DEVICE FOR THERMAL IMPULSE REMOVAL OF BURRS FROM ITEMS Russian patent published in 2008 - IPC B23K7/06 B21D26/08 B23K28/00 

FIELD: technological processes; electricity.

SUBSTANCE: system of self-locking chamber (1) is equipped with cock-pipe system of control of fuel charge burning process duration and system of chemical absorption of produced carbonic gas. Movable bottom (6) of chamber (1) is arranged in the form of bucket turned upside down that rests with its annular butt end onto hydraulic cushion (10). In one of pipelines that are going to air-hydraulic accumulator (13), one-sided action valve (12) is installed, which passes liquid only to accumulator (13), and in the other pipeline that bypasses one-sided action valve (12) plunger (8) is installed that interacts with movable annular belt (4) of chamber. One-sided action valve (15) is also installed in gas discharge line (14).

EFFECT: higher reliability of fuel charge burning duration control system with guaranteed complete cleaning of chamber from combustion products and liquidation of carbonic gas exhaust into atmosphere.
