<P>PROBLEM TO BE SOLVED: To provide a method of molding a meandering annular coil capable of manufacturing a meandering coil satisfying the product dimension accuracy as a target with high yield. <P>SOLUTION: Press-in quantities (stroke quantities) of a diameter direction or an axial direction of a molding die for molding a meandering portion or a molding die for molding a non-meandering portion are each set for each of molding directions while considering spring-back quantities in each of molding directions in the meandering portion or the non-meandering portion when the meandering portion and the non-meandering portions are simultaneously molded. Specifically, for "an excessive press-in quantity for each molding direction of the molding die" to be added to a basic press-in quantity, the excessive press-in quantity of the molding die in a diameter direction is set to be larger than the excessive press-in quantity of the molding die in an excessive press-in quantity of the molding die in a depth direction in the meandering portion, and for the excessive press-in quantity of the molding die in the diameter direction, the excessive press-in quantity of the molding die of the meandering portion is set to be larger than the excessive press-in quantity of the molding die of the non-meandering portion. <P>COPYRIGHT: (C)2010,JPO&INPIT |
