ABSTRACT:
A double acting press is disclosed having upper and lower vertically reciprocable slides and a bolster assembly therebetween, which bolster and slides support tooling for cutting and drawing a cup-shaped article from a flat blank of sheet metal in response to a cycle of reciprocation of the upper and lower slides. The bolster assembly is releaseably clamped in place with respect to the press frame during press operation and is adapted to be released from the frame and supported for rolling movement laterally outwardly of the frame to facilitate tool inspection, maintenance and replacement operations. Tooling associated with the upper and lower slides is adapted to be supported by the bolster assembly so that the entire tool package is movable into and out of the press confines with the bolster assembly.
