Definitions

  • the invention relates to a method and an apparatus for producing a rohrformige penetrator for a balancing projectile with splinter effect.

  • This ceramic powder is pressed in an isostatic pressing device to a green compact.
  • the Pressvorrich. tion consists in turn of a metal tube which is closed by a detachably arranged upper lid, wherein a part of the lid engages in a flexible tube which is inserted in a tubular sealing rubber.
  • the sealing rubber stores the flexible tube in the center of the metal tube.
  • the metal tube has an opening at the side for the pressure inlet. From below, the metal tube is provided with a hole possessing metal lid. Through this lower lid, the ceramic powder located in Matrizen is introduced into the device and this closed. Then the flexible tube is pressed against the dies and the latter against the powdered ceramic via the lateral pressure inlet.
  • the pressing process takes place hydrostatically.

  • a first tungsten-like powder mixture with high tungsten content is filled in the inner tube to produce the penetrator core
  • a second tungsten-containing powder mixture is introduced into the annular space, which has a lower tungsten content than the other powder mixture.
  • a powder mixture is pressed into a pressed body, the body is then sintered.
  • a further step is then carried out the cold forming of the compact and the finishing of the Penetratorrohlings.
  • the GB 2 165 483 A describes an apparatus and method for producing a pressed tubular body having a groove on its outer surface.

  • Sintering is done with an internal medium in the blank, which can be easily removed after sintering.
  • the material properties are set by the alloy composition and characterized by heat treatment and, if necessary, mechanical deformation.

Centering 7 and filling tube 5 are firmly connected. It is filled in between a press die 3 and 4 filling spacer space 8.
  • the filling device Fig. 1b placed in a hydrostatic pressing system (not shown in detail, as known) and at a pressure of about 1500 bar, the metal powder mixture is pressed into a green compact. This has after removal from the filling device Fig. 1b the shape of a unilaterally sealed tube and can be handled without breaking.
  • the pressed tubes are then sintered in one or more passes in an oven (pre-sintering at a temperature between 1400 ° C and 1490 ° C, resintering at a temperature between 1495 ° C and 1570 ° C), so that from the compact workpieces with solid properties getting produced.

  • the solids are subjected to a heat treatment after the sintering.
  • a heat treatment after the sintering.
  • eg tensile strength, elongation at break and constriction can be adjusted.
  • This is preferably carried out in an annealing process, in which the annealing in a high vacuum below the melting temperature of the binder leads to a phase transformation, which leads to the subsequent quenching, for example in N 2 for fixing the material state and thus the material properties.
