Taonani, kutaya thovu. Ndi imodzi mwazinthu zomwe zimamveka bwino chifukwa cha kuthekera kwake - mawonekedwe apafupi, ma geometries ovuta, makina ocheperako. Koma yendani muzinthu khumi zodzinenera kuchita izo, ndipo mukhoza kuwona matanthauzidwe khumi osiyana a kupambana. Maganizo olakwika kwambiri? Kungoti ndi njira yoyeretsera kusiyana ndi kuponya mchenga kwachikhalidwe. Si. Ndi dongosolo lathunthu, ndipo ngati mawonekedwe anu a thovu, zokutira, kuphatikizika kwa mchenga, ndi zitseko sizikuyenda bwino, kuvina kosalimba, mukungowotcha polystyrene yodula kuti mupange zidutswa. Ndawona kuyesayesa kolephereka kuchokera kwa anthu omwe amachitira chithovu ngati chotayira m'malo motengera maziko enieni a njirayi.
Poyambira Kapena Kusweka: Chitsanzo Chokha
Zonse zimadalira mtundu wa thovu. Si mawonekedwe chabe; ndi chosungira malo osakhazikika. Tinaphunzira izi movutikira kale. Kupeza mikanda yotsika mtengo, yotsika kachulukidwe ya EPS kumatha kupulumutsa ndalama patsogolo, koma mizere yophatikizira mikanda imakhala malo olephera. Chithovucho chiyenera kukhala chowundana mokwanira kuti chigwire ntchito popanda kupotoza, koma gilamu iliyonse yowonjezera ndi mpweya wa gasi panthawi yothira, zomwe zimakhudza kutuluka kwachitsulo ndi kukhulupirika komaliza. Msonkhano wapatani-kumata zigawo zingapo za thovu-ndi wakupha wina mwakachetechete. Gwiritsani ntchito zomatira zolakwika, ndipo mwina sizimangirira olowa (zomwe zimapangitsa kuti zitsulo zilowe mu msoko, vuto loyipa lotchedwa veining) kapena zimasiya zotsalira za carbon zomwe zimapangitsa kuti ziphatikizidwe. Tinasinthira ku zomatira zapadera zosungunula zotentha kwambiri zomata kwambiri pambuyo poti matupi a ma valve akulephera kuphulika. Ndi minutiae iyi yomwe imalekanitsa mawonekedwe ndi mtundu wokonzekera kupanga.
Ndiye pali zokutira, slurry refractory. Izi si utoto; ndi chotchinga ndi permeability controller. Ndiwokhuthala kwambiri, ndipo mpweya wochokera ku thovu lomwe likutuluka nthunzi silingathe kuthawa mofulumira, zomwe zimapangitsa kuti chitsulocho chiyimire kapena kubwereranso. Wowonda kwambiri, ndipo mchengawo umathyoka, kupangitsa kuti pamwamba pake pakhale khwimbi. Kukhuthala kumafunika kuyang'anitsitsa nthawi zonse-kutentha ndi chinyezi m'sitolo kumakhudza kwambiri. Tikufuna zokutira zomwe zimauma mpaka pakhungu ngati ceramic, lolimba mokwanira kudzaza mchenga koma losasunthika losweka pansi kutsogolo kwachitsulo kuti mpweya utuluke. Ndi kukhazikika komwe mumamva, kwenikweni, ndi momwe kumadonthezera chala chanu.
Ndikukumbukira pulojekiti yopangira nyumba yopangira pampu yaying'ono, ntchito yovuta yamkati. Wofuna chithandizo ankachifuna muchitsulo cha ductile. Mayendedwe oyamba anali owopsa - kuchepa kwa porosity komwe kumalumikizidwa m'zigawo zokhuthala. The thovu, ndithudi, kutha ndipo sasiya kumatanthauza matenthedwe misa. Vuto linali loti geting yathu, yomwe idakopedwa kuchokera ku njira yoponyera mchenga, sinawerengere kutayika kowonjezera kwa kutentha kuchokera pakuwonongeka kwa thovu la endothermic. Tinayenera kukonzanso dongosolo lodyetserako chakudya kwathunthu, ndikuwonjezera zokwera zambiri m'malo omwe siachikhalidwe kuti zithandizire kuziziritsa kumeneku. Idawonjezeranso malo okhudza makina pambuyo pake, koma zinali zimenezo kapena zopanda pake. Chitsanzo ndi mankhwala, mpaka izo siziri.
Mchenga, Kugwedezeka, ndi Chinyengo cha Kuphweka
Mchenga wouma wosamangika. Zikumveka zosavuta. Koma kuphatikizika kwake mozungulira mawonekedwe osalimba, okutidwa ndipamene zilema zambiri zimabadwa. Gome logwedezeka ndiye mtima wake. Mufunika kugwedezeka kwanjira zambiri kuti mchenga uzitha kulowa m'bowo lililonse popanda kutulutsa kapena kupotoza. Mwaukali kwambiri, ndipo mutha kumeta makoma opyapyala kapena kupangitsa kuti zokutira ziphwanyike msanga. Kufatsa kwambiri, ndipo mumapeza madontho ofewa pamchenga, zomwe zimatsogolera kusuntha kwa khoma la nkhungu ndi kusalongosoka - zomwe timatcha kuphulika.
Timayendetsa mchenga wosakanikirana wa silika, ngakhale pamagiredi achitsulo chosapanga dzimbiri tasamukira ku zirconia chifukwa cha kukhazikika kwake kwamafuta. Chinsinsi chake ndi kusasinthasintha. Chinyezi chilichonse ndi mdani; imakhudzidwa ndi chitsulo chotentha ndi thovu lowola kupanga matumba a nthunzi, kuchititsa mapini. Timawumitsa mchenga mu chowumitsira chozungulira ngati pali chinyezi. Ndi sitepe yowonjezera, koma ndi yotsika mtengo kusiyana ndi kutentha kwathunthu pambuyo pake kuyesa ndikusindikiza porosity yomwe simungathe kuwona pamwamba.
Kuthira komweko kumatsutsana ndi nyengo koma kumakhala kovuta. Mukuthira zitsulo pa zomwe zili mafuta. Mtengo wake ndi wovuta kwambiri. Pang'onopang'ono, ndipo chithovu chimawonongeka kutsogolo kwachitsulo kutsogolo, zomwe zimapangitsa kuti chibowo chigwere kapena mchenga ulowemo. Mofulumira kwambiri, ndipo kutuluka kwa gasi kumapangitsa kuti zokutira ziwonongeke, zomwe zimayambitsa chipwirikiti ndi slag inclusions. Mumayang'ana polowera utsi, mtundu wake ndi kutuluka kwake kumakuuzani ngati kupsako kuli koyera. Utsi wakuda, wamafuta umatanthauza kuyaka kosakwanira, vuto. Muli wokhazikika, wotuwa-woyera ndi zomwe mukufuna. Ndi njira yomvera kwambiri.
Pomwe Ikukwanira ndi Pomwe Siikuyenera
Kutaya thovu kuwala kwa mabanja ena a magawo. Mipiringidzo ya injini, mitu ya masilinda, mitundu yosiyanasiyana—maonekedwe ocholoŵana okhala ndi njira zamkati zimene zimafuna machubu a mchenga ovuta ndiponso okwera mtengo. Kuchotsa ma core assembly ndi ma core prints ndikupulumutsa kwakukulu pantchito ndikuwongolera kusasinthika kwa mawonekedwe. Kwa kampani ngati Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ndi zaka makumi ambiri mu chipolopolo ndi ndalama zoponyera ndalama, kuwonjezera thovu lotayika ku mbiriyo kunali pafupi kupereka ndondomeko yoyenera ya geometry yoyenera. Nthawi zina, gawo lomwe timatchula likhoza kupangidwa ndi nkhungu ya chipolopolo kapena thovu lotayika. The breakpoint nthawi zambiri mkati zovuta ndi voliyumu. Pakuthamanga kwa zidutswa 500 za ma hydraulic valve body okhala ndi malo ophatikizika amafuta, chithovu chotayika chimapambana. Kwa zidutswa 50 za nozzle yotentha kwambiri mu cobalt alloy? Kubwerera ku Investment casting.
Kuchepetsa kwazinthu ndi zenizeni. Aluminiyamu ndi chitsulo chotuwira ndizomwe zimakhululukira kwambiri. Chitsulo chachitsulo chimafuna kuwongolera mwamphamvu kwa magnesiamu (kuwonongeka kwa thovu kumatha kusokoneza nodularization). Chitsulo ndi chosapanga dzimbiri ndi zotheka, koma kutenthedwa kwa kutentha pa zokutira ndikokwera kwambiri, ndipo chojambula cha carbon pamwamba pa thovu ndichodetsa nkhawa kwambiri. Tachita bwino mabulaketi 304 osapanga dzimbiri, koma zimafunikira zokutira zokhala ndi kukana kwambiri komanso kutsanulira kolondola kwambiri, mwachangu. Sikuti amapita kwa zitsulo zapamwamba aloyi pano; kuponya ndalama kudakali mfumu chifukwa cha izi, chifukwa cha ukatswiri wa QSY wokhala ndi faifi tambala ndi ma aloyi opangidwa ndi cobalt. Mumasewera mphamvu ya ndondomekoyi.
Post-Process: The Reality Check
Shakeout ndiyosavuta—ingotembenuzani bokosilo. Koma kuyang'ana koyamba pakuyimba ndikuwunika zenizeni. Kumwamba kumakhala ndi mawonekedwe, ovutirapo pang'ono, mawonekedwe a peel lalanje kuchokera pamawonekedwe okutira. Ndi yabwino kuposa kuponya mchenga koma osati yosalala ngati ndalama. Pafupifupi nthawi zonse mudzawona filimu yopepuka, yobiriwira m'mphepete; nthawi zambiri amaphulika m'chipinda choyeretsera. Zowonongeka ndizosiyana. Mchenga wophwanyika umawoneka ngati wokhotakhota mwadzidzidzi, woipitsitsa. Kulowa kwachitsulo kumawoneka ngati zipsepse zolimba, zachitsulo motsatira msoko. Gasi porosity imafalikira kwambiri, nthawi zambiri pansi pa nthaka.
Machining ndi pomwe kukhazikika kwa dimensional kumalipira. Popanda masinthidwe oyambira, mawonekedwe a datum ndi odalirika. Koma muyenera kudziwa malo a spongy. Nthawi zina, mamilimita awiri kapena awiri pansi pa nthaka ngati-kuponyedwa, pangakhale wosanjikiza wa yaying'ono porosity kuchokera chithovu kuvunda mpweya. Sikuti nthawi zonse imakhala ndi chilema, koma ngati muli ndi nkhope yosindikiza yovuta, mumatchula makina odulidwa osachepera 2mm kuti mulowe pansi pake. Tidaphunzira izi pambuyo pa gulu la ma compressor housings atayesa kukakamiza koyambirira, koma adalephera m'munda atavala pang'ono. Wopalamulayo anali kabowo kakang'ono pamalo osindikizira omwe ankavala otsegula. Tsopano ndi cholembera chokhazikika pamawonekedwe ovuta.
Malingaliro Omaliza: Chida, Osati Chozizwitsa
Choncho, ndi kutaya thovu m'tsogolo? Kwa zigawo zina, mwamtheradi. Ndi njira yabwino yothetsera mavuto enaake. Koma ndi mwambo wovuta, wokhudzidwa ndi ndondomeko. Imapindulitsa kusamala ndikulanga kuyerekezera. Sichinthu chomwe mumangowonjezera pa maziko. Pamafunika selo lodzipatulira, kuyambira kuumba patani mpaka kugwira mchenga. Kwa othandizira ophatikizika ngati QSY (mutha kuwona kuthekera kwawo pa https://www.tsingtaocnc.com), ndi chida china chanzeru. Zimawalola kuwongolera kasitomala - kunena, wina yemwe akufunika chitsulo chokhazikika chokhala ndi mayendedwe amkati - kunjira yabwino kwambiri. Nthawi zina chithovu chotayika, nthawi zina ndi njira yawo yopangira nkhungu. Phindu ndi kudziwa kusiyana, mu shopu pansi nzeru zimene ndondomeko iliyonse amamva ngati ikuyenda bwino, ndipo chofunika kwambiri, pamene izo zatsala pang'ono kulakwika. Ndi chinthu chomwe palibe bukhu lomwe lingajambule.
