ABSTRACT:
A marking tool holder (10) for a punch press, in which a plurality of marking tools (46) are mounted in an indexing carrier (38) for selective activation by the press ram (14). A non-positive connection effects driving of the preselected marking tool (46) to eliminate the need for precise adjustment of the marking tool position. In a first embodiment, a pair of very stiff springs (138) are interposed between a ram engaged plunger (124) and a striker (70), while in the second embodiment, a striker mass (158) attached to the striker (70) and carried in a body member (60) which is accelerated by the ram (14) to generate kinetic energy converted into a marking pressure when the marking tool (46) impacts the workpiece (W).
