Description

Technical Field

[0001] The present invention relates to the technical field of semi-enclosed explosive devices, in particular to a semi-enclosed explosive device used for testing the inner bore material of a gun barrel. Background Art

[0002] A semi-closed explosive is a device used in the fields of mechanics, chemical engineering, and materials science. It is primarily designed to handle high-pressure, high-temperature reactions, particularly those involving combustion or explosion. Unlike fully closed reactors, semi-closed explosives allow a certain amount of gas or liquid flow while maintaining the high pressure or temperature in the reaction environment, making the reaction more controllable and improving efficiency.

[0003] The existing semi-enclosed explosive device is mainly used to test the performance of gunpowder primer, plasma diagnosis, and as a plasma generator, or burning rate test, pressure-temperature-time change calculation method, for rocket solid propellant velocity measurement, the main structure is as follows Figure 1 As shown in FIG, its operating principle is as follows: ignition is performed by electric shock at the rear end of a semi-enclosed explosive device, and gunpowder 102 burns in a space container 101. When the air pressure reaches a certain level, it breaks through the pressure control plate 302, and the gas is discharged, achieving the performance of gunpowder combustion. The plasma generator also works in the same way. The existing technology mainly uses fixed-volume semi-enclosed explosive devices or enclosed explosive devices to test the relevant properties of gunpowder. However, there is no method for analyzing and testing the performance of the metal materials in the inner chamber of the gun. The main problem is to test and analyze the burning rate, temperature and other properties of the gunpowder material or related propellants.

[0004] The traditional artillery squeeze test equipment has a relatively simple structure, such as Figure 2 As shown, the pneumatic launch method used to simulate the projectile's penetration process makes it difficult to simultaneously control multiple variables or simulate complex gas flows and chemical reactions. It is difficult to fully simulate the actual environmental conditions during artillery firing, such as instantaneous high temperatures, high pressures, gas flow rates, and chemical reactions. This can lead to deviations between test results and actual performance under actual use conditions.

[0005] In the existing technology, the sealing and structural design of the equipment may cause wear or deformation after a long period of time or multiple tests, resulting in a decrease in the sealing effect and unstable internal pressure, which in turn affects the repeatability of the test. Some test equipment has difficulty maintaining consistent test conditions when conducting multiple tests, resulting in large differences between different test results. This affects the reliability and comparability of the test data. In addition, the needs of modularity and rapid replacement are not fully considered in the design of the equipment. The internal structure may be too complex or integrated, resulting in a lot of time required to disassemble, replace and reinstall materials after each test. Especially when a large number of tests are required, the time cost is increased.

[0006] In view of the above problems, the present invention proposes a semi-enclosed explosive device for testing the inner bore materials of a gun barrel. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] The present invention proposes a semi-closed explosive device for testing the inner bore material of a gun barrel, comprising a semi-closed explosive device body 11, a powder chamber 5 being arranged inside the semi-closed explosive device body 11, a temperature sensor interface 12 being arranged on the semi-closed explosive device body 11 corresponding to the powder chamber 5, a pressure sensor interface 6 being further arranged on the side opposite to the temperature sensor interface 12, the pressure sensor interface 6 passing through the semi-closed explosive device body 11 and being connected to the powder chamber 5; bolt plugs and adjusting bolts are connected at both ends of the semi-closed explosive device body 11, the bolt plugs comprising a first bolt plug 7 and a second bolt plug 9, and the adjusting bolts comprising a first adjusting bolt 10 and a second adjusting bolt 14; a gun inner bore material testing device is further arranged inside the semi-closed explosive device body 11, and the gun inner bore material testing device comprises a pressure control plate 2, a cylindrical core rod 3, a sample 4 and an electronic ignition device 8.

[0032] Among them, the first bolt plug 7 is spirally connected to one side of the semi-closed exploder body 11, and a first sealing ring 15 is provided at the connection between the first bolt plug 7 and the inner wall of the semi-closed exploder body 11. The first sealing ring 15 is a copper sealing ring; the first adjusting bolt 10 is spirally connected to the inside of the first bolt plug 7, and the first adjusting bolt 10 is provided with an exhaust channel 1, the pressure control plate 2 is fixedly installed inside the exhaust channel 1, the cylindrical core rod 3 is fixedly installed at the inner end of the first adjusting bolt 10 by bolts, and the sample 4 is sleeved on the outside of the cylindrical core rod 3.

[0035] When the semi-enclosed explosive device needs to be equipped with a projectile, it is only necessary to unscrew the cylindrical core rod 3 at the position of the pressure control plate 2 and the exhaust channel 1 through the first adjustment bolt 10 and replace the projectile. The whole process is convenient and fast, and the scheme can be changed by replacing parts without changing the semi-enclosed explosive device body.
