Mukamva 'kuponyedwa kwa alloy investment', chithunzi chomwe chilipo nthawi zambiri chimakhala cham'mlengalenga, chowoneka ngati ukonde. Ndizowona, koma ndi kabuku kakang'ono kokha ka glossy. Chowonadi pa maziko a maziko ndi owopsa, ochulukirapo. Lingaliro lolakwika lodziwika bwino ndikuti ndi njira imodzi yokhayokha pagawo lililonse lovuta. Zowonadi, kutheka kwake kumadalira kusanthula kwankhanza kwa phindu la geometry motsutsana ndi kuchuluka kwake. Kodi ndizoyenera chipolopolo cha ceramic, mawonekedwe a sera, nthawi yayitali yotsogolera? Kwa bulaketi yosavuta, pafupifupi konse. Kwa impeller yokhala ndi ma vanes amkati, nthawi zambiri ndiyo njira yokhayo. Luso lenileni sikungopanga sewero; ndikudziwa pamene osagwiritsa ntchito kuponya ndalama konse.
The Core Dance: Sera, Shell, ndi Metal
Njirayi ikuwoneka ngati mzere m'mabuku ophunzirira: sera, kusonkhana, kumanga zipolopolo, sera, kupsa mtima, kutsanulira. Pochita, sitepe iliyonse ndi kukambirana. Tengani sera. Kapangidwe kake sikokwanira; Sera ya gawo lachitsulo chosapanga dzimbiri lokhala ndi mipanda yopyapyala imachita mosiyana ndi imodzi ya aloyi ya cobalt yokhuthala. Mitengo ya shrinkage imasiyanasiyana, ndipo ngati ndondomeko yanu ya sera siyikuwerengera kuchulukitsitsa kwachitsulo molondola, mukuchotsa malire a phindu pambuyo pake. Ndawonapo mapulojekiti pomwe zoyambira zojambulira sera zidakopera kuchokera ku ntchito 'yofanana', ndikungotulutsa njira zopotoka zomwe zidasokoneza kukhulupirika kwa chipolopolo chonse. Ndi sitepe yoyambira yomwe imanyalanyazidwa.
Kenako pamabwera chipolopolo cha ceramic. Chiwerengero cha dip-ndi-stucco cycle sichitha; ndi ntchito ya aloyi kutsanulira kutentha ndi gawo misa. Aloyi ya nickel yapamwamba yotsanuliridwa pa 1500 ° C imafunikira chipolopolo cholimba kuti ipewe kugwedezeka kwa kutentha ndi kulowa kwachitsulo. Zosanjikiza zochepa kwambiri, ndipo mutha kukhala pachiwopsezo cha kutha kapena kuponyedwa 'kophwanyidwa' chifukwa chosweka chipolopolo. Zochuluka kwambiri, ndipo mumatchera mpweya mukamawotcha, zomwe zimatsogolera ku thovu la zipolopolo zomwe zimakhala zolakwika pakuponya komaliza. Ndi luso logwira ntchito - kuweruza makulidwe a chipolopolo potengera kulemera kwake kwa mtundu wobiriwira komanso kumveka kwake pogogoda.
Gawo lotopetsa ndilofunika kwambiri, koma nthawi zambiri limatengedwa ngati njira yosavuta ya uvuni. Sikungosungunula sera; ndi za kutembenuza chigobacho kukhala choumba cholimba, chotha kulowa mkati. Mitengo ya ramp ndi yofunika. Mofulumira kwambiri, ndipo sera yokulirakulira imatha kung'amba chipolopolo. Kuchedwa kwambiri, ndipo mumasiya zotsalira za kaboni zomwe zingayambitse kuwonongeka kwa pamwamba pa kuponyera. Kwa ma alloys omwe amakhudzidwa ndi kujambula kwa kaboni, monga zitsulo zosapanga dzimbiri ziwiri, izi ndi tsoka. Mlengalenga wa ng'anjo umafunikanso kuyang'anitsitsa.
Zosankha Zakuthupi: Si Chitsulo Chopanda Chopanda Chabe
Makasitomala nthawi zambiri amatchula chitsulo chosapanga dzimbiri ngati kuti ndi chinthu chimodzi. Makhalidwe oponyera 304L motsutsana ndi 316L, osasiya kalasi yowumitsa mvula ngati 17-4PH, ndi yosiyana kwambiri. Kutentha kwamadzi, chizolowezi chong'ambika ndi kutentha, zofunikira zodyetsa - zonsezi zimasintha. Apa ndipamene kupeza kwanthawi yayitali kumapindulitsa. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., okhala ndi mbiri yawo ya zaka 30, akanamanga laibulale yakuya, yothandiza ya makhalidwe ameneŵa. Mutha kuwerenga zidziwitso, koma podziwa kuti aloyi wopangidwa ndi faifi tambala, iti Inconel 718, ali ndi chizolowezi chopanga mawanga ngati kutentha kothira sikukuyendetsedwa mwamphamvu, kumabwera chifukwa chotaya magulu angapo kuti muphunzire movutikira.
Ma alloys apadera, monga cobalt kapena faifi tambala, amayambitsa wosanjikiza wina. Nthawi zambiri amasankhidwa kuti asachite dzimbiri kapena kutentha kwambiri, koma amatha kukhala zilombo zotayirira. Amakhala ndi malo osungunuka kwambiri, omwe amagogomezera dongosolo la zipolopolo, ndipo magawo awo olimba amatha kukhala ovuta. Kukwera ndi kukwera kwa zinthu izi sikoyenera. Mufunika ma feeders okulirapo kuti muthane ndi kuchepa kwakukulu, komwe kumakhudza zokolola. Kuwerengera kwachuma kumasintha kwambiri. Mtengo wake suli mu aloyi wokwera mtengo wokha; lili muvyuma vyakusolola nge kulikata nakukunguluka.
Apa ndipamene makina ophatikizika amakhala osakambitsirana. Choyambitsa chomwe chimangoponyera ndikusiya ndalama ndi kuwongolera khalidwe patebulo. Kuponya ndi njira yofanana ndi ukonde, koma 'pafupi' ndi mawu ogwiritsira ntchito. Nkhope zovuta za datum, mabowo opangidwa ndi ulusi, ma diameter olekerera amafunikira makina. Kukhala ndi luso la CNC m'nyumba, monga QSY imachitira, kumatanthauza kuti gawolo likhoza kupangidwa ndi ndondomeko yonse m'maganizo. Mutha kusiya zida zaukadaulo m'malo ena mukudziwa kuti mudzazipanga pambuyo pake, zomwe zimakhala zogwira mtima kwambiri kuposa kuyesa kulolerana ndi ma micron paliponse, zomwe sizingatheke.
Zovuta Zenizeni Zapadziko Lonse ndi Zosokoneza
Njira zamabuku zimatengera mikhalidwe yabwino. Zowona sizimatero. Mutu wobwerezabwereza ndikusintha kwapakati. Ngakhale ndi chipolopolo chopangidwa mwangwiro, panthawi yothira, mphamvu yachitsulo yosungunuka imatha kukweza kapena kusuntha zitsulo zamkati za ceramic. Ndinkagwira ntchito panyumba ya valve pomwe chigawo chamkati chimasuntha ndi 1.5mm chabe, ndikupangitsa gulu lonse kukhala lopanda ntchito. Kukonza sikunali mu kuthira; zinali mu kukonzanso pachimake zipsera ndi zogwiriziza mu sera chitsanzo siteji. Idawonjezera milungu iwiri pamndandanda wanthawi ya prototyping.
Zoyembekeza zomaliza zapamwamba zimafunikiranso kuyang'aniridwa. Kuyika ndalama kumapereka mapeto abwino, koma 'monga-cast' sikufanana ndi 'makina'. Pazigawo zomwe zimayang'anizana ndi kutuluka kwamadzimadzi, monga zida zapampu, kuuma kwina kwina kungakhale kovomerezeka. Kwa implant yachipatala, sichoncho. Nthawi zambiri, mumalinganiza mtengo womaliza bwino kwambiri (kudzera m'zipatso zokongoletsedwa bwino za ceramic, malaya ochulukirapo) motsutsana ndi kungotchula makina opepuka kapena kuphulitsa pambuyo poponya. Zotsirizirazi nthawi zambiri zimakhala zodalirika komanso zotsika mtengo.
Nthawi yotsogolera ndi wina wakupha mwakachetechete. Anthu amawona kutsika kwachangu ndikuganiza kuti ndikofulumira. Amayiwala masabata a 2-3 opangira zida, sabata yomanga zipolopolo ndi kuyanika, masiku otopa. Ndi ndondomeko yoyesedwa mu masabata, osati masiku. Pempho lililonse lothamangira nthawi zambiri limatanthauza kunyalanyaza nthawi yowumitsa zipolopolo, yomwe ndi tikiti yachindunji yakulephera kwa nkhungu. Palibe bungwe lodziwika bwino lomwe liyenera kuvomereza izi.
Ubwino Wophatikizira: Kuchokera Kuponya mpaka Gawo Lomaliza
Apa ndipamene chitsanzo cha malo ogulitsa makina ophatikizana ndi makina, monga omwe amatchulidwa ndi mautumiki a QSY, amasonyeza mtengo wake weniweni. Pamene kuponyera ndi makina ali pansi pa denga limodzi, kuzungulira kwa mayankho kumakhala kolimba. Katswiri wamakina amapeza malo olimba osalekeza kapena porosity yapansi panthaka m'dera linalake la kuponyera. Chidziwitso chimenecho chimabwereranso kwa injiniya woyambira. Kodi inali nkhani yozizirira m'deralo? Chokwera chosakwanira? Iwo akhoza kusintha gating kamangidwe kwa kuthamanga lotsatira. Kuthetsa vutoli kotsekedwa sikutheka pamene kuponyedwa kumatumizidwa ku malo ogulitsa makina omwe amangolemba madandaulo pa lipoti labwino.
Taganizirani zachitsulo chosapanga dzimbiri. Wojambula, ali ndi nkhope za flange ndi mabowo a bawuti. Pamakonzedwe ophatikizika, pulogalamu ya CNC imatha kupangidwa ndi shrinkage factor yomwe yaphikidwa kale. Kulumikizana kumeneku kumachepetsa nthawi yokhazikitsira ndikuwonetsetsa kuti envulopu yopangira makina ikulemekeza miyeso yeniyeni ya oponyawo, osati mtundu wake wongoyerekeza wa CAD. Imachepetsa zowonongeka ndikufulumizitsa kutumiza.
Chidziwitso chakuthupi chimafikiranso pano. Kupanga aloyi ya cobalt ndi yosiyana ndi kupanga kapamwamba kofananako. Ma microstructure, kuuma, ndi kuthekera kwa ma abrasive inclusions amasiyana. Gulu lophatikizika limadziwa momwe angasankhire zida zoyenera, kuthamanga, ndi kudyetsa kuchokera pazochitikira, kupewa zida zosweka ndi kumaliza kosawoneka bwino pagawo lomaliza, lamtengo wapatali.
Malingaliro Omaliza: Luso la Pragmatic
Ndiye, chotengera ndi chiyani? Kutulutsa kwa Alloy Investment ndi njira yamphamvu, nthawi zina yofunikira, yopangira. Koma kupambana kwake kumakwiriridwa mwatsatanetsatane zomwe sizili mu malonda ogulitsa: musanganizo wa sera, chinyezi cha chipinda cha zipolopolo, piritsi lamoto, ndi chidziwitso chakuya cha momwe aloyi inayake imadzaza ndi kuchepa. Simatsenga; ndi mndandanda wa zolamuliridwa, zosokoneza, zakuthupi.
Zomwe zikuchitika, moyenerera, zikupita kwa othandizira ophatikizika. Zimangomveka. Zovuta za kupanga kuponyedwa kwapamwamba kwambiri zimagwirizanitsidwa ndi masitepe omwe amabwera patsogolo ndi pambuyo pake kuti kupatukana kumayambitsa chiopsezo ndi mtengo. Mukayang'ana luso la ogulitsa, mndandanda wazinthu monga chitsulo chosungunuka, chitsulo, chosapanga dzimbiri, ndi ma aloyi apadera ndi chiyambi. Koma funso lenileni ndilakuti: ndi kangati adathira izi, kuzipanga izi, ndikuthetsa mavuto omwe amangowoneka mukayesa kupanga zonse ziwiri kuti mupange gawo logwira ntchito? Ndicho chochitikira chofunika.
Pamapeto pake, ndi luso la pragmatic. Sikuti mukungogula zowonera; mukugula zomwe zasonkhanitsidwa, zomwe nthawi zambiri zimapambana, kuweruza kwa gulu lomwe limadziwa kuyendetsa ulendo wonse kuchokera ku 3D model kupita ku gawo lomaliza, lodalirika m'manja mwanu. Chiweruzo chimenecho ndicho chinthu chenicheni.
