ABSTRACT:
The disclosure relates to a heat resistant die lift system. The system comprises an upwardly opening cavity in a bolster having a vertically movable rail therein. An airbag extends longitudinally of the cavity under the rail. A plurality of rollers are supported by the rail so as to be movable vertically therewith. Inflation of the airbag effects elevation of the rails and rollers into engagement with the bottom of the die and elevation of the die relative to the press bolster. One end of the airbag is telescoped over a complimentary conical nozzle in an air manifold and is retained by a locking block having a conical bore complimentary to the nozzle so as to eliminate the use of adhesives or sealants.
