Izinkinga eziyisithupha ezivamile kanye nezixazululo zomshini wokusika i-fiber laser
1, Ubuchwepheshe bokusika nokubopha imishini ye-laser
Enkambisweni yokusika eshisayo, ngaphandle kwezimo ezimbalwa lapho ukusika kungenziwa ngqo kusuka emaphethelweni eshidi, ngokuvamile kuyadingeka ukubhoboza imbobo yokuqala kusenesikhathi eshidini. Emishinini yokusika i-fiber laser ngaphandle kwamadivayisi okunyathela, izindlela ezimbili zokubhoboza ezilandelayo zisetshenziswa kakhulu:
- Ukubhoboka kwe-Pulse
Isimiso: Ukusebenzisa i-laser enamandla aphezulu kakhulu ukuncibilikisa noma ukuhwamukisa inani elincane lezinto. Umoya noma i-nitrogen kuvame ukusetshenziswa njengegesi elisizayo, elinomfutho ophansi kunomfutho we-oxygen ngesikhathi sokusika, ukunciphisa ukwanda kosayizi wembobo okubangelwa yi-oxidation ye-exothermic. I-pulse ngayinye ikhiqiza ama-jet amancane kuphela angena kancane kancane ezintweni.
Izici:
Ububanzi bokubhoboza buncane futhi ikhwalithi ingcono kunezimbobo eziqhumayo.
Isikhathi sokubhoboza amapuleti amakhulu side kakhulu, ngokuvamile sithatha imizuzwana embalwa.
Izidingo eziphezulu zibekwe kuma-laser, adinga amandla aphezulu okukhipha kanye nesikhathi esihle sokukhanya kanye nezici zesikhala.
Kudingeka uhlelo lokulawula indlela yegesi oluthembekile ukuze kufezwe ukulawula okunembile kohlobo lwegesi, ukushintsha kwengcindezi, kanye nesikhathi sokubhoboza.
Ukuthuthukiswa kobuchwepheshe bokushintsha: Uma ushintsha kusuka ekubhobozeni kwe-pulse engaguquki kuya ekusikeni okuqhubekayo okuqhubekayo, ukuze uthole ukusikwa kwekhwalithi ephezulu, ukukhiqizwa kwezimboni kufeza kakhulu ushintsho olubushelelezi ngokushintsha amandla ajwayelekile e-laser. Izindlela ezithile zifaka phakathi ukushintsha ububanzi be-pulse, ukushintsha imvamisa ye-pulse, noma ukushintsha kokubili ngasikhathi sinye. Umkhuba ukhombisile ukuthi ukushintsha kokubili ububanzi be-pulse kanye nemvamisa ngasikhathi sinye kuveza imiphumela emihle kakhulu.
- Ukubhoboka Kokuqhuma
Isimiso: Ngemva kokushiswa ngemisebe ye-laser okuqhubekayo, kwakheka umgodi phakathi nendawo, bese izinto ezincibilikisiwe zisuswa ngokushesha nge-oxygen flow coaxial enogongolo lwe-laser, kwakhiwe umgodi.
Izici:
Usayizi wombhobho uhlobene nobukhulu bepuleti, ngobubanzi obumaphakathi obungaba yisigamu sobukhulu bepuleti.
Izimbobo ezimbobo zamapuleti amakhulu zikhulu futhi zinesimo esingesiyindilinga, okuholela ekuqhekekeni okukhulu.
Akufanele izingxenye ezinezidingo eziphezulu zokunemba komshini, ngokuvamile zisetshenziselwa udoti noma izindawo ezingezona ezibalulekile.
Ingcindezi ye-oxygen esetshenziswa ekubhobozeni iyafana naleyo esetshenziswa ekusikeni.
2, Ukuhlaziywa kokuguquguquka kwemigodi emincane ekusikeni nasekucutshungulweni
Le nkinga ivame ukwenzeka lapho imishini yokusika nge-laser enamandla amakhulu icubungula izimbobo ezincane ezinobubanzi obuncane kunobukhulu bepuleti.
Ukuhlaziywa kwembangela: Uma ithuluzi lomshini lisebenzisa ukubhoboza kwe-pulse (ukubhoboza okuthambile) lapho kucutshungulwa imigodi emincane, amandla e-laser agxile kakhulu endaweni encane, okwenza indawo engacutshungulwa ishiswe, okuholela ekuguqukeni kwesimo sembobo futhi kuthinte ikhwalithi yokucubungula.
Isixazululo:
Umshini we-laser onamandla amakhulu: Shintsha ukubhoboka kwe-pulse (ukubhoboka okuthambile) kube ukubhoboka okuqhumayo (ukubhoboka okuvamile) ohlelweni lokucubungula.
Umshini we-laser onamandla aphansi: Ngokuphambene nalokho, ukubhoboza kwe-pulse kufanele kusetshenziswe ukuze kufezwe ukushelela okungcono kwendawo.
3、 Isixazululo sama-burrs ezintweni zokusebenza ngesikhathi sokusika nge-laser kwensimbi ephansi kwekhabhoni
Ngokusho komgomo wokusebenza wokusika nge-laser, izimbangela eziyinhloko kanye nezinyathelo zokulwa nama-burrs yilezi ezilandelayo:
Indawo yokugxila engalungile: Yenza ukuhlolwa kwendawo yokugxila bese ulungisa izindawo zokuya phezulu naphansi ngokusekelwe ku-offset.
Amandla okukhipha i-laser anganele: Hlola ukuthi ijeneretha ye-laser isebenza kahle yini; Uma ijwayelekile, hlola inani lokukhipha lenkinobho yokulawula bese ulilungisa ngokufanele.
Ukunciphisa ijubane lomugqa kuhamba kancane kakhulu: Khulisa ijubane lomugqa ngokufanele ekulawuleni ukusebenza.
Ukungahlanzeki ngokwanele kwegesi yokusika: Nikeza igesi yokusebenza yokusika esezingeni eliphezulu.
Ukulungiswa kokugxila nge-laser: Hlola kabusha bese ulungisa indawo yokugxila.
Ukusebenza okungazinzile kwethuluzi lomshini: Uma ithuluzi lomshini lisebenza isikhathi eside kakhulu futhi lingazinzile, kudingeka livalwe bese liqalwa kabusha.
4, Ukuhlaziywa kwama-burrs enziwe ngezinto zokusebenza akhiqizwa ngesikhathi sokusika nge-laser amapuleti ensimbi engagqwali kanye ne-aluminium zinc ambozwe nge-aluminium
Ubunzima: Uma kuvela ama-burrs ezintweni ezinjalo, akukwazi ukuxazululwa kalula ngokwandisa isivinini sokusika, njengoba isivinini esisheshayo kakhulu singabangela ukuthi kube nzima ukusisika ishidi, ikakhulukazi lapho kucutshungulwa amashidi ambozwe nge-aluminium zinc.
Isixazululo: Kuyadingeka ukucabangela ngokuphelele ezinye izici zethuluzi lomshini, njengokuhlola ukuthi i-nozzle idinga ukushintshwa nokuthi ukunyakaza kwesitimela esiqondisayo kuzinzile yini, nokwenza uphenyo oluhlelekile nokulungiswa.
5, Ukuhlaziywa kokusikwa kwe-laser okungaphelele ngesimo
Izizathu eziyinhloko zokucubungula okungazinzile okuholela ekusikeni okungaphelele zifaka:
Ukukhetha umlomo ongafanele: Ukukhetha umlomo wekhanda le-laser akufani nobukhulu bepuleti lokucubungula.
Ukunciphisa isivinini ngokushesha kakhulu: Kudingeka ukulawula nokunciphisa isivinini somugqa.
Iphutha elikhulu endaweni yokugxila: Ukuzwa kwe-nozzle okungalungile kuholela ekuphambukeni ngokweqile endaweni yokugxila nge-laser, okudinga ukuhlolwa kabusha kwedatha yokuzwa kwe-nozzle (le nkinga kungenzeka kakhulu lapho kusikwa i-aluminium).
6, Isixazululo sezinhlansi ezingavamile lapho kusikwa insimbi enekhabhoni ephansi
Izinhlansi ezingavamile zingathinta ukushelela kobuso bokusika bezingxenye. Uma ezinye izilinganiso zijwayelekile, izici ezilandelayo kufanele zihlolwe:
Ukuguguleka kwe-nozzle: I-nozzle yekhanda le-laser (i-NOZZEL) igugulekile futhi kufanele ishintshwe ngesikhathi esifanele. Uma kungekho -nozzle entsha, ingcindezi yegesi yokusika ingakhushulwa okwesikhashana.
Ukuxhumeka okuxegayo: Intambo ekuxhumaneni phakathi kwe-nozzle nekhanda le-laser ixegayo. Kuleli qophelo, ukusika kufanele kumiswe ngokushesha, isimo sokuxhumeka kwekhanda le-laser kufanele sihlolwe, futhi izintambo kufanele ziqiniswe futhi.
