Abstract
A cooling gas system for a can bodymaker tool pack is provided. The cooling gas system uses a compressed gas to cool a punch and/or a die pack. That is, a compressed gas is delivered to at least one location adjacent the punch and die pack. A nozzle assembly directs the compressed gas toward a selected location. As the compressed gas passes through the nozzle assembly, or immediately after passing through the nozzle assembly, the compressed gas expands. As is known, an expanding gas cools as it expands. Thus, a cool gas is directed to the surface of the punch and the die pack. The cool gas absorbs heat from the punch and die pack thereby cooling the heated components.
