Abstract
The utility model discloses a heavy-caliber high-load balanced ejecting device which comprises a piston body A (1), a piston body B (2), a wedge-shaped brake ring (5), a skirt-type conical platform (3), a cylindrical support seat (4) and a fixed support joint (6), wherein the skirt-type conical platform (3) is arranged in the piston body A (1) and is in threaded connection with the piston body A (1); the cylindrical support seat (4) is arranged on the front end surface of the piston body B (2) and is in threaded connection with the piston body B (2); in operation, the piston body A (1) and the piston body B (2) are rapidly extruded into a clearance between the wedge-shaped brake ring (5) and an emitting cylinder along a chamfer, and thus the wedge-shaped brake ring (5) generates plastic deformation, is tightly fit on the inner surfaces of an annular structural bodies of the piston body A (1) and the piston body B (2) after deformation until being braked completely. According to the utility model, the own weights and the carrying weights of the piston body A (1) and the piston body B (2) are improved, the structure strength of the mass ejecting device is intensified, and the application field is widened.
Description
Technical field
The utility model relates to a kind of balance casting device, the balance casting device of the high load-carrying of particularly a kind of heavy caliber.
Background technology
Along with the development of balance impelling technology, the balance casting device has had bigger application on the artillery at home, mainly is equipped with air-balance formula recoilless gun and rocket launcher etc.The balance casting device is made up of secondary piston body, back piston body and wedge shape brake hoop; The shortcoming that exists at present is: sole mass is limited with the quality that emission is carried; When needs are launched than the weight body; Bowl-shape piston base impact acceleration is bigger, and centre position well damage is seriously restricting the application of balance casting device.
The utility model content
The purpose of the utility model is to provide the balance casting device of the high load-carrying of a kind of heavy caliber, solves that present piston balance casting device intensity is little, sole mass and emission carry the limited problem of quality.
The balance casting device of the high load-carrying of a kind of heavy caliber comprises: piston body A, piston body B, wedge shape brake hoop also comprise: skirt-type frustum, cylindricality bracket, fixed support joint.Piston body A and piston body B are annulus, and the skirt-type frustum places in the piston body A and is threaded, and the cylindricality bracket places the front end face of piston body B and is threaded.Be evenly distributed with four fixed support joints on the opening surface of skirt-type frustum, the fixed support joint is threaded with the skirt-type frustum.The wedge shape brake hoop is the sphenoid of pipe shape, and chamfering is arranged at the top, and the wedge shape brake hoop places the two ends of balance casting device.
During work, at high-pressure gas stream effect lower piston body A and piston body B to the motion of impelling nozzle direction, when piston body A clashes into the chamfering of wedge shape brake hoop with piston body B; Carry bullet and counterweight under effect of inertia, continue to fly out forward, piston body A breaks the fixed support joint on the skirt-type frustum end face; Piston body B pulls the cylindricality bracket, and piston body A and piston body B get into the gap of wedge shape brake hoop and launching tube fast along chamfering, and the wedge shape brake hoop is under high-speed impact; Produce plastic deformation; Fit tightly ring type structure body inner surface after the distortion at piston body A and piston body B, and along with piston body A and piston body B continue get into, draw close to the center along arc-shaped inner surface; Be braked fully until piston body A and piston body B, high-temperature high-pressure fuel gas is completely enclosed within the impelling tube.
The utility model increases skirt-type frustum and cylindricality bracket on piston body A and piston body B, stressing conditions be improved significantly, structural strength significantly improves; The braking back piston is excellent; Piston body A and piston body B sole mass with carry warhead mass and increase substantially, strengthened security of system and stability, combustion gas is completely enclosed within the launching tube; Realize smokeless, nonflame, Recoilless emission, adapted to the environment for use of densely populated multiple complicacies such as city.

The specific embodiment
The utility model discloses the balance casting device of the high load-carrying of a kind of novel heavy caliber, comprising: piston body A1, piston body B2, wedge shape brake hoop 5 also comprise: skirt-type frustum, cylindricality bracket 4, fixed support joint 6.Piston body A1 and piston body B2 are annulus, and the skirt-type frustum places in the piston body A1 and is threaded, and cylindricality bracket 4 places the front end face of piston body B2 and is threaded.Be evenly distributed with four fixed support joints 6 on the opening surface of skirt-type frustum 3, fixed support joint 6 is threaded with skirt-type frustum 3.Wedge shape brake hoop 5 is the sphenoid of pipe shape, and chamfering is arranged at the top, and wedge shape brake hoop 5 places the two ends of balance casting device.
During work, at high-pressure gas stream effect lower piston body A1 and piston body B2 to the motion of impelling nozzle direction, when piston body A1 clashes into the chamfering of wedge shape brake hoop 5 with piston body B2; Carry bullet and counterweight under effect of inertia, continue to fly out forward, piston body A1 breaks the fixed support joint 6 on skirt-type frustum 3 end faces; Piston body B2 pulls cylindricality bracket 4, and piston body A1 and piston body B2 get into the gap of wedge shape brake hoop 5 and launching tube fast along chamfering, and wedge shape brake hoop 5 is under high-speed impact; Produce plastic deformation; Fit tightly ring type structure body inner surface after the distortion at piston body A1 and piston body B2, and along with piston body A1 and piston body B2 continue get into, draw close to the center along arc-shaped inner surface; Be braked fully until piston body A1 and piston body B2, high-temperature high-pressure fuel gas is completely enclosed within the impelling tube.
