Nyob rau hauv xyoo tas los no, nrog rau kev siv ntau ntawm graphite pwm, tus nqi txhua xyoo ntawm cov pwm hauv kev lag luam tshuab yog 5 npaug ntawm tag nrho cov nqi ntawm txhua yam ntawm cov cuab yeej siv tshuab, thiab qhov kub poob loj heev kuj tsis zoo rau lub zog uas twb muaj lawm. -txuag txoj cai nyob rau hauv Suav teb.Qhov loj noj ntawm pwm tsis tsuas yog ncaj qha nce nqi ntawm cov lag luam, tab sis kuj ua rau cov kab ntau lawm shutdowns vim yog nquag hloov pwm, thaum kawg ua rau loj nyiaj txiag poob.
Raws li kev tshawb fawb, vim cov pwm raw cov ntaub ntawv thiab cov nqi zog tau nce siab thiab lwm yam laj thawj, cov khoom lag luam pwm tau txais txiaj ntsig tau poob xyoo tas los; Txhawm rau kom muaj sia nyob thiab txhim kho, ntau lub tuam txhab txais yuav
Cov khoom siv hloov pauv yog siv los ua ib qho kev ntsuas loj ntawm kev hloov pauv thiab kev loj hlob.Nws tau nkag siab tias ntau lub tuam txhab tsim cov khoom siv hluav taws xob graphite, hauv cov pwm tsim tau ua lub luag haujlwm tseem ceeb.Piv nrog cov tsoos tooj liab pwm, cov khoom siv graphite muaj qhov zoo ntawm siab. machining precision thiab zoo nto nyhuv, tshwj xeeb tshaj yog nyob rau hauv cov pwm kab noj hniav ua precision, complex, nyias phab ntsa, siab tawv khoom muaj ib tug zoo kom zoo dua.Piv rau tooj liab, graphite cov khoom muaj qhov zoo xws li tsawg noj, ceev paug ceev, lub teeb yuag thiab me me. thermal expansion coefficient, yog li tooj liab electrode tau maj mam dhau los ua lub ntsiab ntawm cov khoom siv pov tseg.In sib piv, graphite electrode cov ntaub ntawv muaj 6 qhov zoo hauv qab no:
1. Ceev ceev; Lub graphite paug yog 2-3 zaug sai dua tooj liab, thiab cov khoom tsis yooj yim rau deform.Nws muaj qhov pom tseeb zoo hauv kev ua cov txheej txheem nyias nyias electrode.Lub softening point ntawm tooj liab yog nyob ib ncig ntawm 1000 degrees, thiab nws yog ib qho yooj yim rau deform vim tshav kub.
2. Lub teeb yuag; Qhov ceev ntawm graphite tsuas yog 1/5 ntawm cov tooj liab.Thaum cov electrode loj ua tiav los ntawm kev tso tawm, lub nra ntawm lub tshuab cuab yeej (EDM) tuaj yeem txo qis, uas yog qhov tsim nyog rau daim ntawv thov ntawm pwm loj.
3. Cov khib nyiab me me; Raws li cov roj ntsha muaj C atoms, qhov kub thiab txias ua rau C atoms hauv cov roj ntsha kom decomposed thaum lub sij hawm tso tawm, thiab ib zaj duab xis tiv thaiv yog tsim nyob rau saum npoo ntawm graphite electrode, uas compensates rau qhov poob ntawm graphite electrode.
4. Tsis muaj burrs; Tom qab cov tooj liab electrode ua tiav, cov burrs yuav tsum tau muab tshem tawm manually.Txawm li cas los xij, tsis muaj burrs tom qab cov graphite ua tiav, uas tsis tsuas yog txuag tau ntau tus nqi thiab cov neeg ua haujlwm, tab sis kuj ua rau nws yooj yim dua rau kev paub tsis siv neeg ntau lawm.
5. Ib qho yooj yim polishing; Vim hais tias kev txiav tsis kam ntawm graphite tsuas yog 1/5 ntawm cov tooj liab, nws yooj yim dua rau grind thiab polish los ntawm tes.
Vi.Tus nqi qis; Vim qhov nce nqi ntawm tooj liab nyob rau hauv xyoo tas los no, tus nqi ntawm graphite hauv txhua yam yog qis dua li tooj liab.Raws li tib lub ntim ntawm Oriental carbon's universality, tus nqi ntawm cov khoom graphite yog 30% mus rau 60% qis dua. uas ntawm tooj liab, tus nqi yog qhov ruaj khov, thiab lub sij hawm luv luv tus nqi hloov pauv yog me me.Nrog rau kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev ua haujlwm zoo ua qhov tseem ceeb ntawm kev lag luam tsim, graphite electrode cov ntaub ntawv yuav maj mam hloov tooj liab electrode thiab ua si ib qho tseem ceeb. Lub luag haujlwm hauv EDM.Ib yam li ntawd, nyob rau hauv kev sib tw hnyav zuj zus hauv kev lag luam pwm niaj hnub no, kev siv cov cuab yeej ua haujlwm siab heev los tsim cov khoom pwm zoo yog txoj hauv kev zoo tshaj plaws rau cov lag luam kom yeej kev lag luam thiab cov neeg siv khoom.
