1. A method for manufacturing a sintered body by sizing a sintered body using a sizing apparatus comprising:
holding a die of a die plate of a die set, the die provided with a through hole to which a workpiece is to be supplied, and the die set including an upper punch and a lower punch that are inserted into the through hole to press the workpiece;
actuating the upper punch and the lower punch by a punch driving mechanism of a press main body, the die set being attachable to and detachable from a predetermined position in the press main body;
rotating a turntable having a plurality of housing holes on the die plate, the rotating of the turntable supplying a workpiece to the die and discharging a workpiece from the die, wherein the die plate includes a main body portion that holds the die, and a supporting base that is provided on the main body portion and on which the turntable is placed, the supporting base includes an axis positioning portion that is provided coaxially with a central axis of the turntable and positions the central axis at a predetermined position of the supporting base, and the die set includes the turntable, and is fixed to the press main body in a state in which the axis positioning portion positions the turntable relative to the die plate.
