Invention field
The present invention relates generally to small arms, particularly is used to control the action rate control system of action system of the small arms of gas-operated.
Background of invention
The action system that " gas-operated " small arms such as semi-automatic small arms usually utilize during the ammunition of a bullet is got angry the internal bore pressures of overflowing from the gun barrel of small arms and/or burning gases to drive small arms.Usually, the action system of small arms comprises on the rifle bolt device that is attached at small arms and the action sleeve device or the slideway that are communicated with it.During operation, when opening fire, burning gases are transferred to this action system from the gun barrel of small arms through a series of holes, and this series of apertures is mach circular hole in the gun barrel wall normally.The burning gases of this transfer force this action sleeve device to arrive the halt on border, a back backward usually, make that the bullet that is consumed is ejected; Striker is moved to a trigger ready position; And a new ammunition bullet is loaded onto in the magazine of small arms when this action system is closed.
The amount of the cumulative volume adjustments of gas of these gun barrel mesopores also thereby is regulated the energy total amount be sent to action system.But, there is a problem for the small arms that load, just, the ammunition amount of providing that differs widely (also i.e. the explosive payload of the heavy dose of gunpowder of opening fire in the small arms of shotgun, rifle and other type with respect to lighter target practice explosive payload) can be arranged in specific bore, make by gas volume control uniquely small arms action system energy and/or to move be unpractiaca.For example, require usually than producing from the explosive payload of the less energy of generation of the target practice explosive payload that is used for bullet than the remarkable bigger aperture of the explosive payload of macro-energy, so that provide the gas of enough volumes to drive action system.Therefore, common physical dimension with the hole in the small arms of gas-operated is created as to pack into and produces the explosive payload of least energy, also promptly have bigger hole, in a kind of test, utilize the compensation arrangement that joins in the action system to reduce when using generation, to be sent to the energy of action system than the ammunition of macro-energy.
Compensation arrangement generally includes spring-loaded pressure-reducing valve, this pressure-reducing valve was driven when a predetermined pressure that is provided by this spring was provided usually for operating energy in system or gas pressure, and this recuperation valve or pressure-reducing valve will be opened and the too much energy/gas of a part is gone by ease or discharges this moment.Though this type of bucking-out system can reduce to import energy (gas pressure), still there is marked difference in the energy that can be used to drive the action system of small arms.Usually utilize bolt velocities as the relative tolerance of guiding the energy total amount of action system into, bolt velocities is high more, and the energy of guiding action system into is just big more.
The bolt velocities that Fig. 1 produces high-energy and low-energy ammunition bullet substantially in a kind of traditional compensation semi-automatic shotgun of illustration relatively.As shown in fig. 1, in a kind of so traditional compensation small arms, there is marked change in the dissimilar ammunition for using in peak bolt speed and the action system terminal velocity.Usually, the bullet that produces the bullet of higher-energy such as heavy dose of ammunition has very high peak velocity as up to 400 inches of per seconds.This bolt velocities quite stable and can not weakening in whole stroke, up to rifle bolt move to thereafter abut and its further motion be stopped.The peak velocity that produces more low-energy bullet is so high unlike producing high-octane bullet usually, only is generally 300 inches of per seconds, and often keeps suitable stable in a long time.In other words, traditional bucking-out system is usually very near peak value, keeps suitable stable then at the whole stroke of small arms or in the cycle, bumps against the rear portion of recipient up to it, then stops suddenly and might cause damage.For the bullet that produces more low-energy bullet and higher-energy, the energy total amount of inserting is limited, but energy does not consume during whole stroke.
For the auto-manual system small arms, best design should be, no matter the type of ammunition bullet in the small arms can both provide consistent bolt velocities distribution map, and can have minimum terminal velocity complete guarantee stroke with enough energy operations.When opening fire, the timing of the various mutual mechanisms that the influence of speed that action system moves forms owing to the operation of action system, and the variation of this class speed can cause the very grave error effect of small arms parts.Too high terminal velocity can cause the premature fatigue of the various parts of small arms, and in whole stroke, excessive action system energy (speed) must consume or dispose as the energy that is produced by the high energy bullet.The consumption of excess energy is finished by the mechanical impact of the unexpected vibrations when the rifle bolt device of small arms and action system stop at the back abut place of action sleeve device usually.Though coupling the bradyseism device soften this bump, the quick decline of action system speed still can pass to each parts with significant inertia load usually, when the higher ammunition of a large amount of shooting energy, might cause premature fatigue and inefficacy.
Therefore, as can be seen, be necessary to design a kind of action rate control system that can handle the small arms of the above-mentioned or problem do not addressed relevant in this technology with other.
Brief summary of the invention
The present invention points to a kind of action rate control system that is used for the small arms of gas-operated.In the embodiment of a demonstration, this action rate control system comprises an action sleeve and a speed of action master cylinder.This action sleeve moves along backward directions according to the burning gases of the certain volume that produces during small arms are opened fire and shift by pore from its gun barrel.This speed of action master cylinder is connected on the action sleeve with the connecting rod that moves and slow down of energy control action sleeve pipe when acting on sleeve pipe near its back abut that moves.The resistance that is produced by the speed master cylinder is its function of speed during action sleeve moves.
In another aspect of this invention, a kind of small arms of gas-operated comprise a gun barrel, a rifle bolt device, an action system and a speed master cylinder that is connected on the action system that is connected on the rifle bolt device.This action system comprises a casing bit, and the latter is subjected to when the ammunition bullet is opened fire the driving of the burning gases of the certain volume that shifts from gun barrel.This speed master cylinder control is by the speed of the casing bit of the combustion gases drive of this certain volume.The resistance that is produced by the speed master cylinder is a rifle bolt device function of speed during the rifle bolt device moves backward.Because absorbed by the speed master cylinder, so the speed of rifle bolt device is followed a kind of controlled and reducing gradually with the relevant energy charge of opening fire.

The action rate control system that provides a kind of small arms to use is provided in the present invention, more specifically is used for small arms such as semi-automatic rifle, shotgun and the pistol of gas-operated.Though the example embodiment of the present invention shown in Fig. 5 is a kind of shotgun that shoots automatically of gas-operated, but the Technology professional will be understood that, speed control system of the present invention also can be applicable to the small arms of the gas-operated of various other types, comprises rifle and other spear and pistol.Speed control system of the present invention do not need basically also to be designed to pressure compensation or input energy adjustment in the small arms of gas-operated.In addition, the invention provides a kind of speed control system that depends on speed, make, no matter the energy input how much, no matter from the high energy bullet or the reduce energy cartrige of ammunition, can more as one man control bolt velocities, thereby reduce to impact and strenuous vibration, and improve the parts of action system and the reliability of function.
As shown in Fig. 3～5, action rate control system 10 of the present invention is installed among the small arms F (Fig. 5) usually, and comprises a speed master cylinder 11 (Fig. 3～5).Speed master cylinder 11 is generally hydraulic cylinder or pneumatic linear actuator, can select this cylinder that resistance levels certain minimum or desirable is provided, or this cylinder can be the variable cylinder of a kind of resistance that can adjust as required.Speed master cylinder 11 generally includes a cylinder bar 12, and cylinder bar 12 can stretch into and stretch out speed master cylinder 11 and be attached on a support plate or the connector 14 at its free end or far-end 13 places.Support plate or connector 14 are connected on action sleeve connector or the connecting rod 16 usually, the latter then be connected on the action system 17 of small arms and by its driving.This action system also comprises an action sleeve device 18 that one or more actuating rods 19 are arranged, and an end of bar 19 connects connecting rod 16 and its other end connects action sleeve 21, and sleeve pipe 21 is installed on the magazine pipe (not shown) of small arms and along its slip usually.
As shown in Figure 5, action sleeve 21 is communicated with the cylinder 22 of firearm barrel 23.Firearm barrel 23 will comprise a series of pore (not shown) that are formed at wherein, thereby the gas that guiding produces from the burning of ammunition or igniting/catch fire is towards casing bit 18 or it is turned to.From pressure impetus sleeve pipe 21 and the actuating rod 19 that these burning gases that turn to come, its direction along arrow 24 (Fig. 3 and 4) is moved backward, so that draw and discharge a bullet of opening fire; Pull striker; Casing bit 18 fails at back terminating point or the place of placing restrictions on; And discharge and load next bullet from magazine, this then throw off action system 17, closure and next bullet of prepare for action.Simultaneously, because action sleeve device quilt is to rear drive, so such motion and energy are passed to speed master cylinder 11 of the present invention by connecting rod 16.As replenishing indication in Fig. 3～5, in 17 operating periods of action system, the rifle bolt device 25 of small arms will stop on the action system 17 and therewith move.
As shown in Fig. 3～5, the present invention utilizes a hydraulic pressure speed control system, wherein the resistance that produces by cylinder be proportional to bolt velocities square, so action sleeve device 18 drives soon more, the resistance that is provided by speed master cylinder 11 is just high more.Usually, the pore system (not shown) that uses is to produce more low-energy shooting (shooting as target practice), thereby will be included in the bigger pore that forms in the gun barrel, holding or the required pressure or the gas volume of overflowing from gun barrel is provided, thereby drive the action system 17 of the small arms of the ammunition that is used to produce minimum energy.
As shown in Figure 2, utilize speed control system of the present invention, when opening fire, when burning gases when the gun barrel of small arms turns to, this action system will be forced to backward.Fig. 2 when further expression utilizes speed control system of the present invention for the generation high energy of opening fire and the comparison of the speed bullet that produces low energy to the curve of time from small arms.As shown in the figure, for two types ammunition, when just opening fire, speed will have a big spike, and the bolt velocities that obtains from opening fire of every bullet will be on its high peak thereon.The bullet that produces higher-energy is illustrated as to have than producing the bigger speed spike of more low-energy bullet.But, with sharp-pointed decline in the termination speed of Small-Arms Weapons System with traditional compensation (wherein the motion of action system or action sleeve device be brought to one unexpected with may strenuous vibration stop) different, the excessive power of action system of the present invention is absorbed by the speed master cylinder and cushions.The result, utilize the present invention, produce (heavy dose of gunpowder) bullet of higher-energy and produce more low-energy (target practice) bullet and follow a similar controlled characteristic curve, this characteristic curve has reduced the vibrations to the action system of small arms significantly, and provide the effect of control more, thereby reduce wearing and tearing and fatigue on it significantly to the parts of the action system of small arms and rifle bolt device.
As also pointing out among Fig. 2, can produce much higher initial bolt velocities though produce the explosive payload of higher-energy, but such bolt velocities is reduced to rapidly usually by producing the terminal bolt speed that more low-energy bullet produced, follow thereafter more in check, meet terminal velocity consistent and that reduce gradually.Therefore, use speed control system of the present invention can set up a very consistent bolt velocities distribution map regardless of the ammunition type of opening fire, thereby provide the more in check mutual mechanism in the cycle of opening fire, this cycle of opening fire is as pulling striker, the system that fails at abut place thereafter, discharge next bullet and throw off action system from magazine, so that closed and prepare next bullet.In addition, comparison shows that of Fig. 1 and Fig. 2 terminal bolt speed, compare with traditional bucking-out system, utilize action rate control system of the present invention, the impact velocity of rifle bolt device and action sleeve device significantly reduces when expiring stroke, thereby reduce to be sent to the inertia force on the action system parts, and reduce the recoil of other undesirable influence such as small arms.
Though the Technology professional is appreciated that top preferred embodiment or the characteristics of disclosing, can carry out variously augmenting, changing and revise and do not depart from its scope and spirit to above-mentioned explanation.
