Definitions

  • the present invention relates to a thermal treatment installation.
  • extensions 4c which, in a second angular position characteristic of the plate 2 (FIGS. 2a and 2b) can overlap and overlap the retaining studs 4a to rest in simple support on them, so allow the mounting of the support plate 2, by its own weight, in the oven chamber 1.
  • a load support base 20 on which can come to rest in support, by its own weight, the support plate 2 accompanied by the load C.
  • the base 20 comprises a body 22 which is engaged and guided in rotation in the arm 10 and from which extends radially, to project, a lever 24 carrying at its free end a coupling member formed, in this exemplary embodiment, by a coupling ring or eyelet 26.
  • the base 20 and the coupling ring 26 can, under the action of the lifting means 8, move vertically inside the lower cell 6 forming a tray, to occupy characteristic vertical positions, called low (reference B) and high (reference H), positions which are shown respectively in solid lines and in broken lines in Figure 3a.
  • the low position B is that in which the quenching of the load C is carried out
  • the high position H is that in which the load C is locked or unlocked in the cell upper 1, to perform the anchoring operations mentioned above ( Figures 1a, 1b and 2a, 2b).
  • the slides 28 are formed by elongated cylindrical grooves, which are open along their length towards the inside of the skirt 30, and whose inner shape is shaped to receive with play the ring d hitch 26.
  • the slides 28 which are housed integrally in the quench tank 6 are shaped so that they release the coupling ring 26 when this ring is in its highest position H. In this position, the coupling ring 26 can engage on the movable finger 34 and it can then be moved transversely under the control of the actuator 32, from one of the positions, for example G, to the other position, in this case the position D.
  • the means for guiding in translation of the base 22 maintain this base in two characteristic angular positions G and D, when this base translates between its two high H and low B positions, to ensure the correct angular positioning of the load support plate 2 and its passage through the inlet of the oven 1; these guide means releasing the base 22 in its highest position H, in order to allow its rotation, and therefore the locking and unlocking of the support plate 2 in the oven 1.
  • the actuator here marked with the references 42 and 52, is arranged laterally, respectively on the front (FIGS. 4a and 4b) or on the side of the tray ( Figure 5).
  • the slides here referenced 48, are formed by U-shaped rails which are integral with the recirculation skirt 30, and in which can be accommodated a movable finger 44 mounted at the free end of the lever 24.
  • the movable finger 44 is associated with a guide roller 50 which is mounted free in rotation at the free end of the lever 24 and which is oriented so as to be able to roll in the rails 48 during movements of lifting and lowering of the base 22.
