摘要： Provided are a manufacturing method for a blade material and a manufacturing device for a blade material, by which a long blade material can be manufactured without using a large-sized press forging machine. A manufacturing method for a blade material, in which hot forging is sequentially performed by molds from the root side to a blade (vane) tip, wherein when a root-side portion is grasped and a material to be forged is restrained by a mold, twisting is performed on a region between the grasped portion and the restrained portion. A manufacturing method for a blade material, in which hot forging and twisting are repeated, is preferable, and a manufacturing method for a blade material, in which hot forging is performed while molds are sequentially changed, is more preferable.

摘要翻译： 提供了一种用于刀片材料的制造方法和用于刀片材料的制造装置，通过该制造方法可以在不使用大型压力锻压机的情况下制造长刀片材料。 一种叶片材料的制造方法，其中通过模具从根侧到叶片（叶片）尖端依次进行热锻造，其中当抓握根部侧部分并且通过模具约束待锻造的材料时， 在夹持部和被约束部之间的区域进行扭转。 优选重复进行热锻加捻的刀片材料的制造方法，更优选在模具顺次变更时进行热锻的刀片材料的制造方法。
