METHOD AND DEVICE FOR MANUFACTURING ELECTRIC APPARATUS COIL

WIPO Patent Application WO/2019/235309

A1

According to this method for manufacturing an electric apparatus coil, a block-shaped material to be processed that has formed a tubular portion corresponding to a coil is cut spirally in the circumferential direction of the tubular portion. The method for manufacturing an electric apparatus coil comprises forming a spiral coil by turning a cutting means around the material to be processed, while causing the cutting means to be moved relative thereto from a portion corresponding to one end side of the coil toward a portion corresponding to the other end side thereof along a processing line set spirally in the circumferential direction of the tubular portion. According to the present invention, the coil is formed by cutting, using a wire tool or the like, continuous cutting-process surfaces having no steps in design from the block-shaped material to be processed having formed the tubular portion corresponding to the coil. Thus, it is possible to configure a high-quality coil.
