Abstract

For the manufacture of hollow and profiled bodies a mould (1) equipped with a vibration system (2) is provided and is mounted on a guiding and driving system ( 3 ) capable of rotation and translation. A heated billet ( 5 ) placed in the mould (1) is pushed by a pressing device (4) towards a deformation mandrel (6) lubricated by a lubrication system (8), and connected to a mandrel driving and positioning system (7) which on its turn may have a relative rotation and translation motion compared to the machine's body, which ultimately gives a combined movement when deforming the billet. Following metal working, a hollow or profiled body (10) will result with an outer profile according to the profile given by the inner profile and motion of the mould and an interior profile corresponding to the profile generated by the outer profile and motion of the mandrel.
