Daim ntawv thov ntawm graphite electrode hauv kev tsim pwm

1.EDM cov yam ntxwv ntawm cov ntaub ntawv graphite.

1.1. Kev ua haujlwm ceev.

Graphite yog cov khoom siv tsis yog hlau uas muaj qhov kub siab heev ntawm 3,650 ° C, thaum tooj liab muaj qhov kub ntawm 1,083 ° C, yog li cov graphite electrode tuaj yeem tiv taus cov xwm txheej teeb tsa tam sim no ntau dua.
Thaum thaj chaw tso tawm thiab qhov loj ntawm qhov loj ntawm electrode loj dua, qhov zoo ntawm kev ua haujlwm siab ntawm cov khoom siv graphite yog qhov pom tseeb dua.
Qhov thermal conductivity ntawm graphite yog 1/3 ntawm tooj liab, thiab cov cua sov tsim tawm thaum lub sijhawm tso tawm tuaj yeem siv los tshem tawm cov khoom siv hlau kom zoo dua. Yog li ntawd, qhov ua tau zoo ntawm graphite yog siab dua li ntawm tooj liab electrode hauv kev ua haujlwm nruab nrab thiab zoo.
Raws li kev paub txog kev ua haujlwm, qhov ceev ntawm cov txheej txheem tawm ntawm graphite electrode yog 1.5 ~ 2 npaug sai dua li ntawm tooj liab electrode nyob rau hauv cov xwm txheej siv kom raug.

1.2. Kev siv hluav taws xob.

Cov graphite electrode muaj tus cwj pwm uas tuaj yeem tiv taus cov xwm txheej tam sim no siab, ntxiv rau, nyob rau hauv qhov xwm txheej ntawm qhov chaw roughing tsim nyog, suav nrog cov khoom ua haujlwm carbon steel tsim tawm thaum lub sijhawm machining tshem tawm cov ntsiab lus thiab cov kua ua haujlwm ntawm qhov kub siab decomposition ntawm cov pa roj carbon particles, qhov polarity nyhuv, nyob rau hauv qhov kev ua ntawm ib feem tshem tawm cov ntsiab lus, cov pa roj carbon particles yuav lo rau ntawm qhov chaw electrode los tsim ib txheej tiv thaiv, xyuas kom meej tias cov graphite electrode hauv kev poob me me hauv kev ua haujlwm ntxhib, lossis txawm tias "zero pov tseg".
Qhov poob ntawm electrode tseem ceeb hauv EDM yog los ntawm kev ua haujlwm tsis zoo. Txawm hais tias qhov poob siab yog siab hauv qhov chaw teeb tsa ntawm kev ua tiav, qhov poob tag nrho kuj qis vim yog qhov kev tso cai ua haujlwm me me rau cov khoom.
Feem ntau, qhov poob ntawm graphite electrode tsawg dua li ntawm tooj liab electrode hauv kev ua haujlwm tsis zoo ntawm cov hluav taws xob loj thiab ntau dua li ntawm tooj liab electrode hauv kev ua tiav. Qhov poob ntawm electrode ntawm graphite electrode zoo sib xws.

1.3.Qhov zoo ntawm qhov chaw.

Lub cheeb tsam ntawm cov khoom siv graphite cuam tshuam ncaj qha rau qhov roughness ntawm EDM. Lub cheeb tsam me dua, qhov roughness ntawm qhov chaw qis dua tuaj yeem tau txais.
Ob peb xyoos dhau los, siv cov khoom siv graphite uas muaj 5 microns phi, qhov chaw zoo tshaj plaws tsuas yog ua tau VDI18 edm (Ra0.8 microns), niaj hnub no cov khoom siv graphite uas muaj phi hauv 3 microns, qhov chaw zoo tshaj plaws tuaj yeem ua tiav VDI12 edm ruaj khov (Ra0.4 mu m) lossis qib siab dua, tab sis graphite electrode siv edm los ua daim iav.
Cov khoom siv tooj liab muaj qhov tsis tshua muaj zog thiab cov qauv me me, thiab tuaj yeem ua tiav ruaj khov hauv qab cov xwm txheej nyuaj. Qhov roughness ntawm qhov chaw tuaj yeem tsawg dua Ra0.1 m, thiab nws tuaj yeem ua tiav los ntawm daim iav.

Yog li ntawd, yog tias qhov kev ua haujlwm tawm mus rau qhov chaw zoo heev, nws yog qhov tsim nyog dua los siv cov khoom siv tooj liab ua electrode, uas yog qhov zoo tshaj plaws ntawm tooj liab electrode dua li graphite electrode.
Tab sis tooj liab electrode nyob rau hauv qhov xwm txheej ntawm qhov chaw teeb tsa loj tam sim no, qhov chaw electrode yooj yim ua rau ntxhib, zoo li tawg, thiab cov ntaub ntawv graphite yuav tsis muaj teeb meem no, qhov xav tau ntawm qhov chaw roughness rau VDI26 (Ra2.0 microns) txog kev ua pwm, siv graphite electrode tuaj yeem ua tiav los ntawm kev ua tiav zoo mus rau kev ua tiav zoo, paub txog qhov cuam tshuam ntawm qhov chaw sib xws, qhov tsis zoo ntawm qhov chaw.
Tsis tas li ntawd xwb, vim yog cov qauv sib txawv ntawm graphite thiab tooj liab, qhov chaw tawm ntawm qhov corrosion ntawm graphite electrode yog qhov tsis tu ncua ntau dua li ntawm tooj liab electrode. Yog li ntawd, thaum tib qhov roughness ntawm VDI20 lossis siab dua raug ua tiav, qhov granularity ntawm qhov workpiece uas ua los ntawm graphite electrode yog qhov sib txawv ntau dua, thiab qhov cuam tshuam ntawm qhov chaw no zoo dua li qhov cuam tshuam ntawm qhov tawm ntawm tooj liab electrode.

1.4.Qhov tseeb ntawm kev ua haujlwm.

Tus coefficient ntawm thermal expansion ntawm cov khoom graphite yog me me, tus coefficient ntawm thermal expansion ntawm cov khoom tooj liab yog 4 npaug ntawm cov khoom graphite, yog li hauv kev ua cov txheej txheem tso tawm, graphite electrode tsis tshua muaj kev hloov pauv dua li tooj liab electrode, uas tuaj yeem tau txais kev ua tiav ruaj khov thiab txhim khu kev qha dua.
