Tool for cold form flaring tubing ends

摘要

A cold form flaring tool that includes first and second mandrel tips each having the shape of a half conical frustum that includes a base with a base radius and a narrow end with a radius that is less than the base radius. The first and second mandrel tips together form a conical frustum when in a closed position and are insertable in a tubing end when in the closed position. The first and second mandrel tips are expanded outwardly away from each other by pivotally interconnected levers which support the mandrel tips in such a manner that the respective narrow ends of the mandrel tips move outwardly at a greater rate than their respective bases, which retains the mandrel tips in the tubing end while being expanded.
