1. Kev txiav yuav tsum pib ntawm ntug; txiav los ntawm ntug kom ntau li ntau tau, thiab tsis txhob txiav los ntawm perforation. Siv cov ntug raws li qhov pib taw tes yuav ua rau lub neej ntev ntawm cov khoom siv, txoj kev raug yog tsom lub nozzle ncaj qha rau ntawm ntug ntawm lub workpiece ua ntej pib lub plasma arc.
2. Txo qhov tsis tsim nyog" pib arc" sij hawm; kev noj ntawm nozzle thiab electrode yog ceev heev thaum pib lub arc. Ua ntej pib, lub teeb hluav taws xob yuav tsum tau muab tso rau hauv qhov kev taug kev deb ntawm cov hlau txiav.
3. Tsis txhob overload lub nozzle; overloading lub nozzle (uas yog, tshaj qhov ua hauj lwm tam sim no ntawm lub nozzle) yuav sai sai nozzle, thiab tam sim no siv yuav tsum yog 95% ntawm lub tam sim no ua hauj lwm ntawm lub nozzle. Piv txwv li: lub amperage ntawm 100A nozzle yuav tsum tau teem rau 95A.
4. Siv qhov txiav txiav kom tsim nyog; Raws li qhov yuav tsum tau ua ntawm phau ntawv qhia, txais yuav ib qho kev txiav kom tsim nyog. Qhov kev ncua deb yog qhov kev ncua deb ntawm qhov txiav nozzle thiab qhov chaw ntawm lub workpiece. Thaum perforating, sim siv 2 zaug ntawm qhov kev txiav ib txwm.
5. Lub perforation thickness yuav tsum nyob rau hauv qhov kev tso cai ntawm lub tshuab system; lub tshuab txiav tsis tuaj yeem perforate steel phaj siab tshaj qhov ua haujlwm tuab, thiab cov thickness perforation li niaj zaus yog 1/2 ntawm ib txwm txiav thickness.
6. Sim ua kom lub CNC txiav taws thiab cov khoom siv huv si huv si: txhua qhov av ntawm lub teeb thiab cov khoom siv yuav cuam tshuam rau kev ua haujlwm ntawm cov ntshav plasma. Muab cov khoom siv rau ntawm qhov chaw huv si thaum hloov cov khoom siv hluav taws xob, tshawb xyuas qhov sib txuas sib txuas ntawm cov tav nquag, thiab ntxuav cov electrodes thiab nozzles nrog xab npum.
7. Tsawg perforation thiab txiav. Perforation yuav ua rau molten hlau txaws rov qab thiab puas lub nozzle. Qhov no yog ib qho ntawm cov laj thawj tseem ceeb rau kev puas tsuaj nozzle. Yog hais tias perforation thiab txiav yuav tsum tau ua, thawj drilled pre-drilled qhov nrog ib tug xyaum me ntsis ntawm lub perforation, thiab ces xyaum los ntawm lub pre-drilled qhov. pib txiav;
8. Sim txiav tsis pub dhau qhov ntsuas ib txwm txiav tuab ntawm lub tshuab txiav, thiab sim tsis txhob txiav ntawm qhov txwv txiav thickness. Qhov ib txwm txiav tuab ntawm cov tshuab txiav hauv tsev feem ntau yog 60% ntawm cov txiav thickness cim los ntawm cov chaw tsim khoom (piv txwv li, domestic 100A plasma txiav tshuab manufacturers Cov cim txwv txiav thickness feem ntau yog 32 hli, tab sis qhov kev txiav thickness feem ntau tsuas yog 15-20mm. );
9. Qhov kev ncua deb ntawm qhov txiav nozzle thiab cov phaj hlau yuav tsum tau khaws cia kom tsis tu ncua, feem ntau nyob ib ncig ntawm 3-8mm. Yog hais tias nws nyob deb dhau lawm, tsis tsuas yog lub hwj chim noj yuav loj dhau lawm, lub peev xwm nkag mus rau hauv kev txiav yuav txo qis, tab sis kuj yuav siv cov electrode, uas yuav txo tau lub neej kev pab cuam ntawm electrode; Nyob rau yav tom ntej, nws yooj yim dua, thiab nws yuav siv ntau lub nozzles. Lub neej kev pabcuam ntawm lub nozzle yuav raug muab faib ua ob npaug, thiab nws yuav raug hlawv sai li sai tau thaum nws nce mus;
