Description

Steel plastic combined artificial rain bullet detonator

Technical field

The invention belongs to the artificial rain bullet detonator technical field, particularly a kind of steel plastic combined artificial rain bullet detonator.

Background technology

The fuse (hereinafter to be referred as former fuse) of hail mitigation bullet of applying at present to increase rain artificially is made up of side firing device, time-delay self-destructor, detonating primer, fuze body etc., feedback information by the user, that the problem that exists mainly shows as is half quick-fried, misfire, explosion residue fragmentation quality are bigger than normal, has potential safety hazard.Through verification experimental verification, the present people's rain fuse that uses mainly is that the energy of output is too small, is not enough to detonate or the bullet that detonates fully because the propagation of explosion energy does not match, and causes artificial rain bomb's misfire or partly quick-fried.And explosion residue fragmentation quality bigger than normal mainly be that weight is excessive causes because fuze body adopts all steel fuze body and gets angry seat, as shown in Figure 1,1 fuze body, 2 ignition seats, test shows, after the bullet blast, because the transmission of detonation wave is successively decreased, the fuze body head can not be scraped fully, its remaining fragmentation quality is greater than 100g, the seat of getting angry can not be scraped, its quality surpasses safety index and requires the existence of 15g. owing to the problems referred to above greater than 20g, can cause serious injury to people, livestock, building etc. in the operation process of increasing rain artificially.

Summary of the invention

The objective of the invention is to solve increase rain artificially at present now that the hail mitigation bullet exists half quick-fried, the misfire rate is higher, explosion residue fragmentation quality safety problem bigger than normal, a kind of steel plastic combined artificial rain bullet detonator that improves structure is proposed, after the artificial rain bomb is normally detonated, the remaining fragmentation quality of artificial rain bomb is little, falls Shi Buhui and damages.

Technical solution of the present invention is as follows: steel plastic combined artificial rain bullet detonator is made up of side firing device, time-delay self-destructor, detonating primer, fuze body.The side firing device is contained in fuze body endoporus top with the time-delay self-destructor, and detonating primer is contained in fuze body endoporus bottom.Described fuze body is partly combined by the fuse steel body portion of bottom and the injection-moulded plastic on top, the injection-moulded plastic on fuze body top partly is injection-moulded on the fuze body steel body for modification strengthens nylon SL-007, its injecting condition is that plastic material is preheated to 85 ℃ ± 5 ℃ behind dry 16h～24h earlier, again fuze body steel body portion is preheated to 85 ℃ ± 5 ℃ earlier, under injection machine 90MPa～110MPa pressure, carries out injection moulding.

The side firing device mainly comprises ignition seat, side igniter cap, flank attack pin, flank attack needle spring, igniter cap plug screw etc., and the time-delay self-destructor mainly comprises batch pan, bracket, middle detonator etc., and the center of crossing of ignition seat has a groove.Middle detonator is equipped with 611 little cigarette medicines, and its pressing quality is 53mg～58mg.Pressing has the plumbous circle of sealing on the cylindrical of the bottom of detonating primer.

The present invention has following effect:

By fuze body being designed to the structure that steel is moulded combination, change the fuze body head into plastics by steel, its weight is reduced to 6 grams by more than 100 grams, by improvement to the ignition seat, on former ignition seat basis, milled a deep trench, can alleviate its quality like this and can not influence the performance of fuse, above-mentioned measure has solved the artificial rain bomb's remaining fragmentation quality in back problem bigger than normal of exploding fully.By middle detonator Central Plains is replaced with 611 ignition powders with 634 ignition powders, solved the propagation of explosion energy and crossed minor issue, thereby solved half quick-fried, the misfire problem that present artificial rain bomb exists.

The specific embodiment

As shown in Figures 2 and 3, this steel plastic combined artificial rain bullet detonator is made up of fuze body, side firing device, time-delay self-destructor and detonating primer.

Fuze body 1 is divided into the steel body portion 1-1 of bottom and the injection-moulded plastic part 1-2 on top, the steel body is divided into steel machine add-on type No. 30, upper plastic is by injection mo(u)lding, plastic material is that modification strengthens nylon SL-007, its injecting condition is that parts of plastics is preheated to 85 ℃ ± 5 ℃ behind dry 16h～24h earlier, again fuze body steel body portion is preheated to 85 ℃ ± 5 ℃ earlier, under injection machine 90MPa～110MPa pressure, carries out injection moulding.

The time-delay self-destructor by last alignment pin 13, go up paper gasket 4, batch pan 3, down paper gasket 5, adjust paper washer 7, alignment pin 10, middle detonator 12 and bracket 6 are formed down, last alignment pin 13 is contained in the dowel hole of batch pan 3, last paper gasket 4 installs to the upper surface of batch pan 3, the last dowel hole of the last alignment pin 13 of batch pan 3 being aimed at ignition seat 2 is packed into again, batch pan is for 3 times a bracket 6, be equipped with in the centre bore of bracket 6 and adjust paper washer 7, middle detonator 12, alignment pin 10 is housed down in the dowel hole, paper gasket 5 is housed down above the bracket 6.

The side firing device is made up of ignition seat 2, igniter cap plug screw 16, side igniter cap 17, flank attack pin 14, flank attack needle spring 15, the center of crossing of ignition seat has a groove A, the cylindrical hole that symmetry is arranged on the ignition seat 2, flank attack pin 14, flank attack needle spring 15, side igniter cap 17 are housed successively, then dress igniter cap plug screw 16 on side igniter cap 17 respectively.

Detonating primer is made up of booster cup 9, detonating primer lid 8 and Tai'an booster explosive, and Tai'an booster explosive is contained between booster cup 9 and the detonating primer lid 8, and pressing then forms.

The assembling of this fuse process as follows:

The assembling of time-delay self-destructor the time will go up alignment pin 13, go up paper gasket 4 install to the firing device lower surface successively after, again the last dowel hole aligning of batch pan 3 being gone up alignment pin 13 packs into, at first pack at bracket 6 centre bores and to adjust paper washer 7, detonator 12 in the middle of reinstalling, alignment pin 10 under dowel hole is packed into earlier under 6 liang of symmetries of bracket, to play the following alignment pin 10 of paper gasket 5 alignings to pack into again and put in place, the following dowel hole that the following alignment pin 10 of bracket 6 is aimed at batch pans 3 is packed at last; Self-destructor and the side firing device combination fuze body endoporus of packing into of then will delaying time, be screwed into the fuze body endoporus behind the threaded portion shellac with detonating primer then, the plumbous circle 11 of last indentation sealing in the column part lower end of booster cup 9 steel mould the mating type artificial rain bullet detonator.

Action principle is as follows: during shooting, after propellant powder is lighted, produce high temperature and high pressure gas, force bullet to move to gun muzzle along gun tube, igniter cap is motion backward under the inertia force effect of recoil, the bump firing pin, igniter cap is excited, and lights batch pan, batch pan takes fire, detonate detonating primer and to bullet output detonation wave of detonator in the middle of igniting by regular hour burning, middle detonator, so far fuze function is finished.
