Abstract

The invention discloses a preparation method of cylindrical controlled fragments. The method includes the steps of material selection, wire drawing, die cutting, screening, nickel plating, detecting and warehousing. According to the method, a medium-carbon steel wire with the hardness of 45-55 HRC, the tensile strength of 1670-1770 MPa and the diameter of 2 mm is selected as the raw material; the cylindrical controlled fragments can deflect or turn over irregularly in the moving process under the action of gravity, air resistance and wind force and have high penetration capability on armored steel plates; when penetrating the human body, high-speed cylindrical controlled fragments can turn over continuously in the tissue of the human body under the resistance of the tissue, irregular cavities with the diameter several times or a dozen times or even dozens of times the bullet diameter are formed in the human body, and the killability of the cylindrical controlled fragments is 4-7 times that of common flaky fragments.

Description

technical field [0001] The invention relates to the technical field of bursting discs, in particular to a method for preparing a cylindrical prefabricated bursting disc. Background technique [0002] On the battlefield, grenades and anti-explosive bombs are the most effective weapons for attacking enemy light armored vehicles, tank fire points, low-altitude flying objects, and active forces. They are the most effective weapons for destroying the enemy and protecting one's own personnel and armored vehicles. The main threat of the chariot comes from the two aspects of fragment kinetic energy damage and explosion shock wave damage. Among them, fragment warheads such as grenades and explosive bombs take into account the damage capabilities of fragments and shock waves, and are used to attack enemy infantry. Potent weapon ammunition for lightly armored vehicles such as tanks. Therefore, it is very necessary to improve the fragmentation lethality of the warhead and the penetrati...
