The present invention concerns an apparatus for forming into shape one end portion of a rod-like metallic work such as a pipe. The apparatus comprising a holding member to hold the work, a split die composed of at least two movable die members, and a pressure die. Both the split die and the pressure die have engaging portions which move the split die in directions perpendicular to the axial direction with movement of the pressure die in the axial direction. The split die clamps the outer surface of the end portion of the work. Further the pressure die moves toward the holding member and forms the end portion of the work into shape between the split die and the pressure die. So, as set forth hereinabove, both clamping for the split die and forming for the work can be done by the one stroke of the pressure die. Thus, it is not necessary to provide two drive sources for moving the split die and for moving the pressure die, and therefore it is possible to attain simplification of equipment.
