ABSTRACT:
A module for selectively deploying a reciprocable tool, such as a hole punch, which is reciprocated by a press. The module includes a housing which is attached to the ram of the press. The housing retains a reciprocable tool within a bore for movement between an extended position and a retracted position. The reciprocable tool is connected to the housing by means of a telescopic linkage comprising a cone clutch having resilient fingers that selectively grip a pin. The housing includes a conical surface which engages beveled portions of the resilient fingers holding them in a closed position. A spring biases the cone clutch to its closed or gripping position unless air pressure is supplied to an air chamber which counteracts the biasing force of the spring to open the resilient fingers. When the resilient fingers are open, a shifting means comprising a spring, or alternatively a solenoid, is effective to shift the pin between an extended position and a retracted position within the cone clutch. A controller is disclosed for selectively shifting the reciprocable tool between its extended position and its retracted position within the module wherein a card having air flow control holes corresponding to modules selected for changeover is inserted in the controller.
