PROCEDIMIENTO PARA LA APORTACIÓN DE MATERIALES METÁLICOS  PROCEDURE FOR THE CONTRIBUTION OF METAL MATERIALS
D E S C R I P C I Ó N CAMPO TÉCNICO DE LA INVENCIÓN D E S C R I P C I O N TECHNICAL FIELD OF THE INVENTION
La presente invención se refiere a un procedimiento para la aportación de material metálico sobre una determinada pieza y la posterior etapa de bruñido; así como el sistema de aportación de material metálico asociado a dicho procedimiento. La invención se encuadra en el sector técnico de los procesos de fabricación mediante aporte de material, aplicados tanto a piezas de revolución como de diferentes geometrías, y para materiales tales como aceros, aceros especiales, aleaciones base níquel y base titanio y otras aleaciones metálicas. ANTECEDENTES DE LA INVENCIÓN The present invention relates to a process for the provision of metallic material on a particular piece and the subsequent stage of burnishing; as well as the system of contribution of metallic material associated to said procedure. The invention falls within the technical sector of manufacturing processes through the contribution of material, applied to both pieces of revolution and different geometries, and for materials such as steels, special steels, nickel-based and titanium-based alloys and other metal alloys. BACKGROUND OF THE INVENTION
Son conocidos distintos procesos térmicos de fusión de material metálico sobre determinadas piezas, tales como el aporte por láser (también conocido por el término inglés 'Láser Cladding'), el cual es un proceso de alto interés industrial debido a que ofrece la posibilidad de aportar un material sobre una pieza base con una alta calidad de aporte y una elevada selectividad en la zona tratada. El aporte por láser se puede utilizar como una técnica de recubrimiento o como una técnica de fabricación y conformado rápida capa a capa. De manera particular, en cualquiera de las dos variantes, su uso en piezas de revolución es elevada ya que se puede colocar un dispositivo de aporte por láser y hacer girar la pieza mediante un centro de torneado o similar. Different thermal processes of fusion of metallic material on certain parts are known, such as the contribution by laser (also known by the English term 'Laser Cladding'), which is a process of high industrial interest because it offers the possibility of providing a material on a base piece with a high contribution quality and high selectivity in the treated area. The laser input can be used as a coating technique or as a manufacturing and fast forming technique layer by layer. In particular, in any of the two variants, its use in pieces of revolution is high since a contribution device can be placed by laser and rotate the piece by means of a turning center or the like.
Una de las principales dificultades que implica la técnica de aporte por láser es la de garantizar la integridad de los recubrimientos generados. De hecho, en ocasiones se requieren unas características específicas de estos recubrimientos que difícilmente se pueden lograr directamente mediante dicha técnica de aporte por láser. El principal problema proviene del propio proceso en sí, el cual se basa en la fusión de una fracción de material de la pieza base sobre el que se inyecta un material de aporte, y el cual puede fundirse también. El movimiento de la pieza, rotacional y/o longitudinal, hace que el láser deje de incidir en esa zona y se produce un enfriamiento rápido que solidifica el material previamente fundido, creando así una capa sólida de recubrimiento diluido con parte de material de la pieza base. Este proceso implica que existe una zona que ha vuelto a solidificarse después de la fusión y una zona afectada térmicamente. One of the main difficulties involved in the laser input technique is to guarantee the integrity of the coatings generated. In fact, sometimes specific characteristics of these coatings are required, which can hardly be achieved directly by said laser input technique. The main problem comes from the process itself, which is based on the fusion of a fraction of the base piece material on which a contribution material is injected, and which can also melt. The movement of the piece, rotational and / or longitudinal, causes the laser to stop affecting that area and It produces a rapid cooling that solidifies the previously molten material, thus creating a solid coating layer diluted with part of the base piece material. This process implies that there is an area that has solidified again after melting and a thermally affected area.
Además, es común la presencia de poros o huecos como resultado de la operación de aporte por láser, a pesar de trabajar con condiciones óptimas de proceso tales como trabajar en vacío y/o atmósferas inertes. Este hecho disminuye las propiedades mecánicas de las piezas y en ocasiones obliga a realizar un control exhaustivo de las piezas fabricadas mediante esta técnica, incrementando por tanto los costes de mantenimiento y prevención de fallos en servicio. In addition, the presence of pores or gaps is common as a result of the laser input operation, despite working with optimal process conditions such as working in a vacuum and / or inert atmospheres. This fact decreases the mechanical properties of the parts and sometimes requires an exhaustive control of the parts manufactured using this technique, thus increasing maintenance costs and preventing failures in service.
Por otro lado, existen procesos de mejora de las propiedades superficiales de las piezas fabricadas mediante deformación plástica. Uno de estos procesos es el conocido como bruñido mecánico (también conocido por su nombre inglés 'Burnishing'). El proceso de bruñido mecánico tiene generalmente dos variantes en función del tipo de herramienta que se utiliza: bruñido con rodillo o bruñido con bola. En ambos casos se utiliza una herramienta de elevada dureza. El bruñido con rodillo utiliza una herramienta con forma de rodillo y se aplica a piezas de revolución, mientras que en el bruñido con bola, la herramienta es una esfera capaz de desplazarse en cualquier dirección y se puede aplicara a cualquier geometría de pieza. A su vez, estos procesos se pueden llevar a cabo con diferentes métodos de generación de la presión necesaria: muelle mecánico, bomba hidráulica,... On the other hand, there are processes to improve the surface properties of parts manufactured by plastic deformation. One of these processes is known as mechanical burnishing (also known by its English name 'Burnishing'). The mechanical burnishing process generally has two variants depending on the type of tool used: roller burnishing or ball burnishing. In both cases a tool of high hardness is used. Roller burnishing uses a roller-shaped tool and is applied to revolution parts, while in ball burnishing, the tool is a sphere capable of moving in any direction and can be applied to any part geometry. In turn, these processes can be carried out with different methods of generating the necessary pressure: mechanical spring, hydraulic pump, ...
Independiente del tipo de bruñido que se trate, el proceso se basa en deformar plásticamente una capa de material. La mejora que se obtiene es doble: por un lado se mejora la rugosidad superficial, y por otro lado, se introducen tensiones residuales de compresión en la superficie y por debajo de ella, lo que incrementa la resistencia a fatiga de las piezas tratadas con esta técnica. Regardless of the type of burnish in question, the process is based on plastically deforming a layer of material. The improvement obtained is twofold: on the one hand the surface roughness is improved, and on the other hand, residual compression stresses are introduced on the surface and below it, which increases the fatigue resistance of the parts treated with this technique.
Algunos sistemas como el presentado en la solicitud WO-2009124034 buscan la aplicación de un recubrimiento mediante técnicas de bruñido, lo que consigue un aporte de material que queda adherido de modo mecánico a una pieza base. Some systems such as the one presented in the application WO-2009124034 seek the application of a coating by means of burnishing techniques, which achieves a contribution of material that is mechanically adhered to a piece base.
Por otro lado, existen diversas soluciones presentadas para ambos procesos de forma independiente. Así, hay soluciones para el bruñido de diferentes componentes como pistas de rodamientos, véase la solicitud WO-2009109303; de cigüeñales, véase la solicitud WO-2006135014; de engranajes, véase WO- 2008088748; de piezas de revolución, véase WO-2007045649; incluso el diseño de herramientas de bruñido para geometrías de piezas específicas, como por ejemplo las solicitudes WO-2008050012 y WO-2008037905. Todas estas solicitudes se basan en desarrollar herramientas específicas de bruñido para su aplicación final en piezas ya fabricadas. On the other hand, there are several solutions presented for both processes independently. Thus, there are solutions for the burnishing of different components such as bearing tracks, see application WO-2009109303; of crankshafts, see application WO-2006135014; for gears, see WO-2008088748; of revolution parts, see WO-2007045649; including the design of burnishing tools for specific part geometries, such as applications WO-2008050012 and WO-2008037905. All these requests are based on developing specific burnishing tools for final application in already manufactured parts.
Por otro lado, y de la misma manera, existen diferentes invenciones en los procesos de recubrimientos de piezas, tanto en el equipamiento que lleva a cabo el proceso como boquillas coaxiales, elementos de arrastre del polvo etc. Véanse solicitudes tales como WO-2005028151 , WO-2005084875, WO- 2007022567, y US-7259353. Como también en la aplicación del proceso de recubrimiento. Estos procesos se ejecutan en diferentes campos como por ejemplo para los implantes de cadera, véase US-7632575; como en recubrimientos biocompatibles, véase ES-2143938; como en reparación de moldes de botellas, véase WO-2009090622; y como en reparación de turbinas aeronáuticas, véase WO-2001 12381 . De nuevo, todas las invenciones se centran en el proceso de recubrimiento. On the other hand, and in the same way, there are different inventions in the processes of coating parts, both in the equipment that carries out the process such as coaxial nozzles, dust entrainment elements etc. See applications such as WO-2005028151, WO-2005084875, WO-2007022567, and US-7259353. As also in the application of the coating process. These processes are executed in different fields such as for hip implants, see US-7632575; as in biocompatible coatings, see ES-2143938; as in repair of bottle molds, see WO-2009090622; and as in repair of aeronautical turbines, see WO-2001 12381. Again, all inventions focus on the coating process.
Existen algunas invenciones más cercanas del estado de la técnica que combinan los procesos de recubrimiento por aporte de material y posterior proceso de acabado de la superficie, fundamentalmente pulido abrasivo como por ejemplo la solicitud JP-4083862, y el rectificado o mecanizado. En algún caso se plantea el uso combinado de herramientas de aporte de material y acabado como por ejemplo la solicitud estadounidense US-2005107003; pero tratándose de nuevo de procesos de arranque de material mediante procesos abrasivos: pulido o rectificado. There are some inventions closer to the state of the art that combine the processes of coating by contribution of material and subsequent process of surface finishing, mainly abrasive polishing such as for example the application JP-4083862, and grinding or machining. In some cases, the combined use of material and finishing tools is proposed, such as US application 2005-2007003; but in the case of material removal processes through abrasive processes: polishing or grinding.
DESCRIPCIÓN DE LA INVENCIÓN La presente invención se refiere a un procedimiento para la aportación de material metálico sobre una determinada pieza y la posterior etapa de bruñido, donde dicho procedimiento para la aportación de material metálico sobre una pieza comprende las siguientes etapas: DESCRIPTION OF THE INVENTION The present invention relates to a process for the contribution of metallic material on a particular piece and the subsequent stage of burnishing, wherein said procedure for the contribution of metallic material on a piece comprises the following steps:
a) aportación de material metálico, mediante un proceso térmico de fusión del material metálico, al menos parcialmente en la superficie de dicha pieza, formando una capa de material metálico y una zona afectada térmicamente, y  a) contribution of metallic material, by means of a thermal fusion process of the metallic material, at least partially on the surface of said piece, forming a layer of metallic material and a thermally affected area, and
b) bruñir dicha capa,  b) burnish said layer,
donde las etapas a) y b) se realizan mediante al menos un cabezal combinado que comprende al menos un dispositivo de aportación de dicho material metálico y al menos una herramienta de bruñido, y realizándose las etapas con un retraso suficiente para que la zona afectada térmicamente se encuentre todavía a una temperatura donde la tensión de fluencia a compresión sea menor que la presión de bruñido  where steps a) and b) are carried out by means of at least one combined head comprising at least one device for supplying said metal material and at least one burnishing tool, and the stages being carried out with a sufficient delay so that the thermally affected area is is still at a temperature where the compression creep stress is lower than the burnish pressure
El resultado es la mejora de la integridad estructural de las piezas obtenidas, independientemente del material metálico con el que se trabaje, siempre y cuando éste tenga una capacidad de deformación plástica susceptible de ser bruñido mecánicamente; ya que el dispositivo de aportación de material metálico genera una capa de material aportado y donde, a continuación, la herramienta de bruñido deforma el material en caliente plásticamente generando una capa de menor rugosidad superficial y de mayor integridad estructural. The result is the improvement of the structural integrity of the pieces obtained, regardless of the metal material with which one works, as long as it has a plastic deformability capable of being mechanically burnished; since the metallic material contribution device generates a layer of contributed material and where, then, the burnishing tool deforms the hot material plastically generating a layer of less surface roughness and greater structural integrity.
Al deformar plásticamente la pieza obtenida se consigue mejorar sustancialmente la rugosidad superficial y se reducen las tensiones residuales de compresión en la propia superficie como debajo de ella; incrementando por tanto la resistencia a fatiga de las piezas obtenidas por este procedimiento. By plastically deforming the piece obtained, the surface roughness is substantially improved and the residual compression stresses on the surface itself as below it are reduced; therefore increasing the fatigue resistance of the parts obtained by this procedure.
Adicionalmente se observa cómo el dispositivo de aportación se realiza de manera combinada aprovechando el calor residual en la pieza para que el bruñido se realice de tal forma que se precise de una menor presión y donde el requerimiento energético sea menor frente al estado de la técnica actual. El nivel de porosidad tras ambas etapas es mínimo gracias a la segunda etapa de bruñido y el tiempo de ejecución de todo el proceso es muy reducido debido a la aplicación de un cabezal combinado con ambos procedimientos; a tener en cuenta que el proceso puede estar completamente automatizado para la realización de piezas conformadas de esta forma y en grandes series. Además la homogeneidad del recubrimiento de material metálico es muy superior a las operaciones del aporta de material metálico de manera aislada. Additionally, it is observed how the contribution device is made in a combined way taking advantage of the residual heat in the piece so that the burnishing is carried out in such a way that a lower pressure is required and where the energy requirement is lower compared to the current state of the art . The level of porosity after both stages is minimal thanks to the second stage of burnishing and the execution time of the whole process is very reduced due to the application of a head combined with both procedures; to take into account that the process can be completely automated for the realization of pieces formed in this way and in large series. In addition, the homogeneity of the coating of metallic material is far superior to the operations of the metallic material contribution in isolation.
Preferentemente la capa superficial a deformar plásticamente y obtenida mediante la aportación de material metálico, oscila entre las 5 y las 350 mieras de espesor. Preferably the surface layer to be deformed plastically and obtained by the contribution of metallic material, ranges between 5 and 350 microns thick.
Se contempla la posibilidad de que la pieza a conformar sea una pieza de revolución, de modo que pueda ser anclada en sus extremos, y mediante un eje de giro se proceda a realizar ambas etapas mediante el cabezal combinado pudiendo ser los movimientos: The possibility that the piece to be formed is a piece of revolution is contemplated, so that it can be anchored at its ends, and by means of an axis of rotation, both stages can be carried out by means of the combined head and the movements can be:
de avance por parte del propio cabezal combinado; es decir, longitudinalmente y cubriendo parcialmente o la totalidad de la pieza de revolución a conformar; o - de avance por parte del eje de revolución; siendo esta opción minoritaria para la mayoría de los casos.  forward by the combined head itself; that is, longitudinally and partially or partially covering the entire piece of revolution to be shaped; or - of advance by the axis of revolution; this minority option being for most cases.
El sistema para la aportación de materiales metálicos comprende al menos un sistema de arrastre que regula la distancia entre dicha, al menos una, herramienta de bruñido respecto de dicho, al menos un, dispositivo de aportación de material metálico. The system for the contribution of metallic materials comprises at least one drive system that regulates the distance between said at least one burnishing tool with respect to said at least one device for providing metallic material.
De esta manera y mediante un sistema sencillo se podrá regular el retraso de la aplicación de dicha, al menos una, herramienta de bruñido según el material a conformar o el material metálico a aportar; permitiendo disminuir la distancia para materiales con alto grado de conductividad térmica y viceversa. In this way and by means of a simple system, the delay in the application of said at least one burnishing tool can be regulated according to the material to be formed or the metallic material to be provided; allowing to reduce the distance for materials with a high degree of thermal conductivity and vice versa.
Adicionalmente el sistema de aportación podrá ser guiado mediante una máquina tipo centro de torneado para el caso de piezas a conformar de revolución; un robot o cualquier plataforma cinemática capaz de guiar dicho, al menos un, sistema de aportación de material metálico. Additionally, the contribution system may be guided by a turning center type machine in the case of revolution parts; a robot or any kinematic platform capable of guiding said, at least one, metallic material contribution system.
Preferentemente el sistema de arrastre comprende una regla graduada con una corredera dispuesta sobre ella, de manera que la regulación se estime mediante unidades de longitud dotando al conjunto de una elevada precisión y pudiendo realizar unos parámetros que relacionan la distancia frente a tiempo de espera de la aplicación de dicha, al menos una, herramienta de bruñido. Preferably, the drag system comprises a graduated ruler with a slide arranged on it, so that the regulation is estimated by means of length units providing the assembly with high precision and being able to perform parameters that relate the distance to the waiting time of the application of said, at least one, burnishing tool.
El sistema de arrastre puede estar controlado de manera completamente automatizada, por ejemplo para grandes series de piezas; o servocontrolada mediante la incorporación de un eje adicional al sistema objeto de invención donde se ejecute dichas operaciones. The drag system can be controlled in a fully automated manner, for example for large series of parts; or servo-controlled by incorporating an additional axis to the system object of the invention where said operations are carried out.
Se contemplan distintas opciones referentes a la posibilidad de utilizar un tipo de dispositivo de aportación u otro, pudiendo ser: Different options are contemplated regarding the possibility of using one type of contribution device or another, which may be:
