INSTALLATION FOR SHOCK-VIBRATING PROCESSING OF LONG PARTS Russian patent published in 2014 - IPC B24B31/06 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for finish machining of part surfaces in containers vibrating at low frequency. Proposed installation of container consisting of shells ring with vibrator arranged at the bed and end walls rigidly mounted at said bed. Said end walls have through openings and pockets under bottom at the angle of 35°-55° towards said shell ring composed of helical drum half, said drum being cut in axial line and mounted of multistart helical drum sections. Sections consist of two subsections composed by three and more isosceles trapeziums and isosceles triangles with interconnected lateral sides and bases in subsection are opposed. Said sections are interconnected by larger bases of trapeziums. Said subsections are integrated in section so that isosceles triangle bases of one subsection are connected with top base of isosceles trapeziums of second subsection while isosceles triangle bases of second subsection are connected with top base of isosceles trapeziums of first subsection.

EFFECT: higher efficiency of processing, expanded performances.
