Definitions

  • the present invention relates to a method of forming a flange, which can in particular serve as a stop, on the internal or external wall of a metal tube and, in particular, of a thin tube.
  • the material is made to flow so as to form a circular groove on one side and, consequently, an annular bulge forming a stop on the other side.
  • the flanks of the stops thus produced are inclined relative to the cross section of the tube, which is incompatible with applications requiring free stops.
  • FR-A-1 051 547 has also proposed a process for the manufacture of an external flange on a metal tube, this process consisting, in a first phase, in repressing a tube filled with a repressing material between two dies, the tube being, during this operation, hermetically closed at its two ends and retained externally on all sides, except at the location of the flange to be formed, then, in a second phase, after having removed the filling material, to compress the bulge formed during the first phase between the two matrices.
  • This process is relatively complex, due to the use, in one of the phases, of a filling material, and the use of dies. In addition, it does not allow an internal collar to be produced.
  • the present invention aims to remedy these drawbacks by making it possible to obtain flanges constituting frank stops, both on the internal face and on the external face of metal tubes, by simple deformation of the metal.
  • a method of forming a flange on the wall of a tube preferably of small thickness, this method being characterized in that, the tube being empty of any filling, we form, in a manner known per se, by a metal pushing operation, such as knurling, at the periphery of the tube and on the face opposite to that where it is desired to obtain the flange, a circular groove limited by two adjacent flanks, and in which is then exerted on the ends of the tube axial compression, until bringing into contact the two adjacent flanks formed during the first phase.
  • a metal pushing operation such as knurling
  • US Pat. No. 3,031,904 describes a tool capable of being engaged inside a tube with a view to imparting a deformation which results in the formation of an annular groove on the outside of this tube.
  • the method according to the invention is limited to the combination of a preliminary phase of deformation of a tube capable of producing on this tube an external or internal groove and of an axial compression phase subsequent of said tube exerted on its two ends, with a view to bringing the two sides of said groove into contact.
  • the invention does not encompass each of these phases, considered in isolation.
  • the method according to the invention has the advantage of providing flanges whose planes are substantially perpendicular to the wall of the tube. They thus constitute frank stops, capable of constituting a non-deformable blocking means.
  • Another advantage of the invention resides in the fact that in the case of an internal stop, the usual external groove, which attracted the eye, is replaced by a simple circular line.
  • annular groove is formed on a tube 1.
  • an axial compression force shown by arrows 9 and 10 is applied to the tube.
  • This force must be sufficient to bring the two sides 7 and 8 of the groove 6 into contact.
  • the flange 11 formed by the sides 7 and 8 is substantially located in a cross section of the tube and, therefore, constitutes a frank and non-deformable stop.
  • Figures 4, 5 and 6 show an alternative embodiment of the invention in which the flange is formed not inside the tube, but outside of the latter.
  • An advantageous implementation of the method according to the invention consists, during the first deformation phase and as shown in FIG. 7, in pushing the bottom 15 of the circular groove 17 until it is in the alignment of the wall 19 (alignment shown by the line 1-1) on which the flange will be formed.
