Description
Technical field
The present invention relates to a kind of casting device, particularly a kind of recoil-free ejecting device.
Background technology
Present casting device generally comprises launching tube, secondary piston, back piston, forward flange, rear flange, ignitron, balanced body and brake hoop.Shell, secondary piston, back piston, ignitron and balanced body all are installed in the launching tube, and secondary piston connects shell, and back piston connects balanced body, and two pistons connect by ignitron, connect brake hoop in the nozzle of two ends.Under the gaseous-pressure effect, two parts before and after ignitron fragments into, front and back piston promote respectively shell and balanced body to launching tube two end motions, are braked by the front and back brake hoop when arriving nozzle, bullet is connected with balanced body and disconnects respectively under the inertia and being connected of front and back piston, and goes out cylinder by certain speed.Present casting device is owing to playing the also reason such as larger of the larger startup of quality and brake force, can only the less shell of launch mass, generally be not more than 2kg, and between launching tube and the bullet without electric interfaces.
Summary of the invention
The object of the present invention is to provide a kind of recoil-free ejecting device, solve between can only the launch mass little shell of present casting device and launching tube and the bullet problem without electric interfaces.
A kind of recoil-free ejecting device comprises: conveyor front barrel, forward flange, middle cylinder body, rear cylinder body, rear flange, balanced body, brake hoop, secondary piston body, back piston, ignitron also comprise: push-pull structure, supporting seat, journal stirrup.Wherein, push-pull structure comprises: housing, compensation linkage and electric connector, and supporting base one end is threaded with the secondary piston body, and the other end is the horn mouth shape, on the horn mouth end face screwed hole is arranged, and journal stirrup one end places in the described screwed hole, and the other end and bullet are spirally connected.Back piston is threaded with balanced body, and middle cylinder body two ends nozzle has screw thread, the two ends nozzle clamping of brake hoop and middle cylinder body, and forward and backward flange and middle cylinder body are spirally connected, and are connected with brake hoop simultaneously.Compensation linkage one end is connected with the housing bearing pin, and the other end is connected with the electric connector bearing pin, and housing is connected with the conveyor front barrel screw, and electric connector is along the transmit direction and the oblique grafting of bullet of bullet.
When the powder charge between secondary piston body and the back piston is burnt, produce high pressure in the cavity between secondary piston body, back piston and middle cylinder body, after pressure increased to certain value, secondary piston body and back piston two parts were separately, previous section promotes the bullet motion, and aft section promotes the balanced body motion.It is anterior that push-pull structure is arranged in cylinder, can not impact the impelling stroke, and the motion by bullet in the impelling process makes the push-pull structure release.When arriving nozzle, secondary piston body and back piston are braked respectively the ring braking, the speed fast-descending, and being connected under the effect of inertia between bullet and supporting base, balanced body and the back piston all broken, and bullet and balanced body go out cylinder by certain speed.
Advantage of the present invention is the impelling problem that has solved large quality, the bullet of electric interfaces is arranged, the recoil when having eliminated emission, the little sound of emission process, little cigarette, low-light.

The specific embodiment
A kind of recoil-free ejecting device comprises: conveyor front barrel 1, forward flange 2, middle cylinder body 3, rear cylinder body 4, rear flange 5, balanced body 7, brake hoop 8, secondary piston body 9, supporting seat 10, back piston 11, ignitron 12 and journal stirrup 13 also comprise: push-pull structure 14.Wherein, push-pull structure 14 comprises: housing 15, compensation linkage 16 and electric connector 17, and supporting base 10 1 ends are threaded with secondary piston body 9, the other end is the horn mouth shape, on the horn mouth end face screwed hole is arranged, journal stirrup 13 1 ends place in the described screwed hole, and the other end and bullet 6 are spirally connected.Back piston 11 is threaded with balanced body 7, and middle cylinder body 3 two ends nozzles have screw thread, the two ends nozzle clamping of brake hoop 8 and middle cylinder body 3, and forward flange 2 and rear flange 5 are spirally connected with middle cylinder body 3, are connected with brake hoop 8 simultaneously.Compensation linkage 16 1 ends are connected with housing 15 bearing pins, and the other end is connected with electric connector 17 bearing pins, and housing 15 is connected with conveyor front barrel 1 screw, and electric connector 17 is along transmit direction and the bullet 6 oblique grafting of bullet 6.
When the powder charge between secondary piston body 9 and the back piston 11 is burnt, produce high pressure in the cavity between secondary piston body 9, back piston 11 and middle cylinder body 3, after pressure increases to certain value, secondary piston body 9 and supporting base 10 separate with back piston 11, supporting base 10 promotes bullet 6 motions, and back piston 11 promotes balanced body 7 motions.Push-pull structure 14 is arranged in conveyor front barrel 1 front portion, can not impact impelling stroke and high-pressure chamber; Plug direction and conveyor front barrel 1 axis is angled, and when bullet 6 travelled forward, the shear action to electric connector 17 had been avoided under bullet 6 high-speed motions in push-pull structure 14 releases.When arriving middle cylinder body 3 nozzle, secondary piston body 9 is braked respectively ring 8 brakings with back piston 11, the speed fast-descending, and being connected under the effect of inertia between bullet 6 and supporting base 10, balanced body 7 and the back piston 11 all broken, and bullet 6 and balanced body 7 go out cylinder by certain speed.In the whole impelling process, combustion gas all is enclosed in the cavity between secondary piston body 9, supporting base 10, back piston 11 and the middle cylinder body 3, accomplishes the little sound of impelling process, little cigarette, low-light.
