Description
Technical field
The present invention relates to a kind of conductor rail and its manufacture method.
Background technology
Steel-aluminium composite conducting rail is typically to be composited by bimetallic material, i.e. aluminium section bar body and abrasion resistant coating.Steel aluminium
Composite conducting rail has diversified forms release at present, wherein as I-shaped rail and C-shaped-track have been widely used in subway, the rail such as single track
Road traffic electric power system, mining, metallurgy, harbour, main facilities, the mobile electric power system of equipment used in recreation ground also have compared with
Many application cases.
Chinese patent ZL998118370, ZL2007100492487 and ZL2007101455907 disclose a kind of conduction
Rail and its manufacture method, the brush face that it is connected by a matrix and one with the matrix and is made up of a kind of more resistant material
Composition, is provided with the lath or convex stretched along the length direction in brush face on the part formed towards matrix side in brush face
Rise, wherein each lath or the raised long and narrow side in a longitudinal direction with brush face part are collectively forming a recess, by the material of matrix
Material filling.The two difference is in the pattern difference in complex method difference and brush face section bar.
French Patent (FRP) FR2286680A1 discloses a kind of conductor rail and its manufacture method, and this conductor rail is by an aluminium
Matrix and one are connected with aluminum substrate and by a kind of more resistant stainless steel band（Brush face）Composition, steel band upper surface passes through roll-in
Obtain and smooth award flow table face.Stainless steel band has the deformation on along its length and is pressed into aluminum substrate, and its edge inserts aluminium base
Locked by concora crush roller or crease roller in groove on body, the deformation on length direction is continuous V-shaped groove.
The brush face section bar production of wherein first, second and third kind embodiment has diversified forms：Extruding；Rolling-drawing
Pull out or milling process, these technical process are cumbersome, quality control difficulty is larger, and production cost is higher, rectified in addition in view of required
Directly, the intermediate processing steps such as pickling, cost is very high on the whole and complexity for the manufacture method of brush face section bar.
4th kind of embodiment its combination process only has to be deformed at two：1st, there is steel band waist continuous V-shaped groove to deform and press
Enter aluminium section bar；2nd, steel band edge is inserted in the groove of aluminium section bar, and aluminium section bar cell wall pins steel band by concora crush roller or corrugation roll press
Edge.The important faying face of this complex method is plane or almost plane, therefore its bond strength is not high, under arms process
In steel band stress skewness is caused due to temperature change and abrasion, ablation, the possibility that steel aluminium is disengaged is larger；Add compound
During work, because the extension speed of top and waist steel band is difficult to control to, steel band can not be compound with matrix material well, because
Steam, dust in this Service Environment etc. will enter the two faying face, cause the generation of electrochemical corrosion.
