Muela de desbaste Grinding wheel
La invenci6n se refiere a una muela de desbaste. The invention refers to a grinding wheel.
Por el documento CH-PS 434 023 se conoce una muela tangencial de esta clase relativamente gruesa, que esta A relatively thick tangential wheel of this kind is known from document CH-PS 434 023, which is
5 compuesta por varias muelas parciales pegadas entre si en toda la superficie, reforzadas con tejido, pudiendo estar previsto un suplemento elastico en la capa de pegamento. Esta clase de muelas de paquete tiene una capacidad de amolado superior a la de una muela compacta realizada de una sola pieza. 5 composed of several partial wheels glued together on the entire surface, reinforced with fabric, an elastic supplement may be provided in the glue layer. This class of package wheels has a grinding capacity greater than that of a compact wheel made in one piece.
Por el documento CH-PS 434 023 se conoce ademas una muela compacta que en sus zonas radiales exteriores presenta sendas zonas exentas de abrasivo, que esta formada por capas intermedias de forma anular que In addition, from document CH-PS 434 023 a compact wheel is known which in its outer radial zones has paths free of abrasive, which is formed by intermediate layers of annular shape which
10 eventualmente se pueden volver a retirar, de modo que se forma un intersticio claro entre las zonas contiguas. Durante el amolado tangencial estas zonas exentas de abrasivo dan lugar a un corte especialmente frio, generando ademas mayor espacio para la viruta, lo cual permite obtener un incremento considerable del rendimiento de amolado, siendo por lo demas igual la composici6n de la muela. 10 can eventually be removed again, so that a clear gap is formed between adjacent areas. During the tangential grinding, these abrasive-free zones give rise to a particularly cold cut, also generating more space for the chip, which allows a considerable increase in the grinding performance to be obtained, the composition of the grinding wheel being the same.
Por el documento EP 1 543 923 A1 se conoce una muela de desbaste realizada como muela compacta, cuyo From EP 1 543 923 A1 a roughing wheel is known as a compact wheel, whose
15 diametro es superior a su espesor, por lo menos en un factor de 10. Esta clase de muelas de desbaste se emplean en amoladoras angulares conducidas a mano, de accionamiento neumatico o electrico. Durante el trabajo de amolado aparecen intensas vibraciones que pueden causar considerables dafos fisicos al sistema de mano-brazo del usuario. Para reducir esta clase de vibraciones estan dispuestas en una zona de trabajo exterior entre las distintas capas, sendas capas de separaci6n de forma anular. Dentro de esta zona de trabajo presenta una 15 diameter is greater than its thickness, at least by a factor of 10. This kind of grinding wheels are used in hand-driven angle grinders, pneumatically or electrically operated. Intense vibrations appear during grinding work that can cause considerable physical damage to the user's hand-arm system. To reduce this kind of vibrations, they are arranged in an outer working area between the different layers, each layer separating them annularly. Within this work zone it presents a
20 estructura compacta. La capa de separaci6n tiene principalmente la funci6n de reducir la amplitud de las vibraciones durante el amolado. 20 compact structure. The separation layer mainly has the function of reducing the amplitude of the vibrations during grinding.
Por el documento US 3, 081,584 A se conoce una muela compacta que esta compuesta por varias capas de grano abrasivo aglutinado con resina sintetica y varias capas de armaduras a base de capas de fibra de vidrio. La muela tiene un buje interior para fijarla en un arbol de accionamiento de una amoladora. From US 3, 081,584 A a compact wheel is known which is composed of several layers of abrasive grain bonded with synthetic resin and several layers of reinforcements based on fiberglass layers. The wheel has an inner bushing to fix it on a drive shaft of a grinder.
25 La invenci6n tiene como objetivo crear una muela de desbaste de vibraciones amortiguadas para el empleo conducido a mano, que tenga una estructura especialmente sencilla y que de este modo resulte especialmente sencilla de fabricar. The aim of the invention is to create a grinding wheel of dampened vibrations for hand-driven use, which has a particularly simple structure and is thus particularly easy to manufacture.
Este objetivo se resuelve conforme a la invenci6n en una muela de desbaste conforme al preambulo de la reivindicaci6n 1 por las caracteristicas de la parte identificativa de la reivindicaci6n 1. This objective is solved according to the invention in a grinding wheel according to the preamble of claim 1 by the characteristics of the identifying part of claim 1.
30 La estructura a base de muelas parciales planas individuales permite realizar una fabricaci6n previa muy sencilla de estas muelas parciales. Puesto que son planas, no existe el riesgo de que sufran una deformaci6n tal como sucede en el caso de las muelas acodadas, por lo que efectivamente asientan entre si del modo mas compacto posible, es decir que en la zona de trabajo exterior que no esta unida, es decir que no esta pegada, asientan entre si casi sin intersticio de aire. Debido a la realizaci6n plana de la muela de desbaste y a la colocaci6n de un buje en ella resulta 30 The structure based on individual flat partial wheels allows a very simple pre-fabrication of these partial wheels. Since they are flat, there is no risk that they will suffer a deformation such as happens in the case of layered wheels, so that they effectively seat each other in the most compact way possible, that is, in the outside work zone that is not together, that is to say that it is not attached, they settle together almost without air gap. Due to the flat realization of the grinding wheel and the placement of a bushing on it, it results
35 especialmente ventajoso prever en el buje una rosca interior mediante la cual resulte posible enroscarla sobre una rosca exterior de un arbol de salida de una amoladora manual. Esto da lugar a que a pesar de la configuraci6n plana, no se requiere ninguna tuerca de fijaci6n sobre el arbol de salida de la amoladora que sobresalga de la muela de desbaste, de modo que resulta posible tambien el empleo plano o casi plano de la muela de desbaste conforme a la invenci6n. Esta realizaci6n del buje puede emplearse naturalmente tambien en muelas planas que no presenten la 35 It is especially advantageous to provide an internal thread in the bushing by means of which it is possible to screw it onto an external thread of an output shaft of a hand grinder. This results in that despite the flat configuration, no fixing nut is required on the grinder shaft that protrudes from the grinding wheel, so that the flat or almost flat use of the wheel is also possible of roughing according to the invention. This embodiment of the hub can naturally also be used on flat wheels that do not have the
40 estructura conforme a la invenci6n. 40 structure according to the invention.
Unas realizaciones ventajosas se deducen de las reivindicaciones subordinadas. Otras caracteristicas, ventajas y detalles de la invenci6n se deducen de la siguiente descripci6n de un ejemplo de realizaci6n, sirviendose del dibujo. En este muestran: Advantageous embodiments are deduced from the dependent claims. Other features, advantages and details of the invention are deduced from the following description of an embodiment example, using the drawing. In this show:

50 la fig. 5 una muela de desbaste conforme a la invenci6n montada sobre el arbol de salida de una amoladora manual, en una vista lateral. 50 fig. 5 a grinding wheel according to the invention mounted on the output shaft of a hand grinder, in a side view.
Tal como se puede ver en las fig. 1 y 5, las muelas de desbaste 1 se utilizan en amoladoras manuales 2, concretamente en las llamadas amoladoras angulares. La muela 1 presenta para esto un orificio central 3 en el que As can be seen in fig. 1 and 5, the grinding wheels 1 are used in manual grinders 2, specifically in the so-called angle grinders. The wheel 1 has for this a central hole 3 in which
va colocado un buje 4. Este buje 4 tiene una rosca interior 5 mediante la cual se enrosca la muela 1 sobre un arbol de salida � de la amoladora 2, dotado de una rosca exterior 6. a bushing 4 is placed. This bushing 4 has an internal thread 5 by means of which the wheel 1 is screwed onto an output shaft � of the grinder 2, provided with an external thread 6.
La estructura basica de la muela 1 consta de varias muelas parciales delgadas 8, concretamente entre dos y diez, con un diametro exterior D. Cada muela parcial 8 presenta en sus dos caras exteriores sendas armaduras 9, 10, donde entre las dos armaduras 9, 10 esta dispuesto el grano abrasivo 11 ligado con aglutinantes, por lo general de resina fen6lica. Las armaduras 9, 10 son de un tejido impregnado con el aglutinante del grano abrasivo 11, por lo general un tejido de vidrio. Estas muelas parciales 8 estan endurecidas. Las muelas parciales 8 no presentan en sus caras exteriores, es decir en las superficies descubiertas de las armaduras 9, 10, ninguna etiqueta ni capa de papel The basic structure of the wheel 1 consists of several thin partial wheels 8, specifically between two and ten, with an outer diameter D. Each partial wheel 8 has two armatures on its two outer faces, where between the two armors 9, 10 the abrasive grain 11 bound with binders, usually of phenolic resin, is arranged. The reinforcements 9, 10 are made of a fabric impregnated with the binder of the abrasive grain 11, usually a glass fabric. These partial wheels 8 are hardened. The partial wheels 8 do not have on their outer faces, that is on the bare surfaces of the armor 9, 10, no label or paper layer
o similar, careciendo por lo tanto de revestimiento. or similar, therefore lacking coating.
Para fabricar una muela de desbaste 1 se apilan unas sobre otras varias muelas parciales 8 de forma plana, y en una zona de forma anular alrededor del orificio central 3 se aplica cada vez una capa de pegamento 12, por lo general un dur6mero. Esta capa de pegamento 12, de un diametro d, es en cada caso tan delgada que al comprimir el paquete compuesto por varias muelas parciales 8 para formar una muela de desbaste 1, el pegamento queda absorbido en la rugosidad superficial de las muelas parciales 8 adosadas entre si. La consecuencia de esto es que las muelas parciales que estan firmemente unidas entre si en la zona de la capa de pegamento 12 de diametro d, y que fuera de la respectiva capa de pegamento 12 no estan unidas entre si pero quedan estrechamente adosadas. A este respecto, "estrechamente adosadas" no significa que las muelas 1 contiguas presenten aqui una separaci6n de exactamente 0, sino de que entre dos muelas parciales 8 contiguas no existe practicamente un intersticio de aire relevante. Para el espesor a de una muela 1 compuesta por n muelas parciales 8 de un espesor b, se aplica por lo tanto: a ' n x b. Para el espesor b de las muelas parciales 8 rige: 0,8 mm � b � 1, 4 mm. Para la relaci6n entre el diametro d de la capa de pegamento 12 y el diametro exterior D de la muela 1 rige: 0,2 � dID � 0,65. Para el diametro exterior D rige: 10 mm � D � 300 mm. La zona en la que las muelas parciales 8 contiguas no estan unidas entre si forma la zona de trabajo 13 de la muela 1. To make a grinding wheel 1, several partial wheels 8 are stacked on top of one another, and in a ring-shaped area around the central hole 3 a layer of glue 12 is applied each time, usually a durometer. This layer of glue 12, of a diameter d, is in each case so thin that by compressing the package composed of several partial wheels 8 to form a grinding wheel 1, the glue is absorbed in the surface roughness of the partial wheels 8 attached each. The consequence of this is that the partial wheels that are firmly joined together in the area of the glue layer 12 of diameter d, and that outside the respective glue layer 12 are not joined together but are closely attached. In this respect, "closely attached" does not mean that the adjacent molars 1 here have a separation of exactly 0, but that between two adjacent partial molars 8 there is practically no relevant air gap. For the thickness a of a wheel 1 composed of n partial wheels 8 of a thickness b, therefore: a 'n x b. For thickness b of partial wheels 8, it applies: 0.8 mm � b � 1, 4 mm. For the relationship between the diameter d of the glue layer 12 and the outer diameter D of the wheel 1, it applies: 0.2 d dID � 0.65. For the outside diameter D applies: 10 mm � D � 300 mm. The area in which the adjacent partial wheels 8 are not joined together form the work zone 13 of the wheel 1.
El buje 4 atraviesa solo ligeramente de lado a lado el orificio central 3 de la muela 1 por uno de los lados, concretamente por el lado alejado de la amoladora 2, con un borde 14 rebordeado, de tal modo que aunque la muela de desbaste 1 no este acodada sino realizada totalmente plana, se pueda emplear en posici6n oblicua como muela de desgaste 1, es decir en la forma descrita inicialmente y representada en la fig. 1. Pero tambien cabe la posibilidad de realizar un esmerilado plano en el que la muela de desbaste 1 se aplica sobre una pieza 16 con su cara frontal 15 correspondiente al borde 14 del buje, en forma plana o sensiblemente plana. Si la muela de desbaste 1 se emplea en posici6n oblicua segun la representaci6n de la fig. 1, se hace esto con un angulo a entre un eje 1� de la muela 1 y por lo tanto tambien del arbol de salida de la amoladora 2, respecto a una perpendicular 18 a la superficie 19 de la pieza 16 que se trata de amolar. Para el angulo a rige: 200 � a � 600. En cambio si se realiza un amolado plano en la forma citada entonces para el angulo a rige: a ' 00. The bushing 4 crosses only slightly from side to side the central hole 3 of the wheel 1 on one of the sides, specifically on the side away from the grinder 2, with a flanged edge 14, so that although the grinding wheel 1 not bent, but made completely flat, it can be used obliquely as a grinding wheel 1, that is to say in the manner initially described and represented in fig. 1. But it is also possible to make a flat grinding in which the grinding wheel 1 is applied on a piece 16 with its front face 15 corresponding to the edge 14 of the bushing, in a flat or substantially flat shape. If the grinding wheel 1 is used in an oblique position according to the representation of fig. 1, this is done with an angle to between an axis 1� of the wheel 1 and therefore also of the grinder shaft 2, with respect to a perpendicular 18 to the surface 19 of the piece 16 which is to be ground . For the angle to rule: 200 � to � 600. On the other hand, if a flat grinding is performed in the manner cited then for the angle to rule: a '00.
