Claims

[Scope of utility model registration request]

In a steel plate punching and spinning die that simultaneously punches the iron core plate of an electric motor and simultaneously engages and spins the cut parts provided on the iron core plate, a holder having a through hole with a step in the center and the step part are used. A disk-shaped lateral pressure guiling having an inner diameter smaller than the diameter of the through hole and a punching plate outer diameter die are arranged with the former facing down, and are in contact with the bottom of the stepped portion in the shape of a rectangular parallelepiped and have a rectangular pyramid shape inside. A plurality of cam slides are arranged, a plurality of cylinders that slide in the penetrating direction of the through hole are arranged in the circumferential direction on the inner circumference, and cams each having a rectangular pyramid-shaped tip are fixed to the shaft end of the cylinder shaft, As the cam slides in the penetration direction, the rectangular pyramid shape of the cam tip and the rectangular pyramid shape of the cam slide fit together, and the cam slide slides in the through hole in the radial direction q, causing the tip of the cam slide to protrude from the inner periphery of the through hole. , the plurality of bent portions of the laminated core punches held by the lateral pressure guiling are held at the tip of the cam slide, and the core punches are sped up by the pressing force of the press machine to form the core, and the cam slide Move the tip of the core to the same level as the inner periphery of the through hole, punch out and bundle the core blanks for the next core from above the core, eject the first core from the extrusion mold, and then cam slide again. An iron plate punching binding mold made by repeatedly protruding the tip of the tip to the inner periphery of a through hole and repeating the above operation.
