Patent ID: 8912702

Claim:
A blanking mold for the production of a ferromagnetic core for electric motors formed by a plurality of separate segments, each segment consisting of a preset number of stacked laminations, comprising: a) at least one blanking station for blanking a plurality of laminations from a sheet of ferromagnetic material, at least part of said laminations comprising at least one protruding engagement portion and at least one concave engagement portion having mutually complementary shapes to allow engagement with the complementary engagement portions of adjacent laminations, b) at least one stacking station comprising an accumulation chamber for progressively stacking said laminations and for forming a plurality of segments of said ferromagnetic core, and c) at least one forming station for forming in said blanking mold a rectilinear sequence of adjacent segments by coupling the protruding engagement portions of the laminations of a segment with the concave engagement portions of the laminations of another adjacent segment.
