Abstract
A tubing cutter configured to cut spine-fin tubing includes a pair of cutting heads pivotally connected and movable between an open position and a closed position. Each cutting head of the tubing cutter includes a blade edge having an arcuate portion with a radius less than an outer radius of a tube of the spine-fin tubing.
Claims18
A tubing cutter configured to cut spine-fin tubing, the tubing cutter comprising:
- a pair of cutting heads pivotally connected and movable between an open position and a closed position;
- wherein each cutting head includes a blade edge having an arcuate portion with a radius less than an outer radius of a tube of the spine-fin tubing;
- wherein the blade edge further comprises:
- a pair of linear portions, the linear portions located on opposing ends of the arcuate portion;
- and
- an angle between the pair of linear portions that is greater than zero degrees.
A tubing cutter configured to cut spine-fin tubing, the tubing cutter comprising:
- a first cutting head pivotally coupled to a second cutting head, each of the first cutting head and the second cutting head having a blade edge with an arcuate portion;
- wherein each of the first and second cutting heads includes a body and a blade that are removably coupled, the blade edge disposed on the blade;
- and
- wherein the blade of each of the cutting heads includes a rounded nose and a bowl region that tapers to the blade edge.
A method of coupling a header tube to spine-fin tubing having a plurality of fins extending radially outward from a tube of the spine-fin tubing, the method comprising:
- positioning a guide of a tubing cutter along an exterior of the plurality of fins to align a pair of opposing blade edges relative to the tube of the spine-fin tubing;
- cutting the tube of the spine-fin tubing with a blade edge of the tubing cutter;
- moving the header tube into contact with a freshly cut edge of the tube of the spine-fin tubing;
- and
- crimping the header tube to the tube of the spine-fin tubing.

- wherein the blade of each of the cutting heads includes a rounded nose and a bowl region that tapers to the blade edge.
A tubing cutter configured to cut spine-fin tubing, the tubing cutter comprising:
- a first cutting head pivotally coupled to a second cutting head, each of the first cutting head and the second cutting head having a blade edge with an arcuate portion;
- a spring operably associated with the first cutting head and the second head to provide a biasing force pushing the blade edges of the first cutting head and the second cutting head into engagement with one another.
