Abstract

L'invention porte sur une poinçonneuse comportant: des têtes de poinçonnage (22) montées sur l'embase (21) de l'unité de poinçonnage (7); des vérins pneumatiques (24) s'élevant pour passer de la position de poinçonnage à la position d'attente; des bielles de transmission (36) des marteaux, engagées dans les têtes de poinçonnage (22); des poinçons fixés à l'extrémité inférieure des bielles de transmission (36) et pouvant s'extraire du côté de la matrice (12); des coiffes (39) empêchant le soulèvement de la pièce placées à l'extrémité des têtes de poinçonnage (22) et s'écartant de la matrice (12) de manière à laisser un petit espace entre les coiffes (39) et la matrice (12) pour le transfert de la pièce lors de l'usinage. Pour remplacer les poinçons, l'unité de poinçonnage (7) est soulevée par un vérin pneumatique (17), ce qui permet de démonter les coiffes (39) et de changer les poinçons. Le remplacement des poinçons est ainsi facile et rapide sans qu'il faille démonter les têtes de poinçonnage.
