Abstract
A die liner for use in a die having a die body wherein the die body is configured to form a workpiece. The die liner is a discrete structure that is configured to be used in conjunction with the die body. The die liner defines a forming surface for forming the workpiece and is configured to have at least one characteristic that is different than a corresponding characteristic of the die body such that the die liner increases the durability of the die.
Claims29
A die for use in a forming apparatus that uses inductive heating, the die comprising:
- a die body having a cast portion that is formed from a first material;
- a discrete liner coupled to the die body, the liner defining a die cavity and a forming surface, the liner being formed from a second material that is different from the first material, the second material also being a fiber-reinforced, sintered ceramic composite that is relatively more durable than the cast portion of the die body;
- and
- wherein the fiber-reinforced, sintered ceramic composite comprises a plurality of continuous composite fibers.
A die liner for use in a die having a die body, the die liner being a discrete structure that is configured to be used in conjunction with the die body, the die liner defining a forming surface for forming the workpiece, the surface for forming the workpiece being made of a fiber-reinforced, sintered ceramic composite;
- and
- wherein the fiber-reinforced, sintered ceramic composite comprises a plurality of continuous composite fibers.
A method for forming a part at elevated temperature comprising the step of:
- expanding a heated blank into contact with a forming surface in a die, the forming surface being made from a durable, inert, fiber-reinforced, sintered ceramic composite;
- and
- wherein the durable, inert, fiber-reinforced, sintered ceramic composite comprises a plurality of continuous composite fibers.
