摘要： PROBLEM TO BE SOLVED: To form a workpiece into a desired shape without causing damage to a die when the workpiece having a cylindrical part is subjected to orbital forging.SOLUTION: A mandrel 20 provided on a center axis Cof an upper die 12 to synchronize with the orbital movement of the upper die 12 forms an inner peripheral surface Wb of a cylindrical part Wa of a workpiece W. The mandrel 20 has a separate body from the upper die 12. Moreover, the center axis thereof is supported by the upper die 12 such that a relative angle to the center axis Cof the upper die 12 can change within a predetermined range in a direction to eliminate the bending moment resulted from material flow generated to a workpiece W along with the orbital movement of the upper die 12. Therefore, big bending moment is not generated to the mandrel 20 even if the material flow generated to the workpiece W is received, and thus, the upper die 12 or the mandrel 20 can be prevented from being damaged.
摘要翻译：要解决的问题：当具有圆柱形部件的工件进行轨道锻造时，将工件形成所需形状而不会对模具造成损伤。解决方案：设置在中心轴上的心轴20，与上模12同步，上模12的轨道运动形成工件W的圆筒部Wa的内周面Wb。心轴20具有与上模12分离的主体。此外，其中心轴由上模12支撑使得与上模12的中心轴Cof的相对角度可以在消除由于上模12的轨道运动产生到工件W的材料流所导致的弯矩的方向上在预定范围内改变。因此，即使接收到产生到工件W的材料流，也不会对心轴20产生大的弯曲力矩，因此可以防止上模12或心轴20被损坏。

Thus, the state of pressurized contact of the forming face 50a of the roller part 50 is varied for the component 2 to be formed.

摘要： PROBLEM TO BE SOLVED: To enhance inner diameter accuracy of an inner circumferential surface of a cylindrical part when forming a disk-like component having a cylindrical part on its center by a rocking die forging method.SOLUTION: A stress which causes a material of a workpiece W flow is generated by abutting a workpiece W set in a lower mold 14 on an upper mold 12 and by pressurizing the workpiece W. The stress generated in the workpiece W at this time becomes large for approaching an end part facing the upper mold. A shape within a predetermined range of a center hole Wb in an axial direction of the workpiece W before a rocking die forging process is formed with its diameter gradually larger as it approaches the end part side facing the upper mold 12 in a state that the workpiece W is set in the lower mold 14. The shape of the workpiece W is adjusted in such a manner that as it approaches the end part side facing the upper mold 12, the material amount in the periphery of the center hole Wb is further reduced so that the material flowing to an inner circumferential surface of a cylindrical part does not become excessive. The material amount in the periphery of the center hole Wb is previously reduced so that the flowing amount does not become excessive by previously anticipating the material flowing to the inner circumferential surface of the cylindrical part.

摘要： PROBLEM TO BE SOLVED: To precisely form external tooth profile components, which have a variety of shapes, by upsetting.
SOLUTION: In the early stage of a leading process, the flow of material is promoted by concentrating a load on a contact portion of an annular projection 6a of a punch 601 for the leading process with an annular blank 1 while preventing the increase of working surface pressure applied to a die. Because a forming surface of a punch 602 for the following process has a small annular projection 6a' smaller than the annular projection 6a of the punch 601 for the leading process, the small annular projection 6a' of the punch 602 for the following process is inserted with a clearance S into the annular groove 5c formed in the annular blank 1 by the annular projection 6a of the punch 601 for the leading process. The clearance S functions as a recess for run off. Thus, the charge of material into an external tooth profile forming surface 8a of the die 8 can be promoted while preventing the increase in working surface pressure on a forming die 4.
