ABSTRACT:
A tube cut-off die set includes a compliant cam driver received in a jaw carrying cartridge each adapted to be removably mounted to a die shoe as a separate unit or kit, horizontally and vertically driven tube notching and severing blades which pass through the jaws with the notching blade extending from a cross slide which moves horizontally and has its opposite ends secured during the notching movement, and guide posts having the forward ends of guide bushings rigidified to form a box-like structure to shoulder loads during tube severing. Positioning of a cam drive plate so that a cam slot therein drives the notching blades horizontally when the slot is at its lowest position transfers notching forces to the tube.
