An Evaluation Of The Fine Blanking Simulation For Seat Recliner Sector Tooth

In this paper, the finite element analysis (FEA) of the fine blanking process was conducted for the seat recliner sector tooth. The sector tooth was a complex part with internal teeth and dimple shapes. It was formed and blanked with a three-station progressive fine blanking tool. The shear surface of the teeth shape, the stress and strain of the part, and the loads of the tool elements were estimated by the results of the simulation. The fine blanking simulation was specifically verified through the comparison analysis of the die roll heights from the simulated results and experiment ones.
