Abstract
Abstract Apparatus equipping a press for a standardized use of die sets and having the following distinctive characteristics. Adapter elements simplify installation and setting up of die sets in a press and include an interchangeable platen replaceable in the press in lieu of replacing bolsters or a variety of rail spacers. Preferred embodiments of the invention feature the use of a single thrust plate which is capable of receiving all standard die sizes for a press. Novel centering structure effects a precision location of the die and precludes relative movement thereof, including rotary or angular turning motion. Preassembled dies are contemplated, substituted as a unit in a press. Handler devices associated with the die set have an alternative use as a means to aid maneuvering of the die set and as a means to lock it against opening and closing movements during storage and handling.
