Abstract
A coil bending machine is a machine that, in a stator core including a yoke and multiple teeth and having a slot formed between circumferentially adjacent teeth, while lead portions of a segment coil which is a U-shaped lead wire including a bent portion K and two lead portions R extending from the bent portion are inserted into two slots, push-bends end portions of the lead portions protruding from an axial end face of the stator core toward the stator core. The coil bending machine includes a coil bending member that push-bends the end portions of the lead portions protruding from the axial end face of the stator core toward the stator core, and a coil pressing mechanism that press-fixes a segment coil inside the slot toward the yoke, from the radially inner side of the stator core.
