(57) The task of securing dies (26, 36) of a die set (24) to appropriate supports (15,
16) such as for example, the die shoes of a set of die shoes or to upper and lower
platens (12) of a punch press so that the dies are in precise alignment can be simplified
by utilising expandable diameter fasteners (48, 50) to secure the dies to the supports.
Each fastener used is located within a hole (44) extending through one of the dies
and within an aligned hole (46) in the adjacent support. The fasteners used are of
such a character as to be capable of firmly securing the dies and the supports even
if such holes of a set of such holes are of not precisely the same diameter. Preferably
each die is secured in place utilising at least two of such fasteners.
