Machine for flaring pipe ends

A machine for flaring a pipe end, comprising a forming die mounted on a support, two jaws forming a clamping tool to hold the pipe end to be flared, first driving means providing orbital motion of the forming die, second driving means providing axial motion of the forming die toward the pipe end and means providing axial motion of the forming die away form the pipe end, said jaws disposed in a stationary jaw holder forming a first block of the machine, a second stationary block facing the first block, a mobile block comprising the forming die, the support for the forming die, and the first driving means, and guiding means interconnecting the two stationary blocks for allowing translational movement of the mobile block, wherein said mobile block is driven in translational motion along the guiding means by a hydraulic cylinder, said hydraulic cylinder comprising a cylinder body, and a cylinder chamber disposed in the second stationary block and a cylinder piston forming an integral part of the mobile block, said hydraulic cylinder supplied by a hydraulic pump mounted on the mobile block.
