Abstract

L'invention concerne une presse radiale pourvue d'une structure de base, d'un outil de compression logé dans ladite presse et d'une unité d'entraînement. L'outil de compression comprend huit mâchoires de base (1) qui sont disposées autour d'un axe de compression (6) et qui, pour fermer ou ouvrir l'outil de compression, peuvent être approchées ou éloignées de l'axe de compression (6) au moyen de l'unité d'entraînement de manière synchrone et radiale à l'axe de compression (6), une tête de mâchoire de compression (2) présentant une surface de compression (9) pouvant être montée de manière interchangeable au niveau de chaque mâchoire de base. Selon l'invention, sur les huit mâchoires de base (1) sont montées au moins quatre têtes de mâchoire de compression (2) qui, lorsque l'outil de compression est fermé au maximum, forment autour de l'axe de compression (6) un espace creux (7) limité par six surfaces de mise en forme (8) planes sous forme d'un prisme régulier à six côtés.
