Definitions

  • the present invention relates to a thermal treatment installation comprising an oven, at least one treatment tank and means for transferring loads between said oven and said tank.
  • Patent EP 0533615 describes an installation of this type, which includes a furnace with vertical arrangement open downwards and located in one position upper, a bin fitted with an elevator and placed in a lower position, and a horizontal access route, installed at the height of the base of the tank, equipped with loading means and a charging lift placed at side of the tank so as to raise a load placed by the means of loading on the elevator to introduce it into the oven.
  • This is mobile horizontally between a position above the elevator and a position located above the tray.
  • a plan of sliding is arranged so that the horizontal displacement of the oven drives the load supported by the elevator on the sliding plane.
  • the above installation uses known solutions to place the load on an elevator before introducing it into a heating enclosure including a gas-tight bell which protects the components of the charge against oxidation, the elevator then bringing the load in a starting position after heat treatment.
  • the transfer of the load is made by shifting on a sliding plane.
  • Shifting is, in fact, carried out by the oven itself which pushes the load from one position to another, this displacement requiring a refocusing by report to the coordinates of the new enclosure in which the load must be introduced.
  • the dimensions of the load support must therefore allow sufficient positioning clearance inside the heating bell of the oven. After the sliding thrust on the sliding plane, this game is caught up initially and requires the oven to go back to refocus the load on the new enclosure.
  • the sliding plane is a cold zone over which the charge.
  • any temperature variation is detrimental to good quality of the treatment which follows the rise in temperature to a determined degree.
  • Variable load temperature modification in terms of sliding itself of variable temperature is therefore detrimental to the quality of the desired treatment.
  • the components to be heat treated must be arranged on the load carrier without their respective position being changed during the transfer after the desired heating.
  • Using a solution of shifting on a sliding plane through the oven itself causes vibrations which adversely affect the position of components on the load support.
  • the displacement by shifting of the load is planned to convey it opposite several tanks arranged linearly or rotatably.
  • Load must be able to be inserted in any bin according to a program established, the passage by shifting of the load over the tanks not provided according to the program requires each time that the opening of the tank not planned is obstructed by the introduction of a "plug", this both on the way to and from back, so that your load does not fall into the first bin open but well in the programmed one.
  • the present invention aims to provide an improved version of the heat treatment installation described in the document above.
  • the installation according to the invention is characterized in that its variable-shaped frame consists of four identical arms, articulated to each other, which form a square in the open configuration and a diamond in the closed configuration.
  • the support plate is circular and extends, towards the bottom, by a tubular sleeve whose height is chosen according to the level that the support tray must occupy inside the oven.
  • each arm is pivotally mounted in their center on studs secured to the bottom of the oven.
  • each arm is provided a circular central cut open towards the inside of the frame, the four cutouts delimiting a circle whose diameter is slightly greater than outside diameter of the support plate.
  • the frame is advantageously associated with a control lever secured to one of his arms.
  • the installation comprises at least one treatment tank for inside of which are loaded / unloading means and on which the oven rests.
  • the installation includes several treatment tanks juxtaposed inside each of which are mounted loading / unloading means and above which the oven can be moved.
  • FIG. 1 shows a mobile oven 1, the bottom of which has an opening circular 3 and which can be moved, by means known to those skilled in the art loom, above a series of juxtaposed bins 4a-b-c-d-e-f (fig. 9) with each of a loading / unloading or lifting system 5 allowing to introduce into the oven - or to extract from it -, through the opening 3, a support plate 6 on which are deposited components to be treated 7.
  • the opening 3 has a diameter slightly greater than that of the support plate 6 to allow its free passage.
  • the furnace 1 is of the type known under the name of bell furnace. he has four side walls 8. Heating bodies 9 are arranged on its walls and are covered with a jacket 10. A turbine, not shown, ensures the homogeneity of the speeds of the treatment gases in the enclosure.
  • the support plate 6 is circular and extends downwards by a tubular sleeve 11.
  • the tank 4a can be used to place the components 7 on the support plate, the bins 4b-c-d are heat treatment tanks themselves and the 4th tank is used for unloading of components.
  • the oven 1 has, under its bottom 2, a frame with variable geometry 12 capable of taking a first configuration, known as open configuration (FIG. 1), in which it defines, opposite opening 3, a window in the shape of a square authorizing the free passage of the circular support plate 6 and a second configuration, called closed (fig. 2), for which the window is partially closed in the shape of a diamond so as to allow only the passage of the elevator 5, the frame 12 then serving as a base for the sleeve 11 when said elevator is removed from the oven.
  • open configuration FIG. 1
  • fig. 2 closed
  • the frame 12 is formed by four arms identical 13 a-b-c-d connected to each other by four joints 14.
  • the arms 13a and 13 c which face each other, pivot in their center on tenons 15 secured to the bottom 2 of the oven.
  • Each of the arms 13 is provided with an open circular central cutout 16 towards the inside of the frame, these four cutouts delimiting a circle whose diameter is very slightly greater than the outside diameter of the support plate 6 which can thus pass freely through the frame 12 when the latter is in open configuration.
  • a control lever 17 is hingedly mounted on the arm 13c thanks to a tenon 18.
  • the frame When it occupies position O, the frame is in open configuration (fig. 1) and delimits a square window.
  • the installation according to the invention operates in the following manner.
  • the oven is, for example, positioned above the first tank 4a.
  • the lower end of the sleeve 11 is then above the level of frame 12.
  • the control lever 17 is then moved manually to its position F, which causes the frame 12 to pivot on the two studs 15 and, in at the same time, its deformation, thanks to the joints 14, until it takes its diamond configuration (fig. 2), as shown in figure 4. then observe that the arms 13 offer four support zones 20, set evident in Figure 2, which are located exactly under the sleeve 11 of the support plate.
  • the components to be treated 7 arranged on the support plate 6 can then be heated by oven 1 to the desired temperature, after which the assembly is transferred horizontally, as is, over one of the other bins 4.
  • oven 1 By a reverse process to that just described, the lever 17 still being in position F and the frame 12 in its diamond configuration, the elevator 5 of the affected bin raises the support plate 6 so as to bring it above of the level of the frame 12.
  • the lever 17 is then put in position O to open the frame in its square position, which allows to lower the elevator 5 and the support plate 6 in the tank for new operations treatment.
  • the installation according to the invention can have several ovens 1 allowing several to be heated at the same time loads of components to be treated 7.
  • Figures 6, 7 and 8 correspond respectively to Figures 3, 4 and 5. Their sole purpose is to show that the sleeve 11 of the support plate 6 can be of variable height, thus allowing, with the same installation, place the load of components to be treated 7 at any desired height at inside the oven 1.
