Device for tensioning elements flexible wrapped on pulleys, where a pulley (4) is in conditions for carrying out relative translation movements and perpendicular to a tree (8) on which it is installed rotating way, respectively between an advanced position, where the minimum tension of the flexible element (2) associated with the pulley (4), and a retracted position, where tensioning occurs maximum of the flexible element (2), the tensioning means being provided to cause said pulley translation movements (4) with respect to the shaft (8), said tensioning means being housed inside an opening (12) in a central area of the pulley (4), said opening (12) being delimited, in the plane in which rest the pulley (4), by the mainly annular extension of a bearing (13) on which said pulley (4) is crimped, and transversely to the plane on which the pulley (4) rests, by the two opposite surfaces of the pulley (4), said opening (12) therefore having a fixed position with respect to the movement rotating the pulley (4) around said shaft (8), characterized by the fact that said tensioning means comprise at least one sliding skate (16) that is integral to the tree (8) and which has, associated with it, at least one hydraulic jack (19) connected at one end to said bearing (13) and at the other end to said sliding skate (16), the fluid under pressure being forced to circulate inside a chamber (23) inside of the hydraulic jack (19), so as to cause translation relative of said sliding skate (16) with respect to said bearing (13) which results in the relative translation of said pulley (4) with respect to said tree (8).
Éste es un sistema de tensado vinculado a las poleas tensoras y de muy complicada realización, al tener que incluir un gato hidráulico (19) por polea y todo ello en pequeños espesores de poleas una junto a la otra. No es, por tanto, un sistema desvinculado de las poleas tensoras que permita de esta forma la variación de la posición, movilidad y el reposicionado de cada uno de los volantes tensores, para modificar el espesor de las losas a cortar con una operación simple y rápida en maquinas de corte de piedra con múltiples hilos, sin tener que desconectar los pistones hidráulicos de tensado al estar éstos situados en posiciones fijas a un soporte principal como el que preconiza la invención presentada.This is a tensioning system linked to the tension pulleys and very complicated realization, having to include a hydraulic jack (19) by pulley and all in small pulley thicknesses next to each other. It is not, therefore, a unlinked system of tension pulleys that allows this it forms the variation of the position, mobility and repositioning of each of the tension wheels, to modify the thickness of the slabs to cut with a simple and fast operation in machines of stone cutting with multiple threads, without having to disconnect the hydraulic tensioning pistons being these located in fixed positions to a main support such as the one recommended by the invention presented.
Concluimos, pues, que se hace necesaria la existencia de un sistema que permita la independencia del sistema de tensado, desvinculándolo de las poleas tensoras y permitiendo de esta forma la variación de la posición, movilidad y el reposicionado de cada uno de los volantes tensores, permitiendo modificar el espesor de las losas a cortar con una operación simple y rápida en maquinas de corte de piedra con múltiples hilos, sin tener que desconectar los pistones hidráulicos de tensado al estar éstos situados en posiciones fijas a un soporte principal.We conclude, then, that the existence of a system that allows the independence of the system of tensioned, detaching it from the tension pulleys and allowing this way the variation of position, mobility and repositioning of each of the tension wheels, allowing to modify the thickness of the slabs to be cut with a simple and fast operation in stone cutting machines with multiple threads, without having to disconnect the hydraulic tensioning pistons when they are located in fixed positions to a main support.
Dispositivo de tensado en maquinas de corte de piedra con múltiples hilos que permite la variación de la posición, movilidad y el reposicionado de cada uno de los volantes tensores, modificando el espesor de las losas a cortar.Tensioning device in cutting machines multi-threaded stone that allows position variation, mobility and repositioning of each of the tension wheels, modifying the thickness of the slabs to be cut.
La utilización del hilo diamantado en las labores de aferramiento primario se está empleando en este sector desde hace varios años y dicho alambre se aplica sobre maquinas conocidas, normalmente conformadas por dos poleas, una de ellas motorizada (motriz) y otra conducida, sobre las que se instala el alambre formando un bucle cerrado con el que se efectúan los diferentes cortes sobre los bloques de piedra. Alternativamente, existen maquinas que emplean varios hilos diamantados, los cuales se montan sobre volantes o tambores con múltiples canales o conformadas por múltiples poleas, sobre las que se montan los diferentes hilos con el objeto de realizar múltiples cortes paralelos sobre los bloques pétreos obteniendo así unas producciones significativas.The use of diamond wire in Primary clinging work is being used in this sector for several years and said wire is applied on machines known, usually made up of two pulleys, one of them motorized (motor) and another driven, on which the wire forming a closed loop with which the Different cuts on the stone blocks. Alternatively, there are machines that use several diamond wires, which are mounted on flyers or drums with multiple channels or shaped by multiple pulleys, on which the different threads are mounted in order to make multiple parallel cuts on the Stone blocks thus obtaining significant productions.
El problema técnico a solucionar surge a la hora de realizar el correcto tensado de los hilos; un segundo problema técnico mas significativo es el de variar de forma fácil la posición de los pares de hilos para la obtención de distintos espesores en la elaboración de losas a cortar por el hilo.The technical problem to solve arises at the time to make the correct tensioning of the threads; a second problem most significant technical is to easily change the position of the pairs of threads to obtain different thicknesses in the elaboration of slabs to cut by the thread.
El sistema que la invención preconiza tiene por objeto la independencia del sistema de tensado, desvinculándolo de las poleas tensoras y permitiendo de esta forma la variación de la posición, movilidad y el reposicionado de cada uno de los volantes tensores, permitiendo modificando el espesor de las losas a cortar con una operación simple y rápida en maquinas de corte de piedra con múltiples hilos, sin tener que desconectar los pistones hidráulicos de tensado al estar éstos situados en posiciones fijas a un soporte principal.The system that the invention advocates has for object the independence of the tensioning system, decoupling it from the tensioning pulleys and thus allowing the variation of the position, mobility and repositioning of each of the flyers tensioners, allowing modifying the thickness of the slabs to be cut With a simple and fast operation in stone cutting machines with multiple wires, without having to disconnect the hydraulic pistons of tensioning when these are located in fixed positions to a support principal.

El dispositivo descrito está compuesto por un soporte o cuerpo principal (1) que va a ser el encargado de soportar los esfuerzos producidos por la tensión de los hilos, además del peso propio de todos los elementos.The described device is composed of a support or main body (1) that will be in charge of supporting the efforts produced by the tension of the threads, in addition to the own weight of all the elements.
Sobre este cuerpo se alojan en posiciones fijas predeterminadas una cantidad de pistones (2) independientes que son los encargados de desplazar las poleas tensoras y dar por tanto la tensión a cada uno de los hilos.On this body they stay in fixed positions predetermined a number of independent pistons (2) that are those responsible for displacing the tension pulleys and therefore giving the tension to each of the threads.
El mismo cuerpo es el encargado de soportar a cada una de las poleas gracias a unas horquillas (3) que se deslizan sobre el cuerpo con el objeto de fijar o variar el espesor de corte entre cada par de hilos.The same body is responsible for supporting each of the pulleys thanks to some forks (3) that slide on the body in order to set or vary the cutting thickness between each pair of threads.
Sobre estas horquillas se alojan sendos rodamientos lineales (4) perpendiculares al cuerpo principal que son los encargados de facilitar el movimiento de traslación de las diferentes poleas y soportar los esfuerzos radiales y axiales producidos por éstos.On these forks are lodged each other linear bearings (4) perpendicular to the main body that are those responsible for facilitating the movement of the different pulleys and withstand radial and axial stresses produced by these.
Dichas guías se unen al núcleo (5) de cada polea que es el que contacta con los pistones dispuestos sobre el cuerpo principal con objeto de producir indirectamente el desplazamiento de cada polea para efectuar el tensado de cada uno de los hilos.Said guides are attached to the core (5) of each pulley which is the one that contacts the pistons arranged on the body principal in order to indirectly produce the displacement of each pulley to tighten each of the threads.
Sobre este cuerpo se monta un rodamiento (6) que a su vez soporta cada polea tensora (7).A bearing (6) is mounted on this body that in turn it supports each tension pulley (7).
Los pistones (2) se encuentran dispuestos de
forma tal que independientemente de donde se sitúe cada una de las
poleas tensoras (7) en función del espesor de trabajo deseado para
las losas a obtener, actúan un mínimo de tres unidades de estos
pistones por cada uno de los volantes hilos a tensar. Ello nos
permite además reducir notablemente la presión de trabajo necesaria
en el sistema hidráulico hasta los 30-35 bares para
ejecutar el tensado final de cada uno de los hilos; con los sistemas
tradicionales de tensado la presión de trabajo requerida oscila
entre los 140 y los 160 bares, al ser muy reducido el espacio
disponible para situar todos los elementos necesarios (inferior
a
30 mm).The pistons (2) are arranged in such a way that regardless of where each of the tension pulleys (7) is located depending on the desired thickness of work for the slabs to be obtained, a minimum of three units of these pistons act for each One of the flying threads to tighten. This also allows us to significantly reduce the necessary working pressure in the hydraulic system to 30-35 bars to execute the final tensioning of each of the wires; With the traditional tensioning systems, the required working pressure ranges between 140 and 160 bar, since the space available to place all the necessary elements (less than
30 mm)
