the tungsten ring is uniformly provided with a plurality of processing grooves, so that a thin wall is formed between each processing groove and the tungsten ring.
Further, the tungsten ring adopts high-density tungsten alloy, and the density value is not less than 17g/cm 3
Further, the length dimension of the explosive is larger than that of the round cavity on the inner wall of the projectile body.
Furthermore, the front end of the projectile body is provided with a hood which is a cone with an inner cavity, and the front end of the projectile body is connected with the bottom of the inner cavity of the hood through a threaded structure at the bottom of the armor-piercing block.
Further, the projectile body is provided with a bottom screw for sealing the projectile body.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
1. the utility model discloses a tungsten ring is established to outer pot head at the explosive to tungsten ring outside makes its local strength weak through the processing groove, and explode the tungsten ring when the explosive explodes and split, solve present projectile body fragment effect in-process fragment formation uncontrollable with this, inhomogeneous, phenomenon such as speed decay is fast, hit target probability, the first-wearing ability, destroy the effect with reaching the improvement fragment, and reduce fragment structure technical difficulty, simplify processing technology, improve assembly efficiency, reduce cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1-3, the utility model provides a projectile body prefabricated fragment tungsten ring structure, which comprises a projectile body 1, wherein an explosive 4 is filled in the projectile body 1, a circular cavity is arranged on the inner wall of the projectile body 1, a plurality of tungsten rings 5 are sleeved outside the explosive 4 and are positioned in the cavity, the tungsten rings 5 are sleeved at the outer ends of the explosive 4, so that the tungsten rings 5 are propelled outwards when the explosive 4 is burst,
the tungsten ring 5, tungsten ring 5 outside evenly sets up a plurality of processing groove 51, makes to form the thin wall form between processing groove 51 and the tungsten ring 5, makes tungsten ring 5 form a plurality of even fragments when exploding through processing groove 51 to can adjust the fragment of different quantity through increasing processing groove 51, process more portably.
Wherein, the tungsten ring 5 adopts high-density tungsten alloy, and the density value is not less than 17g/cm 3 The anti-compression stress and the anti-deformation capacity are improved, the stress deformation caused by detonation during detonation is effectively prevented, the number of fragments is increased, and the armor piercing kinetic energy is improved.
