Definitions
- the present invention relates to a support for supporting a piece, in particular a metal part, during a treatment thermal of said room in an oven.
- the heat treatment is a cementation treatment with low pressure of a steel part using, for example, gas, oil, etc.
- Patent Application FR-A-2 772 467 discloses a device for supporting parts to be thermally treated in an oven, comprising trays on each of which are mounted groups of metal pegs. Each group of metal pegs serves as support a piece to be treated in the form of a pinion. The trays are designed to can be superimposed vertically.
- the loading of the pieces on the trays and the Overlay trays are performed by a robot.
- the robot presents the piece above the group of pawns, then the coward.
- the present invention aims in the first place to provide support which improves the efficiency of loading a part to be treated thermally.
- a support is provided to support the less in part; a part during a heat treatment of said part, comprise a guiding element allowing guide the workpiece towards a surface or part of a support surface of said support when it is put in place on the support.
- the expression “at least in” means that the support according to the invention can be used to completely support the part, or, alternatively, to partially support only said part.
- the support effort is shared between the support according to the invention and one or more other supports, preferably identical to the support according to the invention.
- the guide element of the support according to the invention facilitates the setting up of the part to be treated, especially when this setting up is robotic, and compensates for a possible inaccuracy of the robot.
- the guide element consists of an elongated element extending from a base of the support substantially perpendicularly at this base and having an end portion, opposite the base, warhead shape. More particularly, the guiding element can include a stem terminated by a head, the head constituting the said end portion in the shape of an ogive.
- the stem has a diameter less than that of the head.
- the end of the guide element opposite the base is rounded.
- the support according to the invention is characterized in that it comprises a body metal part, of which the guide element may be part, and an element ceramic embedded in the metal body and defining said support surface.
- a heat treatment operation of the part for example type carburizing (especially when the piece is in steel), can be carried out without the support surface and the part being stick to each other. Unloading the part, once the treatment finished, is thus facilitated.
- the fact of embedding the ceramic element in a metal body allows to increase the impact resistance of the ceramic. It is thus possible to previously load the part to be treated by placing this piece on top of the holder and then releasing it, all at medium of a robot, and with a reduced risk of breakage of the ceramic.
- the ceramic element can be mounted in the metal body so that it can be easily replaced.
- the ceramic element can be crimped into the body metallic, simply placed in a recess of the metal body without to be fixed, or placed in a recess of the metal body and retained in this recess by one or more point (s) of solder or solder formed on or near an upper edge of the recess.
- the ceramic used in the present invention is mullite. This material presents indeed a good mechanical resistance.
- the ceramic element is embedded in the metal body with a clearance allowing the ceramic element and the metal body to expand freely.
- the element ceramics is enshrined in a base of the metallic body constituting the aforementioned base of the support.
- the ceramic element can thus consist of an annular piece having an axis of symmetry common with the element of guide.
- the support surface is inclined, or comprises an inclined part to prevent lateral movement of the workpiece when it rests, at least in part, flat on the support.
- the support surface is shaped to ensure contact only in one or more discrete points with a directory part when such an annular piece rests, at least in part, flat on the support.
- the support surface may have, for example, a shape frustoconical, or be in the form of a surface part spherical.
- the element ceramic is enshrined in the end part of the element of guide.
- the support according to the invention can be present in the form of a pawn.
- the support according to the invention furthermore typically comprises fastening means to a support plate.
- Such fixing means may comprise a projection of the support, intended to be introduced into a corresponding ferry hole from the support plate, from a first end of this hole, and comprising a thin frustoconical portion adapted to cooperate with a chamfer provided at a second end, opposite to the first, of the hole ferry.
- the present invention also relates to equipment for support comprising a support plate and at least one support such as defined above, mounted on the support plate.
- the support plate is preferably made of a material thermo-structural composite, such as a carbon-carbon composite material.
- the or each support, and more particularly the body metal of the latter, is advantageously mounted on the plate of support by crimping and with a game.
- the point of intersection between an axis of symmetry the or each support and the plane of a surface of the support plate receiving the or each support is substantially coincident with the vertex cone defined by an outer surface of the thin frustoconical portion.
- the equipment of support according to the invention comprises at least one group of three supports arranged in a triangle.
- the present invention further aims at providing a method of heat treatment of a metal part which facilitates durable, the unloading of the part after the heat treatment.
- a heat treatment process is provided of a metal part, characterized in that one uses, to support said part, at least one support having a ceramic surface, of preferably in mullite, on which at least a part of said room.
- the metal part is in contact with the ceramic surface only in one or more discrete points.
- the treatment thermal consists of a carburizing operation of a steel part.
- support equipment for the treatment of a metal part, such as the cementation of a piece of steel, includes a support plate 1 and supports in the form of pins 2 mounted on the support plate 1.
- the pawns 2 are grouped by three. In each group of pions (only one group is shown in Figure 2), the pins 2 are arranged in a triangle, preferably in equilateral triangle.
- the support plate 1 is of preferably made of a thermo-structural composite material, such as a carbon-carbon composite material. Alternatively, however, it can be designed in metal.
- Each peg 2 comprises a metal body 20 constituted a projecting lower part 21 housed in a cylindrical hole corresponding 10 of the support plate 1, and an upper part 22 extending beyond the upper surface, designated 11, of the support plate 1, and perpendicular to this surface.
- the body 20 is preferably monolithic.
- each pin 2 is fixed to the support plate 1 by crimping.
- the lower part 21 has, at its lower end, a thin frustoconical portion 210 cooperating with a chamfer 12 practiced on the lower edge of the ferry hole 10.
- the support equipment according to the invention is assembled by presenting each pawn 2 over the ferry hole corresponding 10, then introducing the lower part 21 into the hole 10, down, until the frustoconical portion 210 come cooperate with chamfer 12.
- each peg 2 comprises a base 220 in skirt shape that rests on the upper surface 11 of the plate of support 1, and a central and elongated guide member 221 extending perpendicular to the support plate 1 and the 220 based since the upper end of the base 220 along an axis of symmetry AS1 of pawn 2.
- the base 220 is cylindrical at the bottom, and frustoconical in the upper part. It further comprises a recess in which is housed a ceramic element 23 in the form of a annular pellet having a frustoconical upper surface 230.
- the ceramic chip 23 is more particularly crimped to the base 220, by cooperation between a chamfer practiced on the upper outer edge of the pellet 23 and a projection 222 of an annular edge 223 of the base 220.
- ceramic chip 23 can nevertheless be mounted differently in the recess of the base 220. It can for example simply be asked in this recess, without being crimped or otherwise fixed, in order to facilitate its replacement in case of breakage. It can also be placed in the recess and retained in it simply by one or several point (s) of solder or solder 224 formed on or near an upper edge of the recess, as shown in Figure 3.
- the frustoconical upper surface 230 of the pellet in ceramic 23 is flush with the upper face of the base 220, so that it can serve as a support surface, and is arranged so that the vertex (not shown) of the cone defined by this surface is directed towards the upper end of the pin 2, along the axis AS1.
- the guide element 221 comprises a rod 225 which is complete, its upper end, opposite the base 220, by a head 226.
- the shape of the head 226 is chosen to allow effective guidance during the positioning of a workpiece on the pawn 2.
- the head 226 has a shell or warhead shape, preferably an ogival shape as illustrated in the figures.
- the upper end 226a the head 226 is rounded rather than pointed.
- the diameter of the rod 225 is smaller than that of the head 226.
- each pin 2 is arranged by plate 1 so that the point of intersection, designated at the FIG. 1 by the reference O, between the axis of symmetry AS1 of the pin 2 and the plane defined by the upper surface 11 of the plate 1 is substantially confused with the top of the cone defined by the surface external (in contact with the chamfer 12) of the thin frustoconical part 210.
- a slight clearance 211 may be provided between the outer face of the protruding bottom portion 21 of each pin 2 and the inner face of the hole 10 corresponding.
- the differential dilations between the ceramic chip 23 and the metal body 20 of each pin 2 can be absorbed by a slight lateral play 231 between the faces inside and / or outside of the pellet 23 and the wall or walls corresponding to the annular recess of the body 20.
- annular metal part 3 with heat treatment such as a pinion, is placed flat on a group three pins 2 so as to bear against the frustoconical surfaces in 2.
- the expression "flat” means that the axis of symmetry (designated by the mark AS2) of the annular piece 3 is perpendicular to the support plate 1 or, in other words, parallel to the axis of symmetry AS1 of each pin 2.
- the contact between the piece 3 and each of the ceramic support surfaces 230 is punctual.
- the piece 3 is thus supported by the support equipment 1, 2 according to the invention in three discrete points A, B and C.
- the guide elements 221 fit within the inner surface 30 of the piece 3 and are away from this internal surface, that is to say that they do not enter any place in contact with the room 3. Thanks to the inclination of the support 230, the part 3 is well maintained on the pins 2 under the effect of gravitation: In particular, piece 3 can not move laterally to come into contact with the guide elements 221.
- the establishment of the piece 3 on the pawns 2 is preferably performed by means of a robot, which places the piece 3 above the pieces 2 and then the coward so that she falls on them.
- the piece 3 is guided by the respective warhead-shaped heads 226 of the elements of 221. Due to the difference in diameter between rods 225 and heads 226 (the rods 225 are narrower than the heads 226), the piece 3, after having been guided by the heads 226, is no longer in contact with the guiding elements 221. This facilitates the fall of the piece 3 towards the support surfaces 230.
- each pawn 2 is encased in the metal body 20, that is to say is mounted in a recess of the body 20, increases the impact strength of the pellet 23. Therefore, the risk of breakage of the ceramic when piece 3 arrives in contact with the pins 2 is reduced.
- the latter is designed in mullite.
- the assembly consisting of support equipment 1, 2 and part 3 is placed in an oven such as a carburising reactor (not shown), where piece 3 undergoes heat treatment.
- an oven such as a carburising reactor (not shown)
- piece 3 undergoes heat treatment.
- the piece 3 can be removed without difficulty from the support equipment 1, 2 since, thanks to the ceramic material constituting the support surfaces 230 in direct contact with the metal part 3, the piece 3 and the pieces 2 will not be glued to each other.
- the annular piece 3 and the pins 2 are arranged so that the guide elements 21 are inscribed in the central empty space of room 3 delimited by inner annular surface thereof.
- the guide elements 221 are located beyond the outer annular surface of the part 3.
- the 3 is not necessarily annular, but may also be cylindrical.
- FIG. 5 also shows, by way of example, pions of support 2 according to the invention supporting an elongated vertical piece 4 in piston shape. Although only two pawns 2 are represented at the figure 5, we use at least three to ensure a good maintenance of the room 4.
- Figure 6 shows another type of configuration, in which each pawn 2 supports completely, and not only partially as in the arrangements of Figures 1 to 5, a metal part annular 5.
- the axis of symmetry of the annular piece 5 is thus confused with the axis AS1 of the pion 2.
- FIG. 7 shows a pawn 2 according to the invention supporting completely a part 6 in the form of a piston comprising a part lower ring 60.
- each ceramic support surface 230 can have slight bosses in places intended to define points of contact with the piece 5, 6.
- the invention is not limited to a particular form for the surfaces of ceramic support 230, and that there are many ways of conform these surfaces so that they each ensure a contact only in one or more discrete points with an annular piece when such an annular piece rests flat, completely or in part, on the corresponding pawn.
- FIG. 8 shows, by way of example, a second mode of embodiment of the invention, wherein each pin 2 '(only one pin 2' is shown in Figure 8) has a ceramic support surface 230 'shaped spherical surface portion.
- FIGS. 9 and 10 represent pions of support 7 and 8 according to a third embodiment of the invention.
- the pions 7, 8 differ from the pawns 2, 2 'essentially in that their element ceramic is embedded in the head of the guide element, rather only in the base of the metallic body (see the markers 70 and 80).
- the element ceramic 70 (respectively 80) has a support surface rounded 71 (respectively 81) on which can come to rest a piece.
- the ceramic elements 70 and 80 are simply laid, without being fixed, in a recess of the head of the element of guidance, so that they can be replaced easily in case of breakage. Alternatively, they can nevertheless be crimped into the recess or blocked by one or more solder points in a manner comparable to the example of Figure 3.
- the pins 7, 8 can be used, for example, as illustrated in Figure 11.
- a group of three support pieces of the type of pins 7 or 8 supports, in three points of contact, a metal part 72 having an annular lower part and a cylindrical upper solid part.
- the contact between room 72 and the pins 7 or 8 is between a metal bearing surface 73 of the piece 72 and the ceramic surface 71 or 81 of each peg.
- the implementation of the piece 72 on the pins 7 or 8 is facilitated by the guide elements.
- Figure 12 illustrates a support pin 9.
- the pawn 9 consists of a body 90 and a ceramic coating layer 91 covering the head of a guide element of the metal body 90 and attached to this head for example by gluing or brazing, as represented at the level of reference 92.
- the element ceramic 91 is not encased in the metal body.
- pion 9 can also be used to support a metal part to heat treatment, such as a piece of steel to be cements, by example in the manner illustrated in Figure 11 for pins 7, 8.
