Intsimbi yentsimbi yeHT250 ayilolinye ibakala kuluhlu-ngumqolo we-hydraulic manifolds, izindlu zempompo, kunye neefreyimu zenkqubo yewintshi ekufuneka ibambe uzinzo lwedimensional phantsi kwemijikelo yoxinzelelo lwebar engama-350. Xa umthengi waseJamani wasithumelela umzobo wezindlu zepiston pump cylinder-HT250, ±0.02 mm GD&T callouts, umphezulu ogqityiweyo Ra 1.6 µm-asizange siqale ngokucaphula. Saqala ngokuqinisekiswa kwe-metallurgical: ukuqinisekiswa kwe-carbon equivalent (CE = 4.12), ukuqinisekisa umxholo we-pearlite ≥85% ngohlalutyo lwe-micrograph, kunye nokujonga ubulukhuni beBrinell kwiindawo ezintathu (192-208 HBW). Yileyo ndlela Imveliso yeHT250 ufumana ukuthenjwa—kungekhona ngokudwelisa iziqinisekiso, kodwa ngokubambelela kwisigqibo ngasinye kwindlela yokuziphatha ngokwezinto eziphathekayo.
Kutheni i-HT250 ifuna ngaPhantsi kuneMgangatho wokuSebenzisa iFoundry
Uninzi lwababoneleli baphatha i-HT250 "njengentsimbi engwevu." Kodwa iindlela zokusilela zehlabathi zokwenyani zibalisa ibali elahlukileyo. Siye sabona izindlu ze-cylinder ziqhekeka kumalungu e-flange emva kweeyure zokusebenza ze-14,000-kungekhona ukusuka ekugqithiseni, kodwa ukusuka ekuhanjisweni okungahambelaniyo kwe-graphite nodule ngexesha lokuqina. Kwimeko enye, umenzi wezixhobo ze-oyile yaseMntla Melika walile i-12% yebhetshi kuba iibhendi ezityebileyo ze-ferrite zenziwe kufutshane namaphiko okupholisa, ziwisa amandla e-tensile yendawo ngaphantsi kwe-250 MPa. Yiyo loo nto wethu Imveliso yeHT250 ilawula izinto ezintandathu ezibalulekileyo ngaphambi kokugalela: ubushushu obunyibilikayo (1,480-1,510 ° C), ixesha lokugonywa (ngaphakathi kwemizuzwana engama-90 emva kokucofa), ixesha lokuhlala ladle (Udibaniso oluthe nkqo luSombulula oko kuqhawuka kuKhuseleko lwangaphandle
Abanye abathengi bafumana umthombo wokuphosa kumthengisi omnye, umatshini osuka komnye, unyango lobushushu ukusuka kwisithathu. Loo modeli iyasilela kwi-HT250. Ngoba? Ngenxa yokuba uxinzelelo lwentsalela olubangelwa ngoomatshini lusebenzisana ngokungalindelekanga kunye ne-microstructure. Silinganise ukuya kuthi ga kwi-45 µm ukugqwetheka kumatshini we-HT250 wevalve yemizimba xa ukurhabaxa kunye nokugqitywa kusenziwa kwiindawo ezahlukeneyo-kwanakwiindlela zesixhobo ezifanayo. Kwiziko lethu, ukuphosa, ukunciphisa uxinzelelo, umatshini we-CNC, kunye nokuhlolwa kokugqibela kwenzeka phantsi kophahla olunye. Sisebenzisa i-CMM efanayo ekuqinisekiseni ukuphosa okungenayo kunye nokusayina inxalenye yokugqibela-ukususa iimpazamo zokutshintsha kwedatum. Ngomyalelo wamva nje we-winch ye-winch center shaft rollers, olu hlanganiso lwehlise ixesha elipheleleyo lokukhokela ngama-37% kwaye kunciphisa ukukhatywa kwenqaku lokuqala ukusuka kwi-11% ukuya kwi-zero. Umahluko yayingengoomatshini abakhawulezayo. Yayilawulwa yimbali ye-thermal kunye ne-metrology edibeneyo.
Intsebenzo ye-HT250 yokwenyani yehlabathi iqala ngoLuleko lweMathiriyeli ekrwada
"I-HT250 eqinisekisiweyo" ayithethi nto ngaphandle kokulandeleka. Siyakwala ukunyibilika okusekwe kwi-scrap kumacandelo abalulekileyo. Yonke i-HT250 yokugalela isebenzisa ≥75% intsimbi yehagu enyulu (esuka kwizinyibiliki eziqinisekisiweyo zaseTshayina naseKorea), icoke enesulfure ephantsi (<0.3% S), kunye ne-ferrosilicon inoculants ene-≤0.02% ye-aluminium. Ubushushu ngamnye buphethe ingxelo epheleleyo ye-spectrographic-ikhabhoni, i-silicon, i-manganese, isulfure, i-phosphorus, i-chromium, i-molybdenum-kwaye sigcina ii-micrographs zedijithali kwiqashiso ngalinye. Xa i-OEM yempompo yaseMzantsi-mpuma ye-Asia idinga i-AMS 5387 cobalt alloy parts *kunye ne* HT250 iziseko zendibano enye, siye sangqamanisa ulwandiso lwe-thermal coefficients kuzo zombini izixhobo-hayi ngokuqagela, kodwa ngokuqhuba iimvavanyo zedilatometry ezinxuseneyo. Yiloo ndlela ingqibelelo yokusebenza eyakhiwa ngayo kwinkqubo-ayiyongezwa kamva.
Ukukhetha Umzi-mveliso wakho weHT250: Iitshekhi ezintathu ezingaxoxiswanga
- Buza iingxelo ze-microstructure-hayi nje amanani obunzima. Umthengisi we-HT250 wokwenyani ubonisa i-pearlite %, uhlobo lwegraphite (A-E nge-ASTM A247), kunye nezithuba phakathi kwe-interdendritic-hayi nje "ukudibana ne-ISO 185."
- Funa ubungqina bolawulo lwe-dimensional ekwinkqubo. Ukuba balinganisa kuphela iindawo ezigqityiweyo, buza apho bajonga khona ukushwabana ngexesha lokupholisa. Sifaka ubushushu bebhokisi engundoqo, ukufuma kokungunda, kunye nedatha yokupholisa igophe kuyo yonke imveliso eqhutywayo.
- Qinisekisa isakhono se-GD&T kumphezulu wecast. Ngaba i-CMM yabo iyakwazi ukuphonononga iimpawu zedatum? Ngaba basebenzisa ii-optical compators kwiiprofayili ezinzima? Siqinisekisa izibonelelo zokuphosa ngokuchasene ne-CAD ngaphambi komatshini-kuba ukusebenzela kwakhona kwi-HT250 kubiza i-3.2 × ngaphezulu kunentsimbi.
An Imveliso yeHT250 ayichazwanga yicupola okanye umgca wokubumba. Ichazwa ngendlela ephendula ngayo imibuzo malunga ne-graphite morphology, indlela yokusingatha ukunyamezela kwe-0.05 mm kwi-400 mm casting, kunye nokuba iphatha umzobo wakho njengenkontileka yokuvelisa-okanye isiqalo sengxoxo yobunjineli. Asithumeli iinxalenye zeHT250. Sithumela ngenqanawa ukuqhubeka kolwakhiwo-ukusuka kwisinyithi esinyibilikisiweyo ukuya kwinkonzo ecinezelekileyo. Yiyo kuphela i-metric ebalulekileyo xa ukungaphumeleli kungeyona inketho.
