Abstract

Ensemble poinçon-matrice permettant de remplacer facilement le poinçon, la matrice ou autre élément similaire et d'améliorer la précision du travail. Dans cet ensemble poinçon-matrice, un dévêtisseur monté de façon qu'il puisse coulisser verticalement sur la surface périphérique intérieure d'un manchon creux (5) fermement assujetti à un porte-ensemble (4) par l'intermédiaire d'un élément de liaison comprend un corps creux de dévêtisseur (6) et une plaquette de dévêtisseur (7) pourvue d'un trou (8) de passage du poinçon et constituant le fond amovible du corps de dévêtisseur (6). Une matrice (2) est montée amovible sur un porte-matrice (20) fixé fermement sur le porte-ensemble (4) par l'intermédiaire d'un élément de liaison. Des moyens de positionnement sont prévus, respectivement entre le corps de dévêtisseur (6) et la plaquette de dévêtisseur (7) et entre la matrice (2) et le porte-matrice (20).
