Module cam and method for aligning and fastening a tool

摘要

To facilitate aligning and setting of a punch (26) in a die (27) of a press machine, a module cam assembly (1) comprises a cam unit and a fallen L-shaped module base (5). The cam unit comprises a cam driver (2), a cam slider (3) equipped with a positive return (6) to be driven by the cam driver, and a cam base (4) holding the cam slider. The cam slider (3) has a punch retainer (26a) on its vertical side. The fallen L-shaped module base (5) bears the cam unit, and is adapted to be laid and fastened to the lower die holder. The fallen L-shaped module base (5) has a button die (27) on its upright leg (5b) in confronting relation with the punch retainer (26a) of the cam slider. This arrangement facilitates the centering and fastening of any tool to the press machine.
