Abstract
The present invention uses industrial electrolytic copper power or copper alloy powder as substrate, and uses graphite powder as friction reducing agent and makes them undergo the processes of mixing, press-forming, sintering and extruding to obtain the invented pantograph slip board with excellent mechanical physical properties and good antifriction effect.
Description
(1) technical field: metal-base composites scientific domain
(2) background technology: the preparation method of known pantograph pan has following several: 1. pure metal slide plate: such slide plate adopts copper coin or steel plate to make through machining, has physical strength
Height, the convenience of drawing materials, long service life, cost are low, cause the little spy of accident between pantograph obstacle probability
Point, but big to the contact lead abrasion, serious, domestic early stage to copper contact wire abrasion especially
The power locomotive adopts, and existing restriction is used.2. powder metallurgy slide plate, it is that to adopt certain metal-powder be matrix (as iron-based, copper base etc.), adds
Go into multiple metal and non-metallic material, make by technologies such as shaping, sintering.Physical strength
Good, surface hardness is moderate, and the abrasion comparison match of slide plate and lead is because of such slide plate causes
The accident between pantograph probability is very low, has better comprehensive performance.The problem that such slide plate exists is main
The oil length that is slide plate is low, when the lubricant film that forms runs into destruction or lost efficacy, is difficult to form
New lubricant film is kept the good break-in state between slide plate and lead, has so just produced slide plate
To the serious abrasive situation of contact line conducting wire.3. carbon slide plate, carbon itself is exactly good lubricant, and high temperature resistant, and the contact wire of not making peace takes place
The weldering phenomenon, because the improvement of abrasion condition, electric arc and off-line reduce, electromagnetic noise is also little,
But carbon slide plate physical strength is low, and tough is poor, and in service to run into the lead hard spot easy
Cause the slide plate bar to fracture and break, work-ing life, ditch was drawn in low and easy part, particularly rainy season and
The humid area because of frictional force increases, pantograph and catenary fault often occurs.Carbon slide plate resistivity height in addition,
Get when stream static, have the overheated remollescent of the lead of causing may.4. carbon soaks metal slider, and it is that a large amount of pores that will exist in the carbon base body fill up metal, forms practical
Coagulate body, concentrate the advantage of carbon material and metallic substance.Theoretically, be to manage the most at present
The pantograph pan of the copper conductive section of thinking is divided into monoblock type (abroad) and assembly type (domestic)
Two classes have electric property preferably, have solved the low problem of carbon slide plate physical strength substantially,
Wear resisting property greatly improves, and can solve the too fast problem of lead abrasion at all; But this class slide plate
The anti-impact force deficiency is prone to the piece phenomenon, needs shaping in the use, and selling at exorbitant prices,
The maintenance cost height brings bigger economic pressures to maintenance department.
In order to solve above-mentioned pantograph pan deficiency in use, developed the modified version of all kinds of pantograph pans in succession, as, the copper-base powder metallurgy slide plate adds the mechanical combined type copper-base powder metallurgy slide plate that the solid lubricious strip is formed, increase the aluminium-covered carbon slider of carbon bar intensity, carbon fiber reinforced slide plate, carbon fiber reinforced metal base slide plate etc., metal/carbon composite slide-plate etc.The use of these slide plates is because of technology of preparing complexity, production cost height, or use properties can not satisfy requirements such as high speed, heavy lift sliding friction and is restricted.
(3) summary of the invention
The objective of the invention is the deficiency that exists at known technology and a kind of novel method of succeeding in developing, this method is by the control of powder mixes technology, be formed on equally distributed graphite granule in the copper matrix network, then in sintering and extrusion process, further improve the binding ability of matrix and anti-friction composition, thereby obtain mechanical and physical performance excellence, pantograph pan goods that antifriction effect is good, have raw material prepare simple, technological process is controlled easily, pollution-free, production cost is low, can form the characteristics of production in enormous quantities.
The present invention realizes by following technical scheme.
Fig. 1 is a process flow sheet of the present invention.Raw material mixes in mixer after preparing burden, and through behind the cold-press moulding, blank is sent into and carried out sintering in the sintering oven, and the ingot blank behind the sintering send extrusion machine to extrude slab after multiple the pressure again, at last slab is carried out machining, makes the slide plate finished product.The main performance index of slide plate is as shown in table 1.One, material composition and shared weight percent 1. anti-friction compositions thereof:
The crystalline graphite powder, granularity is negative 300 orders, accounts for the 2-10% of gross weight; 2. interpolation element:
