Definitions

  • This invention relates to a pushing tool comprising a slide and a flarer or expander body, used in assembly work according to the preamble of claim 1, for instance of the kind described in User Model No U.9203446 by the same applicant.
  • a pushing tool of this kind is composed of a fixed part with a handle and a hollow through which a sliding part moves, operated by a mobile lever or arm, also attached to the fixed part.
  • the sliding part and the fixed part are each provided with mobile and fixed stops, which move towards or away from each other when the mobile lever or arm is operated.
  • the pushing tool according to the present invention is defined in claim 1. Preferred embodiments are defined in the dependent claims.
  • the slide end opposite to that with the mobile stop, protrudes from the end of the fixed part of the pushing tool when the two mobile and fixed stops approach each other, and it is precisely on this end of the tool, taking advantage of the outward movement of the slide, where the flarer or expander body is located.
  • the body or fixed part includes a supplementary projecting part at its front end, which allows the slide of the pushing tool to pass through, with this supplementary part receiving and securing the flarer or expander.
  • the flarer or expander is a hollow cylindrically-shaped part with an downwardly open end in which the supplementary part attached to the pushing tool is received.
  • This opening allows the flarer to be placed onto the top or upper part of the said supplementary part, in such a way that this supplementary part becomes clasped laterally and frontally inside this said opening.
  • the flarer or expander body is provided with a chamber, also open downwards, into which the slide end of the pushing tool can obtain access.
  • the flarer In front of this chamber and aligned with it, the flarer has another chamber in which a part is housed, in a controlled manner, with the rear end of this part making contact with the end of the slide and the front or forward end being conical in shape.
  • the flarer or expander has a forward portion with a conical enlargement provided with an internal cylindrical slot in which the bases of a number of part, for instance three, are received. These three parts jointly form a complete unit, with each covering an angle of 120o.
  • the exterior of these parts is stepped and rounded, together forming a cylindrical shape with a stepped generatrix.
  • the larger diameter portions of this assembly are those which are housed in the cylindrical slot in the forward part of the flarer or expander and whose interiors are controlled both axially and radially and with the appropriate radial play.
  • the part housed in the intermediate or middle chamber is drawn back towards the pushing tool and, by operating the lever of the pushing tool, the slide acts gradually on the said part, obliging its conical portion to become housed in the conical recess and, later, to open the three sections or segments of the forward part.
  • Figure 1 is a side elevation of a pushing tool that corresponds to the technique covered in User Model U.9203446.
  • Figure 2 is an outer view of the flarer or expander device.
  • Figure 3 is a cross-sectional elevation of the flarer or expander connected to the pushing tool in the rest position.
  • Figure 4 is an elevation of the same in the operating position.
  • the pushing tool (1) is made up of the fixed part (6), equipped with a handle (2) and an upper stop, which is not numbered.
  • the tool has a slide (4) with a stop, not numbered, and is provided with teeth (5), which, on being operated by an internal mechanism by pulling on the lever (3), causes the movement of said slide.
  • This flarer or expander (9), as seen in Fig. 2, is a cylindrical part with a rear portion (10) open downwards (11) in order to receive the projection (7), as well as another intermediate portion and a forward portion (12) where the tube or pipe to be worked is received.
  • FIG. 3 we can appreciate the interior of the flarer or expander, with the free end of the slide housed in the open chamber (13) and close to the rear end (14) of the central part, also housed in the central chamber.
  • the downwardly open chamber (13), together with the opening (11) in the flarer or expander, allow both the projection (7) and the slide end (8) to enter perfectly.
  • the movement of the central part is limited by the washer shown, not numbered, and it moves inside the chamber on its central cylindrical section (15).
  • the forward or front end (16) is conical and becomes inserted into the conical interior (17) of the forward stepped parts (12).

Claims (3)

  1. Un outil étireur, comprenant un coulisseau et un tube ou corps d'expansion, l'étireur provoquant le mouvement de la glissière (4) pour déplacer ensemble deux butées, l'une fixée sur le corps et l'autre sur la glissière elle-même, qui est caractérisée par le fait que à l'extrémité du corps de l'outil (1) par laquelle le bout (8) de la glissière (4) sort, à l'opposé de l'extrémité qui retient la butée mobile, une pièce (7) est fixée et laisse passer la glissière. On trouve logé sur cette glissière la partie arrière du tube ou corps d'expansion (9) qui, à cet effet, dispose d'un trou ouvert vers le bas dont la forme correspond à celle de la glissière, dans la partie adjacente à cette partie arrière, un trou ou une cavité (13) apparaít, aussi dirigé vers le bas, dans lequel l'extrémité de la glissière est logée, avec l'extrémité arrière (14) d'une partie interne (15) guidée dans un boítier cylindrique sortant dans cette cavité, avec cette partie interne qui a aussi une partie cylindrique venant se loger dans le boítier cylindrique décrit et qui termine dans l'extrémité avant en projection cônique (16), qui agit sur l'intérieur cônique correspondant à un ensemble de pièces saillantes ou lèvres (12), sortant de l'ensemble du corps, qui, indépendamment, forment une unité cylindrique avec une génératrice à parliers, dont la partie arrière plus large (19) est logée confortablement dans un ensemble de boítiers circulaires (18) dans la partie avant du tube ou corps d'expansion pour contrôler son ouverture.
  2. Un outil étireur, conformément à la revendication 1, caractérisé par le fait qu'en position repos de l'outil, la partie interne (15) est retirée et que les pièces saillantes ou lèvres (12) sont fermées, la partie interne étant limitée par une rondelle logée dans le boítier cylindrique dans lequel elle se déplace.
  3. Un outil étireur, conformément à la revendication 1, caractérisé par le fait que la partie avant à paliers la plus large (19) des parties avant ou lèvres est contrôlée au début dans le boítier circulaire à l'extrémité avant du tube ou corps d'expansio (9).
