Abstract
A bullet has a cartridge case to be discarded, which brings a lot of troubles. Now the invention processes the warhead part and the body part into a whole. Wherein, a primer cup is produced by solid sropellant wrapping gunpowder through cementation and is arranged at the step in the rear port of the body with pressure welding or cementation. When launching, the body is launched with the warhead, so there is nothing in the chamber so as to achieve that there is no cartridge case after launching. In the meantime, the invention causes the quality of the body to become part of the quality of the warhead, thus the bullet can launch maximum quality under the same caliber. That is, the invention can increase combat action of the warhead.
Description
Technical field
The present invention relates to a kind of weaponry, especially bullet.
Background technology
Bullet generally is made up of bullet, body, propellant powder and primer cup, and the gun propellant combustion of percussion back produces gases at high pressure bullet is penetrated, and empty body and empty primer cup are then dished out outside the bore as shell case.
Bullet has the shell case that need abandon, with regard to related several problems: the one, in order to guarantee bullet enough lethality is arranged, suitably big warhead mass just must be arranged, this just makes bullet volume and whole bullet volume increase, firearms also must increase thereupon, the consumption goods and materials are many, and logistics freight volume and soldier carry weight all to be increased; The 2nd, the recycling of shell case also has many work to do.
The external report that No-case bullet was once arranged, generally be that body is manufactured with propellant powder, percussion back body burns and does not have shell, but the bullet of this No-case bullet and the bond strength of body are difficult problems, body also had the danger of spontaneous combustion when the bore temperature was high, so not seeing recent decades has this class No-case bullet to equip.
Domestic have " a kind of No-case bullet " (number of patent application: 96210050.1) patent application, it is " the cartridge case part of having cancelled conventional bullet " and the no shell that forms, in narrow and small bullet inner space, filled propellant powder, also do not design the structure that extracts, such No-case bullet also is difficult to practicability.
Summary of the invention
After solving existing bullet shooting shell and related problem thereof are arranged, the invention provides a kind of bullet, can solve with this bullet has shell and related problem thereof after having bullet shooting now.
The present invention solves the technical scheme that its problem takes:
The bullet position and the body position of bullet are processed as an overall structure, and hard solid (caliber hour can with it and bullet merging) is equipped with in the front portion in bullet and the body, and body is a cavity, and a step is arranged in the body rear port; The bullet external diameter is more smaller than gun barrel internal diameter with the body external diameter; On the periphery of body sealing ring is arranged, the big bullet body diameter of sealing ring external diameter; Primer cup is made through gluing parcel percussion charge by solid gun propellant, crimping or be bonded in step place in the body rear port; Outer surface height after primer cup is installed is a little less than the body rear end face.
Propellant powder is contained in the body cavity.Ditch extracts at body periphery rear portion.
The structure and the action principle of bullet of the present invention are:
The bullet position become with the body position as a whole after, during emission, body will penetrate with bullet, no cartridge case was abandoned after this had just accomplished shooting, can make simultaneously the quality of body become the part of warhead mass, like this, under the identical situation of caliber, bullet of the present invention can penetrate the quality maximum of part, and the strike effect of bullet is increased.
Bullet maximum outside diameter and body external diameter be all than in the little 0.05mm of gun barrel internal diameter, so that bullet, body can be advisable near frictionless motion in gun barrel.Sealing ring one on the body periphery is to seal bore with the maintenance gun pressure, the 2nd, and bullet is produced under the rifling effect rotatablely move to keep the stability of bullet firing direction.
Primer cup is made through gluing parcel percussion charge by solid gun propellant.The step internal diameter matches in the external diameter of primer cup and the body rear port, makes closely crimping or be bonded in step place in the body rear port of primer cup.About the low 0.2mm of the outer surface aspect ratio body rear end face after primer cup is installed, to reduce the possibility that the fire in a stove before fuel is added is bumped by mistake.
During percussion, the blast of percussion charge in the primer cup ignite propellant powder in the primer cup and the propellant powder in the body, the gases at high pressure of generation with regard to vacancy, can then have been launched next bullet in the bore after bullet bullet and body are extruded bore.
If bullet advances and does not launch behind the thorax and need extract the time, grabbing on the gunlock colluded and caught the ditch that extracts of bullet rear end to withdraw from bullet outside the thorax.
The beneficial effect of bullet of the present invention is, shell and related problem thereof arranged after having solved existing bullet shooting, can obtain satisfied result of use.The bullet structure is uncomplicated, manufactures not difficult.
Description of drawings
Accompanying drawing is the structural representation of bullet of the present invention.
Among the figure: 1. bullet 2. hard solids 3. bodies; 4. sealing ring; 5. primer cup; 6. percussion charge; 7. step 8. propellant powder; 9. ditch extracts.
Specific embodiments
Structure and effect situation below in conjunction with description of drawings bullet of the present invention.
As shown in the figure, it is interior anterior with body (3) that hard solid (2) is arranged on bullet (1), body (3) is an overall structure with bullet (1), on body (3) periphery sealing ring (4) is arranged, solid gun propellant is wrapped in percussion charge (6) and constitutes primer cup (5), and primer cup (5) is bonded in the interior step (7) of body rear port and locates.
Propellant powder (8) is contained in the cavity of body (3).Ditch (9) extracts in body (3) periphery rear end.
After the gunlock firing pin hits primer cup (5), percussion charge (6) in the primer cup (5) catches fire, the ignite solid gun propellant of primer cup (5) and the propellant powder (8) in the body (3) produces gases at high pressure, promoting bullet (1) and body (3) moves along gun barrel, play the effect of sealing bore inner high voltage gas in the rifling of sealing ring (4) the embedding gun barrel on body (3) periphery, bullet (1) and body (3) are rotated.
After bullet (1) and body (3) were launched muzzle, no cartridge case can be thrown in the bore.Propellant powder in the bullet of the present invention (8) and primer cup (5) are also with completing combustion, and vacancy in the bore can then have been launched next bullet.
If bullet of the present invention advances and does not launch behind the thorax and need extract the time, can utilize grabbing on the gunlock to collude and catch the ditch that extracts (9) at bullet rear portion to withdraw from bullet outside the thorax.
