Abstract
Metal forming apparatuses provide enhanced thermal efficiency by reducing thermal conduction from a forming tool to a shield. In one embodiment, a shield extends between a tool and a mounting plate, and is in conductive heat transfer relationship with the tool via a plurality of protuberances. In another embodiment, a shield extends between a tool and a mounting plate, and thermally insulating material separates the tool and the shield.
Claims18
A metal forming apparatus comprising:
- a metal forming tool;
- a mounting plate to which the metal forming tool is operatively connected;
- a plurality of protuberances that are spaced apart from one another such that open spaces are defined between the protuberances;
- and
- a shield extending between the mounting plate and the forming tool and being in conductive heat transfer relationship with the tool via said protuberances.

A metal forming apparatus comprising:
- a metal forming tool;
- a plate to which said metal forming tool is operatively connected;
- a shield extending between the forming tool and the plate;
- and
- thermally insulating material separating the shield and the forming tool;
- wherein the shield is in conductive heat transfer relationship with the metal forming tool only through the thermally insulating material.
