3 other ends are cylindrical shape, are mounted in outer cylinder 8；Slide bar 6 is mounted on inside 3 cylinder end of inner cylinder, and one end, which passes through, to be radially inserted into
Shear pin 5 is fixedly connected with 3 side wall of inner cylinder；Voussoir 7 passes through 3 side wall of inner cylinder and is inserted into 8 inner wall of outer cylinder, be located at slide bar 6 and outer cylinder 8 it
Between, for outer cylinder 8 and inner cylinder 3 to be connected；Piston 9 is mounted in outer cylinder 8, and medicine shell 14 is mounted on what outer cylinder 8 was not connect with inner cylinder 3
One end installs shelves medicine plate 12 in the port connecting with outer cylinder 8, and medicine box 11 is mounted in medicine shell 14, and igniter 15 installs medicine shell 14
On, for gunpowder in the medicine box 11 that ignites；Outer cylinder 8 is mounted on outside by chorista.
Nut 1, gasket 2 and inner cylinder 3 are connect with chorista, and wherein 3 material of inner cylinder is titanium alloy material, and inner cylinder is effectively reduced
To by the shock of chorista when 3 separation, to reduce impact, tensile strength and stainless steel material are close, therefore bearing capacity
It is unaffected.
Cellular components 4 are to select suitable aluminium foil honeycomb with test by calculating, and aluminium foil honeycomb absorbs the estimation side of energy
Method: in W=PS Δ L formula: P: the compressive strength of cellular material；S: the compressing area of the material of cellular material；△ L: the pressure of cellular material
Contracting length.The energy for needing honeycomb to absorb by estimating release screw bolt, and by designing suitable cell dimensions, so that it may calculate bee
The compressive strength of nest is selected suitable honeycomb, the i.e. thickness of honeycomb aluminium foil and cellular size by honeycomb compressive strength, is pasted
In the bottom of chorista, both sides are stained with gasket, guarantee that inner cylinder 3 hits the uniformity of cellular components 4.Cellular components 4 pass through precompressed
Honeycomb intensity is destroyed, gentle section is compressed using honeycomb and is buffered, to reduce impact.
As shown in Fig. 2, outer cylinder 8 is connect by screw thread with by chorista, connected between outer cylinder 8 and inner cylinder 3 by voussoir 7,
7 material of voussoir is bearing steel, using 4 voussoirs 7, is face contact between voussoir 7 and inner cylinder 3, outer cylinder 8, guarantees release screw bolt
High-mechanic performance, voussoir 7 are bulk, are circumferentially uniformly distributed along inner cylinder 3, the one side that voussoir 7 is contacted with slide bar 6 is to adapt to slide bar 6
Surface radian it is arc-shaped.The end face edge that voussoir 7 is contacted with inner cylinder 3 has arc-shaped convex structure, divides for inner cylinder 3, outer cylinder 8
Voussoir 7 is stuck in inner cylinder 3 from after, guarantee does not form fifth wheel.
As shown in figure 3, slide bar 6 and inner cylinder 3, voussoir 7 are hole axle cooperation, slide bar 6 is fixed by shear pin 5 and inner cylinder 3, uses
In the rigging position for guaranteeing 4 voussoirs 7, slide bar 6 is the integral structure of the different cylindrical body composition of two sections of diameters, big end end face
There are the circular ring shape thin-walled bulge-structure of 0.5mm thickness, small end end face and 9 end thereof contacts of piston in edge.It is thin when the shock inner cylinder 3 of slide bar 6
Slide bar 6 is fixed on inner cylinder 3 by wall bulging deformation, and after guaranteeing that inner cylinder 3 is separated with outer cylinder 8, slide bar 5 not will form fifth wheel, right
3 shear pin hole location of inner cylinder closes up, and guarantees that shear pin 5 will not skid off.
Piston 9 and outer cylinder 8 are that hole axle cooperates, and install 2 O shape rubber seal 10, before O shape rubber seal 10 be used for
Shock of the damper piston 9 to outer cylinder 8, behind O shape rubber seal 10 for sealing, prevent powder gas from revealing, inside outer cylinder 8
Equipped with step, prevents piston 9 from flying out and cause gas leakage and fifth wheel.
Medicine box 11 is the celluloid medicine box containing double grains -17, is impacted according to interior ballistic calculation and Firing test test
Method determines the explosive payload of double grains -17, under the premise of guaranteeing reliable unlock, reduces explosive payload to reduce impact.
Aluminium washer 13 is pure aluminum material, for the sealing between medicine shell 14 and outer cylinder 8.
Grate 12 is connect by screw thread with medicine shell 14, and 2 hole Φ is opened on grate 12, for the throttling of powder gas, from
And reduce the impact of powder gas.
Igniter 15 uses two, is mutually redundant, and guarantees the reliability of unlock.
The working principle of the invention is: being carried before work by 8 screw thread of outer cylinder, 3 screw thread of inner cylinder and 1 gasket 2 of nut.
When work, igniter 15 is connected to electric signal ignition, and igniter 15 works, the double grains -17 in medicine box 11 are lighted, and burning generates high
Warm high-pressure gas is pushed piston 9, slide bar 6 to cut shear pin 5, is continued forward by the throttling action of throttle orifice on grate 12
Movement, voussoir 7 are released, and the constraint between inner cylinder 3 and outer cylinder 8 is released from, and combustion gas pushes piston 9, the continuation of slide bar 6 to transport forward
It is dynamic, inner cylinder 3 is hit, the deformation of 6 front boss of slide bar is limited, and slide bar 6, voussoir 7 and inner cylinder 3 travel forward together realizes unlock function
Can, and cellular components 4 are hit together, 4 plastic deformation and energy-absorbing of cellular components realizes low impact property, and piston 9 is limited by 8 step of outer cylinder
Sealing performance is realized in position.At this point, chorista is separated from by chorista.
Bearing function is realized by the cooperation of inner cylinder 3, voussoir 7 and outer cylinder 8, and using 4 voussoirs 7, voussoir 7 is having a size of 6mm
× 5.3mm × 5.45mm, material are bearing steel, and 3 material titanium alloy of inner cylinder, overall diameter is Φ 20mm, and interior diameter is Φ 12mm, outside
8 materials of cylinder are stainless steel, and inner diameter size is Φ 20mm, and overall diameter is Φ 30mm, realize release screw bolt high-mechanic performance, pass through
Verification experimental verification, product under 40kN axial load without injurious deformation, more than being destroyed in the case of 70kN.
It is slow to increase O-shaped rubber ring 10 by opening the throttle orifice that diameter is Φ 1mm~2.5mm on grate 12, before piston 9
Rush the shock between piston 9 and outer cylinder 8,3 material selection titanium alloy of inner cylinder in the case where proof strength, compared with steel, mitigates
The weight of half is hit by aluminum alloy honeycomb component buffers inner cylinder, and three aspects realize the low impact characteristics of release screw bolt.
Unspecified part of the present invention belongs to technology well known to those skilled in the art.
