Paper Title:
Study of Multi-Roll Stretch Forming Process Using Different Clamps
  Abstract

Multi-Roll Stretch Forming process is a new flexible process which is used in forming hyperbolic-degree surface pieces. A series of finite element simulations and experiments have done for the process of forming saddle-shaped parts using two kinds of clamps named Tooth-type clamp and Wave-type clamp. The results show that Wave-type clamp can control the stretching force at an appropriate value. When the stretching force exceeds a critical value, the sheet metal can flow to the opposite direction of Stretch Forming as to maintain that stretching force. The formed part using Wave-type clamp has a better quality than the parts formed using Tooth-type clamp.
