Umbiko obukhoma: Ukumbozwa nge-laser odongeni lwangaphakathi lwembobo yephini ye-bracket yeplanethi, kufakazelwa ubuciko bokuvuselelwa kwezimboni

Ngo-7:30 ekuseni, ithimba lethu lobuchwepheshe ladlula ekhonkrithini emanzi efektri lapaka phambi kwendawo yokusebenzela imishini enzima yamakhasimende. Namuhla, besifaka i-laser cladding odongeni olungaphakathi lwembobo yephini ukuze kube yingxenye ebalulekile yemishini—uhlaka lweplanethi.

Umoya we-workshop wawuphethe iphunga elihlukile loketshezi lokusika insimbi kanye namafutha enjini, kuyilapho izintambo ze-crane zilenga buthule phezulu. "Isiguli" sethu - isigaba seplanethi esinesisindo samathani amaningana - sasihlanzwe ngokucophelela futhi safakwa ngokuphephile epulatifomu enkulu yokubamba umsebenzi. Njengesiqhwaga esithule, izindonga zaso zangaphakathi zazinezimbobo zephini ezibangelwa ukuguguleka ezivulekile kakhulu, "amanxeba" esasizowaphatha ngokunemba namuhla.

Uphenyo lwendawo kanye "nokulungiselela ngaphambi kokuhlinzwa"

Unjiniyela uWang ohlangothini lweklayenti weza kithi. Lapho exhawulana ngezandla, ubulukhuni namandla entendeni yesandla sakhe kwakubonakala. Ngaphandle kwemithetho, wakhomba ngqo emgodini omkhulu we-bearing bushing: "Lona usugugile ngo-0.8mm, okubangela imisindo engavamile kuyo yonke inhlangano yokudlulisa. Uma siqhubeka nokuwusebenzisa, uzosuswa." Iphimbo lakhe laliphethe kokubili usizi lwengxenye eyinhloko ebizayo esondela ekuhlulekeni kanye nokulindela inqubo yethu entsha.

Ngagoba phansi ngafaka ithoshi emgodini. Lapho ukukhanya kwakulandela khona indlela yalo, ngangibona ngokucacile imihuzuko engabonakali kanye nokuphambuka okuncane kodonga lwangaphakathi okubangelwa ukuguguleka okuncane. Uhlaka lwamaplanethi lwalulukhulu, kodwa inselele yayisekuqondeni kobuso obungaphakathi obulinganiswe ngama-micrometer—okufana nokuqopha amaphethini ayinkimbinkimbi enkundleni yebhasikidi, okudinga ukunemba okuphelele kanye nokuzinza.” Ungakhathazeki, Unjiniyela Wang. Ukumbozwa nge-laser kwadalelwa le njongo,” ngisho, ngisukuma ukuze ngimise “itafula lethu lokusebenza.”

Ukuvula ibhokisi lemishini kwembulwe ingxenye eyinhloko—ikhanda elingaphakathi le-laser elifakwe uphuphu olufakwe udongeni. Umklamo walo omncane, osezingeni lokuhlinzwa wawufana nethuluzi elinembile elilungele ukusebenza ngaphakathi kohlaka lweplanethi. Lapho uzakwabo uXiao Zhang evula uhlelo oluhlanganisiwe, i-laser eyisikwele ikhipha umsindo ophansi njengoba isikrini sekhabhinethi yokulawula sikhanya ngamapharamitha ashintshashintshayo. Sixhume amapayipi okupholisa ngendlela ehlelekile, safaka amakhethini egesi avikelayo e-coaxial, salungisa izindlela zokukhanya, futhi salungisa kahle i-powder feeder—isinyathelo ngasinye senziwa ngokucophelela okukhulu. Umoya wawugcwele umsindo onesigqi wabalandeli kanye nemiyalo yethu emifushane.

Inqubo yokufaka i-cladding: umdanso wokukhanya kanye ne-powder

"Inqubo" yangempela yaqala. Iqondiswa yizindlela ezihlelwe kusengaphambili, ikhanda lokumboza lafakwa ngobumnene emgodini wephini lohlaka lweplanethi. Ngaphakathi kokujula okufiphele kwembobo, umsebe we-laser ongabonakali emehlweni angenalutho ugxile ngokunemba odongeni lwangaphakathi, wakha ngokushesha ichibi elincibilikisiwe elincane. Cishe ngesikhathi esifanayo, igesi elithwalayo lakhipha i-ultra-fine nickel-based alloy powder nge-nozzle yekhanda lokumboza, lifafaza ngokulinganayo njengenkungu nothuli oluletha ngqo izinto echibini elincibilikisiwe.

Ngokuphazima kweso, i-powder kanye nensimbi eyisisekelo kwancibilika ngokushesha, kwaxubana, futhi kwaqina ngaphansi kwamandla amakhulu e-laser. Ngefasitela lokubuka, ichibi elincane elincibilikisiwe lakhanya ngokukhanya okumhlophe okufiphazayo, liqhubeka kancane kancane lakha ungqimba oluqinile, olubushelelezi, noluboshwe ngensimbi ngemuva kwalo. Lesi simo sasifana nokusebenzisa ukukhanya njengebhulashi ukudweba inethiwekhi entsha yensimbi ngaphakathi kwengaphakathi lensimbi.

"Izinga lokugeleza kwempuphu lihlala lizinzile, amandla e-laser ahlala ngaphakathi kwemingcele evamile, kanti ichibi elincibilikisiwe ligcina isimo esiphelele." UXiao Zhang wagcina amehlo akhe egxile esikrinini sokuqapha, enikeza izibuyekezo zesikhathi sangempela 'ngezimpawu zokuphila'. Ngimi ngiqopha yonke ipharamitha, ngiqinisekisa ukuthi yonke imizuzu yalokhu 'kuhlinzwa okungenangozi kakhulu' ihlala ilawulwa. Onjiniyela abambalwa abasebasha ohlangothini lweklayenti babuthana nxazonke, amehlo abo anomdlandla egxile endaweni yokushisa ehambayo esikrinini njengoba behlebelana bodwa. Unjiniyela uWang wema egoqe izingalo, ubuso bakhe buncipha kancane kancane kusukela ekudonseleni amandla okuqala kuya ekuziphatheni okukhululekile.

Ubuciko nokuzibophezela

Yonke inqubo yokumboza yathatha cishe amahora amane. Lapho ikhanda lokumboza liphuma kancane kancane emgodini wokugcina, sacisha imishini futhi indawo yokusebenzela yathula. Kodwa umsebenzi wawungakapheli. Isinyathelo esibaluleke kakhulu kwakuwukuhlola.

Ngithathe ithoshi kanye ne-endoscope, ngakufaka emgodini. Ngaphansi kokukhanya, ungqimba olusha olubekwe lubonise ukukhanya kwensimbi okufanayo, okufana "nehembe elisha" elilungiselelwe kahle elifakwe kahle odongeni lwangaphakathi olugugile. Abahloli bokurhabaxa abaphathekayo baqinisekisile inani le-Ra elingaphansi kuka-0.8μm, kuyilapho izilinganiso zobukhulu bamaphuzu amaningi zisebenzisa igeyiji ziveze ubukhulu obuhambisanayo kulo lonke ubuso, zihlangabezana ngokugcwele nemininingwane yokubekezelelana engu-0.5±0.05mm echazwe emidwebweni yobunjiniyela. "Unjiniyela uWang, njengoba ubona," ngidlulise idatha yokulinganisa, "ungqimba lwe-cladding kanye ne-substrate kuhlanganiswe ngensimbi, ngamandla adlula ngisho nezinto eziyisisekelo. Ngokuphathelene nenkinga yokuguquguquka kokushisa okhathazeke kakhulu ngayo, ukulawula kwethu inqubo kuqinisekisa ukuthi ukuguqulwa okuphelele kuhlala kungaphansi kuka-0.03mm. Lokhu kuqeda isidingo somshini osindayo, okuvumela ukuhlanganiswa okuqondile ngemva kokugaya ngokunemba."

UMnu. Wang wathatha umbiko, ehlola yonke imitha ngokucophelela ngaphambi kokuhlola mathupha i-endoscope isikhathi eside. Ekugcineni waqonda, ubuso bakhe buqala ukumamatheka kwangempela kosuku: "Kuhle kakhulu! Lo mphumela udlula konke okulindelwe. 'Umgogodla' wethu uvuselelwe ngokuphelele - uzohlala okungenani omunye umjikelezo ogcwele wokusebenza!" La mazwi abe yisikhumbuzo sokugcina semizamo yeqembu lethu engakhathali. Njengoba ehlela amathuluzi, imisebe yegolide yokushona kwelanga yangena esibhakabhakeni se-workshop, ikhipha ukukhanya okufudumele phezu kwemishini yensimbi ebandayo. Emi phambi kohlaka lweplanethi olwaluthole "ukuvuselelwa" kwethu, umuzwa ojulile wokufeza wagcwala ngaphakathi kuye.

Lokho esikunikezayo kudlulela ngale komshini obandayo noma ubuchwepheshe obusezingeni eliphezulu – kuhlanganisa ukuvikela izimpahla zamakhasimende nokuhlonipha ubuciko ngokuzibophezela okungapheli. Lapho i-laser ivala futhi imishini ipakishwa, sihamba namathuluzi, kodwa sishiya ifa lokuthembeka nokwethenjwa okuhlanganiswe ezinqubweni zokukhiqiza zamakhasimende ethu. Lokhu kanye okuyisisekelo kuqhuba ukuzinikela kwethu kwansuku zonke kuyo yonke indawo yokukhiqiza esiyivakashelayo.
