Anthu ambiri akamva za 'kutayika kwa phula', amajambula njira yolunjika, yomwe imakhala yachikondi: kupanga chitsanzo cha sera, kupanga chigoba cha ceramic, kusungunula sera, kutsanulira zitsulo. Chowonadi m'malo opangira, makamaka ma alloys ovuta, ndikukambirana kosalekeza pakati pa sayansi yazinthu, mphamvu zamagetsi, komanso magwiridwe antchito. Ndi dongosolo, osati sitepe imodzi, ndipo ndipamene ofotokozera ambiri komanso mainjiniya atsopano amapita. Amayang'ana kwambiri kuponyedwa komweko koma amapeputsa chilengedwe - kapangidwe ka sera, kuwongolera nyengo m'chipinda chamatope, njira yochepetsera, kupindikira kwa nyundo - zomwe zimatsimikiziradi ngati mupeza ukadaulo kapena nyenyeswa. Popeza tadutsa mu izi kwa zaka zambiri, gloss imatha msanga; chomwe chatsalira ndikuyang'ana pa mndandanda wa anthu odalira.
Pakatikati pa Dongosolo: Zonse Zili Zokhudza Kuwongolera ndi Kubwereza
Lingaliro loyamba lolakwika losiya ndikuti kuponya ndalama ndi luso. M'malo ogulitsa ntchito zosakanikirana, zotsika kwambiri, mwina. Koma kwa kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., yomwe yakhala ikugwira ntchito kwa zaka zoposa 30, ndi ndondomeko yoyendetsedwa ndi mafakitale. 'Dongosolo' limayamba kalekale chitsulo chisanatsanulidwe. Tikulankhula za magawo a jakisoni wa sera. Kutentha, kupanikizika, ndi kusunga nthawi yobaya phula lapatani zimakhudza kukhazikika kwa mawonekedwe ndi kutha kwa pamwamba. Kusiyanasiyana kwa madigiri angapo kungayambitse kupotoza kosawoneka bwino komwe kumaphatikizana pambuyo pake. Ndawonapo mapulojekiti akulephera chifukwa kutentha kwa chipinda cha sera sikunakhazikike, zomwe zinapangitsa kuti mapangidwe apangidwe asokonezeke kwambiri.
Kenako pamabwera ntchito ya slurry ndi stucco. Uku sikungodumphira ndi kudumphadumpha. Kukhuthala kwa slurry yoyamba, chiŵerengero cha ufa wa zircon / silika binder, chinyezi m'chipinda choviyira - kusintha kulikonse ndi mfundo yomwe muyenera kuyimba. Kwa ma superalloys opangidwa ndi faifi tambala kapena a cobalt, omwe QSY imachita pafupipafupi, chipolopolocho chimafunika kupirira kutentha kwambiri kuthirira popanda kugunda kapena kuchitapo kanthu ndi chitsulo. Nthawi zambiri timagwiritsa ntchito slurry yosakanikirana ndi silika pazinthu izi, koma nthawi yowuma pakati pa malaya ndiyofunikira. Lifulumizitse, ndipo umatchera chinyontho; dikirani motalika kwambiri, ndipo zigawo sizimalumikizana bwino. Ndi nyimbo yomwe mumaphunzira poyang'ana zipolopolo, osati mawotchi okha.
Gawo la dewaxing ndi pomwe gawo la 'lost wax' limachitika, ndipo ndi nthawi yachiwawa kwa chipolopolo. Njira ziwiri zazikuluzikulu ndi autoclave (steam) ndi flash fire. Iliyonse ili ndi malo ake. Pamagulu a sera okhuthala, kuwombana kungayambitse ming'alu chifukwa cha kutenthedwa kwa kutentha. Nthawi zambiri timakonda autoclave ya ma geometries ovuta omwe amapezeka mwathu chipolopolo nkhungu kuponyera ndi kuponya ndalama ntchito, monga mwaulemu. Koma ngakhale zili choncho, kuchuluka kwa ma rampu ndi kupanikizika kuyenera kufananizidwa ndi mtundu wa sera. Kugwiritsa ntchito sera yosungunuka kwambiri? Kuthamanga kwambiri kwa nthunzi mwachangu kwambiri, ndipo kukulitsako kumatha kuswa chipolopolo chobiriwira. Ndikuchita bwino komwe kumamveka kwambiri kuposa kachitidwe nthawi zina.
Zinthu Zakuthupi: Chifukwa Chake Kusankha kwa Aloyi Kumalamulira Njirayi
Inu simungakhoze kulekanitsa kutayika kwa sera kuchokera ku zinthu zomwe zikuponyedwa. Njira yopangira chitsulo cha ductile ndi yosiyana kwambiri ndi ya alloy-based alloy ngati Inconel 718. Iyi ndi mphamvu yaikulu pa malo ngati QSY. Ndi zitsulo zosapanga dzimbiri, cholinga chake ndikuteteza kuphulika kwa pamwamba pa chipolopolo, kotero titha kugwiritsa ntchito mpweya wosalowerera kapena wothira oxidizing pang'ono. Koma ndi ma alloys okhazikika ngati titaniyamu (ngakhale sitimayiponya, mfundoyi imagwira ntchito pazitsulo zathu za nickel), mukulimbana ndi mapangidwe a alpha-case. Kupangidwa kwa zipolopolo kumakhala kofunika kwambiri - nthawi zambiri kumasunthira ku yttria kapena malaya ena achilendo.
Kwa zitsulo wamba ndi zitsulo zosapanga dzimbiri, vuto nthawi zambiri limakhala kudyetsa ndi kuchepa. Kapangidwe ka zitseko, komwe ndi gawo la gulu la sera, ndipamene chidziwitso chenicheni chazitsulo chimadza. Sichingokhudza kulowetsa zitsulo mubowo; ndi za kupanga kulimba kolunjika. Ndimakumbukira nyumba yapampu mu 17-4PH yosapanga dzimbiri yomwe imangowonetsa porosity mu flange wandiweyani. Tidaupanganso mtengo wa sera, ndikuwonjezera kuziziritsa mu chigoba cha ndalama pafupi ndi malo ovuta kuti tiziziziritsa mwachangu. Zinagwira ntchito, koma zidawonjezera mtengo komanso kupanga zipolopolo zovuta. Dongosololi limayenera kusintha.
Kugwira ntchito ndi ma alloys apadera monga Stellite (cobalt-based) kumayambitsa wosanjikiza wina: kuthira kutentha. Ma aloyiwa ali ndi "kutentha kwambiri" kocheperako - kozizira kwambiri, ndipo sikudzaza magawo owonda; kutentha kwambiri, ndipo amatha kuwononga mkati mwa chipolopolo, ndikupanga zolakwika zophatikizika. Mchitidwe wathu wosungunula, kaya wogwiritsa ntchito ng'anjo zolowera, amawunikidwa pagulu lililonse la alloy. The logbooks kwa zaka zambiri akuthamanga pa tsngtaocnc.com Ndiwofunika kwambiri ngati zida, zomwe zimapereka mbiri yakale yazomwe zimagwira ntchito ndi zomwe sizili ndi magiredi enieni.
Ulalo Wovuta: Kuphatikizira CNC Machining mu Casting Workflow
Apa ndipamene zoyambira zambiri zamasewera zimasokonekera, ndipamene ntchito yophatikizika imawonetsa phindu lake. A kutaya sera ili pafupi konse gawo lomaliza. Ili ndi zotsalira za zipata, zipsepse zazing'ono zomwe zingatheke, ndipo imafunikira malo ovuta opangidwa kuti azitha kulolerana molimba. Ku QSY, kukhala ndi CNC makina m'nyumba sikophweka; ndichofunikira pakuwongolera khalidwe. Chifukwa chiyani? Chifukwa makina opanga makina amapereka mayankho enieni enieni pakumveka kwamkati kwa kuponya.
Ngati chida chikatha mwadzidzidzi pamalo enaake a ma castings angapo, chimawonetsa malo olimba kapena gulu lophatikizika kuchokera pakuponya. Ndemanga zachidulezi sizingalowe m'malo. Tikhoza kufufuza nkhani Machining kubwerera enieni chipolopolo mtanda, kusungunula kutentha nambala, kutentha kuthira analowa tsiku limenelo. Popanda kuphatikizika koyima uku, kuzungulira kwa mayankho kumasokonekera, ndipo zovuta zimavuta kuzizindikira ndikuzithetsa kwamuyaya.
Komanso, kamangidwe ka chitsanzo sera palokha nthawi zambiri amakhudzidwa ndi makina zofunika. Titha kuwonjezera katundu ('chilolezo cha makina') m'malo enaake podziwa kuti dipatimenti yathu ya CNC imaliza. Kapena, titha kuyika gawolo pamtengo wa sera kuti tichepetse nthawi yokonza makina pambuyo pake. Kugwirizana kumeneku pakati pa pansi ndi malo ogulitsira makina ndizomwe zimatembenuza kuponya bwino kukhala gawo lodalirika, lochita bwino kwambiri. Ndiko kusiyana pakati pa kupanga mawonekedwe ndi kupanga gawo logwira ntchito.
Zolephera Wamba ndi Maphunziro Amene Amapereka
Aliyense amene sanapange nyenyeswa sanapange kalikonse. Mu kuponya ndalama dongosolo, zolephera ndi aphunzitsi okwera mtengo. Kusweka kwa zipolopolo pakuwotcha kapena kuwombera ndikwabwino kwambiri. Nthawi zambiri, zimayambira pakuuma kosakwanira pakati pa malaya otayirira, makamaka m'malo achinyezi. Timalimbana ndi izi ndikuchotsa chinyezi m'malo oviyira - njira yosavuta, koma imodzi yomwe mumangoyigwiritsa ntchito mutataya zipolopolo zingapo.
Zowonongeka zachitsulo monga shrinkage porosity kapena misozi yotentha ndi gulu lina. Izi nthawi zambiri zimalozera mmbuyo ku mageti ndi kukwera, kapena kutentha kothira. Chochitika chosaiŵalika chinali thupi la valve mu duplex zitsulo zosapanga dzimbiri. Tinapitirizabe kupeza micro-porosity mu malo otentha. Mtundu wa sera ndi chitseko zimawoneka ngati zomveka. Kupambanako kudabwera pomwe tidawona momwe chipolopolo chimawombera. Zinapezeka kuti kutentha kwapamwamba sikunali kokwanira kupsereza zinthu zotsalira zapakatikati kuchokera pakatikati, ndikupanga chotchinga pang'ono cha gasi chomwe chimalepheretsa kudya. Kutalikitsa nthawi yowotchera kuwombera kunathetsa. Kodi tikuphunzirapo chiyani? Vuto sinthawi zonse pomwe mumangoyang'ana koyamba - limatha kukhala pamwamba pakukonzekera zipolopolo.
Kusalondola kwa dimensional ndikupha pang'onopang'ono. Sizingapangitse kukanidwa kotheratu, koma kumapha phindu pogwiritsa ntchito makina ochulukirapo. Izi nthawi zambiri zimabwerera ku kukhazikika kwa sera. Kugwiritsa ntchito phula lobwezeretsedwanso popanda kuyesa kutsika kwake kwa geometry yatsopano ndi vuto lofala. Tsopano timayesa mwamphamvu misanganizo yatsopano ya sera kapena kuwunika kukalamba kwa kaphatikizidwe kathu kameneka, ndikusintha pang'ono pazida za jakisoni kuti tibwezere. Ndi kusinthasintha kosalekeza kwa sitepe yoyamba mu dongosolo.
The Real-World Ecosystem: Kuchokera Kufufuza Mpaka Gawo Lomaliza
Ndiye, kodi dongosololi likuwoneka bwanji pochita ntchito yomwe yakhala nthawi yayitali? Zimayamba ndikuwunikanso zojambula ndi zinthu zina. Akatswiri pa QSY samangowona mawonekedwe; amawona kugawanika kwakukulu kwa kutentha, malo opanikizika omwe angakhalepo, ndi makina opangira makina. Mapangidwe a zida za sera akulinganizidwa, nthawi zambiri ndi malingaliro ochokera ku gulu la CNC pa fixturing. Sera imabayidwa ndi kuikidwa m'mitengo.
Kupanga zigoba kumayamba—njira yapang'onopang'ono yoviika, kuyika pansi, ndi kuyanika, yomwe ingatenge mlungu wathunthu kuti chigoba chachitsulo chikhale cholimba. Gulu lililonse limadulidwa. Kuwotcha ndi kuwombera kumasintha chipolopolo chobiriwira chosalimba kukhala nkhungu yolimba ya ceramic. Pakalipano, alloy yeniyeni-kaya zitsulo za carbon, 316 zosapanga dzimbiri, kapena alloy-based alloy-amakonzedwa ndikusungunuka pansi pamikhalidwe yoyendetsedwa. Kuthira ndikofulumira, koma kukhazikitsidwa ndi kutsimikizira kutentha sikuli.
Pambuyo pozizira, chipolopolocho chimachotsedwa, zigawozo zimadulidwa pamtengo, ndipo zimapita kumalo oyambirira (kuwombera, kudula). Kenako pakubwera chovuta kwambiri ku makina a CNC. Apa, gawolo limatsimikiziridwa motsutsana ndi kusindikiza. Kuyang'anira komaliza, kuphatikiza NDT ngati cholowetsa utoto, kumatseka lupu. Zonse kutayika kwa sera, choncho, ndi unyolo wophatikizika uwu: kupanga mapangidwe, kumanga zipolopolo, kusungunuka / kuthira, ndi kukonza pambuyo. Ulalo wofooka mu gawo lililonse umasokoneza gawo lomaliza. Ndi malingaliro athunthu awa, omangidwa pazaka makumi atatu zakuthana ndi zovuta m'magawo onsewa, omwe amatanthauza wothandizira, osati kutsanulira zitsulo mu nkhungu.
