Definitions
- the invention relates to a method for producing an open-ended ignition tube for a hand grenade detonator, in which a detonator charge is only ignited if a delay charge is contained in the ignition tube.
- the delay charge in the primer tube causes the detonation to be delayed after the hand grenade is thrown away, in which the safety bracket is thrown 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 flight.
- the AT-PS 335.3-14 does not provide a safety 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. Ignition of the detonator fertilizer in the presence of the delay charge is therefore dependent on the material properties of the locking washer. In addition, there remains the problem of the incompletely filled ignition tube, in which the delay charge is too low and therefore the delay time is too short.
- the object of the invention is therefore to create a method for producing fault-free ignition tubes, in which the detonator charge cannot be initiated directly by the primer spray, but only by the delay charge, this not only from the filling but also also depends on the correct filling level of the deceleration charge itself.
- this is achieved in that the delay charge is filled into a one-sided ignition tube and then the fill level is measured, whereupon the bottom part of the ignition tube is perforated only if the delay charge is of sufficient fill level.
- a test piston is inserted into the ignition tube up to the desired filling level and a punch is placed on the bottom part thereof, whereupon the distance between the test piston and the punch is reduced, depending on the actual one Filling level, the ignition tube is either pushed onto the punch with holes in the bottom part or further onto the test piston.
- FIG. 1 shows a longitudinal section through a hand grenade detonator
- Fig. 2 shows the punching process up to the desired fill level . filled ignition tube according to the invention
- Fig. 3 shows the corresponding operation with insufficient level
- a hand grenade detonator (FIG. 1) has an ignition tube 1 with a delay charge 3 filled in, which has been introduced in three layers 3 ', 3 ", 3"' for example.
- 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 has been ignited by a spring-loaded striking piece, the fire jet 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 spray 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 han grenade detonates while in the air. Both cases should be avoided if possible.
- the method according to the invention now sees the perforation of the base part 2, that is to say the formation of the opening 4. finally before when the delay charge 3 has been filled in in the correct amount, ie when in the exemplary embodiment all layers 3 ', 3 ", 3"' are contained in the ignition tube 1 (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, however, be retrofitted. 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 opening 4 on the detonator charge side in the ignition tube 1, 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 area 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 bottom part 2 or the disk 14 or the insert 15 to form the opening 4.
- the ignition tube 1 preferably has an integrated base part 2 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.
- the checking of the filling level a can also be carried out in a different way, the ignition tube not being supplied to the perforation if the filling height b is too low.
