Abstract
The invention provides a kind of novel electric power pantograph pan of locomotive.Its major technique feature is to have flooded the molten state alloy in the carbon element slide plate, thus improve slide plate anti-folding, compressive strength, increase the service life, all kinds of contact line conducting wires are had good wear, be mainly used in the railway electric locomotive pantograph.
Description
The present invention is used for all kinds of electric locomotive pantograph sliding plates, belongs to the special equipment of electric locomotive traction power plant.
Existing electric locomotive pantograph sliding plate has two kinds on the plain slide plate of pure carbon and partial metallurgy slide plate, and the slide plate bottom surface is the plane.It is good that the plain slide plate of pure carbon reduces mill property to contact line conducting wire, but intensity is low, and property is broken easily broken, and not wear-resisting service life is short; The intensity high abrasion long service life of partial metallurgy slide plate, but big to the contact line conducting wire wearing and tearing, particularly to copper contact line conducting wire serious wear, and self lubricity is poor.
The purpose of this invention is to provide a kind of intensity height, not easily broken broken, the good long service life of resistance to abrasion is to the good novel electric power pantograph pan of locomotive of all kinds of contact line conducting wire anti-attritions.
In order to achieve the above object, the present invention has adopted following measure: stock carbon back bar is made in the mold pressing of carbon element powder, send into the high temperature roasting furnace and be heated to 1200 ℃～1400 ℃ according to certain heating gradient, roast 48 hours is then with carbon back bar vacuumizing; All the other are that the Metal Melting of copper changes into the molten state alloy with 8～18% lead, 4～7 tin, 2～5% titaniums simultaneously, and the carbon back bar of preparation is immersed in the above-mentioned molten state alloy, and inflation is pressurized to (100～150) * 9.8 * 10
4Pa, the carbon back bar is evenly distributed on its inside to keep making the molten state alloy flood in 0.5～1 hour; With the carbon back bar oxygen barrier cooling of impregnated with molten attitude alloy, be processed into the metal-soaked carbon that the bottom surface is the garden deep-slotted chip breaker along its length then, be used for the railway electric locomotive pantograph.
Fig. 1 is a front view of the present invention.
Fig. 2 is a cutaway view of the present invention.
Advantage of the present invention is: anti-folding and compression strength height, self-lubricating and wearability are good. The garden deep-slotted chip breaker is adopted in the slide plate bottom surface, has increased contact line conducting wire and pantograph pan contact friction used thickness partly, prolongation slide plate service life. Good to all kinds of contact line conducting wire anti-attritions, can be widely used in the electric railway section of all kinds of contact line conducting wires.
Embodiments of the invention: carbon element powder heating and mould pressing is become slide plate stock carbon back bar, put into roasting furnace, be heated to 1300 ℃ with 10 ℃ temperature gradient per hour, roast was made slide plate stock carbon back bar in 48 hours.All the other are melting of metal of copper with 15% lead, 5% tin, 4% titanium simultaneously, and its fusing point is at 800 ℃.Air extraction with in the carbon back bar of preparation is immersed in the above-mentioned molten state alloy and puts into autoclave, is forced into 9.8 * 10 thereupon
6Pa is above to be kept 0.5 hour.Take out the slide plate stock oxygen barrier cooling of impregnated with molten attitude alloy, being processed into the bottom surface is garden deep-slotted chip breaker slide plate.The following value made from said method of metal-soaked carbon base performance perameter: apparent porosity 0.5%, rupture strength＞9.8 * 10
7Pa, compressive strength＞25 * 9.8 * 10
6Pa, hardness (HS) is 85～95, electrical resistivity≤5(Ω m).
