Xa usiva Co T400, into yokuqala abaninzi abafana abathengayo bacinga ukuba i-cobalt alloy, ukuchasana kakuhle kokugqoka, kwenziwa. Nantso inqanaba elithathwayo, kwaye ngokunyaniseka, kulapho iivenkile ezininzi zikhubeka khona. Asiyonto nje ikhowudi yezinto; yindlela yokuziphatha. Ngaphezulu kwamashumi amathathu eminyaka ekujuleni nasekusebenzeni, ndiwubonile umsantsa phakathi kwesithembiso sedatha yedatha kunye nenyaniso yomgangatho wevenkile ngezi ngxubevange. Wonke umntu uthetha ngamandla akhe aphezulu obushushu kunye nokumelana nokugqwala, kodwa ibali lokwenyani likwi-chip formation, izixhobo zokugqoka iipatheni, kunye nendlela ephendula ngayo kwiindlela zokupholisa ezahlukeneyo. Yimpahla efuna intlonipho, hayi nje iodolo yokuthenga.
Inyani yoMgangatho weFoundry kunye neCobalt Alloys
Umsebenzi wethu eQingdao Qiangsenyuan Technology Co., Ltd. (QSY) uhlala uqala ixesha elide ngaphambi kokuba umatshini we-CNC ujikeleze. Ngemathiriyeli efana Co T400, inkqubo yokuphosa ibeka iqonga kuyo yonke into elandelayo. Sisebenza ngokukhethekileyo kukungunda kweqokobhe kunye nokuphosa utyalo-mali ngesizathu-uzinzo lwe-dimensional kunye nokuthembeka komphezulu. Ukugalela i-cobalt-based alloys akufani nokugalela i-standard stainless. Kukho i-thermal dynamics eyahlukileyo, ipateni yokuqina eyahlukileyo. Ukuba ufumana isango lokungena okanye ukunyuka okungalunganga kweli nqanaba, wenza nje isiqwenga esibiza kakhulu, esinzima kakhulu sesilahlwa kamva. Ndibone iindawo ziphuma kubumba zijongeka zigqibelele, kuphela kumatshini wokutyhila i-subsurface porosity ebulala isixhobo ngemizuzwana. Intsebenziswano phakathi kwe-Foundry yethu kunye nevenkile yoomatshini ayinakuxoxisana kweli bakala.
Enye intloko ebuhlungu kunye ne-400-series cobalt alloys kukuhlukana kwee-carbides. Kutyalo-mali, ungafumana ulwakhiwo oluhle lweenkozo eziziinkozo, kodwa ukuba izinga lokupholisa alilawulwa ngobuchule, ezo ziqwengana zekhabhidi zilukhuni. Emva koko, xa usiya kumatshini, umsiki wakho akadibani nezinto ezifanayo. Ibetha ezi pokotho ze-microscopic, ezi-abrasive ezibangela ukungaqikeleleki, ukunxiba kweflank okukhawulezileyo. Ayibonakali kwingxelo yovavanyo lobulukhuni, kodwa iyakhala kuwe kwisixhobo sokuhlola. Kulapho iminyaka engama-30 yokuqatshelwa kwepateni ingena khona-ukwazi ukufunda ulwakhiwo lwesamente phambi kokuba kuqale umsebenzi wokuqala.
Oku sikufunde kabuhlungu kumsebenzi wecandelo le-aerospace. Imizobo ibifuna Co T400, kwaye safumana i-alloy, sayiphosa kwi-spec, kwaye saqhubeka nokwenza machining. Amacandelo ambalwa okuqala ayelungile, kodwa emva koko ubomi besixhobo baba nokungahambelani. Sisole isixhobo, iiparamitha, yonke into. Emva kokukrazula iinwele zethu, sabuyela kwiindawo ezingenanto kunye nohlalutyo lwe-metallurgical. Umba ibiyi-carbide banding echuliweyo, isiphumo sokungahambelani okuncinci kubushushu bethu bokugalela obuvunyelwe ngummiselo. Ulungiso lwalungekho kwinkqubo yomatshini; kwakusekuqiniseni ulawulo lwethu lwenkqubo yesiseko ngaphaya komgangatho. Ngoku, kumacandelo abalulekileyo, siphatha i-microstructure njenge-cast-cast njengendawo yokuqala kunye neyona nto ibalulekileyo yokuhlola.
I-CNC Machining: Umdaniso weeParamitha kunye nomonde
Kulungile, ngoko unesandi esisasazwayo. Ngoku umdaniso wokwenyani uyaqala. Umatshini Co T400 kulapho iifidi zethiyori kunye nezantya zidibana nenyani yokusila. Awukwazi ukuphosa nje i-carbide esemgangathweni kwaye unethemba lokuhle. Sibe neyona mpumelelo ingaguqukiyo ngamabakala azinikeleyo e-submicron carbide, ngamanye amaxesha sifudukela kwi-ceramic okanye kwi-CBN yokugqiba ukupasa kwiimeko ezinzima. Kodwa isihlomelo sisiqingatha kuphela sebali. Ukuqina yinto yonke. Nayiphi na incoko, nayiphi na i-harmonic vibration, kunye nezinto eziphathekayo zibonakala zisebenza nzima, zidala ukungaphumeleli kwe-cascading.
Eyona mpazamo inkulu ndiyibonayo ngabadwelisi benkqubo bayiphatha njenge-Inconel ye-super-alloy. Amandla okusika ahlukile. Nge Co T400, kufuneka ugcine ukusika okuhambelanayo, okulungileyo. Umjikelo wokukrola ekwembeni, umzekelo, kunokuba yingozi ukuba uyeka isixhobo sihlikihle ezantsi komngxuma. Idala ubushushu bendawo kunye nomsebenzi wokuqina onokuthi ubambe i-drill elandelayo. Siye safudukela kusomba ukutya okucokisekileyo ngokupholisa okukhethekileyo, kwaye amazinga ophuka ehle kakhulu. Ngama-nuances amancinci-uhlobo olufunda kuphela ekubambeni ii-drill ezimbalwa zee-$ 300-ezenza umahluko phakathi kwengeniso kunye nelahleko emsebenzini.
Isipholisi asenzelwa ukupholisa nje apha; yiarhente yokuthambisa kunye neqabane lokukhupha itshiphu. Siqhuba iinkqubo ezinoxinzelelo oluphezulu, ezinomthamo ophezulu. Itshiphu evela Co T400 inokuba ngqongqo kwaye ibenzima. Ukuba ayicacisi indawo yokusika ngokukhawuleza, iphinda inqumle, yonakalise umphezulu kunye nokulayisha isixhobo. Sakhe saba nomsebenzi onzulu wokugaya ipokotho apho yonke into yayigqibelele kukulinganisa. Emgangathweni, sagqitywa kakubi kwaye sinxibe izixhobo ezikhawulezayo. Ingxaki? Uxinzelelo olupholileyo lwalungenamandla ngokwaneleyo okukhupha iitshiphusi kwikona enzulu. Utshintsho lwehardware olulula kumiselo lwe-nozzle ezimbini oluqondiswe ngqo kwindawo esikiweyo luyisombulule. Isifundo: ungaze ucinge ukuba imeko-bume yomatshini yeyesibini kwindlela yesixhobo.
I-Application-Driven Compromises kunye noKhetho lweMathiriyeli
Kutheni nokuba usebenzise Co T400? Kuyabiza kwaye kubuhlungu kumatshini. Impendulo ihlala ikwimfuno zesicelo. Sihlala sinikezela ngezixhobo zeevalvu zenkonzo ebukhali, iinxalenye zokunxiba impompo, kunye nezinto zokufakwa kwi-aerospace. Kwezi meko, indibaniselwano yokumelana nokhukuliseko-i-corrosion kunye namandla agcinwe kumaqondo obushushu aphezulu kwenza kube lolona khetho. Kodwa i-Co T400 ayisiyiyo i-monolith. Iipropati ezichanekileyo zinokutshintsha ngokusekelwe kunyango lobushushu emva kokuphosa. Ngamanye amaxesha umxhasi ucela ubunzima obukhulu, engaqapheli ukurhweba kwi-machinability kunye nefuthe lokuqina.
Sasinomthengi onyanzelisa ubulukhuni be-Rockwell C phezulu kakhulu kuluhlu lwepleyiti yokunxiba. Siye sayenza ngoomatshini, kodwa isivuno sasibi ngenxa yokuqhekeka kancinci ngexesha lokugqiba. Sicebise ukuthomalalisa: ubulukhuni besambuku esisezantsi kancinane, kodwa ngonyango oluthile lobushushu ukwenza umaleko womphezulu oqinileyo, ongagugiyo ngelixa ugcina undoqo oqinileyo. Iqhube ngcono entsimini kwaye yayinoqoqosho oluthe chatha ukuvelisa. Le yinxalenye yomsebenzi wethu kwi-QSY-hayi ukwenza nje ushicilelo, kodwa ukucebisa ngeyona nguqulelo inokwenziwa kunye nesebenzayo yoyilo. Ukulandela ngobumfama i-spec yemathiriyeli ngaphandle kokuqonda ukuba kutheni iresiphi yokuphoxeka.
Oku kundizisa kwindawo ehambelanayo: umtsalane wezinto ezilinganayo. Kwizigaba eziphantsi kweendleko, iinjineli zinokujonga kwi-alloys esekwe kwi-nickel okanye nakwiintsimbi ezingenasici. Kweminye imisebenzi, inokusebenza. Kodwa ngenxa yokwenyani ukuxhathisa kwenyongo kwiindawo zokukhwelana, okanye kwindawo ene-sulfidation okanye i-abrasion eshushu yothuthu, i-matrix esekwe kwi-cobalt. Co T400 yahlukile. Siqhube iimvavanyo zentsimi zokuthelekisa kubathengi, kwaye umahluko kubomi benkonzo unokuba ziiodolo zobukhulu. Ayilonyuso; sisisombululo esikhethekileyo seseti yeengxaki.
Iintsilelo, iziFundo, kunye neNkqubo yoManyano
Awunakulunga apha ngaphandle kwamanxeba athile. Enye yezona ntsilelo zethu ezifundisayo yayiyibhetshi yezinto ezintsonkothileyo, ezinodonga olucekethekileyo. Ukulingisa bekulucelomngeni kodwa kuphumelele. Ngexesha lomatshini we-CNC kwii-mills zethu ze-5-axis, siye safumana ukuphazamiseka okuyingozi ekugqityweni kokugqiba. Siye sakhulula lonke uxinzelelo lwangaphakathi ngonyango lwe-thermal, okanye ngoko sasicinga. Umba yayiluxinzelelo olushiyekileyo olusuka kwinkqubo yomatshini ngokwayo. Iipasile ezirhabaxa, ezenziwe ngeeparamitha ezinobundlongondlongo zokonga ixesha, ziye zabangela uxinzelelo olwaneleyo lwasekhaya kangangokuba xa sithatha isisimbo sokugqibela sokukhanya ukuze sifikelele ukunyamezelana, kwavela inxalenye.
Ukulungiswa kwakuchasene ne-intuitive: kwafuneka sehlise isantya. Siphuhlise isicwangciso esinamanqanaba amaninzi kunye namanyathelo okunciphisa uxinzelelo (ukunciphisa uxinzelelo lwe-vibratory, kule meko) phakathi kwemisebenzi. Yongeza ixesha kumjikelo, kodwa yenza ukuba inkqubo iqikeleleke kwaye yaphelisa inkunkuma. La mava ayitshintshile indlela yethu yokwenza izinto ezinexabiso eliphezulu, ezintsonkothileyo zokusaswa kwizinto ezinzima. Ngoku yinxalenye yenkqubo yethu esemgangathweni yokuhamba kwezinto ezibalulekileyo Co T400 amacandelo. Ungafumana enye yale filosofi iphumelele nzima enzinziselwe kwindlela esiyibhala ngayo abathengi kwisiza sethu https://www.tsingtaocnc.com.
Olu hlobo lokufunda kungenxa yokuba umsebenzi odityanisiweyo ngokuthe nkqo njengeQSY unomphetho. Ingxelo yengxelo imfutshane. Xa umatshini unengxaki, iqela le-Foundry lilungile apho ukuze lixoxe ngesakhiwo sokuphosa. Xa i-Foundry izama ubuchule obutsha, oomatshini baziva iziphumo ngokukhawuleza. Kwimathiriyeli ene-nuanced njenge Co T400, olu manyano luxabisekile. Isusa incoko kwityala (ukuphosa kwakho kubi) ukuya ekusonjululweni kwengxaki ngokudibeneyo (siyihlengahlengisa njani inkqubo yale geometry?).
Ukukhangela Phambili: Ayiyiyo Nje Imveliso
Ukuqhubela phambili, incoko ejikeleze izixhobo ezifana Co T400 iyatshintsha. Ayikokuthenga nje iikhilogram zealloyi. Imalunga nokuthenga isisombululo esenziweyo esibandakanya ulwazi lwenkqubo ukuyenza. Imveliso eyongezelelweyo iyankqonkqoza emnyango kwezinye zezi zicelo, kodwa ngenxa yentembeko ephezulu, iikhomponenti ezinomthamo ophezulu, ukuphosa okulandelwa ngokuchaneka kweCNC machining kusabonelela ngokudityaniswa okungenakulinganiswa kokulawulwa kwepropathi kunye neendleko.
Umda olandelayo kuthi kukudityaniswa okuqina ngakumbi kokulinganisa. Sisebenzisa uhlalutyo lwento elinganiselweyo (i-FEA) ukwenza imodeli yenkqubo yokuphosa ukuqikelela usasazo lwe-carbide luyingxaki, kwaye emva koko sondla loo datha kwisoftware yeCAM ukulungelelanisa iindlela zesixhobo ngokusekwe kuqikelelo lwe-heterogeneity yezinto. Yimihla yokuqala, kodwa injongo kukusuka kwisisombululo esisebenzayo sokusombulula ingxaki ukuya kulawulo lwenkqubo eqikelelweyo. Isixhobo sisisigxina; ukukwazi kwethu ukuqonda kunye nokukhohlisa inkqubo ejikeleze kuyo kuguquguqukayo esihlala sisebenza kuso.
Ke, xa uvavanya Co T400 kwiprojekthi, jonga ngaphaya kwephepha ledatha. Cinga ngesandi sokuphosa, iqhinga lomatshini, unxibelelwano lonyango lobushushu, kunye nexabiso lilonke lobunini, hayi nje ixabiso lempahla ngekhilogram. Umgangatho ulele kwimithungo phakathi kwamanyathelo okuvelisa, kwaye kulapho amashumi eminyaka amava agxilileyo, njengale siyakhe eQingdao Qiangsenyuan, ekugqibeleni ahlawule. Ngumahluko phakathi kwenxalenye edibana ne-spec kunye necandelo elisindayo endle.
