Abstract

A flexible coining die for producing elongated bearing pads of a predetermined radius for use in nuclear reactors. The die is provided with a longitudinal groove having predetermined shape extending across the die. The die is supported by a block which will allow the die to bend at the groove so that the groove effectively "pinches" a bearing pad placed in the groove to be shaped during a coining operation. When the punch is withdrawn, the die returns to its undeflected shape and no longer "pinches" the bearing pad. The pad may be easily removed from the die.
