发明名称 LAMINATED CORE AND ITS MANUFACTURING METHOD
摘要 PROBLEM TO BE SOLVED: To facilitate and secure skew rotation by improving a caulking coupling means for temporarily fixing each core plate and also to simplify and efficientize the structure and process of a regular-succession molding device which die-cuts each core plate and stacks core plates in alignment (vertical lamination). SOLUTION: As the caulking coupling means 6 which laminates and couples, in aligned stacking state, each core plate 2 provided, at its periphery, with engaging parts 5 and enables skew rotation after winding, this laminated core 1 is provided with a circular caulking part 7 which is capable of sliding rotation in its circumferential direction and perforations 8 and 9 which secure skew regions at one end or both ends of the caulking part 7. The caulking part 7 is made of a half-perforated caulking recess 7a and a caulking projection 7b. The caulking projection 7b of one core plate 2 out of two core plates adjoining each other above and below engages with the caulking recess 7a of the other core plate 2, and they are caulked and coupled via an interference 10 provided either on the side of the internal diameter of the caulking part 7 or on the side of its external diameter.
