Description
Technical field
The invention belongs to firearms field, be specifically related to the piston of a kind of shotgun gas directing system and prevent shotgun
The method of gas directing system gum deposit.
Background technology
No. 12 bore Semi-automatic shotguns use plastic housing shotgun shell, as it is shown in figure 1, this bullet bullet is by plastics
Bullet torr 1 and steel ball 2 form, and because its gun pressure is relatively low, need bigger or more gas port could meet certainly
Motivation circulating energy, general gas port aperture is at Φ 2.5～Φ 6 (porous takes little, and single hole takes greatly).Such as figure
Shown in 1, because of gun pressure effect during plastics bullet torr 1 gun barrel inducing QI aperture 4 excessively, form bullet torr protuberance 3, this
Place is easily sheared by gun barrel inducing QI aperture 4, and the plastic flakes 12 dropped arrives regulation by gun barrel inducing QI aperture 4
Passage between device inducing QI aperture 5 also enters original volume 14, in the process, because of lasting High Temperature High Pressure
The effect of powder gases makes plastic flakes melt, and the plastics of fusing can be deposited in original volume or enter
Gap between piston and actuator, actuator and gas block, after lifting fire or cooling down firearms, plastics coagulate
Gu, form so-called " gum deposit "." gum deposit " causes original volume to reduce, piston movement is dumb or inducing QI
Hole path is occupied, and causes automat work capacity not enough, and even ejection breaks down.When launching relatively
After many quantity bullet in gas regulating system a large amount of " gum deposit ", lift fire or cool down firearms post regulator 7
Rotate dumb, be not easy to regulation.Russia's VEPR shotgun is provided a kind of being increased by piston and holds glue
Groove improves gas directing system and enters the scheme of glue, but the problem failing thoroughly to solve gum deposit.
Summary of the invention
Enter glue can not effectively discharge to solve the gas directing system of above-mentioned shotgun, affect shotgun serviceability
Problem, the invention provides the piston of a kind of shotgun gas directing system and prevents shotgun gas directing system gum deposit
Method.
The present invention is achieved through the following technical solutions:
A kind of piston of shotgun gas directing system, the outer peripheral face of described piston be provided with a chip removal annular groove and
Some glue grooves, described each glue groove is uniformly located at the front portion of piston, and piston is run through in the front end of each glue groove,
Described chip removal annular groove is positioned at the rear of each glue groove, and chip removal annular groove, along the circumferentially extending circle of piston, respectively holds glue
The rear end of groove all connects with chip removal annular groove.
In order to change the original volume of actuator, it is preferable that the front end face of described piston is provided with an edge
Piston axially extended original volume regulation head, the radius of original volume regulation head is less than each glue groove bottom land
Distance between piston axis.
On the one hand, original volume can be regulated by changing original volume regulation header structure parameter so that it is more
Rationally, thus optimize gas directing system energy；On the other hand, original volume regulation head is possible to prevent plastics broken
Sheet collides the front end face of piston in motor process, makes to be looped around original volume regulation head in motor process
Surrounding, it is easier to entering in glue groove, chip removal effect is more preferable.
In order to improve original volume regulation head to air-flow, the guide effect of plastic flakes, it is preferable that described
Original volume regulation head front end is the guide head of taper.
Suck back to prevent plastic flakes to be reversed in gas directing system original volume, it is preferable that described each appearance
The longitudinal direction of glue groove is all the most staggered with the axial space of piston, angulation α.
On the one hand, glue groove and piston axis are crisscross arranged and can increase the area of glue groove front end oral area,
Making plastic flakes be easier to enter in glue groove, chip removal effect is more preferable；On the other hand, plastic flakes passes through
After glue groove, the cell wall with chip removal annular groove interacts, and changes the position of plastic flakes, makes plastic flakes
Length direction is parallel to the bearing of trend of chip removal annular groove, it is easier to moves in chip removal annular groove and then discharges,
Plastic flakes is prevented to be blocked in chip removal annular groove.
In order to improve the chip removal effect of glue groove, it is preferable that described glue groove on the outer peripheral face of piston in
Spiral extension.
In order to increase the piston obturation effect to air-flow, it is preferable that the outer peripheral face of described piston be provided with to
A few annular groove of holding one's breath, described in annular groove of holding one's breath be positioned at the rear of chip removal annular groove, annular groove of respectively holding one's breath is along piston week
To extending a circle.Piston is at least two sections along longitudinal subdivision by annular groove of holding one's breath, and each end all can be with inducing QI banding
Contiguity is touched, and sealing property is more preferable.Preferably, the quantity of annular groove of holding one's breath described in is two.
Preferably, described glue groove connect with chip removal annular groove after passage, along airflow direction cross-sectional area not
Become or be gradually increased." threshold " will not be shunk or occur, enable plastic flakes to discharge smoothly.
A kind of method preventing shotgun gas directing system gum deposit by shotgun piston, the plastics bullet torr of shotgun shell is led to
Forming bullet torr protuberance because of gun pressure effect when crossing gun barrel inducing QI aperture, bullet torr protuberance is by gun barrel inducing QI aperture
Shearing, the plastic flakes dropped passes through gun barrel inducing QI aperture to actuator inducing QI aperture along with the air-flow derived
Between passage enter in the original volume of actuator, after air-flow that the piston in gas block is exported promotes
Sitting, until chip removal annular groove connects with gas block steam vent, form current path, plastic flakes is along with derivation
Air-flow pass sequentially through the glue groove on shotgun piston and chip removal annular groove is discharged by gas block steam vent.
Beneficial effects of the present invention:
Arranging glue groove and chip removal annular groove on shotgun piston, both connections are as gas directing system residual air and broken
The passage that sheet is discharged, and realize gum deposit discharge with other parts of gas directing system composition binder removal passage.Hold
The passage that glue groove and chip removal annular groove are discharged as gas directing system residual air and fragment, chip removal annular groove is set to annular,
When may insure that piston variation of axial position, residual air discharge concordance is good, does not affect gunlock energy, more can guarantee that work
Plug system capacity when residual air is discharged is more stable.Gum deposit in gas regulating system can be discharged by the present invention,
The regulation comfortableness of piston movement motility and gas regulator can be effectively ensured, it is ensured that the energy of automat
Stable, the most substantially shorten and clean the wiping time.
