Definitions

  • the invention relates to a transition rail for the connection of rails with mutually different rail cross section and to a method for producing such a transition rail.
  • the transition piece is formed so that all parameters to be changed are changed substantially simultaneously and over the same length of the transition rail piece both an adjustment of the height of the web and the rail foot was made.
  • a transition from one rail profile to the other rail profile should be ensured here on the shortest possible length.
  • the EP 1 013 826 is still based on the conviction that in the area of the transition from a rail profile to another rail profile a substantially continuous geometry is to be achieved, with appropriate adjustments in a connection-side end should be made.
  • a transition rail has become known over the entire length of which the rail foot width is adapted from a first connected rail with a wider rail foot to a further connected rail with a narrower rail foot.
  • a transition region is provided, in which the transition from the larger rail profile height of one rail to the lower rail profile height of the other rail takes place.
  • transition rail From DE-C-617 016 a transition rail has become known, wherein the web of the lighter profile is split to accommodate the height dimensions, and spatially separated therefrom, the foot and head width of the stronger profile is reduced to adjust the width dimensions.
  • the invention now aims to provide a transition rail of the type mentioned, with which it is possible to connect rails with mutually different rail sections and rail profiles with each other, which also allows higher wheel loads without local overload and voltage peaks and therefore formed to a greater extent unbreakable is as previously known transition rails.
  • the transition rail on two transition areas wherein in a first transition region, only the cross-sectional profile with the greater height is transformed into a lower profile height and processed in the subsequent second, the lower profile height, transition region only the rail in adaptation to the new profile of the subsequent rail foot.
  • the invention thus proposes to separately make the necessary adjustments in spatially separated transition areas and to reduce only the profile height in a first sub-area and only in a spatially separate further sub-range to adapt the rail to the new profile.
  • a reduction in the profile height as is done in a particularly simple manner by upsetting or pressing, has naturally results in other dimensions and in particular the width of the foot increasing with corresponding lateral pressing force to the web in this subregion.
  • a further preferred embodiment results when the second transition region, which already has the lower profile height and whose rail foot is machined in adaptation to the new profile of the adjoining rail foot, is arranged closer to the free end of the transition rail than the first transition region.
  • the second, only mechanically machined transition region of the weld is closer, stress concentrations, as in the first case, by deformation formed transition area, occur, can be kept away from the weld.
  • the inventive method for producing such a transition rail is essentially characterized in that the transition rail is first heated and introduced into a mold, whereupon the rail is deformed in the web area and pressed in the profile height direction and that is mechanically processed after the complete transformation of the rail ,
  • the fact that in a first process step after heating only a pressing, it is possible to deform the transition rail to the desired profile height, thereby bringing the web width is brought to the desired level or on the desired that a mold is used Measurements can be kept. Only after such a complete transformation, which naturally extends over a certain axial length of the transition rail, the second adjustment is made, with subsequently the rail foot is machined.
  • the rail foot is subsequently machined, whereby it is simultaneously possible to make the transition from a wider to a narrower rail foot with a corresponding rounding while maintaining defined radii.
  • the training is such that the transition region of the rail foot, in which the width of the rail foot increases or decreases, rounded in plan view, whereby the risk of cracks in this transition region is further reduced.
  • the invention makes it possible to form corresponding transition rail pieces separately from both rails, wherein such a transition piece can be connected in a particularly simple manner by means of flash butt welding with a connecting rail piece with the changed rail profile, so that in the sequence of installation in the track is further simplified and further welding operations no longer affect the area of the transition rail.
  • Fig.1 a side view of a rail track with built transition piece
  • Fig.2 a plan view of the illustration after Fig.1, Fig.3 a section along the line III / III of Fig.1, Fig.4 a section along the line IV / IV of Fig.1 and Fig.5 a section along the line V / V of Fig.1 ,
  • Fig.1 1 denotes a transition rail, which, starting from a standard rail profile 2, enables a transition to a further rail profile 3.
  • the transition rail 1 is connected to the control rail with a modified profile height 3 by means of welding, wherein the corresponding weld is denoted by 4.
  • the area b is in the training after Fig.1 and 2 formed as a substantially neutral area in which the rail foot has not yet been processed in its width and only the profile height has been adapted by Umschmieden or pressing to the new conditions.
  • this forging or pressing operation in which, as can be seen in particular from the cross sections of the 3, 4 and 5 results, at the same time pressing forces in the height direction and transverse to the bridge are used.
  • Figure 3 is the final connection profile with the changed rail height and the changed web width, which corresponds to the rail section 3, can be seen.
  • This the section according to line III / III of the Fig.1 corresponding profile shape thus corresponds to the profile which can be welded to the transition rail.
  • the section IV / IV was laid, which in Figure 4 is shown.
  • the output profile according to the rail 2 is characterized by much wider rail webs and larger profile height. This initial profile corresponds to the section on the line V / V and is in Figure 5 seen.
