Pakatikati pa Njirayi: Zonse Ndi Za Shell
Zonse zimadalira chipolopolo cha ceramic. Ambiri obwera kumene pofufuza zitsulo amaganiza kuti chitsulo ndi nyenyezi, koma chipolopolo ndi siteji, wotsogolera, ndi wopanga zovala zonse pamodzi. Chigoba chofooka chimatanthauza kutha kapena chipsepse; chigoba chosagwirizana chimatsogolera ku makulidwe a khoma losagwirizana. Timathera masiku, nthawi zina masabata, pakupanga slurry ndi ndondomeko ya stuccoing. Kwa choyikapo chopopera chofunikira mu 316L, mwachitsanzo, titha kugwiritsa ntchito chojambulira chophatikizika cha silika kuti chimalizike bwino, koma sinthani ku zircon pamalaya osunga zosunga zobwezeretsera chifukwa chokana kwambiri. Ndi zisankho izi, zomwe nthawi zambiri siziwoneka kumapeto, zomwe zimatsimikizira kupambana kapena bwalo lodzaza ndi zidutswa.
Kuwongolera kutentha panthawi ya dewaxing ndi wakupha wina mwakachetechete. Mofulumira kwambiri, ndipo chipolopolocho chimang'amba kuchokera ku sera yomwe ikukula. Mochedwa kwambiri, ndipo mumasiya zotsalira zomwe zimasandulika kukhala carbon inclusions panthawi yothira. Ndikukumbukira gulu lina la zokometsera za m'madzi momwe tinali ndi kutentha kwa uvuni pang'ono - madigiri 15 Celsius kuposa momwe timasinthira. Chotsatira sichinali kulephera nthawi yomweyo; zipolopolo zimawoneka bwino. Koma pakuthira, ming'alu yaying'onoyo idalola kulowa kwachitsulo, ndikupanga malo owoneka bwino, osavomerezeka amkati omwe sanawonekere mpaka makina oyamba adutsa. Ili linali phunziro lofunika kwambiri pakudalira, koma kutsimikizira, pagawo lililonse.
Ndiyeno pali kupsya mtima. Sikuti amangosungunula sera. Ndi za kutembenuza zinthu zilizonse zotsalira kukhala phulusa zomwe zitha kuchotsedwa, osasiya mpweya woipa kuti uipitse chitsulo chosapanga dzimbiri. Kwa magiredi awiri ngati 2205, izi ndizofunikira kwambiri chifukwa zomwe zili ndi mpweya zimakhudza mwachindunji kukana dzimbiri. Inu simungakhoze kungowotcha izo motentha; mumatsatira mkombero wolondola wa kutentha. Apa ndipamene zaka zambiri zakuchita, monga mtundu womwe umamangidwa pakampani monga Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., kusintha. Mumakulitsa kumverera kwa izo. Kuganizira kwawo kwa nthawi yayitali chipolopolo nkhungu kuponyera ndi kuponya ndalama limapereka chidziwitso chakuya, chogwira ntchito cha masitepe osasangalatsa koma ofunikira.
Zofunika Si Zolemba Zapadera
Kutchula chitsulo chosapanga dzimbiri kuli ngati kunena kuti galimoto ndi yopanda tanthauzo popanda mtundu wake. 304, 316, 17-4PH, 2205-onse amachita mosiyanasiyana mu crucible ndi nkhungu. 304 ndi yokhululuka, koma kuchepa kwake ndikofunika. 17-4PH, kalasi yowumitsa mvula, ndi yabwino kwambiri pakulimbitsa thupi, koma ndizovuta kwambiri kung'amba kotentha ngati khomo lanu ndi njira yokwera sinapangidwe kuti igwirizane ndi mawonekedwe ake olimba. Simungagwiritse ntchito malingaliro odyetsa omwewo pa aloyi iliyonse.
Tinaphunzira izi movutikira ndi chitsanzo cha bulaketi yazamlengalenga. Kusindikiza kumayitanitsa 17-4PH mu chikhalidwe cha H900. Timachiponyera, timachipanga, timachithira kutentha. Iwo anadutsa dimensional macheke koma analephera akupanga anayendera. Misozi yaing'ono, yotentha mkati. Nkhani yake? Zokwera zathu, zabwino kwa 316, sizinapereke kulimba kokwanira kwa aloyiyi. Tinayenera kubwereranso, kutsanzira kulimbanso ndi zinthu zenizeni, ndikukonzanso dongosolo lonse la gating. Inawonjezera milungu itatu ku polojekitiyi.

Kumene Kuponyera Kutha ndi Machining Amayambira
Uwu ndiye mwayi waukulu, ndipo ndipamene ma projekiti ambiri amapunthwa. Ayi zitsulo zosapanga dzimbiri mwatsatanetsatane kuponyera ndi mawonekedwe a ukonde kwa ziwalo zogwirira ntchito. Nthawi zonse pamakhala nkhope za datum zoti zisinthidwe, ulusi wokhomedwa, kapena malo osindikizira kuti amalize. Chofunika kwambiri ndi strategic stock allowance. Ikani katundu wambiri paliponse kuti mukhale otetezeka, ndipo mukuwononga ndalama pazitsulo zowonjezera ndi nthawi yokonza makina. Ikani pang'onopang'ono, ndipo mumakhala pachiwopsezo chothyola khungu, ndikuwonetsetsa porosity yomwe ingakhalepo.
Choyenera ndikuthandizana ndi gulu lopanga makina kuchokera pagawo lopanga. Nthawi zonse timakhala tikuyesetsa kuzindikira zolumikizana mwachangu - mwachitsanzo, nkhope ya flange yomwe imalumikizana ndi chigawo china kapena chibowo cholumikizira. Maderawa amapeza ndalama zolipirira katundu, nthawi zambiri 0.5-1mm. Malo osakhala ofunikira amatha kusiyidwa ngati akuponyedwa, omwe, ngati ndondomeko yanu ya chipolopolo ili yabwino, ikhoza kukhala yoyera kwambiri. Njira yophatikizikayi ndi yomwe imalekanitsa wopereka magawo ndi wopereka mayankho. Zikuwonekeratu kuchokera ku zopereka za QSY zophatikiza CNC makina kuti ntchito pa mfundo imeneyi, kulamulira ndondomeko kuchokera nkhungu yomalizidwa machined gawo, amene amathetsa wosanjikiza waukulu wa zolakwa kulankhulana ndi khalidwe kuloza chala.
Ndikukumbukira pulojekiti yamagulu a valve pomwe mapangidwe oyambira anali ndi yunifolomu 3mm stock. Wopanga makinawo adakhala 80% ya nthawi yake akuchotsa zitsulo m'malo osagwira ntchito. Pakukonzanso zoponyamo kuti tiwonjezere zinthu zokhazo zomwe zimafunikira pakukonza ma datum ndi zisindikizo zofunika kwambiri, tidachepetsa kulemera kwake ndi 18% ndikudula nthawi yopanga makina pakati. Ndalama zomwe anasunga zinali zochititsa chidwi kwambiri. Kodi tikuphunzirapo chiyani? Kuponyera mwatsatanetsatane kumakhudzanso kuchotsera mwanzeru kunsi kwa mtsinje monga momwe zimakhalira ndikuwonjezera mowongolera muzoyambira.
Zowona Zakulekerera ndi Kumaliza
Miyezo yamakampani ngati ISO 8062 imakupatsani mwayi wololera, koma ndizoyambira, osati zotsimikizira. Kulekerera kwa CT5 pamlingo wa 50mm ndi ± 0.35mm. Koma kodi mungasunge izi pagulu lonse, pachinthu chilichonse? Zokayikitsa. Zomwe zili pamzere wotsatsira zitha kukhala zosiyanasiyana. Makoma owonda ndi ovuta kuwongolera kuposa okhuthala. Chigamulo chenicheni cha akatswiri ndikudziwa kuti ndi zololera ziti zomwe zili zamalonda ( geometry wamba) ndi zomwe zili zofunika (zoyenera, ntchito). Mukukambirana ndikuyang'ana ndondomeko yanu pazovuta kwambiri.
Kumaliza pamwamba ndi malo ena okonzeka kusamvetsetsana. Wamba kuponya ndalama akhoza kukwaniritsa Ra wa 3.2 kuti 6.3 micrometers monga-cast. Ndizo zabwino, koma sizinapukutidwe. Ngati mukufuna Ra 0.8 kwa chisindikizo champhamvu, mudzafunika makina kapena kupukuta. Njira yoponyera imatha kukuyandikirani, koma siyingachite zozizwitsa. Makasitomala amandifunsa magalasi omalizidwa molunjika kuchokera ku nkhungu. Izo sizimagwira ntchito mwanjira imeneyo. Muyenera kufotokoza kukula kwa njere za ceramic, mawonekedwe apakati pa chovala choyamba cha slurry ndi chitsulo-ndi malire.
Miyezo yoyendera zowoneka imafunikiranso kumveka bwino. Kodi kupanda ungwiro kwakung'ono kovomerezeka ndi kotani? Kuphatikizikako pang'ono pamalo osapanikizika, osadzikongoletsa kumatha kukhala kovomerezeka pamiyezo ya ASTM, koma kasitomala yemwe amagwiritsidwa ntchito popanga zida zopanga kapena makina amatha kukana. Kukhazikitsa zoyembekeza izi patsogolo, ndi zitsanzo zakuthupi ngati kuli kotheka, ndikofunikira. Ndi bwino kusonyeza chitsanzo chokhala ndi mawonekedwe apamwamba kusiyana ndi kukangana zidutswa 500 zitapangidwa.
Zolephera Ndi Aphunzitsi Enieni
Inu simumaphunzira kulondola kuchokera ku dongosolo langwiro; mumaphunzira kuchokera m'mabini akale. Nthawi ina tinali ndi vuto lobwerezabwereza ndi micro-porosity pakatikati pa gudumu laling'ono la turbine. Inadutsa X-ray koma inalephera poyesa kupsinjika maganizo. Tidasintha chilichonse: kutentha kwa kutentha, kutentha kwa chipolopolo, kapangidwe ka alloy. Palibe chomwe chinagwira ntchito nthawi zonse. Pomaliza, mu mphindi ya kukhumudwa, tinayang'ana pa ndondomeko ya sera yokha. Chipata cha jakisoni chidalumikizidwa pomwe panali zovuta, ndikupanga malo am'deralo. Mwa kungosuntha malo omwe ali pachipata ndikuwonjezera kuzizira pang'ono mu nkhungu pamalopo, tinalozera kutsogolo ndikuchotsa porosity. Vuto silinali chitsulo; inali geometry yotentha yomwe tidapanga.
Kulephera kwina kwachikale ndikungoganiza kuti zonse pambuyo pokonza ndizofanana. Tidatumiza gulu la ma 316 ochita masewera kuti angopereka kwa wogulitsa watsopano. Iwo ankagwiritsa ntchito nitric asidi kusamba, muyezo mchitidwe. Koma kusamba kwawo kunali koyipitsidwa ndi ma kloridi a ntchito ya m’mbuyomo. Chotsatira chake chinali gawo lachiphamaso lomwe linalephera kuyesa kopopera mchere mochititsa chidwi. Kuponyera kunali komveka, koma zowongolera zathu zogulitsira sizinali choncho. Tsopano, timayenereza ogwirizana nawo molimbika monga momwe timachitira tokha. Kuwongolera komaliza uku, m'malingaliro mwanga, ndi chizindikiro cha wogula wokhwima. Ndilo mtundu wa kuyang'anira kwathunthu komwe kampani imapanga zaka zoposa 30 mu bizinesi, kuyang'anira zonse kuchokera ku chitsulo chachitsulo ku ma aloyi achilendo pansi pa denga limodzi.
Kotero, pamene inu muyang'ana pa zitsulo zosapanga dzimbiri mwatsatanetsatane kuponyera, osangowona geometry yomaliza. Onani thanki ya slurry, ma chart a kutentha, kuyerekezera kolimba, cholumikizira pamakina a CNC, ndi maphunziro omwe adapambana movutikira kuchokera ku zolakwika zakale. Kulondola kumapezedwa, osaperekedwa, kudzera pamasitepe ang'onoang'ono chikwi, olamuliridwa komanso kumvetsetsa kwakuya komwe kuli luso lachilengedwe komanso komwe ayenera kukakamizidwa mwamphamvu pamzere. Ndizo zomwe mukuguladi.
