Procedimiento de limpieza de restos de galvanizado en roscas y máquina para dicho procedimiento.Procedure for cleaning debris from galvanized threads and machine for said procedure.
La presente invención está relacionada con el tratamiento de galvanizado de tubos o barras provistos de partes roscadas, proponiendo un procedimiento y una máquina para limpiar las partes roscadas, con el fin de eliminar de las roscas una parte del galvanizado para que resulten adecuadamente operativas, pero manteniendo las propiedades de protección del recubrimiento.The present invention is related to the galvanized treatment of tubes or bars provided with parts threaded, proposing a procedure and a machine to clean the threaded parts, in order to remove a part from the threads galvanized so that they are properly operational, but maintaining the protective properties of the coating.
Es habitual la práctica de aplicar a los tubos y barras de hierro o acero un recubrimiento de galvanizado, para dotarlos de una capa protectora, fundamentalmente contra la oxidación, de manera que, cuando dichos elementos poseen partes roscadas, debido a que la galvanización es un proceso de aporte de material, en las superficies no uniformes, como las zonas roscadas, el espesor resultante del recubrimiento no es uniforme, lo cual supone una merma de la funcionalidad para los montajes roscados.It is common practice to apply to the tubes and iron or steel bars a galvanized coating, for provide them with a protective layer, mainly against oxidation, so that when these elements have parts threaded, because galvanization is a process of contribution of material, on non-uniform surfaces, such as threaded areas, the resulting thickness of the coating is not uniform, which It supposes a decrease of the functionality for the assemblies threaded
En el caso, por ejemplo, de los puntales de sujeción de los encofrados de obras, una solución adoptada para evitar ese problema de la funcionalidad de las roscas por el galvanizado, es realizar las partes extremas roscadas de manera independiente del cuerpo del elemento, galvanizándose el cuerpo y uniéndose luego a él por soldadura las partes extremas roscadas sin galvanizar.In the case, for example, of the struts of clamping of the formwork of works, a solution adopted for avoid that problem of thread functionality by the galvanized, is to make the threaded end parts so independent of the body of the element, galvanizing the body and joining it by welding the threaded end parts without galvanize.
Esta solución tiene el inconveniente de las uniones soldadas que hay que realizar para incorporar al cuerpo del elemento las partes extremas roscadas, lo cual incrementa los costos de manera considerable, y en algunos casos no se admite esa formación de los elementos mediante partes independientes unidas.This solution has the disadvantage of welded joints that must be made to incorporate the body of the element the threaded end parts, which increases the costs considerably, and in some cases that is not supported formation of the elements by independent parties united.
Además, con dicha solución las partes extremas roscadas quedan sin protección, resultando propensas a la oxidación, lo que supone una rápida evolución de deterioro, y la oxidación que se produce causa también una deficiencia en la funcionalidad de los montajes roscados.In addition, with said solution the extreme parts threads are left unprotected, being prone to oxidation, which implies a rapid evolution of deterioration, and the oxidation that occurs also causes a deficiency in the functionality of threaded assemblies.
De acuerdo con la invención se proponen un procedimiento y una máquina para limpiar las roscas de los elementos tubulares o barras galvanizados, permitiendo eliminar de manera ventajosa una parte del galvanizado de las partes roscadas, para mantener íntegra la funcionalidad de las mismas, manteniendo las propiedades de protección del recubrimiento.In accordance with the invention, a procedure and a machine to clean the threads of the tubular elements or galvanized bars, allowing removal of advantageously a galvanized part of the threaded parts, to maintain their functionality in full, maintaining The protective properties of the coating.
El procedimiento preconizado consiste en aplicar sobre las partes roscadas de los elementos galvanizados, un calentamiento capaz de poner la capa exterior del recubrimiento galvanizado en estado semifundido y la capa interior de contacto con el elemento base a una temperatura que no llega a determinar la fusión pero que sin embargo favorece la adhesión al elemento base, proyectándose inmediatamente después de dicho calentamiento un chorro de aire a presión, mediante el cual se elimina la capa exterior de material semifluido del recubrimiento, al mismo tiempo que se enfría la capa sólida interior, que permanece unida al elemento base.The recommended procedure is to apply on the threaded parts of the galvanized elements, a heating capable of putting the outer layer of the coating galvanized in semi-molten state and the inner contact layer with the base element at a temperature that cannot be determined the fusion but that nevertheless favors the adhesion to the element base, projecting immediately after said heating a jet of pressurized air, by which the layer is removed outer semi-fluid coating material at the same time that the inner solid layer cools, which remains attached to the base element.
Para llevar al estado de semifusión a la capa exterior del recubrimiento galvanizado se realiza un calentamiento hasta 300-330ºC, con el cual la capa interior de contacto con el elemento base se mantiene a 160-170ºC, aplicándose la proyección de aire para eliminar el material semifundido, a una presión de 8-10 Kg/cm^{2}, con lo que se consigue mantener un espesor de recubrimiento constante y uniforme de 50-60 micras.To bring the semi-fusion state to the layer outside of the galvanized coating a heating is performed up to 300-330 ° C, with which the inner layer of contact with the base element is maintained at 160-170 ° C, applying the air projection to remove semi-molten material, at a pressure of 8-10 Kg / cm2, with which it is possible to maintain a constant and uniform coating thickness of 50-60 microns
El desarrollo del procedimiento se prevé con una máquina formada por un cabezal en el que van incorporadas dos boquillas, una de ellas constitutiva de un soplete conectado a un suministro de gases combustibles y la otra conectada a un suministro de aire a presión, yendo dicho cabezal en disposición de aproximación y de desplazamiento longitudinal de las boquillas respecto de una zona de posicionamiento de la parte extrema roscada de los tubos o barras de aplicación.The development of the procedure is foreseen with a machine formed by a head in which two are incorporated nozzles, one of them constituting a torch connected to a supply of combustible gases and the other connected to a supply of pressurized air, said head being disposed of approach and longitudinal displacement of the nozzles with respect to a positioning area of the threaded end part of the tubes or bars of application.
La máquina incorpora además unos soportes formados por pares de ruedas dotadas de accionamiento motriz giratorio, para el apoyo de los elementos de aplicación del proceso de limpieza de las roscas, en combinación con los cuales apoyos se dispone un tope superior dispuesto en montaje móvil de elevación y descenso, formado por un par de ruedas giratoriamente libre, mediante el cual se sujeta el elemento de aplicación contra los soportes de apoyo que le mueven en rotación.The machine also incorporates some supports formed by pairs of wheels equipped with motor drive rotating, for the support of the process application elements thread cleaning, in combination with which braces are it has an upper stop arranged in mobile lifting assembly and descent, formed by a pair of wheels rotatably free, by which the application element is held against the support brackets that move you in rotation.
De este modo, mediante la combinación del giro del elemento de aplicación del proceso, con el movimiento de las boquillas del cabezal y la actuación mediante la boquilla soplete primero y mediante la boquilla de proyección de aire a presión después, se obtiene la aplicación del proceso de limpieza uniformemente sobre toda la zona roscada de los elemento de aplicación, eliminando la capa exterior del galvanizado y dejando una capa interior del mismo sobre el elemento base.Thus, by combining the turn of the process application element, with the movement of the nozzle of the head and the action by means of the torch nozzle first and by means of the pressure air projection nozzle afterwards, the application of the cleaning process is obtained evenly over the entire threaded area of the elements of application, removing the outer layer of the galvanized and leaving an inner layer thereof on the base element.
En la máquina se hallan previstos además unos soportes accesorios, para el apoyo en giro libre de la parte posterior de los elementos de aplicación que sobresale de la zona de apoyo sobre los soporte de accionamiento giratorio, con el fin de evitar los esfuerzos de flexión.In the machine there are also some accessory brackets, for free-spin support of the part rear of the application elements protruding from the area of support on the rotating drive brackets, in order to avoid bending efforts.
Por todo ello, el procedimiento y la máquina del objeto de la invención resultan de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función de acondicionamiento de las roscas de elementos galvanizados, manteniendo la funcionalidad de dichas roscas con un recubrimiento de protección de las mismas.For all this, the procedure and the machine of the object of the invention result from characteristics certainly advantageous, acquiring own life and character preferred for the conditioning function of the threads of galvanized elements, maintaining the functionality of said threads with a protective coating thereof.

El objeto de la invención se refiere a un procedimiento para limpiar las roscas de elementos galvanizados, tales como tubos o barras, con el fin de dejar a dichas roscas en adecuadas condiciones de funcionalidad para los montajes roscados, pero manteniendo en ellas una capa protectora de galvanizado.The object of the invention relates to a procedure to clean the threads of galvanized elements, such as tubes or bars, in order to leave said threads in adequate functionality conditions for threaded assemblies, but maintaining in them a protective coating of galvanized.
El procedimiento preconizado consiste en aplicar sobre las zonas roscadas (1) de los elementos galvanizados (2) de aplicación, una proyección de calentamiento tal que la capa exterior del galvanizado adquiera una temperatura a la que el material quede en estado semifundido, mientras que la capa interior que se halla en contacto con el elemento base quede a una temperatura en la que el material se mantenga consistentemente sólido.The recommended procedure is to apply on the threaded areas (1) of the galvanized elements (2) of application, a heating projection such that the layer galvanized exterior acquires a temperature at which the material remains in semi-molten state, while the inner layer which is in contact with the base element is one temperature at which the material is consistently maintained solid.
Inmediatamente después de dicho calentamiento, se aplica una proyección de aire a presión, mediante la cual se arrastra el material semifundido de la capa exterior del galvanizado, al mismo tiempo se que enfría la capa sólida interior que se halla en contacto con el elemento base.Immediately after said heating, a pressurized air projection is applied, whereby drag the semi-molten material from the outer layer of the galvanized, at the same time I know that the inner solid layer cools which is in contact with the base element.
El calentamiento del galvanizado existente sobre las zonas roscadas (1) que se someten al procedimiento de limpieza, se realiza de forma que la capa externa del material queda a una temperatura de 300-330ºC, a la cual el material del galvanizado resulta en estado semifundido, en tanto que la capa interior que se halla en contacto con el elemento base queda a una temperatura de 160-170ºC, a la cual el material no llega a reblandecer, favoreciendo sin embargo la adherencia al elemento base.The existing galvanized heating on the threaded areas (1) that undergo the cleaning procedure, it is done so that the outer layer of the material is at a temperature of 300-330 ° C, at which the material of the galvanized results in semi-molten state, while the layer interior that is in contact with the base element is at a temperature of 160-170 ° C, at which the material does not it becomes softer, however favoring adherence to base element.
De este modo, mediante la proyección del aire a
presión, después del calentamiento, se elimina la capa exterior del
galvanizado, por arrastre del material semifundido mediante dicho
aire a presión, con lo cual la rosca queda sin acumulación de
material sobre ella que dificulte la funcionalidad de los montajes
roscados, en tanto que sobre el elemento base se mantiene una capa
de 50-60 micras, que garantiza la protección
anticorrosiva de la zona roscada (1) de aplica-
ción.Thus, by spraying the pressurized air, after heating, the outer layer of the galvanized material is removed, by dragging the semi-molten material by means of said pressurized air, whereby the thread remains without accumulation of material on it that makes it difficult to functionality of threaded assemblies, while a 50-60 micron layer is maintained on the base element, which guarantees anticorrosive protection of the threaded area (1) of application.
tion.
Para ello, la aplicación de la proyección del aire a presión sobre la zona roscada (1) a limpiar, se realiza desde una distancia aproximada de 20 milímetros y a una presión de 8-10 Kg/cm^{2}. La aplicación de esta proyección de aire a presión se realiza además inmediatamente después del calentamiento (con un desfase de 2-3 segundos como máximo), para que la temperatura del material del galvanizado no sufra una variación significativa respecto del calentamiento.To do this, the application of the projection of the pressurized air over the threaded area (1) to be cleaned, is performed from a distance of approximately 20 millimeters and at a pressure of 8-10 Kg / cm2. The application of this projection Pressurized air is also performed immediately after warm-up (with a 2-3 second lag as maximum), so that the temperature of the galvanized material does not suffer a significant variation with respect to heating.
Para ejecutar dicho procedimiento de limpieza de las zonas roscadas (1) de elementos tubulares o barras (2) de aplicación, se prevé una máquina provista con un cabezal (3) en el que van incorporadas sendas boquillas (4 y 5), una de ellas (4) a modo de un soplete, en conexión con un suministro de combustibles, para la aplicación del calentamiento sobre las zonas roscadas (1) galvanizadas, y la otra (5) en conexión con un suministro de aire a presión, para la aplicación de la proyección de aire destinada a arrastrar la capa semifundida exterior del galvanizado después del calentamiento.To execute said cleaning procedure of the threaded areas (1) of tubular elements or bars (2) of application, a machine provided with a head (3) is provided in the that are incorporated two nozzles (4 and 5), one of them (4) to torch mode, in connection with a fuel supply, for the application of heating on threaded areas (1) galvanized, and the other (5) in connection with an air supply to pressure, for the application of air projection intended for drag the outer semi-molded layer of the galvanized after the heating.
