Refuerzo para tambor de máquina lavadora.Reinforcement for drum of washing machine.
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un procedimiento para reforzar y a un refuerzo para tambor de máquina lavadora, cuya finalidad es conseguir una mayor resistencia mecánica de la banda del tambor de una lavadora que está sometida a esfuerzos y solicitaciones mecánicas durante el giro de éste cuando las revoluciones son elevadas.The present invention, as expressed in the set forth in this specification, refers to a reinforcement procedure and reinforcement for machine drum washing machine, whose purpose is to achieve greater resistance Mechanical drum band of a washing machine that is subjected to mechanical stresses and stresses during its turn when Revolutions are high.
Como es sabido, el tambor de las lavadoras y concretamente la banda cilíndrica del mismo, está sometida a solicitaciones mecánicas cuyos efectos se ven aumentados cuanto mayor es el número de revoluciones por minuto del tambor. Es evidente que durante la fase de centrifugado, las revoluciones son muy elevadas y se llega a producir un abombamiento de la banda debido al aumento de la fuerza centrifuga producido por las altas revoluciones y la irregular disposición de la ropa en el interior del tambor.As is known, the drum of washing machines and specifically the cylindrical band thereof, is subjected to mechanical solicitations whose effects are increased when The greater the number of revolutions per minute of the drum. Is Obviously, during the spin phase, the revolutions are very high and there is a swelling of the band due to the increase in centrifugal force produced by high revolutions and the irregular arrangement of clothes inside of the drum
En ocasiones, se llega a producir la rotura o desgarro de la banda constitutiva de la superficie lateral del tambor en su unión con las paredes constitutivas del fondo y frontal del propio tambor que suele ser unión de soldadura o simplemente por agrafado (doblado de ambas chapas), con los consiguientes problemas de inutilización de éste, siendo necesaria su sustitución o su reparación conveniente, de manera que en cualquier caso los inconvenientes y costos para el usuario son evidentes.Occasionally, breakage occurs or tear of the constitutive band of the lateral surface of the drum at its junction with the bottom walls and front of the drum itself which is usually welding union or simply by agrafado (folded of both plates), with the consequent problems of uselessness of this one, being necessary replacement or convenient repair, so that in In any case, the inconvenience and costs for the user are obvious.
Es decir, actualmente y debido a la constitución y diseño de los tambores de lavadoras, debido a la fuerza centrífuga que se produce al girar el tambor a gran velocidad, se produce un combado o abombamiento del mismo, lo que provoca que el esfuerzo a soportar en los extremos sea mayor y por lo tanto ésta sea otra de las causas que provocan el desgarro del tambor. Para evitarlo, los fabricantes usan chapas de más espesor y refuerzan los pliegues de los agrafados.That is, currently and due to the constitution and design of washing machine drums, due to the force centrifuge that occurs when the drum is rotated at high speed, it produces a bending or bulging thereof, which causes the effort to endure at the extremes is greater and therefore this be another cause that causes the tearing of the drum. For avoid it, manufacturers use thicker sheets and reinforce the folds of the agrafados.
La invención tiene por objeto un refuerzo para tambor de máquina lavadora en las que dicho tambor de configuración cilíndrica gira en torno a un eje en el interior de una cuba de lavado donde se introduce agua para el lavado de la ropa y que comprende una banda lateral con unos orificios para la entrada de agua en el interior del tambor, la cual está unida a un fondo de tambor y a un frente de tambor, y que presenta al menos una cinta a modo de fleje que abraza al tambor en su perímetro alrededor de la banda para evitar la deformación de esta.The invention aims at a reinforcement for washing machine drum in which said configuration drum cylindrical revolves around an axis inside a tank of washing where water is introduced for washing clothes and that it comprises a side band with holes for the entrance of water inside the drum, which is attached to a bottom of drum and to a drum front, and presenting at least one tape to strapping mode that hugs the drum at its perimeter around the band to prevent deformation of this.
Las cintas actúan de cinturón que mantiene el diámetro del tambor en los momentos de más solicitación de esfuerzos, como cuando aumentan las revoluciones de centrifugado y la carga del tambor está descentrada evitando la deformación por abombamiento que se llega a originar en la misma y que produce la clásica rotura o desgarro en su unión por agrafado con las paredes verticales del propio tambor.The belts act as a belt that keeps the drum diameter at times of most solicitation of efforts, such as when spin speeds increase and The drum load is off center avoiding deformation by bulge that comes to originate in it and that produces the classic breakage or tear at its junction by agrafado with the walls Vertical of the drum itself.
También es preferible que las cintas estén fijadas a la banda para que no haya movimientos relativos de las cintas en al menos dirección del eje del tambor y estas no se desplacen al extremo del tambor donde la deformación es menor y por lo tanto su efecto se vería disminuido.It is also preferable that the tapes are fixed to the band so that there are no relative movements of the tapes in at least direction of the drum shaft and these are not move to the end of the drum where the deformation is less and by therefore its effect would be diminished.
El refuerzo de la invención entonces es al menos una cinta metálica de ancho mucho menor que el de la banda del tambor que se aplica anularmente sobre la superficie de la banda y sus extremos son unidos mecánicamente, por ejemplo por soldadura o remachados ya que por ejemplo el acero puede resistir esas solicitaciones mecánicas.The reinforcement of the invention is then at least a metal tape of width much smaller than that of the band of the drum that is applied annularly on the surface of the band and its ends are mechanically joined, for example by welding or riveted because for example steel can resist those mechanical solicitations
Para el cierre de la cinta, se prevé que ambos extremos terminen en al menos un doblez a modo de gancho para el cierre de la cinta, para que se puedan unir mecánicamente. Y que dichos dobleces formen un ángulo distinto de 90° con la línea longitudinal de la cinta engarzando entre si de forma complementaria, lo que hace que mientras se deslizan los dobleces se consiga el tensado de la cinta sobre la banda. Una vez encajados los dobleces de la cinta se prevé un medio de retención para evitar su separación.For the closure of the tape, it is expected that both ends end in at least one fold as a hook for the tape closure, so that they can be mechanically joined. And that said folds form an angle other than 90 ° with the line length of the tape crimping each other so complementary, which makes the folds slide while get tape tension on the band. Once fitted the folds of the tape is provided a means of retention to avoid their separation
En otra forma de unión de los extremos de la cinta, los dobleces engarzan con una abrazadera que la cierra. Así, la abrazadera puede llevar la carga de la tensión y aumentarla con respecto a la realización anterior. La abrazadera puede tener forma laminar trapezoidal con al menos una lengüeta que fija su posición respecto a la cinta y esta no se desmonta por el uso normal del tambor.In another way of joining the ends of the tape, the folds crimp with a clamp that closes it. So, the clamp can carry the tension load and increase it with regarding the previous embodiment. The clamp can be shaped trapezoidal sheet with at least one tongue that fixes its position with respect to the tape and this is not disassembled by the normal use of the drum.
Y también la cinta es de uso en tambores donde la banda del tambor presenta al menos un pliegue longitudinal en dirección al interior del tambor determinando un rompiente aunque estos separen la cinta de la superficie de la banda, ya que los rompientes no son de gran tamaño.And also the tape is used in drums where the drum band has at least one longitudinal fold in direction inside the drum determining a breaker although these separate the tape from the surface of the band, since the Breakers are not large.
La cinta presenta al menos un pliegue transversal para incrementar la tensión de la cinta que se adapta sobre las correspondientes deformaciones que determinan los rompientes longitudinales con los que va dotada la banda del propio tambor.The tape has at least one fold transverse to increase the tension of the tape that adapts on the corresponding deformations that determine the longitudinal breakers with which the band itself is endowed drum.
La cinta metálica se aplica sobre una zona intermedia de la superficie lateral o banda del tambor ya que es el punto que más esfuerzos tiene que soportar.The metal tape is applied over an area intermediate of the lateral surface or drum band since it is the point that more efforts have to endure.
Y la invención tiene también por objeto el procedimiento para reforzar la banda de un tambor de lavadora como el citado anteriormente en el que los pliegues transversales de la cinta son realizados por una herramienta una vez cerrada dicha cinta sobre la banda, ya que así se aumenta la tensión que tiene la banda tras su montaje y no se destensa fácilmente.And the invention also aims at procedure to reinforce the band of a washing machine drum as the aforementioned in which the transverse folds of the tape are made by a tool once said tape on the band, since this increases the tension of the band after assembly and does not easily release.
La cinta metálica que constituirá el refuerzo para la banda del tambor, es aplicada en el propio proceso de fabricación de éste, es decir en la línea de fabricación correspondiente, cinta que se monta inicialmente de manera pretensionada, es decir, sin carga, siendo después tensionada hasta una presión requerida mediante un útil apropiado con tres pistones, formando pliegues en dicha cinta metálica de refuerzo, para adaptarse a los rompientes longitudinales con que normalmente van dotados los tambores de las lavadoras. Esos pliegues que se forman sobre los rompientes de la banda del tambor, determinan un efecto muelle en la propia cinta metálica.The metal tape that will constitute the reinforcement for the drum band, it is applied in the process of manufacturing of this one, that is to say in the manufacturing line corresponding, tape that is initially mounted so pretensioned, that is, without load, being then stressed until a pressure required by an appropriate tool with three pistons, forming folds in said reinforcing metal tape, for adapt to the longitudinal breakers with which they normally go gifted the drums of the washing machines. Those folds that form on the drum band breakers, determine an effect spring on the metal tape itself.
La herramienta accede a la cinta por el hueco que deja el rompiente una vez que está montada sobre la banda. Puede tener forma de sándwich atrapando entre medio a la cinta y deformándola por presión.The tool accesses the tape through the hole that leaves the breaker once it is mounted on the band. It can be shaped like a sandwich between the tape and deforming it by pressure.
El refuerzo que constituye dicha cinta supone una solución fácilmente industrializable, bajo coste y aplicable a todo tipo de bandas de tambor, ofreciendo una mejora mecánica considerable además de que el efecto muelle que determina la cinta hace que no se afloje durante la vida útil del tambor, es decir, de la lavadora.The reinforcement that constitutes said tape implies an easily industrializable solution, low cost and applicable to All kinds of drum bands, offering a mechanical improvement considerable in addition to the spring effect that determines the tape it does not loosen during the life of the drum, that is, of the washing-machine.
En definitiva, la cinta de refuerzo de la invención evita que la banda del tambor se abombe con el aumento de la fuerza centrífuga producida por las distintas cargas y revoluciones, suponiendo una mejora mecánica considerable al actual sistema de fabricación de tambores de lavadoras.In short, the reinforcement tape of the invention prevents the drum band from bulging with increasing the centrifugal force produced by the different loads and revolutions, assuming a considerable mechanical improvement to the current washer drum manufacturing system.
Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características del invento, se acompaña a la presente memoria descriptiva un juego de dibujos basándose en los cuales se comprenderán más fácilmente las innovaciones y ventajas del refuerzo de la banda de un tambor de lavadora realizado de acuerdo con el objeto de la invención.To complement the description that then it will be done and in order to help a better understanding of the features of the invention, accompanies the present a set of drawings based on the which innovations and advantages will be more easily understood of the reinforcement of the band of a washing machine drum made of according to the object of the invention.

Como se puede ver en las figuras referidas, el tambor 1 de una lavadora, como es convencional, está afectado de una pluralidad de oficios 2 de manera tal que la superficie lateral afectada de esos orificios 2 se denomina "banda" del propio tambor, la cual queda unida a las paredes verticales 3 y 4 constitutivas del frontal y fondo, respectivamente, del propio tambor, de manera que en el frontal 3 es donde está realizada la boca de carga mientras que de la pared de fondo 4 es de donde emerge el correspondiente eje de giro 5 del propio tambor 1.As you can see in the referred figures, the drum 1 of a washing machine, as is conventional, is affected by a plurality of trades 2 such that the lateral surface affected of those holes 2 is called "band" of the own drum, which is attached to vertical walls 3 and 4 constitutive of the front and bottom, respectively, of the own drum, so that the front 3 is where the loading mouth while the back wall 4 is where the corresponding axis of rotation 5 of the drum 1 itself emerges.
Como se ve en la figura 1, como consecuencia de las elevadas revoluciones a que se ven sometidos actualmente los tambores, se produce un abombamiento 6 de la banda constitutiva de la superficie lateral del tambor 1, cuyo abombamiento producirá la rotura o desgarro en los puntos de unión por agrafado 7 entre esa banda abombada 6 del tambor y las paredes verticales 3 y 4 del mismo.As seen in Figure 1, as a result of the high revolutions to which the drums, a bulge 6 of the constitutive band of the lateral surface of the drum 1, whose bulging will produce the breakage or tear at junction points by grading 7 between that domed drum band 6 and vertical walls 3 and 4 of the same.
Pues bien, para evitar esa formación del abombamiento 6 de la banda del tambor 1, se ha previsto una cinta metálica 8 que se aplica anularmente sobre la banda del tambor 1 y en correspondencia con aproximadamente su longitud intermedia, cuya cinta 8 se aplica inicialmente sin carga y en ambos extremos 12, 13 se doblan terminando en dobleces 14, 15 a modo de gancho y entre ellas, se engarza una abrazadera 16 que presenta dobleces que encajan con las de los extremos de la cinta cerrando esta.Well, to avoid that formation of bulging 6 of the drum band 1, a tape is provided metal 8 which is applied annularly on the drum band 1 and in correspondence with approximately its intermediate length, whose tape 8 is initially applied without load and at both ends 12, 13 they are folded ending in folds 14, 15 as a hook and between they clamp a clamp 16 that presents folds that fit with the ends of the tape closing this.
Como se observa en la figura 5, la línea de unión de los extremos de la cinta y la línea longitudinal de la cinta forman un ángulo A y la abrazadera 16 tiene forma laminar trapezoidal para que al engarzarla se tense la cinta y ejerza una presión a la banda del tambor. La abrazadera comprende lengüetas 17, 18 que fijan su posición respecto a la cinta 8 y no permiten que se desmonte por los movimientos del tambor.As seen in Figure 5, the line of union of the ends of the tape and the longitudinal line of the tape forms an angle A and the clamp 16 has a laminar shape trapezoidal so that when crimping it the tape is tensioned and exerts a pressure to the drum band. The clamp comprises tabs 17, 18 that fix their position with respect to the tape 8 and do not allow disassemble by drum movements.
En otra realización, como se ve en las figuras 4 a 6 los extremos de la cinta 12, 13 terminan en dobleces 14', 15' que engarzan entre si de forma complementaria sin necesidad de abrazadera. Una vez engarzados, unas lengüetas 19 en uno de los extremos 12 o 13 se doblan haciendo de medio de retención de los extremos de la cinta para que no se separen.In another embodiment, as seen in figures 4 at 6 the ends of the tape 12, 13 end in folds 14 ', 15' that engage each other in a complementary way without needing clamp. Once crimped, 19 tabs on one of the ends 12 or 13 are folded making retention means of the tape ends so that they do not separate.
Luego se lleva a cabo una deformación o pliegues 9 en correspondencia con los rompientes 10 con que están dotados normalmente los tambores 1 de las lavadoras. Se mecanizan esos pliegues 9 en su adaptación sobre los rompientes 10, mediante los pistones de un útil apropiado 11 que se dispone tal y como se representa claramente en la figura 3, viéndose en la figura 2 las deformaciones o pliegues 9 de la cinta de refuerzo 8, determinando éstas últimas un efecto muelle en la propia cinta de refuerzo 8, que evita que se afloje durante la vida útil de la lavadora, en este caso del tambor.Then a deformation or folds are carried out 9 in correspondence with the breakers 10 with which they are endowed normally the drums 1 of the washing machines. Those are mechanized folds 9 in their adaptation on the breakers 10, by means of the pistons of an appropriate tool 11 that is arranged as clearly depicted in figure 3, looking in figure 2 the deformations or folds 9 of the reinforcement tape 8, determining the latter a spring effect on the reinforcement tape 8 itself, which prevents loosening during the life of the washer, in This drum case.
