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 one of the ⁇ - like transition rail.
EP 1 013 826 is also based on the conviction that in the area of the transition from a rail profile to a further rail profile, an essentially steady course of the geometry is to be achieved, with corresponding adjustments being made in an end region on the connection side.
the invention now aims to provide a transition rail of the type mentioned at the outset, with which it is possible to connect rails with different rail cross sections and rail profiles to one another, which also allows higher wheel loads without local overloading and voltage peaks and is therefore designed to be more break-resistant is as previously known transition rails.
the transition rail according to the invention is essentially characterized in that the transition rail has two transition regions, the cross-sectional profile with the greater height being transformed into a lower profile height in a first transition region, and in the subsequent second transition region having the lower profile height the rail base is machined to match the new profile of the subsequent rail base.
a neutral intermediate region that is to say a region with a constant cross-sectional shape, can preferably also be provided between the two sub-ranges, which are adapted to the new geometry, so that a further reduction in the stress concentration can be achieved between the two deformation zones.
a further preferred embodiment results when the second transition area, which already has the lower profile height and whose rail base is machined to match the new profile of the adjoining rail base, is arranged closer to the free end of the transition rail than the first transition area.
the welding is carried out with the connection rail which has the lower profile height and the modified rail base, whereby the fact that the second, only mechanically machined transition region is arranged closer to the welding point results in stress concentrations, as may be the case in the first Around- Formation formed transition area occur from the welding ⁇ can be kept away.
the process according to the invention for the production of such a transition rail is essentially characterized in that the transition rail is first heated and introduced into a press mold, whereupon the rail is formed in the web area and pressed in the profile height direction and that after the complete forming the rail foot is machined.
a press mold As a result of the fact that in a first process step only a pressing takes place after heating, it is possible to deform the transition rail to the desired profile height, and by using a pressing mold, the web width is also brought to the desired dimension or can be kept at the desired level. Only after such a complete reshaping, which naturally extends over a certain axial length of the transition rail, is the second adjustment carried out, the rail base then being machined.
the rail base is subsequently machined, which at the same time makes it possible to transition from a wider to a narrower rail base with a corresponding rounding while observing defined radii.
the design is advantageously such that the transition area of the rail foot, in which the width of the rail foot increases or decreases, is rounded in plan view, as a result of which the risk of cracks in this transition area is further reduced.
the invention allows corresponding transition rail pieces to be formed separately from the two rails, such a transition piece being able to be connected in the factory in a particularly simple manner by means of flash butt welding with a connecting rail piece to the changed rail profile, so that the installation in the track is further simplified and further welding processes no longer affect the area of the transition rail.
FIG. 1 shows a side view of a rail run with a built-in transition piece
FIG. 2 shows a top view of the illustration according to FIG. 1
FIG. 3 shows a section along the line III / III of FIG. 1
FIG Section along the line IV / IV of Fig.l and Fig.5 a section along the line V / V of Fig.l.
Fig.l 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, the corresponding weld seam being designated by 4.
region b is designed as an essentially neutral region, in which the width of the rail base has not yet been processed and only the profile height has been adapted to the new conditions by forging or pressing.
this forging or pressing process takes place, in which, as can be seen in particular from the cross sections according to FIGS. 3, 4 and 5, pressing forces in the vertical direction and transversely to the web are simultaneously used.
FIG. 3 shows the " final connection profile with the modified rail height and the modified web width, which corresponds to the rail section 3.
This profile shape corresponding to the section along line III / III of FIG. 1 thus corresponds to the profile which is associated with the transition rail Section IV / IV, which is shown in Fig. 4, was made in the area of the transition rail itself.
This representation shows that only the rail foot is different from its nominal width and must subsequently be removed by machining to the nominal width.
the starting profile corresponding to rail 2 is characterized by considerably wider rail webs and a larger profile height. This initial profile corresponds to the section along the line V / V and can be seen in Fig. 5.
