Xa iinjineli zicacisa izisombululo zefektri yokuphosa isinyithi, azithengi nje iinxalenye-zigcina imfezeko yolwakhiwo phantsi koxinzelelo lwe-hydraulic yeebha ezingama-350, ukuzinza komda emva kokuhamba ngebhayisikile yobushushu, kunye nokunganyangeki kwiindawo ezinodaka oluludaka. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye saphosa phezu kwe-12,000 yentsimbi yezixhobo ze-piston pump cylinder housings ukususela ngo-2021-nganye ihlolwe kunye ne-Zeiss CMMs ukuya ku-± 0.015 mm GD & T tolerances. Ayingomthamo lowo. Kukuqinisekisa.
Kutheni le nto i-Iron Casting isilela-kwaye iNqanda njani ukuCalwa ngokuchaneka kwayo
Uninzi lweentsilelo zentsimi zibuyela emva kwizithuba ezithathu ezinokuphepheka: i-graphite morphology engahambelani, uxinzelelo olushiyekileyo olusuka ekupholiseni okungalinganiyo, kunye ne-microcracks eyenziwe ngomatshini kumacandelo anodonga oluncinci. Oku sikubonele mathupha kwizindlu zevalve ye-OEM yaseYurophu-yaliwe kabini ngenxa ye-porosity kwindawo yokungena. Unobangela weengcambu? I-Sand mold permeability ayihambelani kwaye akukho post-cast isiqabu kuxinzelelo phambi kokuba i-CNC ijike. Ukulungiswa kwethu: I-ASTM A48 Iklasi ye-35 yentsimbi ye-grey kunye ne-graphite ye-flake elawulwayo (Uhlobo D), ilandelwa yi-subcritical annealing kwi-680 ° C kwiiyure ze-4. Isivuno siphucuke ukusuka kuma-62% ukuya kuma-98.7%.
Lowo ngumahluko phakathi kokuphosa kunye ethembekileyo ukuphosa intsimbi. Ukuthembeka kuthetha ukuhlangabezana ne-ISO 8062 yokunyamezelana kwejometri ngaphandle kokusila okwesibini. Kuthetha ukubamba i-0.05 mm flatness kwisiseko sempompo ye-320 mm × 210 mm emva kweeyure ezingama-72 zovavanyo lokungcangcazela. Kuthetha ukuqinisekiswa kwebhetshi nganye ngokuchasene ne-ASTM E1245 yokuqukwa komxholo-kwaye ukwala imathiriyeli ukuba iintambo zesulfide zingaphezu kwe-1.5 µm ubude.
Izakhono ezine ezingaxoxisiyo zeMishini ye-Iron-Critical Parts
Umzi-mveliso wokwenyani wokugalela intsimbi kufuneka uhambise ngaphezu kwentsimbi egaliweyo. Nantsi into esiyivavanya yonke imihla:
- Ulawulo lweMetallurgical: Intsimbi ekrwada ifunyenwe kuphela kubaboneleli abaqinisekisiweyo abaneengxelo ezipheleleyo zokuhlalutya i-ladle-elingana nekhabhoni ebanjwe ngaphakathi kwe-± 0.03, ukuhluka kwe-silicon kufakwe kwi-± 0.05%
- Inkqubo-edibeneyo yonyango lokushisa: Akukho kukhutshwa ngaphandle kwendawo. Isiqabu soxinzelelo, ukuqheleka, kunye nokufakwa ngaphakathi kwendlu kusetyenziswa iziko elicwangcisiweyo ngokugawulwa kwe-thermocouple ngexesha lokwenyani
- Ukuphosa ukuya kumatshini ukuchaneka kwesandla: Ukulungiswa komatshini okuyilwe ukusuka kwidatha yolungelelwaniso-hayi-hayi imizobo-ukuhlawula iivektha zokuncipha ezinokuqikelelwa.
- Ukulandeleka kwebhetshi epheleleyo: Inxalenye nganye iphethe ikhowudi ye-QR edibanisa kwilogi yayo yokunyibilika, ingxelo yokwakheka kwesanti, iskena seX-ray, kunye nesatifikethi sokugqibela sokuhlolwa kweCMM.
Asiyibizi ngokuba "kukuphosa + ukusebenza ngomatshini." Siyibiza ukuqhubeka komda. Xa i-winch center shaft roller ifuna i-42 HRC yobulukhuni bomphezulu kunye ne-0.008 mm yokuphuma kwijenali ye-120 mm, awukwazi ukunyamezela ukupakisha phakathi kwe-Foundry kunye nevenkile yomatshini.
Apho kuyeka ukuphoswa kwentsimbi okuMgangatho-Kwaye isicelo sakho sifuna ngakumbi
I-Grey Standard okanye i-ductile iron isebenza-kwi-brackets static, izindlu ezingenaxinzelelo, izicelo eziphantsi. Kodwa xa abathengi becela ukufakwa kwe-AMS 5387 cobalt alloy *kwintsimbi yokuphosa, okanye imilomo esekwe kwi-T800 exhonywe ngqo kwintloko yempompo yentsimbi, kulapho uninzi lweefektri zokuphosa intsimbi ziyathandabuza. Asazi.
Isisombululo sethu: hybrid casting-machining. Sijula umzimba wentsimbi ngeepokotho ezenziwe ngoomatshini ngokuchanekileyo, emva koko siqhoboshele okanye sicinezele ukufakwa kwe-alloy ephezulu *phambi* kokugqibela komatshini. Ngoba? Ngenxa yokuba ukwanda kwe-thermal ukungalingani phakathi kwe-cobalt alloys kunye nentsimbi kudala i-microgaps phantsi kwebhayisikili ye-thermal-ngaphandle kokuba ulawula i-geometry yojongano kwinqanaba le-micron. Sinikezele ngeentlobo ezili-17 zolu lungelelwaniso kwiindibano zempompo yodaka kunye ne-oyile esebenza kwi-180 ° C kunye ne-220 bar pulsating load.
Obo buchule abongezwanga-buyinjineli kuyilo lwethu loncedo. Imigca yokuphosa yesanti ihlala kufuphi neeseli ze-CNC ze-multi-axis. Ii-oveni zokuphatha ubushushu zitya ngqo kwizikhululo ze-optical metrology. Akukho kulibaziseka kwamalungiselelo. Akukho msantsa wamaphepha. Itsheyini yenkqubo enye nje.
Ukukhetha i-Iron Casting Factory yakho: Yintoni omawuyiqinisekise phambi kokusayina
Buza le mibuzo mihlanu-kwaye ufune ubungqina, hayi iincwadana ezinemifanekiso:
- Ngaba ungandibonisa iingxelo ezintathu zokugqibela zeCMM zenxalenye ehambelana nedatha ebalulekileyo yomzobo wam?
- Oluphi ubungakanani bobukhulu bodonga olugqithileyo kwi-500 mm × 300 mm ukuphosa-kwaye ululinganisa njani?
- Ngaba wenza uvavanyo lwe-ultrasonic kuzo zonke ii-iron castings ezingaphezulu kwe-25 kg? Ukuba akunjalo, kutheni?
- Ukuqinisekisa njani ukuhambelana kolwakhiwo lwegraphite ngapha kokugalelwa kweetoni ezi-2? Imifanekiso ye-SEM okanye imephu yobuncinci?
- Xa i-GD&T yam ifuna unyamezelo lwendawo kumngxunya we-Ø12 mm ngokunxulumene nomphezulu wedatum—ngaba uyawumatshini lo mngxuma kwisetingi enye, okanye uwumise ngokutsha?
Ukuba iimpendulo azikho ngqo-okanye "iinkqubo eziqhelekileyo" ngaphandle kokukhankanya imigangatho-sincoma ukuba uhambe. Iifektri zokwenyani zentsimbi zithetha ngamanani, hayi izibizo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ukusuka eQingdao-kungekhona njengenkampani yokurhweba, kodwa njengeqabane lokuvelisa kunye ne-ISO 9001-certified casting, machining, kunye nokuhlola ukuhamba komsebenzi phantsi kophahla olulodwa. Asikhupheli ngaphandle iinkqubo ezingundoqo. Asiphazamisi i-metallurgical specs ngesantya sokuhanjiswa. Kwaye asiyiphathi indlu yevalve yoxinzelelo njengentsimbi yempahla.
Ngenxa yokuba iindawo ezithembekileyo zetsimbi ziqala ixesha elide ngaphambi kokuthulula. Baqala ngokwazi ngokuthe ngqo apho uxinzelelo luya kugxila khona-kunye nokuyila ukuphosa, umjikelo wobushushu, kunye nendlela yomatshini yokuhlangabezana nayo.
