Definitions

  • constriction means comprise a mould with at least one inwardly movable region
  • the relative movement is effected by forcing the movable region from a position in which the tubular stock can be introduced into the mould to a final position in which the tubular stock is actively forced to adopt a final configuration
  • constriction means comprise a die having an aperture therethrough of cross-sectional shape changing from a shape into which the stock can be introduced to a final desired shape
  • the relative movement is effected by forcing the stock through the die whereby the stock is actively forced to adopt the final desired shape
  • a moulding tool comprises spaced upper and lower members 10, 11 having facing surfaces 12, 13 respectively. In between these surfaces are provided side members 14, 15 each having facing surfaces 16, 17 respectively. Urging means, not shown, are provided to urge the side members 14, 15 inwards towards each other in a controlled manner.
  • the surfaces 12, 13 and 16, 17 form the interior of the mould and are thus shaped to form the final configuration of an article to be moulded when the side members are in the fully inward position.
  • a section 20 of tubular stock of superplastically deformable material is sealed at both ends and filled with an inert gas. It is placed in the mould when the side menbers 14, 15 are in the outward position.
  • the section is conveniently of circular form, but other shapes can be utilised with effect.
  • the side members 14, 15 When heated to within the temperature range at which superplastic deformation can take place, the side members 14, 15 are urged inwards to contact and gradually deform the tubular stock.
  • the gaseous pressure within the section of tubular stock causes the material thereof to be urged against the interior of the mould as illustrated in Figure 2.
  • the gaseous pressure is either the result of charging the section with a pressurised gas initally, or the residual pressure generated by the constriction effect of the mould side portions. Naturally it can also be a combination of both.
  • Figure 3 shows a final configuration where the side members 14, 15 are moved to their most inward position.
  • two opposed surfaces 16 -, 17- urge two regions of the circular sectioned stock (which regions were originally diametrically opposite of one another) together to form a double layered web of a generally I-sectioned beam.
  • diffusion bonding can be effected at this region by causing the side members 14, 15 to be sufficiently strongly urged to produce the necessary bonding pressure.
  • the final article is an I-sectioned beam with hollow flanges at the top and bottom joined by a double layered diffusion banded web.
  • a similar mould tool to that of the previous figures is provided, but is modified to have regions formed in the surfaces 12, 13 of the upper and lower members to accommodate capping members, 21, 22.
  • These capping members are of diffusion bondable material so that when the material of the cylindrical stock 20 is urged against them under a suitable pressure exerted by the pressure within the stock section under the action of the urgeable side memembers 14, 15 diffusion bonding at regions 23, 24 takes place.
  • a reinforced I-section article can be formed.
  • the above methods and apparatus can be used to form constant or varying sectioned articles.
