Metal forming apparatus characterized by rapid cooling and method of use thereof

摘要

A metal forming apparatus characterized by rapid cooling includes a forming tool having a first portion defining a forming surface and a second portion defining a cavity for a working gas. A plurality of fins are in conductive heat transfer relationship with the forming tool. The metal forming apparatus enables a high thermal efficiency mode of operation when the effect of the fins is negated for use during metal forming operation, and a rapid cooling mode for use in preparing for tool maintenance. A corresponding method is also provided.
