LAMINATION BARREL HAVING GUIDE GROOVE OR GUIDE PROTRUDE PART AND, APPARATUS FOR MANUFACTURING LAMINAE STACK HAVING THE LAMINATION BARREL

摘要

PURPOSE: A laminate barrel with a guide groove or guide protrusion part and a laminate core manufacturing apparatus including the same are provided to combine a laminar member of a top layer with a laminar member of a bottom layer at a right position by preventing the laminar members from arbitrarily rotating. CONSTITUTION: A blank die(172) includes a hollow part into which a blanking punch is inserted and a guide groove(176). The guide groove is downwardly formed from the upper side of the blank die in a vertical direction. A metal strip is blanked and is formed on the laminar member. The guide protrusion part is downwardly formed from the upper side of the blank die on an inner surface(175) of the blank die. Both ends of the guide protrusion part overlap a wing part of the laminar member.
