<p>An adjustable punch tool assembly (20) has quick release mechanisms which provide for rapid removal and replacement of the stripper plate and punch without the use of tools. The stripper plate quick release mechanism (78) includes slides (80) mounted for axial movement along a front end of the guide by a button assembly (82) and ball bearings (86). The quick release mechanism (30, 36, 38) for the punch includes a retaining knob (30), a generally cylindrical ball bearing holder (36) provided in the punch driver (28), and a ball bearing sleeve (36) wherein the knob is axially shiftable and releasably locked by ball bearings (202) and groove (156) combination therein. The height of the punch is adjusted by rotating the guide (14), punch driver (28), driver sleeve (48) and punch (46) as a unit. An assembly jig (232) which includes a pair of interconnected plates (238, 240) having a punger rod (234) extending therethrough is provided for facilitating adjustment, assembly, and disassembly of the punch unit.</p> |
