Abstract：

For the problems such as thinning and thickening of the local thickness for oval head in the hot stamping process, the three-dimensional finite element analysis on the hot stamping process of oval head was conducted by software Deform, and the distributions of equivalent stress, equivalent strain and thickness of head along the radius of blank at different temperatures were obtained respectively. Then, the thickness of head was calculated according to GB/T 1503—2011, and the optimal load force and working environment temperature parameters of manufacturing head were obtained. Finally, the head was formed by a 4500 t head hydraulic press, and the thickness distribution of head was basically consistent with the simulation result. The results show that during the hot stamping process, the equivalent stress and equivalent strain of head at 150-300 mm of blank radius change sharply, and the maximum change value after forming is located at the straight edge section, where the force is the weakest. For S30403 stainless steel sheet, when the blank temperature is 1000 ℃, the thickness change of oval head after forming is the most ideal, and the head quality is better.
