    摘要: A tube deforming tool (10) for forming a plurality of dimples (32) in the end of a tube (34) of a predetermined size. The tool has a tapered mandrel (12) extending through a housing (14) containing a plurality of radially movable balls (16). A plurality of longitudinal grooves (20) in the mandrel is the surface that the balls coact with. At the end of each groove is an enlarged recess (40) into which the balls are released at the end of the dimpling or deforming procedure, to permit easy removal of the tool from the deformed tube.
