Abstract

PURPOSE: To rationalize manufacture by obtaining core pieces from a thin plate of a magnetic alloy by punching so that they will have flashes at proper positions of their outer circumferences, by stacking next pieces on previously-punched pieces by pressing, and by extracting and thermally processing laminations of fixed thickness.
CONSTITUTION: For example, when die 1 is so designed that core piece 5 will have flashes at proper positions (a) of its outer circumference and thin plate 4 of a magnetic alloy is punched by lowering punch 3, core piece 5 obtained by punching is hooked at the lower part of straight part 2 of die 1. When the next piece is made by punching, the new piece is pressed against the piece hooked at straight part 2 by the surplus strength of the punch to push them down by one. At this time, the flashes of the preceding piece intrude into those of the following piece, so that the both will couple with each other. In this way, when the lamination of pieces 5 reaches over table 7, separator 6 is moved so as to separate cores of fixed thickness. Then, the extracted lamination is thermally processed to fuse flash parts, to that their coupling will be made harder.
