Description

Protector de flejes para troqueles.Strip guard for dies.

Object of the invention

La presente invención se refiere a un protector que ha sido especialmente concebido para ser utilizado en troqueles rotativos, concretamente para proteger los extremos de los correspondientes flejes troqueladores, cuando éstos alcanzan el borde de la pieza de madera que los sustenta.The present invention relates to a protector which has been specially designed to be used in dies rotating, specifically to protect the ends of corresponding punching strips, when they reach the edge of the piece of wood that supports them.

El objeto de la invención es evitar que dichos flejes puedan resultar dañados en las maniobras de transporte y/o almacenamiento de los troqueles en las estanterías.The object of the invention is to prevent said strapping may be damaged in transport maneuvers and / or Storage of the dies in the shelves.

Background of the invention

Los troqueles del tipo citado están constituidos a partir de un soporte cilíndrico, generalmente de madera, a base de dos piezas o "tejas", normalmente de madera contra-chapada, destinadas a adaptarse al bombo porta-troquel asimismo cilíndrico, contando éstas "tejas" con ranuras u orificios que permiten la implantación y fijación de los flejes troqueladores, que pueden materializarse en cuchillas u otros elementos en función de que se pretenda obtener una operación de corte, de hendido, de perforado, etc.The dies of the aforementioned type are constituted from a cylindrical support, usually made of wood, based two pieces or "tiles", usually made of wood counter-plated, intended to adapt to the hype also cylindrical die holder, counting these "tiles" with grooves or holes that allow implantation and fixation of the die-cut strips, which can materialize in blades or other elements depending on which one intends to obtain a cutting, creasing, drilling operation, etc.

En el caso habitual de que el troquel esté compuesto por dos maderas, en correspondencia con las líneas de unión de tales maderas, en los flejes se extienden hasta el borde libre de las mismas, de manera que resultan elementos sobresalientes, que frecuentemente resultan dañados durante las manipulaciones de los troqueles, concretamente durante el almacenaje y transporte de los mismos, ya que son relativamente frecuentes impactos del troquel contra la plataforma o el montante de las estanterías, impactos que se producen precisamente a través de los extremos de los flejes.In the usual case that the die is composed of two woods, in correspondence with the lines of union of such woods, in the strips they extend to the edge free of them, so that elements are outstanding, which are frequently damaged during handling of the dies, specifically during storage and transport thereof, since they are relatively frequent impacts of the die against the platform or the upright of the shelves, impacts that occur precisely through of the ends of the straps.

Description of the invention

El protector que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, evitando el deterioro por impacto de los extremos de los flejes.The protector proposed by the invention resolves in a fully satisfactory way the problem previously exposed, avoiding the deterioration by impact of the ends of the Straps

Para ello y de forma mas concreta dicho protector se materializa en una pieza elásticamente deformable, capaz de absorber posibles impactos, que con cualquier configuración exterior presenta una ranura o corte a través del que se acopla también elásticamente a la extremidad del fleje, de manera que dicha extremidad queda perfectamente protegida tanto por su borde libre como por sus caras laterales.To do this and more specifically said protector materializes in an elastically deformable piece, able to absorb possible impacts, than with any exterior configuration features a groove or cut through which it also elastically attaches to the tip of the strap, of so that this limb is perfectly protected both by its free edge as by its lateral faces.

Para facilitar la deformabilidad elástica del protector y alargar la vida útil del mismo, se ha previsto que el citado corte o ranura se expanda en su fondo con una configuración cilíndrica, evitando la existencia de aristas que pudieran constituir líneas de arranque para la formación de fisuras.To facilitate the elastic deformability of the protector and extend its life, it is expected that the said cut or groove expand in its bottom with a configuration cylindrical, avoiding the existence of edges that could constitute starting lines for cracking.

Las dimensiones del protector serán tales que su efecto amortiguador quede asegurado frente a los impactos que han de producirse habitualmente, así como también para cubrir de forma sobredimensionada el extremo del fleje, tanto en su borde frontal como en su borde exterior y operativo.The dimensions of the protector will be such that its damping effect is assured against the impacts that have to occur regularly, as well as to cover oversized the end of the strap, both on its front edge as on its outer and operational edge.

Description of the drawings

Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

La figura 1.- Muestra, según una vista general en perspectiva, un protector de flejes para troqueles realizado de acuerdo con el objeto de la presente invención.Figure 1.- Shows, according to an overview in perspective, a die strap protector made of according to the object of the present invention.

La figura 2.- Muestra, también según una vista en perspectiva, un detalle parcial de un troquel que incorpora el protector de la figura anterior, debidamente montado sobre uno de los flejes del troquel.Figure 2.- Shows, also according to a view in perspective, a partial detail of a die that incorporates the protector of the previous figure, duly mounted on one of die strips.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas y en particular de la figura 2, puede observarse como el protector que la invención propone está destinado a troqueles cilíndricos en los que participan al menos dos maderas (1), a modo de "tejas" semicilíndricas, a cuya superficie externa están debidamente fijados los flejes (2), que como anteriormente se ha dicho pueden tener una función de cuchillas de corte, de perforadores lineales, etc.In view of the figures outlined and in particular of figure 2, can be seen as the protector that The proposed invention is intended for cylindrical dies in the involving at least two woods (1), as "tiles" semi-cylindrical, to whose outer surface they are properly fixed the strips (2), which as mentioned above may have a function of cutting blades, linear perforators, etc.

Dado que en muchas ocasiones los flejes (2) deben establecer una perfecta continuidad en el perímetro del troquel, dichos flejes (2) llegan hasta el borde libre (3) de las maderas o soportes (1), de manera que sus extremos (4) constituyen elementos prominentes sobre los que, como anteriormente se ha dicho, se producen impactos en la manipulación de los troqueles.Since in many occasions the strips (2) they must establish a perfect continuity in the perimeter of the die, said strips (2) reach the free edge (3) of the wood or supports (1), so that its ends (4) constitute prominent elements on which, as previously said, impacts on the manipulation of dies

Pues bien, el protector que la invención propone se materializa en un cuerpo (5) de naturaleza apropiada para absorber los posibles impactos evitando las deformaciones en los extremos (4) de los flejes (2), cuerpo (5) afectado por una ranura (6) infradimensionada con respecto al espesor de los flejes (2), en orden a que el protector constituya una especie de pinza elástica que no requiere de otros medios de fijación a los flejes (2), tal como muestra la figura 2.Well, the protector that the invention proposes it materializes in a body (5) of an appropriate nature to absorb the possible impacts avoiding deformations in the ends (4) of the strips (2), body (5) affected by a groove (6) under-sized with respect to the thickness of the strips (2), in order that the protector constitutes a kind of elastic clamp which does not require other means of attachment to the straps (2), such as shown in figure 2.

Por otro lado la anchura de la pieza (1) debe ser al menos coincidente con la anchura de los flejes (2), preferentemente algo mayor, para proteger simultáneamente el borde longitudinal y libre de dichos flejes.On the other hand the width of the piece (1) must be at least coincident with the width of the strips (2), preferably somewhat larger, to simultaneously protect the edge longitudinal and free of said strips.

Dado que los protectores (5) deben ser desacoplados de los troqueles cada vez que éstos se usan, y vueltos a implantar tras la citada utilización, se ha previsto que la ranura (6) se remate en su fondo en una pequeña expansión cilíndrica (7) que evita que en las normales deformaciones elásticas del protector la ranura (6) se prolongue por esta zona de fondo produciéndose su fragmentación.Since the protectors (5) must be decoupled from the dies each time they are used, and returned to be implemented after said use, it is expected that the slot (6) is auctioned at its bottom in a small expansion cylindrical (7) that prevents normal deformations elastic of the protector the groove (6) is extended by this zone of background producing its fragmentation.

En el ejemplo de realización práctica mostrado en las figuras el citado cuerpo (5) del protector se remata, por su zona opuesta al acceso a la ranura (6), en un frente semicilíndrico (8) que resulta idóneo para la absorción tanto de impactos longitudinales con respecto al fleje, como de impactos laterales, pero obviamente esta configuración puede variar sin que ello afecte a la esencia de la invención.In the example of practical embodiment shown in the figures the said body (5) of the protector is finished off, by its area opposite the access to the groove (6), on a semi-cylindrical front (8) which is ideal for the absorption of both impacts longitudinal with respect to the strip, as of lateral impacts, but obviously this configuration can vary without affecting to the essence of the invention.

El protector puede estar obtenido a base de cualquier material que absorba los impactos, como anteriormente se ha dicho, y en este sentido estará preferentemente materializado en un bloque de un material elastomérico, dada la larga vida útil prevista para el mismo.The protector can be obtained based on any material that absorbs impacts, as previously said, and in this sense it will be preferably materialized in a block of an elastomeric material, given the long service life planned for it.
