APPARATUS FOR KNURLING TOOTHED PROFILES Russian patent published in 1998 - IPC

FIELD: plastic deformation of metals, namely knurling threaded and toothed articles, teeth of cutting tools such as milling cutters, broaches, reamers and so on. SUBSTANCE: apparatus includes drive knurling rollers with shaping profile along their all outer cylindrical contours. Said rollers are mounted through changeable eccentric sleeves on drive shafts. Said shafts are arranged mutually in parallel in housing of machine tool. Their centers are spaced by the same distance from center of blank. Rotation axes of said shafts are misaligned relative to symmetry axes of said rollers by eccentricity value. Eccentric sleeves are joined with shafts by means of key joints. Knurling rollers are mounted on said eccentric sleeves also by means of key joints. EFFECT: improved design. 2 cl, 1 dwg
