Article Preview

Drawbead is an important factor to automobile sump forming process, proper drawbead setting can improve the forming quality significantly, such as uniforming the sump thickness. Using the drawbead setting theory in dynaform software, the drawbead on the compressive annular part which lie in the shallow part of sump was set, that is, three separate line segment shape equivalent drawbead were arranged alone the shallow part of the die. The influence law of different drawbead parameters to the sump thickness variation has been simulated. Simulating results show that after setting drawbead, reduction of sump thickness is reduced 15% relative to not setting one, and drawbead setting has significant influence to the sump forming quality. It is helpful for forming mold design.
