Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Mini-type detonation train of the present invention comprise alms giver's powder charge 1, film flying 2, slide plate 3, by main charge 4, alms giver's powder charge 1 and being realized by metal film flying 2 by the energy transferring between main charge 4, by in alms giver's powder charge 1 and by inserting flame proof slide plate 3 between main charge 4, the sequence that makes to detonate has flame proof function.Compared with existing sequence of detonating, the present invention has the advantages such as powder charge explosion velocity is high, volume is little, reliability is high, required driving-energy is low.
During concrete enforcement, alms giver's powder charge 1 and are explosives of two cylindrical shapes by main charge 4, film flying 2 is disc-shaped structures.Outside powder charge, have metal shell, difference is larger along with the difference in application place for the shape of metal shell and thickness.
Slide plate 3 be fixedly realizing by security mechanism, this security mechanism does not belong to content of the present invention, this technology comparative maturity, " Tanaka is prosperous for the security mechanism that the present invention adopts and document, Zhao Xu, Song Yongqiang, Liu Zhanheng, Li Xiaojie. improve MEMS flame-proof mechanism cantilever beam and the dop [J] of intensity. detection and control journal, 2011, (05) similar: 1-4+9 ", slide plate 3 (the flame proof slide block namely in document) just in the present invention is thinner, upper at described security mechanism, have cover plate, alms giver's powder charge 1 in Fig. 2, film flying 2 and by main charge 4 be all be assemblied on these cover plates, like this, alms giver's powder charge 1, film flying 2, slide plate 3, finally be connected to one by main charge 4 and form a part.Alms giver's powder charge 1, film flying 2 are identical with being subject to the diameter of main charge 4, and slide plate 3 is not circular, and its area should be greater than the area of film flying 2.
The present invention adopts the design of attenuation effects-miniature slide plate explosion separation structure, and when Mini-type detonation train of the present invention is in arming state, as shown in Figure 2, now slide plate 3 is positioned at cavity side, film flying 2 and not intercepting by between main charge 4.When alms giver's powder charge 1 is detonated, because film flying 2 is close to alms giver's powder charge 1 (when specifically implementing, film flying 2 is bonded and fixed in alms giver's powder charge 1 by binding agent), under detonation product effect, film flying 2 is accelerated rapidly, and flies to along cavity to by main charge 4.When film flying 2 touches by main charge 4, because the percussion of film flying 2, by the pressure inspired in main charge 4 far above explosive Impact Initiation pressure, be therefore detonated by main charge 4, detonation wave continues forward direction along powder charge passage.That is, the present invention utilizes alms giver's explosive 1 driven flyer plates 2, is carrier diffusion energy with film flying 2, and when film flying 2 clashes into acceptor's explosive 4, in acceptor's explosive 4, incident blast wave realizes energy transferring.
When sequence of detonating is in safety position, as shown in Figure 1, slide plate 3 is positioned in the middle of cavity, even if alms giver's powder charge 1 is surprisingly detonated, the energy of film flying 2 can not pass to by main charge 4, that is utilizes alms giver's powder charge 1 and stops film flying 2 to move by the slide plate 3 between main charge 4, as shown in Figure 3, thus stop the propagation of energy, play the effect of flame proof.
The detonation wave of Small dimension charge is low by transfer of air energy efficiency in the cavities, if diameter is the Small dimension charge of 1mm, after the decay of the vast sky chamber of 1mm, detonation wave cannot detonate cavity below by main charge 4.By film flying 2 transferring energy, then efficiency comparison is high, as the film flying 2 be made up of titanium sheet, stainless steel and ambrose alloy, still can be subject to main charge 4 by reliable initiation when the length of cavity is 2mm.Therefore the present invention adopts attenuation effects to design.
Material, the thickness of the speed of film flying 2 and the quality of alms giver's powder charge 1 and film flying 2 are relevant.For a certain material film flying 2, the quality of alms giver's powder charge 1 is larger, and the speed of film flying 2 is then larger.Film flying 2 of the present invention can adopt titanium or stainless steel or these three kinds of materials of ambrose alloy, the thickness of film flying 2 is 1 ~ 1.5mm, the thickness of film flying 2, through optimal design, to ensure can reliably ignite acceptor's explosive under arming state, can realize reliable flame proof under safety position.
The initiating ability of sequence of detonating is relevant with the kind of powder charge, and the explosion velocity of explosive is higher, and degree of packing is larger, then detonation pressure is higher, and the initiating ability of powder charge is stronger.Charge diameter in addition due to Mini-type detonation train is less, needs the explosive adopting cut off diameter less.The present invention's alms giver's powder charge used and all adopt J0-9C type fine grained booster explosive by main charge, degree of packing is 1.707 ± 0.005g/cm
3(90%TMD) (TMD refers to maximum theory density), for ensureing Powder pressing density and avoiding density gradient, adopts the method for location pressing several times that powder column is compressing.Alms giver's powder charge of the present invention and be 0.9 ~ 3mm by the diameter of main charge, explosion velocity of explosive of the present invention can reach and be greater than 7000m/s, and existing powder charge is difficult to reach this speed when diameter is 0.9 ~ 3mm.
Experimental study shows, when the thickness of cavity is 1mm (refer to alms giver's powder charge 1 bottom to the distance of the top by main charge 4), the speed of film flying 2 (point to reach by main charge 4 time speed) more than 95% of its maximal rate can be reached (after film flying 2 leaves alms giver's powder charge 1, its speed also can continue to increase, maximal rate refers to if not by main charge 4, film flying 2 moves the maximal rate that can reach in the cavities), therefore the thickness of selected cavity is 0.9 ~ 1.2mm.
The thickness of metal slide plate 3 is 0.6 ~ 1mm, and in this thickness range, slide plate effectively can stop the motion of film flying, prevents acceptor's explosive 4 to be detonated.Slide plate 3 utilizes sheet metal to process, and can adopt titanium sheet.Because slide plate 3 is very thin, lighter weight, therefore only needs less energy that it can be driven to move.During concrete enforcement, the motion of slide plate 3 is driven by safety control, namely adopts safety control it laterally to be moved away, and safety control is that employing is existing commercially available, and it does not comprise within the scope of the present invention.
Technique scheme is one embodiment of the present invention, for those skilled in the art, on the basis that the invention discloses application process and principle, be easy to make various types of improvement or distortion, and the method be not limited only to described by the above-mentioned detailed description of the invention of the present invention, therefore previously described mode is just preferred, and does not have restrictive meaning.
