Device for collecting and releasing copper cylinder and copper ball pressure gauge

Abstract

The invention discloses a device for collecting and releasing a copper cylinder and copper ball pressure gauge, aiming at solving the technical problem that the copper cylinder and copper ball pressure gauge is hardly immobilized in a metal cartridge of propellant charge. The collecting and releasing device of the invention consists of an upper positioning plate, a positioning colloidal silica, alower positioning plate, a colloidal silica bottom cushion, a central tube and a fastening device, wherein the upper positioning plate is positioned at the upper part of the collecting and releasing device, the positioning colloidal silica is disposed below the upper positioning plate, the lower positioning plate is disposed below the positioning colloidal silica, and the colloidal silica bottom cushion is disposed below the lower positioning plate. The device of the invention is applied mainly to the dynamic screening of the copper cylinder and copper ball pressure gauge.

Description

technical field [0001] The invention relates to a collection and release device for dynamic identification of copper pillars and copper ball pressure gauges. Background technique [0002] Bore pressure is one of the important tactical and technical indicators of various weapon systems. It is a necessary parameter to evaluate the use and safety performance of products including guns, cannons, automatic weapons, bullets, fuzes, and propellants. Extremely important characteristic parameters of multiple links in production and product verification. The plastic deformation manometric method has many advantages such as easy to use, only one plastic manometer (plastic sensitive element copper column, copper ball manometer), simple operation, stable and reliable data, and economical. Therefore, it is widely used in various guns. The scientific research and production of guns, ammunition and medicine are used by military enterprises, scientific research institutes and test bases all...

AI Technical Summary

Problems solved by technology

This method has the following problems. When the cartridge is pressed into the position of the bottom of the gun bore, the copper column and the copper ball pressure gauge will move with the movement of the propellant layer; The ball manometer may have a large displacement, break away from the bottom of the cartridge, or even enter the gun barrel, which will affect the selection of the copper column and copper ball manometer; in addition, the copper column and copper ball manometer will contact the bottom of the cartridge. collided with each other, resulting in damage to the copper column and copper ball pressure gauge
