Abstract：

Hydraulic deep drawing technology was introduced into the forming of tailor rolled blank (TRB) in order to further improve the formability of TRB, and the main focus was placed on the effect of pre-bulging process. Then, the hydraulic deep drawing process for cylindrical part of TRB was studied by the numerical simulation technology, and the reasonable loading path of liquid pressure was determined. Furthermore, the thickness transition zone movement and the thickness thinning of TRB under different pre-bulging pressures were discussed, and the proper pre-bulging pressure values were obtained. The results indicate that as the pre-bulging pressure increases, the maximum thickness thinning rate of TRB shows the trend of decreasing first and then increasing, and the movement amount of thickness transition zone presents the trend of gradually decreasing. When the pre-bulging pressure is 1.00 MPa, the smaller maximum thickness thinning rate is achieved, and the movement amount of thickness transition zone is restricted to a lower level to improve the formability of TRB.
