Drawing process of hydroforming deep rectangular box

YU Nian-sheng(Guangdong Vocational College of Mechanical & Electrical Technology,Guangzhou,Guangdong 510515,China)  
The drawing process for hydroforming a deep rectangular box was analyzed by using finite element simulation software DYNAFORM,and the effect of blank holder force and liquid pressure on the forming quality was researched.The result indicates that proper blank holder force and liquid pressure will help to reduce the occurrence of drawing defects and the application of hydroforming can get more uniform wall thickness.
