Definitions

  • Cutting charges are used, for example, to cut through iron plates, cables, bridge girders.
  • Cutting charges are symmetrical shaped charges.
  • the cutting charges are equipped with a cavity, which unfold their preferential effect in the plane of symmetry.
  • Cutting loads with a roof-shaped or semicircular insert are mainly used for military use.
  • DE-A-1946959 relates to a shaped charge with ogival deposits of progressive or degressive wall thickness. This insert is made in one piece.
  • the object of the invention is to provide a precise, precise insert in order to improve the cutting performance of cutting loads and to simplify manufacture and for inexpensive manufacture, in which no residues of the insert are present in the cut after blasting and where the deposits ultimately are accurate and economical are cheap to produce. Furthermore, these metal inserts must also be able to be installed quickly and precisely in the cutting charge housing.
  • the advantages of the invention are that the cutting performance is increased significantly, no remaining components of the insert remain in the cut after the explosion, the insert can be manufactured precisely and precisely, is inexpensive to manufacture and can be easily and conveniently installed in the cutting charge housing .
  • an explosive insert 1 is provided with a recess 2, on the surfaces 3, 4 of which plate-shaped inserts 5, 6 are glued.
  • the inserts 5, 6 consist of electrolytic copper. On the gable side, they lie against one another with the surfaces 7, 8.
  • the insert 14 and 15 according to FIG. 2 have an insert shape according to the invention with a sinusoidal cross section and different material thickness.
  • a cut 30 according to FIG. 3 which can be achieved by the insert described above with an explosive insert and a housing with an ignition device not described here shows the increase in performance compared to a cut 31 achievable by the prior art in a target block 32 according to FIG. 4.
