Definitions
- the invention relates to the connection of tubes, and more specifically, the devices for making sockets on plastically deformable tubes.
- a socket designates the connection of two tubes of diameters substantially equivalents by fitting one tube into the other or by fitting tubes and an intermediate piece.
- a female socket designates a slight increase in the inside diameter of a tube over a given length, which can be produced by plastic deformation.
- plastic deformation carried out on a tube or on the intermediate piece.
- socket is used to designate a female socket produced by plastic deformation.
- the assembly by socket applies in particular to the assembled copper tubes by welding or soldering, or to synthetic tubes connected by inserts.
- the fitting of the fitting therefore requires a slight increase the inside diameter of the tube in order to introduce the fluted insert without difficulty.
- This increase in diameter is obtained by plastic deformation. To avoid bead formation (which is unsightly and increases the effort of mounting) when installing the ring, this increase in diameter must be precise in diameter but especially in length.
- the JR company markets a pliers with tilting by two metal sectors.
- This shouldered tool of the J.R pliers type, consists of two articulated handles and a mouthpiece.
- the tip consists of two stacks of half-cylinders of different diameters, which are articulated at the level of a generator of their peripheral surface.
- We make the socket by introducing the tip into the tube to be deformed, then by applying successive pressures on the handles. We do thus rotate the half-cylinders between them and these thus deform the tube to form a socket.
- This clamp can be used for different diameters but it is mainly intended for forming casings on copper tube annealed before fitting and brazing.
- the instructions for use with the annealed copper tube recommend a progressive action with rotation of the nozzle in the tube.
- the SAPER company also markets multi-sector socket pliers.
- the tip is cylindrical, made up of several metal sectors deviating under the action of a cone. A set of sectors is reserved for only one tube diameter to be deformed. Switching to a different diameter tube requires thus the change of the complete nozzle. This tool is more precise than the previous, with a higher cost in return.
- the document GB-639 103 describes a socket training device.
- This device consists of a matrix, a tip and an actuation key the mouthpiece.
- the matrix is formed by two articulated parts defining the profile final exterior of a tube.
- the articulated parts also define a stop for the end of the tube and a stop for the actuation key.
- the activation key is consisting of a cylindrical sleeve with an internal thread and a bar passing through the sleeve and arranged perpendicular to the sleeve.
- Buffer comprises a threaded cylindrical rod integral with a piston. A tampon is placed against the piston and surrounds an unthreaded part of the rod. Key rotation causes compression of the buffer between the piston and the tube stop. Buffer thus widens radially.
- the document JP09193250 describes a process for forming an enclosure.
- the end of a polyethylene tube is heated.
- This rod ends with a stop in contact with the tampon.
- Another stop is brought into contact with the pad.
- a cylinder pulls on the rod. The pad is thus compressed between the stops and widens radially.
- the document FR-A-2 380 831 describes a tool for forming an socket comprising an expandable mandrel fitting into the tube.
- This chuck is consisting of several segments linked together elastically. These segments form a conical axial passage for the passage of a conical needle. The pull of the needle causes the radial expansion of the mandrel.
- Document EP-A-0 397 570 describes an apparatus for forming sockets. This device has a fixed handle with movable jaws, a chuck conical end and a movable handle articulated on the mandrel by a pivot. The movable handle is also connected by a link, offset from the axis of the mandrel, with movable handle.
- the invention proposes a solution to these various problems; she offers a pliers fitted with a nozzle making it possible to obtain both uniform deformation of the tube and high deformation precision, both in length and in diameter.
- the invention allows simplified handling during the production of the socket.
- the invention also improves the service life of the pliers and of the tips.
- the invention also allows to obtain a conical socket bottom.
- the invention relates to an interlocking clamp comprising an end piece with an elastomeric pad, an axial stop, a through shaft said pad, the shaft driving the stop in translation towards the pad when it is stressed, a thrust washer pierced with a hole through which the shaft passes, means for traction of the shaft, opposite the hole, the traction means having a body with a handle and a through cavity formed in the body, said washer stop substantially closing one end of the cavity, a piston sliding in said cavity, in which are provided means for coupling the shaft, a lever mobile mounted for rotation on the handle and one end of which biases the piston.
- the end of the lever is separable from the piston.
- the lever is rotatably mounted on the handle by at least one link.
- the tampon is of substantially cylindrical shape.
- the stop comprises a circular face of diameter substantially equal to the diameter of the tampon.
- the stop is metallic.
- the pad comprises several elastomeric washers.
- metal washers are interposed between elastomeric washers.
- each tampon has a hardness of between 50 and 110 Shore A.
- the invention proposes to achieve a socket in a tube, to compress axially inside the tube and between two stops an elastomeric pad, for cause its radial widening.
- the radial deformation of the tampon causes the formation of the socket when the pad comes into contact with the wall of the tube in which it is inserted.
- the invention also provides a device facilitating compression buffer between the two axial stops.
- the invention thus makes it possible to achieve a localized increase in diameter of a tube, uniform and of high precision, with a simple handling tool and long life. Tests have shown that the tip is held better than 50,000 operations. The tool body has withstood over 250,000 operations without failure.
- Figure 1 is a schematic sectional view of a socket pliers, a end piece and a tube, before forming a socket according to the invention.
- the figure shows in section a tube 1, at the end of which is inserted a nozzle 2.
- This tip includes a stop 3, a shaft 5 and an elastomeric pad 4.
- a clamp 6 coupled to the endpiece, which is described in detail below.
- An elastomeric pad here designates a pad which is both incompressible, but deformable.
- the fact that the tampon is incompressible ensures that it deforms radially when it is axially stressed in compression by the stop and by the clamp, as explained below; preferably, the variation in volume of the buffer, when is subjected to a pressure of 50 MPa, is less than 5%. This value ensures that the deformation of the tampon effectively causes deformation of the tube in which the tip is inserted.
- the fact that the pad is deformable ensures that it deforms radially when it is compressed, and when it exerts a pressure substantially constant over the entire inner surface of the tube with which it is in contact.
- the stamp comprises two faces, substantially perpendicular to the axis of the end piece and parallel: the first face is in contact with the stop 3, the second face is a free face.
- the first face is in contact with the stop 3
- the second face is a free face.
- it has a substantially cylindrical shape, which corresponds to the inner straight section of the tube.
- the stop 3 is disposed against one face of the pad 4, and extends substantially on the entire face of the tampon. Its function is to transmit an axial force of compression on the tampon.
- the shaft 5 crosses the buffer and is connected to the stop 3 of so as to allow it to transmit to the buffer 4 a force exerted on the shaft. can transmit an axial force on the stop 3.
- the shaft 5 is a piece of low-cut steel, which is screwed onto the stop 3.
- the tensile force is transmitted to the stop.
- the stop therefore exerts a force on the tampon.
- a second stop described later, against the free face of the pad, we compress axially the buffer between these two stops, and a radial expansion is thus generated buffer.
- the pad is deformable, so we can vary its length.
- a decrease in its length therefore implies a increase in its diameter.
- the axially compressed pad extends radially as and when the compression imposed on it, and radially stresses the tube in which it is inserted. The radial force is exerted by the buffer on the walls of the tube against which the periphery of the buffer abuts.
- a buffer is preferably chosen made of an elastomeric material, for its deformability and incompressibility properties, such as for example a silicone derivative or a polyurethane.
- elastomeric material for its deformability and incompressibility properties, such as for example a silicone derivative or a polyurethane.
- pads of substantially cylindrical shape because the pad thus comes directly into contact with the entire surface to be deformed. More generally, the pad section preferably corresponds to the inner section of the tube to be deformed, with a clearance allowing the introduction of the buffer into the tube.
- An additional advantage of the tampon according to the invention is that due to the deformability of the elastomeric pad, the junction 15 between the socket 16 and the rest of the tube is progressive and conical.
- the stop 3 of the nozzle has the function of axially compressing one face of the pad, and more specifically the side of the pad which is pressed into the tube.
- the stop is chosen with a circular compression face, of diameter substantially equal to the diameter of the tampon, so as to compress the most large pad area possible.
- the diameter of a cylindrical pad used is very close to the initial diameter of the portion of tube to be deformed. So if we uses a stop diameter close to the diameter of the buffer, an axial creep is avoided of the buffer during compression, harmful to the operation of the device.
- the stop is metallic to allow good transmission of the compression forces imposed on the buffer. We can finally realize a rounded projection on the free face of the tampon, to facilitate its insertion at inside the tube.
- the stop has fixing means on the shaft 5, so that transmit the forces exerted by the shaft to the elastomer pad.
- the function of the shaft is to transmit a compression force of the mouthpiece. It can therefore have any shape. Having it in the center of the tampon avoids limiting the radial deformation of the tampon.
- the shaft has fixing means on the stop, in the example a thread of its end.
- the invention also provides a clamp 6 intended to exert traction on the shaft 5 of the nozzle and provide a stop complementary to the stop of the nozzle.
- the structure of this clamp will appear more clearly from the following description of operation of a tip coupled to a clamp.
- An example of realization of a such pliers are shown in FIG. 3.
- the pliers 6 comprises a body 7 with a handle 13, a lever 8, a piston 9, a link 10, a compression stop 11 and a dowel 17.
- the body 7 is made of treated steel. It defines a cavity 12 passing through it in part, and is fixed to the end of a handle 13.
- the piston 9 is shaped to slide in the cavity 12 and protrudes from one end of the cavity.
- On a part protruding from this piston is mounted a pin 17, which serves for hooking the lever 8.
- the end of the lever 8 is fork shaped and has two ends parallel planes each with a recess into which one end of the pin 12. The lever can thus pivot around this pin, while driving it. Conversely, the lever 8 can easily be released from the end of the piston.
- a rod 10 pivots at one of its ends around an axis of lever 8, which is close of its fork shaped end. This link 10 pivots at its other end around an axis of the handle 13.
- This link can be doubled by one second rod placed symmetrically on the other side of the lever 8 and of the handle 13.
- the handle 13 is integral with body 7 and extends substantially radially relative to the common axis of the piston 9 and of the cavity 12.
- the second end of the cavity 12 is partially closed by a washer 11. This washer is drilled so as to leave pass the tree 5.
- the piston has means for fixing the free end of the shaft to a mouthpiece. It can simply be a tapped hole, allowing the mounting of the shaft by screwing.
- the lever 8 is hooked on the end of the piston.
- the nozzle can be introduced at the end of a tube; previously the tube if necessary, cut to the right length, well perpendicularly.
- the tip is pressed into the tube, so that the end of the tube comes into contact with the washer 11 of the clamp, and that the elastomeric pad is entirely in the tube.
- This configuration is shown in Figure 1.
- the shaft 5 is urged traction, which has the effect of compressing the buffer between the stop 3 and the washer 11, and thus increase the diameter of the buffer. It follows an expansion of the diameter of the tube to the right of these washers, and a plastic deformation of the tube.
- the passage from one diameter to another is done by simple replacement of the end piece, by spacing the handles, detaching the end piece in place, and hanging it of the new tip.
- the tubes that can be formed with the tool are in particular copper tubes annealing with a diameter of 12 mm to 20 mm, or tubes made of synthetic materials from DN 12 to DN 25 in series 5, from DN 16 to DN 25 in series 3.2, tubes of minimum thickness from 2mm from DN12 to DN22, or the metal core composite tubes from DN 14 to DN22.
- the following table shows examples of characteristics of tubes to be enlarged, as well as the dimensions of these tubes after expansion according to the invention: DN 5 series 2 mm mini series 3.2 series DImini Dexp Lexp DImini Dexp Lexp DImini Dexp Lexp 12 9 10.85 11 7 8.75 11 16 12.2 14.05 11 11 12.85 11 10.6 12.35 11 20 15.4 17.25 11 15 16.85 11 13.4 14.95 11 25 19.4 21.8 16.4 19.4 21.8 16.4 17 18.55 16.4 DN Nominal outside diameter of the tube. DImini Minimum inside diameter of the tube. Dexp Internal diameter of the tube after expansion. Lexp Expanded tube length.
- the socket produced according to the invention reduces the risk of thinning or localized bleaching.
- the invention makes it possible to reduce the risk of producing sockets defective.
- the socket has an expansion of uniform diameter over the entire periphery of the tube, with an absence of any generator preferably requested.
- the progressive deformation of the buffer allows for a bottom case conical, which is particularly useful when using inserts fitting, such as barbed fitting inserts.
- the bottom cone allows thus forming a stop for the insert. This cone also allows the wedging of this insert and thus prevents the fitting from dropping unexpectedly during handling phases later.
- the invention is of course not limited to the embodiments described.
