Dab tsi yog cov ntaub ntawv ua cov khoom siv graphite?
Muaj peb yam tseem ceeb ntawm kev ua cov graphite electrode: txoj kev vibration pressurized, CNC automatic forming method thiab mechanical processing method.
(1) Pressurized vibration method: Cov txheej txheem kev vibration pressurized yuav tsum tau siv lub tshuab tshwj xeeb, thiab cov electrode tswv pwm yog qhov txawv ntawm cov electrode zoo. Cov khoom siv graphite thiab cov cuab yeej tsim tau muab tso rau qhov sib txawv rau ib leeg thaum ua, tawm hauv qhov sib txawv. Cov kua ua kua tov nrog dej thiab abrasive yog txhaj rau hauv nws. Thaum dhau los ntawm kev ua kua, cov graphite thiab cov cuab yeej tsim yog ultrasonically vibrated. Nyob rau hauv qhov kev cuam tshuam ntawm abrasive, graphite yog me ntsis tev tawm los tsim cov duab xav tau. Cov abrasive yog SiC, B4C lossis pob zeb diamond. Lub coarser lub abrasive, qhov ceev ceev ntawm kev ua. Lub tshuab cuab yeej txais kev kaw thiab cov ntaub thaiv dej rau kev ua haujlwm. Nws yog tsim rau EDM ua rau ntau lawm.
(2) CNC tsis siv neeg txoj kev sib sau: CNC tsis siv neeg txoj kev tsim yuav tsum tau tshwj xeeb graphite electrode txoj kev tshuab, uas siv CNC txoj kev, muaj ib tug tsis siv neeg hloov cuab tam, thiab muaj peev xwm haum rau ntau yam cuab yeej. Txhawm rau txhim kho kev ua haujlwm ib puag ncig, kev ua haujlwm graphite electrode yog ib puag ncig los ntawm cov ntaub thaiv dej kom tsis txhob graphite plua plav tawm ntawm txhua qhov chaw. Xwb, ntub machining tuaj yeem siv tau, nrog cov dej-soluble txiav cov kua tiv thaiv cov cuab yeej hnav thiab graphite plua plav ya. Lub tshuab cuab yeej muaj cov lim dej ua haujlwm siab uas tuaj yeem cais cov kua dej thiab cov graphite chips, kom ntseeg tau tias kev siv lub sijhawm ntev. Nws yog cov cuab yeej tshwj xeeb zoo tshaj plaws rau graphite electrode machining thiab tsim nyog rau electrode machining rau pwm. Txawm li cas los xij, nws tus nqi kuj yog siab heev thiab tsis tau siv dav hauv Suav teb.
(3) Mechanical machining method: Mechanical machining method is the main method used by general mold production units in China.
Graphite cov ntaub ntawv tuaj yeem ua tiav los ntawm kev tig, milling, drilling thiab sib tsoo. Tsis tas li ntawd, cov ntaub ntawv graphite yog cov plua plav ya thaum lub sijhawm siv tshuab, uas muaj kev cuam tshuam tsis zoo rau cov khoom siv thiab cov neeg ua haujlwm.
