Abstract
Perfeccionamientos introducidos en pistolas. Se pretende conseguir evitar las accidentales roturas y gripajes del arma por mal funcionamiento de algunos de sus componentes, que con frecuencia suceden. Para ello, se ha comprobado que es necesario modificar el diseño y estructura de las piezas del arma conocidas como rampón (1) o pieza de engarce del cañón y desconector (2), vinculadas ambas al cañón (4) del arma, y siendo el desconector (2) el elemento que fija o libera al rampón (1). El rampón (1) modifica su geometría al dotarle de radios del orden de 0,5 mm en las aristas de las zonas de fatiga, construyéndose por mecanizado total partiendo de material en bruto. El desconector (2) también se construye por mecanizado partiendo de material en bruto en acero de muelle, sometiéndose después ambos elementos a un tratamiento de temple, revenido y sulfinuzación.Refinements introduced in guns. It is intended to avoid accidental breakages and seizures of the weapon by malfunctioning of some of its components, which often occur. To do this, it has been verified that it is necessary to modify the design and structure of the weapon parts known as the rampon (1) or crimp part of the barrel and disconnector (2), both linked to the barrel (4) of the weapon, and being the disconnector (2) the element that fixes or releases the rampon (1). The rampon (1) modifies its geometry by providing radii of the order of 0.5 mm in the edges of the fatigue zones, being constructed by total machining starting from raw material. The disconnector (2) is also constructed by machining starting from raw material in spring steel, then both elements are subjected to a tempering, tempering and sulfining treatment.
Description

La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a unos perfeccionamientos introducidos en pistolas, con los que se consiguen notables ventajas en el funcionamiento general de este arma de fuego, aumentando la vida útil de la misma al evitarse accidentales roturas y gripajes en algunas de sus piezas integrantes, lo que sucede habitualmente.The present invention, as expressed by the set forth in this specification, refers to some perfections introduced in guns, with which they get remarkable advantages in the overall operation of this firearm, increasing its useful life by avoiding accidental breaks and seizures in some of its parts members, what usually happens.
Los perfeccionamientos se centran concretamente en las piezas del arma denominadas comúnmente rampón (pieza de engarce) y desconector, elementos estos vinculados al cañón, como veremos más adelante en relación con las figuras.The refinements focus specifically in the parts of the weapon commonly called rampon (piece of crimp) and disconnector, these elements linked to the barrel, such as We will see later in relation to the figures.
Originalmente, las piezas anteriormente indicadas: rampón y desconector, se fabrican mediante procesos de fundición, lo cual producía una gran dispersión de calidad del material y de sus condiciones de resistencia, originando la rotura anticipadamente e inutilizando el uso de la pistola.Originally, the pieces previously indicated: rampon and disconnector, are manufactured by means of foundry, which produced a large dispersion of the quality of material and its resistance conditions, causing breakage in advance and making use of the gun useless.
En líneas generales, con los perfeccionamientos introducidos en pistolas, objeto de la presente invención, se consigue resolver satisfactoriamente los problemas comentados y evitar eficazmente la posibilidad de roturas y gripajes del arma, lo que tiene lugar actualmente por la mala calidad del material, estructura y configuración geométrica imprecisa con que se construyen exclusivamente los elementos a los que hemos hecho referencia, es decir, el rampón y el desconector. El rampón es el elemento que porta una rampa asociada al desconector, siendo una pieza de engarce para anclaje del cañón.In general, with the improvements introduced into guns, object of the present invention, is manages to satisfactorily solve the commented problems and effectively avoid the possibility of breakages and seizures of the weapon, what is currently taking place due to the poor quality of the material, imprecise geometric structure and configuration with which exclusively build the elements we have made reference, that is, the rampon and the disconnector. The rampon is the element that carries a ramp associated to the disconnector, being a crimp piece for anchoring the barrel.
Acorde con la invención el rampón ofrece un nuevo diseño que contempla en los puntos críticos o zonas de fatiga de su estructura, unas superficies de transición entre diferentes planos de su geometría que, contrariamente a su actual diseño en el que se definen aristas vivas, se les dota de radios del orden de 0,5 milímetros. Esto, unido a otras características que veremos más adelante, permite un funcionamiento correcto en su actuación repetitiva debido a su cometido.According to the invention, the rampon offers a new design that contemplates at critical points or areas of fatigue of its structure, transition surfaces between different planes of its geometry which, contrary to its current design in the that live edges are defined, they are provided with radii of the order of 0.5 mm This, together with other features that we will see more forward, it allows a correct operation in its performance repetitive due to its purpose.
Estas piezas mencionadas están fabricadas partiendo de material en bruto, de una calidad concertada mediante certificados originales, y posteriormente se mecanizan por completo hasta conseguir la forma final deseada.These mentioned parts are manufactured starting from raw material, of a concerted quality through original certificates, and subsequently fully machined until you get the desired final shape.
A continuación se les somete a un tratamiento térmico de temple, revenido y sulfinuzación, lo que conlleva una resistencia superficial elevada, como también lo es y debido al tratamiento final, la capacidad al desgaste y al gripaje.They are then subjected to a treatment tempering of tempering, tempering and sulfinuzación, which entails a high surface resistance, as it is also due to final treatment, the ability to wear and seizure.

Haciendo referencia a la numeración adoptada en las figuras, podemos ver cómo los perfeccionamientos introducidos en pistolas, que la invención propone, están localizados en el rampón (1) o pieza de engarce y en el desconector (2) del arma, en este caso la pistola (3) y vinculados al cañón (4) de la misma.Referring to the numbering adopted in the figures, we can see how the improvements introduced in guns, which the invention proposes, are located in the Rampon (1) or crimping piece and in the disconnect (2) of the weapon, in this case the gun (3) and linked to the barrel (4) of it.
El rampón (1) define por su funcionamiento una pieza de engarce y presenta la geometría de aristas romas con radios de 0,5 milímetros que se observan claramente en la representación geométrica detallada de esta pieza, contemplada en las figuras 3 a 7. Estos radios están referenciados con R. Existen otros radios ligeramente mayores (R'=l y R''=1'5 mm).Rampon (1) defines by its operation a crimping piece and presents the geometry of blunt edges with 0.5 mm radii that are clearly seen in the detailed geometric representation of this piece, contemplated in Figures 3 to 7. These radios are referenced with R. There are other slightly larger radii (R '= l and R' '= 1.5 mm).
El rampón (1) está situado entre los dos tacones del cañón (4) y puede oscilar sobre el más delantero para enclavarse o no en el trasero, por medio del elemento desconector (2).The rampon (1) is located between the two heels of the cannon (4) and can swing over the frontmost to interlock or not in the rear, by means of the disconnecting element (2).
Por su parte, el desconector (2) se guía en el orificio (5) del tacón posterior del cañón (4) (ver figura 2), y está construido preferentemente con alambre muelle C, según normas DIN 17223C, y satisface plenamente los requerimientos que se le exigen en su funcionamiento. Posee alta capacidad al desgaste y su extremo biselado se remata en forma de media caña (6), adaptado mecánicamente a las contraformas establecidas en el rampón (1), concretamente en el rebaje cilíndrico (7) que el mismo presenta con este fin, de eje geométrico oblicuo como se observa claramente en la figura 7.For its part, the disconnect (2) is guided in the hole (5) of the rear heel of the barrel (4) (see figure 2), and It is preferably constructed with spring wire C, according to standards DIN 17223C, and fully satisfies the requirements that are they demand in its operation. It has high wear capacity and its bevelled end is finished in the form of half round (6), adapted mechanically to the counterforms established in the rampon (1), specifically in the cylindrical recess (7) that it presents with this end, of oblique geometric axis as clearly observed in Figure 7
El movimiento lineal de avance y retroceso del desconector (2), se realiza entre los topes marcados por el rebaje cajeado (8) existente en una zona paracentral del desconector (2), en el que juega el pasador fijo (9) dispuesto transversalmente en el tacón posterior del cañón (4). En las posiciones extremas se libera o fija al rampón (1).The linear movement of forward and reverse of the disconnector (2), is made between the stops marked by the recess recessed (8) existing in a paracentral zone of the disconnector (2), in which the fixed pin (9) arranged transversely in the rear heel of the barrel (4). In extreme positions you release or fix the rampon (1).
El rampón (1) se construye preferentemente con acero F-143 y después se le somete al tratamiento de temple, revenido y sulfinuzación anteriormente comentados, alcanzando así, conjuntamente con el desconector (2), la elevada capacidad al desgaste y al gripaje, requeridas. Este tratamiento térmico de sulfinuzación se realiza a 500ºC y aporta azufre y nitrógeno a la superficie tratada, y confiere las propiedades de antidesgaste, antigripaje, anticorrosión, elevada dureza superficial y lubrificación.Rampon (1) is preferably constructed with F-143 steel and then subjected to the treatment of quenching, tempering and sulfinuzación discussed above, thus achieving, together with the disconnector (2), the high wear and tear capacity required.
