Description

[0001] The present invention relates to an internal solid fuel removal device for use in an alveolar cartridge,

[0001] The present invention relates to an apparatus for removing solid fuels in an alveolar casing, which can be installed in a CNC milling machine. More specifically, The present invention is to provide an internal solid fuel removing apparatus having an alveolar casing in which clamping and unclamping of an alveolar shell filled with solid fuel is performed quickly and accurately and the solid fuel is not scattered during the operation.

In the case of shells of 105 mm or more used in canvases and the like, if the elapsed time is 25 to 30 years, the incidence of unexploded blasting due to a primer failure is high.

In the case of shells, although internal gunpowder can be reused, current disposal methods have exhausted the entire shells for practice shooting.

However, in the case of the above-mentioned shell processing, there is a problem such as waste of a reusable explosive, explosion of a large amount of explosive, and environmental pollution.

In recent years, as a means for solving the above-mentioned problem, a disposal method such as disassembling a warhead and a primer part in a shell and detonating only a primer has been proposed.

However, in the case of the solid fuel (gunpowder) filled in the shell, it is impossible to recycle the shell because it is difficult to remove the solid fuel because it is filled with the solid state. Therefore, in the industry, there is a demand for a mechanical device which can securely separate the solid fuel from the alveolar shell In fact.

On the other hand, Korean Patent Publication No. 1019690000084 (1969.04.15) proposes a reclaiming method of waste casings, which can compensate for the mechanical deformation of the waste casings after use to be reused. In this case, the explosive is explosive, so there is no risk of explosion such as melting once.
