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 and rotational movement during the bending operation by tube holding structure arranged to clamp the tube against an extended groove portion of the mandrel. Movement of the forming member about the bending axis is effected by manipulation of a pair of handles. The tube clamping structure includes a hook which is swingably mounted to the mandrel and adjusting structure is provided for adjusting the disposition of the swingable hook to provide a desired clamping force of the hook against the tube. The illustrated adjusting structure includes an eccentric pin and structure for locking the pin in adjusted positions.
