Fitting assembly for hood and projectile body

Abstract

The invention provides a fitting assembly for a hood and a projectile body. The fitting assembly is characterized in that the fitting assembly comprises a press machine device and a necking-in devicecorrespondingly matched with the press machine device, the press machine device comprises a machine frame (8) and an air-liquid supercharging cylinder (9), a pressure head (10) is arranged on an output shaft of the air-liquid supercharging cylinder (9), the machine frame (8) is provided with a clamping groove (11) corresponding to the pressure head (10) and a control valve (12) connected and matched with the air-liquid supercharging cylinder (9), and the control valve (12) communicates with an air source through a pressure control valve (13); and the necking-in device comprises an upper die-sleeve (1) and a lower die-sleeve (2) which are coaxially matched, and an expanding portion (2a) correspondingly matched with the clamping groove (11) is arranged at the outer wall of the lower end portion of the lower die-sleeve (2). The fitting assembly has the advantages of being simple in structure, easy to operate, high in safety, low in cost, wide in application, and low in follow-up maintenance expense.

Description

Technical field: [0001] The invention relates to the field of ammunition assembly, in particular to an assembly assembly for a wind cap and an ammunition body. Background technique: [0002] In the assembly process of military products, the sealing technology of the hood and the projectile is used to increase the connection strength between the projectile and the hood, and at the same time plays an important role in the airtightness, stability and aesthetics of the projectile. And most of the existing hood and the body are threaded. But for some specific types of bombs, since the upper and lower parts of the bombs are connected by wires, if the existing spiral mode is still used to connect the hood and the body, it will inevitably affect or even damage the wires. [0003] Moreover, most of the existing closing machines are hand pull presses, which have a low degree of mechanization and rely entirely on manpower to pull the turntable and the handle for multiple times of cont...

And most of the existing hood and body are threaded connection

But for some specific types of bombs, since the upper and lower parts of the bombs are connected by wires, if the existing spiral method is still used to connect the hood and the body, it will inevitably affect or even damage the wires.

[0003] Moreover, most of the existing closing machines are hand pull presses, which have a low degree of mechanization and rely entirely on manpower to pull the turntable and the handle for multiple times of continuous pressurization. The closing pressure consistency is poor, and multiple operators are required for closing at the same time. Large, low shift output and low efficiency

For a certain automatic mouth closing machine, the degree of mechanization is high, there are many circuit devices and sensing elements, and the operation can be completed by a single person, and the working time is about 90 rounds / h, but the purchase price is expensive, the debugging is difficult, and the equipment is bulky , cannot be moved flexibly, and professionals are required to maintain in the follow-up, the maintenance cost is high, and the equipment consumes a lot of electricity. If it is used in the ammunition production workshop, it needs a higher safety guarantee, which greatly increases the ammunition production. cost and production risk
