Title (EN) DIE HEAD
(FR) TETE DE DECOLLETEUSE
Abstract:
(EN) A fast-acting die head (10) that is particularly well-suited for use with small-size workpieces employs a set of chasers (24), each formed as a single piece (24) and having a nose portion (36) that provides two force-receiving surface elements (35, 38). One of the surface elements (35) is disposed to coact with a camming ring (48), which is moved axially thereover to close the chasers (24) radially upon the workpiece; the other, underlying surface element (38) receives the force of a spring-loaded plunger (40), which acts to thrust the associated chaser (24) to an open position when the closing force of the camming ring (48) is removed.
(FR) L'invention porte sur tête de décolleteuse (10) particulièrement adaptée aux pièces à usiner de petit calibre comportant un jeu de peignes (24) d'une seule pièce dont le nez (36) comporte deux surfaces d'application de forces (35, 38). L'une de ces surfaces (35) est conçue pour coopérer avec une came annulaire (48) qui en s'y déplaçant axialement referme les peignes (24) radialement sur la pièce; l'autre surface (38), sous-jacente, est soumise à la force d'un piston (40), chargé par un ressort, qui pousse le peigne associé en position d'ouverture quand la force appliquée par la came annulaire (48) cesse.
