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.
