STRIKER OF APPARATUS FOR CAULKING FILLETS Russian patent published in 2003 - IPC

FIELD: machine engineering, possibly working machine parts by surface plastic deforming. SUBSTANCE: striker is in the form of rod, it has tail portion joined with striking mechanism, mean portion and working portion having deforming surface. Curvature of deforming surface is different in mutually normal axial sections and curvature centers in one of said sections are mutually spaced. Working portion of striker has two spherical lateral surfaces; one of said surfaces is concave and other is convex. Such striker allows to provide optimal quality parameters of hardened surface of fillet in the form of turning inclined by certain angle relative to rotation axis of part and simultaneously to provide carrying capacity of striker at any combinations of geometry parameters of turning. EFFECT: possibility for providing optimal quality factor of hardened surface of fillet. 5 dwg
