ABSTRACT:
An overload assembly is disclosed for use with a tube cutting apparatus of the type having a die set for holding a tube while a blade cuts the tube. The die set comprises two die jaws having cam followers which contact a die jaw cam to move the die jaws to clamp the tube. The overload assembly allows one of the die jaws of the die set to stop moving when an obstruction is encountered. The overload assembly includes a spring mounted through a lever arm to the cam follower. An overload biasing force is applied to the cam follower through the lever arm. If an obstruction force exceeds the overload biasing force, the lever arm is rotated and the effective length of the lever arm is reduced, causing the overload biasing force to decay to a lesser value. A scarfing blade may initially score the tube prior to cutting. In one embodiment, the overload biasing force is applied to the die jaw which does not encounter a binding force between the scarfing blade and the tube.
