Abstract
Description
Technical Field
[0001] The invention relates to a bullet, in particular to a spiral bullet with strong armor-piercing ability. Background Art
[0002] Today's bullets are generally made of traditional metal materials such as iron and copper, and the surface of the bullet is a flat and smooth structure. The armor-piercing ability of such bullets is generally not strong. To improve the armor-piercing ability of the bullet, alloy materials with stronger armor-piercing ability must be used. However, the price of these alloy materials is very expensive. Summary of the invention
[0003] The purpose of the present invention is to provide a spiral bullet with strong armor-piercing ability and low cost.
[0004] In order to achieve the above-mentioned purpose, the spiral bullet provided by the present invention includes a shell, a core and a core, the shell is coated on the outside of the core, the core is an internal hollow structure, and the core is filled in the core; a spiral pattern is provided around the central axis outside the shell, and the spiral pattern protrudes outward relative to the surface of the shell.
[0005] Compared with the prior art, the present invention provides a spiral pattern around the central axis outside the shell, and the spiral pattern protrudes outward relative to the surface of the shell, so that the bullet can be accelerated to rotate through the spiral pattern during acceleration in the bore, so that the bullet can accelerate the cutting and penetrating of the armor plate under the action of high-speed rotation, thereby effectively improving the armor-piercing ability of the bullet, reducing the cost, and making the flight of the bullet more stable.
[0006] Preferably, the shell is made of amorphous material. The shell made of amorphous material has high hardness and strong self-sharpening performance, and can quickly drill into the interior of the armor plate, effectively improving the armor-piercing ability of the warhead. In addition, the process of making amorphous materials is mature and simple, so it is conducive to reducing the production cost of the warhead.
[0007] Specifically, the surface of the shell is provided with an amorphous hardened layer. The amorphous hardened layer can increase the hardness of the shell and is conducive to grinding the armor under the power of the high-speed rotation of the warhead, thereby improving the armor-piercing ability. In addition, the amorphous hardened layer can also be broken into more particles after the warhead explodes, increasing the lethality.
[0008] Specifically, the shell is placed at 180 degrees Celsius for 30 minutes, and the amorphous hardened layer is formed on the surface of the shell.
[0009] Preferably, the bullet core is made of tungsten material, which can improve the armor-piercing ability of the bullet.
[0010] Specifically, the core is made of a bundle of tungsten wires.
[0011] Specifically, the diameter of the tungsten wire is 0.15-0.5 mm.
[0012] Preferably, a drill bit structure is provided at the head of the projectile core. By providing the drill bit structure, under the action of the rotational power of the bullet, the drill bit structure can perform a strong drilling and cutting action on the armor, thereby enhancing the armor-piercing capability of the bullet.
[0013] Specifically, the drill bit structure is provided with an opening, and the diameter of the opening gradually increases in a direction approaching the head of the core.
[0014] Specifically, the drill bit structure is provided with an opening, and the diameter of the opening is 0.3-1.8 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.
[0020] like Figure 1 and Figure 2As shown, the spiral bullet 100 of the present invention includes a shell 1, a core 2 and a powder core 3, wherein the shell 1 is coated on the outside of the core 2, the core 2 is an internal hollow structure 21, and the powder core 3 is loaded in the core 2; the powder core 3 is a high enthalpy amorphous powder material, which is a high explosive powder, greatly enhancing the lethality of the bullet. A spiral pattern 11 is arranged around the central axis outside the shell 1, and the spiral pattern 11 protrudes outward relative to the surface of the shell 1. The shell 1 is made of amorphous material, which is wrapped around the outside of the core 2 by vacuum suction casting; specifically, it is made of Zr, Cu, Al, Ni or Ti amorphous alloy material. The shell 1 made of amorphous material has high hardness and strong self-sharpening performance, and can quickly drill into the interior of the armor plate, effectively improving the armor-piercing ability of the bullet. In addition, the process for making amorphous materials is mature and simple, so it is conducive to reducing the production cost of the bullet. The surface of the shell 1 is provided with an amorphous hardening layer 12. Specifically, the shell 1 is placed at 180 degrees Celsius for 30 minutes, and the material near the surface will form the amorphous hardened layer 12; the amorphous hardened layer 12 has 18% Al, Zr or Cuτ3 hardened phase. The amorphous hardened layer 12 can increase the hardness of the shell 1, and is conducive to grinding the armor under the power of the high-speed rotation of the warhead, thereby improving the armor-piercing ability. In addition, the amorphous hardened layer 12 can also be broken into more particles after the warhead explodes, increasing the lethality.
[0021] The core 2 is made of tungsten material. Specifically, the core 2 is made of a bundle of tungsten wires. The diameter of the tungsten wires is 0.15-0.5 mm. This can improve the armor-piercing ability of the warhead. In addition, the tungsten wires can be dispersed during the explosion to expand the killing area and improve the killing ability of the warhead.
[0022] For example Figure 2 , Figure 3 and Figure 4 As shown, the head of the core 2 is provided with a drill bit structure 22. By providing the drill bit structure 22, under the rotational power of the bullet, the drill bit structure 22 can perform a strong drilling and cutting action on the armor, thereby enhancing the armor-piercing capability of the bullet. Specifically, the drill bit structure 22 is provided with an opening 23, and an inclined surface 231 is provided on the inner side of the opening 23. The diameter of the opening 23 gradually increases in the direction close to the head of the core 2. The diameter of the outermost opening 23 of the drill bit structure 22 is 0.3-1.8 mm.
[0023] Compared with the prior art, the present invention provides a spiral pattern 11 around the central axis outside the shell 1, and the spiral pattern 11 protrudes outward relative to the surface of the shell 1, so that the bullet can be accelerated to rotate through the spiral pattern 11 during the acceleration process in the bore, so that the bullet can accelerate the cutting and drilling through the armor plate under the action of high-speed rotation, thereby effectively improving the armor-piercing ability of the bullet, reducing the cost, and making the flight of the bullet more stable.
[0024] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
