Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Referring to fig. 1, the present utility model provides the following technical solutions: the shell 1 is covered outside the liner body 2, medicine 3 is filled between the inner wall of the shell 1 and the outer wall of the liner body 2, a jet hole 11 is formed in the top end of the shell 1, a powder guiding pack 4 for igniting the medicine 3 is arranged in the jet hole 11, the liner body 2 is in a single conical shape, the outer wall at the bottom end of the liner body 2 is in interference fit with the inner wall of the shell 1, the bilateral angle of the section cone angle of the outer wall of the liner body 2 is 50-60 degrees, and the thickness of the liner body 2 is 20-50 mm;

because the liner body 2 is in a single cone shape, the single cone processing technology is mature and reliable, the jet head speed and jet energy are enabled to be more temperature, the cone angle is a main parameter for determining the jet head speed and the nail breaking depth, the jet head filling speed is increased along with the decrease of the cone angle of the liner body 2, the bilateral angle of the liner is generally 35-62 degrees, and the test shows that when the cone angle of the liner body 2 is smaller, the metal jet is thin and long, the stability is poor, and the similar product is used for reference and analysis, so that the liner cone angle can be properly larger; therefore, the angle of taper is selected to be 50-60 degrees on both sides.

Further, as shown in fig. 1, the liner body 2 is made of a red copper material, and the liner body 2 is required to have high density and good plasticity, and is not easy to vaporize in the jet flow forming process, and red copper has the characteristics of high density, good plasticity, excellent performance of the armor compared with cast iron steel, aluminum and other materials, so that the red copper material is selected.

Further, as shown in fig. 1, a deep penetration material layer 5 is provided on the outer wall of the liner body 2.

Further, as shown in fig. 1, the bottom end cover of the liner body 2 is provided with a heat shield 6, and the outer wall of the bottom end of the heat shield 6 is in transition fit with the inner wall of the bottom end of the shell 1.

Further, as shown in fig. 1, the bottom end cover of the heat shield 6 is provided with a buffer cover 7, a buffer cavity 71 is formed between the outer wall of the buffer cover 7 and the inner wall of the heat shield 6, and the outer wall of the bottom end of the buffer cover 7 is welded and fixed with the inner wall of the heat shield 6.

Further, as shown in fig. 1, a cushion pad 8 is provided in the cushion chamber 71.

When the explosive-guiding bag is used, the explosive-guiding bag 4 ignites the inner explosive 3, the inner explosive 3 burns to generate metal jet and is ejected by the jet hole 11, the explosive-guiding bag 4 continues to burn and ignites the deep penetrating material layer 5 to ignite, the deep penetrating material layer 5 ignites and then secondary explosion releases energy, the pressure in the cartridge case 1 is improved, and the ejection speed through the metal jet is further improved, so that is the nail breaking effect is improved, meanwhile, the pressure generated by the inner explosive 3 and the deep penetrating material layer 5 can act on the liner body 2, the liner body 2 can displace towards one end far away from the jet hole 11 under the action of the pressure, the liner body 2 displaces, the heat-insulating cover 6 is acted on under the action of the pressure, the buffer cover 7 supports the buffer cushion 8, the buffer cushion 8 absorbs and continuously buffers the force transmitted by the buffer cushion 8, and meanwhile, the high heat generated when the inner explosive 3 and the deep penetrating material layer 5 are burnt is prevented from being transmitted to the buffer cushion 8, and deformation caused by the high heat of the buffer cushion 8 is avoided.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
