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 powder form by the impact forces.
• the core By disassembling the core, most of the energy in the target projectile is lost. In addition to preventing excessive damage to the target by disassembling, this primarily prevents the practice floor from bouncing off the target and possibly injuring people on the training area.
• a cutting projectile 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 known cutting heads are not reliably disassembled, particularly in the event of an oblique impact. An oblique impact does not only occur if the direction of flight of the practice floor is at an angle to the target; rather, the light practice projectiles sometimes tumble around the direction of flight so that they can hit the target at an angle even when firing directly.
• 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 at an oblique impact on a target, 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 significantly 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 exercise gene strikes the impact forces always run through the center of the ball and result in almost the same breaking 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 attachment 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 3.
• 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 inserted on its top side facing the tip 5 of the cutting head 1 brings.
• 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 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.
• the exemplary embodiment according to FIG. 2 differs only from the above in that the notch here denoted by 6 'is cylindrical. Other configurations are also possible.
• the ball 7 has a correspondingly larger diameter than the notch 6 '.
• the embodiment according to FIG. 3 differs from that according to FIG. 1 in that the ball 7 'is composed of several parts, in this case two halves A and B, which are lightly glued together, for example by an adhesive 8. This gluing makes it easier to manipulate the ball when assembling the cutting head.
• the spherical halves separate. Since ball halves have a higher air resistance than solid balls, the ball halves are thrown less far away than solid balls when bouncing off from a target, for example.
• the position of the separating seam between the two spherical halves in relation to the central axis of the recess is otherwise for the disassembly irrelevant. In Fig. 3, the angle between the seam and the central axis is shown at about 45 °.
