At present, a plurality of high-frequency induction heating local annealing modes are used for local softening, and the screw holes and the annular columns where the screw holes are positioned are softened by induction heating and conduction of the annular heating rings sleeved around the screw holes on the outer surface of the workpiece, so that the aim of reducing hardness is fulfilled.
