Abstract

Outil pour des opérations comme le pliage ou la coupe et comportant un mécanisme d'actionnement (11, 12, 14, 20, 24, 25) mobile par rapport à un corps d'outil (13) auquel il est fixé de manière pivotante. Sont également prévus sur le corps de l'outil (13) un bloc poussoir (18) et un bloc butée (21) disposés de telle manière que, après actionnement du mécanisme d'actionnement (11, 12, 14, 20, 24, 25), se produit un mouvement relatif entre le bloc poussoir (18) et le bloc butée (21) d'une position de repos à une position d'opération. Dans la position de repos, le bloc butée (21) est situé par rapport au bloc poussoir (18) de telle manière qu'est intercalée entre eux une pièce à usiner allongée et qu'est effectuée une opération de pliage ou de coupe par l'interaction du bloc poussoir (18) et du bloc butée (21). Est également prévu un mécanisme de fixation libérable (33, 34, 36) pour le bloc poussoir (18) et/ou le bloc butée (21), grâce auquel des blocs poussoir (18) et/ou des blocs butée (21) de divers types peuvent être fixés au corps de l'outil (13) en fonction de besoins d'une opération de pliage ou de coupe particulière.
