Description
Domaine technique de l’inventionTechnical field of the invention
L’invention concerne le traitement de pièces métalliques.The invention relates to the treatment of metal parts.
Etat de la techniqueState of the art
Dans certains domaines techniques, comme par exemple celui des véhicules (éventuellement automobiles), on effectue sur certaines pièces métalliques des traitements destinés à réaliser un dépôt d’une première matière sur une première zone d’une première face. Par exemple et non limitativement, ce dépôt peut se matérialiser sous la forme d’un cordon de soudure.In certain technical fields, such as for example that of vehicles (possibly automobiles), treatments are carried out on certain metal parts intended to deposit a first material on a first zone of a first face. For example and non-limitingly, this deposit can materialize in the form of a weld bead.
Parfois, avant de faire l’objet d’un dépôt de première matière, la pièce métallique a préalablement fait l’objet d’un traitement anticorrosion par cataphorèse avec une seconde matière, comme par exemple du zinc. Or, lors du dépôt de la première matière dans une première zone d’une pièce métallique, la première température à laquelle est chauffée cette première zone peut provoquer dans cette dernière un endommagement, voire une suppression, de la seconde matière anticorrosion préalablement déposée lorsque la seconde température de fusion de cette seconde matière anticorrosion est strictement inférieure à la première température de fusion. Par exemple, lorsque la pièce métallique est en acier sa première température de fusion est égale à environ 1500°C, alors que la seconde température de fusion du zinc est égale à environ 420°C.Sometimes, before being the subject of a deposition of the first material, the metal part has previously been the subject of an anti-corrosion treatment by cataphoresis with a second material, such as for example zinc. However, during the deposition of the first material in a first zone of a metal part, the first temperature to which this first zone is heated can cause in the latter damage, or even elimination, of the second anti-corrosion material previously deposited when the second melting temperature of this second anti-corrosion material is strictly lower than the first melting temperature. For example, when the metal part is made of steel, its first melting temperature is equal to approximately 1500°C, whereas the second melting temperature of zinc is equal to approximately 420°C.
En présence d’un tel endommagement ou d’une telle suppression, on est contraint d’effectuer des retouches anticorrosion ultérieurement et avec une installation de traitement qui est notablement différente de celle initialement utilisée pour réaliser le traitement anticorrosion initial du fait qu’elle n’a plus à réaliser de nombreuses sous-étapes d’un traitement anticorrosion complet indispensables pour une pièce métallique « brute ». La nécessité d’utiliser deux installations de traitement anticorrosion dans deux postes différents augmente les coûts de fabrication des systèmes comprenant les pièces métalliques traitées, mais aussi augmente le nombre d’opérations devant être supervisées par des techniciens, ce qui augmente encore plus les coûts de fabrication. Par ailleurs, certaines retouches anticorrosion ne peuvent être réalisées qu’une fois les pièces métalliques traitées et conformées (par exemple par découpe et/ou emboutissage), voire assemblées à d’autres pièces métalliques. Or, certaines zones traitées et devant être retouchées peuvent se retrouver placées dans ce que l’homme de l’art appelle des « corps creux » où elles sont inaccessibles à l’installation de retouche anticorrosion.In the presence of such damage or such removal, one is forced to carry out anti-corrosion touch-ups later and with a treatment installation which is notably different from that initially used to carry out the initial anti-corrosion treatment because it does not You no longer have to carry out many sub-steps of a complete anti-corrosion treatment that are essential for a "raw" metal part. The need to use two anticorrosion treatment facilities in two different positions increases the manufacturing costs of the systems comprising the treated metal parts, but also increases the number of operations that must be supervised by technicians, which further increases the costs of manufacturing. Furthermore, certain anti-corrosion touch-ups can only be carried out once the metal parts have been treated and shaped (for example by cutting and/or stamping), or even assembled with other metal parts. However, certain areas treated and needing to be touched up may find themselves placed in what those skilled in the art call “hollow bodies” where they are inaccessible to the anti-corrosion touch-up installation.
L’invention a donc notamment pour but d’améliorer la situation.The aim of the invention is therefore in particular to improve the situation.
Présentation de l’inventionPresentation of the invention
Elle propose notamment à cet effet un procédé de traitement destiné à traiter une pièce métallique comprenant des première et seconde faces opposées.It proposes in particular for this purpose a treatment method intended to treat a metal part comprising first and second opposite faces.
Ce procédé de traitement se caractérise par le fait qu’il comprend une étape dans laquelle on réalise un dépôt d’une première matière sur une première zone de la première face au moyen d’un premier dispositif ayant une trajectoire choisie, puis on dépose au moins sur cette première zone une couche de seconde matière anticorrosion au moyen d’un deuxième dispositif suivant cette trajectoire avec un décalage temporel choisi.This treatment method is characterized in that it comprises a step in which a first material is deposited on a first zone of the first face by means of a first device having a chosen trajectory, then less on this first zone a layer of second anti-corrosion material by means of a second device following this trajectory with a chosen time lag.
Ainsi, on peut avantageusement effectuer une retouche anticorrosion dans chaque première zone venant de faire l’objet d’un premier dépôt au cas où la protection anticorrosion préalablement réalisée aurait été dégradée ou supprimée par ce premier dépôt.Thus, an anti-corrosion touch-up can advantageously be carried out in each first zone which has just been the subject of a first deposit in the event that the anti-corrosion protection previously carried out has been degraded or eliminated by this first deposit.
Le procédé de traitement selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :The treatment method according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- dans son étape on peut effectuer un refroidissement d’au moins une sous-partie de la première zone avant de déposer la couche anticorrosion sur cette sous-partie refroidie ;- in its step, at least a sub-part of the first zone can be cooled before depositing the anti-corrosion layer on this cooled sub-part;
- en présence de la première option, dans son étape on peut refroidir de façon continue la première zone par un déplacement continu du deuxième dispositif, avant de déposer la couche anticorrosion de façon continue ;- in the presence of the first option, in its step, the first zone can be cooled continuously by continuously moving the second device, before depositing the anti-corrosion layer continuously;
- dans son étape on peut déposer sur une seconde zone de la seconde face, située sous la première zone, une autre couche de seconde matière anticorrosion au moyen d’un troisième dispositif couplé en déplacement au deuxième dispositif afin de suivre la trajectoire avec le décalage temporel choisi ;- in its step, it is possible to deposit on a second zone of the second face, located under the first zone, another layer of second anti-corrosion material by means of a third device coupled in displacement to the second device in order to follow the trajectory with the offset time chosen;
- en présence de la dernière option, dans son étape on peut effectuer un refroidissement d’au moins une sous-partie de la seconde zone avant de déposer l’autre couche anticorrosion sur cette sous-partie refroidie ;- in the presence of the last option, in its step, at least a sub-part of the second zone can be cooled before depositing the other anti-corrosion layer on this cooled sub-part;
- en présence de la dernière sous-option, dans son étape on peut refroidir de façon continue la seconde zone par un déplacement continu du troisième dispositif, avant de déposer l’autre couche anticorrosion de façon continue.- in the presence of the last sub-option, in its step, the second zone can be cooled continuously by continuously moving the third device, before depositing the other anti-corrosion layer continuously.
L’invention propose également une installation de traitement destinée à traiter une pièce métallique comprenant des première et seconde faces opposées.The invention also proposes a treatment installation intended to treat a metal part comprising first and second opposite faces.
Cette installation de traitement se caractérise par le fait qu’elle comprend un premier dispositif propre à se déplacer sur une trajectoire choisie par rapport à la pièce métallique afin de réaliser un dépôt d’une première matière sur une première zone de sa première face, et un deuxième dispositif propre à se déplacer sur la trajectoire choisie par rapport à la pièce métallique afin de déposer une couche de seconde matière anticorrosion sur cette première zone, avec un décalage temporel choisi par rapport au dépôt de la première matière.This treatment installation is characterized in that it comprises a first device capable of moving along a chosen path relative to the metal part in order to deposit a first material on a first zone of its first face, and a second device capable of moving along the chosen trajectory relative to the metal part in order to deposit a layer of second anti-corrosion material on this first zone, with a chosen time lag relative to the deposition of the first material.
L’installation de traitement selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment :The treatment installation according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- son deuxième dispositif peut être propre à refroidir au moins une sous-partie de la première zone avant de déposer la couche anticorrosion sur cette sous-partie refroidie ;- Its second device can be suitable for cooling at least a sub-part of the first zone before depositing the anti-corrosion layer on this cooled sub-part;
- elle peut comprendre un troisième dispositif couplé en déplacement au deuxième dispositif pour suivre la trajectoire par rapport à la pièce métallique avec le décalage temporel choisi, afin de déposer une autre couche de seconde matière anticorrosion sur une seconde zone de la seconde face, située sous la première zone ;- it may comprise a third device coupled in displacement to the second device to follow the trajectory relative to the metal part with the chosen time lag, in order to deposit another layer of second anti-corrosion material on a second zone of the second face, located under the first area;
- en présence de la dernière option, son troisième dispositif peut être propre à refroidir au moins une sous-partie de la seconde zone avant de déposer l’autre couche anticorrosion sur cette sous-partie refroidie.- in the presence of the last option, its third device can be suitable for cooling at least a sub-part of the second zone before depositing the other anti-corrosion layer on this cooled sub-part.
