Xa abantu bethetha ukuphosa ukuchaneka, into yokuqala edla ngokufika engqondweni kukunyamezela kumzobo, mhlawumbi into efana ne-± 0.5mm. Leyo yinxalenye yayo, ngokuqinisekileyo, kodwa ukuba uchithe naliphi na ixesha lokwenyani kumgangatho wesiseko, uyazi ukuba yinto nje engaphezulu. Ukuchaneka okuyinyani kokusakhayo yile nto imdaka, iphelele-imalunga nokuzinza komda, ngokuqinisekileyo, kodwa malunga nokuthembeka komphezulu, isandi sangaphakathi, kunye nendlela eliziphatha ngayo inxalenye emva kokuba ikhutshiwe kwaye yapholiswa. Uninzi lwabathengi, ngakumbi abo batsha ekufumaneni ukuhanjiswa, balungisa kwelo nani elinye. Baza kufuna unyamezelo olungqingqwa ngendlela engenakwenzeka ngaphandle kokuqonda ukuba umqhubi weendleko ayisiyiyo nje isikhunta, kodwa yonke into ukusuka kwindlela yokuziphatha yokuncipha kwe-alloy ukuya kwindlela ocwangcisa ngayo inkqubo yokungena. Ndibone iiprojekthi zihamba ecaleni ngenxa yoko kuqhawulwa. Incoko yokwenyani kufuneka iqale ngomsebenzi: lenza ntoni eli candelo, ingaba ukuchaneka kubaluleke phi, kwaye sinokuvumela phi ukwahluka kwenkqubo ukuyigcina inoqoqosho? Kulapho amava angena khona.
UMthetho wokuHlanganisa ukuMngunda kwiqokobhe
Kwivenkile yethu, ukubunjwa kweqokobhe yinkqubo engundoqo, kwaye kulapho umlo omninzi ochanekileyo usilwa khona. Ubuhle bayo kukugqiba okugqwesileyo komphezulu kunye nokuchaneka okusemgangathweni onokuthi uphume ngqo kubumba. Kodwa ukuba nesidima akusoloko kwanele. Ukuchaneka apha ngumsebenzi othe ngqo wepateni. Ukuba ipatheni yakho enkulu ayifezekanga, ukubalwa kwamazinga okucutheka ukuya kutsho kwiqhezu lepesenti, uphinda-phinda impazamo. Sisebenzisa i-epoxy ephezulu okanye iipateni zetsimbi, kwaye ukugcinwa kwazo kubaluleke kakhulu. Itshiphu encinci okanye intsalela ye-arhente yokukhulula ikotshwa kwiqokobhe ngalinye olenzayo.
Kuphinde kubekho iqokobhe ngokwalo. Ubukhulu bayo kunye nokufana kwayo kukhulu. Indawo encinci ingakhokelela ekutshisweni okanye i-bulge, ibulale ukuchaneka komda wakho. Silawula oku ngokudipha kunye ne-stuccoing parameters-i-slurry viscosity, ubukhulu bengqolowa yesanti, ixesha lokumisa phakathi kweedyasi. Kuvakala kuyinkqubo, kodwa kwindawo engalawulwa yimozulu (engekhoyo iziseko ezininzi), imini efumileyo inokuwulahla umjikelo wakho wokomisa, okukhokelela kwiqokobhe elibuthathaka, elinozinzo olungaphantsi komlinganiselo. Ufunda ukufunda umoya, hayi nje incwadi yesikhokelo. Injongo liqokobhe elomeleleyo ngokwaneleyo ukuba likwazi ukuphatha intsimbi enyibilikisiweyo yoxinzelelo olungagungqiyo ngaphandle kokugqwetheka, kodwa hayi ngqindilili kangangokuba ibangela ukubanda okugqithisileyo okanye idale iindawo zayo zoxinzelelo. Kukuhlengahlengiswa rhoqo.
Ndikhumbula ibhetshi yemizimba yevalvu kwi-duplex stainless steel kwiminyaka embalwa edlulileyo. Iiprinta zafuna ukunyamezela okuqinileyo. Iigobolondo zazigqibelele, i-alloy yayiza kucaciswa, kodwa i-bores-cast-cast yayihlala ihleli kumda ophantsi. Ingxaki? Kutshanje sitshintshele kumxube omtsha wesanti ye-zircon kwiidyasi zokuqala. Yayinokuhanjiswa kwe-thermal eyahluke kancinane, etshintshe umphambili wokuqina ngokwaneleyo ukuchaphazela ukushwabana kwelo candelo libalulekileyo. Ulungiso lwalungengomatshini ngakumbi-yayikukuhlengahlengisa imilinganiselo yoshicilelo engundoqo yepateni ngezishumi ezimbalwa ukubuyisela ukuziphatha kweqokobhe elitsha. Kunjalo ukuphosa ukuchaneka: ukulawula uluhlu lwezinto eziguquguqukayo, hayi enye.
Ukwenziwa koTyalo-mali: Ukuleqa iNtsomi yoBume boMnatha
Ukwenziwa kotyalo-mali kwenza ukuba ileyibhile echanekileyo iphoswe kakhulu, ihlala ithengiswe njengenkqubo yobume bomnatha. Kwaye kunokuba njalo, kwiijometri ezithile. Kodwa i-net-shape incinci yengoma ye-siren. Inkqubo yokutofa kwe-wax yazisa izinto zayo eziguquguqukayo-uxinzelelo lwesitofu, ubushushu, kunye nexesha lokupholisa zonke zichaphazela ubungakanani bepateni ye-wax. Ukwahluka kwe-0.1% ekushwabaneni kwewax kuye kwandiswa ngokwakhiwa kweqokobhe leceramic kunye nokugalelwa kwentsimbi yokugqibela. Kuninzi lotyalo-mali olukwinqanaba lentengiso, usajonge isibonelelo somatshini, esincinci kakhulu.
Apho ikhazimla khona ngokuchaneka ineempawu zangaphakathi kunye neekhonto ezintsonkothileyo ezixabisa kakhulu kumatshini. Cinga ngee-impellers okanye iiblade ze-iturbine ezinamachaneli okupholisa angaphakathi. I ukuphosa ukuchaneka nantsi malunga nokubamba loo geometry ngokuthembekileyo. Umceli mngeni kukuthintela ukutshintsha kwe-ceramic engundoqo okanye ukugqwetheka ngexesha lokukhupha i-waxing kunye nokudubula. Sihlala siyiyile umthi wokudityaniswa kwewax kunye nesango lokungena ngokukodwa ukubambelela kunye nokuxhasa iicores eziethe-ethe. Yiphazili. Iphazili engaphumeleliyo ithetha ukuphosa apho ipaseji yangaphakathi ingekho embindini, inika indawo engenamsebenzi nangona umphandle ogqibeleleyo.
Sasebenza kwiprojekthi yecandelo lesixhobo sonyango, i-cobalt-chrome alloy part ene-lattice structure. Ukwenza oomatshini kwakungaphandle kombuzo. Imfuno echanekileyo yayingaphantsi malunga nomlinganiselo othile womgca kunye nokunye malunga nokuhambelana kweedamitha ze-lattice strut kunye ne-porosity yomhlaba. Siye sahamba ngeeresiphi ezininzi zewax kunye neqokobhe. Impumelelo yavela ekulungiseni ubushushu bangaphambi kobushushu bomngundo ngaphambi kokugalelwa. Kushushu kakhulu, kwaye isinyithi siya kutshabalalisa iinkcukacha ezintle ze-ceramic; kubanda kakhulu, kwaye isinyithi sasingenakuzalisa amacandelo amancinci ngokupheleleyo. Ukuchaneka kwachazwa ngokuphinda-phinda kumakhulu amalungu, hayi nje ukubetha inani kwenye.
INdawo nguMyalezo
Awukwazi ukuthetha ngokuchaneka ngaphandle kokuthetha ngentsimbi ngokwayo. Apha kulapho uninzi lwabaseki begeneric babetheka eludongeni. E-QSY, ukusebenza ngayo yonke into ukusuka kwintsimbi eqhelekileyo ukuya kwi-nickel-based alloys kuthetha ukuba kufuneka ubuyisele izinto ozilindeleyo kumsebenzi ngamnye. I-iron engwevu inolwelo olulungileyo kunye nokuncipha okuqikelelwayo, malunga ne-1%. Kuxolela ngokwenene. Kodwa tshintshela kwi-precipitation-hardening steel stainless okanye i-high-nickel alloy, kwaye umdlalo uphela uyatshintsha.
Ezi alloys ezikhethekileyo zineempawu ezahlukileyo ze-thermal contraction. Abanye bathanda ukukrazuka okushushu ukuba ukungunda kuqinile, okukunyanzela ukuba usebenzise imathiriyeli yokubumba engazinzanga kangako-urhwebo olukhawulezileyo. Ezinye, njengezinye iibronzi ze-aluminiyam, zinoluhlu olude lokuqiniswa, nto leyo ezenza ukuba zichaphazeleke kwi-micro-porosity, enokuthi ibonakale kuphela kwi-X-reyi kodwa inokuchaphazela ukusebenza kwenxalenye phantsi koxinzelelo. Uyilo lwakho lokungena kunye nokunyuka luba lubaluleke kakhulu ukuchaneka, kungekuphela nje ukunqanda imingxunya ecuthekileyo, kodwa ukuqinisekisa ukuqina komkhombandlela okunciphisa uxinzelelo lwangaphakathi kunye nokugqwetheka. Inxalenye ejikelezayo emva konyango lobushushu ayiyonxalenye echanekileyo, nokuba ilinganiswe ngokugqibeleleyo kwindawo eluhlaza.
Oku sikufunde kabuhlungu ngothotho lwezindlu zempompo ezinkulu kwi-nickel-chromium alloy. Amanqaku okuqala aphumelele iitshekhi zobukhulu. Kodwa emva kokulungiswa kobushushu besisombululo, zajika njengeebhanana. Umba yayiluxinzelelo olushiyekileyo olutshixelwe kwisamente ukusuka ekupholiseni okungalinganiyo. Kuye kwafuneka sibuyele umva kwaye siyila ngokutsha izinyusi kwaye songeze amaphiko okupholisa okucwangcisiweyo kumngundo ukukhuthaza ukuqina okufanayo. Ukuchaneka kuye kwafuneka kubunjineli kulawulo lwe-thermal yenkqubo, hayi nje umgodi wokungunda.
Apho i-CNC Machining ingena khona (ayisiyo intonga)
Uninzi lwabantu lucinga ngobuchwephesha be-CNC njengenyathelo lokucoca ukufezekisa ukuchaneka kokugqibela, kwaye ukuya kuthi ga kwinqanaba, yinyani leyo. Kodwa ukuba uyayisebenzisa njengesixhobo sokuziqhelanisa kakubi, imida yakho iyajika. Injongo kukubonelela ngokusasazwa okuchaneke ngokwaneleyo ukwenzela ukusetyenzwa kakuhle. Oko kuthetha ukuba ubukhulu bodonga olungaguquguqukiyo, isibonelelo esiqikelelwayo sesitokhwe, kunye neziphene ezincinci ezifihlakeleyo ezinokwaphula isixhobo.
Umatshini wethu wangaphakathi kwi-QSY wenza i-loop impendulo eqinile. Oomatshini basixelela ngokuchanekileyo apho isitokhwe sahluka khona, ziphi iindawo eziqinileyo, okanye ukuba ukuphosa kuphuma ngexesha lokubamba. Loo ngqondo ibuyela ngqo kwi-Foundry. Umzekelo, ukuba sihlala sibona i-0.3mm yesitokhwe eyongezelelweyo ebusweni obunye, sinokuhlengahlengisa ipateni okanye inkqubo yokubumba ukuyibuyisela. Le synergy yiyo esivumela ukuba sithembise ngokuthembekileyo ukuphosa ukuchaneka. Ayingomlingo; lunxibelelwano.
Ndikhumbula umsebenzi okwixabiso eliphezulu kwizibiyeli zeemoto. Unyamezelo lwe-as-cast kwimiphakamo yebholithi ethile ibingumda womxhasi womatshini womatshini ozenzekelayo womthengi. Babefuna ukungaguquguquki ngokugqithiseleyo. Ngokuhlalutya iinxalenye zoomatshini abangamakhulu ambalwa, sichonge unxulumano phakathi kobushushu bokugalela kunye nobude bokugqibela bomphathi emva komatshini. Iqondo lokushisa eliphezulu kancinane likhokelele ekucuthekeni okuncinci kwelo candelo likwanti, elinzima. Sayiqinisa ifestile yethu yokulawula isantya, kwaye ingxaki yaphela. Ukuchaneka kwaphunyezwa ngokulawula inkqubo eguquguqukayo ebesingakhange siyithathele ingqalelo ekuqaleni loo dimension.
I-Real-World Compromise kunye neXabiso lokuhambisa
Ngoko, emva kwayo yonke le nto, yintoni na ukuphosa ukuchaneka? Ngokwenyani, isoloko ibubugcisa obunokwenzeka ngaphakathi kwenyani yezoqoqosho. Kukwazi ukuba kuxelwa nini ukuskena kwe-CT yendawo ebalulekileyo ye-aerospace xa i-UT eqhelekileyo kunye ne-dimensional check yanele kwi-hydraulic manifold. Kukuqonda ukuba uburhabaxa bomphezulu obuyi-0.25mm (Ra) bunokufikeleleka njengokusaswa kotyalo-mali, kodwa inxalenye enkulu yeqokobhe lokungunda, ichaza i-1.6mm Ra kunye nokucwangciswa kokupasa komatshini okhawulezayo kubukrelekrele kwaye kunexabiso eliphantsi.
Ixabiso esilinikayo kwinkampani efana neQingdao Qiangsenyuan Technology ayiphelelanga nje ekwenzeni imilo. Kukukhokela umxhasi kolu rhwebo. Unokufumana indlela yethu kunye nezakhono ezichaziweyo apha https://www.tsingtaocnc.com.
