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

1-7. -7. (canceled)

8. A method for producing a core for a projectile, comprising the steps of:

compressing at least one wire or wire section, wherein the wire or wire section comprises a lead-free material to form a cavity-free core, wherein the wire or wire section in the interior or on the outer diameter have at least one geometrical shape, and/or a specific predetermined breaking point are incorporated in the core during the compressing.

9. The method according to claim 8, wherein the core is compressed separately so as to form a cavity-free core and is subsequently anchored in the projectile or is inserted as a wire section directly into the projectile jacket and is compressed in the projectile jacket so as to form a cavity-free core.

10. The method according to claim 8, wherein a press punch that is structured on its pressing side is used for pressing.

11. The method according to claim 9, wherein a press punch that is structured on its pressing side is used for pressing.

12. The method according to claim 10, wherein the structuring comprises needles that penetrate into the core during pressing and thereby create the predetermined breaking points.

13. The method according to claim 11, wherein the structuring comprises needles that penetrate into the core during pressing and thereby create the predetermined breaking points.

14. The method according to claim 12, wherein the dividing capability is set via the length of the needles.

15. The method according to claim 13, wherein the dividing capability is set via the length of the needles.

16. The method according to claim 8, wherein the wires or wire sections have slots or holes in the interior, and/or have slots on the outer wire diameter that are incorporated from the outside.

17. The method according to claim 9, wherein the wires or wire sections have slots or holes in the interior, and/or have slots on the outer wire diameter that are incorporated from the outside.

18. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 8, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

19. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 9, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

20. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 10, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

21. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 11, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

22. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 12, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

23. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 13, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

24. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 14, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

25. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 15, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

26. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 16, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.

27. A dividing projectile or partially dividing projectile comprising at least one core with predetermined breaking points produced by the method according to claim 17, wherein the projectile, in addition to the core that has predetermined breaking points, has at least one solid core made from solid material without predetermined breaking points, wherein the core that has predetermined breaking points is arranged before or behind the solid core, partially dividing projectile, or only cores that have predetermined breaking points are arranged next to one another or one behind the other dividing projectile in the projectile.
