Definitions

  • the section of railway rails is generally a function of rail traffic. Consequently and to ensure the continuity of the track, a transition sector is required to ensure the connection between rails of different sections.
  • One of these means consists in aligning, end to end, two rails of different sections and making the connection between these rails using joint bars.
  • These fishplates consist of machined or forged bars, adapted to the profile of each of the two rails and which are bolted to each of these, laterally between the head and the foot of the rail so that the rolling edges of each of the two rails are in mutual alignment.
  • Another means of producing these transition sectors uses composite parts called "mixed coupons".
  • This process consists in folding down one end of a section of rail with a large section, after having heated it, to reduce its height to that of the rail with a small section.
  • the excess material which thus accumulates in the core of the rail is then removed by machining in order to adapt the section of this rail to that of the rail of small section.
  • the section shaped in this way is then welded, at the factory, to a section of small section to form a mixed coupon having ends of small section respectively of large section.
  • This process cannot be applied in the factory on standard length rails, for example 18 meters, because the handling and transport of a mixed coupon with a length of 36 meters is very difficult.
  • the invention provides a method of manufacturing a transition sector of a railroad rail to ensure the connection between rails of different sections, which is characterized in that one reduces, by forging , the end of a rail having the largest section up to the section of the rail having the smallest section and in that this sector is welded, on site, between the rails of different sections.
  • the invention therefore allows the elimination of the weld between two ends of different sections. This not only eliminates the costs and hazards of a weld, but also makes it possible to maintain the fibers of the steel and, consequently, to preserve the mechanical properties of the rail.
  • a rail 10 whose section must be reduced is uniformly heated to red by means known per se and not shown.
  • This rail 10 is then turned over in a fixed elongated cradle 12 of a forging press, so that its head 15 is housed in the cradle 12 as shown in FIG. 1.
  • Suitable means, not shown, are provided at the end of rail to hold it in the position shown.
  • two dies 14 On either side of the rail 10 are provided two dies 14 which can slide, in a coordinated manner, transversely with respect to the rail 10 under the action of hydraulic means not shown. These dies each have a buffer 16 for deformation of the rail 12.
  • these buffers 16 are variable in the longitudinal direction, that is to say perpendicular to the plane of Figures 1 and 2, so that the section corresponds on one side to that of the rail having the smallest section (see fig.2) and, on the other side, to that of the rail having the strongest section (see fig.1), the evolution of the section of each pad 16 between these two ends being progressive.
  • the press is closed by displacement of the dies 14 towards the rail 10, the latter undergoes progressive deformation over the length of the pads 16 between the high section and the low section.
  • the excess material is essentially forced back into the base 18 of the rail so that the latter becomes thicker (see FIG. 2) while a flange 16a on the dies 16 prevents its widening or reduces its width .
  • this rim 16a is maximum on one side (fig.2) and minimal or even absent on the other (fig.1) with a progressive evolution from one side to the other.
  • the forging operation described above is not carried out at the end of the rail, it is possible to have it followed by one or more complementary forging operations, this time using another set of dies whose buffers have, on the entire length, a uniform section complementary to that of the rail of small section.
