Abstract
An apparatus for precisely heating a continuous stream of heading tool dies to a desired temperature for immediate use thereafter in a rivet heading operation comprises a closed-loop transport system having a variable-speed drive and receptacle means for receiving and retaining heading tool dies for transportation therewith, with a first section of the die transport system being exposed to fluid medium having reference temperature below the desired die temperature, and a second fixed-length section of the die transport system being exposed to a constant temperature heat source. The temperature of the dies is thus normalized by exposure to the reference temperature fluid medium, whereafter a metered quantity of heat is transferred to each die by the controlled exposure thereof to the constant temperature heat source as determined by adjustment of die transport speed, whereby the dies are precisely heated to the desired temperature. A preferred embodiment of the instant invention additionally facilitates installation of the thus heated dies on a heading tool which is adapted to receive such dies.
