Hairpin lub cev muaj zog yog qhov kev tshawb fawb tseem ceeb ntawm lub zog hluav taws xob tshiab tam sim no. Vim hais tias ntawm nws cov super endurance, nws tau dhau los ua cov nyiam tshiab ntawm cov tuam txhab qoj nto moo. Dab tsi zoo dua cov plaub hau muaj lub cev muaj zog nrog cov tsoos lub cev muaj zog? Dab tsi yog qhov thov siv tshuab?
Lub hairpin lub cev muaj zog muaj peb lub ntsiab zoo dua li cov tsoos tooj liab hlau winding pab pawg lub cev muaj zog. Ua ntej tshaj plaws, lub qhov khoob ntawm tus nqi ntawm hairpin lub cev muaj zog yog siab. Nyob rau tib qhov chaw muaj ntau qhov chaw, thaj chaw uas muaj tooj liab tooj liab yog ntau tshaj qhov ntawd nrog tooj liab hlau, uas ua rau lub pob ntim muaj ntau lub tooj liab ntau ntxiv, yog li txhim kho kev ua haujlwm ntawm lub cev muaj zog. Thib ob, lub cev plaub hau yuav txias dua kom zoo dua vim tias nws cov menyuam ntau dua qhov sib piv thiab sib tiv tauj tag nrho ntawm cov tooj liab. Txawm li cas los xij, vim tias huab cua nyob nruab nrab ntawm cov xaim tooj liab, cov cua txias ua kom zoo dua ntawm huab cua qis dua li ntawm kev sib chwv ncaj qha, uas tsis yog qhov muaj txiaj ntsig rau qhov cua sov dissipation ntawm lub cev muaj zog. Thib peb, lub taub hau rau lub cev muaj zog yog lub zog me dua cov tooj liab hlau ua hauv qhov ntim thiab tus nqi sib tw, uas yog cov txiaj ntsig zoo dua ntxiv rau cov hnav ntawm lub cev. Vim tias qhov zoo ntawm hairpin piv nrog cov tsav ib txwm, kev tsim khoom ntawm hairpin lub cev muaj zog tau dhau los ua cov kev tshawb fawb tseem ceeb ntawm ntau lub zog lag luam tshiab nyob hauv tsev thiab txawv teb chaws.
Nyob rau tam sim no, lub ntsiab vuam cov txheej txheem ntawm hairpin sib koom tes yog arc vuam thiab laser vuam. Raws li qhia hauv daim duab, laser vuam muaj qhov zoo nyob rau ntau qhov: thawj ntawm txhua yam, hais txog qhov hloov tau yooj yim, arc vuam yuav tsum tsim cov khoom siv vuam sib txawv kom yoog tau rau ntau qhov sib txawv ntawm lub cev, thaum laser vuam tuaj yeem siv txoj kev pom kev, tsuas yog xav tau hloov pauv cov phiaj xwm; qhov thib ob, laser vuam yog qhov ruaj khov dua li arc vuam, thiab cov txheej txheem vuam ruaj khov yog li 2 hli qhov tob ntawm tooj liab cov khoom siv yog qhov zoo heev, tab sis tom qab ntau tshaj 2 hli, vuam tsis ruaj khov thiab lub tshav kub nkag yog loj, thiab cov laser vuam tuaj yeem sib zog dua li cov arc vuam, thiab cov lus nkag hauv kub muaj tsawg dua; qhov thib peb, txoj kab txuas ntawm ob txheej txheem tsis txawv, tab sis saum npoo ntawm laser vuam yuav yooj yim dua; plaub, cov ntsiab lus cua sov ntau dua ntawm arc vuam yuav ua rau tawg, thiab nws yog ib qho yooj yim uas ua rau lub vuam tsis xws luag; tsib, kev teeb tsa Nyob rau hauv nqe lus ntawm seem poob, arc vuam cov txheej txheem xav kom phim cov khoom siv vuam sib txawv rau qhov sib txawv lub cev muaj zog, thaum laser vuam tsuas yog xav hloov lub khob tiv thaiv; thib tsib, qhov sib txawv ntawm vuam yeej ntawm ob qho txheej txheem tsis yog loj, tab sis lub sijhawm hloov khoom siv tau muaj txiaj ntsig ntau dua; thib rau, hais txog cov nqi, tus nqi ntawm arc vuam cov cuab yeej tsuas yog muaj kwv yees li ib feem tsib ntawm cov nqi ntawm cov khoom siv laser, thiab nws yog qhov zoo siab Optical workstation xav tau kev tiv thaiv tshwj xeeb laser, thiab kev cob qhia cov neeg ua haujlwm yog qhov nyuaj dua arc vuam.
Daim ntawv thov ntawm laser welding nyob rau hauv hairpin lub cev muaj zog
Laser welding hauv tooj liab vuam, thawj qhov kev xav yog cov khoom siv rau qhov nqus laser. Thaum 1060nm (CO2 laser) laser wavelength, qhov nqus tus nqi ntawm tooj liab rau laser tsuas yog li 10%. Hauv qhov ntau ntawm laser laser ntev ntev ntawm 500nm, qhov nqus ntawm tooj mus rau laser yog qhov siab dua, thiab cov thev naus laus zis tsis tuaj yeem nkag mus tob tob. Txawm li cas los xij, thaum tooj liab nyob hauv lub xeev melting, qhov nqus ntawm laser tuaj yeem ncav cuag qhov siab dua, yog li siv cov khoom siv hluav taws xob muaj zog-lub xeev laser kom ua tiav lub qhov tawg tawg tuaj yeem ua rau laser vuam tooj liab tau.
Tam sim no, txoj kev sib koom tes ntawm laser vuam yog siv cov taub hau laser kom phim rau cov cim kom pom tseeb lub zog. Lub taub hau laser yuav tsum yog lub kaw lus galvanometer nrog ob qhov ntev ntawm X thiab y, uas tuaj yeem paub txog cov vuam khiav ntawm ntau cov duab ntawm vuam dav hlau. Tsis tas li ntawd, nws tseem yuav tsum muaj qhov muaj peev xwm ntau qhov oscillation muaj nuj nqi, uas tuaj yeem nplawm lub pas dej nyob rau hauv lub vuam txheej txheem, uas yog qhov tsim nyog rau cov roj tawm hauv qhov dej pas nrig thiab ua kom zoo dua vuam zoo. Lub zeem muag pom kev tsim kho yuav tsum muaj peev xwm paub txog cov duab ntawm ntau cov leeg txuas pob txha, thiab kuj yuav tsum muaj qee qhov tsis ua yuam kev tsis haum.
