Abstract
A pair of dies may be coupled to a machine for cutting threaded rods. The machine has a pair of arms each configured to hold one die. At least one arm is moveable relative to the other arm to cause the dies to shear a threaded rod. Each die includes a body having a front face, a rear face, a side face extending between the front face and the rear face, a cutting edge at a junction between the side face and the front face, and a threaded arcuate recess in the side face, configured to receive a threaded rod to be cut. The dies may be substantially identical so the dies can be reversibly attached in either of the arms. The threads of the arcuate recesses may form a continuous helical path about a threaded rod when the dies are closed around the threaded rod.

A pair of dies configured to be coupled to a machine for cutting threaded rods, the machine having a pair of arms each configured to hold one of the dies, at least one of the arms being moveable relative to the other arm to cause the dies to shear a threaded rod, each of the dies comprising:
- a body having a front face, a rear face, a side face extending between the front face and the rear face, a cutting edge at a junction between the side face and the front face, and a threaded arcuate recess defined in the side face and configured to receive a portion of a threaded rod to be cut,
- wherein the dies are substantially identical so the dies can be reversibly attached in either of the arms.
A pair of dies configured to be coupled to a machine for cutting threaded rods, the machine having a pair of arms each configured to hold one of the dies, at least one of the arms being moveable relative to the other arm to cause the dies to shear a threaded rod, each of the dies comprising:
- a body having a front face, a rear face, a side face extending between the front face and the rear face, a cutting edge at a junction between the side face and the front face, and a threaded arcuate recess defined in the side face and configured to receive a portion of a threaded rod to be cut,
- wherein each threaded recess includes a thread having a starting point positioned relative to a circumference of the recess such that the dies are reversibly attached to either of the arms with the threads of the dies forming a continuous helical path about a threaded rod to be cut when the dies are closed around the threaded rod.
A pair of dies configured to be coupled to a machine for cutting threaded rods, the machine having a pair of arms each configured to hold one of the dies, at least one of the arms being moveable relative to the other arm to cause dies held by the arms to shear a threaded rod, each of the dies comprising:
- a body having a front face, a rear face, and a plurality of side faces extending between the front face and the rear face,
- a cutting edge at a junction between each of the side faces and the front face,
- a threaded arcuate recess defined in each of the side faces and configured to receive a portion of a threaded rod to be cut, at least two of the threaded arcuate recesses have different sizes from each other for receiving different sizes of threaded rods,
- wherein the dies are attachable to the arms in different rotational positions so that the at least two different sized threaded arcuate recesses of each die can be positioned to face each other and receive different sizes of threaded rods.
