DEVICE FOR UNSCREWING OF AMMUNITION DETAILS Russian patent published in 2015 - IPC F42B33/00 F42B33/04 F42B33/06 

FIELD: weapon and ammunition.

SUBSTANCE: invention relates to demilitarisation of ammunition, in particular to unscrewing of ammunition details. A device for unscrewing of ammunition details consists of a frame, a device for ammunition clipping operating in the automatic mode, working unscrewing mechanism and its drive. The drive is implemented as a ratchet mechanism and four pneumatic cylinders. Back covers of the cylinders have eyes with vertical axles of rotation which are located in rectangle tops with a ratio of length of the larger side to the smaller one in a proportion of 1: (0.955-0.975). Axles of rotation of the pneumatic cylinders are located in the opposite tops of the rectangle in the ends of its diagonals, and connected in pairs to the pneumatic circuit of the control system and move synchronously, in antiphase by strokes with ensuring partial overlapping of their strokes.

EFFECT: improvement of safety and automation of the process of remote unscrewing of ammunition details while ensuring the balance of the mechanism due to the mutual compensation of parasitic radial forces in it.
