Abstract
A press machine includes at least one mobile bolster movable with respect to the press machine, a plurality of die assemblies mounted on the mobile bolster and arranged in a row, a plurality of handling bars disposed in retracted positions between the die assemblies and movable, when one pressing cycle is completed, for gripping and transferring a plurality of workpieces successively through the die assemblies, and a plurality of handling bar gripping devices disposed in the retracted positions closely to the opposite sides of the side assemblies. A method of changing die assemblies comprises the steps of moving the mobile bolster out of the pressing machine, tilting the handling bar gripping devices away from the die assemblies, carrying the die assemblies away from the mobile bolster, carrying new die assemblies onto the mobile bolster in an order opposite to that in which the die assemblies were carried away from the mobile bolster, and returning the tilted handling bar gripping devices to upstanding positions after the new die assemblies are carried onto the mobile bolster.
