Title:
COIL FORMING DEVICE AND COIL FORMING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/097865
Kind Code:
A1
Abstract:
A plurality of housing grooves (11a) are formed in an outer circumferential edge of a circular block (11) at equal intervals in a circumferential direction, and inside rods (13) are housed in these housing grooves (11a) and disposed radially and movably in a radial direction. Outside rods (33) are disposed radially and movably in the radial direction so as to face the respective inside rods (13). One slot insertion portion (18a) of a coil segment (18) is inserted into a gap (39) between the inside rods (13) and passed through an insertion hole (19c) of a holding member (19), and the other slot insertion portion (18b) is inserted into a gap (41) between the outside rods (33). Thereafter, the entire outside rods (33) are rotated to cause the coil segment (18) to move rotationally about the slot insertion portion (18a), the holding member (19) is lowered at a timing when the slot insertion portion (18b) makes contact with an outer circumferential surface of the holding member (19), and the entire outside rods (33) are further rotated in a state in which the slot insertion portion (18b) and the holding member (19) do not interfere with each other, thereby closely attaching the coil segment. This configuration improves the efficiency of coil assembly work.
