Definitions

  • the present invention relates to a tool device for ogiver and flow round tubes of round and / or ovoid section.
  • the flow-forming makes it possible to modify the profile a part by rotating it axially while at minus a scroll wheel, or the like, animated by a movement of translation and applied to said part, causes spinning helical which deforms said part.
  • Document EP 0769337 presents a method for sealing the end of a steel tube, the principle of which is to apply a force radial on the outer surface of the tube, close to end to close and then move the application area of force, continuously both circumferentially and radially with respect to said tube, so as to produce a progressive inward deformation of the side wall of this until its end is completely closed.
  • Document US 2,408,596 relates to another device intended to close the end of a tube.
  • This device combines the axial rotation of the tube and the heating thereof with the displacement in an arc, in a back and forth movement, a roller type tool, rolling on the end of said tube.
  • the document EP 0695593 also describes a device for the closure by flow turning of an open end of a tube.
  • the tube is engaged in a bore and comes into contact successively, according to its depression, pairs of rollers conical from different angles, more and more open with the axis of said tube according to their position in the longitudinal direction.
  • the rotation of the tube and the axial thrust exerted on it, allow to gradually close the end of the tube.
  • WO 96/13347 also relates to an apparatus for narrowing of one end of a metal tube to form part of an arched wall. It includes a means to rotate the tube on its axis, a mobile means designed to heating a terminal part of the tube and a bending means.
  • the heating means consists of an induction coil placed at the end of a telescopic arm, itself pivotally mounted, while the bending means consists of an arm supporting a wheel and pivotally mounted on a first slide fixed on a second slide.
  • the bending wheel successively described trajectories in fact constituting successive tangents of the desired final profile.
  • the devices described in these documents have many disadvantages, besides that they do not allow to obviate and to spin tubes of section other than round, the bending tools wear out quickly, especially due to working conditions at high temperatures, and because they are often subjected to a pressure exerted in overhang, i.e. that the contact point is not in the axis of the thrust.
  • the flow forming tools used consist of essentially in rotating mobile elements of the type rollers mounted on bearings, which wear out very quickly.
  • the object of the present invention is to propose a device tool for ogivering and spinning round section tubes and / or ovoid to remedy the various drawbacks supra.
  • the tool device for ogivering and rotating tubes is of the type comprising at least one wheel, or analogous, moved in translation and applied to the ogiver or flow tube, and it is characterized essentially in that it has a support element in a end of which is provided a cage suitable for receiving and retain a circular active element, mobile in revolution on itself in said cage, and part of which emerges from this last.
  • the active element is supported on at least one sliding shoe made of a hard material.
  • the device flow forming tool comprises means for cooling the active element.
  • the cooling means of the active element consists of means capable of delivering a fluid, such as air, in the cage, and opening back of said active element, at the level of the sliding pad (s) by example.
  • the active element has a shape spherical.
  • the spherical element consists of a ball which can rotate in all the senses, which has the particular advantage of not have to worry about the angular orientation of the tool like this is the case with a wheel.
  • the active element is in the form of a pebble, the edge of which is of semi-circular cross section.
  • the active element is made of ceramic.
  • a blocking means is therefore provided. able to come into contact with the active element to immobilize it.
  • This active element can for example consist, for an element active spherical, in a shouldered ring moved by a jack pneumatic.
  • the special features of the tool device according to the invention allow to support the efforts that are requested.
  • the support element is carried by a multi-axis robotic arm associated with a mandrel for clamping the tube to be treated mounted on means able to move it along three axes, to a means of heating of the part of the tube to be treated, and to a means management electronics capable of coordinating said movements arm and said means for moving the mandrel so that the axis of said tool, along which the pressure is applied, ie always substantially perpendicular to the surface of said tube, and so as to obtain a relative rotational movement of said tool around a longitudinal axis of said tube, said axis being likely to move.
  • the tube is animated by a movement of pivot around an axis which moves according to an ellipse, that is to say, it describes a movement comparable to that of a crank.
  • the movement is relative, that is to say that either the tube is stationary in rotation and only mobile along three axes, while the arm drives the rotating tool, the tube is animated in axial rotation in association with displacements along three axes.
  • Figure 1 shows a schematic view of a device tool for ogivering and spinning round section tubes and / or ovoid according to the invention.
  • FIG. 2 represents a front view of a tube treated using of the same device.
  • Figure 3a shows a schematic sectional view longitudinal median of a first embodiment of a device of a flow forming tool according to the invention.
  • Figure 3b shows a schematic front view of the same tool device.
  • Figure 4a shows a schematic sectional view longitudinal median of a second embodiment of a flow forming tool device according to the invention
  • Figure 4b shows a schematic front view of the same tool device.
  • FIG 1 one can see a tool device 1 for ogivering and spinning round section tubes and / or ovoid according to the invention, during the treatment of a tube 2, such as that shown in Figure 2 for example.
  • the tube 2 is of cross section ovoid, and the treatment consists in working one of its ends in order to obtain an eccentric narrowing 20 of round section.
  • the tube 2 is held by a mandrel 3 secured to a table three axes 30 able to move the mandrel 3 in the three directions parallel to the longitudinal axis X thereof.
  • the device 1 also includes a means 4 for heating the tube 2, and more particularly from the end thereof is to be treated.
  • the heating means 4 can be of different types, preferably gas or induction.
  • the device 1 includes a flow turning tool 5 carried by a multi-axis robotic arm 50 intended to come into contact with the outer side of the wall of the tube 2.
  • the device according to the invention also comprises a means electronic, not shown, for managing the movements of the three-axis table 30 and multi-axis robotic arm 50 for coordinate these.
  • the device 1 according to the invention can operate according to two possibilities for ogivering or rotating a non-section tube circular.
  • the mandrel 3 animates the tube 2 in an axial rotational movement and it moves on the one hand perpendicular to this axis under the action of table three axes 30 according to a kinematic function of the shape of the tube 2 and of the shape to give it, and on the other hand axially, while the robotic arm 50 remains stationary and orients the tool 5 in depending on the form to give.
  • the tube remains fixed in the mandrel 3 which is movable in displacement along the three axes by through the table 30, while the robotic arm 50 orient the tool and rotate around it an axis parallel to the longitudinal axis of the tube 2.
  • the electronic means of management control the robotic arm 50 so that it is always oriented so that the pressure exerted by the tool 5 is always perpendicular to the wall of the tube 2.
  • Such a device requires a flow-forming tool 5 capable of withstand high pressures and high temperatures.
  • Figures 3a and 3b show a first mode 6 of production of such a flow-forming tool.
  • This tool 6 of which only the active end is shown, comprises a support element 60 pierced with an axial channel 61 of which one end has a narrowing 62 of internal profile in the form of a spherical ring against which comes to bear match a ceramic ball 63 and so that part from it emerges from the support element 60.
  • the ball 63 is held in channel 61 applied against narrowing 62 by a pad 64 made of hard material such as carbo-titanium, having a seat 65 in the form of a congruent spherical cap ball 63.
  • the shoe 64 is itself held in the channel 61 via and a clamping flange 66 and a flange 67 in which the support element is engaged and blocked 60, a ring 68 of elastic material of the elastomer type, engaged between the clamping flange 66 and the shoe 64, serving damping element, which can however be replaced by a spring.
  • the ball 63 can thus roll freely, in all directions, on the surface of the tube to be treated, being guided by the shape of the narrowing 62 and the seat 65 of the shoe 64.
  • the shoe 64 has an axial channel 69 allowing to route to the ball 63, via of a system not shown and through the clamping flange 66 and ring 68, a coolant, air by example.
