  • Forming tool for forming the undulating heat exchanger surfaces of a heat exchanger via cold bending of a sheet and a method for the realization of the forming profile of such a tool
    Patent number: 7080540
    Abstract: This invention is a device for forming heat exchange elements with corrugated heat exchange surfaces, more particularly inserts, made of a sheet in a formable material, such as metal, between two surfaces, each thus presenting a corrugated profile. This device is of the type comprising at least two plates whose opposing faces present the said corrugated profiles and which are offset from each other so as to define between them a space to take the sheet to be formed (2). The device is distinguished by the fact that the profiles (A and B) are configured in such a way that their displacement in the direction of the thickness of the insert is constant along the corrugations in the space between the profiles. The invention can be used for the production of inserts.

  • Method and manufacturing a hollow turbomachine blade
    Patent number: 5826332
    Abstract: A method of manufacturing a hollow machine blade consisting of two skins ining an internal cavity and interconnected by stiffeners comprises:forging and machining the primary components of the blade, including forming a reserve of material in localized regions of the inner faces of the skins, trunnion forming elements at the ends of the components, and locating holes in the components;deposition of diffusion barriers involving application of a mask, cutting the mask to a predetermined pattern using a special-purpose tool, peeling away portions of the mask, deposition of a coating product, peeling away the remainder of the mask, prefiring treatment, cleaning and checking;assembly of the primary components followed by isostatic-pressure diffusion welding; andsubjecting the assembly to inflation under gas pressure and superplastic forming in a mould in order to shape the skins and form the interconnecting stiffeners, including the steps of cold-debonding the primary components, causing flow of the material reser
