Description
Technical field
The utility model belongs to railway switch rail and is coupled technical field, and in particular to a kind of wing rail toe-end structure.
Background technique
Existing movable head track switch wing rail generallys use two kinds of structure types:
One, by after one section of 60AT1 rail localized heat die-forging forming with another section of 60kg/m standard rail flash-butt welding and
At toe-end is by the molding 60kg/m rail profile of 60AT1 rail forging；
Two, using 60TY1 rail, toe-end is machined as 60kg/m rail profile by milling machine, realizes and route 60kg/m
Rail connection.
In the first structure type, flash-butt welding is added using local hot forging, butt weld occurs, structure and plus
Work manufacturing process is complex.
In second of structure type, 60TY1 rail is processed using cold twisting technique, but cold twisting has the wind of cracking
Danger.
Therefore in terms of both the above structure type has structure disadvantage itself and processing technology, urgent need, which is made, to be changed
Into.
We has developed a kind of wing rail toe-end structure and its forming method in order to solve problem above.
Summary of the invention
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of wing rail toe-end structure.
The utility model achieves the above object through the following technical schemes:
A kind of wing rail toe-end structure, including one are successively molding:
Die mould changeover portion rail；
Sectional dimension can contain the profiled section rail of P65 standard rail section.
Wing rail is processed using 60TY1 shaped steel rail, and die mould changeover portion rail and profiled section rail are integrally formed, and ensure that column
Overall height speed crosses the wing rail intensity requirement of trouble.
Specifically, wing rail toe-end structure further includes former material section rail, and former material section rail includes being sequentially connected ground first to fix
Section rail, transition rail and the second fixed section rail；The size and the size phase of 60TY1 rail of first whole section of fixed section rail
Together；The first end of transition rail is identical as the size of the first fixed section rail, the inside rail head of the second end of transition rail
Protrusion part is shorter than the inside rail head of first end, and from the first end of transition rail to second end, inside rail head uniformly shortens length
Degree；The size of second whole section of fixed section rail is identical as the size of the second end of transition rail；
The first end of die mould changeover portion rail is connect with the second fixed section rail, and the size phase with the second fixed section rail
Together, the inside rail head lower end of the second end of die mould changeover portion rail is gradually thinned, and the second end of die mould changeover portion rail is inside
Lateral deviation turns, and from the first end of die mould changeover portion rail to second end, inside rail head lower end is uniformly thinned, and die mould changeover portion rail is equal
It is even to deflect inwardly；
The first end of profiled section rail is connect with the second end of die mould changeover portion rail, whole section of profiled section rail of section ruler
It is very little to contain P65 standard rail section.
To die mould changeover portion rail and profiled section rail different parts, different shape control and selection, so that the track switch wing
The connection smooth transition of rail and section lead curve P65 rail, so that driving is more steady.
Preferably, profiled section rail length is 450mm-600mm；Die mould changeover portion rail length is 150mm-200mm.
The utility model has the beneficial effects that:
1, wing rail is processed using 60TY1 shaped steel rail, and die mould changeover portion rail and profiled section rail are integrally formed, and ensure that
Train high speed crosses the wing rail intensity requirement of trouble.
2, using the integrated molding hot forging moulding process of die mould changeover portion rail and profiled section rail, the track switch wing is solved
The connectivity problem of rail and section lead curve P65 rail makes to be laid on the route of P65 rail using 60TY1 rail type movable head track switch
Wing rail is possibly realized；Meanwhile a kind of brand new form for being different from existing movable head track switch wing rail toe-end is formd, it expands
The application range of 60TY1 rail processing and manufacturing movable head track switch wing rail.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Embodiment 1, as shown in Figure 1 and Figure 2:
A kind of wing rail toe-end structure, including one are successively molding: die mould changeover portion rail 2, sectional dimension can contain P65
The profiled section rail 3 of standard rail section.
Wing rail is processed using 60TY1 shaped steel rail, and die mould changeover portion rail 2 and profiled section rail 3 are one whole rail, nothing
Butt weld.It ensure that train high speed crosses the wing rail intensity requirement of trouble.
Embodiment 2, as shown in figure 1, figure 2, figure 3, figure 4 and figure 5:
The present embodiment the difference from embodiment 1 is that: a kind of wing rail toe-end structure further includes 60TY1 type former material section rail 1,
