Abstract:
A method of forming a container component from a strip of metal material fed into a press including the steps of:providing the press with a fixed stock plate defining a first level; feeding the strip material onto the fixed stock plate of the press at the first level; cutting a blank from the strip material at said first level by advancing a draw pad; clamping the blank between the draw pad and a blank and draw die at a second level; forming a shallow cup from the blank by advancing a punch assembly beyond the second level toward a third level and drawing the blank around the blank and draw die while releasing the clamping pressure on said blank exerted by the draw pad; profiling a bottom wall of the cup adjacent the third level to form the container component by continuing to advance the punch assembly through the die to adjacent the third level; and removing the container component from the press at the third level.
