Abstract
A tube bender construction for manual operation in bending a tube. The tube bender includes a mandrel defining a bending groove into which the tube is urged by a forming member mounted to the mandrel to swing about a bending axis of the bending groove. The tube to be bent is held against longitudinal movement during the bending operation by tube holding structure arranged to retain the tube against such movement. Movement of the forming member about the bending axis is effected by manipulation of a pair of handles. The mandrel defines an extension adapted for adjustably mounting the tube holding hook to further define structure for adjusting the disposition of the tube to be bent to be accurately tangential to the bending groove at a bend start position thereof.
