The invention relates to a fine stamping tooling for crankshaft transmission wheels, which comprises a lower hydraulic die set, a lower piston, an upper hydraulic die set, an upper piston, a lower die set, a lower backing plate, a fixed plate, an upper die set, an upper backing plate, a die, a punch, an intermediate plate and an ejector plate, wherein the lower die set, the lower backing plate and the fixed plate are arranged on the upper surface of the lower hydraulic die set sequentially, and the upper die set, the upper backing plate and the die are arranged on the lower surface of the upper hydraulic die set sequentially. On the one hand, the fine stamping tooling is adaptive to fine stamping of various materials by pressure regulation so that defects of parts caused by difference of chemical components of materials and yield strength are avoided; and on the other hand, the blanking precision can be improved and shear surfaces with higher roughness can be obtained. In addition, the fine stamping tooling for the crankshaft transmission wheels overcomes defects of low dimensional accuracy and large burr of workpieces generated in the conventional stamping process, and has the advantages of simple structure, convenience in regulation, high production quality, low manufacturing cost and the like.
