This utility model belongs to the field of winding technology, and particularly relates to a coil shaping mechanism, including a mounting base, a connecting block, a driving component, a fixed support component, and a movable support component. The fixed support component is disposed at one end of the mounting base, and a sliding guide rail is provided on one side of the mounting base. The connecting block is slidably disposed on the sliding guide rail, and the movable support component is disposed at one end of the connecting block. The driving component is disposed on the mounting base and connected to the connecting block. The driving component drives the connecting block to slide along the sliding guide rail, thereby driving the movable support component to move closer to or away from the fixed support component. The fixed support component and the movable support component are used to extend into the inner coil of the coil. The movable support component moves closer to or away from the fixed support component as the connecting block moves. During overall operation, the coil is placed on the fixed support component and the movable support component, which extend into the inner coil of the coil. At this time, the driving component drives the movable support component to move, thereby achieving the shaping and correction of the coil.
