METHOD AND SYSTEM PROPOSED FOR THE MANUFACTURING OF HOLLOW PROFILE OBJECTS

摘要

This invention proposes a method and system addressing the manufacturing of hollow or profiled bodies from billets having the proper temperature for plastic deformation. The method for the manufacturing of hollow and profiled bodies, according to the invention, eliminates the disadvantages mentioned above by requiring the use of a single machine to produce the hollow or profiled body in a mould equipped with a vibration system, mould mounted on a guiding and driving system capable of rotation and translation motion following the deformation direction, using a billet heated to the temperature required for deformation which is pushed by a pressing device towards a deformation mandrel lubricated by a lubrication system, mandrel which can have many shapes and is connected to the mandrel driving and positioning system 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 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. The system for the manufacturing of hollow and profiled bodies, according to the invention, consists in a mould 1 equipped with its own vibration system 2 and connected to a motion and guiding system 3, a pressing system 4 pressing on the billet 5 towards the deformation mandrel 6 mounted on the driving system 7, a lubrication system 8 and a central command and control unit 9, to obtain the hollow or profiled bodies 10 after processing.
