Abstract
The invention relates to a steel-aluminum composite contact rail, comprising an aluminum alloy guide rail main body. The steel-aluminum composite contact rail is characterized in that a stainless steel belt is arranged on the working face of the aluminum alloy guide rail main body. Meanwhile, solder layers are distributed at the contact end of the working surface of the stainless steel belt and the aluminum alloy guide rail main body. In a manufacturing process, a containing groove is machined on the working end face of the aluminum alloy guide rail main body; solders are paved in the containing groove to form the solder layer; the stainless steel belt is paved on the solder layer; and the stainless steel belt and the aluminum alloy guide rail main body are mutually combined through high-temperature welding. The steel-aluminum composite contact rail provided by the invention has the advantages of novel and simple structure and lower production cost. Meanwhile, two metals are mutually fused on a metal structure by using a welding technique to remove material contact resistance, so that the contact rail has a good conduction property. The steel-aluminum composite contact rail provided by the invention has a large friction face. Furthermore, the large friction face is an entire stainless steel face, so that electric corrosion is difficult to generate, and the steel-aluminum composite contact rail has high wear resistance and high durability. Furthermore, the effective combination of the stainless steel belt and the aluminum alloy guide rail main body is ensured due to the solder layer.
Description
Technical field
The present invention relates to a kind of rail-engaging and manufacturing approach thereof, relate in particular to a kind of steel-aluminum conductor rail and manufacturing approach thereof.
Background technology
The steel-aluminum conductor rail that urban track traffic is used as electric power system is broadly divided into three types, one type of steel-aluminum conductor rail for mold pressing processing, and complex procedures, efficient is low, and cost is high.Second type is partly wrapped the riveted formula for stainless steel band, and this product has contact surface little, and contact surface is that two kinds of different materials and centre have the slit to be easy to generate problems such as electrocorrosion.The 3rd type is wrapped welded type entirely for stainless steel band; This product has the local organization and the performance that are difficult to weld thicker stainless steel sheet and weld back steel aluminum to change; Shape and surface quality to before compound are all influential; And be difficult to elimination, thereby influence the shortcoming of the total quality of the compound rail of steel aluminium.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of steel-aluminum conductor rail and manufacturing approach thereof are provided.
The object of the invention is realized through following technical scheme:
Steel-aluminum conductor rail includes the aluminum alloy guide rail body, and wherein: the driving surface of described aluminum alloy guide rail body is provided with stainless steel band; The driving surface contact jaw of said stainless steel band and aluminum alloy guide rail body is distributed with solder layer.
Above-mentioned steel-aluminum conductor rail, wherein: the driving surface of described aluminum alloy guide rail body is provided with pockets, and described solder layer is positioned at pockets.
Further, above-mentioned steel-aluminum conductor rail, wherein: described pockets both sides are provided with the circular arc limit.
The manufacturing approach of steel-aluminum conductor rail is characterized in that may further comprise the steps: 1. step processes pockets in the operative end surface of aluminum alloy guide rail body; 2. step lays solder in pockets, constitute solder layer; 3. step lays stainless steel band on solder layer; 4. step adopts high-temperature soldering, makes stainless steel band combine with the aluminum alloy guide rail body.
The advantage of technical scheme of the present invention is mainly reflected in: the present invention is reasonable in design, and novel structure is simple, and productive costs is lower.Simultaneously, welding process merges two kinds of metals on the Golden Elephant structure each other, has eliminated the material resources contact resistance, makes contact rail have the favorable conductive characteristic.And friction face of the present invention is bigger, and is a whole surface stainless steel, is difficult for producing electrocorrosion, wear-resisting more lasting use.Moreover, because the existence of solder layer has guaranteed that stainless steel band combines with the effective of aluminum alloy guide rail body.
Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram of steel-aluminum conductor rail.
The implication of each Reference numeral is following among the figure:
1 aluminum alloy guide rail body, 2 stainless steel bands
3 solder layers, 4 pockets
The specific embodiment
Steel-aluminum conductor rail as shown in Figure 1 includes aluminum alloy guide rail body 1, and its special feature is: the driving surface of the aluminum alloy guide rail body 1 that the present invention adopted is provided with stainless steel band 2.Simultaneously, the driving surface contact jaw in stainless steel band 2 and aluminum alloy guide rail body 1 is distributed with solder layer 3.
With regard to the present invention's one preferred implementation, consider the correct distribution of solder layer 3, also can not influence stainless steel band 2 and combine with the effective of aluminum alloy guide rail body 1, the driving surface of aluminum alloy guide rail body 1 is provided with pockets 4.Thus, can let solder layer 3 be positioned at pockets 4.Like this, in set up procedure, can not occur excessively, can guarantee simultaneously that solder layer 3 distributes to put in place, further guarantee to combine effect.
Moreover, consider that the running of contact rail can be steady, be provided with the circular arc limit in pockets 4 both sides, the burr face of removing parts from occurs.
Further combine actual manufacturing process of the present invention, it roughly may further comprise the steps: at first, and at the operative end surface processing pockets 4 of aluminum alloy guide rail body 1.Afterwards, in pockets 4, lay solder, constitute solder layer 3.Then, on solder layer 3, lay stainless steel band 2.At last, adopt high-temperature soldering, make stainless steel band 2 combine with aluminum alloy guide rail body 1.
In conjunction with actual condition of service of the present invention, the present invention is reasonable in design, and novel structure is simple, and productive costs is lower.Simultaneously, friction face of the present invention is bigger, and is a whole surface stainless steel, is difficult for producing electrocorrosion, wear-resisting more lasting use.Moreover, because the existence of solder layer has guaranteed that stainless steel band combines with the effective of aluminum alloy guide rail body.The more important thing is that welding filler metal combines two kinds of metals on the Golden Elephant structure, eliminated two kinds of resistance that metal produces owing to the material resources contact, thereby made contact rail have the favorable conductive characteristic, reduced the energy loss in the power transmission and transformation to a great extent.
