Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment:

[0017] see Figure 1~3 As shown, the device for measuring the elastic force of the central firing movement includes a U-shaped base 13, and a slider 11 is installed in the opening cavity of the base 13, and a through hole is processed at the center of the slider 11. The through hole The sample 12 used to measure the pull-out force of the central firing movement with a caliber of 0.32 inches is installed inside, and a step is processed in the center through hole of the slider 11 to resist the flange of the sample 12 shell to prevent the shell from being ejected with the bullet 14 eject together. A thimble 14 for pushing the projectile on the sample 12 is arranged at the bottom of the opening cavity of the base 13, and a step is processed in the central through hole of the slider 11 to be used for resisting the flange of the cartridge case of the sam...

Abstract

The invention relates to a device for measuring the pull-out elastic force of the central firing movement. The device adopts a positive pushing measurement method, and measures the pull-out elastic force while pushing the bullet out along the top direction of the bullet. The device has reasonable structure, high operational reliability, and accurate and stable test data. It has been applied to the production of 0.32-inch center-fired sporting bullets and achieved remarkable results. The device and the corresponding measurement method fill the technical gap in the testing process of the pull-out force in the production and manufacture of 0.32-inch center-fired sporting bullets in China, and are also applicable to the pull-out force measurement of other bullets that adopt a countersunk structure similar to bullets, and have certain technological advancement and scalability. sex.

Description

technical field [0001] The invention relates to a device for measuring the pulling elastic force of the central firing movement, which belongs to the technical field of machinery. Background technique [0002] The 0.32-inch center sports ammunition is a competitive ammunition commonly used in military sports competitions. Its main features: low muzzle velocity, small dispersion accuracy, consistent muzzle vibration and stable burst performance. As the main technical index of the ammunition, the pull-out force cannot be measured by the traditional method of loading and unloading the cartridge case because of the structure of the countersunk bullet. Contents of the invention [0003] The present invention is designed to provide a device for measuring the pull-out force of a center-fired bullet aimed at the above-mentioned problems in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The device for ...
