Abstract

La présente invention concerne une technique qui permet d'éliminer la morsure tout en empêchant une déformation d'une borne, même si une borne mord fortement dans un appareil de sertissage. La présente invention concerne un dispositif de sertissage de borne destiné à produire un fil équipé d'une borne par sertissage de la borne sur le fil. Le dispositif de sertissage de borne comporte : une enclume sur laquelle sont placés le fil et la borne ; un appareil de sertissage de fil destiné à sertir une gaine de fil de la borne sur une âme du fil ; un élément de butée ; et un élément de poussée. L'élément de butée vient en butée contre le fil équipé d'une borne dans un état dans lequel la borne mord dans l'appareil de sertissage tandis que le fil équipé d'une borne prend la même orientation de sertissage que pendant un sertissage. L'élément de poussée pousse l'élément de butée, venant en butée contre le fil équipé d'une borne qui prend l'orientation de sertissage, avec une force de poussée qui peut éliminer au moins une partie de la morsure de la borne.
