Description
Technical field
The present invention relates to a kind of manufacture method of the compound slider bed platen of track turnout, particularly a kind of track turnout slider bed platform
The bedplate surface complex method of plate.
Background technology
Slider bed platen is the vitals in railway switch product.
Slider bed platen is square groove shape, and fin is connected between the both sides trough rim in bottom land, and there is low trough rim section at slider bed platen two ends,
There is U-shaped recess on the bottom land of low trough rim section, the lateral surface of slider bed platen bottom land is the bedplate surface of slider bed platen.
Track turnout product is arranged on the line infall of railroad track two, after installation, the notch of slider bed platen downwards, bedplate surface
Upward, it is against on bedplate surface below track turnout tongue, slider bed platen is both the plane that support movable tongue level is slided,
The platform of tongue held stationary when being to ensure that train passes through again.From the point of view of from the installation site of slider bed platen and using function, slider bed
Platen requires there is higher mechanical strength, and bedplate surface is difficult to get rusty and erosion resistant.
The multiplex carbon steel material forging of slider bed platen, casting or the method welded are made.Although the slider bed platen intensity of carbon steel
It is higher, but bedplate surface gets rusty easily, and wear-corrosion resistance is poor.
In order to make the intensity of slider bed platen high, bedplate surface erosion resistant, non-corrosive.Chinese patent document CN 102453842A
In disclose the slider bed platen that a kind of use special alloy martensitic stain less steel makes.Though this slider bed platen intensity is higher but cost
Also higher, comprehensive Jing skills index is unreasonable.
In order to improve the comprehensive Jing skills index of slider bed platen, in Chinese patent document CN 103741562A one kind is disclosed
Compound slider bed platen, the preparation method of the compound slider bed platen is：The slider bed platen blank of carbon steel is taken, then in slider bed platen blank
The martensitic stain less steel composite bed containing Cr >=11.5% is combined with the method for built-up welding on bedplate surface.This compound slider bed platen is to use
The method of built-up welding is combined the martensitic stain less steel composite bed containing Cr >=11.5% on the bedplate surface of slider bed platen blank, during making
Low production efficiency, made by be combined slider bed platen composite bed uneven.
The content of the invention
The invention aims to overcome above-mentioned deficiency, propose that production efficiency is high during a kind of making, made by be combined and slide
The manufacture method that table plate composite bed is uniformly combined slider bed platen.
The present invention is achieved using the following method.
The scheme of the invention of this compound slider bed platen is multiple on the bedplate surface of slider bed platen blank with the method for Explosion composite
Martensitic stain less steel composite bed of the unification layer containing Cr >=11.5%.
To realize foregoing invention scheme, the manufacture method of compound slider bed platen has the following steps：
1. slider bed platen blank and the martensitic stainless steel containing Cr >=11.5% that m × n carbon steel material makes, institute are taken
The slider bed platen blank stated is square groove shape, and fin is connected between the both sides trough rim in slider bed platen bottom land, and slider bed platen two ends have
Low trough rim section, is connected with respectively fin between the both sides trough rim of low trough rim section outer end, the lateral surface of slider bed platen blank bottom land is sliding
The bedplate surface of table plate blank material, above-mentioned m and n is 2～30 natural number；
2. cement, sand and water are taken, cement concrete is produced；
3. the concrete flat slab of rectangle is made with cement concrete；
4. the fill concrete in the groove of slider bed platen blank；
5. m × n slider bed platen blank notch of fill concrete in groove is closely aligned successively downwards and is placed in square
In the plate face of the concrete flat slab of shape, allow m × n square groove shape slider bed platen bedplate surface at grade, obtain combine bottom
Plate；
6. the martensitic stainless steel containing Cr >=11.5% is compounded in the platen of combination base plate with the method for Explosion composite
On face, obtain being separated because of blast m × n is compounded with the horse containing Cr >=11.5% on the bedplate surface of slider bed platen blank
The monoblock of family name's body corrosion resistant plate；
7. concrete, burr and the shaping of monoblock are removed, compound slider bed platen blank is obtained；
8. the compound slider bed platen blank of machining, makes up to the shape and size of design, obtains compound slider bed platen.
The bedplate surface area of single slider bed platen blank is less, it is difficult to the method for Explosion composite containing Cr >=11.5%
Martensitic stainless steel is compounded on the bedplate surface of single square groove shape slider bed platen blank；Slider bed platen blank is square groove shape, is used
Square groove shape slider bed platen base when the method for Explosion composite is compounded in the martensitic stainless steel containing Cr >=11.5% on bedplate surface
Material can occur larger deformation.
The present invention is filled in the groove of slider bed platen blank, filling concrete concrete in m × n groove with cement concrete
Down the row of being arranged in order is placed in the plate face of the concrete flat slab of rectangle slider bed platen blank notch；Slider bed platen two ends are low
Fin is connected between the both sides trough rim of trough rim section outer end, the method for not easy-to-use Explosion composite is overcome in single square groove shape slider bed platform
Plate blank material is combined the martensitic stainless steel containing Cr >=11.5% and Explosion composite square groove shape slider bed platen blank can occur it is larger
Deformation a difficult problem.Make that compound slider bed platen production efficiency when making is higher, the composite bed for making compound slider bed platen is very equal
It is even.
After Explosion composite, the strong impact power produced because of blast is compounded with the geneva containing Cr >=11.5% m × n
The slider bed platen blank of body corrosion resistant plate is separated into m × n monoblock.What minority was connected individually is compounded with containing Cr >=11.5%
The slider bed platen blank of martensitic stainless steel, the method that can be machined into is separated.
Below in conjunction with the accompanying drawings, the present invention is further described.
