A hot metal forming apparatus having a pair of dies which are movable between an open and closed position relative to each other. The dies have facing metal forming surfaces corresponding to the shape of the desired stamped part. At least one elongated heat pipe is mounted within at least one die for transferring heat away from the stamped part thus quenching the stamped part.

Hot forming metal die with improved cooling system

A method for hot stamping an iron based component in which the component is heated to a temperature sufficient to transform the component into austenite. The heated component is then positioned in an open stamping die and the stamping die is closed to mechanically change the shape of the heated component to a desired end shape of the component. At least one opening is punched in the heated component and, thereafter, the component is quenched at a rate and to a temperature sufficient to transform the component into martensite.
