Abstract
The utility model relates to a current collector slide plate for electric locomotives, which belongs to a special body for current collector friction flow equipment of electric locomotives. A slide plate is in a combined type and is divided into an upper layer and a lower layer, wherein, the upper layer is solid lubricant; the lower layer is alloy with high strength and high tenacity; the upper layer is infiltrated and combined with the lower layer; a sliding surface of the upper layer contacted with a conducting wire is in an arc shape; the solid lubricant is composed of composite materials of graphite, tin, etc.; the alloy is manufactured by metallurgy of iron copper base powders. The combined metal infiltrated slide plate has the advantages of good self lubricating ability, abrasive resistance, stretching resistance, folding resistance, shock resistance and small resistance coefficient. The utility model is suitable for various types of conducting wire electrification railway sections.
Description
The utility model relates to the special-purpose body that flow device is got in the block of bow collector of electric locomotive friction, is used for all types of electric locomotive pantograph sliding plates.
Existing electric locomotive uses carbon slide plate and partial metallurgy slide plate two big classes.Merits and demerits is respectively arranged, and the carbon slide plate is little to lead abrasion, but the low poor toughness of intensity, resistance is big, and is frangible not shock-resistant, not wear-resisting, and service life is short; The intensity height of partial metallurgy slide plate, shock-resistant, compare service life high, but its lubricity is poor, big to the lead wearing and tearing, shortening lead service life.
The purpose of this utility model is the shortcoming that overcomes carbon slide plate and partial metallurgy slide plate, provides a kind of wear-resisting lubricity again strong, and is good to all kinds of lead anti-attritions, the intensity height, good toughness, shock-resistant, not easily broken broken, resistance is little, and the NEW TYPE OF COMPOSITE of long service life is soaked the metal power pantograph pan of locomotive.
The technical solution of the utility model is achieved in that compound its special character of metal slider that soaks of a kind of block of bow collector of electric locomotive is that slide plate is a combined type, be divided into two-layer up and down, the upper strata is a solid lubricant, lower floor is the good alloy of strength high toughness, two-layer up and down infiltration combines, and the sliding surface that the upper strata contacts with lead is the garden camber.Scheme solid lubricant at the middle and upper levels is made up of composite materials such as graphite, tin, and the alloy that the high tenacity of lower floor is good adopts iron tinbase partial metallurgy to manufacture.
Major advantage of the present utility model is: self-lubricity and resistance to abrasion are good, tension and rupture strength height, and impact resistance is good, and resistance coefficient is little.The sliding surface that the slide plate upper strata contacts with lead is the garden camber, has avoided scraping lead, has prolonged the service life of slide plate and lead, and is good to all kinds of contact wire anti-attritions, can be widely used in the electric railway section of various contact line conducting wires.
Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail:
Fig. 1 is the compound metal slider front view that soaks of block of bow collector of electric locomotive
Fig. 2 is the compound metal slider cutaway view that soaks of block of bow collector of electric locomotive
Among the figure: 1, upper strata solid lubricant
2, lower floor's high-ductility alloy
3, fixing threaded hole
In order to achieve the above object, the utility model has adopted following technical proposals:
Earlier that strength high toughness is good copper fe-based alloy powder filling mould lower floor, the tin alloy powder that layer overlay is very thin equably then, last again the composite powder filling of slide plates such as graphite being put in place suppressed, obtain the composite slide-plate pressed compact and pass through high temperature sintering again, be heated to temperature below the matrix constituent element fusing point by certain heating gradient, (1000～1120 ℃) be absolute fusing point 0.7-0.8 doubly.Be incubated under this temperature, in the sintering process, metal powder granulates inside begins to process crystallization again and collective recrystallization, and two parts up and down of slide plate under the effect of metallic intermediate layer infiltration technology, are combined as a whole securely.Separation phenomenon under intense impact and under the state that expands with heat and contract with cold, can not take place in this complex matrix that is combined into one through the mutual infiltration of high temperature multi-element metal yet, behind the sintering, through the oxygen barrier cooling, then, upper surface is processed into the garden camber, and final immersion oil is made compound type and is soaked metal slider.
The compound type that produces with above-mentioned technological process soaks metal slider, and its main technical characteristics is as follows:
Resistance coefficient＜30 μ Ω cm.
Proportion: 7.6～8.28g/cm
3
Superficial hardness: HB50～70
Tensile strength〉140N/mm
2
Bending strength〉290N/mm
2
Impact value〉10Nm/cm
2
Bitumen content〉10%
Metallographic structure: top is polynary soft metal composition, contains a large amount of solid lubricants, and the middle part, is combined as a whole two parts with molten mutually up and down securely by the infiltration metal, and the bottom is fine and close alloy substrate.
Claims (2)
1, a kind of electric locomotive pantograph sliding plate is characterized in that slide plate is two-layer about combined type is divided into, and the upper strata is a solid lubricant, and lower floor is the good alloy of strength high toughness, and two-layer up and down infiltration combines, and the sliding surface that the upper strata contacts with lead is a circular arc type.
2, slide plate according to claim 1 is characterized in that the solid lubricant on upper strata is made up of composite materials such as graphite, tin, and the alloy that the high tenacity of lower floor is good adopts the iron copper-base powder metallurgy to manufacture.
