Abstract
Balancier à friction à contre-frappe améliorant les conditions du travail d'estampage des pièces métalliques. Il consiste en un bâti supportant une vis-écrou 1, comportant des filetages à pas contraires, actionnée par un dispositif d'inversion approprié. La partie formant écrou 2, commande un coulisseau supérieur 8, la partie formant vis 3, commande un coulisseau inférieur 10, ceci par l'intermédiaire d'un écrou 9, auquel il est relié par des barres de liaison 11. La rotation dans un sens ou dans l'autre de la vis-écrou 1, éloigne ou rapproche les coulisseaux antagonistes 8 et 10, sur la face desquel sont disposées les demi-matrices 12 et 13, destinées à effectuer le travail d'estampage. L'invention perfectionne le fonctionnement et améliore le rendement des balanciers à friction conventionnels.
