摘要： PROBLEM TO BE SOLVED: To minimize machining allowance of shaft parts in the forming method of a crankshaft shape material for which turning of the shaft part is eliminated with only grinding left workable.
SOLUTION: The impression profile 2b of the parts 1e, 1f other than the shaft parts 1a-1d is ground more than 2.0% of the shaft diameter each vertically from the center CL of the journal shaft part 2ba having complete roundness. Also, using a sizing mold 2 with an area reduction rate of the shaft part 3.0% or higher, the crankshaft shape material 1 is partially formed for sizing. After that, the accuracy-required shaft parts 1a-1d of this crankshaft shape material 1 is finished, with at least rough turning eliminated, to manufacture the crankshaft. In the sizing process, while both side faces of the shaft width are positively restrained, only the shaft parts are reduced to reinforce metal flow in the axial direction; therefore, uneven deformation of the shaft width left and right is suppressed, greatly decreasing the bend in the shaft width direction, and enabling the machining allowance of the shaft parts to be reduced by half in the subsequent machining process. Moreover, the service life of the tools to be used for trimming is prolonged.

摘要翻译：要解决的问题：为了最小化轴部件的成形方法中的轴部件的加工余量，其中仅通过研磨即可消除轴部件的转动。解决方案：除了轴部1a-1d以外的部分1e，1f的压痕轮廓2b，与具有完整圆度的轴颈轴部2ba的中心CL垂直地分别大于轴直径的2.0％。此外，使用轴部的面积减少率为3.0％以上的定径模具2，部分地形成曲轴形状材料1以进行上胶。此后，对该曲轴形状材料1的精度要求的轴部1a-1d进行精加工，至少粗略的倒车消除，制造曲轴。在上浆过程中，当轴宽度的两个侧面被积极地限制时，只有轴部分被减小以加强沿轴向的金属流动; 因此，左右的轴宽度的不均匀变形受到抑制，大大降低了轴宽度方向的弯曲，能够在后续的加工过程中使轴部的加工余量减少一半。此外，用于修整的工具的使用寿命延长。版权所有（C）2004，JPO＆NCIPI

CONSTITUTION:A binder is mixed with inexpensive powder of Fe-C systems and is packed in preheated sectional dies 11, whereby it is lightly compressed and a premolding 13 provided with four recesses, etc., is obtained. This premolding 13 is inserted into a die 15 in such a way as to be fitted to a core 14, and high- grade powder 18 of Fe-C-Ni-Cu type or the like is supplied into the space enclosed by the inside circumferential surface of the die 15, the outside circumferential surface of the premolding 13 and the inside surface of a lower punch 16. Thence, an upper punch 19 is lowered to compress the premolding 13 and the supplied powder 18 simultaneously. According to this method, the need for partition cylinders is eliminated, set-up of tooling is simplified, and the joint strength between dissimilar metallic materials is improved. This molding method is adapted to production of gears, etc., of plural-layered structure.
