ABSTRACT:
The invention relates to a press driven work tool module comprising a power unit and a work unit. Each unit comprises a fluid filled cylinder, a piston for reciprocation therein, and a piston rod. Hydraulic fluid within the power stroke displacement space of the power cylinder is in communication with hydraulic fluid in the work displacement space of the work cylinder, and hydraulic fluid within the return displacement space of the power cylinder is in communication with hydraulic fluid within the return stroke displacement space of the work cylinder. The power cylinder is provided with a moving top plate connected to the power piston rod and a spring arrangement for urging the top plate and power piston rod to the return position, such that a drive force acting on the power piston rod moves the power piston and work piston to the power and work ends of the respective cylinders against the spring bias. The system is hydraulic and eliminates the need for pressurized gas, avoiding problems such as contamination, worn seals, loss of pressure over time, and need for recharging.
