Abstract
A press for forming cans from a metallic sheet includes a first work station having a blanking and drawing punch for cutting a blank from the sheet and drawing a cup from the blank. A second work station includes a redrawing punch for redrawing the cup to a smaller diameter to form a can. The redrawing punch travels through an opening formed in the sheet when the blank is cut from the sheet and acts in concert with the blanking and drawing punch. When the redrawing operation is complete, the redrawing punch reciprocates out of the opening in the sheet, as does the blanking and drawing punch, so that the sheet can advance to the next station. Other subsequent work stations act in concert with the blanking and drawing punch and redrawing punch by passing through openings formed in the sheet when a blank is punched at the first work station.
