Zusammenfassung:A heat sealing-type rotational laminated core manufacturing apparatus enabling the automatic separation of a laminated core, according to the present invention, is a laminated core manufacturing apparatus comprising an upper mold (3) and a lower mold (4) and forming and stacking individual laminar members (101), the individual laminar members (101) being formed by having a strip (100A) which is sequentially transferred on an upper portion of the lower mold (4) undergo a piercing process and a blanking process by means of punches provided to the upper mold (3), wherein the heat sealing-type rotational laminated core manufacturing apparatus enabling the automatic separation of a laminated core comprises: a squeeze ring (201) installed on a lower portion of a blanking die (11) for the blanking process; a heating means (202) installed on an outer portion of the squeeze ring (201); a rotating die (203) having the squeeze ring (201) and the heating means (202) installed therein so as to rotate by a predetermined pitch with the squeeze ring (201) and the heating means (202); a vertically-moving die installed on one side of the blanking die (11) and having a plurality of protruding portions (32') and recessed portions (32A) provided thereto; and a fixed die (31) installed on the upper mold (3) on an upper side of the vertically-moving die (31) and having a plurality of recessed portions (31') and protruding portions (31A) provided thereto. L'invention concerne un appareil de fabrication de noyau feuilleté rotatif de type à thermoscellage permettant la séparation automatique d'un noyau feuilleté comprenant un moule supérieur (3) et un moule inférieur (4) et formant et empilant des éléments laminaires individuels (101), les éléments laminaires individuels (101) étant formés d'une bande (100A) qui est transférée de manière séquentielle sur une partie supérieure du moule inférieur (4) et subissant un processus de perçage et un processus de poinçonnage au moyen de poinçons disposés sur le moule supérieur (3). L'appareil de fabrication de noyau feuilleté rotatif de type à thermoscellage permettant la séparation automatique d'un noyau feuilleté comprend : une bague de serrage (201) installée sur une partie inférieure d'une matrice de poinçonnage (11) pour le processus de poinçonnage ; un moyen de chauffage (202) installé sur une partie externe de la bague de serrage (201) ; une matrice rotative (203) comportant la bague de serrage (201) et le moyen de chauffage (202) ins
