LAMINATED CORE MANUFACTURING APPARATUS CAPABLE OF HEATING INNER DIAMETER OF LAMINATED CORE

Disclosed is a laminated core manufacturing apparatus capable of heating the inner diameter of a laminated core. The present invention is a laminated core manufacturing apparatus comprising an upper mold (3) and a lower mold (4) and enabling the manufacturing of a laminated core (100) by stacking individual laminar members (101) which are formed by having a strip (100A) which is sequentially transferred on an upper portion of the lower mold (4) undergo a piercing process and a blanking process by means of punches provided to the upper mold (3), wherein the laminated core manufacturing apparatus further comprises: a squeeze ring (201) installed on a lower portion of a blanking die (11) for the blanking process; am elevating block (301) installed on the lower portion of the squeeze ring (201); an elevating means (302) for vertically moving the elevating block (301); and a heating block (304) installed on an upper portion of the elevating block (301) and positioned at an inner diameter surface of the laminated core (100).
