ABSTRACT:
Die alignment apparatus for aligning redraw and ironing dies in die slots of a tool pack of a crank and slide press includes an alignment die and a calibration fixture. The alignment die includes a die body and a pair of position transducers disposed in the die body along separate ones of transducer axes. The calibration fixture locates the alignment die by a pair of locator pins that engage an outer cylindrical surface of the alignment die; and the transducers are calibrated by contact with a calibration punch that is a part of the calibration fixture. In use, the alignment die and an alignment punch replace the production punch and the redraw and ironing dies. The alignment die is placed in one die slot of the tool pack, and the alignment die is positioned along X and Y axes by adjusting wedges that are moved by rotationally positioning adjusting sleeves until the readout device indicates accurate alignment of the alignment die with the alignment punch, and the alignment die and the alignment punch are replaced by a production die and a production punch.
