Problems solved by technology

In the process of separating the bullet holder and the projectile based on the impact separation device of the gun barrel, the high-speed collision between the bullet holder and the separator will cause relative motion of the gun barrel, which will affect the firing accuracy of the projectile
At the same time, after the bullet rest and the bullet rest separator collide and separate, there will be a high-speed rebound and damage the barrel
On this basis, the high-speed impact of the projectile will produce some fragments, which will follow the projectile and act on the target plate at high speed, which will affect the experimental results
[0004] Although the non-impact self-separation avoids the impact effect when the bullet holder is separated, this type of bullet holder will cause separation and scattering, and the bullet holder will scatter to the surroundings at high speed after leaving the gun barrel, causing great safety hazards to laboratory personnel and equipment
At the same time, this type of non-impact self-separation has shortcomings such as incomplete separation and low separation success rate, which cannot guarantee the success rate of the experiment.

Embodiment Construction

[0031] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments, and it should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention.

[0032] A modular spring stock separation device, such as Figure 1~6 As shown, it includes a fastener 1, a front retainer 2, a bomb holder separator 3, and a first-stage debris recovery device 4. Through the cavity, the fastener 1 is a fastening round nut.

[0033] Anterior retainer 2 comprises retainer body 2-1, sealing ring 2-2, the first buckle joint 2-3, and the cross section of retainer body 2-1 is convex shape, and the diameter of its big end is twice of the diameter of small end. Double, the target chamber bulkhead 5 is connected with the outer peripheral surface of the small end of the holder body 2-1 through the fastener 1, the fastener 1 is threaded with the outer perip...

Abstract

The invention discloses a modular sabot separation device. The modular sabot separation device comprises a fastener, a front fixator, a sabot separator and a first-stage fragment recoverer, wherein through chambers are formed in the front fixator, the sabot separator and the first-stage fragment recoverer, and the two ends of the sabot separator are coaxially connected with one end of the front fixator and one end of the first-stage fragment recoverer respectively; and the other end of the front fixator is connected with a bulkhead of a target chamber through the fastener. The invention also discloses a using method of the modular sabot separation device. When the device is used for an impact test, the original device structure does not need to be changed. The device can be independently used for all test equipment. Fragments generated by a sabot and collision can be effectively separated and recycled, the protection effect on experimenters is achieved, and the safety performance is improved. The influence of followers produced by the sabot after collision on an experimental result can be effectively eliminated. The modular sabot separation device is coaxial with a gun barrel, andthe diameters of two separation holes are larger than the diameter of a projectile and smaller than the diameter of the sabot. A ballistic trajectory can be corrected, and experiment failures caused by ballistic trajectory deviation are avoided.

Description

technical field [0001] The invention belongs to the field of material impact dynamics, and in particular relates to a modular bullet support separation device and its application method. Background technique [0002] High-speed impact and penetration experiments are usually carried out with light gas cannons and ballistic guns. Due to the variety of projectile sizes, it is necessary to launch with a projectile carrier to complete the experiment. However, during the experiment, the carrier and the projectile need to be separated before reaching the target to ensure the effectiveness of the experiment. [0003] Existing bullet rest separation devices are mainly divided into two categories: barrel-based impact separation devices and non-impact self-separation devices. In the process of separating the bullet holder and the projectile based on the impact separation device of the gun barrel, the high-speed collision between the bullet holder and the separator will cause relative ...
