Intermediate for manufacturing projectiles of a deformable bullet, projectile, deformed projectile, tool for manufacturing the intermediate and method for manufacturing the intermediate
Intermediate for the production of a projectile in particular a deformable bullet, consisting of a ductile blank, which is cold-formed into the intermediate by means of pressing, a cylindrical solid base end section and a press end section with a central press recess incorporated by means of pressing and a wall limiting the press recess to form an ogival shaped tip, wherein the wall is formed with at least two slots extending in the axial direction of the intermediate, which separate at least two prongs in the circumferential direction of the intermediate, wherein the at least two slots extend by more than 10% of an axial total longitudinal extension of the intermediate from the wall end towards the base end section.
1. A method for manufacturing a projectile comprising a cylindrical, solid base end section and an ogive section connecting to the base end section as a single piece with a wall for circumferentially enclosing of a cavity and an opening centred at a tip of the ogive section with a maximum diameter of less than 20% of a calibre of the projectile defined by the base end section, the method comprising:
inserting a blank made of a ductile material into a cylindrical die;
inserting a press head formed according to a blade of a slotted screwdriver, wherein the maximum diameter of the blade is greater than the calibre of the projectile, into the die for creating an intermediate of the projectile, the intermediate of the projectile comprising a cylindrical solid base end section, a press end section with a central press recess, and a wall limiting the press recess, which is formed into an ogival shaped tip having an opening at a tip of the ogival shaped tip, wherein the wall is formed with at least two through slots, which limit at least two structurally separated wall sections in a circumferential direction; and
forming the press end section with the at least two structurally separated wall sections separated by the slots into an ogive section.
2. The method for manufacturing a projectile according to claim 1 , in which respective tips of sections of the wall are formed into a substantially circular opening, which is arranged at the tip of the ogive section and/or open towards the cavity, wherein a cross-section of the opening forms an elliptical, circular, rectangular or polygonal shape, a Y-shape, a star shape or an I-shape.
3. The method according to claim 1 , wherein the press head is formed according to a blade of an SL-type, a PH-type, or a PZ-type slotted screwdriver, wherein the maximum diameter of the blade is greater than the calibre of the projectile.
4. The method according to claim 3 , wherein the press head consists of a hardened material with a hardness greater than 55 HV 5.
5. A tool for pressing a blank made of a ductile material to manufacture the intermediate of the projectile according to the method of claim 1 , the tool comprising a cylindrical die configured to have the blank inserted therein and having an internal diameter corresponding the calibre of the projectile, and a press head formed according to a blade of an SL-type, a PH-type, or a PZ-type slotted screwdriver, wherein the maximum diameter of the blade is greater than the internal diameter of the cylindrical die.
6. The tool according to claim 5 , wherein the press head consists of a hardened material with a hardness greater than 55 HV 5.
