Investigation of Surface Deflection Controlling in Cylinder Shallow Shell Forming

Abstract:

The surface deflection is an important disadvantage issue in the automobile outer panels forming. It can be controlled effectively through forming process. It is difficult to study the surface deflection because of the complexity of automobile panels. In this paper, a model of cylinder shallow shell is founded, and the measured method and evaluated standard of surface deflection for drawing parts are presented. The influence law of process techniques on surface deflection such as binder force, draw-bead, local force, and shape of blank-hold surface is achieved, which give a basic reference for controlling surface deflection.
