Other modes of realization are not discarded at all in which accessory changes are introduced that do not detract from its foundation.
El objeto del invento se refiere a mejoras en cortatubos con calibrador y escariador/biselador de los bordes del tubo cortado, estructurados segun la patente principal P201630276.The object of the invention relates to improvements in pipe cutters with calibrator and reamer / beveller of the edges of the cut pipe, structured according to the main patent P201630276.
La solution tecnica objeto del invento, al igual que en la patente principal, se aplica en un cuerpo (I) de cortatubos y permite, primero calibrar los bordes cortados para volver a dejar su diametro igual que el del resto del diametro interior del tubo (t) y despues, en una misma operation, biselar y escariar el borde cortado de los tubos (t). Las operaciones de biselar y escariar se realizan por el interior del borde cortado de un tubo (t).The technical solution object of the invention, as in the main patent, is applied in a pipe-cutter body (I) and allows, first calibrating the cut edges to re-leave their diameter equal to that of the rest of the inner diameter of the pipe ( t) and then, in the same operation, bevel and ream the cut edge of the tubes (t). Beveling and reaming operations are performed inside the cut edge of a tube (t).
Adicionalmente, y al igual que en la patente principal, esta solucion tecnica posibilita que en un mismo cortatubos sea posible calibrar, biselar y escariar tubos (t) de diametros diferentes.Additionally, and as in the main patent, this technical solution makes it possible to calibrate, bevel and ream tubes (t) of different diameters in the same pipe cutter.
De conformidad con la invention se dispone, al menos, un calibrador (11) en el cuerpo (1) del cortatubos; siendo cada calibrador (11) un elemento independiente que se fija en el cuerpo (1) empleando tornillos (3), remaches o similares.According to the invention, at least one gauge (11) is provided in the body (1) of the tube cutter; each gauge (11) being an independent element that is fixed to the body (1) using screws (3), rivets or the like.
El calibrador (11), o cada calibrador (11) si hay varios, se estructura en un cuerpo de revolution que define en su perimetro una zona rebajada en rampa (110) donde se conforma o incorpora directamente al menos una cuchilla (21) de escariar/biselar. Cada calibrador (11) integra en si mismo las cuchillas (21), existiendo al menos tantas cuchillas (21) como calibradores (11).The gauge (11), or each gauge (11) if there are several, is structured in a revolution body that defines in its perimeter a recessed area in ramp (110) where it is formed or incorporated directly at least one blade (21) of reaming / beveling. Each calibrator (11) integrates in itself the blades (21), there being at least as many blades (21) as calibrators (11).
De conformidad con la invencion se disponen, al menos, dos calibradores (11) de diferentes diametros. Estos calibradores (11) quedan alineados delimitando entre dos de ellos, y/o entre uno de ellos y el propio cuerpo (1) del cortatubos, al menos dos cavidades (12) susceptibles de admitir extremos de tubos (t) de diametros diferentes, que se posicionan en un correspondiente calibrador ( I I ) . According to the invention, at least two calibrators (11) of different diameters are arranged. These calibrators (11) are aligned by delimiting between two of them, and / or between one of them and the body (1) of the tube cutter, at least two cavities (12) capable of admitting tube ends (t) of different diameters, which are positioned in a corresponding calibrator (II).
Segun la realizacion representada, se disponen tres calibradores (11) alineados y fijados en el cuerpo (1) con tomillos (3), remaches o similares. Ver figura 2.According to the represented embodiment, three calibrators (11) aligned and fixed on the body (1) are arranged with screws (3), rivets or the like. See figure 2.
En este ejemplo de realizacion se han dispuesto tres calibradores (11) que, en conjuncion con el cuerpo (1) del cortatubos, delimitan tres cavidades (12): una en torno a cada calibrador (11) siempre considerando que el inter-espacio comun delimitado por dos calibradores (11) contiguos forma parte de una u otra cavidad (12) segun que el tubo (t) se inserte en uno u otro calibrador (11). Cada cuchilla (21) integrada en un mismo calibrador (11) alcanza una correspondiente cavidad (12).In this exemplary embodiment, three calibrators (11) are arranged which, in conjunction with the body (1) of the tube cutter, delimit three cavities (12): one around each calibrator (11) always considering that the common interspace delimited by two adjacent calibrators (11) forms part of one or another cavity (12) according to whether the tube (t) is inserted in one or the other calibrator (11). Each blade (21) integrated in a same calibrator (11) reaches a corresponding cavity (12).
En general, conformando "n" calibradores (11) existen como mmimo “n” cuchillas y se delimitan "n" cavidades (12) con lo que en un mismo cortatubos se pueden escariar/biselar tubos (t) de "n" diametros diferentes.In general, forming "n" calibrators (11) there are at least "n" blades and "n" cavities (12) are delimited so that in the same cutter can be rebounded / beveled tubes (t) of "n" different diameters .
Con esta estructuracion, componentes y particularidades, cuando el borde calibrado de un tubo (t) avanza en la correspondiente cavidad (12), las cuchillas (21) integradas en el correspondiente calibrador (11) alcanzan una misma cavidad (12) para realizar el escariado/biselado por el interior del tubo (t).With this structure, components and features, when the calibrated edge of a tube (t) advances in the corresponding cavity (12), the blades (21) integrated in the corresponding calibrator (11) reach the same cavity (12) to perform the reaming / beveling inside the tube (t).
La cantidad de tubos (t) de diametros diferentes que se puedan calibrar y escariar/biselar en un mismo cortatubos viene limitada, exclusivamente, por las dimensiones fisicas del propio cuerpo (1) del cortatubos.The number of tubes (t) of different diameters that can be calibrated and reamed / beveled in a single tube cutter is limited, exclusively, by the physical dimensions of the body (1) of the tube cutter.
Podran ser variables los materiales, dimensiones, proporciones y, en general, aquellos otros detalles accesorios o secundarios que no alteren, cambien o modifiquen la esencialidad propuesta.The materials, dimensions, proportions and, in general, those other accessory or secondary details that do not alter, change or modify the essentiality proposed may be variable.
Los terminos en que queda redactada esta memoria son ciertos y fiel reflejo del objeto descrito, debiendose tomar en su sentido mas amplio y nunca en forma limitativa. The terms in which this report is written are true and faithful reflection of the described object, should be taken in its broadest sense and never in a limiting manner.
