Abstract：

As the foundation of fine blanking technology, the anti-eccentric load performance of fine blanking press is a key factor affecting its eccentric stamping capacity. Based on the triple-level accuracy requirement of hydraulic fine blanking press, the model of hydraulic fine blanking press was firstly established by the finite element topology decomposition approach. By applying eccentric loads at different distances from the center line of slider, the maximum eccentric load at different positions of slider were calculated by the 3D thermo-mechanical coupled numerical simulation technology, and the relationship between deflection displacement of slider and eccentric load was achieved. Furthermore, the relation of point displacement and eccentric load was fitted by curve fitting method, and the anti-eccentric load curve was drawn along the length and width directions of slider respectively. Finally, the anti-eccentric load curve was verified by experiment. The results show that the experiment data are consistent with the standard theoretical values, the anti-eccentric load curve is exponentially distributed, and the anti-eccentric load capacity in the width direction of slider is greater than that in the length direction.
