Iyini i-CNC plasma cutter?
I-CNC Plasma cutting iyinqubo enqamula ezintweni ezisebenza ngogesi kusetshenziswa indiza esheshayo ye-plasma eshisayo. Izinto ezijwayelekile ezisikwe ngethoshi le-plasma zifaka insimbi, i-aluminium, ithusi nethusi, nakuba ezinye izinsimbi zokuqhuba zingasikwa. I-CNC Plasma cutter ivamise ukusetshenziswa ezitolo zokwenziwa, ukulungisa nokuvuselela izimoto, ukwakhiwa kwezimboni, kanye nemisebenzi yokuhlenga nokuchitha. Ngenxa yesivinini esikhulu nokusikeka okunembayo okuhlanganiswe nezindleko eziphansi, i-CNC plasma cutter ibona ukusetshenziswa okubanzi kusuka kuzinhlelo zokusebenza ze-CNC zezimboni ezinkulu kuya ezitolo ezincane zokuzilibazisa.
Inqubo eyisisekelo yokusika i-plasma ye-CNC ihilela ukudala umgudu kagesi wegesi eshisa kakhulu, ene-ionized kagesi okungukuthi i-plasma esuka ku-CNC plasma cutter ngokwayo, ngokusebenzisa ucezu lomsebenzi ozosikwa, ngaleyo ndlela yakhe isekethe kagesi eqediwe ibuyele ku-CNC plasma cutter nge-grounding clamp. Lokhu kufezwa igesi ecindezelwe (umoya-mpilo, umoya, i-inert nokunye kuye ngento esikwayo) ephephethwa ngombhobho ogxilile ngesivinini esikhulu ukuya endaweni yokusebenza. I-arc kagesi ibe seyakheka ngaphakathi kwegesi, phakathi kwe-electrode eduze noma ehlanganiswe kubhobho legesi kanye nomsebenzi ngokwawo. I-arc kagesi i-ionize enye igesi, ngaleyo ndlela idale umgudu osebenza ngogesi we-plasma. Njengoba ugesi ovela kuthoshi lokusika wehla kule plasma uletha ukushisa okwanele ukuze uncibilike endaweni yokusebenza. Ngesikhathi esifanayo, ingxenye enkulu ye-plasma yesivinini esiphezulu kanye negesi ecindezelwe iphephezela insimbi encibilikisiwe eshisayo, ngaleyo ndlela ihlukanise okungukuthi ukusika ucezu lomsebenzi.
Kusukela I-CNC plasma cutters khiqiza "i-cone" eshisa kakhulu futhi yasendaweni ongasika ngayo, iwusizo kakhulu ekusikeni insimbi yeshidi ngomumo ogobile noma onama-angled.
Izisiki ze-plasma ze-Analog CNC, ngokuvamile ezidinga ama-kilowatts angaphezu kwama-2, zisebenzisa isiguquli esisindayo se-mains-frequency. Ama-inverter plasma cutters alungisa ukunikezwa kwe-mains ku-DC, efakwa kusiguquli esishintshashintshayo se-high-frequency transistor phakathi kuka-10 kHz kuya cishe ku-200 kHz. Amafrikhwensi aphezulu okushintsha avumela i-transformer encane eholela kusayizi ophelele kanye nokwehliswa kwe-w8.
Ama-transistors asetshenziswa ekuqaleni bekungama-MOSFET, kodwa manje aya ngokuya asebenzisa ama-IGBT. Ngama-MOSFET ahambisanayo, uma enye yama-transistors isebenza ngaphambi kwesikhathi ingaholela ekwehlulekeni kokwehla kwekota eyodwa ye-inverter. Okusungulwe kamuva, ama-IGBT, awekho ngaphansi kwale modi yokwehluleka. Ama-IGBT ngokuvamile angatholakala emishinini yamanje ephezulu lapho kungenakwenzeka khona ukuhambisana nama-transistors e-MOSFET anele.
I-topology yemodi yokushintsha ibizwa ngokuthi i-dual transistor offline offline converter. Nakuba ilula futhi inamandla kakhulu, ezinye izinqamuli ze-plasma ze-inverter, ikakhulukazi lezo ezingenawo amandla okulungisa isici, azikwazi ukuqhutshwa zisuka kujeneretha (lokho kusho ukuthi umenzi weyunithi yokuguqula uyakwenqabela ukwenza kanjalo; isebenza kuphela kumajeneretha amancane, aphathwayo alula). Nokho amamodeli amasha anomjikelezo wangaphakathi ovumela amayunithi angenawo ukulungiswa kwesici samandla ukuthi asebenze kumajeneretha wamandla okukhanya.
Abanye abakhiqizi be-CNC plasma cutter bakha amatafula okusika e-CNC, kanti abanye bane-cutter eyakhelwe etafuleni. Amathebula e-CNC avumela ikhompuyutha ukuthi ilawule ikhanda lethoshi ikhiqize ukusikeka okucijile okuhlanzekile. Imishini yesimanje ye-CNC plasma iyakwazi ukusika i-multi-axis yezinto eziwugqinsi, okuvumela amathuba emishini yokushisela eyinkimbinkimbi engenakwenzeka ngenye indlela. Okokusebenza okuzacile, ukusika kwe-CNC plasma kushintsha kancane kancane ngokusikwa nge-laser, ngenxa ikakhulukazi yamakhono aphezulu okusika imbobo komsiki we-laser.
Ukusetshenziswa okukhethekile kwe-CNC Plasma Cutters bekusembonini ye-HVAC. I-Software icubungula ulwazi kuma-ductwork futhi idale amaphethini ayisicaba azosikwa etafuleni lokusika ngethoshi ye-plasma. Lobu buchwepheshe bukhulise kakhulu umkhiqizo ngaphakathi kwemboni kusukela yethulwa ekuqaleni kwawo-1980.
