APPARATUS FOR VIBRATION WORKING OF ELONGATED PARTS Russian patent published in 2004 - IPC

FIELD: machine engineering, possibly grinding, polishing and strengthening surface layer of parts in containers subjected to low- frequency oscillations. SUBSTANCE: container includes elastically mounted on base shell with vibrator and end walls rigidly mounted on base. End walls have through windows with sealing members and pockets whose bottoms are inclined by angle 35 - 55 degrees towards shell. Bottom of shell is made of half of multistart screw drum cut along its axial line and having sections with the same surface areas. Sections are assembled along perimeter from equilateral triangles inclined by different angles one relative to another and mutually joined by their two sides. Each section is joined with another section by means of free sides of triangles. EFFECT: improved design providing enhanced strengthening degree of surface layer of parts due to compression of working fluid along the whole length of shell during working process. 5 dwg
