HYDRAULIC SHOT-BLAST UNIT FOR SHOT-BLASTING OF PARTS

摘要

FIELD: shot-blasting of cylindrical surfaces of parts. SUBSTANCE: unit is made in the form of chamber filled with working medium. Vertically directed ejector nozzle is mounted in lower part of the chamber and is rotated by means of turbonozzle. Part to be shot-blasted is installed in the upper part of chamber for motion with respect to nozzle head. The used is provided with air-gas main line and bubbling system with areometer. Pneumatic actuator ensures displacement of upper plate and may perform supply of air or gas flow of suspension to supply working medium to surface of part to be shot-blasted. Mounted in pneumatic system may be individual compressor unit. EFFECT: wide possibility of obtaining shot-blasted surface with needed shot-blasted layer featuring definite hardness and roughness. 4 cl, 3 dwg
