Title:
METHOD FOR MANUFACTURING WIRE MATERIAL, DEVICE FOR MANUFACTURING WIRE MATERIAL, WIRE MATERIAL, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/064713
Kind Code:
A1
Abstract:
This method for manufacturing a wire material 11 for forming a coil 10 includes: a step for arranging an element wire 11A in a molding space surrounded by a plurality of split molds; and a step for moving the molding space in a clamping direction and pressure-molding the element wire 11A. In the step for pressure-molding the element wire 11A, at least one of the plurality of split molds is moved, and the split molds each have a surface that changes in the longitudinal direction of the element wire, and pressure-mold the element wire 11A into the wire material 11 which has a plurality of different cross-sectional shapes in the longitudinal direction.
