Scrapped submunition bullet fuze unloading machine

Abstract

The invention discloses a scrap shrapnel bullet fuse screwing-off device, relating to the technical field of scrap shrapnel treatment. The scrap shrapnel bullet fuse screwing-off device comprises a machine rack, wherein the upper surface of the machine rack is provided with a pneumatic clamping mechanism, a fuse screwing-off mechanism and a longitudinal feed mechanism; the fuse screwing-off mechanism and pneumatic clamping mechanism are arranged oppositely; and the fuse screwing-off mechanism longitudinally moves by the aid of the longitudinal feed mechanism. The scrap shrapnel bullet fuse screwing-off device can solve the safety problems of small clamping space, wide torque range, interference of the ribbon and fin, bidirectional (left and right) screwing-off, combined shielding fragments, shock waves and metal jet, implements quick screwing-off of bullets with different apertures, has the advantages of high automation degree and high safety performance, and enhances the work efficiency.

Description

technical field [0001] The invention relates to the technical field of scrapped submunition treatment. Background technique [0002] Unloading fuzes of scrapped submunitions is an important process in the technical support activities for the destruction of scrapped submunitions. It has high safety requirements and is difficult to disassemble. The existing scrapped general ammunition destruction equipment cannot meet the requirements of unscrewing fuzes of scrapped submunitions. Unloading the fuze of scrapped submunition bullets has the following requirements and difficulties: [0003] (1) The clamping space is small [0004] The connection between the fuze and the projectile is divided into direct screw connection and indirect screw connection. For the direct screw connection of the fuze and the projectile, the matching thread is generally within 5 buckles. The fuze body is generally divided into the upper half of the special-shaped body and the lower half of the detonator...

AI Technical Summary

Problems solved by technology

For the direct screw connection of the fuze and the projectile, the matching thread is generally within 5 buckles. The fuze body is generally divided into the upper half of the special-shaped body and the lower half of the detonator seat, and is connected with two screws with a diameter of 3 mm. The strength is low; the indirect screw-connected fuze is connected to the projectile through the connecting screw, and the exposed part of the connecting screw is only about 2-3mm, and there are two small gaps on it, which can hold a small space

[0005] (2) Larger torque range

A series of possible problems will be caused after the streamers are scattered: one is that they overlap each other on the transmission chain, so that the bullets cannot advance and retreat normally; the other is that when the tool head is retracted, it will be entangled; , affecting the alignment of the tool head with the two notches on the connecting screw

In addition, after the bullet has been stored for a long time, the spring force of the stabilizer blade spring will also change, the state of the blade is uncertain, it may or may not automatically open, or it may open due to vibration during the transfer process between processes.
