Ithusi iyinsimbi evamile edinga kakhulu ukusikwa nge-laser ngoba ibonisa ukukhanya kwe-infrared futhi ihambisa ukushisa kude nendawo yokusika ngokushesha. Lesi sihloko sichaza i-physics ngemuva kwalezo zinselele, ukuthi imikhawulo engokoqobo ingakanani kuma-fiber laser anamandla aphakathi nendawo kusetshenziswa idatha eqinisekisiwe yomshini we-Xinhong, ukuthi ukukhethwa kwegesi yokusiza kuthinta kanjani ukusika, nokuthi yinini i-waterjet, i-plasma, noma ukusika nge-shear kunengqondo ngaphezulu.
Ikhopha livela kakhulu ezicelweni zezilinganiso — ama-busbar, izixhumo zikagesi, izingxenye ze-heat exchanger, izinto zokuxhuma umhlabathi — futhi futhi iyinto eyenza abathengi abaningi be-laser badideke kunanoma yini enye. Izakhiwo ezifanayo ezenza ithusi libe yigugu emsebenzini kagesi ziyenza kube nzima ukuyisika ngokukhanya. Lesi sihloko sichaza ukuthi kungani, ukuthi imikhawulo engokoqobo ingakanani kuma-fiber laser anamandla aphakathi nendawo, ukuthi ukukhethwa kwegesi yokusiza kushintsha kanjani umphumela, nokuthi yinini enye inqubo yokusika eyisinqumo esingcono.
Kungani Ithusi Liyinsimbi Evamile Enzima Kakhulu Ukusikwa Nge-Laser
Izakhiwo ezimbili zomzimba zisebenza ngokumelene ne-laser ngasikhathi sinye.
Ukubonisa okuphezulu kubude begagasi le-laser
Ama-fiber laser akhipha ukukhanya ngobude begagasi elicishe libe yi-micrometer eyodwa (i-near-infrared). Ithusi lingenye yezinsimbi ezibonisa kakhulu kuleli banga — ingxenye enkulu ye-beam engenayo iyaphindisela ebusweni esikhundleni sokumuncwa. Kuze kube yilapho ubuso bushisa futhi buqala ukuncibilika, i-beam idlulisela amandla amancane kuyo into. Uma ukuncibilika kuqala, ukumuncwa kuba ngcono, kodwa ukufika kulelo phuzu kudinga amandla amakhulu kakhulu kunaleyo edingekayo ensimbi.
Ukukhanya okubonisiwe akuyona nje inkinga yokusebenza kahle. Emishinini ezilungiselelwe kabi, amandla abonisiwe angabuya ehle nge-fiber aye emthonjeni. Imithombo yesimanje ye-fiber laser ifaka ukuvikelwa kokubonisa emuva, kodwa ukulungiselelwa kwenqubo kusamathela: indawo yokugxila efanele, isimo esihlanzekile sobuso, namandla anele okugxila konke kunciphisa inani lamandla ishidi eliwabuyisela kuma-optics.
Ukuhambisa ukushisa okuphezulu
Ithusi lihambisa ukushisa ngokushesha izikhathi ezimbalwa ukudlula insimbi yekhabhoni. Noma yimaphi amandla i-beam ewafaka asakazeka kude nendawo yokusika cishe ngokushesha, ngakho insimbi iyamelana nokufinyelela izinga lokuncibilika endaweni. Ngokomsebenzi lokhu kusho ukuthi indawo yokusika idinga ukugxila kwamandla aphezulu okusimeme, futhi ithusi elincanyana lingaziphatha ngendlela engalindelekile uma amapharamitha emisiwe — ukusika kungaqala bese kulahlekelwa umfutho njengoba ukushisa kudonsela eshidini elizungezile.
Inhlanganisela yokumuncwa okuphansi nokulahlekelwa ukushisa okuphezulu yiyo eyenza i-fiber laser ekwazi ukusingatha insimbi yekhabhoni engu-6mm ibe nomthamo wethusi ophansi kakhulu. Lesi yisici sencwadi, hhayi iphutha emshinini, futhi noma yimuphi umhlinzeki ocaphuna ngothusi obukhulu ngamandla angena ngaphansi kufanele ahlolwe. Ukuze uthole ukuhlolisisa okujulile ngendlela efanayo ku-aluminium — enye insimbi engeyona eyesimbi ekhanyisa kakhulu — bheka isihloko sethu esithi ukusika i-aluminium nethusi nge-fiber laser: ukubonisa kanye nemikhawulo yobukhulu.
Ubukhulu Bethusi Obungokoqobo Ngamandla Omshini
Ngenxa yokuthi umthamo wethusi awukhuli ngendlela umthamo wensimbi okhula ngayo, indlela eqotho yokuhlola umshini ukubheka lokho umkhiqizi akucacisayo ngempela ngethusi — hhayi amandla aphezulu. Uma ufuna isithombe esibanzi sokuthi amandla e-laser ahumusha kanjani kubukhulu bamapuleti nasekwakhekeni komshini kulo lonke uhla, umhlahlandlela wethu wokuthenga wokuthenga umshini wokusika nge-fiber laser onamandla aphezulu uhlanganisa lonke uhla lwamandla. Nansi into imishini yethu ecaciselwe ukuyenza.
| Umshini | Ikhono lethusi | Eminye imininingwane eshiwo |
| Umshini Wokusika Nge-Fiber Laser ongu-1500W | Ithusi kuze kufike ku-3mm | Insimbi yekhabhoni kuze kufike ku-6mm, i-aluminium kuze kufike ku-4mm, ukunemba kwe-±0.03mm, umbhede ongu-1300×2500mm, opholile ngamanzi, i-CE/RoHS |
| Umshini Wokusika Nge-Fiber Laser Omkhulu ongu-1000W | Ithusi lifakwe phakathi kwezinto ezisekelwayo ebangeni lezinto lika-1–12mm (insimbi engaguli, insimbi yekhabhoni, ithusi, i-titanium) | Umbhede ongu-3000×1500mm noma ongu-4000×2000mm |
Amaphuzu amabili okufanele uwafunde ngokucophelela:
I- 1500W fiber laser cutting machine inomkhawulo ocacile wethusi ongu-3mm. Leso sibalo sesivele sibonisa ubunzima bethusi — umshini ofanayo usika insimbi yekhabhoni engu-6mm, okuphindwe kabili kumthamo wethusi. Uma umsebenzi wakho wethusi ikakhulukazi ishidi nepulethi engu-1–3mm, leli klasi lomshini liyikwazi ngokukhululeka.
I- 1000W large format fiber laser cutting machine imininingwane ibala ithusi phakathi kwezinto ezizisekelayo ebangeni lika-1–12mm, kanye nensimbi engaguli, insimbi yekhabhoni, ne-titanium. Ukuze uthole izingxenye zethusi ezijulile, indlela engokoqobo iwukuqinisekisa ubukhulu bakho obuthile ne-alloy nomhlinzeki ngaphambi kokuzibophezela, ngoba ubukhulu bethusi obufinyeleleka ngamandla anikeziwe buncike ku-alloy, ekuqedeni kobuso, nasekuthuthukisweni kwamapharamitha — hhayi emandleni kuphela.
Qaphela esikushoyo hhayi esikushoyo: imishini yethu yeklasi lika-20kW no-30kW ibala i-aluminium emininingwaneni yayo kodwa ayikhiphi izibalo zokusika ithusi. Ungalokothi ucabange ukuthi isilinganiso samandla aphezulu sihumusha ekhonweni lethusi elijiyile; buza idatha eqondene nethusi.
Ukukhethwa Kwegesi Yokuxhasa Yethusi
Igesi yokusiza yenza imisebenzi emithathu: ikhipha into encibilikile emgodini, ivikela ama-optics, futhi — kuye ngegesi — ingeza noma isuse ukushisa ekuphendukeni.
I-nitrogen (ukusika okungasebenzi)
I-nitrogen ayisebenzi nethusi, ngakho ukusika kuyinqubo yokuncibilika nokuphephela kuphela. Umgogodla wokusika uhlala ukhanyile futhi ungenawo i-oxide, okubalulekile kuma-busbar kagesi nasebusweni bokuxhumana lapho izingqimba ze-oxide zandisa ukumelana lapho kuxhunyaniswa. Okubi: i-nitrogen idinga ingcindezi ephezulu namandla aphezulu okugxila ukuze ikhiphe okuncibilikile, ngakho isebenzisa igesi eningi futhi, emshinini onikeziwe, yehlisa ubukhulu obukhulu uma kuqhathaniswa nomoya-mpilo. Emsebenzini wethusi wezinga likagesi amaningi, i-nitrogen iyisinqumo esizenzakalelayo.
Umoya-mpilo
Umoya-mpilo usebenza ngokukhipha ukushisa nezinsimbi eziningi futhi wengeza ukushisa ekusikeni, okusiza ukungena. Nethusi, inzuzo incane kunaleyo yensimbi — ithusi liyagqwala futhi ungqimba lwe-oxide lushintsha ukumuncwa, kodwa ukuphenduka akunamandla njengokushiswa kwe-iron-oxygen ensimbini yekhabhoni. Imiphetho yethusi esikwe ngumoya-mpilo iphuma igqwalile futhi ngokuvamile idinga ukuhlanzwa ngaphambi kokusetshenziswa kukagesi. Kungaba yinketho esebenzayo lapho izinga lomphetho lingabalulekile futhi isivinini sibalulekile, kodwa qinisekisa umphumela ku-alloy yakho nobukhulu ngaphambi kokuyenza ibe umgomo.
Umoya ocindezelwe
Umoya cishe ungumoya-mpilo ongu-21%, ngakho uziphatha njengokusika komoya-mpilo okuncane ngenani elincane legesi. Ukugqwala komphetho kufana noma kubi kakhulu kunomoya-mpilo. Ezitolo ezenza umsebenzi wethusi ngezikhathi ezithile lapho imiphetho izolungiswa noma iqedwe ngemuva, umoya ugcina izindleko zokusebenza ziphansi; ezingxenyeni zikagesi eziqediwe, bheka i-nitrogen.
Ithusi Elisikwe Nge-Laser Lisetshenziswa Kuphi
Iningi lesidingo sethusi elisikwe nge-laser livela ezinhlelweni zikagesi nezokushisa:
Ama-busbar nezixhumanisi zokusabalalisa — indodo yethusi eyisicaba noshidi olusikwe ngokomfanekiso, ngokuvamile olunamaphethini ezimbobo okuxhuma ngamabhawudi. Ukusika nge-nitrogen kugcina izindawo zokuxhumana zingenalo i-oxide.
Izixhumo zikagesi namatheminali — izingxenye ezincane ezenziwe ngomfanekiso lapho ukunemba kwe-fiber laser (i-±0.03mm kumsihni ongu-1500W njengoba kucacisiwe) kususa isinyathelo sokulungisa sesibili.
Izinto zokuxhuma umhlabathi nokuvikela i-EMI — ishidi lethusi elincanyana elisikwa ngobuningi.
Amaphaneli e-heat exchanger namapuleti abandayo — lapho izinga lomphetho wokusika nokulawulwa kwe-burr kubalulekile ekubrazini noma ekunamathiseleni kamuva.
Ithusi elincanyana yilapho ama-fiber laser ezithola khona inzuzo kule nto: ukuminyana okuphezulu kwe-nesting, akukho zinsimbi zokusebenza, nokushintsha okusheshayo kwezinhlelo phakathi kwezinguqulo zezingxenye.
Lapho Enye Inqubo Yenza Umqondo Ongcono
Ukusika nge-laser akusiyo impendulo efanele ngokuzenzakalela yethusi. Cabanga ngezinye izindlela kulezi zimo:
Izingxenye zethusi ezijiyile kakhulu. Ngaphezu kwebanga i-fiber laser yamandla aphakathi nendawo engalisingatha ngokuthembekile, ukusika nge-waterjet akunawo umkhawulo wobukhulu obekwe ukubonisa futhi akukhiqizi indawo ethintekile ukushisa — ngenani lokusika okunensayo kanye nomgodi obanzi.
Ukusika okuqondile okulula ezintweni eziyizindodo. I-bandsaw noma ishear ishibhile ngokusika ngakunye futhi ithusi ngokuvamile lizolungiswa ngomshini noma kunjalo.
Izingxenye ezincane zezinga eliphezulu lomphetho ngobuningi. Kwamanye amaphrofayili ethusi, ukusikwa ngamakhemikhali noma ukugxiviza kudlula ukusika nge-laser mayelana nesimo somphetho nezindleko zengxenye ngayinye ngobuningi — nakuba kukabili kunezindleko zokusebenza noma zokulungiselela ama-laser awagwilayo.
Ingozi enkulu yokubonisa kuma-foil amancane kakhulu. Ngaphansi kobukhulu obuthile, ukubonisa kwethusi kuba yingozi yangempela kuma-optics e-laser uma amapharamitha eshintsha; ama-foil ngokuvamile asetshenziswa kangcono ngokusikwa ngamakhemikhali noma ngokusika ngendlela.
Isivivinyo esifanele silula: uma ithusi lakho cishe liyishidi elingu-1–3mm futhi udinga izingxenye ezenziwe ngomfanekiso ngaphandle kwezinsimbi zokusebenza, i-fiber laser yeklasi lika-1000–1500W ifaneleka kakhulu. Uma umsebenzi wakho uyizindodo eziyindilinga noma ama-foil asezingeni eliphezulu, beka intengo yezinye izinqubo eceleni kwe-laser.
