Description

Quenching production line of shell case
Technical Field
The invention belongs to the technical field of quenching equipment, and particularly relates to a quenching production line of a shell case.
Background
A bullet is typically composed of four parts, a warhead, a shell, a primer, and a primer. For good bullets, not only are each component parts excellent in performance, but also the four components are orderly inlaid and closely related to each other to complement each other. The shell is an important component of the bullet, and the shell mainly has the functions of installing primer, filling gunpowder and installing bullet. When the bullet is fired, the bottom edge deforms, the firing pin impacts the primer, the primer detonates the gunpowder, the pressure and the temperature in the bullet shell are suddenly increased, and when the pressure rises to 250-500 kg/cm < 2 >, the bullet is separated from the bullet shell, and starting is started. Therefore, in order to withstand enough pressure, the shell must have a certain hardness, which is otherwise the case with a blow-out, and thus the shell has a certain requirement for hardness in processing.
The manufacturing of the cartridge case mainly consists in processing the metal, and mainly consists in extrusion in principle. However, compared with the bullet shell, the bullet shell has larger length-width ratio, large deformation and higher requirements on processing force and processing temperature. In China, a backward extrusion method is generally used in extrusion manufacturing of the cartridge case. The so-called "extrusion" process is a process in which a softer metal blank is brought into contact with a harder stamping device under tremendous pressure to extrude a designed shape. The basic principle of the backward extrusion method is as follows: the embryo body is fixed, and the metal flows out in the opposite direction to the movement direction of the equipment. After the processing of the reverse extrusion method, the shell cylinder is basically molded, then the waste formed above the shell cylinder is cut off, and the manufacturing process of the shell is basically completed through the cleaning of chemical reagents and the surface treatment of the bottom of the shell.
The manufacturing materials of the shell mainly comprise copper and steel; aiming at the processing technology of the steel shell; in order to ensure the hardness of the steel shell, the steel shell needs to be subjected to quenching treatment, the hardness of the steel shell can meet the requirement, and the existing shell quenching process has a series of problems of large pollution, low resource utilization rate, low automation degree, low efficiency and the like.
