METHOD OF UNLOADING OF SMALL ARMS-GUN FIXED ROUND Russian patent published in 1998 - IPC

FIELD: unloading of fixed rounds, in particular, unloading of rounds into components (shell, case, powder charge) in automatic conditions. SUBSTANCE: unloading of shell and case is accomplished by successive deformation of the case neck by creating of bending moment around the shell axis. As a result, the shell turns relative to the axis perpendicular to the round axis, the case neck gets deformed. At a reverse motion of the round the direction of action of bending moment on the shell is reversed, the shell is turned, and it is extracted from the shell case. EFFECT: facilitated procedure. 1 dwg
