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 provides a device for measuring a cartridge pull force of a center fire sporting cartridge. The device adopts a forward pushing and pressing measurement way; and the cartridge pull forceis measured when a cartridge head is pushed out along the top end of the cartridge. The device is reasonable in structure, high in operation reliability and accurate and stable in test data, can be applied to the production of the 0.32-inch center fire sporting cartridge, and has a remarkable effect. The device and a corresponding measuring method fill the technology gap that a cartridge pull force testing link is in lack in the production and manufacturing process of a Chinese 0.32-inch center fire sporting cartridge, and meanwhile, are applied to cartridge pull force measurement of other similar cartridges adopting a cased telescoped ammunition structure, and have certain technical advancement and generalizability.

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 ...
