Abstract
A crimping die assembly comprising a plurality of die fingers, a holding unit for holding the die fingers in a working relationship, the holding unit comprising a retaining ring having a plurality of substantially evenly spaced openings for receiving the die fingers therein for holding the die fingers at one end of the die assembly, each die finger having a connecting part connecting the die finger to the retaining ring, each connecting part permitting radial movement of its respective die finger with respect to the central axis of the retaining ring, and a springing arrangement integrally associated with the connecting parts tending to force the die fingers radially outwardly with respect to the retaining ring, the top surfaces of the die fingers extending beyond the top surface of the retaining ring so as to receive pressing forces directly from a ram through a pusher ring that engages the top surfaces of the die fingers when the crimping die is used to crimp a workpiece.
