ABSTRACT:
The dynamic loading on a double action high speed mechanical cupping press is substantially reduced with multiple stage tooling which forms a batch of cups from a strip of sheet metal with each stroke of the press. Each tooling stage includes a plurality of annular draw pads each opposing a corresponding annular blank and draw die. An annular cut edge surrounds each of the draw pads, and a corresponding die center punch is located within each of the draw pads. The tooling stages are positioned at predetermined stepped elevations so that they sequentially blank the sheet metal to form a series of circular disk-like blanks between the cut edges and the corresponding blank and draw dies, sequentially hold the blanks between the draw pads and corresponding blank and draw dies, and sequentially draw the blanks into cups with the die center punches extending into the corresponding blank and draw dies. The tooling stages are symmetrically positioned with respect to the press center line.
