Abstract

La présente invention se rapporte à une unité d'estampage et de poinçonnage ayant une partie principale en forme de U (1), dont la partie extérieure de l'un des bras (1a) est pourvue d'un évidement destiné à recevoir une matrice (3) et dont la partie extérieure de l'autre bras (1b) est pourvue d'un trou ou d'un passage destiné à guider un porte-poinçon (5') avec son poinçon (6). Dans ladite unité, une plaque supérieure (7) placée sur le porte-poinçon (5) est destinée à tenir le porte-poinçon (5) à distance de la matrice au moyen d'un dispositif à ressort, de sorte qu'une pièce à usiner puisse être introduite dans un espace (10) défini entre le poinçon et la matrice. Le dispositif à ressort (8) est enfermé dans un élément cylindrique creux en plastique (11). Les dimensions intérieures de l'élément cylindrique creux (11) coïncident, au moins sensiblement, avec les dimensions extérieures des ressorts à disques ou ressorts Belleville (8). Le matériau dans lequel est fabriqué l'élément cylindrique creux (11) présente des caractéristiques élastique. L'élément (11) forme une protection autour des rondelles coniques et peut servir d'organe à ressort complémentaire.
