Abstract

PURPOSE: To obtain the iron core having preferable magnetic properties of flange type having a flanged head at one end and a boss at the other end by conducting a cold drawing, an annealing and a finish drawing for a softer steel strand wire specified for its carbon content and other impurity contents when the flanged electromagnetic iron core is manufactured.
CONSTITUTION: When the flanged electromagnetic iron core having a flanged head at one end and a boss at the other end is manufactured, the softer steel strand wire containing approx. 0.01wt% or less of carbon content and 0.31wt% or less of other impurity contents is used as a material to be employed. That is, the stand wire 1' drawn and annealed is cut in a desired length, the cut wire is inserted into a die 22, a punch 23 is brought into contact with the end projected therefrom, the flanged head 3 is first formed, the head 3 is then grasped by the punch 23, is removed from the die 22, is then inserted into other die 22', and is urged. Thereafter, the drawn wire 1' thus urged is drawn through the die 22, and the iron core 1 having the head 3 and the boss 4 can be obtained.
