The method is to mainly form an intermediate shaped part 1C between the columnar part 7 and the shaft part 1A on a material having a substantially spherical part at the shaft end, and in some cases compression mold the substantially spherical part into a roughly cylindrical part having both upper and lower end surfaces. After molding, the closing mold holds both ends of the cylindrical part in the correct position by holding down the shaft, and the cushioning force that creates a closing force in the upper and lower molds can be adjusted separately for the upper and lower molds. ! In order to do this, the first punch for forming the first hole on the bottom and the second punch for forming the side hole may be operated simultaneously or in either case depending on the shape of the workpiece. The press is characterized in that the hole and outer shape are formed in one stroke of the press by sequentially operating the force and force.
