Abstract

L'invention concerne une machine de déformation orbitale comprenant un bâti (20) sur lequel une broche primaire (21) est entraînée en rotation autour d'un axe (Z0), et une broche secondaire (22) portant un outil (23) de déformation, ladite broche secondaire étant liée à ladite broche primaire en rotation libre autour d'un axe (Z1) de sorte que ledit outil soit entraîné en rotulage lors de la rotation de ladite broche primaire, la broche secondaire (22) étant liée au bâti par un dispositif comprenant un moyen d'attache (24) présentant une première extrémité (24a) associée à ladite broche secondaire et une deuxième extrémité (24b) associée audit bâti, ledit moyen d'attache étant maintenu en tension par un moyen élastique (25) qui est agencé pour contraindre la rotation de ladite broche secondaire autour de l'axe (Z1) en l'absence d'effort de déformation appliqué par l'outil (23).The invention relates to an orbital deformation machine comprising a frame (20) on which a primary spindle (21) is rotated about an axis (Z0), and a secondary spindle (22) carrying a tool (23) deformation, said secondary spindle being linked to said primary spindle in free rotation about an axis (Z1) so that said tool is rotated during the rotation of said primary spindle, the secondary spindle (22) being linked to the frame by a device comprising a fastening means (24) having a first end (24a) associated with said secondary spindle and a second end (24b) associated with said frame, said fastening means being held in tension by elastic means (25 ) which is arranged to constrain the rotation of said secondary spindle around the axis (Z1) in the absence of deformation force applied by the tool (23).
