Definitions
- the invention relates to a loading device, or tool, for supporting parts in a heat treatment furnace.
- a particular, but not exclusive, field of application of the invention is that of tools for supporting parts in a furnace of cementation.
- thermostructural composite material instead of a material metal, to make soles of heat treatment furnaces.
- Several soles may be provided spaced apart from each other other by spacers also made of a composite material thermostructural.
- the composite material used is a composite material carbon-carbon (C-C) or a ceramic matrix composite material (CMC).
- this known loading device does not prove adapted to achieve optimal loading, as can be desired when a relatively large number of identical must be treated.
- this device does not lend itself to robotization loading and unloading operations.
- US-A-1,813,085 shows a similar device made of refractory material.
- the present invention aims to overcome the disadvantages aforementioned devices of the prior art and proposes for this purpose a loading device made essentially of composite material thermostructural comprising: a pedestal, a partition rising above of the base and including, for example, amounts between which cross members, and a plurality of support arms attached to the partition and extending substantially horizontally therefrom up to their free ends, the arms being arranged substantially symmetrical on both sides of the partition, so that to be treated can be supported cantilevered by said arms.
- the loading device because of its realization in Thermostructural composite material and the presence of horizontal arms having a free end, offers positional accuracy and accessibility required for robotizing loading operations and unloading of the parts to be treated.
- composite materials thermostructural materials such as C-C composites and CMCs are characterized by their dimensional stability and flexural strength, this one authorizing the loading of the parts in cantilever.
- such a device can be made lightly and aerated, while offering a great filling capacity. It is therefore easy to handle, offers a great ability to exchange with parts to be treated, particularly during carburizing or quenching operations, and has a high loading efficiency.
- pieces can be mounted on the support arms to materialize locations of parts to be treated. These can be slipped or hung on the support arms, when they have an internal passage, or may be suspended by leaning on two neighboring arms.
- the loading device 10 of FIG. particular for supporting annular pieces A, such as pinions gearboxes. Only a few A pieces are shown on the figure 1.
- the device comprises (FIGS. 1 and 2) a support structure formed essentially of a base or sole 12, a partition vertical 14 supported by the base 12, in the middle part thereof, lateral reinforcement gussets 16, 18 and horizontal support arms 20.
- the central partition 14 includes side posts 140, 142 between which horizontal sleepers extend 144.
- the arms of support 20 are formed by bars 22 which, in their central part, are supported by the sleepers 144.
- the bars 22 extend from and other of the partition 14, each forming two opposite opposed arms of same dimensions. At their end remote from the partition 14, the arms 20 are free.
- the horizontal support arms 20 may be screwed on the partition 14, on either side thereof.
- the arms are mounted substantially symmetrically with respect to the vertical plane median of the partition. This means that the arms are substantially same dimensions and in the same number on each side of the partition, but not necessarily exactly aligned two by two.
- the above constituent elements of the support structure are made of a thermostructural composite material.
- Composite materials that can be used are composite materials carbon / carbon (C / C) and matrix composite materials ceramic (CMC).
- C / C composites are obtained by carrying out a carbon fiber preform and densification of the preform by formation of a carbon matrix within its porosity.
- the matrix carbon can be obtained by liquid means, that is to say by impregnation of the preform by means of a liquid composition (such as a resin) carbon precursor and heat treatment to transform the precursor carbon, or gaseous, that is to say by chemical infiltration in the vapor phase.
- CMCs are obtained by making a preform fibers made of refractory fibers, for example carbon fibers or ceramic, and densification of the preform by forming a matrix ceramic within its porosity.
- the matrix ceramic for example silicon carbide (SiC) can be obtained by liquid or by chemical vapor infiltration.
- thermostructural composite materials lies in their excellent mechanical properties, especially their held in flexion.
- thermostructural composite materials lies in their great dimensional stability, even when exposed to strong temperature variations. This allows retain for the support arms 20 positional references practically invariable and therefore to have the precision required for the robotization of loading and unloading operations.
- the mode supporting parts A on the arms 20 also makes it possible to easy robotization.
- pieces A may be placed on the arm 20 side by side or at predetermined locations, these being for example materialized by notches formed on the arms.
- the posts 140, 142 have end portions 140 a, 142 a which engage in corresponding housings 12 a, 12 b formed in the base 12, while the crosspieces 144 have end portions 144 a, 144 b which engage in recesses such as 142 c, formed in the uprights 140, 142.
- housing 142 c may be provided at regular intervals along the uprights 140 , 142 in order to mount the sleepers 144 with an interval determined according to the size of the parts A in the vertical direction.
- the gussets 16, 18 have tangs 16a, 18a along their lower edges that engage in corresponding recesses 12 c, 12 d formed in the base 12.
- the posts 140, 142 are supported by gussets 16 , 18 by recesses 140 d , 142 d formed along their outer edges.
- Each rod 22 has in its central portion has a notch 22 which cooperates with a notch 144 c formed in a cross member 144 in order to achieve a recess of the bar on the crosspiece.
- Each crosspiece has notches 144 c distributed over its length to mount bars 22 on the same cross with a determined interval depending on the size of the parts A in the horizontal direction.
- the modular nature of the support structure can be completed by realizing each amount 140, 142 not in a single piece, but in several pieces assembled end to end.
- the amounts 140, 142 and cross members 144 of the partition 14 can be made in one piece for example by machining a plate of thermostructural composite material.
- Figure 1 shows that the loading device possesses a very large filling capacity while presenting a structure light and airy, recesses that can be practiced in elements of the structure such as the base 12 and the gussets 16, 18.
- the handling of the complete loading device is easy.
- the heat treatment includes the diffusion of gas at contact of the parts, the gas exchanges with the parts are facilitated.
- the loading device of Figure 3 differs from that of FIG. 1 in that it is more particularly intended for the support of elongate solid parts, such as B-shafts, which are arranged vertically (in FIG. 3, pieces B are shown only on a side of the loading device). In addition, parts locations B are materialized by pieces 26 on which the pieces rest.
- elongate solid parts such as B-shafts
- the construction of the reinforcing structure is identical to that of Figure 1, with the base 12 support of the central partition 14 on which are mounted the bars 22 forming the horizontal arms 20 having their ends free.
- the number of sleepers 144 of the partition between the uprights 140, 142, and the spacing between the sleepers are determined according to the vertical dimensions of the B parts.
- the mutual spacing between the arms 20 is determined according to the horizontal dimensions of rooms B.
- each piece B rests by a shoulder on two pins 26 carried by adjacent arms 20 in the same locations on these arms, each piece being introduced for its loading in the interval between two arms.
- the pieces 26 are distributed on along each arm with a mutual spacing depending on the footprint horizontal parts B, in the direction parallel to the arms 20.
- the pins 26 may be made of a composite material thermostructural, for example the same as that of the other elements of the support structure, or a refractory metal material.
- the 26 pieces may be in the form of spikes simply mounted slightly by force on the arms 20, without gluing.
- Figures 1 and 3 have shown loading supporting each of the identical parts, it goes without saying that pieces of different shapes may be arranged on the same device loading.
Description
- ils se cémentent et deviennent rapidement cassants, ce qui peut entraíner de graves désordres dans les fours ;
- ils doivent être massifs pour éviter des déformations trop importantes sous charge, déformations qui à leur tour pourraient entraíner des déformations des pièces supportées, nécessitant une rectification ultérieure et, par conséquent, une perte d'épaisseur de la couche cémentée ;
- des outillages massifs rendent plus difficiles les échanges gazeux et diminuent le rendement de chargement, c'est-à-dire la part de volume utile occupée par les pièces à traiter ;
- les chocs thermiques violents peuvent entraíner des déformations et ruptures du métal ; et
- les inévitables variations dimensionnelles d'origine thermique rendent impossible la robotisation des opérations de chargement et de déchargement des pièces et de manutention de l'outillage, en raison d'un défaut rédhibitoire de précision de position.
- la figure 1 est une vue schématique en perspective d'un premier mode de réalisation d'un dispositif de chargement conforme à l'invention ;
- la figure 2 est une vue éclatée montrant une partie des éléments du dispositif de chargement de la figure 1 avant leur assemblage mutuel; et
- la figure 3 est une vue schématique en perspective d'un deuxième mode de réalisation d'un dispositif de chargement conforme à l'invention.
