The specific embodiment
As shown in Figures 2 and 3, this artificial rain bullet detonator comprises fuze body, self-destructor, slide block interrupter and detonating primer.
Fuze body 1 is combined by the fuse steel body portion 1-1 of bottom and the injection-moulded plastic part 1-2 on top.
Self-destructor is made up of firing device, last alignment pin 10, last paper gasket 15, time-setting ring 16, last alignment pin 10 is contained in the profile dowel hole of time-setting ring 16, last paper gasket 15 installs to the upper surface of time-setting ring 16, the last alignment pin 10 of time-setting ring 16 is aimed at the last dowel hole of ignition seat 8 and is packed into.
Firing device is made up of ignition seat 8, igniter cap plug screw 11, igniter cap 12, flank attack pin 14, flank attack needle spring 13, the center of crossing at ignition seat 8 has a groove 8-1, on the ignition seat 8 symmetrical cylindrical hole is arranged, flank attack pin 14, flank attack needle spring 13, igniter cap 12 are housed successively, then dress igniter cap plug screw 11 on the igniter cap 12 respectively.
The slide block interrupter comprises detonator seat 3, flame detonator 17, centrifugal slider 4, back seat pin 5, back marshall springs 6, screw 9 and presses spiral shell 2, flame detonator 17 is housed in the center cylindrical hole of detonator seat 3, press the circumferential upper end face of spiral shell 2 that slide block slot is arranged, in centrifugal slider 4 is housed, back marshall springs 6, back seat pin 5 are housed in the center cylindrical hole of pressure spiral shell 2 successively, with screw 9 detonator seat 3 and pressure spiral shell 2 are coupled together at last.Centrifugal slider adopts thick 10# steel plate of 2.6mm or the punch forming of 20# steel plate.
Detonating primer 18 is made up of booster cup, cap and HMX booster explosive, and the HMX booster explosive is contained between booster cup and the cap, and pressing then forms.
Self-destructor is contained in the endoporus upper end of fuze body 1, and the paper gasket 7 down of packing into then is contained in the endoporus lower end of fuze body 1 to the slide block interrupter, and the threaded portion of detonating primer 18 is screwed in the internal thread hole of pressing spiral shell 2 then.
Assembling process of the present utility model is as follows:
Getting angry flank attack pin 14, flank attack needle spring 13, the igniter cap 12 of packing into successively respectively in seat 8 symmetrical two cylindrical holes, be screwed into igniter cap plug screw 11 then respectively, firing device; In slide block interrupter when assembling, be coated with flame detonator 17 the epoxy resin detonator seat 3 back point rivetings of packing into earlier, again successively will back marshall springs 6, back seat pin 5, centrifugal slider 4 pack into press spiral shell 2 after, tighten a detonator seat 3 and press spiral shell 2 to couple together with screw 9 at last, the slide block interrupter; The self-destructor assembling time will go up alignment pin 10, go up paper gasket 15 install to the firing device lower surface successively after, again the last dowel hole of time-setting ring 16 is aimed at alignment pin 10 and packs into, self-destructor; The fuze body 1 of at last self-destructor being packed into, following paper gasket 7 pack in the fuse body opening after navigating to fuze body endoporus top, being screwed into fuze body behind the pressure spiral shell threaded portion shellac of slide block interrupter, be screwed into behind the threaded portion shellac of detonating primer 18 then press the spiral shell internal thread hole safety type artificial rain bullet detonator.
The action principle of this fuse: during the inner trajectory, after propellant powder is excited by cannon, produce high temperature and high pressure gas, force bullet to move to gun muzzle along gun tube, igniter cap is motion backward under the effect of back seat inertia force, and striker head is instantaneous when arriving, its kinetic energy is considerably beyond the igniter cap excitation energy, igniter cap is excited, and the burning time batch pan, and time-setting ring takes fire; Meanwhile, back seat pin after back seat inertia force effect lower compression marshall springs to armed position, release slider, along with bullet when gun muzzle moves, the suffered centrifugal force of slide block is increasing, and its suffered resistance is more and more littler, when the suffered centrifugal force of slide block begins during greater than its suffered resistance to radially motion, and the suffered back seat inertia force of seat pin is still greater than its spring resistance after this moment, and back seat pin is unlikely to reply and the pinning slide block, slide block arming so far.During outer trajectory and the terminal ballistics, time-setting ring is lighted flame detonator by regular hour burning, simultaneously slide block under centrifugal action and can not reply, the flame detonator detonating primer that detonates, so far fuze function is finished.
