Description
Abrazadera perfilada.Profile clamp.
La presente invención consiste en una abrazadera perfilada de las que se utilizan para unir tubos con brida y que en su forma tiene sus dos perfiles laterales ligeramente doblados hacia el interior, presentando una escotadura en su zona media y cuyos extremos terminan en sendas paredes enfrentadas entre sí, utilizando como medio de constreñido un tornillo que se ensarta en un orificio embutido y rosca en una tuerca tubular afianzada en uno de los extremos de la abrazadera.The present invention consists of a clamp profiled of those used to join flanged pipes and that in its shape it has its two slightly bent side profiles inwards, presenting a recess in its middle zone and whose ends end in each other's walls facing each other, using as a constricted means a screw that is skewered in a recessed hole and thread in a tubular nut secured in one end of the clamp.
Es amplia la utilización de las abrazaderas como medio de asegurar la unión de tubos y mangueras, existiendo de diferentes tipos y con distintos modos de apriete dependiendo de la naturaleza del objeto a constreñir, de las condiciones de su ubicación, de la dureza de los materiales asegurados y de la fuerza deseable para el cinchado de la abrazadera.The use of clamps is wide as means of ensuring the union of tubes and hoses, existing of different types and with different tightening modes depending on the nature of the object to be constrained, of the conditions of its location, hardness of insured materials and strength desirable for clamping the clamp.
La presente invención utiliza el tipo de brida conocido como perfilado porque presenta un perfil en sección en forma de "U" de fondo más o menos plano y brazos cortos que se obtiene por doblez de sus laterales hacia el interior.The present invention uses the flange type known as profiling because it presents a sectional profile in "U" shape with a more or less flat bottom and short arms obtains by bending its sides inwards.
La patente EP0636826 muestra en su figura 1 un perfil de lámina de abrazadera como el descrito en la invención, con dobleces laterales formando cavidad interior en forma de "U".EP0636826 shows in its figure 1 a clamp sheet profile as described in the invention, with lateral folds forming internal cavity in the form of "OR".
La patente española ES2161132 describe otra abrazadera perfilada que presenta tres escotaduras, una inferior o media y dos intermedias de ésta con los extremos del fleje. Dicha patente al igual que la anterior realiza el abrochado de la abrazadera mediante ganchos o puentes que se traban mutuamente al tensar un extremo y solaparlo con el otro.Spanish patent ES2161132 describes another profiled clamp that has three recesses, one lower or middle and two intermediate of this one with the ends of the strip. Bliss patent like the previous one makes the fastening of the clamp by hooks or bridges that lock each other to the tighten one end and overlap it with the other.
Uno de los inconvenientes de este tipo de abrazaderas es que la presión de cierre no se realiza de una forma lo suficientemente firme. El cierre se realiza por tensión, de golpe, al encajar ganchos de encastre, sin que exista una unión atornillada gradualmente tensable.One of the disadvantages of this type of clamps is that the closing pressure is not done in a way firm enough. The closing is done by tension, of hit, when fitting snap hooks, without a union screwed gradually tightened.
Además, en este tipo de abrazaderas cuya unión se realiza mediante ganchos que se engarzan, para realizar la unión se precisa el desalineado temporal de los extremos de la banda, provocando una desviación lateral de dichos extremos respecto del plano de la abrazadera que puede llegar a deformarla.In addition, in this type of clamps whose union It is done by hooks that are crimped, to make the union the temporary misalignment of the band ends is required, causing a lateral deviation of said ends with respect to the plane of the clamp that can deform it.
La patente europea EP0286561 que consiste en una abrazadera de las que se constriñe mediante un tornillo sujeto a una estructura afianzada en los extremos del fleje, muestra en su figura 1 los perfiles laterales de dicho fleje ligeramente curvados hacia adentro e incluso diversas escotaduras en su zona superior.European patent EP0286561 consisting of a clamp that is constrained by a screw attached to a structure secured at the ends of the strip, shows in its Figure 1 the lateral profiles of said slightly curved strap inward and even various recesses in your area higher.
Por otra parte la misma peticionaria de la presente patente describe en su patente europea EP0367169 una abrazadera de fleje laminar plano que se constriñe mediante tornillo. Los extremos doblados de dicho fleje albergan los orificios que sirven de sustentación del tornillo, disponiendo uno de ellos de una pequeña tuerca donde se rosca dicho tornillo, retenida por el extremo del fleje pero con alguna capacidad de movimiento para ajustarse a la variación en inclinación de la línea de apriete y avance del tornillo respecto del plano tangencial al fleje.On the other hand the same petitioner of the This patent describes in its European patent EP0367169 a flat laminar strap clamp that is constrained by screw. The folded ends of said strap house the holes that support the screw, providing one of them of a small nut where said screw is threaded, retained by the end of the strap but with some ability to movement to adjust to the inclination variation of the line of tightening and advancing the screw with respect to the tangential plane to the strip.
La patente francesa FR2779188 es una abrazadera de tornillo que en el ojal de roscado del tornillo emplaza una tuerca hexagonal libre que encaja en dicho orificio de roscado que también es hexagonal para evitar la rodadura de la tuerca cuando se realiza el apriete de la abrazadera.French patent FR2779188 is a clamp of screw that places a screw in the screw thread free hexagon nut that fits into said tapping hole that It is also hexagonal to prevent rolling of the nut when tighten the clamp.
Se ha observado que las abrazaderas conocidas, a pesar de sus buenos rendimientos, todavía pueden mejorarse para hacer frente a fuerzas más altas de constricción y evitar los problemas derivados de piezas sueltas en la estructura de la abrazadera que complican la labor de montado y que no ofrecen la máxima seguridad cuando se producen grandes fuerzas de apriete.It has been observed that the known clamps, to Despite their good performance, they can still be improved to cope with higher constriction forces and avoid problems derived from loose parts in the structure of the clamp that complicate the assembly work and that do not offer the Maximum safety when large clamping forces occur.
También se pretende evitar con la presente invención que en el cierre de este tipo de abrazaderas perfiladas se produzca una deformación de la misma, cuando por ejemplo deban engarzarse en tensión ganchos extremos de abrochado, desalineando sus extremos del plano inicial del fleje.It is also intended to avoid with this invention that in the closure of this type of profiled clamps deformation of the same occurs, for example when snap in tension clasped end hooks, misaligning its ends of the initial strip plane.
Finalmente otro propósito de la presente invención es proporcionar una abrazadera de tipo perfilado que permita un cierre gradual y progresivo de la abrazadera.Finally another purpose of the present invention is to provide a profile type clamp that allow a gradual and progressive closure of the clamp.
La presente invención pretende una mejora en el tipo de abrazaderas conocidas como perfiladas, es decir, con perfil de sus laterales creando una cavidad interior, de forma que permita su constreñido mediante un tornillo para obtener un apriete progresivo y gradual de la abrazadera, mejorando la sustentación del tornillo para hacer frente a las elevadas fuerzas de constricción que se aplicarán a dicha abrazadera y suprimiendo totalmente elementos sueltos del sistema de sustentación de la estructura del tornillo.The present invention seeks an improvement in the type of clamps known as profiled, that is, with profile of its sides creating an inner cavity, so that allow its constraint by means of a screw to obtain a tightening progressive and gradual clamp, improving lift of the screw to cope with the high forces of constriction that will apply to said clamp and suppressing totally loose elements of the lift system of the screw structure.
La abrazadera perfilada de la invención está formada por un fleje laminar con perfiles ligeramente curvados hacia adentro, creando una cavidad interior. En su zona inferior dispone de una escotadura.The profiled clamp of the invention is formed by a laminar strip with slightly curved profiles inward, creating an inner cavity. In its lower zone It has a recess.
Los extremos del fleje se proyectan hacia fuera y tiene sus lados doblados hacia el interior, albergando uno de dichos extremos una tuerca en forma de cilindro saliente por la cara exterior de dicho extremo. Dicha tuerca encaja en un orificio hexagonal y se ensambla mediante un remachado.The ends of the strap project outward and has its sides folded inward, housing one of said ends a protruding cylinder-shaped nut by the outer face of said end. Said nut fits in a hole hexagonal and assembled by riveting.
En el otro extremo hay dispuesto un orificio realizado por embutición que crea un pequeño soporte cilíndrico para el tornillo de apriete.At the other end there is a hole made by drawing that creates a small cylindrical support for the tightening screw.
Para una mejor interpretación del objeto de la invención se describe a continuación un caso de realización práctica, a título de ejemplo no limitativo de la misma, acompañándose de una hoja de dibujos en la que en la figura 1 se muestra un vista en perspectiva de una abrazadera según la invención, con su tornillo de apriete separado y en línea.For a better interpretation of the purpose of the invention described below a case of embodiment practice, by way of non-limiting example thereof, accompanied by a sheet of drawings in which figure 1 shows shows a perspective view of a clamp according to the invention, with its separate and in-line tightening screw.

La figura 4 y la figura 5 son sendas vistas frontales de cada uno de los extremos de la abrazadera, por la parte interior de la misma, mostrando la forma de sus respectivos orificios de paso del tornillo de apriete.Figure 4 and Figure 5 are views front of each end of the clamp, by the inside of it, showing the shape of their respective through holes of the tightening screw.
Consiste la invención en una abrazadera perfilada formada por un fleje laminar (1) enrollado sobre sí mismo y de extremos libres que terminan en testas planas (6 y 6') mutuamente enfrentadas para el paso de un tornillo de constricción (5), estando los laterales (3) de dicho fleje laminar (1) ligeramente curvados hacia el interior, formando una cavidad con segmento central (4), y presentando en la parte intermedia una escotadura (2) que proporciona flexibilidad para el ajuste al diámetro del tubo a constreñir.The invention consists of a clamp profiled formed by a laminar strip (1) wound on itself and of free ends that end in flat testes (6 and 6 ') mutually facing each other for the passage of a constriction screw (5), the sides (3) of said laminar strap (1) being slightly curved inward, forming a cavity with central segment (4), and presenting in the intermediate part a recess (2) that provides flexibility for adjustment to tube diameter to constrict.
En dichas testas (6 y 6') se ha practicado en sus laterales paralelos sendos dobleces (11 y 11') hacia el interior para dotar a dichas testas (6 y 6') de mayor inercia y resistencia a las elevadas fuerzas con que es constreñida la abrazadera.In these testas (6 and 6 ') it has been practiced in its parallel sides two folds (11 and 11 ') towards the interior to provide these testas (6 and 6 ') with greater inertia and resistance to the high forces with which the clamp.
En una de dichas testas (6') se ubica una tuerca cilíndrica (7), de una longitud mayor que una tuerca estándar, sujeta con un medio de vinculación permanente, tal cual un remache (8), en un orificio hexagonal (9) que impide movimientos rotacionales frente al giro del tornillo de constricción (5). Dicha tuerca cilíndrica proporciona un guiado al tornillo que aumenta el par de trabajo sin deformación de las testas (6 y 6').In one of these testas (6 ') a nut is located cylindrical (7), longer than a standard nut, fastened with a means of permanent bonding, such as a rivet (8), in a hexagonal hole (9) that prevents movements Rotational against the rotation of the constriction screw (5). Bliss cylindrical nut provides guidance to the screw that increases the working torque without deformation of the testes (6 and 6 ').
En la testa (6) del extremo opuesto existe practicado un orificio (10), realizado por embutición, creando un pequeño cilindro de sustentación (12) de dicho tornillo de constricción (5). Dicho orificio embutido no sólo sirve para proporcionar una guía recta para dicho tornillo de apriete, sino que además dota de mayor inercia contra la deformación y mayor rigidez a dicha testa (6), permitiendo un par de trabajo mayor sin deformarla.In the testa (6) of the opposite end there is practiced a hole (10), made by drawing, creating a small support cylinder (12) of said screw of constriction (5). Said hole not only serves to provide a straight guide for said tightening screw, but which also provides greater inertia against deformation and greater rigidity to said testa (6), allowing a greater work torque without warp it.
Se sobreentiende que en el presente caso serán variables cuantos detalles no cambien o alteren en lo sustancial la presente invención.It is understood that in the present case they will be variables how many details do not change or substantially alter the present invention
