PROBLEM TO BE SOLVED: To eliminate a galling at the time of insertion to a molding die by making a cutting plane of a bar shaped material flat, and to minimize a temperature drop of the bar-shaped material, and to secure the heating range of the bar-shaped material sufficiently, regarding a forging device. SOLUTION: A cutting and a transport means are separately independent cutting mechanisms and transport mechanisms. By providing a blade of a cutter installed in the cutting mechanism over a circumferential direction, a cut surface of the bar-shaped material W is made flat, and a galling at the time of insertion to a molding die of the bar-shaped material W is eliminated. A heating element 3 is arranged in order to heat a practical length of the cutting range of the bar-shaped material. A temperature drop of the bar-shaped material W is controlled, a screw head is formed efficiently, and a throughput of the forming process is improved. COPYRIGHT: (C)2003,JPO
