Abstract

A finishing die is used to assemble and finish a shaft sealing. The die performs the multiple functions of staking a metal case to an elastomeric sealing boot, punching a drain hole in the side surface of the boot, and punching a hole locator notch in a flange of the metal case. The finishing die includes a carrier having a cam-type drive connection with a hole punching device so that, during the closing stroke of the forming die, the hole forming device is driven in a transverse direction to form a drain hole in the side of an elastomeric sealing boot which forms part of the shaft seal.
