Lapho abantu abaningi bezwa 'ukwenziwa kwensimbi', babona ngeso lengqondo indoda ishisela izingcezu ezimbili zensimbi ndawonye. Lokho kuyingxenye yakho, impela, kodwa kufana nokuthi ukupheka kuwukuxova ibhodwe. Indaba yangempela iqala ngaphambi kokuba kundiza izinhlansi, ngokukhethwa kwezinto kanye nendlela yokuyilolonga. Ngibone amaphrojekthi amaningi kakhulu elengiswa ngenxa yokuthi othile ucacise 'insimbi' evamile emdwebeni wengxenye edinga ukumelana nesifutho sikasawoti esihlala njalo, noma wayala ijiyomethri eyinkimbinkimbi ngenqubo yokwakheka engalungile, eshaya isabelomali. Ukwakhiwa kuyisenzo sokugcina; umdlalo ubhalwe endaweni yokusungula kanye nesitolo semishini.
Isisekelo: Iqala ngabalingisi
Awukwazi ukwenza lokho ongenakho. Umsebenzi wethu omningi uqala ngokulingisa okungahluziwe. Yilapho izinkampani ezinolwazi olujulile lwempahla, njenge-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ziba ozakwethu ababalulekile. Sebeneminyaka engaphezu kwengu-30 besemdlalweni wokulingisa nokwenza imishini, okusho ukuthi sebebonile ukuthi yini esebenzayo nehlulekayo. Uma bekhuluma ukubunjwa kwegobolondo ukuze uthole indawo engcono yokuqeda phezu kwendlu yepompo noma ukutshala imali kuleyo blade ye-turbine eyinkimbinkimbi eneziteshi zangaphakathi, uyalalela. Akuyona nje inkulumo yokuthengisa; isekelwe emashumini eminyaka okuthulula insimbi.
I-Material spec ingenye inkundla yemigodi. Insimbi engagqwali ayiyona into eyodwa. Ingabe i-304 yokumelana nokugqwala okujwayelekile, noma i-316 yama-chlorides? Noma sikhuluma nge-alloy esekelwe ku-nickel yezinhlelo zokusebenza ezishisa kakhulu? Ngikhumbula umsebenzi weklayenti lokucubungula amakhemikhali lapho ekuqaleni sasebenzisa indwangu evamile ye-304. Kuphumelele zonke izivivinyo zokuqala, kodwa phakathi nezinyanga eziyisithupha ensimini, saqala ukubona ukugqwala kwengcindezi kuqhekeka kumajoyinti okushisela. Imvelo inama-trace chloride esingazange siwabale. Kudingeke ukuthi siphinde sakhe umhlangano wonke sisebenzisa i-316L. Lelo phutha laliyisifundo esinonya kwisayensi yezinto ezibonakalayo ukuthi ayinakuxoxiswa. Okuhlangenwe nakho kwe-QSY ngama-alloys akhethekile afana ne-cobalt kanye ne-nickel-based kuwuphawu abaluqondayo lezi zindawo eziphakeme kakhulu.
Ukuthola abalingisi abalungile kungu-70% wempi. Ukufakwa kwesango okunesango elingalungile okunokuncipha kwangaphakathi noma ukujiya kodonga okungahambisani kushintsha okulandelayo ukwenziwa kwensimbi inqubo ibe yiphupho elibi lokungqubuzana ngesikhathi sokushisela noma ukubekezelelana kwemishini okungenakwenzeka. Uzakwethu omuhle we-Foundry uletha ingxenye yomumo oseduze nenetha engenziwa ngokoqobo.
I-CNC Machining: I-Precision Interlude
Manje, ukulingwa kuyafika. Ayivamisile ukuthi ilungele ukubhawulwa. Yilapho imishini ye-CNC ingena khona ukwenziwa kwensimbi ukuhamba komsebenzi. Ukubhoboza amaphethini webhawodi, izindawo ezibheke phezulu, ukudala imisele yokuvala—lona umsebenzi oqondile ochaza ukuthi umhlangano wokugcina ungena kahle kangakanani. I-QSY ihlanganisa lokhu, okuyinzuzo enkulu. Kusho ukuthi ithimba elifanayo eliqonda ukwakheka kokusanhlamvu okusanhlamvu kanye nezindawo zokucindezelwa ezingaba khona nalo lenza umshini. Bayazi ukuthi bangagwema kuphi ukuthatha ukusikeka okunzima kakhulu odongeni oluncane, noma ukuthi bangalungisa kanjani ukufakwa kwezimali okumise okwenqaba ngaphandle kokukuhlanekezela.
Ngifunde kabuhlungu ukuthi ukuhlukanisa abathengisi be-casting kanye nemishini kungaholela emdlalweni wokusola. Umakhi wemishini uthi ukulingisa kuthambile noma kuyanyakaza, umsunguli uthi umakhi usebenzisa isivinini/izifunzo ezingalungile. Ukuba nayo ngaphansi kophahla olulodwa, njengasendaweni yabo (ungabona indlela yabo ku- https://www.tsingtaocnc.com), kuyakuqeda lokho. Iluphu yempendulo iyashesha. Uma ithuluzi likhuluma kuqoqo elithile le-alloy, lingakwazi ukulungisa amapharamitha womshini noma lize lihlabe umkhosi libuyisele kunqubo yokuncibilika. Lokhu kubumbana kuyinto okujabulelayo kuphela ngemva kokubhekana nokunye.
Umgomo wokwenza imishini ekulungiseleleni ukwenziwa akukhona nje ukushaya ubukhulu kokuphrintiwe. Okokudala izindawo eziyisethenjwa nezici ezizovumela umenzi ukuthi ahlanganise izingxenye ngokubikezela. Iphutha eliyinkulungwane le-intshi ekukhwezweni komlenze owenziwe ngomshini lingahumushela ekungalungisweni kahle kwekota-intshi uma uzama ukushisela uhlaka olukhulu.
Isitezi Sokwenziwa: Lapho Ithiyori Ihlangana Nethoshi
Lena ingxenye engcolile, enomsindo futhi ekhazimulayo. Unokulingisa kwakho komshini, ipuleti lakho elisikiwe, isitoko sakho sebha. Manje konke kufanele kuhlangane. Ukushisela i-nickel-based alloy kuyisilwane esihlukile kunensimbi yokushisela ethambile. Okokufaka ukushisa, izinga lokushisa le-interpass, insimbi yokugcwalisa—kuyiresiphi. Kwenze kungalungile, futhi unyusa ama-carbides endaweni ethinteke ukushisa, ayenze ibe brittle. Kwake kwadingeka ukuthi sishisele umkhono we-cobalt alloy sibe yindlu yensimbi. Ukwandiswa kokushisa okuhlukile kukodwa kwakuyikhanda elibuhlungu. Ukushisa kwangaphambili, ukulandelana kwe-weld ethile, ukupholisa phansi okulawulwayo... kwakufana kakhulu nokuhlolwa kwamakhemikhali.
I-Jigging kanye ne-fixturing amaqhawe angaculwa. Ngomsebenzi wokwakha ophindayo, isikhathi esichithwe ekwakheni ijigi eqinile, elungisekayo siyazikhokhela izikhathi eziyishumi. Kodwa kuma-off-off noma ama-prototypes, uvame ukwenza ngcono ngezinsimbi, omagnethi, kanye nama-tack weld wesikhashana. Iqhinga liwukwazi ukuthi i-tack yesikhashana izodala nini ingcindezi eyanele ukuze ikhiphe yonke inhlangano esikweleni. Kwesinye isikhathi kufanele uyiyeke inyakaze, bese uyilungisa, kunokuba ulwe nokuyisa.
Ukulawula ukuhlanekezela. Leyo yimpi eqhubekayo. Ufaka ukushisa okukhulu, okwenziwe kwasendaweni ukuze uhlanganise izinsimbi, futhi zifuna ukunyakaza. Ukulandelana kwama-welds kubalulekile. Kupulangwe ende enama-stiffener amaningi, ungase uthunge i-weld ngephethini ethile, ugxuma usuka kolunye uhlangothi uye kolunye, ukuze ulinganise ukudonsa. Kwesinye isikhathi uze ugobe izingxenye zangaphambili zibheke kolunye uhlangothi, ulindele ukudonsa kwe-weld. Akuyona isayensi eqondile; umuzwa kanye nesipiliyoni.
Ikhwalithi: Izinyathelo Ezingabonakali
Ukwenziwa akwenziwa lapho kubekwa ubuhlalu bokugcina be-weld. Yilapho-ke ukuhlola kuqala. Ukuhlola okubonakalayo kuqala-ukufuna imifantu, i-undercut, i-porosity. Bese kuza imihlola engacekeli phansi. Udayi ongenela amaphutha angaphezulu kulawo mashisela angenabala noma ingxubevange. Mhlawumbe ukuhlolwa kwe-ultrasonic kokulimala kwangaphakathi ezigabeni eziwugqinsi. Ngokwakhiwa okuqukethe ingcindezi, ukuhlolwa kwe-hydrostatic kuyadingeka.
Kodwa enye yezinyathelo ezibaluleke kakhulu, futhi evame ukunganakwa, i-post-weld heat treatment (PWHT). Ezinsimbi eziningi ze-alloy futhi ikakhulukazi ezakhiwe ngezingxenye ezisindayo, i-PWHT ibalulekile ukukhulula izingcindezi eziyinsalela ezivalelwe ngenxa yokushisela. Kuyinqubo edla isikhathi namandla—ukunamathisela wonke umhlangano kuhhavini omkhulu futhi ulethe ezingeni lokushisa elithile ngesikhathi esithile. Kuyalinga ukuyeqa ukuze uhlangabezane nomnqamulajuqu, kodwa ngibone imiphumela: i-baseplate enkulu eyenziwe nge-compressor eyaqhekeka ngokuzwakalayo ezinyangeni kamuva ihlezi egcekeni, isuka ekucindezelekeni kwangaphakathi izama ukulinganisa.
Amadokhumenti ayingxenye yekhwalithi futhi. Irekhodi elifanele lokwenziwa, elinezitifiketi zezinto ezibonakalayo, ukucaciswa kwenqubo ye-weld (WPS) esetshenzisiwe, amashadi okwelashwa kokushisa, nemibiko yokuhlola, yikhona okuphendulela inqwaba yensimbi ibe ingxenye elandelekayo, ethembekile. Yilapho ukusebenzisana nomhlinzeki ohlanganiswe mpo okubonisa khona inani lakho futhi. Izitifiketi zezinto ezibonakalayo ezivela ekulingiseni, imibiko yomshini, namarekhodi okwenziwa konke kungaba yingxenye yephakheji ehambisanayo.
Inzuzo Ehlanganisiwe
Ngakho, ukuzungeza emuva. Iqiniso ukwenziwa kwensimbi akulona uhwebo olulodwa. Isiphetho seketango: ukukhethwa kwempahla, ukwakha (njengokubukisa), ukwenziwa kwemishini enembile, futhi ekugcineni, ukuhlanganisa nokuqeda. Uma lezi zigaba zithululwa, ulahlekelwa ulwazi. Umkhiqizi akazi ukuthi kungani indawo ethile yokusakaza inzima, umshini wemishini akaqondi ukulandelana kwe-weld okuzolandela.
Kungakho imodeli yenkampani efana ne-QSY ithakazelisa. Ukusebenza iminyaka engaphezu kwengu-30 ekulingiseni nasekukhiqizeni imishini kubanikeza ukuqonda okuyisisekelo kokuziphatha kwendawo kusukela esimweni sayo soketshezi kuye phambili. Uma bese behlanganyela noma benikezela ngezinto zokwakha, baletha wonke lowo mlando etafuleni. Abagcini ngokuthengisa i-casting noma ibhulokhi eyenziwe ngomshini; bathengisa ingxenye enezici ezaziwayo, ukuziphatha okungabikezelwa ngaphansi kwethoshi, kanye nengozi encishisiwe yezimanga eziya phansi.
Kunjiniyela noma umphathi wephrojekthi, lokhu kuhlanganiswa kuyithuluzi lokunciphisa ubungozi. Yenza lula uchungechunge lokuhlinzeka, iqinise i-loop yempendulo yokuxazulula izinkinga, futhi yakhela ngokwemvelo ekuhlolweni kwekhwalithi ezigabeni ezengeziwe. Umgomo wokugcina wokwenziwa akukhona nje ukwenza okuthile okufana nomdwebo. Kuwukwenza into esebenzayo, enokwethenjelwa, ngaphansi kwezimo zomhlaba wangempela. Futhi lokho kusebenza kwenziwa isikhathi eside ngaphambi kokuba kwenziwe i-weld yokugcina.
