MAINTENANCE TOOL FOR COMBINATION HOLE OF 105mm ARTILLERY AMMUNITION DETONATOR AND MAINTENANCE METHOD FOR DISUSE CARTRIDGE CASE OF USING THE SAME}

The present invention relates to a 105mm artillery ammunition capillary hole maintenance fixture of the yakhyeop and a method of maintenance of the primer hole of the yakhyeop using the same, and more specifically, processing the primer hole expanded than the standard prescribed in the bomb yakhyeop maintenance process And standardization of the propellant and detonator, and replacement of the propellant and detonator with new ones, which can be reused without discarding the agreement.

In general, a (high) bomb consists of a fuse and a warhead coupled to the fuse and a contracted couple bound to the warhead.

The fuse is responsible for detonating the high explosives in the warhead when the ammunition is fired by the impact at the target point.Most of the metals and chemicals are piled up in a sealed metal film to prevent long-term use. It is possible.

A warhead is a explosion of high explosives, which causes the carcass to rupture and cause a debris effect and a storm effect.

Yakhyeop is a part surrounding the propellant and the primer, made of brass, and the warhead and yakhyeop are separated, the groove is formed in the inner lower portion, the lower center of the groove is formed in the primer hole.

The high-bombs stored for a long time (about 25 years or more) are now being replaced by new ones after being discarded due to concerns about unexploded bombs due to the outbreak of the agreement and deterioration of the primer.

In the process of separating the primer from the capillary hole of the Yakhyeop, the specification of the primer hole is expanded than the standard standard, and it is not possible to simply replace only the primer because it lacks the technology to reduce the expanded primer hole to meet the standard. Inevitably, a maintenance standard is applied to replace the entire agreement with new products.

This is because when the primer is combined in the expanded state of the primer coupling hole, a minute gap is generated and the gas generated during the explosion leaks into the minute gap and acts as an important coupling element when shooting.

However, this raises a problem that a lot of budget is wasted because all existing agreements must be discarded and new ones must be manufactured and replaced.

In this regard, the present applicant has attempted to solve this problem in Patent Registration No. 10-1209596 (A primer assembly maintenance method and a pact agreement method using the same).

The technical problem to be solved by the present invention, after removing the primer in the yakhyeop can be reused without processing and processing the expanded primer hole to meet the standard specifications of the 105mm artillery ammunition yakhyeop jig maintenance hole and the yakhyeok using the same The present invention provides a method for repairing a primer coupling hole.
