Description

Cañón de ánima pre-tensada y procedimiento de fabricación del mismo.Pre-tensioned bore barrel and manufacturing process thereof.

Objeto de la invenciónObject of the invention

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.

Antecedentes de la invenciónBackground of the invention

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.

Descripción de la invenciónDescription of the invention

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. 

       \vskip1.000000\baselineskip\ vskip1.000000 \ baselineskip

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.
