Definitions

  • the present invention relates to holding tools used to hold metal parts during heat treatments of such parts such as annealing, brazing, conformations, etc.
  • these supports are usually very bulky and heavy. They reduce, therefore, the loading capacity of the oven used for heat treatments while being difficult to handle. They also have a significant thermal inertia, which results in significant energy consumption for the temperature setting of the tool and requires a long cooling time reducing the productivity of the installation. In addition, this significant thermal inertia limits the thermal gradients needed to obtain the desired microstructure.
  • This type of support also has a high coefficient of thermal expansion, most of the time different from that of the material of the part to be treated, which limits its use to parts having simple geometric shapes and requires the provision of rework. machining on the parts to conform to their final geometry.
  • the invention proposes a holding tool comprising:
  • the tooling comprises a plurality of pairs of jaws placed on each side of the metal part, each pair of jaws being slidably mounted on the support structure.
  • the movements of the room during mounted or lowered in temperature, can be accompanied by the jaws without exerting stress on the workpiece and while following the precise geometry of the latter defined by the support structure of the tooling.
  • the invention also relates to a heat treatment installation comprising an oven and one or more holding tools according to the invention placed inside the oven.
  • FIG. 5 is a side view of part of the holding tool of FIG. 3;
  • the invention applies generally to tools for maintaining metal parts in precise geometry during processing involving temperature rises, such as annealing, quenching, tempering, maturing, conformations or hot brazing. or any other treatment involving temperature variations.
  • a particular, but not exclusive, field of application of the invention is that of the hot conformation of titanium or similar parts of large size and whose geometry must be very precisely respected or heat recovery (conforming parts out of tolerance Cold).
  • SiC / SiC silicon carbide-silicon carbide
  • the holding elements of the metal part are slidably mounted on the support structure, they adapt to the expansions and shrinkages of the part during climbs and descents in temperature during the heat treatments by following the displacements of the latter while respecting its geometry because the displacements are made according to the housing geometry of the support structure.
  • the angular wedge 543 is attached to a side wall 5144 of the support structure while the wedge 542 is attached to the opposing side wall 5124.
  • support plate 5134 provided with slides 5134a and 5134b to allow movement of the jaws is fixed on the angular wedge 543 with interposition of a spring element 534 ensuring the elastic holding of the workpiece.
  • the part 680 is also maintained on its opposite side to the spacer elements 620 to 625 by support plates 640 to 645 each respectively resting on one of the rollers 6111 to 6116 of the side wall 6110.
