Description
Cañón de ánima pre-tensada y procedimiento de fabricación del mismo.Pre-tensioned bore barrel and manufacturing process thereof.
El objeto de la presente invención es un cañón de ánima estriada pre-tensada que evite los problemas derivados del progresivo calentamiento del cañón en una sucesión larga de disparos.The object of the present invention is a cannon of striated pre-tensioned bore that avoids problems derived from the progressive heating of the canyon in a Long succession of shots.
El problema de todo cañón es el progresivo calentamiento de éste, durante la sucesión de disparos. Este aumento de temperatura hace que las dilataciones aparezcan y se liberen las tensiones acumuladas en el material del cañón durante el proceso de fabricación. Todo esto hace que la pérdida de precisión aparezca inexorablemente al alcanzarse la temperatura crítica.The problem with every canyon is the progressive heating of this one, during the succession of shots. This temperature rise causes dilations to appear and release the tensions accumulated in the barrel material during the fabrication process. All this causes the loss of precision appears inexorably when the critical temperature is reached.
En los cañones de ánima estriada, durante los disparos, el cañón entra en un movimiento armónico simple, similar al que una cuerda experimenta al ser sacudido uno de sus extremos estando el otro libre. Según la intensidad de éste, la boca del cañón describirá un óvalo de mayor o menor amplitud. Cuanto mayor sea éste, la precisión se ve más comprometida.In the fluted bore canyons, during shots, the cannon enters a simple, similar harmonic movement to which a rope experiences when one of its ends is shaken The other being free. According to its intensity, the mouth of the Cannon will describe an oval of greater or lesser amplitude. The older Be this, the precision is more compromised.
Este efecto se intenta paliar dando a las paredes de los cañones un mayor grosor, con el fin de conseguir mayor rigidez, lo que equivaldría, simplemente, a hacer más gruesa la cuerda. Esto no hace más que retrasar el tan temido efecto de la pérdida de precisión, ya que las dilataciones terminan por aparecer siendo después más permanentes, por la mayor cantidad de calor almacenada. Hay que tener en cuenta a su vez, el aumento masivo del peso del arma, haciendo muy engorroso y molesto su manejo.This effect is attempted to alleviate by giving canyon walls thicker, in order to get greater rigidity, which would simply mean thicker rope. This only delays the much feared effect of the loss of precision, since the dilations end up appearing being more permanent afterwards, due to the greater amount of heat stored In turn, the massive increase in weight of the weapon, making its handling very cumbersome and annoying.
Para paliar los problemas arriba mencionados, se presenta el cañón de ánima pre-tensada, objeto de la presente patente de invención, el cual comprende, al menos:To alleviate the problems mentioned above, it presents the pre-tensioned bore barrel, object of The present invention patent, which comprises at least:
(a) un ánima estriada, propiamente el cañón de ánima estriada;(a) a fluted bore, properly the cannon of fluted bore;
(b) una camisa exterior con un alto momento de inercia polar configurada para soportar la tensión del ánima estriada y al mismo tiempo dar rigidez al conjunto;(b) an outer shirt with a high moment of Polar inertia configured to withstand the tension of the bore striated and at the same time give rigidity to the whole;
(c) una tuerca de sustentación que permite el trabajo solidario del ánima estriada y la camisa exterior.(c) a lift nut that allows solidarity work of the striated bore and outer jacket.

En el procedimiento de fabricación propone elevar la temperatura del cañón (ánima) ligeramente por encima de la temperatura de trabajo, preferentemente a una temperatura del orden de entre 250ºC y 300ºC, con el fin de dilatarlo ligeramente más de lo necesario. Esto se produce a temperaturas en las que el material se encuentra dentro del periodo elástico.In the manufacturing procedure proposed raise the temperature of the barrel (anima) slightly above the working temperature, preferably at a temperature of order between 250ºC and 300ºC, in order to expand it slightly more than necessary. This occurs at temperatures at which the material is within the elastic period.
Posteriormente, se monta la camisa exterior y se sujeta ésta al cañón firmemente con la tuerca.Subsequently, the outer jacket is mounted and Hold the barrel firmly with the nut.
Al retornar el cañón previamente calentado a su temperatura inicial, recupera el alargamiento experimentado durante dicha operación. Al no conseguirlo, ya que la camisa exterior se lo impide, el ánima se queda en una posición similar a la de una cuerda tensada desde sus extremos. En esta situación, la intensidad del efecto armónico simple queda claramente eliminada ya que, al estar toda el ánima tensionada, es prácticamente imposible que este fenómeno se produzca. De esta forma el óvalo definido por la boca del cañón, se ve, si no eliminado en su totalidad, si reducido a unas proporciones despreciables.Upon returning the previously heated barrel to its initial temperature, recovers the elongation experienced during said operation. Not getting it, since the outer shirt will prevents, the soul stays in a position similar to that of a tensioned rope from its ends. In this situation, the intensity of the simple harmonic effect is clearly eliminated since, at being all stressed up, it's practically impossible for this phenomenon occurs. In this way the oval defined by the mouth of the canyon, it is seen, if not eliminated in its entirety, if reduced to negligible proportions.
A continuación se pasa a describir de manera muy breve una serie de dibujos que ayudan a comprender mejor la invención y que se relacionan expresamente con una realización de dicha invención que se presenta como un ejemplo no limitativo de ésta.Then it goes on to describe very brief a series of drawings that help to better understand the invention and that expressly relate to an embodiment of said invention presented as a non-limiting example of is.

Figura 2.- Sección longitudinal esquematizada del cañón de ánima pre-tensada, objeto de la presente patente de invención con la camisa exterior de perfil inclinado.Figure 2.- Schematic longitudinal section of the pre-tensioned bore barrel, object of the present invention patent with outer profile jacket inclined.
Tal y como se puede observar en las figuras adjuntas, el cañón de ánima pre-tensada objeto de la presente invención comprende, al menos, un cañón de ánima estriada (1) sobre la que se sitúa una camisa exterior (2) con un alto momento de inercia polar configurada para soportar la tensión del cañón (1); y una tuerca de unión (3) entre la camisa exterior (2) y el cañón de ánima estriada (1); donde, además, la camisa exterior (2) se monta sobre el cañón (1) fijándose solidariamente el conjunto por medio de la tuerca de unión (3).As can be seen in the figures attached, the pre-tensioned bore cannon object of the present invention comprises at least one bore cannon striated (1) on which an outer jacket (2) with a high polar moment of inertia configured to withstand voltage of the canyon (1); and a union nut (3) between the outer jacket (2) and the fluted bore barrel (1); where, in addition, the shirt exterior (2) is mounted on the barrel (1) fixing the assembly by means of the union nut (3).
El procedimiento de fabricación del cañón en una primera realización práctica comprende, al menos, las siguientes etapas:The cannon manufacturing process in a first practical embodiment comprises at least the following stages:
(i) una primera etapa de elevación de la temperatura del cañón (1) ligeramente por encima de la temperatura de trabajo, preferentemente entre 250ºC y 300ºC, dilatándolo dentro de los márgenes de elasticidad de dicho cañón (1); y(i) a first stage of elevation of the barrel temperature (1) slightly above the temperature working, preferably between 250ºC and 300ºC, dilating it inside of the elasticity margins of said barrel (1); Y
(ii) una segunda etapa de montaje de la camisa exterior (2) sobre el cañón (1) cubriéndolo en su totalidad y fijándose solidariamente ambos cuerpos por medio de la tuerca de unión (3).(ii) a second stage of mounting the shirt outside (2) over the barrel (1) covering it completely and fixing both bodies jointly by means of the nut of union (3).
\vskip1.000000\baselineskip\ vskip1.000000 \ baselineskip
En una segunda realización práctica, se realiza el montaje con todas las piezas a temperatura ambiente, donde se monta la camisa exterior (2) sobre el cañón (1) y se sujetaran ambas con la tuerca (3). Para este montaje, es necesario dejar el cañón (1) más largo de su longitud final, con el fin de que sobresalga por delante de la tuerca la longitud necesaria para poder hacer un amarre firme en ambos extremos del cañón (1).In a second practical embodiment, it is performed assembly with all parts at room temperature, where mount the outer jacket (2) on the barrel (1) and they will be held both with the nut (3). For this assembly, it is necessary to leave the cannon (1) longer than its final length, so that the length necessary for the nut to protrude be able to make a firm mooring at both ends of the barrel (1).
Ya con el montaje hecho, éste se sujetara por los extremos del cañón (1) en una máquina de tracción, con el fin de producirle un alargamiento a éste, equivalente a la dilatación producida por la temperatura del anterior sistema de montaje en caliente. Una vez conseguida esta elongación, se procederá a apretar la tuerca (3) contra la camisa (2).With the assembly done, it will be held by the ends of the barrel (1) in a traction machine, in order of elongating it, equivalent to dilation produced by the temperature of the previous mounting system in hot. Once this elongation is achieved, we will proceed to tighten the nut (3) against the shirt (2).
De ésta forma, al sacar el conjunto de la máquina de tracción, el cañón (1) quedara permanentemente pre-tensado, ya que la camisa (2), le impedirá recuperar su posición inicial.In this way, when taking out the whole of the traction machine, the barrel (1) will remain permanently pre-tensioned, since the shirt (2) will prevent Recover your starting position.
Así mismo, opcionalmente se podrá rellenar la cámara de aire que queda entre el cañón (1) y la camisa (2) con algún material de baja densidad y un alto poder de conducción térmica, con el fin de facilitar el mejor equilibrio térmico entre estas dos piezas.Also, optionally you can fill in the air chamber that is between the barrel (1) and the jacket (2) with some low density material and high driving power thermal, in order to facilitate the best thermal balance between These two pieces.
