Stamping dies and guided retainer devices for use in same

A stamping die configured to be used in a press to modify a workpiece, the stamping die comprising:

• a holder that is adapted to be coupled to the press;
• a plate that is spaced apart from the holder and is configured to contact the workpiece;
• and
• a guided retainer that has a pin, the pin defining a first end opposite a second end and that defines a longitudinal axis from the first end to the second end and a radius, the first end having an enlarged portion separated from the second end by an offset, and the pin extending through each of the holder and the plate and the guided retainer includes retainer plate that cooperates with the pin proximate the second end and includes a through-bore located at a distance from the longitudinal axis that is greater than the radius, and is configured to receive a fastener for coupling the retainer plate to the plate,
• wherein the guided retainer movably couples the holder to the plate with the guided retainer being fixedly attached to the plate proximate the first end and movably attached to the holder, and the guided retainer being configured to transfer motion of the holder to the plate during movement of the press to an opened position for insertion of a workpiece into the stamping die.
