DIE DEVICE FOR MANUFACTURING LAMINATED CORE

摘要

PROBLEM TO BE SOLVED: To provide a die device for manufacturing a laminated core in which the product accuracy is secured while meeting the high punching speed by a simple and inexpensive means by slightly improving a conventional structure, and which contributes to improve the productivity to reduce the cost of the laminated core product. SOLUTION: In the die device for manufacturing the laminated core 14 in which each core sheet 13 punched and dropped in rotary die parts 6 and 7 is rotatably laminated while rotating the rotary die parts 6 and 7, and the core sheets of the predetermined number are fixed in a laminated condition by a caulking means provided on each core sheet, a step 19 for stopping the core sheet 13 is formed on a part of inner circumferential surfaces of the rotary die parts 6 and 7.
