METHOD FOR LAMINATING IRON CORE AND LAMINATING STRUCTURE OF IRON CORE

摘要

PURPOSE: A method for laminating an iron core and a laminating structure of an iron core are provided to enhance the productivity by producing simultaneously an I-shaped iron core and an E-shaped iron core without loss of raw materials. CONSTITUTION: A couple of E-shaped iron cores(20e) are opposite to each other on an original plate. A couple of I-shaped iron cores(20i) are formed in an area formed by the E-shaped iron cores(20e). The E-shaped iron cores(20e) and the I-shaped iron cores(20i) are pressed simultaneously. A plurality of combination grooves(24) are formed at each end portion of opening parts of the E-shaped iron cores(20e). A plurality of combination projections(22) are formed at positions corresponding to the combination grooves(24). The combination projections(22) are inserted into the combination grooves(24).
