METHOD AND APPARATUS FOR MANUFACTURING LAMINATED CORE FOR MOTOR AND LAMINATING TOOL

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a laminated core for a motor and a laminating tool with which the break of an insulation coating is avoided and lamination is made possible by properly aligning and rotationally positioning laminating sheets (iron core sheets) without lowering manufacturing efficiency of the laminated core for the motor. SOLUTION: The laminating tool 34 which is located at a standby position T is arranged in the laminating position S shown by a chain line by being upward shifted. When the laminating tool 34 is arranged in the laminating position S, a second punch 23 for stator cores is vertically moved and the laminating sheets 26 for the stator cores are blanked from a metallic material. The blanked ring-shaped laminating sheets 26 for stator cores are caught with the laminating tool 34 in the state where the column 37 of the laminating tool 34 is fit into the middle hole 261 and positioning rods 39 are fit into the bolt inserting holes 262. The blanked laminating sheets 26 for the stator cores are laminated by moving in the blanking direction as they are and are successively fit into the laminating tool 34 and laminated.
