Definitions

  • the present invention relates to a method hooking and unhooking of a load in a heat treatment facility, and more particularly in such an installation comprising a oven having an opening facing downwards.
  • the present invention also relates to a thermal treatment installation allowing the setting in work of this process.
  • Conventional heat treatment systems have one or more ovens with an opening facing downwards, generally referred to as bell ovens and means for loading and unloading the parts or loads to be treated in and from the oven (s).
  • Charges are loaded into the ovens generally as follows: the load is placed on a support plate in the form of a rigid grid honeycomb plane placed on an elevator which is movable between two positions respectively low and high.
  • the oven has studs or brackets in its lower part retainers that protrude radially from the inner wall of the oven. These studs give opening the oven an indented outline.
  • Grid has a complementary outline and dimensions slightly smaller than those of the opening from the oven, so that the grid can pass smoothly with the load through the opening. So the grid with the load can be inserted from the bottom, in the oven opening by the elevator while the grid is oriented parallel to this opening.
  • the load release operation is carried out simply by repeating the above process so reverse.
  • the main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a process and an installation which allow to carry out in a simple and economical way the hanging and unhooking a load in and from an oven, without addition of rotation system on an elevator and without organ movement in a temperature environment high.
  • the subject of the invention is a method in accordance with that defined by claim 1.
  • the invention also relates to an installation for the implementation of the above process and in accordance with that described in claim 5.
  • This installation 1 comprises a bell furnace 2, i.e. an oven open down inside from which can be introduced, via an opening 4, and by vertical displacement, a load 6 formed by a part or a set of parts to be treated arranged on a support plate 8 ( Figure 4).
  • the oven 2 includes a sealed enclosure 10 associated with heating means 12, such as for example resistance ramps electric. Opening 4 can be closed with a plug 14 during processing operations.
  • studs are provided or three retaining brackets 16 (only two of which are visible in Figures 1a-1c and 2a-2c). These studs 16 protrude radially from the inner wall of the enclosure 10.
  • the studs 16 give the opening 4 a indented outline, circular in the example shown ( Figure 2b).
  • These studs 16 are intended for support the support plate 8 provided with the load 6, in particular between the processing operation (s) when the oven is open ( Figure 1c). Indeed, when the oven 2 is closed by the plug 14, the support plate 8 is preferably raised above the studs 16 by feet of support 18 integral with the plug, in order to avoid creep studs 16 under the weight of the load 6.
  • these studs 16 can be arranged at another level of the inner wall of the enclosure 10.
  • the installation also includes means conventional load loading and unloading 6 in and from the oven 2, which can be made by a manipulator robot 20.
  • This robot 20 has an arm 22 which can be moved vertically along a column of guidance, not shown, by lifting means comprising for example a transmission system by chain and cogwheels, driven by a gear motor.
  • the plug 14 rests on the arm 22.
  • the oven 2 is mounted mobile and can be moved in translation in an X-Y direction from a first position called loading / unloading shown in the figure 1a, towards a second so-called anchoring position shown in Figure 1b.
  • the installation includes a guideway formed by two parallel rails 24 on which can move said oven 2 via of rollers 26.
  • the oven 2 can be moved in translation on this path through means M drive formed for example of a gear motor training in a classic way, in response to means of control, a pinion meshing with a rack (not shown).
  • the oven 2 rests on the rails 24, but it is understood that according to a variant not shown, the oven 2 can be suspended from a support structure, such as a gantry, by through pebbles and one or more tracks guides placed above and / or on the sides of the oven 2.
  • a support structure such as a gantry
  • the installation shown here also includes ( Figures 2a to 2c) a cooling tank 28 in which the load 6 is intended to be quenched, this tank 28 comprising autonomous transfer means 30 for the unloading of the load 6 from the oven 2 to the tank 28.
  • These autonomous transfer means 30 include also an arm which can be moved vertically along a guide column, not shown, by means lift of the same type as those described in connection with the lifting means 20 of Figures 1a to 1c.
  • the support plate 8 has the shape of a rigid flat honeycomb grid 32 having at its periphery notches 34 the number of four in the example shown.
  • Grid 32 shows thus a substantially complementary contour and dimensions slightly smaller than that of opening 4 so that grid 32 can pass during loading and unloading through the opening 4.
  • the arm 22 is raised by actuating the means elevators, to bring the load into enclosure 10 of the oven 2.
  • the support plate 8 will have been placed on feet 18 in an angular position such that the notches 34 are aligned with the retaining studs or consoles 16.
  • the load 6 and the support plate 8 are brought to a level higher than that of the studs 16 constituting the anchoring means. In this position, the charge 6 and the support plate 8 are in the position of loading unloading.
  • the oven 2 moves for the quenching operation above the cooling tank 28, this tank 25 being fixed.
  • the loading and unloading positions are therefore offset.
  • the bin 28 can be mounted mobile and come position under the oven 2, so that the operations of loading and unloading are carried out in the same position. So we qualify here as position of loading / unloading a position in which can carry out the two operations mentioned above or one of these operations.
  • the plug 14 can be omitted so that the load rests directly on arm 22.
  • the processing station 2 is formed by an oven, but it will be understood that this station could be formed by any other type of station such as a drip station.
  • the installation can in addition to having several ovens in the upper position and / or drip stations and in the lower position multiple cooling stations or other elements of a conventional heat treatment installation.
