Abstract
The invention discloses an explosion propagation energy amplification device of a detonating cord. According to the explosion propagation energy amplification device of the detonating cord, the propagation explosion energy of the restrictive detonating cord can be amplified, the reliability for the restrictive detonating cord to ignite an subordinate insensitiveness fiber unit is improved, and the explosion propagation energy amplification device can be applied to arms and ammunition explosion propagation sequences under the narrow environment and industrial explosive materials. The explosion propagation energy amplification device of the detonating cord is mainly composed of the single-core restrictive detonating cord 1, an explosion amplification head shell 2 and a booster explosive 3. According to the operating principle, after the restrictive detonating cord is ignited, the explosion energy is transferred to the booster explosive in the explosion amplification head shell to ignite the booster explosive, the booster explosive transfers the explosion energy to the subordinate insensitiveness fiber unit, and then the explosion energy is transferred and amplified.
Description
Technical field
The present invention relates to a kind of primacord propagation of explosion energy amplifying device, this device can amplify the propagation of explosion energy of Confined detonating fuse, improve Confined detonating fuse and ignite subordinate compared with the reliability of insensitiveness firer unit, can be applicable on weapons and ammunitions propagation of explosion sequence and industrial explosive material.
Background technology
As the primacord that transmits explosion energy, in various sophisticated weapon systems and industrial explosive material, be widely used, but the explosion velocity of primacord own is low compared with high explosive, medicine core is thin, output energy comparison is limited, can not be used for direct initiation compared with the powder column of insensitiveness or warhead main charge, must have a propagation of explosion energy amplifying device to improve the output energy of primacord.Research in this regard is both at home and abroad more active, similarly expands quick-fried device or transmission detonation joint kind is more, but complex structure, volume are larger mostly, are unfavorable for production and processing and use under the environment of limited space.
Summary of the invention
The object of the invention is: amplify the propagation of explosion energy of Confined detonating fuse, improve Confined detonating fuse and ignite subordinate compared with the reliability of insensitiveness firer unit.
Technical scheme of the present invention is: a kind of primacord propagation of explosion energy amplifying device, by single core Confined detonating fuse 1, expand quick-fried casing 2 and booster explosive 3 forms;
Described Confined detonating fuse 1 is comprised of Confined detonating fuse clad 4 and Confined detonating fuse medicine core 5, peels off the clad of one end, exposes one section of medicine core;
Quick-fried casing 2 open at both ends of described expansion, there is a boss centre, middle boss center is porose, one section of medicine core that Confined detonating fuse 1 exposes and boss inwall matched in clearance, medicine core passes from boss centre bore, and primacord clad 4 is close to the quick-fried casing 2 one end inwalls of expansion and boss upper surface, and medicine core passes from boss centre bore;
Described booster explosive 3 is fitted in the powder charge cavity volume that expands quick-fried casing 2 other ends and the formation of medicine core.
Operation principle: after Confined detonating fuse 1 is ignited, blast energy is given and expanded the booster explosive 3 in quick-fried casing 2 and ignited, then by booster explosive 3 by its blast energy to the firer of subordinate unit, realize transmission and the amplification of explosion energy.
The invention has the beneficial effects as follows: the primacord propagation of explosion energy amplifying device that the present invention proposes, have simple in structure, volume is little, detonation propagation reliability of nonel tube high, can be applicable in the weapons and ammunitions propagation of explosion sequence and industrial explosive material under narrow and small environment.

3～1.70g/cm
3, according to powder charge chamber volume calculations explosive payload, should be about 150mg, make primacord medicine core imbed HNS-II powder column 3mm, equating exposed HNS-II grain surface to be coated with concentration be 40% military lacquer.
Consult Fig. 3, Fig. 4, single core Confined detonating fuse is comprised of clad and medicine core, clad external diameter φ 5.0mm, and medicine core external diameter φ 1.0mm, peels off clad, exposes medicine core length 6.0mm.
Consult Fig. 5, Fig. 6, expand the part that quick-fried casing is a stainless steel, open at both ends, there is a boss centre.Expand quick-fried casing length 20.0mm, housing upper end inwall bore φ 5.0mm, lower end inwall bore φ 4.0mm, middle boss thickness 3.0mm, the through hole of a φ 1.0mm coaxial with the hole of φ 5.0mm, φ 4.0mm is made a call at boss center.
