Abstract

Official abstract text for this publication.

A bending-forming jig used in bending and forming a protruding portion of a leg portion of a U-shaped conductor toward a circumferential direction, the protruding portion protruding from an axial end surface of a stator core, the bending-forming jig including a ring portion and a claw portion, the claw portion including a first abutting surface that rises from an axial end surface of the ring portion with the surface directed in the circumferential direction and abuts against a tip portion of the protruding portion from the circumferential direction, and a projecting portion that projects, at a tip end of the claw portion, in the circumferential direction from the abutting surface and abuts against the tip portion of the protruding portion from the axial direction toward the axial end surface of the ring portion.

First claim

Opening claim text (preview).

The invention claimed is: 1. A bending-forming jig configured to bend and form a protruding portion of a leg portion of a U-shaped conductor in a circumferential direction, the U-shaped conductor inserted in slots of a stator core, the protruding portion protruding from an axial end surface of the stator core, the bending-forming jig comprising: an annular ring portion; and a claw portion that protrudes in the axial direction from an axial end surface of the ring portion, wherein the claw portion comprises a first abutting surface directed in the circumferential direction that rises in the axial direction from the axial end surface of the ring portion and is configured to abut against a tip portion of the protruding portion from the circumferential direction when the protruding portion is bent and formed, and a projecting portion that projects, at a tip end of the claw portion, in the circumferential direction from the first abutting surface and is configured to abut against the tip portion of the protruding portion from the axial direction toward the axial end surface of the ring portion when the protruding portion is bent and formed. 2. The bending-forming jig according to claim 1 , wherein the claw portion further comprises a second abutting surface disposed on an opposite side of the first abutting surface, in the circumferential direction, and which is configured to abut against the tip portion of the protruding portion from the circumferential direction when the protruding portion is bent and formed. 3. The bending-forming jig according to claim 1 , wherein the first abutting surface is inclined in the circumferential direction. 4. The bending-forming jig according to claim 1 , wherein the first abutting surface rises perpendicularly in the axial direction from the axial end surface of the ring portion.
