Uyazi, xa abantu abaninzi besiva 'umzimba wevalvu,' bafanekisela ibhloko eyenziwe yafana nejenerikhi, enzima enemingxuma egrunjiweyo kuyo. Yimpazamo enkulu yokuqala leyo. Kumgca wethu womsebenzi kwi Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), siye sabona ukuba ingqondo ikhokelela kuzo zonke iintlobo zemiba ephantsi-ukunxiba kwangaphambili, ukuvuza, ukusilela kwenkqubo yentlekele. Inyaniso kukuba, a umzimba wevalvu yisiseko se-chassis; ingqibelelo yayo ilawula yonke into. Ayikokuqulatha nje uxinzelelo; imalunga neendlela zokuhamba ezichanekileyo, uzinzo lwe-thermal phantsi kwee-gradients eziphambeneyo, kunye nokuxhathisa ukubola kwimidiya ongayi kukholelwa. Ukuyenza impazamo kuyabiza, kwaye ndineendawo ezilahliweyo zokungqina oko.
I-Conundrum yokuphosa: Apho Iqala khona (okanye iyeke)
Wonke umntu ufuna ukutsibela ngqo kwi-CNC yonyamezelo lomatshini. Ndiyayifumana, nantso inxalenye enomtsalane. Kodwa ukuba ukulahla kwakho yinkunkuma, akukho bungakanani bomatshini obumnandi obuya kuwugcina. Kulapho amashumi amathathu eminyaka ethu kubumba lweqokobhe kunye nokuphosa utyalo-mali luluma ngokwenene. Kuba umzimba wevalvu elungiselelwe umphunga ophezulu woxinzelelo okanye iikhemikhali ezonakalisayo, isandi sangaphakathi asinakuxoxisana. I-microscopic shrinkage cavity awukwazi nokuyibona kwi-X-reyi? Leyo yinkangeleko yokudinwa kwixesha elizayo elindele ukwenzeka. Sifunde oku ngendlela enzima kwangethuba ngebhetshi yomthengi wepetrochemical. Amalungu aphumelele uvavanyo lokuqala loxinzelelo, kodwa aluphumelelanga kwi-situ emva kwemijikelo embalwa ye-thermal. Oyena nobangela? Ukupholisa okungahambelaniyo kwicandelo elishinyeneyo lenkqubo yotyalo-mali. Yayingesosiphene soyilo; yayiyinkqubo yokulawula ihiccup.
Yiyo loo nto ukhetho lwemathiriyeli ingeyobhokisi yokukhangela. Insimbi engenasici yindawo yokuqala, ayisosisombululo. Ngaba yi-304 ye-corrosion jikelele, okanye i-316 ye-chlorides? Ngobushushu obugqithisileyo kunye ne-sulfidation, ujonge kwi-Inconel 625 okanye i-Hastelloy C-276-ezo ngxubevange ezisekwe kwi-nickel sisebenza ngokukhethekileyo kuzo. Ubuchule bokuphosa butshintsha ngokupheleleyo. Ngezi superalloys, iqondo lobushushu lokugalela, ukutshisa kwangaphambili ngundo, kunye nesantya sokupholisa kufuneka kube kumdaniso ogqibeleleyo. Ukutenxa kancinci kwaye ufumana ulwahlulo, izigaba ezinqabileyo. I umzimba wevalvu inokubonakala igqibelele, kodwa iya kuqhekeka ngexesha lomatshini okanye, ngakumbi, enkonzweni. Sichitha ixesha elingakumbi sifanelekela iiparameters zethu zenkqubo kwi-alloy entsha nganye kunokuba senzayo kwimveliso yangempela eqhutywe kwinqaku lokuqala.
Ndikhumbula iprojekthi yosetyenziso lwe-geothermal. I-spec ibize i-duplex yentsimbi engatyiwayo umzimba wevalvu. Lucelomngeni? Ukugcina kufutshane ne-50/50 ibhalansi yesigaba se-austenite-ferrite ngokuphosa kunye nonyango olulandelayo lobushushu ukuze ufumane loo mxube wamandla kunye noxinzelelo lwekloridi yokuchasana nokuqhekeka kokuqhekeka. Ukukhawuleza ngokukhawuleza, kwaye ujika umlinganiselo. Kwasithatha iibhetshi zokulinga ezine, ukusika iisampuli zohlalutyo lwe-metallographic ngexesha ngalinye, ukutshixa kwinkqubo. Iinjineli zabathengi babecinga ukuba sicokise kakhulu. De iivalvu zabo bakhuphisana nabo, ezithathwe kwisiseko esinexabiso eliphantsi, zaqala ukusilela kwisithuba sonyaka. Ezethu zisesemhlabeni.
UMatshini: Apho ijometri idibana neNyiniso
Kulapho isicwangciso siphila khona, kwaye apho uninzi lweentloko zibonakala. Ufumana icasting ukusuka kumgangatho wesiseko. Kubonakala kulungile. Emva koko uyibeke kwi-CMM (Umatshini wokulinganisa wokuLungelelanisa) emva kokusebenza kokuqala, kwaye ubona utshintsho oluphambili. Mhlawumbi sisiqingatha semilimitha kuphela, kodwa xa unothungelwano oluntsonkothileyo lwebhore engenelayo yevalve trim, eso-millimeter yintlekele. Zonke iidatum zakho zicimile. Ngaba uyazama ukuyisindisa ngokuhlengahlengisa inkqubo yakho yomatshini, enokuthi ibeke esichengeni ubukhulu bodonga? Okanye ngaba ulahla i-$ 5,000 yokuphosa? Ezi ziifowuni zemihla ngemihla.
CNC Machining a umzimba wevalvu ayikokubetha nje +/- 0.01mm. Imalunga nokulandelelana. Ngaba usebenzisa ubuso beflange kuqala ukuseka i-datum yokuqala, okanye ngaba urhabaxa imingxunya yangaphakathi ukukhulula uxinzelelo? Kwimizimba emikhulu, entsokothileyo efana naleyo yeevalvu eziphambili zokwahlula umphunga, sihlala sisenza i-anneal yokunciphisa uxinzelelo emva komatshini orhabaxa. Kuya kufuneka ushiye isitokhwe esaneleyo ukwenzela ukuba emva kokuba inxalenye ihamba kancinci esithandweni somlilo, usenako ukuyicoca kwiipasile zokugqiba. Ukuba awuyicwangcisi loo ntshukumo, uya kufumana iipokotho zakho zokuhlala ezigqityiweyo azisagxininisi.
Tooling iqhinga omnye umbulali cwaka. Ukugrumba ubunzulu, imingxunya enqamlezileyo yesixhobo okanye izibuko ezophayo kwi-austenitic stainless steel casting? Loo nto ithanda ukusebenza nzima. Sebenzisa isondlo esingalunganga/isantya, okanye i-drill ethe yabuthuntu kancinci, kwaye uya kubengezela eludongeni lomngxuma. Isixhobo esilandelayo, njenge-reamer, siya kuvele sityibilike kwindawo eqinile, sonakalise ububanzi kunye nokugqiba. Siye sabeka emgangathweni kumabanga athile e-carbide kunye nezixhobo eziqinileyo ezondliwa ngokupholisa kule misebenzi emva kokukrazula iindawo ezininzi eziphantse zagqitywa. Yile ngcaciso emfutshane, iinkcukacha ezingathandekiyo ezahlula inxalenye esebenza kuleyo igqwesileyo. Ungafumana enye yeendlela zethu kule mingeni inzima yomatshini kwindawo yethu https://www.tsingtaocnc.com, nangona eyona nuance yokwenyani isoloko ijongene nomsebenzi othile.
Umngxuma woMvundla oKhethekileyo
Abathengi beza kuthi QSY ngokufuthi ngenxa yokuba baye bafikelela kumda wezinto eziphathekayo. Iintsimbi eziqhelekileyo aziyinqumli. Kulapho ifumana umdla, kwaye ngokungafihlisiyo, apho ufumana igama lakho. I-alloys esekwe kwi-Cobalt njenge-Stellite 6, ehlala isetyenziswa njengezihlalo ezinobuso obunzima ngaphakathi umzimba wevalvu, bonisa indida. Zinxibe ngendlela emangalisayo kwaye ziyakwazi ukumelana nomhlwa, kodwa ziyingozi kakhulu kumatshini. Ziintsini, zilahla izixhobo zokusika, kwaye zivelisa ubushushu obukhulu. Awukwazi ukuphosa nje umgangatho wokufaka kuyo.
Kwafuneka siphuhlise zonke iiprothokholi zesiko: isantya esicothayo kakhulu, ukondla okuphezulu, izixhobo ezikhethekileyo zejometri ezinerakhi ezintle kakhulu, kunye nokupholisa okukhulu koxinzelelo lokwaphula itshiphu kunye nokuthwala ubushushu kude. Ngamanye amaxesha, kwiintlobo ezinzima kakhulu, siyayishiya i-machining yendabuko ngokupheleleyo yokugaya okanye i-EDM (i-Electrical Discharge Machining) kwiimpawu ezithile. Ingongoma kukuba, izinto ze umzimba wevalvu ngokwayo, okanye ingxubevange oyifakela kuyo, iyalela yonke imephu yendlela yokwenza. Akukho nkqubo ye-CNC yobukhulu obunye. Yinkqubo eqhubekayo yokuziqhelanisa.
Kwaye ayibomatshini kuphela. Ukuwelda i-nozzle okanye i-patch yokulungisa kwi-alloy-based alloy umzimba wevalvu ifuna utyando oluchanekileyo. Ukushisa kwangaphambili, ukulawula ukushisa kwe-interpass, iingcingo ezithile zokuzalisa, kunye ne-PWHT engqongqo (i-Post-Weld Heat Treatment) ukubuyisela i-microstructure. Fumana naliphi na inyathelo elingalunganga, kwaye udala indawo yobuthathaka echaphazeleka ngakumbi kukusilela kunesiphene sokuqala. Sigcina iseli ezinikeleyo kolu hlobo lolungiso lweweld oluchanekileyo kuba lubaluleke kakhulu, isakhono esikhethekileyo. Ayingomsebenzi wasefektri; ikufutshane kwi-metallurgy art.
Uvavanyo kunye noMoya kumatshini
Uhlolo lokugqibela kulapho ukuzithemba kwakho kuvavanywa khona, hayi nje inxalenye. Uvavanyo lwe-Hydro ukuya kwi-1.5x yoyilo loxinzelelo lusemgangathweni, kunjalo. Kodwa lo ngumfanekiso wokupasa/usilele. Ayikuxeleli malunga nokunyuka kwexesha elide kwinkonzo yobushushu obuphezulu, okanye ubomi bokudinwa. Kwizicelo ezibalulekileyo, sityhala ngakumbi. Uvavanyo lokungena kwedayi (PT) kuzo zonke iindawo ezinomatshini ukufumana iintanda. Uvavanyo lweMagnetic particle (MT) kwizinto ze-ferritic. Kodwa umgangatho wegolide, ngakumbi utyalo-mali olutyebileyo, luvavanyo lweradiyographic (RT).
Ukhangele ezo ziphene zangaphakathi-i-shrinkage, i-porosity, inclusions. Iikhrayitheriya zokwamkelwa ngokwemigangatho ye-ASTM E zikhohlakele, kwaye kufuneka zibe njalo. Ndivume iifilimu ze-RT apho ukubunjwa kwakuneqela elincinci, elizimeleyo le-porosity kakuhle kude kuwo nawuphi na umda woxinzelelo okanye uxinzelelo. Ngokobuchwephesha, inokudlula i-spec ekhululekile. Kodwa ukuba ligama lam kwisatifikethi, kwaye ndiyayicingela loo nto umzimba wevalvu kumthi weKrisimesi ongaphantsi kolwandle okanye umgca wokupholisa wenyukliya, ndiya kuhlala ndiwugatya. Lubizo lomgwebo. Iindleko zokwenziwa kwakhona akukho nto xa kuthelekiswa neendleko zokungaphumeleli kwentsimi. Le ethos egcinayo ibhakiwe kwimisebenzi yethu e-QSY, ezalwe ukusuka kuloo 30 + iminyaka yokubona oko kunokungahambi kakuhle.
Emva koko kukho i-dimensionals. Ingxelo yeCMM ngamanani nje. Kufuneka uyifunde. Ukuba zonke iidiameters ezibhokile zikwi-spec kodwa zibonisa i-taper encinci, kuthetha ukuthini oko? Mhlawumbi isixhobo siye saphambuka. Mhlawumbi kukho uxinzelelo olushiyekileyo. Inokwamkeleka, kodwa ibonisa ukungazinzi kwenkqubo enokwenzeka kwicandelo elilandelayo. Umgangatho awupheleli nje ekugqithiseni; imalunga nokuqonda umda wokupasa kunye nentsingiselo. Siphatha ingxelo yokuhlola inqaku lokuqala njengoxwebhu lwenkundla.
Buyela kuMfanekiso Omkhulu
Ke, emva kwayo yonke le nto-iingxoxo ze-alloy, iimvavanyo zokuphosa, iintloko ezibuhlungu, ukuxinana kwe-angst-yintoni onayo? Unayo i umzimba wevalvu. Nje icandelo. Kodwa licandelo elibandakanya uthotho lwezigqibo, ubuchule, kwaye, ewe, i-paranoia encinci. Asiyonto yorhwebo. Xa uvela kwivenkile efana neyethu, awuthengi nje imilo eyenziwe ngoomatshini. Uthenga amashumi eminyaka elumkiso esimiliselwe esenze ukuba siqhube eso sitofu esongezelelweyo se-RT, ukuzimisela ukukrazula kunye nokuqalisa kwakhona, kunye nolwazi oluqokelelweyo malunga nendlela iitshiphusi zealloy ezisekwe kwi-cobalt kufuneka zijongeke ngayo xa ziphuma kwisixhobo ngokuchanekileyo.
Eli shishini lizele ziivenkile ezinokwenza imilo ekhangeleka ngathi umzimba wevalvu. Iqhinga lenza lowo unyamalalayo kwinkqubo iminyaka engama-30 kwaye usebenza nje, ulibele. Nantso injongo. Iqala ngokuhlonipha ukuntsokotha okufihlwe kwelo gama lilula, umzimba wevalvu, kwaye iphele ngenxalenye ekwinqanawa okanye kwisityalo ekungekho mntu ukhe acinge ngayo kabini. Yeyona metric yempumelelo yokwenyani, ngaphaya kwesatifikethi sokuhlolwa.
