30 .
