Abstract
The invention discloses a kind of primacord propagation of explosion energy amplifying device, the propagation of explosion energy of Confined detonating fuse can be amplified, improve Confined detonating fuse and ignite subordinate compared with the reliability of insensitiveness firer unit, can be applicable on weapons and ammunitions Explosive sequence under narrow and small environment and industrial explosive material.This device primarily of single core Confined detonating fuse 1, expand quick-fried casing 2 and booster explosive 3 forms, operation principle is after Confined detonating fuse is ignited, blast energy is given the booster explosive in the quick-fried casing of expansion and is ignited, again by booster explosive by its blast energy to subordinate firer unit, realize transmission and the amplification of explosion energy.
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 Explosive sequence and industrial explosive material.
Background technology
Be widely used in various sophisticated weapon system and industrial explosive material as the primacord transmitting explosion energy, but comparatively high explosive is low for the explosion velocity of primacord own, medicine core is thin, output energy comparison is limited, direct initiation can not be used for compared with the powder column of insensitiveness or warhead main charge, a propagation of explosion energy amplifying device must be had to improve the output energy of primacord.Research in this regard is both at home and abroad more active, the quick-fried device of similar expansion or transmission detonation joint kind more, but complex structure, volume are comparatively large 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: the propagation of explosion energy amplifying Confined detonating fuse, improve Confined detonating fuse and ignite the reliability of subordinate compared with 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, expands quick-fried casing 2 and booster explosive 3 forms;
Described Confined detonating fuse 1 is made up 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;
Described expansion quick-fried casing 2 open at both ends, there is a boss centre, intermediate lands 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 inwall of expansion and boss upper surface, medicine core passes from boss centre bore;
Described booster explosive 3 is fitted in and expands in powder charge cavity volume that quick-fried casing 2 other end and medicine core formed.
Operation principle: after Confined detonating fuse 1 is ignited, blast energy is given the booster explosive 3 that expands in quick-fried casing 2 and is ignited, then by booster explosive 3 by its blast energy to subordinate firer 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 that structure is simple, volume is little, detonation propagation reliability of nonel tube high, can be applicable on weapons and ammunitions Explosive sequence under narrow and small environment and industrial explosive material.

Detailed description of the invention
Now the invention will be further described with specific embodiment by reference to the accompanying drawings:
Consult Fig. 1, Fig. 2, single core Confined detonating fuse XBS2-1(A) external diameter φ 5.0mm, peel off one end clad, the medicine core length exposing external diameter φ 1.0mm is 6.0mm.Primacord insertion is expanded quick-fried casing inwall bore φ 5.0mm one end and is inserted into the end, and primacord medicine core passes the hole of the quick-fried casing boss φ 1.0mm of expansion and stretches out boss lower surface 3.0mm, and primacord clad is close to the quick-fried casing inwall of expansion and boss upper surface.HNS-II explosive is press-fited, degree of packing 1.50g/cm in the powder charge cavity volume that the quick-fried casing inwall bore φ 4.0mm one end of expansion and primacord medicine core are formed
3~ 1.70g/cm
3, should be about 150mg according to powder charge chamber volume calculations explosive payload, make primacord medicine core imbed HNS-II powder column 3mm, equating exposed HNS-II grain surface is also coated with the military lacquer that concentration is 40%.
Consult Fig. 3, Fig. 4, single core Confined detonating fuse is made up of clad and medicine core, clad external diameter φ 5.0mm, 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 inner wall bore φ 4.0mm, intermediate lands thickness 3.0mm, the through hole of a φ 1.0mm is made a call to and coaxial with the hole of φ 5.0mm, φ 4.0mm in boss center.
