Xa iinjineli zichaza iinxalenye zentsimbi ephoswe ngentsimbi kwiimpompo zehydraulic okanye iifestile zemoto yobunjineli, azifuni nje “igiya.” Bafuna uzinzo lwe-dimensional phantsi kwe-350-bar yoxinzelelo. Ukunyaniseka kwe-Microstructure emva kwe-10,000 imijikelezo yomthwalo we-torsional. Isiphelo somphezulu esixhathisa i-slurry e-abrasive ngaphandle kwe-micro-pitting. Yiyo loo nto ukukhangela kwinyani umzi-mveliso wezixhobo zentsimbi-hayi i-general foundry okanye i-contract machinist-ayinakuxoxisana.
EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye ngoomatshini phezu 17,000 cast izixhobo zentsimbi izindlu iindibano impompo piston ukususela 2019. Siye sabona into engasileliyo: iigiya nge graphite nodule iqhuqhuva kufutshane neengcambu izinyo; iindawo eziphathwa ngobushushu ngokukhawuleza kakhulu kwaye ziqhekekile ngexesha lokusila kokugqibela; Ukuphosa okugalelwe ngamazinga okupholisa angahambelaniyo ajike emva kokuguqulwa kwe-CNC. Amava okwenene—kungekhona iincwadana ezinemifanekiso—abumba indlela esihlangabezana ngayo nazo zonke iiodolo.
Amandla ethu aqala ngokudibanisa ngokuthe nkqo. Uninzi lwababoneleli abakhuphela ngaphandle, ukwenza oomatshini, okanye ukugqiba. Silawula zontathu kwiziko elinye elihambelana ne-ISO eQingdao. Oko kuthetha ukuba akukho handoffs phakathi kwabathengisi-kwaye akukho zithuba ekulandeleleni. Xa umthengi ethumela imizobo ye-GD & T yomphathi wegiya esetyenziswa kwi-oyile engaselunxwemeni kunye neempompo zodaka zerhasi, iqela lethu liqinisekisa umgangatho wezinto eziphathekayo (i-ASTM A48 Class 30 vs. Class 40), ilinganisa ukuqiniswa kokuqina kwizibungu zesanti, iinkqubo ze-multi-axis CNC iindlela zokubamba i-± 0.015 mm kwi-runout-face-fiess hard-face-fiess final-fixing. (220–260 HB) nabavavanyi beRockwell abalinganisiweyo. Inyathelo ngalinye libophelela kwinani lebhetshi efanayo, ilog efanayo yokuphatha ubushushu, ingxelo efanayo yeCMM.
Sisebenza ngokukhethekileyo kwizicelo apho ukusilela kungeyondlela yokukhetha. Qwalasela iinxalenye zempompo ye-cobalt-alloy efana neegiya ze-AMS 5387 okanye i-T800-based based shaft rollers kwiiwintshi zebhodi. Ezi ayingomalungu angekho kwishelufu. Bafuna ulawulo oluchanekileyo lwe-graphite morphology kwisiseko sokugalela kwentsimbi, elandelwa kukusilwa okuqinileyo kweeprofayili ezingabandakanywayo kunye nemiphezulu yokuthwala eqinileyo. Sisebenzisa ukuphosa kwesanti eluhlaza ukuqina kolwakhiwo, emva koko sigqibe amazinyo esixhobo sokusila koomatshini be-5-axis abane-Renishaw probing-akukho kulungelelaniswa kwezandla. Abathengi baseMntla Melika naseJamani bayaqinisekisa: isivuno sethu sokuqala kula macandelo siphakathi kwe-94.7%, kungekhona isiqhelo soshishino lwama-72-78%.
Abanye banokuphikisa ukuba i-US yasekhaya okanye i-EU Foundries inikeza amaxesha okukhokela ngokukhawuleza. Kodwa xa i-OEM yaseYurophu idinga imizimba ye-valve ye-42 yoxinzelelo kwi-QT450-10 i-ductile iron-kunye ne-12 ye-bores ebalulekileyo efuna ukunyamezela kwe-± 0.01 mm-sahambisa ngeentsuku ze-28. Njani? Ngenxa yokuba inkqubo yethu ye-hybrid yokwenziwa komatshini kuphelisa ukulungiswa kwakhona. Siphosa iimilo ezikufutshane ne-net kunye neendawo ezidibeneyo, emva koko ngomatshini yonke imiphezulu esebenzayo kwiseti enye. Akukho misebenzi yesibini. Akukho zimpazamo zesixokelelwano sokuguqulela. Ukuchaneka okuphindaphindiweyo, okubhalwe kuyo yonke indawo yokukhangela: ii-certs eziphathekayo ezingenayo, i-CMM kwi-process iskena zonke iziqwenga ezi-5, uvavanyo lokugqibela olusebenzayo kunye ne-hydraulic pressure cycling ukuya kwi-400 bar.
- Ukulandeleka kwezinto: Iirekhodi ezipheleleyo zomgangatho welotsi-ukusuka kuhlalutyo lwentsimbi ekrwada yokunyibilika ukuya kuburhabaxa bokugqibela bomphezulu weRa 0.8 µm
- Akukho "standard" compromises: Sisebenza ngoomatshini bomlinganiselo ongeyomgangatho wegiya, ii-engile ze-helix ukuya kuthi ga kwi-32 °, kunye nobubanzi bobuso obungaphezulu kwe-180 mm ngaphandle kokuncama ipateni yoqhagamshelwano lwamazinyo.
- Ukuqinisekiswa kwehlabathi lokwenyani: Zonke iinqanawa zezixhobo zezindlu ezinengxelo yohlolo esayiniweyo ebonisa amaxabiso alinganisiweyo okwenene-hayi nje ukudlula/izitampu zokusilela
Ukuba uvavanya a umzi-mveliso wezixhobo zentsimbi, buza imibuzo emithathu: Ngaba banokubamba i-0.02 mm iyonke yesalathisi sokufunda kwisixhobo sokubaleka esingenanto *emva* konyango lobushushu? Ngaba benza isampulu ye-metallographic kuyo yonke iqashiso le-10 lokuphosa-okanye kuphela ngexesha lophicotho? Kwaye ngaba iinjineli zabo zihlaba umkhosi kwiingxabano ze-GD&T *phambi kokusika isinyithi, hayi emva kokuba kwenziwe i-scrap? Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, ezo ayizizo iitshekhi zethiyori. Ngamanyathelo okuhamba komsebenzi wemihla ngemihla-eyakhelwe kwishedyuli ye-ERP, efakwe kuluhlu lokukhangela abasebenzi, kwaye iqinisekiswe ngabaphicothi-zincwadi beqela lesithathu kabini ngonyaka.
Ikamva lelabavelisi abaphatha ukuphosa kunye nomatshini njengezifundo ezixhomekeke omnye komnye-hayi iinkonzo ezilandelelanayo. Sandisa i-R&D kwiinkqubo ezixubeneyo: amazinyo egiya anelaser-clad kwi-substrates yentsimbi, utyalo-mali olusondeleyo lwabathwali begiya ezinodonga olucekethekileyo, kunye noyilo oluncediswa yi-AI ukuze kuncitshiswe i-porosity kwiindawo ezinoxinzelelo oluphezulu. Kodwa ixabiso lanamhlanje lihlala lingatshintshi: ukuveliswa kwesiko elithembekileyo kumacandelo ahambisa imithwalo enzima, itywina uxinzelelo oluphezulu, kwaye isebenze apho ixesha lenkonzo lifikelela kwiinyanga ezili-18. Akunjalo ngenxa yokuba kulula-kodwa ngenxa yokuba kufuneka ilungile.
