Abstract

The invention relates to a method for producing a core (1) for a projectile (2). So that the dividing behavior of the projectile can be set in a simple manner, wherein the core is lead-free, it is proposed that one or more wires or wire sections composed of a lead-free material are compressed to form a cavity-free core (1), wherein the wires or wire sections have one or more geometrical shapes (3) in the interior or on the outside diameter and/or predetermined braking points (4) obtained during the compression are provided in the core (1).

Claims

1. A method comprising the steps of: compressing a wire or wire section wherein the wire or wire section comprises a lead-free material to form a core for a projectile, wherein prior to the compressing the wire or wire section has holes in an interior of the core of the wire or wire section, wherein said holes have the same diameter and, wherein the core is cavity-free.

2. A method according to claim 1, wherein there are nine said holes, wherein one of said holes is a central hole and is surrounded by eight holes.

3. A method for producing a core for a projectile, comprising the steps of: compressing a wire section wherein the wire section comprises a lead-free material to form a core, wherein prior to the compressing the wire section has holes in an interior of the core of the wire section, wherein said holes have the same diameter, wherein after said compressing the holes no longer remain in the core and the core is cavity-free.

Description

(1) The invention is explained in greater detail by means of exemplary embodiments.

(2) In the figures, schematically:

(3) FIG. 1 shows a core that has axial predetermined breaking points.

(4) FIG. 2 shows a core that has radial predetermined breaking points.

(5) FIG. 3 shows a core that has axial and radial predetermined breaking points.

(6) FIG. 4 shows a semi-jacketed projectile as a partially dividing projectile, one half illustrated in a cross-sectional view, comprising a solid tail core and a tip core with interspersed predetermined breaking points.

(7) FIG. 5 shows a dividing projectile that has a core interspersed with predetermined breaking points.

(8) FIG. 6 shows a core comparable to that in FIG. 2. The difference is that a plurality of dividable cores, preferably between 2 and 20 pieces, are arranged on top of each other and are pressed together.

(9) FIGS. 7a-c shows examples for shapes incorporated into the Pb-free wire.

(10) FIG. 8 shows a projectile core that has predetermined breaking points extending in the longitudinal direction and a dividing rate of 100%.

(11) FIG. 9 shows a projectile core that has predetermined breaking points extending in the longitudinal direction and a dividing rate of 10%.

(12) FIG. 10 shows a projectile jacket with a projectile core that is compressed in the projectile jacket and has predetermined breaking points extending in the longitudinal direction and a dividing rate of 10%.

(13) FIG. 11 shows a projectile jacket with a projectile core that is compressed in the projectile jacket and has predetermined breaking points extending in the longitudinal direction and a dividing rate of 100%.

(14) In FIG. 1, the predetermined breaking points 4 provided in the core 1 are arranged in the axial direction; they are created by compressing the wire comprising the incorporated shapes.

(15) FIG. 2 corresponds to FIG. 1, but with radial predetermined breaking points 4.

(16) FIG. 3 corresponds to FIG. 1, but with axial and radial predetermined breaking points 4.

(17) In FIG. 4, a semi-jacketed projectile or partially dividing projectile 2a is illustrated. In the initially undeformed open projectile jacket 5, a solid core 8 from a material suitable for a projectile core was inserted. A core 1 with predetermined breaking points 4 was pressed on top of the solid. All Pb-free (lead-free) compressible materials are suitable as materials. Subsequently, the projectile jacket 5 was necked so as to form the illustrated projectile shape. The projectile jacket 5 is not closed at the projectile tip.

(18) When shooting, after opening the projectile jacket, the pressed core 1 with the predetermined breaking points 4 divides into its individual parts and thereby transmits the desired energy into the game. From shot to shot with the same caliber, projectile weight, speed and distance, the energy output by the pressed core 1 into the game is always the same. This type of projectile is speed-independent because the pressed core 1 divides itself at high or low speed.

(19) The proportions in terms of size of the two cores 1, 8 depend on the desired shock effect and penetration into the game body.

(20) At a 50% weight proportion of the pressed core 1, which has the predetermined breaking points 4, based on the total weight of all cores 1 and 8, a high shock effect with a penetration according to the size of the individual parts is obtained.

(21) At a 20% weight proportion of the pressed core 1, which has the predetermined breaking points 4, based on the total weight of all cores 1 and 8, a low shock effect with a penetration according to the size of the individual parts is obtained, but with less destruction of game.

(22) The exemplary embodiment according to FIG. 2 (dividing projectile) is comparable with FIG. 1 in terms of the mode of action. The difference is that the core is one piece and the projectile divides itself completely.

(23) The embodiment of FIG. 3 is comparable with that of FIG. 2. The difference is that the projectile core consists of a plurality of cores that have interspersed predetermined breaking points 4 arranged one above the other. The advantage is that the subdivided whole core 1 divides itself in smaller individual parts.

(24) FIG. 5 illustrates a jacket projectile in which a single core 1 that has predetermined breaking points 4 is arranged.

(25) FIG. 6 illustrates a jacket projectile in which three cores 1 that have predetermined breaking points 4 are arranged. As in FIG. 5, no solid core without predetermined breaking points is arranged in the projectile.

(26) FIGS. 7a to 7c show endless wires or wire sections 12 with different cross-sections with incorporated geometrical shapes. FIG. 7a shows nine holes or channels 9 formed therein. All holes or channels 9 have the same diameter, wherein a central hole or a central channel 9 is surrounded by eight holes or channels 9. FIG. 7b shows four slots 7 formed therein and FIG. 7c shows eight slots 10 on the outer wire diameter 11.

(27) The dividing of a projectile in the target body, in particular of a hunting projectile in the game body after penetrating into the game body, determines the energy output and thus the effect of the shot. A compressed projectile core from Pb-free material held by the projectile jacket and interspersed with predetermined breaking points divides itself together with the projectile jacket upon impact on the target body. The size of the individual parts determines the energy output and the predetermined breaking points in the projectile core determine the size of individual parts that result from the dividing of the projectile core and thus determine the effect of the projectile.

(28) FIG. 8 shows a projectile core 1 that has predetermined breaking points 4 running in the longitudinal or axial direction, which predetermined breaking points protrude completely through the projectile core 1. The dividing rate is 100%.

(29) FIG. 9 shows a projectile core 1 that has predetermined breaking points 4 running in the longitudinal or axial direction, which predetermined breaking points protrude into the projectile core 1 in the longitudinal direction or axial direction only up to a depth of 10%. The dividing rate is 10%.

(30) FIG. 10 shows a projectile jacket 5 with a projectile core 1 that is compressed in the projectile jacket and has predetermined breaking points 4 extending in the longitudinal direction and a dividing rate of 10%.

(31) FIG. 11 shows a projectile jacket 5 with a projectile core 1 that is compressed in the projectile jacket 5 and has predetermined breaking points 4 extending in the longitudinal direction and a dividing rate of 100%.
