Abstract

PURPOSE:To eliminate the damage of a winding coat by causing no blanking burrs projecting to the outside to be formed through blanking the inside and outside of a profile respectively, when steel plates positioned at the lower and upper ends of a laminated core are blanked. CONSTITUTION:The manufacturing apparatus of a laminated core is equipped with a pressing machine having processing stages from the first stage A to the fifth stage E. In the third stage C, a blanking steel plate positioned at the upper end in the laminating direction of the laminated core is blanked by a blanking punch body 8c. The outside of a profile of the part to be wound by a winding is blanked at the time of said winding. In the fifth stage E, a blanking steel plate positioned at the lower end in the laminating direction of the laminated core is blanked by a blanking punch body 8e. The inside of said profile is blanked at the time of this blanking.
