The invention concerns a method for the debarring of items, especially metal items (1), which are encumbered with sharp edges or burrs (8) after punching, clipping, moulding and/or machining operations, by which method the items (1) are fed in under a debarring tool which sweeps the surface of the items (1), said debarring tool comprising a number of debarring rollers (21), each of which is secured to an individual spindle axle (22) which extends radially outwards from a drive (23), said debarring rollers (21) being rotated around the spindle axles (22) and also being turned around a turning axle (24) which extends at right-angles to the spindle axles (22), in that the debarring rollers (21) are also moved in a reciprocating manner parallel with the surface (2) of the items (1) in a direction transversely to the feeding direction (28) of the items (1). The invention also concerns the use of said method for the debarring and/or grinding of ribs for aircraft wings or similar objects.
L'invention porte sur un procédé d'ébavurage d'articles notamment d'articles métalliques (1) présentant des arêtes coupantes ou des bavures (8) suite à des opérations d'étampage, de détourage, de moulage et/ou d'usinage. Ledit procédé consiste à amener les articles (1) sous un outil à ébavurer balayant la surface de l'article (1) et qui comporte plusieurs rouleaux ébavureurs (21) montés sur des axes de rotation distincts (22) s'étendant radialement vers l'extérieur à partir d'un entraînement (23). Lesdits rouleaux (21) tournent autour desdits axes de rotation (22) et également autour d'un axe central (24) perpendiculaire aux axes de rotation (22). Les rouleaux ébavureurs (21) sont également animés d'un mouvement oscillant parallèle à la surface (2) des articles (1) et transversalement au sens d'introduction (28) des articles (1). L'invention porte également sur l'utilisation dudit procédé pour l'ébavurage/meulage de nervures d'ailes d'avion ou d'objets similaires.
