  • Patent number: 11786951
    Abstract: The manufacturing apparatus for a metal component includes: a preheating portion configured to locally induction-heat a metal plate; and a stamping portion configured to stamp the metal plate. The preheating portion includes a heating coil. The heating coil is arranged such that an axial direction of the heating coil is along a movement direction of the pressing portion and the heating coil faces, in the axial direction, an area where an amount of deformation is relatively large in a processing region of the metal plate to be stamped by the stamping portion. The heating coil is configured such that at least a part of the area where the amount of deformation is relatively large in the processing region of the metal plate is heated to a higher temperature than an area where the amount of deformation is relatively small in the processing region.
