ABSTRACT:
An accelerator cam set is provided that initiates movement of a binder ring against the force of spring elements, such as nitrogen cylinders. The accelerator cam set is engaged by a ram cam block that engages a transverse cam block that is moved transversely, or horizontally, into engagement with a binder cam block. The accelerator cam set may be used with a stretch draw die, double pad stretch draw die, or inverted toggle die.
