Quenching production line of cartridge case

Abstract

The invention provides a cartridge case quenching production line which comprises an automatic feeding production line, and the automatic feeding production line comprises an automatic feeding system and a quenching system. The automatic feeding system comprises a feeding hopper, a feeding conveying belt, a material distributing bin and a material channel. The feeding conveying belt is arranged between the feeding hopper and a feeding port of the distributing bin. The quenching system comprises a rotating disc and a first induction heater, a plurality of cartridge case positions are uniformly distributed on an outer ring of the rotating disc in the circumferential direction, an outlet of the material channel is aligned to the outer ring position where the cartridge case positions on the rotating disc are located, and along with rotation of the rotating disc, cartridge cases in the material channel sequentially slide into the cartridge case positions on the rotating disc; the first induction heater is arranged corresponding to a part of cartridge case positions on the rotating disc and is arranged at the downstream position of the material channel in the rotating direction of the rotating disc; the first induction heater is used for conducting induction heating on the end opening of the cartridge case, the end opening of the cartridge case is naturally cooled after being heated to the set temperature, and the quenching procedure is completed.

Description

technical field [0001] The invention belongs to the technical field of quenching equipment, and in particular relates to a quenching production line for cartridge cases. Background technique [0002] Bullets are usually composed of four parts: warhead, shell case, propellant and primer. For a good bullet, not only must each component have excellent performance, but the four parts must also be inlaid in an orderly manner, closely related and complementary. Wherein, the cartridge case is an important part of the bullet, and the functions of the cartridge case mainly include installing a primer, filling gunpowder and installing a warhead. When the bullet is fired, the bottom edge is deformed, the firing pin strikes the primer, and the primer detonates the gunpowder, causing the pressure and temperature in the shell to increase sharply. When the pressure rises to 250-500kg / cm2, the bullet breaks away from the shell and starts to fire. Therefore, in order to be able to withstan...
