Xa iinjineli zichaza 304 intsimbi engenasici kwi-valve ye-hydraulic, i-pump housings, okanye i-winch ye-offshore, abakhethi nje izinto eziphathekayo-bazibophelela ekuxhathiseni ukubola, ukuzinza kwe-dimensional, kunye nokuthembeka kwexesha elide phantsi koxinzelelo. Kodwa ukufumana loo mathiriyeli akwanelanga. Eyona nto ibalulekileyo yindlela eguqulwa ngayo: ingqibelelo yokuphosa, ukuchaneka kwe-CNC, ukungaguquguquki kwonyango lobushushu, ukulandeleka kwayo yonke ibhetshi enyibilikayo. Kulapho kuyinyaniso I-304 yefektri yensimbi engenasici iyazahlula-kungekhona ngamanani ekhathalogu, kodwa ngoqeqesho lwenkqubo.
Kutheni "iFactory" ithetha ngaphezu kweMizila yeMveliso nje
A I-304 yefektri yensimbi engenasici kufuneka ilawule ikhonkco elipheleleyo: iibhilethi eziqinisekisiweyo eziluhlaza kunye neengxelo zovavanyo lwe-mill (ASTM A240, EN 10088-2), umoya olawulwayo onyibilikayo we-sulfure ephantsi kunye ne-oxygen residuals, kunye nokwahlula okungqongqo ngexesha lomatshini ukuthintela ukungcoliswa kwe-carbon okanye izixhobo zensimbi. Siye sabona iindawo ezininzi kakhulu zisilela kwinkonzo-kungekhona kwi-chemistry ye-alloy embi, kodwa ukusuka kwi-passivation engahambelaniyo emva kokugaya i-multi-axis, okanye i-micro-cracking kwi-radii yangaphakathi ebukhali ngenxa yeendlela zesixhobo ezinobundlobongela.
At QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha 304 stainless hayi njengempahla yorhwebo, kodwa njengenkqubo esebenzayo. Yonke iqashiso ifumana ukuqinisekiswa kwe-spark spectrometry kwirisithi. Umatshini usebenzisa i-lathes yohlobo lwaseSwitzerland oluqinileyo kunye ne-5-axis mills ene-coolant-through-tool delivery-ibaluleke kakhulu ekukhutshweni kwe-chip kwiindawo ezinzulu ezifana ne-piston pump cylinder housings. Akukho ndlela zimfutshane. Akukho "kulunga ngokwaneleyo" umphezulu ogqityiweyo. Ukuba umzobo wakho ubiza iRa 0.4 µm kubuso obutywiniweyo, siyayilinganisa—asiyiqikelele—ngeeprofilometers ezibambekayo ezilinganiswe kwimigangatho ye-NIST.
Apho uMgangatho wama-304 udibana noBunjineli obuBalulekileyo
Umgangatho wama-304 usebenzela iitanki zodidi lokutya. Ayisebenzi ngokuzenzekelayo kwiindibano zepompo ye-cobalt-alloy ye-AMS 5387 esebenza kwi-450 ° C kunye ne-350 bar. Nangona kunjalo abathengi abaninzi basicela ukuba sisebenzise izixhobo ezingama-304 * ecaleni kwe-T800 superalloys kwizixhobo ekwabelwana ngazo. Yiyo loo nto indawo yethu inyanzelisa ukucandwa komhlaba okungqongqo: iiseli ze-CNC ezinikezelweyo, izikhululo zokusila ezahlukeneyo, kunye nezixhobo ezinemibala enemibala. Sifunde oku ngendlela enzima-ngethuba lophicotho-zincwadi lwe-2022, i-carbide enye elahlekileyo ifake intsalela yentsimbi kwisihlalo sevalve ye-304. Inxalenye iphumelele uvavanyo lwe-dimensional-kodwa aluphumelelanga uvavanyo lwesitshizi setyuwa kwiiyure ezingama-96. Isifundo sifakwe: ukucoceka kwe-metallurgical kuqala ngaphambi kokusikwa kokuqala.
Ukusetyenziswa kwethu rhoqo kwe-304 kubonisa iindawo zoxinzelelo lwehlabathi lokwenyani: imizimba yevalvu yoxinzelelo efuna ukugxila okuqinileyo (<0.015 mm) phakathi kwamazibuko okungena nawokuphuma; iziseko zempompo ezifuna ukucaca ngaphakathi kwe-0.05 mm ngaphezu kwe-600 mm; kunye ne-winch center shaft rollers eziphantsi kwe-cyclic torsional loads. Ezi ayizozinto zesitokhwe. Ziyi-GD&T-zinzima, zinonyamezelo lwezikhundla ezibhekiselele kwiimpawu zedatum ezenziwe ngoomatshini kwiseti enye-hayi ezintathu. Loo nto ifuna ucwangciso oludityanisiweyo lokwenziwa komatshini, hayi ulandelelwano lwezandla.
Yintoni "Ukwenziwa kweSiko okuThembekileyo" Okuhambisa ngokwenene
"Ithembekile" ithetha ukuba iprototype yakho ifika ngeentsuku ezili-18-hayi "kwiiveki ezi-3-4." Kuthetha ukuba ufumana iingxelo ze-CMM ezibonisa eyona nto iphikisana negama layo yonke imilinganiselo ebalulekileyo-kungekhona nje isitampu kuluhlu lokukhangela. Kuthetha ukuba xa injineli yakho ibhenela uphazamiseko olunokubakho kumzobo wendibano, sisebenzisa ukulinganisa okulinganayo kwedijithali *phambi* kokusika isinyithi—kwaye sicebisa uhlengahlengiso lweradiyasi eyi-0.03 mm egcina i-$12,000 ekusebenzeni kwakhona kwendawo.
Asikhupheli ngaphandle, unyango lobushushu, okanye uhlolo lokugqibela. Iziko lethu elithobela i-ISO liphatha utyalo-mali lwezindlu ezicekethekileyo ezingama-304, ukugalelwa kwesanti kwiziseko ezikhulu ukuya kuthi ga kwi-800 kg, kunye nokufakwa kwesisombululo se-post-cast kwiziko elilungelelanisiweyo eline-±3°C efanayo. Yonke into yokuphosa ifumana uhlolo lwe-RT okanye lwe-UT nge-ASTM E94/E165 nganye. Yonke inxalenye yomatshini ifumana ukuqinisekiswa okubonakalayo, okulinganayo, kunye nokusebenza-kubandakanywa nokuvavanywa koxinzelelo kwi-1.5 × uxinzelelo olusebenzayo kwimizimba ye-valve.
Oku kudityaniswa ngokuthe nkqo kusombulula eyona ndawo ibuhlungu esiyivayo kumaqela okuthenga: ukukhomba ngeminwe phakathi kwesiseko, ivenkile yomatshini, kunye ne-coater xa inxalenye isilela. Ngomlingani omnye onoxanduva, uhlalutyo lwengcambu luthatha iiyure-kungekhona iinyanga.
Ukukhetha Ngaphaya kwePhepha leBanga
Buza nawuphi na umthengi osele enamava: umahluko phakathi kweefektri ezimbini zentsimbi engenastainless ezingama-304 zihlala zilele kwiinkuni zazo ezingaphumeleliyo—hayi iincwadana zazo. Kwi-QINGDAO QIANGSENYUAN, uvimba wethu wolwazi wangaphakathi ongahambelaniyo ulandelela yonke itenxa: i-72% inxulumene nokugqwetheka okubambezelekayo okubangelwa ngabaqhubi kwiiflange ezibhityileyo; I-18% isuka kubushushu obunganeleyo phambi kokulungiswa kwe-welding ye-castings; I-10% ibandakanya ukutolikwa gwenxa kwe-GD&T callouts kwimizobo yelifa. Sabelana ngezi mbono-kungekhona njengentengiso, kodwa njengobunjineli obucacileyo.
Ukuba umyalelo wakho olandelayo uquka i-304 yentsimbi engenasici kwiinkqubo ze-hydraulic, i-oyile kunye ne-gas skids, okanye ii-winches zemoto yobunjineli, zifuna ngaphezu kwesicatshulwa. Cela: ii-certs ze-mill ezinamanani obushushu, iifayile zeprogram ye-CMM zokuhlolwa kwenqaku lokuqala, kunye nobungqina bokulinganisa komntu wesithathu ngonyaka kuzo zonke izixhobo ze-metrology. Emva koko thelekisa-kungekhona nje ixabiso, kodwa inkqubo yobunini.
A I-304 yefektri yensimbi engenasici elawula ukuziphatha kwe-alloy phantsi koxinzelelo, ilawula yonke into eguquguqukayo ukusuka kwi-melt ukuya kumlinganiselo, kwaye iphatha umzobo wakho njengekhontrakthi-kungekhona isiphakamiso-izuza ii-odolo eziphindayo. Hayi ngezithembiso. Ngokusetyenziswa okuqinisekisiweyo, okubhaliweyo, okuphinda-phindayo.
