Description
Technical field
The present invention relates to carbon slipper field, specifically, relate to a kind of adopting new technology and prepare the method for high-speed train pantograph slide plate carbon slipper.
Background technology
Isostatic pressing technology principle is according to pascal's principle, utilizes goods in the modern technique of each ultra high pressure state compacted under to equalization.Its finished product each to favourable identity, high for performance requriements, the part that complex-shaped and slenderness ratio is large has very good effect.Isostatic pressing technology has the history of more than 70 year, and the initial stage is mainly used in powder metallurgy forming; Over nearly 20 years, isostatic pressing technology has been widely used in the fields such as pottery, casting, nuclear power, plastics, graphite, pottery, permanent magnet, high-voltage electromagnetic porcelain vase, bio-pharmaceutical preparation, food fresh keeping, high performance material, military project.Isostatic pressing technology, by temperature height during shaping and consolidation, is divided into, isostatic cool pressing, warm isostatic pressed, hot isostatic pressing three kinds is dissimilar.Isostatic cool pressing technology (ColdIsostaticPressing is called for short CIP) is at normal temperatures, usually makes thin wall wrap model material with rubber or plastics, take liquid as pressure medium, being mainly used in powder body material shaping, is further sintering, forges to make or hot isostatic pressing operation provides.General use pressure is 100 ~ 630MPa.
China's electric locomotive and bullet train development very fast, electric locomotive railway mileage number more than 120,000 kilometers, and in quick extension.Pantograph pan is the important collecting element that electric locomotive obtains power resources, and slide plate quality is the key factor affecting current carrying quality.Namely pantograph pan is a kind of contact material, is again a kind of Wear-resistant material; Good conductivity and current collection ability should be had, have good comprehensive mechanical performance again.Here the intension of indication slide plate refers to the critical material carbon slipper in slide plate.
Electric locomotive pantograph sliding plate presses materials classification, mainly contains powder shaped charge liner and the large class of carbon element slide plate two.Powder shaped charge liner is divided into iron-based and copper base two class.There is good electroconductibility, but more serious to the wear resistance ratio of railway copper contact line conducting wire.Carbon element slide plate is divided into pure carbon slipper and metal-impregnated carbon slide.Metal-impregnated carbon slide resistance to impact shock is poor, and in addition due to its complex manufacturing, equipment requirements is high, and difficulty is large, and cost is high.
Pure carbon inherently good lubricant, self-lubricating property and Wear vesistance good, carbon slipper is little to contact line conducting wire wearing and tearing, and during slip, electromagnetic noise is little, and high temperature resistant, not easily with contact line conducting wire, weldering phenomenon occurs.Carbon slipper can form one deck carbon film when rubbing with copper contact line conducting wire on wire, significantly improves the abrasion situation of wire.
Pure carbon slipper is in order to reach the monoblock type slide plate of 1250mm length, mainly adopt extrusion process at present, produce the blank of 38 × 38 × 1250mm, the blank that extrusion process is produced is straight shape, and pure carbon slipper physical strength is low, poor impact resistance, running into wire Hard Inclusion in operation easily causes slide plate fracture and break, and work-ing life is low, particularly in rainy season and humid area, ditch is drawn in easy local, often occurs accident between pantograph.
Pantograph pan is generally made up of two portions, and one is directly contact the draw runner (being generally carbon material) born and slide by stream function with osculatory; Another part is the bracket of strengthening draw runner mechanics bearing function.Both must be grouped together by certain assembling process technique, form one and are completely subject to stream unit.Electric locomotive (containing bullet train) the pantograph pan carbon slipper produced both at home and abroad at present, great majority adopt extrusion equipment extrusion forming process to produce the monoblock type slide plate of 1250mm length, all there is certain defect, density of material is low, what have has tiny crack, mechanical strength is poor, and on block of bow collector of electric locomotive, use can exist certain potential safety hazard.
