Abstract:
A die is configured for use with a punch capable of piercing and cutting a workpiece. The die includes a base wall having a perimeter, an outer surface and an inner surface, a depending wall extending from the perimeter, a passageway extending through the base wall, and a central axis extending through the passageway. The outer surface of the base wall is perpendicular to the central axis. The inner surface of the base wall has a first portion which is angled relative to the central axis at a first angle which is greater than 90 degrees, and a second portion which is angled relative to the central axis at a second angle which is greater than 90 degrees. The first and second angles are different. The first portion extends from the depending wall to the second portion. The second portion extends from the first portion to the passageway. The second portion engages the punch when the punch is fully inserted into the die.
