The present invention is to provide a forging method capable of transferring a workpiece with a high degree of positional accuracy. The present invention is directed to a forging method in which a workpiece (W) disposed at a workpiece introducing section (50) is sandwiched and held from both sides of the workpiece with a pair of claws (42) provided to a pair of feed bars (41) arranged on both sides of a transferring line by closing the feed bars (41), and transferred to a workpiece processing section by opening the feed bars (41) after moving the feed bars (41) forward to the workpiece processing section with the workpiece (W) sandwiched and held, and the workpiece (W) transferred to the workpiece processing section is forged. In the method, the workpiece (W) is previously provided with an engaging portion (85) and the claw (42) is previously provided with an engaging portion receiving portion (45) so that the workpiece (W) is positioned by engaging the engaging portion (85) with the engaging portion receiving portion (45) at the time of sandwiching and holding the workpiece (W) with the claws (42). |
