Problems solved by technology

[0003] At present, the commonly used way to test the firing force of firearms is the prototype simulation test, which is mainly realized by testing the movement speed of the bolt and the size of the depression formed after the primer sample post is fired, and each test consumes a test bullet
So far, there is no quantitative test ammunition that can test the actual firing force generation and change process under typical working conditions during the life cycle of the firearm from the perspective of ammunition force, and can be used repeatedly.

Abstract

The invention provides a reusable filling type test bullet for testing firing force of a firearm, and belongs to the field of firearms. The stress condition of a tested firearm matched bullet after firing is simulated by arranging a primer copper sheet, stress condition data are collected in real time through a sensor, and the stress condition data are sent to an upper computer through a data collecting and transmitting device. The device can be repeatedly used, the size characteristics of the firing force of the firearm under typical working conditions of all stages of different life cycles in the actual firing ignition process can be obtained, and quantitative evaluation of the performance of the firing force of the firearm is achieved through the device.

Description

technical field [0001] The invention relates to the technical field of firearms, in particular to a reusable loading test bullet for testing the firing force of firearms. Background technique [0002] Failure of firearm springs, stuck firing pin movement, improper movement of automatic machines and other reasons will lead to serious failures such as failure to fire and weak firing during the entire life cycle of firearms, greatly reducing the reliability of firearms. By sorting out the failure modes and related components accumulated over the years, the firing mechanism, random factors of the firing mechanism (including component materials, shape, size, coordination, firing drug composition, dose, etc.) and environmental factors that may cause failures are analyzed. According to the analysis, the cause of the failure is related to the firing force. Mastering the change of the firing force of a type of firearm during the life cycle will help to analyze the cause of the failur...
