A metal-forming die according to the present invention includes die blades with convoluted opposed side surfaces that correspond to variable-width features on the working surface of the die. The convoluted side surfaces and variable-width working surface features permit the impression left by one die blade to fill space taken from an impression made by a laterally adjacent die blade. Such a die permits formation of working surface shapes not possible with flat-sided die components. The die is manufactured in discrete longitudinally extending components, or blades. Dividing the working surface of the die into longitudinally extending portions, each carried by a die blade allows conventional machining processes to be employed in forming the working surface on each die blade. An additional machining process cuts complementary shapes on the sides of the die blades. The die blades and their corresponding working surfaces interfit, or nest together.
A metal-forming die comprising:
A method of manufacturing a metal-forming die adapted for use in a press, said die comprising a plurality of adjacent die bodies having longitudinally extending working surfaces, opposed side surfaces extending from said working surface and a width between said opposed side surfaces, said die bodies clamped together with said side surfaces against one another and adjacent working surfaces defining a forming surface of the die, said method comprising:
