Description
Dispositivo de medición en máquinas de corte por chorro de agua.Measuring device in cutting machines by Waterjet.
La presente invención se refiere a un dispositivo de medición en máquinas de corte por chorro de agua, previsto concretamente para llevar a cabo la medición y control de la distancia entre la boquilla de salida del chorro de agua y la pieza a cortar.The present invention relates to a measuring device in water jet cutting machines, specifically planned to carry out the measurement and control of the distance between the nozzle of the water jet and the piece to cut.
El objeto de la invención es conseguir una medición y por lo tanto un control totalmente automáticos de la distancia entre boquilla de salida del chorro de agua y pieza a cortar y evitar con ello errores por salpicaduras u otros obstáculos originados, por ejemplo, en el arranque de material correspondiente a la pieza que se está cortando.The object of the invention is to achieve a measurement and therefore a fully automatic control of the distance between water jet outlet nozzle and part a cut and avoid errors by splashing or other obstacles originated, for example, in the starting of corresponding material to the piece that is being cut.
Se conocen máquinas que utilizan un chorro de agua o chorro de agua con abrasivo para cortar determinadas piezas, como pueden ser piezas de acero duro.Machines are known that use a jet of water or water jet with abrasive to cut certain parts, such as hard steel pieces.
Es evidente que cuando el chorro de agua que realiza el corte está trabajando, se produce el desprendimiento de partículas del material a cortar, material abrasivo, salpicaduras, de manera que el ambiente que rodea al chorro de agua es un ambiente sucio, es decir con partículas distribuidas aleatoriamente.It is evident that when the water jet that make the cut is working, the detachment of particles of the material to be cut, abrasive material, splashes, so that the environment surrounding the water jet is an environment dirty, that is to say with randomly distributed particles.
Durante las operaciones de corte es necesario llevar a cabo una medición con el fin de controlar la distancia de la boquilla de salida del chorro de agua y la pieza a cortar, para conseguir el máximo rendimiento y eficacia en el corte.During cutting operations it is necessary carry out a measurement in order to control the distance of the water jet outlet nozzle and the part to be cut, for achieve maximum performance and efficiency in cutting.
Hasta el momento, el control de la distancia del chorro de agua sobre la pieza a cortar se lleva a cabo por medios mecánicos, tales como palpadores mecánicos, con lo que los errores en la medición son muy frecuentes, debido precisamente a la presencia de los residuos o partículas que se producen durante la operación de corte.So far, the distance control of the water jet on the piece to be cut is carried out by means mechanics, such as mechanical probes, bringing errors in the measurement they are very frequent, due precisely to the presence of residues or particles that are produced during cutting operation
Por otra parte, si los medios mecánicos o palpadores se sitúan a la altura de la pieza a cortar, puede que la boquilla de corte no choque con el obstáculo y sí lo haga el palpador, causando al final una avería.On the other hand, if the mechanical means or probes are placed at the height of the piece to be cut, the cutting nozzle does not collide with the obstacle and yes the probe, ultimately causing a breakdown.
El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, en base a una solución sencilla pero enormemente eficaz.The device that has been recommended has been designed to solve the problem described above, in based on a simple but enormously effective solution.
Más concretamente, el dispositivo de la invención se basa en que la medida de la distancia se consigue mediante medidores de ultrasonidos, pudiendo incluir un único medidor o sensor ultrasónico montado sobre el propio cabezal de la máquina portadora de la boquilla de salida del chorro de agua como medio de corte, pudiendo complementarse con otros medidores ultrasónicos o sensores, en un número indeterminado y previstos posteriormente al cabezal de la propia máquina.More specifically, the device of the invention is based on the fact that distance measurement is achieved using ultrasonic meters, and may include a single ultrasonic meter or sensor mounted on the head of the water jet outlet nozzle carrier machine as cutting medium, being able to complement with other meters ultrasonic or sensors, in an indeterminate number and provided subsequently to the head of the machine itself.
Además, el haz correspondiente al medidor o
sensor ultrasónicos, pudiendo también ser ópticos, discurre alojado
en el seno de un segundo chorro de agua cuya función no es
precisamente la de llevar a cabo el corte de la pieza, sino actuar
como guía para el haz de ultrasonidos y evitar que sobre el mismo
lleguen las salpicaduras o partículas obtenidas por desprendimiento
de material en el corte sobre la pieza, que se realiza mediante el
chorro de agua que sale por la
boquilla correspondiente.In addition, the beam corresponding to the ultrasonic meter or sensor, which can also be optical, runs inside a second water jet whose function is not precisely to carry out the cutting of the piece, but to act as a guide for the beam of ultrasound and avoid that on it the splashes or particles obtained by detachment of material in the cut on the piece arrive, which is carried out by means of the water jet that comes out of the
corresponding nozzle
Teniendo en cuenta que si se trata de cortar una pieza de superficie plana no se presenta ningún tipo de problema, ya que se dispone a una distancia fija y todo el corte se realiza a dicha distancia, sin embargo cuando la pieza a cortar no es plana, entonces es necesario establecer un control de la distancia de la boquilla de corte. Puesto que la pieza a cortar puede moverse durante el corte y quedar en posición más elevada, pudiendo ser causa de rotura de la boquilla en ambos casos.Considering that if it comes to cutting a flat surface piece does not present any problem, since which is arranged at a fixed distance and the entire cut is made at said distance, however when the piece to be cut is not flat, then it is necessary to establish a distance control of the cutting nozzle Since the piece to be cut can move during cutting and being in a higher position, being able to be cause of breakage of the nozzle in both cases.
Teniendo además en cuenta que la distancia de la boquilla de salida del chorro de agua de corte a la pieza a cortar es muy pequeña, es evidente que se requiere un control automático para la parada o elevación de dicha boquilla, lo cual se consigue mediante los medidores ultrasónicos objeto de la invención. Además, mediante dichos medidores ultrasónicos se puede conocer el espesor de la pieza a cortar, haciendo una comparativa entre la emisión del haz ultrasónico y la recepción de la señal, con la particularidad de que un segundo o tercer medidor ultrasónico, situado por detrás del corte o fresado, proporcionará la profundidad de corte o fresado que se está efectuando.Also taking into account that the distance of the water jet outlet nozzle to the part to be cut It is very small, it is obvious that automatic control is required for stopping or lifting said nozzle, which is achieved by the ultrasonic meters object of the invention. Further, by means of said ultrasonic meters the thickness can be known of the piece to be cut, making a comparison between the emission of the ultrasonic beam and signal reception, with the particularity of than a second or third ultrasonic meter, located behind the cutting or milling, will provide the depth of cut or milling that It is taking place.
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un único dibujo en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a single drawing where with an illustrative and non-limiting nature, what has been represented next:
La figura única representada en la hoja de planos referida corresponde a una representación esquemática del corte que se realiza sobre una pieza mediante chorro de agua, incluyendo los sensores o medidores ultrasónicos guiados por un segundo chorro de agua como novedad de la invención.The unique figure represented on the sheet referred planes correspond to a schematic representation of the cut that is made on a piece by means of water jet, including ultrasonic sensors or meters guided by a second water jet as a novelty of the invention.
Como se puede ver en la figura referida, el dispositivo de medición objeto de la invención es aplicable en máquinas de corte por chorro de agua, incluyendo dichas máquinas un cabezal (1) portador de la correspondiente boquilla (2) a través de la cual sale el chorro de agua (3) previsto para realizar el corte (4) en una pieza (5) con un grosor determinado, existiendo una distancia concreta y determinada y que aparece acotada con la referencia (6) entre la salida de la boquilla (2) del chorro de agua (3) y la propia pieza (5) a cortar.As you can see in the referred figure, the measuring device object of the invention is applicable in water jet cutting machines, including said machines a head (1) carrier of the corresponding nozzle (2) through which leaves the water jet (3) provided for cutting (4) in a piece (5) with a certain thickness, there is a concrete and determined distance and that appears bounded with the reference (6) between the nozzle outlet (2) of the water jet (3) and the piece itself (5) to be cut.
Pues bien, la novedad de la invención es que la medición de la distancia anteriormente comentada se efectúa mediante un dispositivo medidor o sensor ultrasónico (7) en combinación con un chorro de agua (8) distinto al chorro de corte (3), de manera que ese chorro de agua (8) constituye el medio a través del cual discurre el haz del sensor o dispositivo ultrasónico de medición (7), quedando dicho haz protegido contra salpicaduras y partículas que se desprenden en la operación de corte propiamente dicha.Well, the novelty of the invention is that the measurement of the aforementioned distance is made by a measuring device or ultrasonic sensor (7) in combination with a water jet (8) other than the cutting jet (3), so that that water jet (8) constitutes the means through which the sensor beam or ultrasonic measuring device runs (7), said beam being protected against splashes and particles that are detached in the actual cutting operation.
Además del sensor ultrasónico (7) puede haber otros sensores ultrasónicos (9) previstos en el propio cabezal (1) o con posterioridad al mismo, es decir por detrás del corte (4) que se está realizando, de manera que esos sensores ultrasónicos (9) proporcionarán la profundidad del corte (4) que se está efectuando.In addition to the ultrasonic sensor (7) there may be other ultrasonic sensors (9) provided in the head itself (1) or after it, that is, behind the cut (4) that is performing, so that those ultrasonic sensors (9) will provide the depth of cut (4) that is being effecting
En base al dispositivo referido, se consigue controlar la distancia (6) entre la boquilla (2) de salida del chorro de agua (3) y la propia pieza (5) a cortar, además de evitar la colisión contra la propia pieza a cortar (5), ya que ésta durante la operación de corle puede moverse y constituir un obstáculo para la propia boquilla (2), que podría chocar contra dicha pieza (5) y deteriorar o romper la propia boquilla (2).Based on the referred device, it is achieved check the distance (6) between the nozzle (2) of the outlet of the water jet (3) and the piece (5) to be cut, in addition to avoiding the collision against the piece to be cut (5), since this during the corle operation can move and constitute an obstacle to the nozzle itself (2), which could collide with said part (5) and damage or break the nozzle itself (2).
Además, en virtud de la medición que proporcionan los sensores o medidores ultrasónicos referidos, se puede llevar a cabo un posicionado correcto de la pieza a cortar (5), así como controlar el espesor de la misma, además de permitir la indicación de si el ángulo es el correcto o no en aquellos casos en que los cortes no sean perpendiculares respecto de la pieza que se está cortando.In addition, by virtue of the measurement that they provide the referred ultrasonic sensors or meters, it it can carry out a correct positioning of the piece to cut (5), as well as controlling its thickness, in addition to allowing the indication of whether the angle is correct or not in those cases in which the cuts are not perpendicular with respect to the piece that It is being cut.
