Mandril para bobinas.Chuck for coils.
Objeto de la invención.Object of the invention.
El objeto de la invención es un mandril para bobinas, que comprende un tubo fabricado con cartón, fibra de vidrio, fibra de carbono, plástico, acero, aluminio o cualquier otro material adecuado para bobinar sobre el mismo papel, film o cualquier otro material.The object of the invention is a mandrel for coils, comprising a tube made of cardboard, fiberglass, carbon fiber, plastic, steel, aluminum or any other material suitable for winding on the same paper, film or any other material.
Este mandril presenta unas características orientadas a reforzar los extremos del mismo con el fin de protegerlo de los golpes o rozaduras producidos cuando en los extremos de este tubo se introducen núcleos, topes o mandriles expansibles, tanto en el momento de utilizarse para bobinar los materiales comentados, como en el momento de desbobinarlos para ser tratados en trabajos como impresión, gofrado, corte, rebobinado en bobinas más pequeñas, etc.This mandrel has characteristics oriented to reinforce the ends of the same in order to protect it from bumps or scratches produced when extendable cores, stops or mandrels are introduced at the ends of this tube, both when used to wind the commented materials , as at the time of unwinding them to be treated in works such as printing, embossing, cutting, rewinding in smaller coils, etc.
Campo de aplicación de la invención.Field of application of the invention.
Esta invención es aplicable en el sector dedicado a la fabricación de mandriles para bobinas de productos diversos.This invention is applicable in the sector dedicated to the manufacture of mandrels for coils of various products.
Estado de la técnica.State of the art
Las bobinas de materiales diversos, por ejemplo de lámina de papel o de film plástico, se conforman enrollando el material en cuestión en torno a un mandril conformado por un tubo que además de servir de soporte de la bobina define un pasaje axial para la introducción por sus extremos de núcleos, topes o mandriles expansibles que posibilitan su agarre y manipulación.Coils of various materials, for example of paper sheet or plastic film, are formed by winding the material in question around a mandrel formed by a tube that in addition to serving as a support for the coil defines an axial passage for the introduction by its ends of cores, bumpers or expandable mandrels that allow its grip and manipulation.
La colocación de estos núcleos o topes provocan daños, en muchos casos irreparables, en los extremos del tubo de los mandriles y en poco tiempo dichos mandriles llegan a ser inutilizables para su función inicial. También estos daños pueden provocar riesgos en la seguridad de los tubos al ser alzados mediante puentes grúa o polipastos, al tener la posibilidad de perder la fijación de los topes y caer desde alturas importantes con el peligro del personal responsable de la movilización de las bobinas.The placement of these cores or stops cause damage, in many cases irreparable, at the ends of the mandrel tube and in a short time said mandrels become unusable for their initial function. These damages can also cause risks in the safety of the pipes when they are lifted by crane or hoists, having the possibility of losing the fixation of the stops and falling from important heights with the danger of the personnel responsible for the mobilization of the coils.
El titular de la invención desconoce la existencia de antecedentes de mandriles para bobinas que presenten unas características técnicas, estructurales y constitutivas semejantes a las que presenta el mandril de esta invención y que permitan solucionar el problema planteado.The owner of the invention is unaware of the existence of a background of mandrels for coils that have technical, structural and constitutive characteristics similar to those presented by the mandrel of this invention and that allow solving the problem posed.
Descripción de la invención.Description of the invention
El mandril para bobinas, objeto de esta invención, comprende un tubo de cualquier material abierto por los extremos opuestos y que presenta una superficie exterior y una superficie interior.The mandrel for coils, object of this invention, comprises a tube of any material opened at opposite ends and having an outer surface and an inner surface.
Con el fin de resolver el problema técnico planteado este mandril comprende en cada uno de los extremos del tubo un protector tubular fabricado con un material adecuado para resistir agresiones físicas y/o químicas, que evita el deterioro de los mencionados extremos del tubo.In order to solve the technical problem raised, this mandrel comprises at each end of the tube a tubular protector made of a material suitable for resisting physical and / or chemical aggressions, which prevents the deterioration of the mentioned ends of the tube.
Los protectores tubulares están conformados en un material que presenta una resistencia física y/o química adecuada a la aplicación y uso del mandril, por ejemplo resistencia contra: impactos, abrasión, corrosión, solventes, temperaturas extremas, ácidos u otras sustancias químicas. Algunos de los posibles materiales de fabricación del mandril son: goma natural, goma sintética, plásticos, acero al carbono, acero inoxidable o elastómeros en general.The tubular protectors are made of a material that has adequate physical and / or chemical resistance to the application and use of the mandrel, for example resistance against: impacts, abrasion, corrosion, solvents, extreme temperatures, acids or other chemical substances. Some of the possible manufacturing materials of the mandrel are: natural rubber, synthetic rubber, plastics, carbon steel, stainless steel or elastomers in general.
El tubo presenta en su superficie interior sendos rebajes extremos en los que se encuentran acoplados los protectores tubulares, de modo que en la posición de montaje dichos protectores tubulares presentan una superficie interior coplanaria con la superficie interior del tubo y en uno de sus extremos un reborde exterior que cubre frontalmente el correspondiente extremo del tubo. The tube has on its inner surface two separate recesses in which the tubular protectors are attached, so that in the mounting position said tubular protectors have a coplanar inner surface with the inner surface of the tube and at one of its ends a flange exterior that covers the corresponding end of the tube frontally.
Con las características indicadas los protectores tubulares cubren interior y frontalmente los extremos del tubo del mandril, incrementando su resistencia y consiguientemente la vida útil del mismo.With the indicated characteristics, the tubular protectors cover inside and frontally the ends of the mandrel tube, increasing its resistance and consequently its useful life.
Las características de la invención se comprenderán con mayor facilidad a la vista del ejemplo de realización mostrado en las figuras adjuntas que se describen a continuación.The features of the invention will be more readily understood in view of the exemplary embodiment shown in the accompanying figures described below.
Descripción de las figuras.Description of the figures.
