Patent attributes
A ferrule securing assembly including a die set assembly for reducing a cylindrical ferrule. The die set assembly having a female die and a male die. The female die having a female die opening sequentially defined by a tapered section, a parallel section, and a concave seat. The male die having a concave die face with at least two lateral edges, a medial area, and a radius of curvature. The male die is receivable in the female die opening to move the ferrule through the tapered section so as to forge the ferrule into a substantially oval shape, to move the oval shaped ferrule through the parallel section, and to compress the oval shaped ferrule between the concave die face and the concave seat to forge the oval shaped ferrule into a substantially cylindrical shape. The radius of curvature of the concave die face being greater than the radius of curvature of the concave seat such that contact between the ferrule and the concave die face is shifted from the lateral edges of the concave die face to the medial area of the concave die face as the ferrule is moved through the tapered section.
