Abstract

La présente invention concerne une machine de forgeage par laminage qui comprend une paire de matrices à rouleaux (4 et 6) qui sont disposées sur une paire d'essieux d'entraînement de rouleau (3 et 5) mis en rotation par un dispositif de commande et comportent une pluralité de matrices de mise en forme (4a1 à 4a4 ; 6a1 à 6a4) formées sur ces dernières respectivement, et des unités de transport destinées à transporter des matériaux qui doivent être mis en forme à une position de mise en forme avec les matrices, jusqu'à une position de réception et jusqu'à une position de mise en œuvre. Les unités de transport comprennent un premier robot (10) qui comporte une main de robot (25) qui se déplace le long d'un premier trajet rectangulaire pour un mouvement (50A) comprenant un trajet en ligne droite pour un mouvement de mise en forme (51) reliant les positions correspondant aux positions de mise en forme avec la pluralité de matrices de mise en forme et un premier trajet pour s'écarter (52) sur un côté d'une distance prédéterminée (L1) du trajet en ligne droite pour un mouvement de mise en forme (51), et un second robot (30) qui comporte une main de robot (45) qui se déplace le long d'un second trajet rectangulaire pour un mouvement (50B) comprenant le trajet en ligne droite pour un mouvement de mise en forme (51) et un second trajet pour s'écarter (53) sur l'autre côté d'une distance prédéterminée (L2) du trajet en ligne droite pour un mouvement de mise en forme (51). Une machine de forgeage par laminage et un procédé de forgeage par laminage sont obtenus selon lesquels les matériaux qui doivent être mis en forme sont transmis en alternance à une paire de matrices à rouleaux comportant deux unités de transport et une mise en forme avec des matrices est réalisée successivement.
