Abstract
Description
Technical Field
[0001] The utility model relates to a bullet, in particular to a spiral bullet with strong armor-piercing ability. Background Art
[0002] Current bullets are typically made of traditional metals like iron and copper, with a smooth, flat surface. These bullets generally have low armor-piercing capabilities. To improve armor-piercing capabilities, alloys with stronger armor-piercing properties must be used. However, these alloys are very expensive. Utility Model Content
[0003] The purpose of this utility model 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 utility model includes a shell, a core and a powder core, the shell is covered on the outside of the core, the core has an internal hollow structure, and the powder core is filled in the core; a spiral pattern is provided around the central axis on the outside of 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 by the spiral pattern during the acceleration process 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 an amorphous material. Amorphous shells have high hardness and strong self-sharpening properties, enabling them to quickly penetrate armor plates, effectively improving the projectile's armor-piercing capability. Furthermore, the manufacturing process for amorphous materials is mature and simple, thus helping to reduce the production cost of the projectile.
[0007] Specifically, the shell is provided with an amorphous hardened layer on its surface. This layer increases the shell's hardness and facilitates grinding against armor under the high-speed rotation of the warhead, thereby improving armor-piercing capability. Furthermore, the amorphous hardened layer breaks into more particles after the warhead explodes, increasing its 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 core is made of tungsten material, which can improve the armor-piercing capability of the bullet.
[0010] Specifically, the bullet 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, the head of the projectile core is provided with a drill bit structure. 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 projectile 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 effects achieved by the present invention in detail, the following is a detailed description in conjunction with the embodiments 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. The shell 1 is coated on the outside of the core 2. The core 2 has an internal hollow structure 21, and the powder core 3 is loaded into the core 2. The powder core 3 is made of a high-enthalpy amorphous powder material, which is a high-explosive powder that greatly enhances the lethality of the bullet. The shell 1 is provided with a spiral pattern 11 around the central axis, and the spiral pattern 11 protrudes outward relative to the surface of the shell 1. The shell 1 is made of an amorphous material and is wrapped around the outside of the core 2 by vacuum 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 properties. It can quickly drill into the interior of the armor plate, effectively improving the armor-piercing capability of the bullet. In addition, the process for making amorphous materials is mature and simple, which is conducive to reducing the production cost of the bullet. The surface of the shell 1 is provided with an amorphous hardened layer 12. Specifically, after the shell 1 is placed at 180 degrees Celsius for 30 minutes, the material near the surface forms an amorphous hardened layer 12. This amorphous hardened layer 12 contains 18% of a hardened phase composed of Al, Zr, or Cuτ3. This amorphous hardened layer 12 increases the hardness of the shell 1 and facilitates armor grinding under the high-speed rotation of the warhead, thereby improving armor-piercing capability. Furthermore, the amorphous hardened layer 12 breaks into more particles after the warhead explodes, increasing its lethality.
[0021] The core 2 is made of tungsten. Specifically, it is formed from a bundle of twisted tungsten wires. The diameter of the tungsten wires is 0.15-0.5 mm. This improves the armor-piercing capability of the warhead. Furthermore, upon explosion, the tungsten wires disperse to expand the impact area, enhancing the warhead's lethality.
[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. This drill bit structure 22, under the action of the warhead's rotational force, can effectively drill and cut armor, enhancing the warhead's armor-piercing capability. Specifically, the drill bit structure 22 has an opening 23, the inner side of which is provided with an inclined surface 231. The diameter of the opening 23 gradually increases as it approaches 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 by the spiral pattern 11 during acceleration in the bore, thereby accelerating the cutting and penetrating of the armor plate under the action of high-speed rotation, thereby effectively improving the armor-piercing capability 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.
