[0002] The hairpin is a hard wire in a generally U-shaped form, and when a motor of a new energy automobile is manufactured, the hairpin needs to be evenly inserted on a cylindrical stator core. After the insertion of the hairpin is completed, the hairpin is in a radial and spiral distribution in the orthographic projection of the stator core, the end portion of the hairpin forms a plurality of concentric circles distributed on the stator core, and the hairpin is closely arranged. After the hairpin is inserted and fixed on the stator core, the opening formed at the end portion of the hairpin needs to be flared for the convenience of subsequent processing.

[0003] At present, a coil flaring device is disclosed in Chinese Patent No. CN219541508U, which comprises a mounting frame, the mounting frame comprises three layers of mounting plates arranged horizontally and at intervals, a plurality of connecting columns are arranged between the mounting plates, and a through hole is formed in the middle portion of each mounting plate. A pushing mechanism for pushing the stator core with the inserted hairpin is installed on the bottom mounting plate, a centering locking mechanism for positioning and clamping the stator core is installed on the middle mounting plate, and a flaring mechanism is installed on the top mounting plate.
