Utyalo-mali olusetyenziselwa iinxalenye zoomatshini bobunjineli ayisiyondlela yokuvelisa kuphela-yeyona ndlela isebenzayo xa uzinzo lwe-dimensional, imfezeko ye-microstructural, kunye nokuthembeka komphezulu kufuneka kusinde kwi-300+ bar hydraulic pulses okanye ukunxitywa kwe-abrasive eqhubekayo kwi-winch shafts. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphose ngaphezulu kwe-12,000 AMS 5387 cobalt alloy pump housings ukususela ngo-2019. Wonke umntu uphumelele i-100% yokuqinisekisa i-CMM kwi-± 0.05 mm GD & T callouts-kunye ne-zero ayiphumelelanga uvavanyo loxinzelelo olusebenzayo kwi-1. Oko kuhambelana akwenzeki ngengozi. Kwenzeka xa ukuchithwa kotyalo-mali kungaphathwa njengenkqubo, kodwa njengesiganeko esilawulwayo se-metallurgical.
Kutheni ukuCalwa koTyalo-mali kuphumelele apho ukuphosa kwesanti kusilela-Ngalo lonke ixesha
Amacandelo oomatshini bobunjineli asebenza phantsi kwemiqathango engenakuxoxisana: izindlu ze-piston pump cylinder zifuna ukuchaneka kwe-contour yangaphakathi ngaphakathi kwe-0.08 mm ukukhusela i-cavitation; imizimba yevalve yoxinzelelo ifuna ukuvuza kokuqina kodonga olungaphantsi kwe-4.2 mm ngaphandle kwe-porosity; iirola ze-winch centre shaft zinyamezela imithwalo ejikelezayo engaphaya kwe-18,000 N·m ngelixa zijikeleza nge-65 rpm kwiindawo ezinothuli. Ukugaywa kwesanti akukwazi nje ukuhambisa loo ndibaniselwano. Ibhendi yayo yokunyamezela eqhelekileyo yi ± 0.5 mm. Uburhabaxa bayo bomphezulu buphakathi kwe-Ra 12.5 μm-irhabaxa kakhulu xa isetyenziselwa ukutywina. Kwaye ukwakheka kwayo okuziinkozo akunalo ulawulo oluya ngqo, imema i-micro-shrinkage voids kufutshane nezinyuka zoxinzelelo olubalulekileyo.
Utyalo-mali lusisombulula zontathu. Ngeembumba ze-ceramic ze-ceramic ezakhiwe kwiipatheni ze-wax ezichanekileyo, sibamba i-± 0.15 mm kwiimpawu ukuya kwi-600 mm-ziqinile kunezibonelelo ezininzi zokugqiba i-CNC. Ukugqitywa komphezulu kubethe iRa 2.5–4.0 μm njengokuphoswa, kuphelisa ukucola okusesibini ebusweni bokutywina. Okona kubaluleke kakhulu, iiprofayili zethu ezilawulwayo zokuqinisa-eziphunyezwe ngokulungiswa kwe-gating, i-shell preheat, kunye neendawo zokupholisa eziko-zivelisa izinto ezintle, ezilinganayo ze-dendritic kwi-alloys esekwe kwi-T800 cobalt. Sikuqinisekisile oku ngohlalutyo lwe-metallographic kwii-heats ezingama-47 ezilandelelanayo: ubungakanani beenkozo bahlala be-ASTM 6-7 kwimida yebhetshi, ehambelana ngokuthe ngqo ne-22% yobomi obuphezulu bokudinwa kuvavanyo olukhawulezayo lwe-winch shaft.
Ukudityaniswa okuthe nkqo ayisiyonto iBuzzword-Yi-inshurensi yakho yoMda
Abanye ababoneleli bangaphandle kokuphosa, ukwenza oomatshini, kunye nonyango lobushushu. Asazi. Kwiziko lethu le-Qingdao eliqinisekisiweyo le-ISO 9001, lonke icandelo le-AMS 5387 liqukuqela kulandelelwano olunye olulawulwayo: imathiriyeli ekrwada eqinisekisiweyo → i-vacuum-arc enyibilikisiweyo ingot → utyalo-mali → isiqabu soxinzelelo → i-axis emihlanu ye-CNC ukuhombisa → ukujongwa kwedayi egcweleyo ye-CMM. Kutheni ibalulekile nje loo nto? Ngenxa yokuba ukwanda kwe-thermal kungahambi kakuhle phakathi kokusalwa kunye noomatshini kubangela i-warpage efihliweyo. Sayilinganisa: iinxalenye ezenziwe ngoomatshini iiyure ezingama-72 emva kokuphoswa kwabonisa i-0.032 mm isaphetha kwi-320 mm span. Xa wenziwe ngoomatshini kwiiyure ezi-4 zokupholisa okulawulwayo? I-Bow yehla ukuya kwi-0.007 mm-ngaphakathi kwe-speccal esebenzayo ye-rotors ye-speed pump.
Oku kudityaniswa kwakhona kuphelisa izithuba zokulandela umkhondo. Iqashiso ngalinye liphethe iicerts zemathiriyeli ezigcweleyo (MTRs), iilogi zembali eshushu, kunye nokulungelelanisa iingxelo zomlinganiselo. Xa i-OEM yaseYurophu ichaza ukunxitywa kwesihlalo sevalve kwangaphambi kwexesha, siye sayilandela-hayi kwi-alloy chemistry-kodwa kwiqondo lokushisa elingaguqukiyo lokutshisa iqokobhe kwishifti enye. Silungelelanise iprofayile yesithando somlilo, ukuqinisekiswa kwakhona, kwaye sahambisa iindawo ezitshintshileyo ngeentsuku ezili-11. Akukho ukukhomba ngeminwe komntu wesithathu. Akukho kulibaziseka okubangelwa yingcambu yeentsuku ezingama-45.
Ukusebenza kwehlabathi lokwenyani kubetha iiNgcaciso zePhepha-Ngalo lonke ixesha elinye
Abathengi bayabuza: "Ngaba utyalo-mali lwakho luyakwazi ukumelana ne-450 ° C ukuvezwa okuthe gqolo kwi-oyile kunye nezixhobo zerhasi?" Siphendula ngedatha-hayi iincwadana. Imilomo yethu yealloyi ye-T800 iqhube iiyure ezili-1,840 kwiimeko ezilinganisiweyo zentloko yequla phambi kokubonisa ukhukuliseko olunokumetwa. Ukhuphiswano lwesanti-cast elinganayo ayiphumelelanga kwiiyure ezingama-620. Umehluko? Ukungabikho kokuphoswa kotyalo-mali kokukhanya komgca wokungunda kunye nokuhanjiswa okuphezulu kwe-interdendritic carbide.
Sikwalandelela iindlela zokungaphumeleli. Ngo-2023, i-92% yamacandelo anqatshiweyo avela kwimiba enxulumene noyilo-kungekhona iimpazamo zenkqubo. Amacala aqhelekileyo: iifayili eziyilwe ngaphantsi ezibangela uxinzelelo lwengqondo, utshintsho olungaxelwanga-ngondoqo kumacandelo amancinci, okanye i-GD & T callouts engahambelani nokuziphatha kwe-ceramic shell shrinkage. Yiyo loo nto uphononongo lwethu lobunjineli lubandakanya impendulo yasimahla yokwenziwa kwengxelo-imingcipheko efana ne "Olu donga lwe-0.8 mm luya kuqhekeka ngexesha lokukhupha" okanye "Loo ± 0.02 mm ukunyamezela isikhundla kufuna ukulungiswa kwe-CNC emva kokuphosa." Siyibamba ngaphambi kokuba ipateni yokuqala ye-wax isikwe.
Iphothifoliyo yethu iyayingqina: iivalvu zoxinzelelo ze-hydraulic excavators, izindlu ze-cylinder kwiimpompo zodaka lwe-triplex, iziseko zempompo zeeyunithi ze-offshore desalination, kunye ne-winch center shaft rollers ye-50-toni yezithuthi zemigodi-zonke zenziwe ngokuphosa utyalo-mali, zonke zihanjiswa kwishedyuli, yonke intlanganiso ye-ASME B16.34, i-protocol esebenzayo yomthengi-i-ISO428.
Ukukhetha i-Right Investment Casting Partner kuthetha ukubuza imibuzo enzima
Sukubuza "Ngaba uyakwenza utyalo-mali?" Buza "Uwulawula njani umahluko weqokobhe lobukhulu ngapha kwepatheni ye-450 mm?" Okanye “Loluphi ubungakanani bakho obuphezulu obuvumelekileyo bokubandakanywa kwi-ASTM E45 ye-AMS 5387?” Okanye “Ndibonise iingxelo zakho zokugqibela zeCMM zenxalenye ene-≥12 GD&T callouts.”
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, sipapasha ezo mpendulo-kungekhona kwiidekhi zokuthengisa, kodwa kwiirekhodi zemveliso. Sityala imali kwiiCMM zodidi lwe-metrology ezineetafile zegranite ezihlawulelwe ubushushu, hayi izikena zedesktop. Silinganisa yonke i-thermocouple ye-furnace yonke imihla-hayi ngeveki. Sigcina iisampuli zezinto eziluhlaza iminyaka eyi-10-kungekhona iinyanga ezi-6.
Utyalo-mali lotyalo-mali kumatshini wobunjineli amacandelo ayingokufumana umthengisi. Imalunga nokukhusela ulwandiso lobuchwephesha lweqela lakho lobunjineli-elinye lithetha kakuhle ngesinyithi, i-GD&T, kunye nefiziksi yokwenyani yehlabathi. Lo ngumgangatho esidibana nawo. Ngalo lonke ixesha.
