Abstract

The present invention discloses a tool for surface roughing, in particular for flooring, of the type consisting of a support (1) to be applied to a machine and of a layer made of an abrasive material fixed to such support, where the abrasive member consists of several diamond sectors (5) fitted onto said support (1) and buried into a mass of soft material, especially rubber. This configuration allows obtaining a tool capable of effectively machining the surface, performing an effective abrasive action without having these sectors damage the edges of ceramic or similar tiles. In practice, the mass of soft material where the diamond sectors (5) are buried serves as a protection to prevent them from scratching the edges of the tiles or slabs forming the flooring, but allowing the diamond to scrape the surface quite deeply. <IMAGE>

Description

Herramienta para trabajos de desbaste de superficies, en particular para pavimentación.Tool for roughing works surfaces, in particular for paving.

La presente invención propone una herramienta para el desbaste de superficies, en particular para pavimentación, del tipo formado por un soporte a aplicarse en una máquina y por una capa de material abrasivo fijada en dicho soporte, en la cual el elemento abrasivo está formado por varios sectores diamantados montados en dicho soporte y embebidos en una masa de material blando, en particular a base de goma.The present invention proposes a tool for surface roughing, particularly for paving, of the type formed by a support to be applied in a machine and by a layer of abrasive material fixed on said support, in which the abrasive element is formed by several diamond sectors mounted on said support and embedded in a mass of material soft, particularly rubber based.

Esta configuración permite obtener una herramienta capaz de trabajar de manera eficaz la superficie, desempeñando una acción abrasiva eficaz, pero sin que estos sectores dañen los bordes de losas de cerámica o similares.This configuration allows you to obtain a tool capable of effectively working the surface, performing an effective abrasive action, but without these sectors damage the edges of ceramic slabs or the like.

En esencia, la masa de material blando en la cual se encuentran embebidos los sectores diamantados funciona como protección para evitar que éstos dañen las esquinas de las losas o de las placas que forman la pavimentación, permitiendo de todos modos al diamante raspar la superficie de manera bastante profunda.In essence, the mass of soft material in the which are embedded diamond sectors works as protection to prevent them from damaging the corners of the slabs or of the plates that form the paving, allowing everyone diamond modes scrape the surface quite a bit deep

La invención se refiere al sector del equipo para el acabado de superficies y concierne en particular a los equipos para el acabado de pavimentaciones o similares.The invention relates to the equipment sector for surface finishing and concerns in particular pavement finishing equipment or similar.

Como ya se sabe, una vez colocada la pavimentación es necesario nivelarla y alisarla, para luego completar el acabado con una operación de pulido, cuando se solicite.As you know, once placed the paving is necessary to level and smooth it, and then complete the finish with a polishing operation, when I requested.

Con esta finalidad se utilizan máquinas equipadas con un dispositivo giratorio en el cual se colocan herramientas tipo discos abrasivos o similares y que se ponen en rotación apoyadas sobre el material a elaborar, para llevar a cabo el desbaste, el alisado y el pulido.For this purpose machines are used equipped with a rotating device in which they are placed tools such as abrasive or similar discs that are placed in rotation supported on the material to be made, to carry out roughing, smoothing and polishing.

Generalmente estas máquinas incluyen un marco montado sobre ruedas y un motor eléctrico que acciona un motor de eje esencialmente vertical, en el cual se coloca una placa de soporte y varias herramientas.Generally these machines include a frame mounted on wheels and an electric motor that drives a motor essentially vertical axis, in which a plate of Support and various tools.

Las herramientas están formadas por sectores de material abrasivo, en base al tipo de acabado que se desea obtener.The tools are formed by sectors of abrasive material, based on the type of finish desired obtain.

Como dicho anteriormente, para los trabajos de desbaste, se utilizan sectores abrasivos de grano grueso, capaces de extraer cierta cantidad de material de la pavimentación para nivelarla y alisarla.As said above, for the works of roughing, coarse-grained abrasive sectors are used, capable of extract a certain amount of paving material to level and smooth it.

Estas herramientas pueden ser de superficie continua, formadas por ejemplo por un disco o por un dispositivo de corona circular plano o bien por una serie de sectores montados uno al lado del otro, sobre un soporte generalmente circular.These tools can be surface continuous, formed for example by a disk or by a device flat circular crown or by a series of sectors mounted one side by side, on a generally circular support.

Sin embargo, las herramientas formadas por varios sectores colocados uno al lado del otro algunas veces presentan inconvenientes, ya que si se interviene en una pavimentación formada por losas, placas de piedra o similares, puede suceder que los sectores, que rotando chocan contra las esquinas de las losas que emergen respecto a las demás, puedan fragmentarlas o de todos modos dañarlas.However, the tools formed by several sectors placed side by side sometimes they have drawbacks, since if they intervene in a paving formed by slabs, stone slabs or the like, can happen that the sectors that rotate collide with the corners of the slabs that emerge with respect to the others, can fragment them or anyway damage them.

Este riesgo no existe o es mucho menor con herramientas de superficie continua, como las redondas, sin embargo, éstas ejercen sobre la pavimentación una acción menos eficaz, necesitándose así tiempos de intervención mayores para lograr el mismo resultado.This risk does not exist or is much lower with continuous surface tools, such as round ones, however, these exert a less effective action on paving, needing longer intervention times to achieve the same result.

WO-A-96 26811 describe un elemento abrasivo flexible con forma permanente unidireccional y un método para realizarlo; dicho elemento abrasivo tiene un soporte dotado, por un lado, de un enganche y por el otro lado de una herramienta abrasiva formada por una serie de sectores y por una forma unidireccional hecha de material expandido flexible, que circunda los sectores y se extiende a lo largo de por lo menos parte de su altura. Ninguna capa intermedia de material deformable se encuentra en la herramienta, entre dicho soporte y los sectores.WO-A-96 26811 describes a flexible abrasive element with permanent shape unidirectional and a method to do it; said abrasive element it has a support provided, on the one hand, with a hitch and on the other side of an abrasive tool formed by a series of sectors and by a unidirectional shape made of flexible expanded material, that surrounds the sectors and extends along at least part of its height. No intermediate layer of deformable material is in the tool, between said support and the sectors.

La presente invención proporciona una herramienta para trabajos de desbaste de superficies y pavimentaciones del tipo formado por un soporte a montar en una máquina para acabados, en la que varios sectores formados por gránulos de material abrasivo combinados con un ligante están soldados en un soporte de red o en un soporte agujereado, todo esto encontrándose embebido en una capa de goma vulcanizada, se caracteriza por el hecho de que entre dicho soporte de red o soporte agujereado y dicho soporte a montar en la máquina, se encuentra una capa de material blando, específicamente de goma vulcanizada. La herramienta es capaz de evitar los inconvenientes antes mencionados y está formada por varios sectores diamantados fijados en un soporte flexible y embebidos en una capa de material blando, por ejemplo goma o similares, la cual evita el impacto de los sectores contra los bordes y las esquinas de las losas, que sin embargo permiten, gracias a las características de elasticidad y deformabilidad ejercer una acción de desbaste de la superficie.The present invention provides a tool for surface roughing work and pavements of the type formed by a support to be mounted on a finishing machine, in which several sectors formed by abrasive material granules combined with a binder are soldiers in a net support or in a bored support, all this being embedded in a vulcanized rubber layer, it characterized by the fact that between said network support or support bored and said support to be mounted on the machine, there is a soft material layer, specifically vulcanized rubber. The tool is able to avoid the aforementioned inconveniences and consists of several diamond sectors fixed on a support flexible and embedded in a layer of soft material, for example rubber or similar, which avoids the impact of the sectors against the edges and corners of the slabs, which however allow, thanks to the characteristics of elasticity and deformability exert a surface roughing action.
