Paper Title:
The Effect of Discrete Grippers on Sheet Metal Flexible-Gripper Stretch Forming
  Abstract

Flexible-gripper stretch forming is a new flexible manufacturing process of sheet metal. Four numerical simulation models of discrete grippers were established using finite element method, the effect of the numbers of grippers on stress distribution, thickness distribution and gripping surface shape of the spherical parts were studied. The results show that the clamped edge of the spherical parts formed by using integral grippers is straight,the tensile stress distribution is uneven and the thickness is obviously reduced. However, the stress distribution on the parts formed by using discrete grippers stretch forming is relatively uniform, with the increase in the numbers of grippers, the thickness increases, and the more gripping surface curvature of the parts is close to the curvature of die, the better forming quality of the parts is.
