Definitions

  • the invention relates to a method for producing a detonator tube open on both sides for a hand grenade detonator, in which a detonator charge is only ignited if a delay charge is contained in the detonator tube.
  • the delay charge in the detonator tube causes the detonation to be delayed after the hand grenade is thrown away, in which the safety clip is thrown off and the primer is acted upon, in order not to endanger the launcher.
  • a jet of fire emerges from the open tube end and initiates the detonator charge (for example according to US Pat. No. 2,562,928).
  • the primer is not or only insufficiently filled with the delay charge.
  • the fire jet emitted by the primer hits the detonator charge in the first case, so that the hand grenade detonates immediately when it is thrown off, in the second case the delay charge, but the delay is too short and the hand grenade detonates during the flight.
  • AT-B-335 314 does not provide a locking washer as a termination of the ignition tube for the detonator charge, which is dimensioned such that it melts only when the lowest part of the delay charge is ignited however, if this is missing and the spray of fire hits the safety washer from the primer.
  • the ignition of the detonator charge in the presence of the delay charge is therefore dependent on the material properties of the locking washer.
  • test piston now sinks too far into the load carrier when the fill level is too low, the magnetic poles of the same name of the two magnets come so close that the horizontally displaceable magnet is ejected, thereby locking the carrier plate so that the insufficient fill level is not only due to the different levels Heights of the test piston, but can also be recognized by the blocking of the carrier plate.
  • a further work step is not controlled by this, but it only recognizes the operator that there are load carriers with an insufficient fill level.
  • the invention therefore has for its object to provide a method for producing error-free, double-sided ignition tubes, in which the ignition of the detonator charge can not be initiated directly from the primer beam, but exclusively from the delay charge, but this is not only from Presence of a filling, but also depends on the correct filling level and compression.
  • this is achieved in that the delay charge is filled into a one-sided ignition tube and then the fill level is measured, with a test piston being inserted into the ignition tube up to the desired fill level after filling the delay charge and a punch being applied to the bottom part of the tube, whereupon the distance is reduced between the test piston and the punch, whereby, depending on the actual fill level, the ignition tube is either pushed onto the punch with perforation of the base part or further onto the test piston, so that the base part of the ignition tube is only punched if the delay charge is sufficiently full.
  • a hand grenade detonator (FIG. 1) has an ignition tube 1 with a delay charge 3 filled in, which has been introduced, for example, into three layers 3 ', 3 ", 3'".
  • the ignition tube 1 is open on both sides, a percussion cap 6 being placed on the upper end.
  • the second end of the ignition tube 1 has an opening 4 in the base part 2.
  • a carrier tube 7 for a detonator charge 5 is plugged onto the second end. After the striking cap is ignited by a spring-loaded striking piece, a jet of fire ignites the delay charge 3, which is filled up to the filling level a which ensures a sufficient delay. After the delay charge 3 has burned off, the detonator charge 5 is ignited by the fire jet emerging through the opening 4.
  • the firebeam of the primer 6 falls directly onto the detonator charge 5, so that the hand grenade detonates immediately; if it does not have the correct fill level a, there is too little delay, so that the hand grenade detonates in the air during the throw. Both cases should be avoided if possible.
  • the method according to the invention now provides the perforation of the base part 2, that is to say the formation of the opening 4, only when the delay charge 3 has been filled in in the correct amount, ie that is, if all layers 3 ', 3 ", 3"' are contained in the ignition tube 1 in the exemplary embodiment (FIG. 2).
  • the ignition tube 1, which is closed on one side can, for example, as shown in FIGS. 1 to 3, have an integrated base part 2; the bottom part 2 can also be used subsequently. 4 and 5, for example, such ignition tubes are shown.
  • the bottom part 2 is formed by a disc 14 which is held by a flanged retaining ring 13.
  • 5 shows an ignition tube 1 with an opening 4 on the detonator charge side, which is closed before the delay charge 3 is filled in by a cup-shaped insert 15, which is supported on the inwardly thickened wall region 16 of the ignition tube 1 surrounding the opening 4.
  • the ignition tube 1 is placed on a test piston 8 arranged on a base 10, whereby it penetrates into the ignition tube 1 up to the desired filling level a.
  • a punch 9 protruding from the lowerable upper part 11 is placed on the bottom part 2 of the ignition tube and finally moved further downward, so that the distance between the test piston 8 and the punch 9 is reduced.
  • the delay charge 3 has the correct fill level a (FIG. 2), then it acts as an extension of the test piston 8, d. that is, the punch 9 pierces the base part 2 or the disk 14 or the insert 15 to form the opening 4.
  • the ignition tube 1 with an integrated base part 2 is made of nickel-plated brass.
  • the disc 14 and the cup-shaped insert 15 can also consist of a copper-free aluminum-silicon-magnesium alloy.
