Abstract
A single action draw press and a draw die set for the single action draw are disclosed. The single action draw press and die include a bolster and a stationary punch. A cushion is assembled to the bolster to support a binder ring that is adapted to be engaged by a die attached to a press ram. The die is reciprocated by the press ram relative to the bolster while a mechanical lock engages the die and the binder ring. The die contacts the binder ring and a mechanical lock secures the die and binder ring together while the die draws a panel over the stationary punch.
