Definitions

  • the invention relates to a disassembly projectile head for practice ammunition according to the preamble of the claim
  • a disassembly projectile head for practice ammunition for recoil-free weapons which consists of a core of pressed or sintered metal powder and a hood surrounding it, e.g. consists of metal or plastic, which is conical at the front, in the area of impact, with a flattened tip.
  • the practice bullet hits the target with the cutting head, generally an iron plate
  • the hood bursts and the core is broken down into almost powder form by the impact forces.
  • the majority of the energy of the training floor hitting the target is reduced. Apart from the fact that disassembly prevents excessive damage to the target, this primarily prevents the practice floor from bouncing off the target and possibly injuring people on the training area.
  • a decomposing projectile is known in which the core of brittle material is provided with a continuous bore into which a wedge is inserted, which is driven into the bore upon impact of the projectile onto a target, whereby the Core disintegrates.
  • This wedge splits the core, so to speak, which brings better cutting results when impacting a target than with the cutting head above, but these results are not optimal.
  • the invention has for its object to modify a disassembly projectile head of the type in question by simple measures so that the projectile head is reliably disassembled even when it strikes a target at an angle, so that rebounds are avoided.
  • a simple ball is inserted as a transmission body between the hood and the core of the cutting floor, which sits on the recess.
  • the results are much better than with wedge-shaped transmission bodies and also with transmission bodies which have a hemisphere in their area facing the core and a shape adapted to the inner wall of the hood in the manner of a pyramid in their area facing the hood.
  • a ball as a transmission body, which rests on the inner wall of the hood and the upper edge of the notch in the core, has the advantage that when the practice floor hits the impact forces always run through the center of the ball on the target and result in almost equally large decomposition forces for all impact angles. This also reliably disassembles the core in the event of an extreme oblique impact of the training floor on the target.
  • the recess or notch can be cylindrical, for example. Very good results are achieved with tapered notches.
  • a cutting head 1 has a base 2 for fastening in a training floor (not shown), furthermore a cylindrical core 3, which rests on the base 2 and a thin hood 4 connected to the base 2 and comprising the core 1.
  • the hood 4 tapers e.g. conical in its area protruding beyond the core 3 and has a flattened tip 5.
  • the longitudinal axis of the cutting head 1, at the same time the central longitudinal axis of the core 3 and hood 4, is denoted by A.
  • a notch 6 in the form of a truncated cone tapering downward about the axis A is made on its upper side facing the tip 5 of the cutting head 1.
  • a ball 7 is inserted into the notch 6, which preferably dips into the notch 6 to such an extent that the center of the ball lies just above the upper edge of the notch 6 and the notch touches the ball 7 tangentially in the region of its upper edge.
  • the ball 7 lies in the area of the tip 5 and part of the conical taper on the inner wall of the hood 4.
  • the ball has a diameter of approximately two thirds of the core diameter, the depth of the notch corresponds approximately to the diameter of the ball, the diameter of the notch on the bottom is approximately one third of the core diameter.
  • the ball 7 When the cutting head 1 hits a target, the ball 7 is driven into the notch 6.
  • the core 3 is split with a force corresponding approximately to the impact force and disassembled when the hood 4 bursts open.
  • FIG. 2 differs only in that the notch here designated 6 'is cylindrical. Other configurations are also possible.
  • the ball 7 has a correspondingly larger diameter than the notch 6 '.
  • FIG. 3 differs from that of FIG. 1 in that the ball 7 'is composed of several parts, in this case two halves A and B, which are easily glued together, for example by an adhesive 8. This bonding makes it easier to manipulate the ball when assembling the cutting head.
  • the spherical halves separate. As ball halves have a higher air resistance than solid balls, the ball halves are thrown less far away from a target board than solid balls when bouncing off. The position of the separating seam between the two ball halves in relation to the central axis of the recess is otherwise for the disassembly irrelevant. In Fig. 3 the angle between the separating seam and the central axis is drawn in at approximately 45 °.
