Abstract

An I/O endforming tool for forming an end of a tube, the tool having a cone ring expandable and contractable conical I/O jaw assembly, a barrel assembly, a plurality of I/O
fingers and mandrel assembly, wherein the I/O jaw assembly has a plurality of conical jaw segments, one segment adjacent two neighbouring segments, each segment having a recess within each of its sides adjacent each neighbouring segment and biasing member retained within each recess to effect a biasing effect between adjacent jaw segments the improvement wherein each recess formed at a portion of the outer circumference of each segment as to define a radial trough when the jaw assembly is in its expanded position; and the biasing member is a solid, non-metallic deformable member retained within a circumferential recess defined by a pair of adjacent the troughs when the jaw assembly is in its contracted position.
The process of manufacture provides improved saving in time, handling, efficiency, consistency and quality. The deformable member is preferably formed of and provides for greater force, higher grease and fluid resistance and tolerance and rust resistance over metal coil springs presently in commercial use.
