Binding Force Control of Uni-Pressure Cushion in Automobile Panel Stamping 950916

Recently, single action draw with cushion replaces draw with double action presses.
In the single action draw, binding fluctuation problem occurs by its structure.
We applied an NC cushion to prevent the problem. We compared the cushion force wave with and without an NC cushion. The NC cushion showed effective damping.
We studied the binding force control of a side member outer panel. The panel didn't have the formable range of binding. This means the lowest binding force to avoid wrinkling, still had crack problems. We introduce four patterns of binding force control with the NC cushion. As a result, we found the suitable pattern to suppress the surface distortion.
Controlling the binding force shows effectiveness as a means of suppressing surface distortions.
