Cutting-plasma metal. imishini ngensimbi

Plasma ahlabayo isetshenziswa ngokucubungula metal conductive. indaba kusetshenzwe uthola amandla amaningi avela umthombo wamandla ngokusebenzisa igesi ionized. Uhlelo ejwayelekile kuhlanganisa a wamanje umthombo wesifunda kanye umsiki ukuthungela ezinikeza ugesi, ionization futhi ulawule ezidingekile eliphezulu ahlabayo ngezinto ezihlukahlukene.

Ukuhoxa njalo umthombo zamanje usetha ukushuba nesivinini kucutshungulwa impahla kanye isekela arc.

Circuit ukuthungela wenziwa endaweni ephezulu imvamisa AC voltage obuyizinkulungwane 5-10. Ngo imvamisa of 2 MHz, okuyinto kwakha arc ephezulu umfutho ionizing igesi esimweni plasma.

A umsiki umnikazi izingxenye ezingaqedwa - umlomo wombhobho kanye electrode - futhi inikeza ukupholisa igesi noma amanzi la izingxenye. Umlomo wombhobho kanye electrode ziya onomfutho futhi zigcinwe jet ionised.

izinhlelo aphathwayo kanye ngomshini ufeze izinjongo ezihlukahlukene futhi zidinga imishini ezahlukene. Kuphela umsebenzisi angakwazi ukunquma ukuthi iyiphi kuzo okufanelekela kangcono izidingo zakhe.

Plasma cutting metal kuyinqubo ezishisayo lapho kwavela khona inhlansi igesi ionized heats kwensimbi conductive lokushisa ngenhla ukuncibilika yayo iphuzu, bese isusa kwensimbi oncibilikisiwe ngokusebenzisa ivulekile. Phakathi electrode e ithoshi, okuyinto itawufika engemihle, futhi workpiece nge engaba omuhle, i arc kwenzeka, ukusika izinto igesi ekusakazeni ionized ngaphansi kwengcindezi ezingeni lokushisa kusuka 770 kuya 1400 ° C. I-plasma jet (igesi ionized) bagxila badabula umlomo wombhobho, lapho onomfutho futhi iba ukwazi ancibilike wanquma ezihlukahlukene izinsimbi. Lena inqubo eziyisisekelo imanuwali futhi ngomshini plasma ahlabayo.

isandla ahlabayo

Manual cutting-plasma metal wenziwa usebenzisa amadivaysi ngokwanele encane nge ithoshi plasma. Bona ezikwazi, isebenziseka ngezindlela eziningi futhi ingasetshenziswa imisebenzi ehlukene. amakhono zabo ziyisiliva emandleni samanje uhlelo ahlabayo. izilungiselelo ahlabayo inhlukano ipharamitha isukela 7-25 ukuze 30-100 A A. Amanye amadivayisi, Nokho, enze kube nokwenzeka ukuba athole kuze kube Amps 200, kodwa abawona evamile kabanzi. In izinhlelo yebhukwana njengoba plasma negesi zokuzivikela ngokuvamile esetshenziselwa isitshalo emoyeni. Ziklanyelwe ukuze ingasetshenziswa ne ezahlukene voltage engenayo, okuyinto ziyahlukahluka kusuka 120 kuya 600 futhi lisetshenziswa amanethiwekhi single- noma ezintathu okhombisa.

plasma Manual ukusika metal ngokuvamile usetshenziselwa ukwenza workshop, wahlanganyela ukucutshungulwa izinto mncane, amasevisi isitshalo ukugcinwa, ukukhanda izitolo, Scrap metal eyamukelayo amaphuzu, kuyilapho kusakhiwa ihholo futhi inhlangano isebenza shipbuilding, auto-workshops kanye art workshop. Njengomthetho, isetshenziswa ukunquma insalela. Kuvamile-plasma 12 kudivayisi amp ukusikeka kuze 5 mm we ungqimba metal ngesivinini 40 mm ngomzuzu. kudivayisi 100-ampere enquma 70 mm obukhulu ijubane 500 mm / imiz.

Ngokuvamile, uhlelo Lencwajana akhethiwe kuye ngokuthi ukushuba impahla kanye oyifunayo processing speed. Idivayisi ukuthi ihlinzeka amperage okusezingeni eliphezulu, ngokushesha. Nokho, lapho ukusika zamanje okusezingeni eliphezulu kuba nzima ukulawula izinga lomsebenzi.

machining

Ngomshini plasma cutting metal akhiqizwa izitshalo, okuyinto, njengoba umthetho, okuningi inhlukano kakhudlwana futhi isetshenziswa ngesikhathi esifanayo ne etafuleni ahlabayo, kuhlanganise a okugeza amanzi noma nge platform ifakwe motors ehlukahlukene actuators. Ngaphezu kwalokho, uhlelo ngomshini ifakwe ukuphakama CNC elawulwa we jet ahlabayo ikhanda ukuthi singafaka voltage esethiwe nokulawula ithoshi ukuphakama. Ngomshini plasma uhlelo ahlabayo ingafakwa kwamanye imishini ukucutshungulwa metal, ezifana ukucindezela nginyathela, laser bezihlahla kanye izinhlelo kunendawo enkulu engahlolwa amarobhothi. Usayizi ukucushwa ngomshini incike ubukhulu etafuleni kanye yesikhulumi esetshenziswa. Ukuphuca umshini kungase kube kuncane kunokwabanye 1200h2400 mm nesikhulu kunabo 1400h3600 mm. izinhlelo ezinjalo azizintsha neze mobile kakhulu, ngakho ngaphambi kokufakwa, kufanele uhlinzeke zonke izingxenye zawo, kanye indawo yabo.

amandla Izidingo

Standard ugesi libe nenani amperage basukela 100 kuya 400 A ukusika-oksijini evela 100 kuya kwangu-600-A i-nitrogen. izinhlelo eziningi usebenza ububanzi ephansi, isib, kusuka 15 kuya 50 I. Kunezinye izinhlelo ebukhali nitric nge samanje 1000 A nangaphezulu, kodwa awavamile. voltage lokokufaka ngomshini plasma izinhlelo 200-600 in inethiwekhi ezintathu okhombisa.

yezimfuneko igesi

Ukuze ukusika steel esithambile futhi insimbi engagqwali, aluminium, futhi izinto ezihlukahlukene ezingavamile evame ukusetshenziswa umoya onomfutho, umoya-mpilo, i-nitrogen, futhi inhlanganisela argon ne-hydrogen. Inhlanganisela yawo futhi bakhonze njengamaphayona wesigiyani plasma ukwakha igesi. Ngokwesibonelo, lapho ukusika steel omnene kokuqala igesi ngokuvamile nitrogen plasma ukwakha - oxygen ne emoyeni onomfutho isetshenziswa njengenhlangano asizayo.

Oxygen isetshenziselwa elithambile carbon steel, ngoba uveza high quality ukusikeka impahla 70 mm obukhulu. Oxygen abangaba njengoba igesi plasma ngoba insimbi engagqwali kanye ne-aluminium, kodwa umphumela uba yini olunembile ngempela. Nitrogen ukhonza plasma negesi yesibili, ngoba inikeza ukuzisika kakhulu cishe kunoma iyiphi inhlobo metal. Isetshenziswa imisinga okusezingeni eliphezulu futhi bacubungule uthayela 75 mm obukhulu, futhi igesi njengoba asizayo nitrogen ne argon-hydrogen-plasma.

emoyeni ezicindezelwe - okuvame kakhulu njengoba igesi plasma bese asizayo. Lapho okulo senziwa cutting of uthayela a ukushuba 25 mm, kusale ebusweni oxidized. Lapho ukusika umoya, i-nitrogen, noma umoya-mpilo kuyinto igesi asizayo.

A ingxube argon ne-hydrogen, ngokuvamile esetshenziselwa ukwelapha insimbi engagqwali kanye ne-aluminium. Inikeza izinga okusezingeni eliphezulu Imi, futhi kuyadingeka ukuze ngomshini ahlabayo amaphepha ukujiya mkhulu kunezinhliziyo 75 mm. Carbon dioxide lungasetshenziswa njengenhlangano igesi elisizayo, ikhiqizwa lapho nitrogen plasma cutting metal, ngoba ivumela ukusebenza iningi izinto futhi kuqinisekisa ikhwalithi enhle.

A ingxube nitrogen ne-hydrogen ne-methane ngezinye izikhathi asetshenziswa inqubo plasma ahlabayo.

Yini ngidinga ngaphezulu?

Ukukhethwa plasma negesi asizayo - kuphela amabili sezinqumo ezibaluleke kakhulu okufanele kucatshangelwe uma ufaka noma usebenzisa ngomshini plasma uhlelo. Gilazi igesi angathengwa noma eziqashiwe, zitholakale lobehlukene, futhi uwugcine kubalulekile ukudala izimo ezifanele. Ukufakwa kohlelo kudinga imali ethe Izintambo zikagesi ezisobala kanye piping egesi futhi kokupholisayo. Ngaphandle ngomshini plasma uhlelo liyadingeka eyolanda etafuleni, ukusika umshini, CNC futhi iTHC. OEM-abakhiqizi ngokuvamile zinikeza ezihlukahlukene ongakhetha imishini ukuthi kufanelekile kunoma yikuphi ukucushwa kwedivayisi.

Kumbe siyadinga yini njengabanye imishini?

Ngenxa yokuba yinkimbinkimbi inqubo ukukhethwa ngomshini plasma ahlabayo, kufanele anikezwe isikhathi esiningi lokucwaninga ukucupha ezahlukene kanye simiso zindlela. Kufanele kuqashelwe:

• izinhlobo izingxenye lisuswe;
• inani imikhiqizo ezimbonini eziningi;
• ijubane oyifunayo futhi izinga ukusika;
• izindleko okudlekayo.
• izindleko ingqikithi yokusebenza ukucupha, kuhlanganise ugesi, igesi kanye nabasebenzi.

Usayizi, ukuma ngetincenye ekhiqizwa lungacacisa kudingekile zezimboni Industrial - uhlobo CNC amatafula nakuzingxenyekazi. Ngokwesibonelo, ukukhiqizwa izingxenye ezincane kungadinga platform ne drive ozinikele. Rack futhi pinion ngemoto, actuators, drive yokukhulisa umsindo Izinzwa esetshenziswa ezisekelweni ukuthi anqume izinga ukuzisika kanye ngesivinini esiphezulu ohlelweni.

Ikhwalithi nesivinini futhi kuncike onjani ukucutshungulwa metal imishini, le CNC bese kuthi amagesi asetshenziswa. uhlelo esinenjini zamanje adjustable futhi ukugeleza igesi ekuqaleni nasekupheleni Imi kunciphisa ukusetshenziswa impahla. Ngaphezu kwalokho, i-CNC nge semali inkumbulo nokukhetha izilungiselelo kungenzeka (isib ukuphakama ithoshi ekupheleni kwesigaba) futhi fast idatha ukucutshungulwa (input / okuphumayo wezokuxhumana) ukunciphisa Ukuphumula futhi ukwandisa isivinini kanye nokunemba ukusebenza.

Ekugcineni, isinqumo ukuthenga noma uthuthukise ngomshini plasma ahlabayo uhlelo noma ekusebenziseni le ncwadi kumelwe kube nengqondo.
