Definitions

  • the invention relates to a projectile-forming insert for shaped charges and to a method for producing the insert.
  • the invention is therefore based on the object of providing an insert and a method for its production which can be produced with little effort and which permits a reproducible design of the stub wings on the projectile.
  • the invention solves this problem according to the characterizing features of claim 1 and according to the features of the method claim. It is essential for the invention that the projectile is without the usual rear cavity.
  • a flat, dome-shaped insert 1 with star-shaped narrow zones 2 has recrystallized material. These zones 2 are heat-treated and / or melted and thus recrystallized by a laser or electron beam.
  • the restructuring of the structure in precisely defined zones 2 lowers the hardness and the yield point and introduces compressive stresses in the direction of folding. This structural restructuring takes place symmetrically to the main axis 5 of the insert 1.
  • a flat, dome-shaped insert 10 is provided with narrow zones 2, 3 of recrystallized material which are formed in a star shape. These zones 2, 3 are not only introduced on one side of the insert 10 as in FIG. 1, but zones 2, 3 of recrystallized material are alternately produced on both sides of the insert 10. This structural transformation also takes place symmetrically to the axis 5 of the insert 1.
  • the front zones 2 visible according to FIG. 2 form the outer edges of the stub wings 8 and the rear zones 3 form part of the wing base 9 of the projectile 6.
  • the projectile 7, based on the insert according to FIG. 2 is based on an insert, not shown, with eight mutually lying zones 2, 3.
  • a sixfold fold is formed in accordance with the recrystallized symmetrical zones 2, 3. This fold can be specifically adjusted by the extent, depth, number and symmetry of the structure of zones 2 recrystallized by laser or electron beam.
  • the targeted folding also results in a stable flight phase of the projectile 6, 7 shown from the beginning of the shaping process, thereby increasing its end ballistic performance and increasing the accuracy of the target.
  • Suitable materials for the insert are Armco iron, tantalum or copper.
