Specific embodiment
As shown in figure 1, a kind of low impact high-mechanic firer's release screw bolt, by nut 1, pad 2, inner core 3, cellular components 4,
Shear pin 5, slide bar 6, voussoir 7, outer tube 8, piston 9, O-shaped rubber ring 10, medicine box 11, grate 12, aluminium packing ring 13, medicine shell 14,
Igniter 15 constitutes.3 one end of inner core is cylinder, through cellular components 4, the chorista bottom mounted externally of cellular components 4, inner core
3 other ends are cylindrical shape, in outer tube 8；Inside 3 cylinder end of inner core, one end is by radially inserting for slide bar 6
Shear pin 5 is fixedly connected with 3 side wall of inner core；Voussoir 7 through 3 side wall insertion 8 inwall of outer tube of inner core, positioned at slide bar 6 and outer tube 8 it
Between, for outer tube 8 and inner core 3 are connected；In outer tube 8, medicine shell 14 is not connected with inner core 3 piston 9 installed in outer tube 8
One end, installs shelves medicine plate 12 in the port being connected with outer tube 8, in medicine shell 14, medicine shell 14 installed by igniter 15 to medicine box 11
On, for gunpowder in the medicine box 11 that ignites；Outer tube 8 is mounted externally by chorista.
Nut 1, pad 2 and inner core 3 are connected with chorista, and wherein 3 material of inner core is titanium alloy material, effectively reduce inner core
To by the shock of chorista during 3 separation, so as to reduce impact, its tensile strength is close to stainless steel material, therefore bearing capacity
Unaffected.
Cellular components 4 are to select suitable aluminium foil honeycomb, the estimation side of aluminium foil honeycomb energy absorption by calculating with test
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.Need, by estimating release screw bolt, the energy that honeycomb absorbs, and by designing suitable cell dimensions, so that it may calculate honeybee
The compressive strength of nest, by honeycomb compressive strength from suitable honeycomb, the i.e. thickness of honeycomb aluminium foil and the size of honeycomb, pastes
In the bottom of chorista, both sides are stained with pad, it is ensured that inner core 3 clashes into the uniformity of cellular components 4.Cellular components 4 pass through precompressed
Honeycomb intensity is destroyed, gentle section is compressed using honeycomb and enters row buffering, so as to reduce impact.
As shown in Fig. 2 outer tube 8 by screw thread be connected by chorista, be connected by voussoir 7 between outer tube 8 and inner core 3,
7 material of voussoir is bearing steel, using 4 voussoirs 7, contacts for face, it is ensured that release screw bolt between voussoir 7 and inner core 3, outer tube 8
High-mechanic performance, voussoir 7 are bulk, are uniformly distributed along 3 circumference of inner core, and the one side that voussoir 7 is contacted with slide bar 6 is for adapting to slide bar 6
The circular arc of surface radian.The end face edge that voussoir 7 is contacted with inner core 3 has arc-shaped convex structure, for 8 points of inner core 3, outer tube
From after voussoir 7 is stuck in inner core 3, it is ensured that do not form fifth wheel.
As shown in figure 3, slide bar 6 is coordinated for hole axle with inner core 3, voussoir 7, slide bar 6 is fixed with inner core 3 by shear pin 5, is used
In the rigging position for ensureing 4 voussoirs 7, slide bar 6 is the integral structure that two sections of different cylinders of diameter constitute, and holds greatly end face
There are the thick annular thin-walled bulge-structure of 0.5mm, small end end face and 9 end thereof contacts of piston in edge.When slide bar 6 clashes into inner core 3, thin
Wall bulging deformation, slide bar 6 is fixed on inner core 3, it is ensured that after inner core 3 is separated with outer tube 8, and slide bar 5 will not form fifth wheel, right
3 shear pin hole position of inner core is closed up, it is ensured that shear pin 5 will not be skidded off.
Piston 9 is that hole axle coordinates with outer tube 8,2 O shape rubber seal 10 of installation, before O shape rubber seal 10 be used for
Shock of the damper piston 9 to outer tube 8, after O shape rubber seal 10 be used for seal, prevent powder gas reveal, inside outer tube 8
Step is provided with, is prevented piston 9 from flying out and causes gas leakage and fifth wheel.
Medicine box 11 is the celluloid medicine box containing double grains -17, impacts according to interior ballistic calculation and Firing test test
Method determines the explosive payload of double grains -17, on the premise of reliable unblock is ensured, reduces explosive payload so as to reduce impact.
Aluminium packing ring 13 is pure aluminum material, for the sealing between medicine shell 14 and outer tube 8.
Grate 12 is connected with medicine shell 14 by screw thread, opens 2 hole of Φ on grate 12, for the throttling of powder gas, from
And reduce the impact of powder gas.
Igniter 15 adopts two, is mutually redundant, it is ensured that the reliability of unblock.
The operation principle of the present invention is：Carried by 8 screw thread of outer tube, 3 screw thread of inner core and 1 pad 2 of nut before work.
During 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 produces high
Warm high-pressure gas, by the throttling action of throttle orifice on grate 12, promote piston 9, slide bar 6 to cut off shear pin 5, continue forward
Motion, voussoir 7 are released, and the constraint between inner core 3 and outer tube 8 is released from, and combustion gas promotes piston 9, slide bar 6 to continue to transport forward
Dynamic, inner core 3 is clashed into, above boss deformation is limited for slide bar 6, and slide bar 6, voussoir 7 and inner core 3 travel forward together and realize unblock work(
Can, and clash into cellular components 4 together, cellular components 4 are plastically deformed energy-absorbing and realize low impact property, and piston 9 is limited by 8 step of outer tube
Position, realizes sealing property.Now, chorista is separated from by chorista.
Bearing function is realized by the cooperation of inner core 3, voussoir 7 and outer tube 8, using 4 voussoirs 7, a size of 6mm of voussoir 7
× 5.3mm × 5.45mm, material are bearing steel, 3 material titanium alloy of inner core, and overall diameter is Φ 20mm, and interior diameter is Φ 12mm, outward
8 materials of cylinder are stainless steel, and inner diameter size is Φ 20mm, and overall diameter is Φ 30mm, realizes release screw bolt high-mechanic performance, passes through
Verification experimental verification, product are destroyed more than appearance in the case of 70kN nothing injurious deformation under 40kN axial load.
By opening the throttle orifice of a diameter of Φ 1mm～2.5mm on grate 12, piston 9 above increases O-shaped rubber ring 10 and delays
The shock rushed between piston 9 and outer tube 8,3 material selection titanium alloy of inner core, it is ensured that in the case of intensity, compared with steel, mitigate
The weight of half, is clashed into by aluminum alloy honeycomb component buffers inner core, and three aspects realize the low impact characteristics of release screw bolt.
Unspecified part of the present invention belongs to technology as well known to those skilled in the art.
