  9. Procédé de remplacement d'un emporte-pièce (A), lequel est utilisé sur le centre de découpe et d'usinage intelligent à haute vitesse selon la revendication 4 et comprend les étapes suivantes :
    dans l'étape 1, la tête de découpe rotative (8) est déplacée à partir d'une région de travail au milieu de la table de travail (4) pour se retrouver au-dessus de la table de déplacement d'emporte-pièces (3) ; les composants de limitation mobiles (97) du dispositif de limitation et de serrage d'emporte-pièces (9) sont déplacés à proximité du chargeur d'emporte-pièces (2) ; la tête de découpe rotative (8) entraîne l'emporte-pièce (A) en descente vers une position permettant le remplacement de l'emporte-pièce (A) ; les cylindres de pression (96) entraînent la plaque de pression d'emporte-pièces de gauche (94) et la plaque de pression d'emporte-pièces de droite (95) en déplacement vers le bas respectivement pour permettre aux composants de limitation mobiles (97) de se trouver dans un état déverrouillé par liaison ; l'ensemble de serrage (91) est dans un état relâché, et l'ancien emporte-pièce (A1) attend d'être remplacé ;
    dans l'étape 2, le cylindre de poussée primaire (33) entraîne le cylindre de poussée secondaire (38) et la plaque à crochet (39) en déplacement à partir d'une position initiale vers la tête de découpe rotative (8) ; simultanément, le cylindre de poussée secondaire (38) entraîne également la plaque à crochet (39) vers la tête de découpe rotative (8) jusqu'à ce que la plaque à crochet (39) se trouve sous un ancien emporte-pièce (A1) à remplacer ; deux cylindres de levage (36) entraînent le cylindre de poussée secondaire (38) et la plaque à crochet (39) en déplacement vers le haut à travers la plaque de connexion de cylindre (37) simultanément jusqu'à l'insertion du crochet de traction (310) de la plaque à crochet (39) vers le haut dans le trou de crochet (C) de l'ancien emporte-pièce (A1) ;
    dans l'étape 3, le cylindre de poussée secondaire (38) et le cylindre de poussée primaire (33) se déplacent simultanément vers le chargeur d'emporte-pièces (2) ; l'ancien emporte-pièce (A1) est retiré du dispositif de limitation et de serrage d'emporte-pièces (9) dans un état relâché dans l'étape 1 et déplacé vers une position définie dans le chargeur d'emporte-pièces (2) ; ensuite, deux cylindres de levage (36) entraînent la plaque à crochet (39) en déplacement vers le bas et puis le cylindre de poussée secondaire (38) recule pour permettre à la plaque à crochet (39) de quitter le chargeur d'emporte-pièces (2) ;
    dans l'étape 4, le dispositif de levage (23) dans le chargeur d'emporte-pièces (2) agit pour déplacer un nouvel emporte-pièce (A2) vers une position propre ; le cylindre de poussée secondaire (38) se déplace à nouveau vers le chargeur d'emporte-pièces (2), et les deux cylindres de levage (36) relèvent à nouveau la plaque à crochet (39) jusqu'à l'insertion du crochet de traction (310) de la plaque à crochet (39) vers le haut dans le trou de crochet (C) du nouvel emporte-pièce (A2) ;
    dans l'étape 5, le cylindre de poussée primaire (33) entraîne le cylindre de poussée secondaire (38) et la plaque à crochet (39) vers la tête de découpe rotative (8) ; simultanément, le cylindre de poussée secondaire (38) entraîne également la plaque à crochet (39) vers la tête de découpe rotative (8) jusqu'à ce que la plaque à crochet (39) déplace le nouvel emporte-pièce (A2) dans le dispositif de limitation et de serrage d'emporte-pièces (9) dans un état relâché ; le nouvel emporte-pièce (A2) est arrêté par le composant de limitation fixe de l'autre côté, et l'ensemble de serrage (91) agit inversement pour serrer le nouvel emporte-pièce (A2) ; les cylindres de pression (96) entraînent la plaque de pression d'emporte-pièces de gauche (94) et la plaque de pression d'emporte-pièces de droite (95) en déplacement vers le haut pour permettre aux composants de limitation mobiles (97) de se trouver dans un état de limitation par liaison ; ainsi, le nouvel emporte-pièce (A2) est serré et limité ; ensuite, deux cylindres de levage (36) entraînent la plaque à crochet (39) en déplacement vers le bas, et puis le cylindre de poussée primaire (33) et le cylindre de poussée secondaire (38) reculent vers leurs positions initiales ; la tête de découpe rotative (8) est relevée et renvoyée vers la région de travail au milieu de la table de travail (4), achevant ainsi le cycle de remplacement de l'emporte-pièce (A).
