Ingxelo ebukhoma: Ukugqunywa nge-laser eludongeni olungaphakathi lomngxuma wephini yesibiyeli seplanethi, kungqina ubugcisa bokulungiswa kwemizi-mveliso

Ngentsimbi yesi-7:30 kusasa, iqela lethu lobuchwephesha ladlula kwikhonkrithi emanzi yomzi-mveliso laza lapaka phambi kwendawo yokusebenzela enzima yomatshini yomthengi. Namhlanje, besisenza i-laser cladding eludongeni olungaphakathi lomngxuma wephini ukuze kubekho into ebalulekileyo kwisixhobo—isakhelo seplanethi.

Umoya we-workshop wawuphethe ivumba elikhethekileyo lolwelo lokusika isinyithi kunye neoyile yenjini, ngelixa iintambo ze-crane zixhonywe ngokuzolileyo ngaphezulu. "Isigulana" sethu - inqanaba leplanethi elinobunzima beetoni ezininzi - sasicociwe ngononophelo kwaye sifakwe ngokukhuselekileyo kwiqonga elikhulu lokugcina umsebenzi. Njengesigebenga esingathethiyo, iindonga zaso zangaphakathi zazinemingxuma yentsimbi egugileyo enesithuba esigqithisileyo, "amanxeba" esasiza kuwanyanga ngokuchanekileyo namhlanje.

Uphando oluqhubekayo kwindawo kunye "nokulungiselela ngaphambi kotyando"

Unjineli uWang owayekwicala lomthengi weza kuthi. Xa wayexhawulana ngezandla, uburhabaxa kunye namandla entendeni yakhe kwakubonakala. Ngaphandle kwemigaqo, wakhomba ngqo kumngxuma omkhulu we-bearing bushing: "Le igugile nge-0.8mm, nto leyo ebangela ingxolo engaqhelekanga kuyo yonke i-transmission assembly. Ukuba siqhubeka siyisebenzisa, iza kucinywa." Ithoni yakhe yayithwele intlungu yecandelo eliphambili elibizayo elisondela ekusileleni kunye nolindelo lwenkqubo yethu entsha.

Ndagoba ndaza ndafaka itotshi emngxunyeni. Apho ukukhanya kwakulandela khona indlela yayo, ndayibona ngokucacileyo imikrwelo engabonakaliyo kunye nokugqwetheka okuncinci kodonga lwangaphakathi okubangelwa kukuguguleka okuncinci. Isakhelo seplanethi sasisikhulu, kodwa umngeni wawukuchaneka komphezulu wangaphakathi olinganiswe ngee-micrometers—njengokuzoba iipateni ezintsonkothileyo kwibala lebhasikithi, kufuna ukuchaneka okupheleleyo kunye nokuzinza.” Ungakhathazeki, Njineli uWang. I-laser cladding yenzelwe le njongo kanye,” ndatsho, ndisukuma ukuze ndimise “itafile yethu yokusebenza.”

Ukuvula ibhokisi yezixhobo kwabonakala icandelo eliphambili—intloko yelaser efakwe umgubo eludongeni lwangaphakathi. Uyilo lwayo olubhityileyo nolukumgangatho wotyando lwalufana nesixhobo esichanekileyo esilungele ukusebenza ngaphakathi kwisakhelo seplanethi. Xa umlingani uXiao Zhang wavula inkqubo edibeneyo, ilaser enesimo sesikwere yakhupha isandi esiphantsi njengoko isikrini sekhabhinethi yokulawula sasikhanya ngeeparameter ezitshintshatshintshayo. Sidibanise imibhobho yokupholisa ngendlela ecwangcisiweyo, safaka amakhethini egesi akhuselayo e-coaxial, salungisa iindlela ze-optical, saza salungisa i-powder feeder—inyathelo ngalinye lenziwa ngononophelo olucokisekileyo. Umoya wawuzaliswe kuphela yisandi esinesingqisho seefeni kunye nemiyalelo yethu emfutshane.

Inkqubo yokufaka i-cladding: umdaniso wokukhanya kunye nomgubo

"Inkqubo" yokwenyani yaqala. Ikhokelwa ziindlela ezicwangcisiweyo kwangaphambili, intloko ye-cladding yafakwa ngobunono kumngxuma we-planetary frame pin. Ngaphakathi kobunzulu obufipheleyo be-bore, umqadi we-laser ongabonakaliyo emehlweni ongakhange ubonakale ugxile ngokuchanekileyo eludongeni lwangaphakathi, ngoko nangoko wenza idama elinyibilikisiweyo elinomfanekiso omncinci. Phantse ngaxeshanye, igesi ethwalayo yaqhuba umgubo we-alloy osekelwe kwi-nickel ocolekileyo kakhulu nge-nozzle yentloko ye-cladding, itshiza ngokulinganayo njengenkungu nothuli oluhambisa ngokuchanekileyo izinto kwidama elinyibilikisiweyo.

Ngephanyazo, umgubo kunye nesinyithi esisisiseko zanyibilika ngokukhawuleza, zaxutywa, zaza zaqina phantsi kwamandla amakhulu elaser. Ngefestile yokujonga, ichibi elincinci elinyibilikisiweyo lalikhanya ngokukhanya okumhlophe okungaboniyo, liqhubeka lisiya phambili ukwenza umaleko oxineneyo, ogudileyo, nodibeneyo ngesinyithi emva kwalo. Lo mbono wawufana nokusebenzisa ukukhanya njengebhrashi ukuzoba inethiwekhi entsha yesinyithi ngaphakathi komngxuma wangaphakathi wesinyithi.

"Izinga lokuhamba komgubo lihlala lizinzile, amandla elaser ahlala ngaphakathi kwemilinganiselo eqhelekileyo, kwaye ichibi elinyibilikisiweyo ligcina imo egqibeleleyo." UXiao Zhang wagcina amehlo akhe ethe ntsho kwisikrini sokujonga, enika uhlaziyo lwangempela 'kwiimpawu zobomi'. Ndema ndirekhoda yonke iparameter, ndiqinisekisa ukuba yonke imzuzu yale 'tyando olungenamsebenzi kangako' ihlala ilawulwa. Iinjineli ezimbalwa eziselula ezivela kwicala lomthengi zaqokelelana, amehlo azo anomdla ejonge kwindawo yobushushu ehambayo kwiscreen njengoko babehlebeza phakathi kwabo. Unjineli uWang wema egobile iingalo, ubuso bakhe buqala ukusuka kumxhuzulane ukuya kwisimo sengqondo esikhululekileyo.

Ubuchule bobugcisa kunye nokuzinikela

Yonke inkqubo yokugquma ithathe phantse iiyure ezine. Xa intloko yokugquma iphuma kancinci kancinci emngxunyeni wokugqibela, sacima izixhobo kwaye indawo yokusebenzela yathula. Kodwa umsebenzi wawungekapheli. Inyathelo elibaluleke kakhulu yayikukuhlola.

Ndithathe ithotshi kunye ne-endoscope, ndazifaka emngxunyeni. Phantsi kokukhanya, i-coating entsha efakweyo yayibonisa ukukhanya kwesinyithi okufanayo, okufana "nehempe entsha" elungiselelwe ngokugqibeleleyo efakwe kakuhle eludongeni lwangaphakathi olugugileyo. Abavavanyi boburhabaxa obuphathekayo baqinisekisile ixabiso le-Ra elingaphantsi kwe-0.8μm, ngelixa imilinganiselo yobukhulu obunamachaphaza amaninzi esebenzisa i-gauge ibonise ubukhulu obuhambelanayo kulo lonke umphezulu, ihlangabezana ngokupheleleyo neempawu zokunyamezela ze-0.5±0.05mm ezichazwe kwimizobo yobunjineli. "Injineli uWang, njengoko ubona," ndidlulisele idatha yokulinganisa, "umaleko we-cladding kunye ne-substrate zibotshelelwe nge-metallurgical, kwaye amandla adlula nesiseko. Ngokuphathelele umba wokuguqulwa kobushushu oxhalabileyo ngawo, ulawulo lwethu lwenkqubo luqinisekisa ukuba ukuguqulwa okupheleleyo kuhlala kungaphantsi kwe-0.03mm. Oku kususa isidingo somatshini onzima, okuvumela ukuhlanganiswa ngokuthe ngqo emva kokusila ngokuchanekileyo."

UMnu.Wang wathatha ingxelo, ehlolisisa yonke imilinganiselo ngononophelo olucokisekileyo ngaphambi kokuba ayihlolisise ngokwakhe i-endoscope ixesha elide. Ekugqibeleni waqonda, ubuso bakhe bubonakala buncumo lokuqala lokwenene losuku: "Kuhle kakhulu! Esi siphumo sidlula konke okulindelweyo. 'Umqolo' wethu uvuselelwe ngokupheleleyo - uza kuhlala ubuncinane omnye umjikelo opheleleyo wokusebenza!" La mazwi abe yimbeko yokugqibela kwimizamo yeqela lethu engadinwayo. Njengoko wayecwangcisa izixhobo, imitha yegolide yokutshona kwelanga yangena kwi-skylight ye-workshop, iphosa ukukhanya okufudumeleyo phezu koomatshini bentsimbi ebandayo. Emi phambi kwesakhelo seplanethi esasifumene "ukuvuselelwa" kwethu, imvakalelo enzulu yokuphumelela yagcwala ngaphakathi kuye.

Oko sikuzisayo kudlulela ngaphaya komatshini obandayo okanye iteknoloji yanamhlanje – iquka ukukhusela izinto zabathengi kunye nokuhlonipha ubuchule ngokuzinikela okungagungqiyo. Xa i-laser ivaliwe kwaye izixhobo zipakishwe, sihamba nezixhobo, kodwa sishiya ilifa lokuthembeka kunye nokuthembana okufakwe kwiinkqubo zemveliso zabathengi bethu. Le yeyona nto iqhuba ukuzinikela kwethu kwemihla ngemihla kuyo yonke indawo yokuvelisa esiyityelelayo.
