APPARATUS FOR MANUFACTURING LAMINATED IRON CORE

摘要

PROBLEM TO BE SOLVED: To efficiently suppress unnecessary heat transfer from a heating means to its surrounding members without complicating the constitution of a die even when the heating means for hardening an adhesive is provided in an apparatus for manufacturing a laminated iron core. SOLUTION: The apparatus 11 for manufacturing the laminated iron core 1 is provided with: an adhesive-applying device 21 for applying the adhesive to an iron core sheet 2 to be blanked; a squeeze ring 31 in the inside of which blanked iron core sheets are laminated; a heater 32 which is annexed to the a squeeze ring and with which the adhesive is heated and hardened; and a vacuum heat insulating body 33 which has a vacuum layer V in its inside so as to cover the periphery of the heating heater.
