DESCRIPCIÓN Objeto de Ia invenciónDESCRIPTION Object of the invention
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo para refrigerar brocas que tiene como objetivo la refrigeración de brocas, esencialmente cuando se trabajan materiales duros, como por ejemplo materiales porcelánicos, en los que Ia broca sufre un elevado desgaste. Antecedentes de Ia invención En Ia actualidad, dentro de los métodos y dispositivos utilizados para Ia refrigeración de brocas suele recurrirse a dispositivos que imprimen un chorro de agua o cualquier otro fluido refrigerante sobre Ia herramienta de corte o broca para disminuir Ia temperatura de ésta. Esta forma de reducir Ia temperatura tiene el inconveniente de necesitar un sistema de impulsión de ese fluido repercutiendo en el coste de realizar la operación, no siendo rentable cuando se realiza un uso particular.The present invention, as expressed in the statement of this specification, refers to a device for cooling bits that aims to cool bits, essentially when working hard materials, such as porcelain materials, in which the drill bit suffers high wear. BACKGROUND OF THE INVENTION At present, within the methods and devices used for the cooling of drill bits, devices that print a water jet or any other cooling fluid on the cutting tool or drill bit are used to reduce the temperature thereof. This way of reducing the temperature has the disadvantage of needing a system of impulsion of that fluid having an impact on the cost of carrying out the operation, not being profitable when a particular use is made.

Está construido de un material que permita obtener caras lisas o al menos una cara lisa que coincidirá con Ia que apoyará sobre Ia superficie de Ia pieza a perforar, ya que lo que se pretende es que dicha cara realice un cierre aproximadamente estanco con Ia superficie a perforar. Evidentemente el cuerpo principal podrá presentar cualquier otra configuración diferente. El dispositivo dispondrá de un compartimento hueco en su interior que se rellenará con el correspondiente líquido refrigerante.In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a device for cooling bits that is characterized in that it is determined from a main body, essentially prismatic-rectangular, which is of sufficient dimensions to be able to hold it with your hand while performing the drilling operation. It is constructed of a material that allows to obtain smooth faces or at least one smooth face that will coincide with the one that will rest on the surface of the piece to be drilled, since what is intended is that said face make an approximately sealed seal with the surface to be punch out. Obviously the main body may present any other different configuration. The device will have a hollow compartment inside that will be filled with the corresponding coolant.
Este compartimento dispondrá en uno de sus extremos de dos aberturas comunicadas entre sí y cada una de las cuales desembocará en Ia cara respectiva del prisma que atravesará Ia broca precisamente en correspondencia con dichas aberturas.This compartment will have at one of its ends two openings communicated with each other and each of which will flow into the respective face of the prism that will pass through the drill bit precisely in correspondence with said openings.
La abertura enfrentada con Ia superficie a taladrar tendrá un tamaño suficiente para cubrir Ia zona de perforación, permitir Ia extracción del polvo proveniente de Ia perforación y tener comunicados, en todo momento, Ia broca y el líquido refrigerante. Esta abertura puede ser rodeada por una junta tórica o similar, que ayude a conseguir Ia estanqueidad buscada.The opening facing the surface to be drilled will be of sufficient size to cover the drilling area, allow the extraction of the dust from the drilling and have communications, at all times, the drill bit and the coolant. This opening can be surrounded by an O-ring or similar, which helps to achieve the desired seal.
En cambio, Ia otra abertura pareja, implementada en Ia cara del prisma opuesta, se ajustará aproximadamente al tamaño de Ia broca, pudiendo disponer sistema de rodamientos, que eviten el rozamiento entreOn the other hand, the other even opening, implemented in the face of the opposite prism, will be adjusted approximately to the size of the drill bit, being able to have a bearing system that prevents friction between
Ia broca y las paredes de dicha abertura.The drill and the walls of said opening.
Para Ia utilización del dispositivo se rellenará el compartimento interno con un líquido refrigerante, apoyándose después sobre Ia superficie a practicar el taladro con Ia cara que posee Ia abertura mayor y, se presionará contra dicha superficie, para posteriormente, introducir Ia broca a través de las aberturas y realizar Ia correspondiente perforación.For the use of the device, the internal compartment will be filled with a coolant, then resting on the surface to be drilled with the face that has the largest opening and, pressed against said surface, to subsequently introduce the drill through the openings and perform the corresponding drilling.
En los casos en los que el orificio de taladrado se practique sobre superficies verticales, el dispositivo se apoyará entonces sobre la superficie a perforar con el cuerpo del prisma orientado hacia el suelo, para no derramar el líquido refrigerante y una vez hecha Ia presión sobre el dispositivo e insertada Ia broca, se girará 180° con el fin de que el líquido refrigerante caiga sobre Ia broca sin derramarse.In cases where the drilling hole is made on vertical surfaces, the device will then rest on the surface to be drilled with the prism body facing the ground, so as not to spill the cooling liquid and once the pressure on the device and inserted the drill bit, it will be rotated 180 ° so that the coolant falls on the drill bit without spilling.
