Title (EN) SCREW-CUTTING LATHE WITH BAR SUPPLY
(FR) DECOLLETEUSE A ALIMENTATION DE BARRES
Abstract: front page image
(EN)Instead of a single poppet, two poppets (12A, 12B) are arranged longitudinally, of which the spindles (14A, 14B) have a common axis. The motions of these poppets in the direction of said axis as well as the opening and closing of the nippers are controlled so that one of the poppets provides the feeding of the bar (M) when its nipper is closed, whereas the other poppet returns to its start position, its nipper being open. During the transition phases, both nippers are closed. Hence, a separate bar supplying device is superfluous and the idole time necessary to the backward movement of the poppet is avoided.
(FR)A la place d"une seule poupee, on dispose longitudinalement deux poupees (12A, 12B) dont les broches (14A, 14B) ont un axe commun. Les mouvements des poupees dans la direction de cet axe ainsi que l"ouverture et la fermeture des pinces sont commandes de facon que l"une des poupees fasse avancer la barre (M) lorsque sa pince est fermee, tandis que l"autre revient dans sa position de depart, sa pince etant ouverte. Pendant les phases de transition les deux pinces sont fermees. Un dispositif separe d"alimentation en barres est ainsi rendu superflu et le temps mort necessaire au recul de la poupee est elimine.
