Abstract

L'invention concerne une pince à sertir (1) pourvue de mors de sertissage (10). Les mors de sertissage (10), pour former une zone sertie au moyen des zones d'extrémité associées des poinçons de sertissage, sont montés de manière à pouvoir tourner autour d'un axe de rotation (11) pour rentrer par pivotement dans une position finale de sertissage. Les mors de sertissage (10) présentent en outre respectivement une surface d'action (13) formant une partie de la zone de sertissage. La surface d'action (13) est formée en s'étendant de manière convexe dans un plan du mors de sertissage (10), dans lequel l'axe de rotation (11) est tracé par points, et termine côté zone de sertissage dans une pointe de mors (12). La pointe (12a) d'un premier mors de sertissage (10a) se déplace, au cours du pivotement rentrant le long de la surface d'action convexe (13) d'un second mors de sertissage (10b) adjacent pivotant de manière simultanée, en direction de la pointe (12b) de ce second mors de sertissage (10b). L'objet de l'invention est de réaliser de façon peu onéreuse, sur un mors de sertissage, une pince de sertissage présentant une surface d'action s'étendant de manière convexe. A cet effet, la surface d'action (13) est formée par une pluralité de nervures (14), lesquelles s'étendent à partir d'une surface de base d'action (16) et transversalement à l'axe de rotation (11).
