Abstract: The present invention is a pair of split dies comprises of a pair of fixed die halves, with each fixed die half having an associating movable die insert. The pair of split dies are separated from each other in order to admit a cutting blade therebetween and a variable width opening is formed between each of the fixed die halves and their associating movable die inserts. The movable die inserts move toward the fixed die halves and thereby decrease the width of the openings in response to cam means attaching to the blade which engage movable cam tracks located on the movable die inserts opposite the openings. The openings close on tubing located within the openings so that the tubing is held stationary on either side of where the blade cuts the tubing. The movable die inserts move away from the fixed die halves and thereby increase the width of the openings in response to disengagement with the cam means.

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.
