Sebenzisa umatshini wokusila oqhelekileyo we-CNC ukusetyenzwa kwesicatshulwa kwiphepha lefoyile ye-aluminium enobunzima obuyi-0.01 mm kuphela. Ukuba kukho ukuphambuka okuncinci, iphepha le-aluminium foil liya kungena okanye liphuke. Iimathiriyeli ezibhityileyo, ezithambileyo nezibhityileyo zibonwa kwihlabathi jikelele njengeengxaki zoomatshini.
Ngaphezulu kweminyaka engama-20 yesiseko soshishino oluluqilima
Wasivula kakuhle esi sixhobo
Kwaye emva koku, luhlobo luni lwebali olukhoyo?
"Umgama phakathi kweemveliso ezintle kunye nenkunkuma yi-0.01mm kuphela"
Ngo-2001, ngephupha engqondweni, uQin Shijun wangena kwi-Aviation Industry Harbin Aircraft Industry Group Co., Ltd. kwaye waba ngowona mncinci uchwepheshe we-CNC wokugaya kwinkampani kwiminyaka emine nje.
U-Qin Shijun wafunda iteknoloji ye-CNC ukususela ekuqaleni ngenxa yokuba wayenexhala lokuba uphumelele kwisikolo sobugcisa kwaye akayi kuba njengabazalwana bakhe abakhulu kunye noodadewabo malunga neediploma.
Ukuba ufuna ukwaziwa, kuya kufuneka wenze impumelelo, kwaye kuphela ngokwenza iimveliso ezigqityiweyo unokuqhawula amathandabuzo. Emva kokuba isicwangciso sokuvelisa imihla ngemihla sigqityiwe, isixhobo somatshini siba yindawo yokuvavanya yeQin Shijun. Ngaphakathi kwe-intshi yesikwere, uQin Shijun waphinda amawakawaka amaxesha.
Kwi-workshop ye-CNC, i-Qin Shijun iyona nto ijongene nokuqhutyelwa kwezixhobo zokufika kunye neengxenye ze-rotor, ezihambelana ngokuthe ngqo nokusebenza kwemveliso kunye nokhuseleko lomqhubi. Amalungu anempazamo engaphezulu kwe-0.01 mm aya kuchithwa. I-0.01 mm ilingana ne-1/10 yeenwele zomntu, ngoko uQin Shijun wayedla ngokuthi: “Umgama phakathi kwemveliso ekumgangatho ophezulu kunye nenkunkuma yi-0.01 mm kuphela.”
Emva kokusilela okungaphezu kwewaka, wenza imimangaliso
Kwi-mission, ukuchaneka komphezulu we-mating surface yenkqubo ye-gear gear yecandelo eliphambili lemodeli ethile kufuneka ibe phezulu, kwaye kuyimfuneko ukuqinisekisa ukuba ubuninzi bomhlaba bungaphezulu kwe-Ra0.4 (ubunzima bobuso).
Kangangeminyaka emininzi, olu hlobo lwendlela echanekileyo yokulungiswa komphezulu ngokusisiseko ithatha ukudika kwaye emva koko ukucola okufanelekileyo ukufezekisa ukuchaneka, okudla ixesha kunye nomthwalo kwaye kunozinzo olukumgangatho ophantsi. Xa isengozini, inqwelomoya iya kuphuka.
I-Qin Shijun idibanise idatha yembali ukuhlalutya ukuchaneka kwesixhobo somatshini, iiparamitha zokucubungula, kunye nezixhobo zokusika ukufumana isicwangciso senkqubo efanelekileyo.
Kwinyanga enye, uQin Shijun wafumana iintsilelo ezingaphezu kwewaka. Ekugqibeleni, waqaphela uburhabaxa bomphezulu bokuchaneka komatshini okruqulayo ukufikelela kwinqanaba lesipili le-Ra0.13 (uburhabaxa bobuso) ukuya ku-Ra0.18 (uburhabaxa bomhlaba), obusombulule ngokupheleleyo ingxaki ethe yathwaxa ishishini iminyaka emininzi kwaye yakha i-ra0. ummangaliso kwintsimi yokucubungula ngoomatshini, ugqithise ixabiso lomda wethiyori, uzuze i-100% yezinga lokupasa kweengxenye zokuhlolwa kwexesha elinye, kunye nokwandisa ukusebenza kakuhle malunga namaxesha amathathu.
Qin Shijun: Umda endiwufikeleleyo unokwanelisa ngokupheleleyo iimveliso zam ezicwangcisiweyo ngoku. Kodwa indlela yam inokwandiswa ekusetyenzisweni kweemveliso ezichanekileyo ze-aerospace ephezulu.
Iminyaka engama-20 yophando olunzima
Wafunga ukuba uza kuvumela abavelisi baseTshayina bathethe ngakumbi
Kule minyaka ingama-20 idlulileyo, uQin Shijun uye wakhula ukusuka kumsebenzi oqhelekileyo ukuya kwitalente yobugcisa eyaziwayo ekwenziweni kweerotors, igiya lokuhlalisa, kunye necandelo lomatshini we-CNC kwibala lezomoya kwilizwe lam kunye nengcali yobugcisa ephambili. ishishini lophapho.
Kwi-2014, i-studio ye-talented innovation i-studio ekhokelwa nguQin Shijun yasungulwa, kwaye wayekhokela iqela ukuba liphumelele ukuphumelela kwezobugcisa emva komnye. Wathi unethemba lokukhulisa ulutsha olungakumbi nokutofa igazi elitsha kwizixhobo zeenqwelo-moya, ukuze iphupha lethu lokuhamba ngeenqwelo-moya lizaliseke ngokukhawuleza, yaye ishishini lokuvelisa laseTshayina liya kuba nelizwi elingakumbi ehlabathini.
Kwisikhumbuzo seminyaka engama-70 yomkhosi womkhosi woSuku lweSizwe ngo-2019, xa inqwelo-ntaka ethathe inxaxheba kuphuhliso yabhabha phezu kweTiananmen Square, uQin Shijun wathi ngochulumanco: “Njengomsebenzi wemizi-mveliso, akukho nto inokundenza ndibone ukubaluleka komsebenzi ngaphezu koku. umzuzu. Imvakalelo yokuphumelela nokuzingca!”
Imibuliso “kwiMngcibi Welizwe Elibalaseleyo”!
