Description
Technical field
Utility model is related to a kind of body, and in particular to a kind of body suitable for pressure encapsulation.
Background technology
Smoke shell is made up of body, screening smoke, fuse and igniting powder charge etc., and the Structure ＆ Intensity of body are to influence smoke screen
Play a key factor of smoke screen effect.
According to technology operational requirements, the structure design of smoke shell primarily focuses on the quick of screening smoke, large area release, changed
The airborne period and raising assembling accuracy of kind smoke screen, to obtain maximum interference effect.To make smoke shell reach due dry
Effect is disturbed, using the cylindrical type body structure of the weak barrel of strong end plate, the space that barrel and end plate are formed is used for loading decentralized medium
Carbon fiber, and require in the case of less booster amount, body is easy to disintegrate, and the radial direction throwing beneficial to screening smoke dissipates, and most
The flat smoke cloud with certain dead area can be formed eventually.Body structure intensity and booster power mutually restrict,
And smoke cloud shape after explosive dispersion can be directly affected, so needing to optimize the structure and intensity of body.
Loading density is an important parameter of body structure design, determines the effective loadings and body of destructor
Gross mass, also it is related to the size of unit volume load dead area.Carbon fiber apparent density is small, and is pressed easily bounce-back, it is desirable to
Certain strict density can be reached in body during filling carbon fiber to improve skill war ability.

To load carbon fiber.
The described body for being applied to pressure encapsulation includes：Body capping, increased pressure board, shell of the projectile body, core pipe and core pipe spiral shell
It is female.
External screw thread is provided with the shell of the projectile body bottom lock, open top and the outer circumference surface of opening；The bullet
Body capping is coordinated by the external screw thread at the top of the internal thread and shell of the projectile body on its inner peripheral surface to be arranged at the top of shell of the projectile body；
The increased pressure board is used to transmit pressure to carbon fiber during carbon fiber is loaded into shell of the projectile body；The core pipe
On be provided with the shaft shoulder；The shell of the projectile body is built-in complete carbon fiber after, the bottom of the core pipe and the inner bottom surface of shell of the projectile body connect
Touch, the increased pressure board is located between the shaft shoulder of core pipe and the inner bottom surface of body capping；The top of the core pipe covers through body
Perforate after couple with the core pipe nut thread.
At screw thread cooperation the thickness of the shell of the projectile body be at undressed screw thread on the basis of shell of the projectile body thickness at least
Increase the height of a screw thread thread.
On the shell of the projectile body externally threaded length be seven times of teeth away from.
What the external thread structure and size uniformity being machined with the shell of the projectile body bottom cylindrical side face at the top of with it caused
External screw thread.
Beneficial effect：
(1) body capping uses internal thread, and body shell uses external screw thread, and this structure can make smoke shell projectile explosive

Embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
The present embodiment provides a kind of body suitable for pressure encapsulation, and the body of this kind of structure type can not only make smoke screen
First axial tension during bullet projectile explosive, then radially explodes, advantageously forms flat smoke cloud, reach elimination smoke screen
Bullet " mushroom " smoke, mists and clouds and the purpose for improving dead area；And suitable for loading carbon fibre using body pressure packaging system
Dimension.
As shown in figure 1, the body includes：Body capping 8, increased pressure board 9, shell of the projectile body 11 and core pipe 12；Wherein body shell
External screw thread is provided with the bottom lock of body 11, open top and the outer circumference surface of opening；In order to ensure shell of the projectile body 11 quick-fried
The symmetry of casing rigidity and mechanical property when fried, prevents the bottom of shell of the projectile body 11 from turning into dangerouse cross-section in explosion time and breaking in advance
Split, influence explode cloud cluster expected from shape, on the outer circumference surface of the bottom of shell of the projectile body 11 increase wall thickness to screw top phase
Same external diameter, and design and top identical external thread structure, i.e., have on the outer circumference surface of the top and bottom of shell of the projectile body 11
Symmetrical external screw thread in its height direction, the mechanical property similar to top is consequently formed, while is also convenient for the sleeve 10 that feeds
Work, avoid feed sleeve 10 damage.Body capping 8 passes through the internal thread on its inner peripheral surface and the top of shell of the projectile body 11
External screw thread coordinate and be arranged on the top of shell of the projectile body 11.Body capping is contrasted using external screw thread, body shell using internal thread
(thread connection mistake can occur connection form when pressure moment increases in body during smoke shell projectile explosive for this structure
The situation of effect, the radial direction for being unfavorable for carbon fiber throw the phenomenon for dissipating and eliminating smoke shell " mushroom " smoke, mists and clouds)；In body capping uses
Screw thread, body shell can make first axial tension during smoke shell projectile explosive, Ran Houjing using externally threaded connection form
To blast, flat smoke cloud is advantageously formed, reaches the mesh for eliminating smoke shell " mushroom " smoke, mists and clouds and improving dead area
's.
The internal diameter and internal height of shell of the projectile body 11 are determined by the screening smoke, fuse and powder charge etc. of lighting a fire loaded.Body
The structure of housing 11 is as shown in Fig. 2 shell of the projectile body 11 and the material of body capping 8 are duralumin, hard alumin ium alloy, in order to not reduce body
The mechanical property of housing at the thread connection of housing 11, ensure the uniformity of the intensity of shell of the projectile body 11, to the body at screw thread cooperation
Housing 11 thickeies, and thickness at least increases the height of a screw thread thread, then carries out rounding.
Because even if thread connection is manufactured and assembled all very accurately, its stress respectively enclosed in screw thread teeth is also to differ
's.It is demonstrated experimentally that 1/3rd load concentration is there are about on first lap, the later screw thread teeth hardly stand under load of the 8th circle
Lotus, thus set screw thread working depth h as seven times of teeth away from, it is contemplated that be threaded into chamfer during processing for convenience of Screw assembly
Reduce the working depth of screw thread, slightly larger than seven times teeth of setting screw thread working depth h away from.
When may indicate that shell of the projectile body 11 will rupture by theoretical calculation, shell of the projectile body 11 is in axial direction torn at first
Split, meet first axial tension in smoke shell blast process, then radially explode, reach and eliminate wanting for smoke shell " mushroom " smoke, mists and clouds
Ask, while the intensity of body 8 screw threads of capping meets design requirement.
