    • PROBLEM TO BE SOLVED: To enable one-time bending even for a quadrupolar machine in manufacturing a coil of a rotary electric machine.SOLUTION: The coil manufacturing system comprises an edgewise bending device 18, a flatwise bending device 19, a cutting device 21 and a cut surface finishing device 105. The edgewise bending device 18 performs edgewise bending of laminated conductors at the end portion in a lateral-width direction in a lump. The flatwise bending device 19 performs flatwise bending of the laminated conductors at the edgewise bent end portion in the direction of laminating. The cutting device 21 cuts the flatwise bent end portion to a predetermined length. The cut surface finishing device 105 finishes the cut surface of the laminated conductor at the cut end portion. The edgewise bending device 18 may have an edgewise bent coil restraint mechanism which prevents the displacement of a conductor during forming by restraining the linear portion and the end portion in their lateral-width directions and thickness directions.
    • 要解决的问题:即使在制造旋转电机的线圈的四极机时也能够一次性弯曲。解决方案:线圈制造系统包括沿边弯曲装置18,平面弯曲装置19,切割装置21和 切边表面处理装置105.沿边弯曲装置18沿横向宽度方向的端部进行层叠导体的沿边弯曲。 平面弯曲装置19在层叠方向上沿边缘弯曲端部进行层压导体的平面弯曲。 切割装置21将平坦的弯曲端部切割成预定长度。 切割表面处理装置105在切割端部处完成层压导体的切割面。 沿边弯曲装置18可以具有沿边弯曲的线圈限制机构,其通过在直线部分和端部部分的横向宽度方向和厚度方向上的限制来防止导体在成形期间的位移。
