Xa iinjineli zicacisa ukuphoswa kwentsimbi engwevu, aziyi kuodola nje iinxalenye-zibophelela kwisiseko sozinzo lwe-dimensional, i-vibration damping, kunye nokumelana nokunxiba kwexesha elide phantsi komthwalo wehlabathi lokwenyani. A umzi-mveliso wentsimbi engwevu ophumeza ezo zithembiso akaxhomekeke kumabango abanzi. Izibonakalisa kwimicrostructure yayo yonke ithululo, ukuphinda-phinda komjikelo ngamnye womatshini, kunye nokulandeleka ngasemva kwebhetshi nganye ephethwe bubushushu.
Ukuchaneka kuQala ngokuQinisekisa okuLawulwayo-Akukona nje ukuzaliswa kweMold
Siye sabona iiprojekthi ezininzi kakhulu zivaliwe kuvavanyo lokuqala olusebenzayo-kungekhona ngenxa yeziphene zoyilo, kodwa ngenxa yokuba ukuhanjiswa kwe-graphite flake akuhambelani ne-ASTM A48 Class 30B efunekayo yamandla okanye iprofayili yobunzima. Intsimbi engwevu ayiyontsimbi "elula". Ukusebenza kwayo kuxhomekeke kulawulo oluluqilima kwikhabhoni elingana (CE), izinga lokupholisa, ixesha lokugonywa, kunye nokuqina kokungunda. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke into eyenziwa yisanti iqala ngokuqinisekiswa kwe-spectrographic ye-ladle chemistry-kungekhona nje ukubunjwa, kodwa amandla e-oksijini kunye namanqanaba e-titanium ashiyekileyo. Yiloo ndlela esihlala sibambe ngayo ± 0.15 mm kwiibhore ezibalulekileyo kwizindlu zepiston pump cylinder, nakubunzima bodonga ukusuka kwi-12 mm ukuya kwi-65 mm.
Abathengi bahlala bebuza: "Ngaba unokuphosa imizimba yevalvu yoxinzelelo olucekeceke ngaphandle kokushwabana kwe-porosity?" Ewe-kodwa kuphela xa uyilo lokungena luqinisekiswa nge-MAGMAsoft ukulinganisa ukuqinisa *ngaphambi* kokuvunywa kwepateni, kwaye xa ushicilelo olungundoqo lwenziwa ukuxhathisa intshukumo ngexesha lokushukuma. Asikuphathi ukuphosa njengebhokisi emnyama. Senza imephu yeemitha ezishushu ngexesha lokwenyani sisebenzisa ii-thermocouples ezifakwe ngaphakathi ngexesha lokuqhuba isiqinisekiso. Le datha izondla ngokuthe ngqo kulungiselelo lwethu lwe-CNC-ngoko ke ukwenza oomatshini kuhlawulela ukushwabana okunokuxelwa kwangaphambili, hayi uqikelelo.
Ukomelela Kufuna Udityaniso oluthe nkqo-Hayi nje Ukuphosa okanye ukuSebenza Wedwa
Abanye ababoneleli banikezela ngokukhutshwa koomatshini bomntu wesithathu. Oko kudala izikhewu: imfezeko yomphezulu iyathotywa phakathi kodubulo lokudutyulwa nokujika kokugqibela; ukuphambuka konyango lobushushu kungakhange kulinganiswe de kuhlolwe okokugqibela; I-GD&T callouts efana nonyamezelo lwendawo Ø0.05 mm xa kuthelekiswa nedatum ephosiweyo ayinakukwazi ukuyibamba. Kwiziko lethu elithobela i-ISO eQingdao, iintsimbi ezingwevu zihamba ngaphandle komthungo ukusuka kwi-fettling ukuya kwi-multi-axis CNC-akukho kudluliselwa kwangaphandle, akukho kulungiswa kwakhona, akukho kulahleka kokuqhubeka kwedatum.
Olu hlanganiso luzisa iziphumo ezinokulinganiswa:
- Umphezulu ogqityiweyo kwizitulo zevalve yehydraulic ezibanjelwe kwi-Ra 0.8 µm-ngaphandle kokuqengqeleka okwesibini-kuba umatshini kulandela kwiiyure ezingama-24 zokuthomalalisa uxinzelelo.
- Ukungaguquguquki kweMicrohardness kuzo zonke iindonga (210-230 HBW) iqinisekiswe luvavanyo lwe-Rockwell B *emva konyango lokugqibela lobushushu, hayi ngaphambili.
- Ukulandeleka ngokupheleleyo: Inxalenye nganye iphethe i-ID ye-laser-etched lot edibanisa umva wohlalutyo olunyibilikayo, umhla wokuphosa, ijika lonyango lobushushu, kunye nengxelo yeCMM.
Kungenxa yoko le nto iiroli ze-winch ye-winch yemoto yeziko le-shaft-eziphantsi kokugoba ibhayisekile kunye noqhagamshelwano oluluqilima-zihlala zidlula iiyure ezili-12,000 zobomi basentsimini kwi-OEM yaseYurophu. Ukuqina awongezwa kamva. Yakhelwe kwindlela yokusebenza.
Ukuthembela kuzuzwa ngokuNgafihli—Hayi izatifikethi eDongeni
"Isiqinisekiso se-ISO" sithetha kancinci ukuba izatifikethi zezinto ezingenayo azikhange zihlolwe ngokuchasene neengxelo zovavanyo lokusila-okanye ukuba uhlolo lwe-dimensional lwenzeka kuphela kwinqanaba lokugqibela. Siyaqinisekisa ukuthotyelwa kwemathiriyeli ekrwada *phambi* kokunyibilika: uhlalutyo olubonakalayo lwentsimbi yehagu, umlinganiselo wentlawulo yenkunkuma, kunye nezongezo zeferroalloy zilogiwe kwaye ziyagcinwa. Yonke intsimbi engwevu ijongwa kwindawo ezintathu ezinyanzelekileyo:
- Ukuqinisekiswa kwezinto ezingenayo (i-spectral + isampulu ye-tensile ngobushushu)
- Kwinkqubo yokuskena kweCMM yeedatum ezibalulekileyo emva komatshini orhabaxa
- Umlinganiselo wokugqibela wokutywina weendawo zokutywina usebenzisa iinkqubo zombono we-5-micron
Akukho ngaphandle-nakwiprototypes. Omnye umenzi wempompo waseMntla Melika ufumanise oku ngexesha lomyalelo wabo wesibini: umzobo wabo ohlaziyiweyo uquka umcaba ongqongqo kwiflange enyukayo. Iqela lethu liyiphawule ngexesha lophononongo lobunjineli-hayi ngokukhatywa, kodwa ngesiphakamiso sokwenziwa kokwenziwa: ukutshintshwa kwedatha yokuphosa ukunciphisa ukuphambuka okubangelwa kukulungisa. Bakuvuma oko. Izinga lokwamkelwa kwenqaku lokuqala litsibe ukusuka kwi-68% ukuya kwi-100%.
Kutheni iiNjineli zehlabathi zibuyela kule Factory ye-Iron Castings eGrey
Akukho malunga nexabiso eliphantsi. Kumalunga nokuphelisa umngcipheko ofihlakeleyo-uhlobo oluvela ngexesha lovavanyo lwe-FAT okanye, ngakumbi, kwintsimi. Xa ivalve yakho yoxinzelelo kufuneka itywine kwibar ye-350 iminyaka engama-20, okanye isiseko sakho sempompo sichasa i-resonant frequency ukuya kuthi ga kwi-1,200 Hz, ukucinga kubiza ngaphezulu kokuchaneka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza apho i-metallurgy idibana nee-mechanics: iinkqubo zokuphosa ezilungiselelwe iimeko zenkonzo ethile, amaqhinga omatshini alungelelaniswa ne-graphite morphology, kunye nemigaqo yomgangatho eyilelwe uxanduva olubalulekileyo. Sisebenzela abathengi abafuna iintsimbi ezingwevu ezisebenza-hayi ukufika nje.
Ukujonga phambili, ugxininiso lwethu lwe-R&D luhlala lusekufezekisweni kokwenziwa komatshini: ukunciphisa ixesha elipheleleyo lokukhokela kwizindlu ezintsonkothileyo ngaphandle kokuncama imfezeko ye-microstructural. Ngenxa yokuba ukuqina akulinganiswa kwiminyaka kuphela. Kulinganiswa ngokuzithemba-rhoqo xa inkqubo inamandla.
