Abstract
The invention designs a graphite processing device, and in particular relates to an extrusion-molding die for manufacturing graphite strips. The extrusion-molding die for manufacturing graphite strips includes an upper die, a lower die, a sliding rod and a die cavity, wherein the upper die and the lower die are relatively arranged; the sliding rod is perpendicularly arranged on the edge of the lower die and the upper die can slide up and down along the sliding rod; the die cavity is formed in the lower die; and a cooling device is arranged in the lower die. The extrusion-molding die for manufacturing graphite strips disclosed by the invention can effectively manufacture and shape graphite strip-shaped parts and can prevent a graphite material from becoming deformed in an extrusion process. By virtue of the cooling equipment arranged in the die cavity, the cooling efficiency is improved, so that the graphite strips can remove from the die cavity smoothly and the integrity of the graphite strips is guaranteed.
Description
Technical field
The present invention designs a kind of machining graphite device, particularly relates to a kind of extruded mould for making graphite bar.
Background technology
Carbon is a kind of very common element, and it is extensively present among air and the earth's crust in a variety of forms.Carbon simple substance very early by people's knowledge and utility, a series of compounds of carbon---organic matter life especially basic.Carbon is one of composition of the pig iron, wrought iron and steel.Carbon can chemically oneself combine and form large quantization compound, on biology and commercial be important molecule.In organism, most of molecule all contains carbon.
Graphite has good chemical stability.Through the graphite of special processing, there is the features such as corrosion-resistant, thermal conductivity good, and permeability is low, just a large amount of for making heat exchanger, reactive tank, condensed device, combustion tower, absorption tower, cooler, heater, filter, pumping unit.Be widely used in the industrial departments such as petrochemical industry, hydrometallurgy, soda acid production, synthetic fibers, papermaking, a large amount of metal materials can be saved.
The kind of impermeable graphite is because of resinous difference, and corrosion resistance is also variant.As resin impregnating, person is acidproof, but not alkaline-resisting; Furfuryl alcohol resin dipper is both acidproof, alkaline-resisting again.The heat resistance of different cultivars is also variant: carbon and graphite can be resistance to 2000 ~ 3000 DEG C in reducing atmosphere, in oxidizing atmosphere, start oxidation respectively 350 DEG C and 400 DEG C; Impermeable graphite kind is different with impregnating agent, generally by phenolic aldehyde or furfuryl alcohol dipper heat-resisting below 180 DEG C.
Cast, founding, pressing mold and pyrometallurgy material: because the thermal coefficient of expansion of graphite is little, and the change of ability rapid heat cycle, can be used as the mold of vierics, ferrous metal after graphite is used to obtain casting dimension accurate, any surface finish yield rate is high, just can use without processing or slightly doing processing, thus save a large amount of metal.Produce the powder metallurgical techniques such as carbide alloy, usually make the porcelain boat of pressing mold and sintering with graphite material.The crystal growing crucible of monocrystalline silicon, zone refining container, stent holder, induction heater etc. all process with high purity graphite.In addition graphite also can make graphite thermal insulation board and the base of vacuum metling, high temperature resistance furnace boiler tube, the elements such as rod, plate, lattice canopy.
The convenient transport of graphite bar and processing, graphite raw material all transports as graphite bar by all kinds of production enterprise, but graphite bar is more complicated in process, and and mould between disengaging step very complicated, existing mould adopts outside direct intervention to be depart from, the graphite of its mould inside can not obtain little cooling like this, causes graphite bar to depart from unsuccessfully.
Summary of the invention
The present invention is directed to above-mentioned deficiency and provide a kind of extruded mould for making graphite bar.
The present invention adopts following technical scheme:
Extruded mould for making graphite bar of the present invention, comprises mold, bed die, sliding bar, die cavity; Described mold and bed die positioned opposite, the edge of bed die is arranged vertically sliding bar, and mold slides up and down along sliding bar; Die cavity is provided with in bed die; Cooling device is provided with in bed die.
Extruded mould for making graphite bar of the present invention, described die cavity is provided with several, and several die cavitys are arranged parallel to each other.
Extruded mould for making graphite bar of the present invention, is provided with cooling tube between described each die cavity.
Extruded mould for making graphite bar of the present invention, described cooling tube outer wall is provided with conductive sheet.
Extruded mould for making graphite bar of the present invention, described conductive sheet extends to die cavity outer wall.
Extruded mould for making graphite bar of the present invention, described cooling tube center is provided with barrier sheet.
Extruded mould for making graphite bar of the present invention, one end of described cooling tube is provided with inlet, the other end is provided with outlet end.
Beneficial effect
Extruded mould for making graphite bar provided by the invention, effectively can make shaping graphite bar shape parts, can not cause the distortion of graphite material in extrusion process.Arrange cooling device in its die cavity and improve cooling effectiveness, the graphite bar being departs from smoothly from die cavity, ensure that the integrality of graphite bar.
Be provided with barrier sheet in cooling tube in die cavity, prevent cooling fluid from refluxing, provide cooling effectiveness.
