    Improvements in pipe cutters with calibrator and reamer/beveling of the edges of the cut pipe, structured the pipe cutter according to the main patent and characterized the improvements because at least one gauge (11) is provided in the body (1) of the pipe cutter; each gauge (11) being an independent element that is fixed to the body (1) using screws (3), rivets or the like. Preferably several calibrators (11) aligned and of different diameters are arranged. Each calibrator (11) integrates in itself the blades (21), there being at least as many blades (21) as calibrators (11). Between the calibrator (11) and the body (1) of the tube cutter, and between each two calibrators (11) aligned, cavities (12) are delimited. When the calibrated edge of the tube (t) advances in the corresponding cavity (12), the blades (21) of the corresponding calibrator (11) perform the reaming/beveling inside the tube (t).

    Improvements in pipe cutters with calibrator and reamer / bevel of the edges of the cut tube.
    DESCRIPTION
    Object of the invention
    The object of the invention relates to improvements in pipe cutters incorporating at least one gauge and at least one reamer / bevel in the pipe cutter body itself; structured in accordance with the object of the main patent P201630276, referred to a pipe cutter with gauge and reamer / bevel of the edges of the cut tube.
    The background of the invention known to the applicant, and the technical problem to be solved, have already been described in the Main Patent. The improvements of this application are applied in the object of said patent and basically materialize in that:
    - now the bevel is removed as such; in the main patent is an independent part / element that is attached to the body of the pipe cutter.
    - each calibrator is now an independent element that is fixed to the body of the pipe cutter using screws, rivets or the like; in the main patent the calibrator, or the calibrators
    15 If there are several, they are formed forming a unique whole with the main body.
    - now each calibrator integrates in itself the reaming / beveling blades, there are as many blades as there are calibrators; In the main patent the blades are formed in the bevel.
    Description of the invention
    The object of the present addition offers a new technical solution that simplifies the manufacture of the body of the pipe cutter and the calibrators. It also suppresses the need for the bevel (the blades are integrated in the gauge itself).
    However, the way of solving the problem of re-calibrating the cut edges of the tubes (which have been deformed during the cutting operation) and eliminating the burrs in them is maintained; at the same time as it makes an internal reaming / chamfering of said cut edges of the tube.
    The improvements object of the invention are characterized in that:
    a) at least one gauge is provided in the body of the pipe cutter; each calibrator being an independent element that is fixed in the body of the pipe cutter using thymes, rivets or the like;
    b) each calibrator integrates the reamer / bevel blades itself, with at least 5 as many blades as calibrators.
    They are also characterized in that each caliper is structured in a body of revolution that defines in its perimeter a recessed area in ramp where at least one reaming / beveling blade is formed or incorporated directly.
    They are also characterized in that at least two 10 aligned calibrators of different diameters are arranged in the body of the pipe cutter. Between two of these calibrators, and / or between one of them and the pipe cutter body itself, at least two cavities are delimited that can admit ends of tubes of different diameters, which are positioned in a corresponding calibrator; so that when the calibrated edge of the tube advances in the corresponding cavity, the blades of the gauge perform the reaming / chamfering inside the tube.
    15 All other technical and constructive features and particularities of the main patent that are compatible with the new technical solution subject to the application are maintained.
    Other configurations and advantages of the invention can be deduced from the following description, and from the dependent claims.
    Description of the drawings
    In order to better understand the object of the invention, a preferred embodiment is shown in the figures, susceptible to accessory changes that do not detract from its foundation. In this case:
    Figure 1 represents a schematic sectional general view of the object of the invention, for an exemplary embodiment that includes three calibrators (11) fixed with screws (3), rivets or similar to the body (1) of the pipe cutter; and each of which defines a ramp zone (110) that integrates a blade (21).
    Figure 2 represents a detailed longitudinal section in plan to observe the cavities (12) and the fixing of the calipers (11) to the body (1) of the pipe cutter.
    Figure 3 represents a schematic view in enlarged detail, to observe the integration of the blades (21) in the calipers (11).
    In figure 3 a tube (t) in operative position is shown in strokes.
    Detailed description of a preferred embodiment
    An example of practical, non-limiting embodiment of the present invention is described below. Other embodiments in which accessory changes are introduced that do not distort its foundation are not ruled out at all.
    The object of the invention relates to improvements in pipe cutters with calibrator and reamer / chamfering of the edges of the cut tube, structured according to the main patent P201630276.
    The technical solution object of the invention, as in the main patent, is applied in a body
    (I) of pipe cutters and allows, first, to calibrate the cut edges to return their diameter just like the rest of the inner diameter of the tube (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).
    Additionally, and as in the main patent, this technical solution makes it possible to calibrate, chamfer and ream tubes (t) of different diameters in the same pipe cutter.
    In accordance with the invention, at least one gauge (11) is disposed in the body (1) of the pipe cutter; each calibrator (11) being an independent element that is fixed in the body (1) using screws (3), rivets or the like.
    20 The calibrator (11), or each calibrator (11) if there are several, is structured in a body of revolution that defines in its perimeter a lowered area in ramp (110) where at least one blade (21) is formed or incorporated directly of reaming / beveling. Each calibrator (11) integrates in itself the blades (21), there being at least as many blades (21) as calibrators (11).
    In accordance with the invention, at least two calibrators (11) of different diameters are arranged. These calibrators (11) are aligned, delimiting between two of them, and / or between one of them and the body (1) of the pipe cutter, at least two cavities (12) capable of admitting pipe ends (t) of different diameters, that are positioned in a corresponding calibrator
    (II).
    According to the embodiment shown, three calibrators (11) are aligned and fixed in the body (1) with thymes (3), rivets or the like. See figure 2.
    In this exemplary embodiment, three calibrators (11) have been arranged which, in conjunction with the body (1) of the pipe cutter, delimit three cavities (12): one around each calibrator (11) 5 always considering that the inter-space common delimited by two adjacent calibrators (11) is part of one or another cavity (12) according to which the tube (t) is inserted into one or another calibrator (11). Each blade (21) integrated in the same caliper (11) reaches a corresponding cavity (12).
    In general, forming "n" calibrators (11) there are at least "n" blades and 10 "n" cavities (12) are delimited, so that in the same pipe cutter tubes (t) of "n" can be reamed / chamfered
    different diameters
    With this structuring, components and particularities, 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 / chamfering inside the tube 15 (t).
    The quantity of tubes (t) of different diameters that can be calibrated and reaming / chamfering in the same pipe cutter is limited, exclusively, by the physical dimensions of the body (1) of the pipe cutter itself.
    The materials, dimensions, proportions and, in general, those other 20 accessory or secondary details that do not alter, change or modify the proposed essentiality may be variable.
    The terms in which this report is written are true and faithful reflection of the object described, and should be taken in its broadest sense and never in a limiting way.
