Abstract

Afin que soit évité l'arrachement vers le haut de pièces ou de fragments de déchet lorsque le poinçon est soulevé à l'extérieur de l'outil de coupe de presses automatiques à estamper ou de presses à poinçonner à excentrique à nombre de courses élevé, les passages que présentent les matrices sont munis chacun de deux affutages en oblique opposés l'un à l'autre.In order to avoid upward pulling of pieces or fragments of waste when the punch is lifted outside the cutting tool of automatic stamping presses or punch presses with eccentric with high number of strokes, the passages presented by the matrices are each provided with two oblique sharpenings opposite one another.
