Definitions

  • the invention relates to a projectile for firing range and practice cartridges with a cylindrical rear part and a bow-side Ogiven Scheme, wherein the
  • Ogiven Council has a rear-side end and a projectile nose.
  • Bullets, especially for police use, are characterized by the fact that they are either dimensionally stable (military) or deforming (police deployment). Shells that deform will increase in impact
  • Softtargets are the cross-sectional area and thus the surface load is reduced to values that can be absorbed by a protective vest usually a high penetration performance due to the material, since the material deformability is low. Lead is much more ductile in this context.
  • the invention has for its object to construct a projectile that behaves in the soft target as a classic full-coat round-headed projectile (projectile with a closed shape consisting of a cylindrical guide member and an ogive, largely dimensionally stable).
  • the projectile should have a low energy output in the soft target, no deformation and no splintering.
  • protective materials of bullet catches it should come to no punching effect.
  • Typical police use projectiles punch 4 mm holes in rubber-like materials. This punching effect increases the costs in training operation.
  • This object is achieved in that the bullet is integrally formed, the Ogiven Scheme is closed on all sides and has a cavity and the wall thickness of the Ogiven Schemes steadily decreases from the rear end to the top. Upon impact of the bullet of the invention on a target of the Ogiven Scheme is compressed due to the cavity (see Figure 3).
  • the bullet in the soft target behaves like a classic full-jacketed round-headed bullet.
  • the projectile has a low energy output in the soft target, does not deform substantially and has no splintering. The fact that the projectile is closed on all sides, it comes in protective materials of bullet traps to no punching effect.
  • the projectile has no predetermined breaking points. Predetermined breaking points would favor splinter formation.
  • the starting material of the projectile is advantageously a copper-wrought alloy,
  • the ductility and hardness of the bullet material of the finished projectile are in the order of magnitude of the starting material.
  • the bullet on the caliber 9 mm * 19 mm is therefore ideal for the ammunition of the police, military and law enforcement.
  • An inventive method for producing a projectile is characterized in that from the starting material of the projectile a Ge Schoss blank with a cylindrical rear part and a bow-side open hollow cylinder is made so that the wall thickness of the hollow cylinder from the rear end to the top steadily decreases and then the hollow cylinder is formed by a tumbling process to Ogiven Scheme, the blank and the projectile during the production of any thermal post be subjected. In a tumbling process, the material hardness of the bullet blank is increased only slightly. Only hereby the trajectory remains optimal.
  • Thermal aftertreatment means that the ready-made projectile is "thermally treated" once again, ie thermal aftertreatment means a thermal treatment on the ready-to-use bullet
  • Tumbling process lies precisely in the fact that the material properties are defined during the production of the raw material and are not significantly changed by the processing, the bullet molding.
  • the bullet blank is preferably machined but can also be used in cold or
  • Hot forming processes are produced.
  • the outer diameter D1 of the hollow cylinder at the tip is made to be smaller than the diameter D2 of the hollow cylinder at the rear end.
  • the hollow cylinder is thus conical. This simplifies the tumbling process.
  • the projectile according to the invention thus consists of a cylindrical rear part and an Ogiven Scheme having a cavity.
  • the wall thickness of the ogive or the ogive area and the resulting cavity should be chosen so that the bullet is stable enough to ensure a safe supply in the weapon and does not deform or splinter in the soft target (gelatin).
  • a projectile according to the invention preferably has the caliber 9 mm x 19 and is in terms of weapon function and its trajectory with the associated mission ammunition, z. B. ammunition gem. TR2009, identical and does not break through a protective vest SK1 (standard according to technical guideline of the German police).
  • the bullet blank is mainly made by machining, but can also be used in
  • the construction of the bullet blank already includes the wall thickness course of the ogive of the finished bullet.
  • the wall thickness is characterized in that it becomes smaller towards the tip, later the area undergoing the greatest deformation.
  • the ogive is formed by a tumbling process that produces the desired shape without unduly increasing the material hardness of the preformed blank.
  • the basic material structure is influenced much less.
  • ductility and hardness remain in the orders of magnitude of the starting material. Because of that
  • Blank already has a conical or ogival preform, the necessary forming work is reduced, so that the material hardness of the prefabricated blank is not increased.
  • the workpiece here the bullet blank
  • This die is clamped on the fixed part of a tumbling press. From above, with one or more rotating dies one after another, the workpiece becomes cold reshaped.
  • the upper die is inclined to its axis of rotation by a certain angle. This results in a rolling movement under which the metal of the workpiece can flow into its new shape.
  • Tumbling is akin to pushing. In contrast, however, much more complex shapes are possible. Tumbling or a tumbling process (sometimes referred to as radial rivets) is thus a cold forming process in which the forming force acts only on a partial surface of the workpiece. By a tumbling movement of the upper die on a rotationally symmetrical workpiece can be realized with relatively little effort a great transformation.
  • the projectile or bullet blank
  • the bullet has no predetermined breaking points. This means that the bullet 5 after the machining or the cold or hot forming process is neither subjected to a thermal aftertreatment nor does it have predetermined breaking points. This is important so that the ductility and hardness of the finished bullet remains in the order of magnitude of the starting material.
  • FIG. 1 shows a projectile blank 5 after being turned and before treatment by a tumbling process with a cylindrical rear part 1 and a bow-side hollow cylinder 6.
  • the hollow cylinder 6 has been hollowed out by turning and is open at the tip 7.
  • the wall thickness 9 of the hollow cylinder 6 decreases continuously from the rear end 8 to the projectile nose 7.
  • the outer diameter D1 of the hollow cylinder 6 at the projectile nose 7 is less than the diameter D2 of the rear end 8 of the hollow cylinder 6.
  • FIG. 2 shows the finished projectile 10 which, after being turned, was shaped as a machining operation by means of a tumbling process.
  • the Ogiven Scheme 2 is formed while a cavity 3 enclosed.
  • FIG. 3 shows a projectile 10 according to the invention captured after firing in a protective vest. It is essentially dimensionally stable and not splintered, the cavity is compressed. A projectile according to the invention when hitting a soft target (gelatin) does not deform and does not splinter and is therefore identical to the projectile according to FIG.

Abstract

L'invention concerne un projectile (10) pour cartouches de stand de tir et d'entraînement. Il est pourvu d'une partie arrière cylindrique (1) et d'une zone d'ogive (2) à l'avant, cette zone d'ogive (2) comportant une extrémité arrière (8) et une ogive (7). L'invention vise à ce que le projectile se comporte dans la cible souple comme un projectile classique à paroi pleine et à tête ronde, qu'il présente une faible production d'énergie dans la cible souple, qu'il ne présente ni déformation ni formation d'éclat et qu'il n'y ait pas d'effet de perforation dans les matériaux de protection des collecteurs de balle. A cet effet, selon l'invention, le projectile (10) est réalisé d'une seule pièce, la zone d'ogive (2) est fermée de tous les côtés et comporte une cavité (3), et l'épaisseur de paroi (9) de la zone d'ogive (2) diminue progressivement de l'extrémité arrière (8) à la pointe (7).
