Description
PROCEDE <B>PERFECTIONNE</B> POUR FABRIQUER<B>DES</B> PIECES <B>ALLIAGE</B> LEGER L'invention se rattache au secteur technique<B>de</B> la fabrication pièces en alliage léger, notamment en aluminium, obtenues en fonderie forgeage et procédés similaires. PROCESS <B> PERFECTED </ B> TO MANUFACTURE <B> PIECES <B> ALLOY </ B> LIGHT The invention relates to the technical sector <B> of </ B> manufacturing alloy parts lightweight, especially aluminum, obtained in foundry forging and similar processes.
On connaît, par le brevet EP <B>119.365,</B> un procédé spécifique dénommé COBAPRESS qui combine les techniques de fonderie de forgeage de pièces en aluminium ou alliages d'aluminium. Patent EP <B> 119.365, </ B>, discloses a specific process called COBAPRESS which combines the foundry techniques of forging aluminum or aluminum alloy parts.
On rappelle que ce procédé consiste<B>à</B> couler de l'aluminium ou alliage d'aluminium dans un moule et après la coulée,<B>à</B> démouler la pièce encore chaude dénommée préforme<B>à</B> une température de l'ordre de 400'C<B>à</B> <B>500'C,</B> on place entre deux matrices ou parties d'une matrice définissant une empreinte de dimensions légèrement inférieures<B>à</B> celles du moule qui correspondent<B>à</B> celles de la pièce finale, les deux coquilles ou parties étant fortement pressées l'une contre l'autre pour exercer sur la préforme coulée mise entre parties de matrices un effet combiné de pressage<B>à</B> c#ur de corroyage superficiel. It is recalled that this process consists of pouring aluminum or aluminum alloy into a mold and after casting, demolding the still hot part called preform B <B> at </ B> a temperature of the order of 400'C <B> to </ B> <500> C, </ B> is placed between two matrices or parts of a matrix defining a fingerprint of dimensions slightly smaller than those of the mold which correspond to those of the final piece, the two shells or parts being strongly pressed against each other to exert on the casting preform between parts of dies a combined pressing effect <B> to </ B> c # ur superficial wrought.
On connaît par ailleurs, par le brevet FR <B>2.778.125,</B> un procédé du type précite amélioré qui vise<B>à</B> profiter de l'opération de préchauffe pour réaliser-p- même temps l'opération de traitement thermique économisant ainsi sur l'opération de traitement thermique classique postérieure<B>à</B> l'opération de frappe. Entre la coulée de la préforme et le forgeage, on transfère ladite préforme coulée dans un four assurant la mise en solution de ladite preforme coulée<B>à</B> la température de mise en solution matériau constitutif et placée ensuite entre les deux parties de la matrice de frappe pour l'operation de forgeage avec refroidissement ambiant, cri accéléré ou trempé. Furthermore, patent FR <B> 2.778.125, </ B>, discloses a method of the above-mentioned improved type which aims to take advantage of the preheating operation to achieve the same time. the heat treatment operation thus saving on the conventional thermal treatment operation posterior <B> to </ B> the striking operation. Between the casting of the preform and the forging, transferring said cast preform in a furnace ensuring the dissolution of said casting preform <B> at </ B> the dissolution temperature constituent material and placed between the two parts punching die for the forging operation with ambient cooling, accelerated screaming or quenching.
Ce procédé amélioré dénommé COBAPRESS 2 permet donc de réduire temps de production et le coût de fabrication manière significative des pièces, tout en obtenant les mêmes caractéristiques des pièces rapport<B>à</B> l'enseignement du procédé COBAPRESS décrit dans<B>le</B> brevet<B>119.365.</B> mise en #uvre du procédé précité dans les deux versions requiert de manière courante dans l'activité<B>de</B> forgeage de pulvériser sur matrice de forge une solution eau plus graphite<B>à</B> l'état liquide, qui a pour but de faciliter le fluage de la matière ainsi forgée et le démoulage la pièce finale. This improved process known as COBAPRESS 2 thus allows to reduce production time and the cost of manufacturing significantly the parts, while obtaining the same characteristics of the parts report <B> to </ B> the teaching of the COBAPRESS process described in <B The <119.365 patent. </ B> </ B> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> <BR> a water solution with graphite <B> to </ B> the liquid state, which aims to facilitate the creep of the material thus forged and demolding the final piece.
En pratique, la pulvérisation de la solution graphite sur la matrice de forge est une opération qui, en fonction de la complexité des formes de la pièce finale brute, est relativement longue et coûteuse, qui ne permet pas systématiquement d'avoir une homogénéité<B>de</B> pulvérisation dans les parties d'accès difficile de la pièce, et enfin qui est très salissante pour le poste de travail. In practice, the spraying of the graphite solution on the forge matrix is an operation which, depending on the complexity of the forms of the final final part, is relatively long and expensive, which does not systematically allow homogeneity <B Spraying in parts difficult to access the room, and finally is very messy for the workstation.
Le but recherché selon l'invention était donc d'assurer une optimisation du procédé COBAPRESS initial de coulé-forgé en alliage léger. The aim of the invention was therefore to optimize the COBAPRESS initial cast-forged light alloy process.
Une première démarche a été de s'orienter sur une amélioration des conditions de dépose du graphite dans la matrice de forgeage par pulvérisation de la solution de graphite sur la matrice de forge, ec un meilleur contrôle de la distribution<B>à</B> l'aide de robots. En pratique, cette solution est peu satisfaisante, car elle nécessite tout de même l'intervention de l'homme, et les coûts et problèmes environnementaux sont toujours<B>là.</B> La démarche du demandeur s'est donc orientée de manière inattendue sur une autre possibilité qui s'intercale entre les deux phases principales de coulée et de forgeage, possibilité qui offre toutes les garanties dans une répartition homogène de la solution graphite sur la préforme, qui au surplus apporte des caractéristiques particulières intéressantes, en améliorant productivité du procédé. A first step was to focus on improving the graphite deposition conditions in the forging matrix by spraying the graphite solution onto the forge matrix, and better controlling the distribution <B> to </ B > the help of robots. In practice, this solution is unsatisfactory, because it still requires human intervention, and the environmental costs and problems are always <B> there. </ B> The applicant's approach was therefore oriented Unexpectedly on another possibility which is inserted between the two main phases of casting and forging, possibility which offers all the guarantees in a homogeneous distribution of the graphite solution on the preform, which in addition brings interesting particular characteristics, by improving process productivity.
