Ubonelelo lwefektri ye-QT450-10 ayisiyonto nje inkcazo-sisithembiso sokusebenza. Xa imizimba yevalve ye-hydraulic, i-pump housings, okanye i-winch center shafts kufuneka ixhathise ukudinwa phantsi komthwalo we-cyclic ngelixa ubambe ukunyamezela kwe-GD & T, i-QT450-10 i-ductile iron ihambisa ibhalansi efanelekileyo: i-450 MPa yamandla e-tensile, i-10% ubuncinci bobude, kunye nokuqikelelwa kobuchule emva kokufakwa. Kodwa ukufumana i-QT450-10 castings ayithethi malunga nokufumana * nayiphi na isiseko. Imalunga nokusebenzisana nomboneleli olawula isinyithi ukusuka kwiladle ukuya kwilathe-kwaye kulapho udibaniso oluthe nkqo luba lungenangxoxo.
Kutheni i-QT450-10 ifuna ngaphezulu kokuCasa okuMgangatho
Siye sabona iindawo ezintathu zokungaphumeleli eziqhelekileyo kwiiprojekthi ze-QT450-10: i-nodularity engahambelani ebangela ukuphuka kwangaphambi kwexesha kwiikona eziphezulu zoxinzelelo; ukugqwetheka okushiyekileyo okubangelwa luxinzelelo ngexesha lomatshini wokugqibela we-CNC; kunye ne-microcracks engaphezulu evezwe kuphela emva kovavanyo loxinzelelo. Ezi azenzi "iimpazamo." Ziyimpawu zokuqukuqela komsebenzi-apho ukuphosa, unyango lobushushu, kunye nomatshini kwenzeka kubathengisi abahlukeneyo abanenkqubo engafanelekanga yeefestile.
Iimpawu zemishini ye-QT450-10 ixhomekeke kulawulo oluchanekileyo lonyango lwe-magnesium, ixesha lokugonywa, kunye nesantya sokupholisa kwi-mold. Ukutenxa nge-3°C kwiqondo lobushushu lokugalela kunokutshintsha ukubalwa kwamaqhuqhuva ngama-20%. Yiyo loo nto isiqinisekiso sokulandelelwa kwezinto eziluhlaza sibalulekile-kungekhona njengamaphepha, kodwa njengekhonkco eliphilayo kwiingxelo zokuhlalutya i-ladle kunye neelogi zembali ye-thermal. Kwiziko lethu le-Qingdao, yonke ibhetshi ye-QT450-10 ithwala ukwakheka kweekhemikhali ezipheleleyo (C: 3.4–3.8%, Si: 2.2–2.8%, Mg: 0.03–0.06%), imivalo yovavanyo eqinileyo ephoswe ecaleni kwenxalenye yemveliso, kunye nobulukhuni bemephu kuwo wonke ubukhulu becandelo.
Oku akuyothiyori. Kunyaka ophelileyo, i-OEM yepompo yaseYurophu yatshintshela kuthi emva kokuba ababoneleli ababini bangaphambili bengaphumelelanga uzinzo kwizindlu zesilinda ezinamacandelo eludongeni angama-120 mm. Umthengisi wabo wokuqala wasebenzisa iimbumba zesanti kunye nezibophelelo zodongwe eziqhelekileyo-ezibangela ukupholisa okungalinganiyo kunye ne-pearlite banding. Sitshintshele kwintlabathi edibeneyo ye-resin kunye ne-venting elawulwayo kwaye songeza i-post-cast stress-relief kwi-580 ° C kwiiyure ze-4. Isiphumo: ukuguqulwa kwehle ukusuka ku-± 0.18 mm ukuya ku-± 0.06 mm-ngaphakathi kwendawo yabo yokunyamezela kwe-CMM.
Yintoni "Factory Direct" ithetha ngokwenene kubathengi be-QT450-10
Abanye ababoneleli bazibhale ngokuthi “i-QT450-10 ifektri” kuba banendawo esisiseko. Abanye bafumana eso sihloko kuba bengabanini bexabiso lonke-ukusuka kwi-alloy melting kunye nokuphosa ngokusebenzisa i-axis-axis milling, i-shot peening, kunye novavanyo lokuvuza kwe-helium. Umahluko ubonisa ukuhambelana kwexesha lokukhokela, isantya soyilo lokuphindaphinda, kunye nesisombululo sengcambu.
- Ukuphosa ukuya kumatshini ngesandla kwenzeka kwisakhiwo esinye: Akukho kulibaziseka kwamalungiselelo, akukho monakalo wokuphatha kwakhona, akukho lunxibelelwano malunga neereferensi zedatum.
- I-GD&T iqinisekisiwe phambi kokuba umatshini uqalise: Iqela lethu le-metrology lihlola iinxalenye ze-cast as-cast zisebenzisa i-scanners zokukhanya ezicwangcisiweyo-ukuthelekisa umphezulu wokwenyani ngokuchasene ne-CAD yegama ukulungelelanisa iindlela zezixhobo zokwahluka kwesitokhwe.
- Ukunyangwa kokushisa kuhlanganiswe, kungekhona ngaphandle: Siqhuba imigca yokucoca eqhubekayo kunye nerempu ecwangcisekileyo / i-soak / iiprofayili ezipholileyo, ezibekwe esweni nge-ASTM E2862 nganye, kunye neetshathi zomlilo ezigcinwe kwiqashiso ngalinye.
Oko kudityaniswa kunciphisa ukuguqulwa kweprototype ukusuka kwiiveki ze-12 ukuya kwi-5. Kwii-odolo zevolumu ephakathi (i-500-5,000 iipcs / ngonyaka), kuphelisa "i-foundry bottleneck" enyanzelisa abathengi ukuba babambe isitokhwe sokhuseleko seenyanga ezi-6. Omnye umthengi waseMntla Melika ucuthe ixabiso le-inventri nge-37% emva kokutshintshela kwimodeli yethu ye-QT450-10 ethe ngqo yefektri.
Xa i-QT450-10 Ayonelanga-kwaye Yintoni omele uyenze endaweni yoko
Ezinye iinjineli azigqibekanga kwi-QT450-10 kuzo zonke izicelo zentsimbi ye-ductile. Kodwa sicebisa ngenye indlela xa: ukushisa okusebenzayo kudlula i-300 ° C (ukubola kwepearlite kukhawuleza); ukugqoka ukuxhathisa kubalulekile (umzekelo, i-piston ring grooves); okanye i-corrosion exposure ibandakanya iikloridi okanye i-H₂S. Kwezo meko, i-QT500-7 inika amandla aphezulu kodwa i-ductility ephantsi-okanye i-cobalt alloy T800 ihambisa i-3 × ubomi bokugqoka kwi-650 ° C.
Nantsi into esiyenzayo endaweni yoko: sebenzisa itriage yezixhobo ngexesha lophononongo lobunjineli. Ukuba inxalenye ibona > i-200 MPa yoxinzelelo olutshintshanayo, silinganisa ubomi bokudinwa sisebenzisa indlela yoxinzelelo lwendawo kwi-nCode DesignLife. Ukuba ukuqina komphezulu kufuneka kudlule i-350 HB, sincoma amabakala e-austempered ductile iron (ADI) afana ne-ASTM A897 Grade 2. Ukuba ijometri ineembambo ezibhityileyo (<8 mm) ithande ukunciphisa i-porosity, sitshintshela kwi-investment casting-nokuba kwi-ductile iron-ukuqinisekisa ukuvakala.
Oku akumangalisi. Ithintela ukusilela kwintsimi. Sinqabile i-17 QT450-10 iikowuti kwiinyanga ezili-18 ezidlulileyo kuba isicelo sifune enye into. Ukuthembela kuqala apho.
Ukukhetha iQT450-10 Iqabane lakho: Iitshekhi ezintathu ezingaxoxiswanga
Phambi kokusayina i-NDA, buza le mibuzo-kwaye ufune ubungqina:
- Ngaba ungandibonisa iingxelo ezintathu zokugqibela zokuhlalutya i-ladle ye-QT450-10? Ayizozatifikethi kuphela-eziprintiweyo eziprintiweyo ezinesitampu sexesha, i-ID yomsebenzisi, kunye nelogi yokulinganisa i-spectrometer.
- Ngaba uyalwenza uvavanyo lwe-ultrasonic kwi-castings engaphezulu kwe-50 mm? I-ASTM A609 iNqanaba 3 isemgangathweni kumacandelo abalulekileyo oxinzelelo. Ukuba bathi “ngesicelo kuphela,” hamba.
- Yeyiphi imeko yakho embi kakhulu yeCpk yokuqina kwe-QT450-10 kwiinyanga ezili-12 ezidlulileyo? Nantoni na engaphantsi kwe-1.33 ithetha ukungazinzi kwamanani. Okwethu yi-1.68.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwifektri ye-QT450-10 eyakhelwe i-mission-critical parts-hayi i-commodity castings. Asigcini izithuba ezingenanto eziqhelekileyo. Sivelisa iindibano ezisebenzayo: iivalve zoxinzelelo kunye neendawo zokuhlala ezidibeneyo, iziseko zempompo ezinemingxuma yokuxhoma kwangaphambili, i-winch shaft rollers kunye ne-raceways eqinile-konke ukusuka kwi-single-pour QT450-10 castings. Olo gxininiso lusenza ukuba siphucule iinkqubo abanye abangayijongiyo: ulawulo lwe-graphite morphology ngokusebenzisa izitofu ezinqabileyo zomhlaba, i-vibration-assisted degassing ukunciphisa i-hydrogen porosity, kunye ne-in-process nodularity verification usebenzisa uhlalutyo lomfanekiso oluzenzekelayo.
Inyathelo elilandelayo ayikucela ukowuta. Ithumela umzobo wakho ngempendulo yokwenziwa-ngaphandle kweentambo ezincanyathiselweyo. Kuba eyona QT450-10 yokubonelela iqala phambi kokugalelwa kokuqala.
