Abstract
The invention discloses a skirt-type impact-resistant overload device which comprises a wedge-shaped brake ring (2), a bowl-shaped piston body (1) and a skirt-type horn (6). The wedge-shaped brake ring (2) is a cylindrical wedge-shaped body, the bottom of the wedge-shaped brake ring (2) is of a fixed boss structure (3), ant the top of the wedge-shaped brake ring (2) is of an oblique section structure (4); the bottom of the bowl-shaped piston body (1) is a plane, and the top of the bowl-shaped piston body (1) is of an annular structure (5); the skirt-type horn (6) is screwed with the bowl-shaped piston body (1); four fixed support joints (7) are uniformly distributed on the opening surface of the skirt-type horn (6); and when in operation, the annular structure (5) of the bowl-shaped piston body (1) rapidly squeezes into the clearance between the wedge-shaped brake ring (2) and a transmission cylinder along the oblique section structure (4), and the wedge-shaped brake ring (2) generates plastic deformation and tightly fits on the inner surface of the annular structure (5) after deformation until braking is completed. According to the invention, the self weight and carrying weight of the bowl-shaped piston are improved, and the application field is widened further.
Description
Technical field
The present invention relates to a kind of shock resistance overload device, particularly a kind of skirt-type shock resistance overload device.
Background technology
The buffer structure that uses at present is that the plastic deformation with element comes energy-absorbing to reach the purpose of buffer-braking; Be widely used on ballistic mortar, the individual rocket big gun; The shock resistance overload device that present stage adopts comprises: bowl-shape piston body and wedge shape brake hoop, bowl-shape piston body are positioned at the bore middle part, and the wedge shape brake hoop is positioned at the bore outlet; The shell head is radially spacing by the wedge shape brake hoop, and the shell afterbody is undertaken circumferentially and axial limiting by bowl-shape piston.Bowl-shape piston promotes shell and goes out thorax at a high speed during emission under the gas-flow effect; When bowl-shape piston slap wedge shape brake hoop; Utilize the bowl edge material gradually the characteristics of thickening force the wedge shape brake hoop to produce plastic deformation; Reach the purpose of fast cache braking, the material that the wedge shape brake hoop is extruded when producing plastic deformation can radially piled up, and changes radial dimension.But the bracket of present bowl-shape piston is connected with bowl-shape piston body through the column screw thread; Sole mass is all limited with the quality that emission is carried; When needs were launched than the weight body, bowl-shape piston base impact acceleration was bigger, centre position well damage; There is big defective, seriously restricting the application of buffer unit.
Summary of the invention
The object of the present invention is to provide a kind of skirt-type shock resistance overload device, it is little to solve present bowl-shape buffer piston device intensity, and sole mass carries the limited problem of quality with emission.
A kind of skirt-type shock resistance overload device comprises: wedge shape brake hoop, bowl-shape piston body also comprise: the skirt-type loudspeaker.The wedge shape brake hoop is the sphenoid of a pipe shape, and the bottom is the fixing lug boss structure, and the top is the oblique section structure.Bowl-shape piston body bottom is the plane, and the top is a ring type structure, and skirt-type loudspeaker and bowl-shape piston body are spirally connected, and 4 fixed support joints that are uniformly distributed with are arranged on the skirt-type loudspeaker opening surface, and fixing branch fastener and skirt-type loudspeaker are spirally connected.
During work, bowl-shape piston body is at a high speed to launching the motion of nozzle direction, when the structure of the oblique section of bowl-shape piston body bump wedge shape brake hoop under the effect of high-pressure gas stream; Carry bullet under effect of inertia, continue to fly out forward, and break the fixed support joint on the skirt-type loudspeaker end face; Ring type structure is got into the gap of wedge shape brake hoop and launching tube fast along the oblique section, the wedge shape brake hoop produces plastic deformation under high-speed impact; Closely be fitted in the inner surface of the ring type structure of bowl-shape piston body after the distortion; And along with bowl-shape piston body continue to get into effect, draw close to the center along arc-shaped inner surface, until bowl-shape piston body by braking fully.
This device increases the skirt-type loudspeaker on bowl-shape piston body; The stressing conditions of whole piston be improved significantly, structural strength significantly improves, the braking back piston is excellent bad; Bowl-shape piston body sole mass with carry warhead mass and increase substantially, strengthened security of system and stability.

The specific embodiment
A kind of skirt-type shock resistance overload device comprises: wedge shape brake hoop 2, bowl-shape piston body 1 also comprise: skirt-type loudspeaker 6.Wedge shape brake hoop 2 is the sphenoid of a pipe shape, and the bottom is a fixing lug boss structure 3, and the top is an oblique section structure 4.Bowl-shape piston body 1 bottom is the plane, and the top is a ring type structure 5, and skirt-type loudspeaker 6 are spirally connected with bowl-shape piston body 1, are uniformly distributed with 4 fixed support joints 7 on skirt-type loudspeaker 6 opening surfaces, and fixing branch fastener 7 is spirally connected with skirt-type loudspeaker 6.
During work, bowl-shape piston body 1 is at a high speed to launching the motion of nozzle direction, when the structure 4 of the oblique section of bowl-shape piston body 1 bump wedge shape brake hoop 2 under the effect of high-pressure gas stream; The bullet that carries continues to fly out forward, and breaks the fixed support joint 7 on skirt-type loudspeaker 6 end faces under effect of inertia; Ring type structure 5 is got into the gap of wedge shape brake hoop 2 and launching tube fast along the oblique section, wedge shape brake hoop 2 produces plastic deformation under high-speed impact; Closely be fitted in the inner surface of the ring type structure 5 of bowl-shape piston body 1 after the distortion; And along with bowl-shape piston body 1 continue to get into effect, draw close to the center along arc-shaped inner surface, until bowl-shape piston body 1 by braking fully.
