  • Laminated core punching apparatus
    Patent number: 8720039
    Abstract: A laminated core punching apparatus, configured such that a stator-punching press machine that has a molding die performing a partial punching gradually approaches the shape of the stator core piece. There is a punching die to punching out the stator core piece from a strip-form steel plate, and two stator lamination stations. A rotor-punching press machine and a stator-punching press machine are constructed to operate synchronously. An intermediate loop portion capable of causing a strip-form steel plate to hang down in a loop is provided in order to adjust a length of the strip-form steel plate between the two press machines, and a loop guide portion that guides a loop locus of the strip-form steel plate from above so that the strip-form steel plate does not invert is disposed above the intermediate loop portion to be capable of ascending and descending.
