Abstract

The invention relates to a rolling rack of the type that comprises a toothed rolling surface. The invention is characterised in that one of the ends of the toothed surface comprises a strip of material having a coefficient of friction that is greater than that of the material forming the toothing of the rolling surface, said strip forming a non-zero oblique angle in relation to the teeth of the toothed surface. In this way, the strip extends through a certain number of teeth of the toothed surface, the height of said strip being at least equal to that of the teeth through which it extends.

Description

CREMALLERA DE LAMINAR LAMINAR ZIPPER
DESCRIPCIÓNDESCRIPTION
La presente invención hace referencia a una cremallera de laminar, así como a una máquina de laminación de ejes que comprende la misma.The present invention refers to a laminar rack, as well as a shaft rolling machine comprising it.
Una cremallera de laminar es una herramienta, habitualmente de forma general paralelepipédica, que presenta una cara de laminación dentada. Las cremalleras de laminar se utilizan en la fabricación de ejes dentados, estriados o roscados. En una máquina de laminación de ejes se colocan, de manera habitual, dos de estas cremalleras separadas una distancia conocida como abertura de máquina y se desplazan longitudinalmente en sentidos opuestos, de manera tal que cada una hace contacto con el eje a laminar en lados opuestos de la superficie lateral del eje, comprimiéndolo. El eje gira por el contacto de las cremalleras, de manera tal que al pasar las cremalleras en su movimiento tangente al eje a laminar, se genera un dentado o estriado en el eje.A laminar rack is a tool, usually generally parallelepipedic, that has a serrated rolling face. Laminar zippers are used in the manufacture of toothed, grooved or threaded shafts. In a shaft rolling machine, two of these separate zippers are placed in a usual manner a distance known as a machine opening and move longitudinally in opposite directions, so that each one makes contact with the axis to be laminated on opposite sides of the lateral surface of the shaft, compressing it. The axis rotates through the contact of the zippers, so that when the zippers pass in tangent movement to the axis to be rolled, a toothed or grooved is generated in the axis.
De manera habitual, las caras de laminación dentadas de las cremalleras de laminar presentan tres zonas diferenciadas. La primera zona o zona de entrada, que es la destinada a realizar el primer contacto con el eje a laminar. Habitualmente dicha zona se distingue por presentar una altura de los dientes de la cremallera que aumenta progresivamente, de manera tal que, en funcionamiento, esta zona realiza una compresión progresiva del eje a laminar, con una realización igualmente progresiva del estriado o dentado del eje. A continuación se sitúa la zona de acabado, cuya función es la de calibrar el estriado o dentado del eje, para que los dientes o estrías presenten la forma y dimensiones deseadas. Los dientes de la zona de acabado presentan por ello habitualmente la misma forma y dimensión. Por fin, a continuación de la zona de acabado se sitúa la zona de salida o zona de descompresión, en la que los dientes tienen una pérdida de altura progresiva. La función de la zona de salida consiste en que la pieza disminuya su contacto con la cremallera de forma gradual.Typically, the serrated lamination faces of the laminar zippers have three distinct zones. The first zone or entrance zone, which is the one destined to make the first contact with the axis to be laminated. Usually said area is distinguished by having a height of the rack teeth that increases progressively, so that, in operation, this area performs a progressive compression of the axis to be laminated, with an equally progressive embodiment of the spline or toothed axis. Next is the finishing zone, whose function is to calibrate the spline or toothed shaft, to that the teeth or stretch marks have the desired shape and dimensions. The teeth of the finishing zone therefore usually have the same shape and dimension. Finally, after the finishing zone, the exit zone or decompression zone is located, in which the teeth have a progressive loss of height. The function of the exit zone is that the piece decreases its contact with the rack gradually.
Para obtener una correcta formación de los dientes en el eje es necesario que la velocidad lineal de las cremalleras sea idéntica a la velocidad del eje en la superficie tangencial en la zona de contacto. Dado que la transmisión del movimiento entre cremalleras y eje a laminar se realizan por contacto de los dientes de las cremalleras con la superficie lateral de la pieza, resulta extremadamente importante evitar que se produzcan deslizamientos en los momentos iniciales de contacto entre las cremalleras y el eje a laminar.In order to obtain a correct formation of the teeth on the shaft it is necessary that the linear speed of the zippers be identical to the speed of the axis on the tangential surface in the contact area. Since the transmission of the movement between zippers and shaft to be rolled is made by contact of the teeth of the zippers with the lateral surface of the piece, it is extremely important to avoid slippage at the initial moments of contact between the zippers and the shaft to laminate
Para evitar el deslizamiento entre las cremalleras y el eje a laminar, es conocida la realización de un arenado en la superficie dentada del inicio de la zona de entrada de la cremallera. Asimismo, de acuerdo con la técnica conocida, es necesario que los primeros dientes en la citada zona de entrada presenten una geometría de diente plana, con el fin de asegurar un mejor contacto y capacidad de transmisión de movimiento. Ambas medidas conocidas presentan el problema de que el laminado del eje es excesivamente brusco, lo que resulta en una elevada fatiga de las herramientas y una menor vida de las mismas. Con objeto de solucionar los problemas antes citados, la presente invención consiste en una cremallera de laminar, del tipo que comprende una cara de laminación dentada. La cremallera objeto de la presente invención se caracteriza porque en uno de los extremos de su cara dentada, también denominada zona de entrada, presenta, una tira de un material con un coeficiente de rozamiento superior al del material del dentado de la cara de laminación, formando dicha tira un ángulo oblicuo, distinto de cero, con respecto a los dientes de la cara dentada, de manera tal que la tira atraviesa un cierto número de dientes de dicha cara, presentando dicha tira, al menos, la misma altura que los dientes que atraviesa.In order to avoid the sliding between the zippers and the shaft to be laminated, it is known to make a sandblasting on the toothed surface of the start of the entrance zone of the rack. Likewise, according to the known technique, it is necessary that the first teeth in said entrance area have a flat tooth geometry, in order to ensure a better contact and movement transmission capacity. Both known measures present the problem that the shaft rolling is excessively abrupt, resulting in high tool fatigue and reduced life of the tools. In order to solve the problems before cited, the present invention consists of a laminar rack, of the type comprising a serrated rolling face. The zipper object of the present invention is characterized in that at one of the ends of its toothed face, also called the entrance area, it has a strip of a material with a coefficient of friction greater than that of the toothed material of the rolling face, said strip forming an oblique angle, other than zero, with respect to the teeth of the toothed face, such that the strip passes through a certain number of teeth of said face, said strip having at least the same height as the teeth that goes through.
Preferentemente, la tira se realizará en un material elástico. Más preferente, dicha tira se realizará en un material de alto coeficiente de rozamiento, como por ejemplo una goma.Preferably, the strip will be made of an elastic material. More preferably, said strip will be made of a high friction coefficient material, such as a rubber.
De acuerdo con la presente invención, la zona de mayor coeficiente de rozamiento, al entrar en contacto con un eje a laminar, evita el deslizamiento entre el eje a laminar y la cremallera o cremalleras, asegurándose de esta manera la correcta sincronización de los movimientos rotatorio en el eje a laminar y lineal de las cremalleras. La inclinación de la tira con respecto a los dientes evita la generación de zonas sin laminar. En las diferentes realizaciones, se elegirá un ángulo entre la tira y los dientes de manera tal que, en funcionamiento, se asegure que en el momento de pérdida de contacto entre la tira y el eje a laminar, la profundidad de las estrías realizadas en el eje asegura que no se producirán deslizamientos entre la cremallera y el eje en laminación. Por lo tanto, dicho ángulo se determinará en función de los diferentes parámetros de funcionamiento de cada aplicación en particular, tales como materiales, anchura a laminar, presión ejercida, etcétera.In accordance with the present invention, the area with the highest coefficient of friction, when coming into contact with a shaft to be rolled, prevents sliding between the shaft to be laminated and the rack or zippers, thus ensuring the correct synchronization of the rotational movements in the laminar and linear axis of the zippers. The inclination of the strip with respect to the teeth prevents the generation of unlaminated areas. In the different embodiments, an angle between the strip and the teeth will be chosen such that, in operation, it is ensured that at the time of loss of contact between the strip and the shaft to be laminated, the depth of the grooves made in the shaft ensures that there will be no slippage between the rack and the rolling shaft. Therefore, said angle It will be determined based on the different operating parameters of each particular application, such as materials, width to be laminated, pressure exerted, and so on.
También de manera preferente, con el fin de asegurar el contacto entre el eje a laminar y la tira, ésta última sobresaldrá por encima de los dientes que atraviesa.Also preferably, in order to ensure contact between the shaft to be laminated and the strip, the latter will protrude above the teeth it passes through.
En otra realización preferente, la diferencia de altura de la tira con respecto a los dientes aumentará progresivamente desde el punto más extremo de la cara dentada hasta alcanzar un máximo, para disminuir progresivamente hasta el final de la tira.In another preferred embodiment, the difference in height of the strip with respect to the teeth will increase progressively from the most extreme point of the serrated face to a maximum, to decrease progressively until the end of the strip.
La presente invención presenta, además, la ventaja de permitir la realización de geometrías agudas en los dientes de la zona de entrada sin pérdida de las propiedades antideslizamiento de la cremallera de laminar, lo que no resultaba posible con las cremalleras de laminar anteriormente conocidas. Mediante la presente invención es posible obtener una laminación de los dientes de la cremallera en el eje mucho más suave, y en consecuencia disminuir aún más la fatiga para las herramientas.The present invention also has the advantage of allowing sharp geometries to be made in the teeth of the entrance area without loss of the anti-slip properties of the laminar rack, which was not possible with the previously known laminar racks. By means of the present invention it is possible to obtain a lamination of the teeth of the rack on the shaft much smoother, and consequently reduce even more fatigue for the tools.
La presente invención también comprende una máquina de laminar ejes que se caracteriza porque comprende al menos una cremallera según la presente invención.The present invention also comprises an axis laminating machine characterized in that it comprises at least one rack according to the present invention.

Las figuras 1 a 3 muestran un ejemplo de realización de una cremallera de laminar según la presente invención. En el ejemplo mostrado, la cremallera de laminar -1- presenta un cuerpo de forma general paralelepipédica -2-, que presenta en su cara superior -3- una serie de dientes, tal como los que se ha indicado en las diferentes figuras con el numeral -4-. La cremallera del ejemplo muestra una tira -5- en uno de los extremos de la cremallera. La tira forma un ángulo oblicuo, distinto de cero con los dientes -4- que atraviesa. El extremo de la superficie dentada -3- en el que se sitúa la tira -5- quedará destinado, en uso, a realizar el primer contacto con el eje a laminar (zona de entrada) . De acuerdo con las técnicas conocidas, los dientes -4- de la zona podrán presentar una altura creciente desde el citado extremo. Sin embargo, a diferencia de las cremalleras de laminar anteriormente conocidas, dichos dientes -4- de la zona de entrada podrán presentar una geometría aguda, lo que ha sido representado de manera esquemática en las figuras.Figures 1 to 3 show an exemplary embodiment of a laminar rack according to the present invention. In the example shown, the laminar rack -1- has a generally parallelepipedic body -2-, which has on its upper face -3- a series of teeth, such as those indicated in the different figures with the numeral -4-. The zipper in the example shows a strip -5- at one end of the zipper. The strip forms an oblique angle, nonzero with the teeth -4- that it crosses. The end of the toothed surface -3- on which the strip -5- is located will be destined, in use, to make the first contact with the axis to be laminated (entrance area). According to known techniques, the teeth -4- of the area may have an increasing height from said end. However, unlike the zippers of previously known laminar, said teeth -4- of the entrance area may have an acute geometry, which has been schematically represented in the figures.
La tira -5- será de un material con un coeficiente de rozamiento superior al de los dientes -A- de la cara dentada -3-, por ejemplo, una goma, que es un material preferente por su elasticidad y su alto coeficiente de rozamiento. Por otro lado, en el ejemplo mostrado, tal como se observa en la figura 2, la tira -5- presenta una altura mayor que los dientes -4- que atraviesa, aumentando la diferencia de altura entre la tira -5- y los dientes -4- a partir del extremo de la cara dentada -3-, hasta alcanzar un máximo que en el caso del ejemplo se produce en el segundo diente, y luego va disminuyendo progresivamente hasta casi hacerse nula al final de la tira -5-.The strip -5- will be of a material with a coefficient of friction greater than that of the teeth -A- of the toothed face -3-, for example, a rubber, which is a preferred material for its elasticity and its high coefficient of friction . On the other hand, in the example shown, as seen in Figure 2, the strip -5- has a height greater than the teeth -4- it crosses, increasing the difference in height between the strip -5- and the teeth -4- from the end of the toothed face -3-, until reaching a maximum that in the case of the example occurs in the second tooth, and then gradually decreases until it becomes almost null at the end of the strip -5-.
En las figuras 4 a 6 se muestra, de manera esquemática, el proceso de realización de un eje dentado en una máquina de laminar ejes que comprende al menos una cremallera según la presente invención, más en concreto, dos cremalleras -1-, -1'- según la presente invención. En la cremallera inferior -1- se indican los elementos que son similares a aquellos mostrados en el ejemplo de las figuras 1 a 3 con idénticos numerales -2-, -3-, -4-, -5-, mientras que en la cremallera superior -1 '- éstos se indican también con idénticos numerales, seguidos de una prima -2'-, -3'-, -4'-, -5'-.Figures 4 to 6 show, in a schematic way, the process of realization of a toothed shaft in an axis laminating machine comprising at least one rack according to the present invention, more specifically, two zippers -1-, -1 '- according to the present invention. In the lower zipper -1- the elements that are similar to those shown in the example of figures 1 to 3 are indicated with identical numerals -2-, -3-, -4-, -5-, while in the zipper higher -1 '- these are also indicated by identical numerals, followed by a premium -2'-, -3'-, -4'-, -5'-.
En la figura 4 se observa un eje a laminar -10- antes de que sendas cremalleras -1-, -1 ''- hagan contacto a través de sendos movimientos longitudinales de sentido opuesto -11-, -12- con la superficie lateral -14- del eje a laminar -10-. Es importante que no se produzca en ningún momento deslizamiento entre el eje a laminar -10- y las cremalleras -1-, -1 ' - - Esto se consigue, según la presente invención, gracias al contacto entre de la superficie lateral -14- del eje a laminar -10- con las tiras -5-, -5'- de las cremalleras .Figure 4 shows a shaft to be laminated -10- before each zippers -1-, -1 '' - make contact through two longitudinal movements of the opposite direction -11-, -12- with the lateral surface - 14- of the axis a laminate -10-. It is important that there is no slippage between the axis to be laminated -10- and the zippers -1-, -1 '- - This is achieved, according to the present invention, thanks to the contact between the lateral surface -14- of the axis to be laminated -10- with the strips -5-, -5'- of the zippers.
Mediante el contacto con las tiras -5-, -5'-, como se muestra en la figura -4-, queda asegurado que los movimientos lineales longitudinales de las cremalleras -11-, -12- quedan sincronizados con el movimiento de giro -13- del eje a laminar -10-, es decir la velocidad de desplazamiento de cada cremallera -1-, -1'- es igual a la velocidad lineal en la superficie lateral -14- del cilindro a laminar -10-. El contacto con la tira o tiras -5-, -5'- de las cremalleras -1-, -1'- se mantiene hasta que la superficie lateral -14- del eje a laminar -10- presentan una profundidad tal que no se produce deslizamiento entre el eje en laminación -10- y las cremalleras -1-, -1'-, recorriendo el eje en laminación -10- la totalidad de las superficie dentadas -3-, -3'- de las cremalleras -1-, -1'-, hasta obtener el eje dentado -10- mostrado en la figura 6. By contacting the strips -5-, -5'-, as shown in Figure -4-, it is ensured that the longitudinal linear movements of the zippers -11-, -12- are synchronized with the turning movement - 13- of the axis to be laminated -10-, that is to say the speed of movement of each rack -1-, -1'- is equal to the linear speed in the lateral surface -14- of the cylinder to be laminated -10-. The contact with the strip or strips -5-, -5'- of the zippers -1-, -1'- is maintained until the lateral surface -14- of the axis to be laminated -10- has a depth such that it is not produces sliding between the rolling axis -10- and the zips -1-, -1'-, running the rolling axis -10- all of the jagged surfaces -3-, -3'- of the zippers -1- , -1'-, until obtaining the toothed shaft -10- shown in figure 6.
