Sab saum toj 5 Plasma Cutters rau Precision Txiav

Koj tau siv sijhawm ib teev kev sib tw nrog lub kaum sab xis grinder, cuam tshuam txhua qhov chaw, tsuas yog mus txog qhov tsis sib xws. Hauv kev muaj tiag, muaj txoj hauv kev sai dua, huv dua los txiav hlau-ib qho uas xav tias tsis muaj zog li kos nrog tus cwj mem, tsis yog kev sib ntaus sib tua tawm tsam lub tshuab loj. Nrhiav qhovzoo tshaj plaws plasma cutterrau koj lub khw hauv tsev kiag li hloov pauv koj li cas kho kho thiab cov phiaj xwm hnub so muaj tswv yim.

Xav txog cov cuab yeej no raws li lub teeb tsom teeb pom kev zoo nyob hauv koj txhais tes. Thaum sib piv aCNC plasma cuttervs oxy- roj teeb, nws sai sai pom tseeb tias plasma txiav tshuab- uas siv cov huab cua compressed los tsim ib qho ultra-siab- kub arc- tshem tawm qhov xav tau rau kev siv roj complex thiab kev kawm nkhaus ntev. Raws li cov txheej txheem tsim cov ntaub ntawv, cov plasma arc technology txiav cov hlau nrawm dua li cov txheej txheem kev txiav tshuab.

Nrog rau kev nce qib hauv cov thev naus laus zis niaj hnub no, cov cuab yeej siv uas ib zaug nruj nruj kev lag luam- qib tau dhau los ua qhov tsim nyog rau cov neeg nyiam DIY. Ua tsaug rau inverter txiav tshuab, qhov loj hauv kev hloov pauv yav dhau los tau hloov los ntawm cov khoom siv hluav taws xob ntse, lub teeb yuag; ntau cov qauv compact tuaj yeem txuas ncaj qha rau hauv cov qauv 110-volt hauv tsev qhov hluav taws xob yam tsis muaj kev cuam tshuam rau lub voj voog.

Los ntawm kev tswj kom meej ntawm cov lus qhia tsis meej, koj tuaj yeem nrhiav tau lub tshuab txiav plasma uas haum rau koj cov peev nyiaj thiab koj lub chaw nres tsheb qhov teeb tsa hluav taws xob tiag tiag -txawm tias koj tab tom kho cov yeeb nkab rusty lossis tsim vaj kos duab.

Ua ntej nqa lub tshuab txiav mus rau hauv tsev, koj yuav tsum xyuas seb nws puas yuav mus rau qhov chaw nres tsheb Circuit Court breaker. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm "cov tswv yim tam sim no" (lub zog rub tawm ntawm lub qhov hluav taws xob ntawm phab ntsa) thiab "tso tawm tam sim no" (lub zog thermal siv rau kev txiav ntawm lub teeb).

Koj tuaj yeem xav txog qhov tso zis tam sim no zoo li lub pob qhov ntim: tig nws tso cai rau koj txiav cov hlau tuab dua, tab sis qhov no los ntawm tus nqi ntawm kev kos ntau cov tswv yim tam sim no los ntawm koj lub tsev hluav taws xob hluav taws xob. Thaum kawg, rau DIY enthusiasts, lub zoo tagnrho plasma cutter yog ib tug uas muaj adjustable tam sim no, tso cai rau nws kom phim koj cov hluav taws xob uas twb muaj lawm teeb.

Kev lag luam specs feem ntau exaggerate, yog li ntawm no yog qhov koj lub tsev circuits tuaj yeem ua tau zoo rau kev txiav kom huv si:

• 15-Amp Circuit Court (Standard 110v):Zoo meej rau nws pib lub cev ntawv hlau mus txog 1/8-inch tuab.
• 20-Amp Circuit Court (Upgraded 110v):Yooj yim tuav lawnmower brackets thiab tso pa tawm mus txog 1/4-nti.
• 50-Amp Circuit Court (Dedicated 220v):Qhov tiag -lub ntiaj teb hlau tuab muaj peev xwm rau 50-amp tshuab ntaus nws qhov chaw qab zib ntawm 1/2-nti steel.

Xaiv cov khoom siv nrog dual -voltage (110V / 220V) fais fab mov ua tau raws li qhov xav tau tam sim no rau kev siv nrog cov qauv phab ntsa qhov hluav taws xob thaum tso cai rau kev hloov pauv rau cov chaw nres tsheb hauv xov tooj yav tom ntej.

Nws yog qhov txaus ntshai heev uas yuav tsum tau siv sijhawm ntau teev tshem tawm xeb thiab pleev xim rau kom txiav yooj yim. Nrog rau "pilot arc" thev naus laus zis, txawm li cas los xij, qhov kev npaj txaus ntshai no tsis tsim nyog. Ua haujlwm zoo li lub bolt txuas ntxiv ntawm xob laim, qhov tshwj xeeb no ua haujlwm rau plasma arc yam tsis xav tau kev sib cuag nrog cov hlau, tso cai rau koj txiav ncaj qha los ntawm cov kav dej xeb lossis cov laj kab pleev xim yam tsis muaj lub teeb txiav tawm.

Arc ignition txoj kev yog feem ntau categorized ua ob hom: "high-frequency ignition" thiab "blowback ignition." High-frequency ignition siv siab-voltage electric sparks, whereas blowback ignition relies on the internal pneumatic piston; tom kawg tsis cuam tshuam nrog cov khoos phis tawj nyob ze lossis cov khoom siv hluav taws xob rhiab hauv qhov chaw nres tsheb. Ob txoj kev tso cai rau lub teeb rau ntawm qhov chaw uas xav tau, yog li zam kom tsis txhob siab -kub slag spatter thiab tiv thaiv kev puas tsuaj tam sim ntawd rau cov khoom siv tooj liab.

Txhawm rau kom nkag siab txog lub tshuab ua tau zoo, ib tus yuav tsum paub qhov txawv ntawm "kev txiav" (siab- zoo txiav) thiab "severance cutting" (rough cutting) muaj peev xwm. Lub tshuab ntsuas rau ib qho -inch severance thickness feem ntau tsuas yog nyuam qhuav txiav los ntawm cov hlau, tawm hauv qab jagged npoo uas yuav tsum tau sib tsoo thiab ua tiav; nyob rau hauv sib piv, nws du peev xwm yog feem ntau tsuas yog nyob ib ncig ntawm ib nrab ib nti.

Yog tias koj siv lub zog ntau dhau thaum lub sijhawm ua haujlwm, lub cuab yeej yuav raug kaw vim overheating; Yog li ntawd, lub tswv yim ntawm "lub voj voog ua haujlwm" yog qhov tseem ceeb rau cov pib tshiab. Xav txog lub tshuab ua tus khiav: 60% lub luag haujlwm lub voj voog txhais tau tias nws tuaj yeem "sprint" rau 6 feeb tab sis yuav tsum tau "ntev nws ua pa" rau 4 feeb. Thaum txiav los ntawm ib qho rusty pa bracket feem ntau yuav tsis thawb lub cuab yeej mus rau qhov kev txwv no, koj yuav tsum tau ua raws li koj tus kheej thaum txiav ntev los ntawm cov hlau.

Airflow yog lwm qhov tseem ceeb. Txawm hais tias koj xaiv ib qho kev tsim- hauv compressor lossis ib qho chaw cua sab nraud, lub tshuab cua yuav tsum ua kom tau raws li lub cuab yeej CFM (cubic feet per minute) cov kev cai. Feem ntau DIY cutters xav tau ib qho airflow ntawm kwv yees li 4 CFM ntawm 60 PSI kom ua tau zoo tshuab molten hlau. Yog tias lub compressor hauv koj lub chaw nres tsheb tsis muaj kev ua haujlwm txaus, huab cua siab yuav poob, ua rau lub plasma arc tsis ruaj khov thiab ua rau jagged, tsis sib xws.

Txawm tias muaj huab cua zoo siab, cov dej seem seem hauv cov kab cua tuaj yeem ua rau cov tooj liab txiav nozzles sai sai. Cov dej noo ua rau lub siab -kub plasma arc tawg thiab ua tsis ruaj khov; Yog li ntawd, kom ntseeg tau tias cov cua qhuav qhuav yog qhov tseem ceeb tshaj plaws rau kev ua haujlwm ntev ntawm cov khoom siv hluav taws xob plasma.

Ua raws li daim ntawv txheeb xyuas ceev ceev no:

• Tshem cov dej los ntawm lub ntsiab compressor lub cua receiver tank txhua hnub.
• Nruab tus qauv ya raws- cais lim ncaj qha rau ntawm cov khoom siv.
• Ntxiv ib qho hauv - kab desiccant lim cartridge nrog cov xim - hloov qhov taw qhia kom tshem tawm qhov seem ntawm cov dej seem.

Khaws cov khoom siv kom qhuav thiab txias tsis yog tsuas yog ua kom muaj txiaj ntsig zoo tshaj plaws xwb tab sis kuj tsim cov kev mob zoo rau kev ua haujlwm siab -precision thiab txo cov dross thiab pov tseg.

Thaum rub lub trigger kom txiav yog qhov zoo siab heev, txav ntawm qhov tsis ncaj ncees lawm ua rau cov npoo jagged thiab tsub zuj zuj ntawm solidified hlau droplets hu ua "dross." Kev txav nrawm dhau ua rau cov nplaim hluav taws tso ncaj qha rau ntawm tus neeg teb xov tooj, thaum txav mus qeeb dhau yuav ua rau muaj kev txiav ntxhib los ntawm cov kab hluav taws xob melting ntau dhau ntawm cov khoom. Cov txheej txheem txiav zoo tshaj plaws yog zoo li cov kab tracing nrog cov cim: siv cov lus tsa suab tsis tu ncua ncaj qha hla lub workpiece nto ua rau koj txhais tes ruaj khov, ua kom huv si, zoo nkauj txiav.

Qhov sib txawv tsim tom qab lub laser lossis plasma beam vaporizes cov khoom yog lub npe hu ua "kerf width," thiab tuav lub nqaim kerf yog qhov tseem ceeb rau siab -precision txiav. Thaum daws teeb meem xws li kev txiav tsis zoo lossis kev poob qis, cov novices feem ntau yuam kev xav tias lawv yuav tsum nce qhov tam sim no; nyob rau hauv kev muaj tiag, tsa cov roj siab yog zoo dua. Lub zog muaj zog ntau dua ua rau cov arc thiab tshuab molten steel ua ntej nws tuaj yeem ua raws li cov hlau nto.

Kev nkag siab txog cov yam ntxwv ntawm kev ua haujlwm no pab xaiv lub tshuab plasma uas haum rau kev siv hauv tsev. Xaiv lub tshuab nruab nrog ib qho yooj yim -rau- siv, ua - nyob rau hauv siab regulator tso cai rau koj los kho qhov tsis yooj yim dua thiab ua tiav cov txiaj ntsig zoo.

Txhawm rau xaiv qhov zoo tshaj plaws plasma cutter rau kev siv hauv tsev, tsuas yog ua raws li peb cov kauj ruam yooj yim: xyuas koj lub chaw nres tsheb qhov hluav taws xob thauj khoom txwv, teeb tsa cov peev nyiaj tsim nyog, thiab xaiv hom tsev raws li qhov tuab ntawm cov ntaub ntawv koj feem ntau ua haujlwm nrog.

Ua ntej koj pib txiav, koj yuav tsum tau nruab koj tus kheej nrog cov cuab yeej kev nyab xeeb tsim nyog los tiv thaiv UV rays thiab kub sparks.

Npaj cov khoom tseem ceeb hauv qab no:

• Cov tsom iav kev nyab xeeb nrog qhov ntsuas Shade 5 (tus qauv vuam kaus mom hlau feem ntau yog tsaus dhau).
• Heavy-cov hnab looj tes tawv tawv.
• Nplaim taws-resistant apron.

Thaum koj tau qhia meej txog koj cov kev ua haujlwm thiab sau koj cov cuab yeej kev nyab xeeb, thaum kawg koj tuaj yeem hais lus zoo rau qhov loj, qhov tsis zoo ntawm lub kaum sab xis thiab hloov mus rau lub cuab yeej uas hla cov hlau yooj yim li txiav butter.
