Definitions

  • the invention relates to support and handling assemblies for heat treatment in groups of mechanical parts such as shafts or axes.
  • the most commonly used heat treatment assemblies are of two types: a first type where the parts are placed and guided, and a second type where the parts are suspended.
  • the assemblies of the first type consist of a base plate for handling comprising columns on which are mounted a lower grid and an upper grid separated by tubular spacers surrounding the columns, each part being supported by a support interlayer being mounted in one of the housings of the lower grid, and guided at its upper part by a guide insert being mounted in a similar orifice of the upper grid.
  • the second type assemblies include the same elements as those of the first type, except the lower grid and the guide spacers, the support spacers being of a special type and mounted in the upper grid.
  • the object of the invention is to eliminate the above drawbacks, that is to say to produce an assembly which, like the previous ones, ensures the vertical positioning of the parts to avoid deformations during processing, but which is entirely at the same time as light as possible while grouping the maximum number of parts in order to maximize the payload as well as the number of parts to be treated per load, which favors the cooling conditions during quenching by good passage of fluids, which is highly resistant to thermal shock and to the thrust forces of a pushing furnace, and which finally allows the positioning of the parts in a simple manner that can easily be automated.
  • the invention consists in making an assembly for the heat treatment of trees or axes in a vertical position comprising a monobloc assembly in the form of a plate which combines both an upper stage formed of support orifices, possibly on several alternating levels, for direct support and centering of the lower end of the parts, these orifices being joined by horizontal ribs, a lower stage also formed of orifices and ribs, and vertical pillars joining these ribs from one and the other stage, while leaving large openings for the circulation of fluids .
  • the parts 1 to be treated are assumed to be gearbox shafts 2 comprising several pinions 3 formed in one piece with the shaft 2, this type of part being particularly difficult to treat.
  • the invention would apply a fortiori to elongated parts of simpler shape and less bulky.
  • the single assembly 4 in the form of a two-stage tray 5 and 6.
  • the upper stage 5 comprises a number of orifices 7 each surrounded by a tubular sleeve 8, these various sleeves 8 and orifices 7 being arranged in a two-dimensional network and joined together by ribs 9 in at least two directions.
  • Each orifice 7 is intended to receive a cylindrical lower part 10 of one of the parts 1 which is supported by a conical or planar part on the upper edge of the corresponding sleeve 8.
  • the lower stage 6 also consists of orifices 11 surrounded by cylindrical sleeves 12 themselves joined by ribs 13, preferably also in the two directions. Special framing ribs 9a surround the entire upper stage 5, and in the same way special ribs 13a surround the entire lower stage 6.
  • a series of vertical pillars 14 join two by two of the ribs such as 9 or 9a of the upper stage and ribs such as 13 or 13a of the lower stage.
  • all these ribs and these pillars allow large openings 15 to exist between them, serving both to ensure the free circulation of the heating and then cooling fluid, and at the same time to lighten the part while retaining high resistance.
  • the whole of the plate 4 is made in one piece, which can be easily obtained for example in foundry using an alloy with high resistance to thermal shock.
  • the holes 7 and the sleeves 8 of the upper plate are arranged on two alternating levels, such as 8a and 8b, in order to avoid, as seen in Figures 2 and 3 , the interference between the gears 3 of larger diameter in order to reduce the center distance of the orifices 7 and consequently increase the load per plate.
  • the assembly is relatively simple and light, especially with regard to the weight of supported parts, while improving the quality of the parts by an excellent resistance which prevents the shocks of the parts between them during treatment and during loading.
  • the loading of the parts is done in an extremely simple manner, since it suffices to bring each part in front of the corresponding orifice 7 and to introduce it there by simple vertical axial translation, which is easily achievable by a manipulator arm.
  • the weight of supported parts can be relatively high, especially with the second embodiment.
  • the invention makes it possible, if desired, to superimpose two or more similar trays for simultaneous heat treatment, by stacking these trays, once loaded with their parts, on top of each other by means of stepped columns such as shown at 16 in FIG. 2, each of these columns having for example an X section with a cylindrical lower end 17 with base 18 and an upper end 19 which can also be X section and include a stop base 20.
  • the ends 17 and 19 can be mounted in additional holes provided for this purpose, for example in the corners of each plate 4. This latter arrangement further improves the density of the load, therefore the productivity of the treatment.
