Abstract：

Hydroforming is an effective method to improve material forming limit. Aiming at the large relative drawing height，multi-process and weak forming quality problems for common deep drawing of 2024 aluminum alloy rectangular box, hydroforming with prebulging proposal was designed by analyzing defects during the rectangular boxes forming. Combined with numerical simulation, the sidewall fracture near die entrance and the flange wrinkle were studied and available parameters were obtained. Engineering test was carried out and the influences of cavity pressure, the blank holder gap and the pre-bulging on part formability were analyzed. The high surface quality parts were obtained.
