Abstract

A knockout punch tool includes a housing, a working head with a cutting die, a hydraulic circuit with an actuator to move the cutting die, a pump providing pressurized fluid, a pressure sensor, a fluid reservoir, and a controller. The controller monitors pressure during knockout operations, determines completion when pressure exceeds a first threshold indicating cutting has started then drops below a second threshold, determines when pressure derivative is at or near zero, verifies the derivative remains near zero for a preset time, and automatically initiates a hydraulic dump sequence to release pressurized fluid back to the reservoir, retracting the cutting die to home position.
