Xa iinjineli zicacisa ukuphoswa kwentsimbi engwevu kwiivalvu zehydraulic okanye iimpompo zezindlu, azikhethi nje izinto eziphathekayo-zibheja ngokuzinza kwe-dimensional phantsi kwe-thermal cycling, i-damping engaguqukiyo kwiinkqubo zokungcangcazela, kunye nokuziphatha okuxekekileyo kokunxiba emva kwe-10,000 + iiyure zokusebenza. Yiyo loo nto ukhangelo lwe Umzi-mveliso wenkampani yokuphosa intsimbi engwevu kunqabile ukuba iqale ngexabiso-kwaye phantse isoloko iphela ngolawulo lwenkqubo, ukulandeleka kwe-metallurgical, kunye nonyamezelo lwe-zero lwe-micro-shrinkage kwiindlela zomthwalo obalulekileyo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza enye into enjalo e-Qingdao-kungekhona njengesiseko esiqhelekileyo, kodwa njengeqabane elichanekileyo elihlanganisiweyo lecandelo apho yonke intsimbi engwevu ifumana uqinisekiso olupheleleyo lwe-batch-level chemistry ngokuchasene ne-ASTM A48 Class 30B kunye neenkcukacha ze-EN-GJL-250. Siye sabona abathengi bebuyela uku-odola izindlu zesilinda sempompo yepiston emva kweminyaka emithathu-hayi ngenxa yokuba iinxalenye ziye zasilela, kodwa ngenxa yokuba ibhetshi yabo yokuqala ka-2021 isadibana ne-GD&T callouts ngaphakathi kwe-± 0.015 mm kwiimpawu ze-datum ezili-12. Oko kuhambelana akuzenzekelanga. Ibhakwa kwiiprothokholi zentlawulo yesithando somlilo, iilogi zoxinzelelo lokubumba, kunye nemijikelo yokuphoswa koxinzelelo lwasemva koxinzelelo olulinganisiweyo ngenxalenye yobunzima kunye nobukhulu becandelo.
Yintoni eyahlula oku Umzi-mveliso wenkampani yokuphosa intsimbi engwevu ukusuka kubathengisi abagxile kumthamo? Iinyani ezintathu zokusebenza:
- Ukufumana izinto eziphathekayo akunakuxoxiswana: Zonke iibhetshi zentsimbi ezingwevu ziqala ngentsimbi yehagu eqinisekisiweyo evela kwi-ISO 9001 smelters-akukho ngxube ye-scrap ngaphandle kohlalutyo lwe-spectral. Ubushushu ngamnye buphethe ingxelo yovavanyo lokusila (MTR) ebotshelelwe kwinombolo yayo yokuphosa, kunye nemivalo yokuqina iyatsalwa kwaye ivavanywe phambi kokuba kuqale naluphi na umatshini.
- Ukuphosa akukwahlukaniswanga-kuyilwe ngokubambisana noomatshini: Izibungu zesanti zibandakanya izibonelelo zobuchule ezisekelwe kwiindlela zokugqibela zeCNC. Ngokomzekelo, i-winch centre shaft roller ifumana ii-angles eziqulunqiweyo zendawo kuphela apho izixhobo zokugaya zifikelela khona; kwenye indawo, umphezulu uhlala unje-iphoswe ukugcina ingqibelelo ye-graphite flake kunye nomthamo wokudambisa. Le ndlela yokucinga ixubeneyo inciphisa ixesha elipheleleyo lokukhokela ngama-22% ngokomndilili ngokuchasene nokucaphula ngokulandelelanayo.
- Ukuhlola akusiyo ukugcinwa kwesango-yimpendulo: Yonke into eyenziwayo idlula kwisikhululo seZeiss CONTURA CMM phambi komatshini okhohlakeleyo. Ukutenxa akurekhodwa nje-zibangela uphononongo lwengcambu kunye neenjineli zesiseko. Umcimbi omnye womthengi oqhubekayo wokungalungelelani kakuhle ulandelelwe emva kokuphambuka okuphambili koshicilelo ngexesha lokushukuma. Ukulungiswa? Ulandelelwano oluhlaziyiweyo lwebhokisi yombambo-hayi lutshintsho loyilo.
Abanye banokuphikisa ukuba i-iron engwevu "yimpahla yelifa" -egqunywe yi-ductile iron okanye isinyithi somgubo kwizicelo zoxinzelelo oluphezulu. Kodwa kukuthunyelwa kwehlabathi lokwenyani, ibambe izibonelelo ezahlukileyo: ukungcangcazela okuphezulu kwiziseko zempompo, ixabiso eliphantsi-nge-intshi nganye ye-cubic-intshi yezindlu ezikwicandelo elikhulu, kunye nobungqina bokunganyangeki kokudinwa kwe-oyile kunye nemizimba yevalvu yegesi evezwe ngokukhawuleza kwe-50 ° C-200 ° C ukukhwela ibhayisekile. Apho i-iron ductile cracks iqhekeka phantsi komothuko ophindaphindiweyo we-thermal, i-iron engwevu ihlala ivelisa ii-microcracks ezizinzileyo, ezikwaziyo ukuzikhawulela ezinokuthi zingakwazi ukwanda. Siye sakuqinisekisa oku kwimizimba yevalvu yoxinzelelo efunyenwe entsimini evela kumaqonga oLwandle lwaseNyakatho-isasebenza emva kweminyaka eli-17, ngaphandle kokugquma komhlaba.
Eli ziko lixhasa iindlela zokuphosa ezimileyo kunye ne-centrifugal, kodwa kumacandelo afuna ulawulo olungqingqwa eludongeni-njenge-AMS 5387 cobalt alloy alloy alloy parts agxunyekwe ngokuthe ngqo kwii-iron manifolds ezingwevu-ugxininiso luhlala ekugalweni kwesanti kunye nokubunjwa okubotshwe yiresin. Ngoba? Ngenxa yokuba ihambisa inkululeko yejometri efunekayo kwiitshaneli zokupholisa zangaphakathi, abaphathi abanyukayo, kunye ne-grooves edibeneyo yokutywina-konke kukugalela okukodwa. Akukho udibaniso welds. Akukho ndledlana zivuzayo. Akukho nkqubo yokujoyina yesibini ebeka esichengeni ukuqhubeka kolwakhiwo.
Kumaqela okuthenga avavanya a Umzi-mveliso wenkampani yokuphosa intsimbi engwevu, buza le mibuzo phambi kokuba utyikitye i-NDA:
- Ngaba unokubonelela nge-MTRs kunye nedatha yobulukhuni bobushushu obuthathu bokugqibela obusetyenziswa kwinombolo yethu yenxalenye?
- Uqinisekisa njani i-graphite morphology-kwaye yintoni i-rejection yakho yokwala i-Type D (ehlanjululweyo) iiflakes kwiindawo ezibalulekileyo?
- Ngaba iingxelo zakho zokuhlola ziquka idatha ye-CMM ye-point-cloud-ingekho nje ukudlula / isishwankathelo sokusilela?
- Loluphi utshintsho lwakho oluvumelekileyo lokugalela ubushushu kwiseti yokungunda enye?
IQINGDAO QIANGSENYUAN TECHNOLOGY iphendula ngokuthi ewe kuzo zone—ngobungqina obubhaliweyo. Ukuhamba komsebenzi wabo ohambelana ne-ISO akuyeki ukuphosa. Yandisa ngokuqinisekiswa konyango lobushushu (apho kuchaziwe), i-CNC ye-multi-axis igqiba nge-probing yenkqubo, kunye novavanyo olusebenzayo njengokuhlola uxinzelelo lwe-hydrostatic kwi-1.5 × uxinzelelo lokusebenza. Yonke into ethunyelwayo ibandakanya idosi enokulandeleka: ilog enyibilikayo, ingxelo yeX-reyi (ukuba iyafuneka), inguqulelo yenkqubo yomatshini, kunye nesatifikethi sokugqibela sokuhlolwa esisayinwe yi-QA lead.
Oku akukona malunga nokunyusa imveliso-imalunga nokuthembeka kokulinganisa. Njengoko ubomi bezixhobo zoshishino bunwenwela ngaphaya kweminyaka engama-25 kunye nokutshintshwa kwenxalenye yokuphelelwa lixesha iba ngumngcipheko wenqanaba eliphezulu, ixabiso Umzi-mveliso wenkampani yokuphosa intsimbi engwevu ephatha isakhelo ngasinye njenge-asethi elandelelanisiweyo-hayi into yorhwebo-iyanyuka kuphela. Isizukulwana esilandelayo seenkqubo ze-hydraulic asiyi kufuna amandla amaninzi. Bafuna ukuqikelelwa ngakumbi. Kwaye oko kuqala ixesha elide ngaphambi kokuba i-ladle yokuqala ithulule.
