MANUFACTURING DEVICE FOR A MOTOR CORE

摘要

PURPOSE: A molding device for core production for motors is provided to improve out-of-roundness and cylindricity by forming all the areas of a stator and a rotor in equal thickness. CONSTITUTION: A die shoe forms the upper part of blanking mold. A die plate is installed on the upper side of the die shoe. A silicon steel plate is settled on the upper side of the die plate. A punch shoe(330) is installed on the upper side of the die plate. A stripper(340) is maintains the settlement of the silicone steel plate in the punching operation. A hole punching part(350) forms a shaft hole in the central part of the area of the core production of the silicone steel plate through the guidance of the stripper. A main punching part(360) severs the outer circumference of the core from the silicone steel plate through the guidance of the stripper. A plurality of secondary punching parts(401,402,403,404) form a positioning hole in the area of the production of the silicone steel plate's cores for rotors and stators.
