Description

Dispositivo de presión neumática autónomo.Autonomous pneumatic pressure device.

Objeto de la invenciónObject of the invention

La presente solicitud de Patente de Invención tiene por objeto el registro de un dispositivo de presión neumática autónomo que incorpora notables innovaciones y ventajas frente a los actuales medios de suministro de presión neumática o máquinas que funcionan con presión neumática existentes.The present invention patent application Its purpose is to register a pneumatic pressure device autonomous that incorporates notable innovations and advantages over the current means of supply of pneumatic pressure or machines that work with existing pneumatic pressure.

Más concretamente la nueva invención comprende un dispositivo de presión neumática constituida por un depósito o pequeño recipiente que comprende un gas a alta presión, ya sea licuado o comprimido, el cual se puede liberar a través de un regulador de presión que adapta la presión interna a la presión de trabajo y una válvula de paso o accionamiento del dispositivo, acoplable a prensas, mordazas y otras máquinas neumáticas en las que el factor importante es la presión del circuito para funcionar, aportándoles un factor de portabilidad dado su pequeño tamaño y ligero peso.More specifically, the new invention comprises a pneumatic pressure device consisting of a reservoir or small vessel comprising a high pressure gas, either liquefied or compressed, which can be released through a pressure regulator that adapts the internal pressure to the pressure of work and a valve of passage or actuation of the device, attachable to presses, jaws and other pneumatic machines in the that the important factor is the circuit pressure to operate, giving them a portability factor given their small size and light weight

Antecedentes de la invenciónBackground of the invention

Actualmente en el mercado hay disponibles una gran variedad de máquinas neumáticas que funcionan total o parcialmente con aire a presión, tal como prensas, pinzas, remachadoras, turbinas, sistemas de automatismos y otros.A market is currently available wide variety of pneumatic machines that work total or partially with pressurized air, such as presses, tweezers, riveters, turbines, automation systems and others.

Estas máquinas obtienen el aire a presión, que es la energía que las mueve, de compresores que comprimen el aire ambiente hasta una presión adecuada. Mediante las canalizaciones adecuadas, hasta las herramientas manuales o fijas. Esto se realiza porque estos compresores asociados a un motor eléctrico o de combustión son voluminosos y difíciles de mover, sobre todo si comprenden un calderín de almacenamiento de aire a presión. Por lo tanto no son utilizables como herramientas totalmente portátiles o autónomas.These machines get the air under pressure, which is the energy that moves them, of compressors that compress the air ambient to adequate pressure. Through the pipes suitable, even manual or fixed tools. This is done because these compressors associated with an electric motor or of combustion are bulky and difficult to move, especially if They comprise a pressure air storage boiler. For the both are not usable as fully portable tools or autonomous.

Son conocidos los extintores de tipo polvo que comprenden además del cuerpo de almacenamiento del polvo o agente extintor, un depósito de gas a presión independiente, conocido como torpedo. Tal como se ha mencionado, este torpedo comprende el aire o gas a presión que se necesita para impulsar el polvo en caso de usarse el extintor. Para ello se abre la válvula del torpedo y el gas a presión pasa a llenar todo el cuerpo que tiene el polvo, ejerciendo así una fuerza para que este salga expulsado por la boquilla de salida. Este tipo de dispositivo es de un solo uso, ya que una vez abierto el torpedo hay que recambiarlo para poder volver a utilizar el extintor.Powder type fire extinguishers are known that comprise in addition to the storage body of the powder or agent fire extinguisher, an independent pressure gas tank, known as torpedo. As mentioned, this torpedo comprises the air or gas under pressure that is needed to boost dust in case of use the extinguisher To do this, the torpedo valve is opened and the gas under pressure happens to fill the whole body that has the dust, thus exerting a force so that it is expelled by the outlet nozzle This type of device is for single use, since Once the torpedo is opened, it must be replaced to be able to reuse the extinguisher.

También son conocidas las pistolas y armas de gas o aire comprimido, en las que el arma comprende un depósito o recipiente con un gas comprimido, que comunica con un percutor de la bala o proyectil, formado por un cilindro de simple efecto dotado de un muelle de gran constante de expansión. En estas pistolas y armas el aire empuja el percutor para comprimir un muelle, el cual impulsa la bala al oprimir el gatillo. Una vez realizado el disparo la presión del gas contenido en el depósito hace retroceder el percutor o cilindro hasta un nuevo disparo de forma automática. Dadas estas condiciones la presión del gas del depósito va descendiendo, afectando a la velocidad de retroceso.Gas guns and weapons are also known. or compressed air, in which the weapon comprises a reservoir or container with a compressed gas, which communicates with a firing pin of the bullet or projectile, formed by a single-acting cylinder endowed  of a spring of great expansion constant. In these guns and guns the air pushes the firing pin to compress a spring, which propel the bullet by pressing the trigger. Once shot the gas pressure contained in the tank pushes back the firing pin or cylinder until a new shot automatically. Given these conditions the gas pressure in the tank goes descending, affecting the recoil speed.

Descripción de la invenciónDescription of the invention

El dispositivo de presión neumática autónomo objeto del presente registro, se caracteriza porque permite que máquinas que hasta ahora se tenían que usar de forma fija asociada con un compresor, que es difícilmente transportable, se puedan llevar a realizar tareas de forma independiente. En efecto la nueva invención libera la autonomía o posibilidad de uso por parte de profesionales tales como instaladores de carpintería metálica, mecánicos y otros que usan muchas veces máquinas que en todo o en parte son de accionamiento neumático, tales como prensas, cizallas neumáticas, pinzas de sujeción o sierras de corte entre otros. De forma general, en estos casos, estos profesionales se ven obligados a llevar parte del trabajo nuevamente al taller, cargar con un voluminoso compresor que depende de un enchufe conectado a la red eléctrica o utilizar herramientas eléctricas no tan eficaces y ligeras como las neumáticas.The autonomous pneumatic pressure device object of this record, is characterized in that it allows machines that until now had to be used in a fixed way associated with a compressor, which is hardly transportable, can be Carry out tasks independently. Indeed the new invention releases the autonomy or possibility of use by professionals such as metalwork installers, mechanics and others who often use machines that in all or in part are pneumatically operated, such as presses, shears pneumatic, clamps or cutting saws among others. From In general, in these cases, these professionals are forced to take part of the work back to the workshop, load with a bulky compressor that depends on a plug connected to the network power or use power tools not as effective and Light as pneumatic.

El objetivo de la nueva invención es obtener un dispositivo con unos componentes pequeños, compactos y ligeros, de forma que se puedan asociar con facilidad con una herramienta neumática proveyéndole de la autonomía suficiente y prescindiendo de compresores y aparatos similares que son voluminosos y difíciles de mover.The objective of the new invention is to obtain a device with small, compact and lightweight components of so that they can be easily associated with a tool pneumatic providing sufficient autonomy and without of compressors and similar devices that are bulky and difficult of moving

El dispositivo comprende principalmente un depósito de un gas comprimido o licuado, de forma que en su interior existe una muy alta presión. Este depósito está asociado con un regulador de presión a su salida de forma que la presión interior del depósito es rebajada a una presión convencional de trabajo para las herramientas. Este regulador además tiene la misión de estabilizar dicha presión de trabajo, manteniéndola constante, aunque la presión en el interior del depósito vaya descendiendo hasta que se igualen, momento en el que es necesario recargar el depósito, o cambiarlo por otro lleno, por agotamiento. A la salida del depósito se encuentra una válvula de corte que determina si el dispositivo suministra la presión o no a la máquina. Incluso esta válvula puede comprender un obús que la abre en el momento que el dispositivo se enchufa o acopla a la herramienta o máquina de forma automática. Adicionalmente existe una válvula de mando pulsante, que puede ser de accionamiento directo o remoto, mediante un electromecanismo o electroválvula, un accionamiento mecánico por cable o similar. Esta válvula de mando está dispuesta principalmente en la herramienta o máquina, pero opcionalmente puede estar dispuesta en el dispositivo por necesidades técnicas.The device mainly comprises a deposit of a compressed or liquefied gas, so that in your inside there is a very high pressure. This deposit is associated with a pressure regulator at its outlet so that the pressure inside the tank is lowered to a conventional pressure of I work for the tools. This regulator also has the mission of stabilizing said working pressure, maintaining it constant, even if the pressure inside the tank goes descending until they match, at which point it is necessary recharge the deposit, or exchange it for a full one, due to exhaustion. At the outlet of the tank is a shut-off valve that determines whether the device supplies the pressure or not to the machine. Even this valve can comprise a howitzer that opens it at the time the device is plugged in or attached to the tool or machine automatically. Additionally there is a pulsating control valve, which can be operated direct or remote, through an electromechanism or solenoid valve, a mechanical cable drive or similar. This control valve It is arranged primarily on the tool or machine, but optionally it can be arranged in the device by Technical requirements.

El gas utilizado en el depósito puede ser de cualquier naturaleza que permita su uso con herramientas neumáticas sin deteriorarlas. Sin embargo es aconsejable el uso de aquellos gases y fluidos que tengan una alta compresibilidad, tal como el dióxido de carbono (CO_{2}) o similar que se puede suministrar con facilidad en depósitos discretos hasta una presión de 100 bares. Esto es importante, teniendo en cuenta que la presión de trabajo puede estar al entorno de los 2 a los 8 bares, por ejemplo. Otro tipo de fluido de potencia que se puede utilizar son los gases licuados, que están almacenados de forma líquida con una pequeña bolsa de gas, pero que a medida que la parte gaseosa se va extrayendo se produce la evaporación del líquido, manteniendo nuevamente la presión interior por equilibrio. Por necesidades de la herramienta o utilización, el gas puede ir mezclado con aceite o lubricante.The gas used in the tank can be any nature that allows its use with pneumatic tools Without deteriorating them. However it is advisable to use those gases and fluids that have high compressibility, such as carbon dioxide (CO2) or the like that can be supplied easily in discrete tanks up to a pressure of 100 pubs. This is important, given that the pressure of Work can be around 2 to 8 bars, for example. Another type of power fluid that can be used is gases smoothies, which are stored in liquid form with a small gas bag, but as the gas part goes extracting the evaporation of the liquid, maintaining again the internal pressure by equilibrium. For needs of the tool or use, the gas can be mixed with oil or lubricant.

Dada la aplicación que se le confiere al dispositivo se ha previsto que el depósito sea de un tamaño contenido, permitiendo que se pueda acoplar a la herramienta como un cartucho y transportado por el usuario a modo de herramienta manual convencional.Given the application given to the device is expected to have a deposit of one size content, allowing the tool to be attached as a cartridge and transported by the user as a tool conventional manual.

Dada la naturaleza de la invención, el presente dispositivo es más adecuado para máquinas neumáticas en las que las necesidades de funcionamiento principales sea la presión y no el caudal. Conectar el dispositivo a una máquina que necesita un gran caudal o consumo de gas presurizado puede agotar con facilidad el depósito presurizado. Sin embargo, las máquinas del tipo que comprenden cilindros neumáticos de corto recorrido y similares, los cuales no son accionados una gran cantidad de veces en un corto espacio de tiempo, tales como herramientas de golpeteo, son idóneas para su uso. Esto es debido a que el accionamiento de la máquina no implica una gran descarga del depósito.Given the nature of the invention, the present device is more suitable for pneumatic machines in which the main operating needs be the pressure and not the flow. Connect the device to a machine that needs a large flow or consumption of pressurized gas can easily deplete the pressurized deposit. However, machines of the type that They include short-distance pneumatic cylinders and the like, which are not operated a large number of times in a short space of time, such as tapping tools, are suitable for use This is because the machine drive does not It implies a large discharge from the deposit.

En caso necesario se ha previsto que una máquina pueda estar asociada a más de un dispositivo como fuente de energía. En efecto, mediante el uso de un distribuidor o similar existente en la máquina o independiente se puede asociar más de un dispositivo en batería, aumentando la autonomía y capacidad de funcionamiento.If necessary, it is planned that a machine may be associated with more than one device as a source of Energy. Indeed, through the use of a distributor or similar existing in the machine or independent can be associated more than one battery device, increasing autonomy and ability to functioning.
