Mukayamba kuyang'ana makampani opanga zitsulo zosapanga dzimbiri, chinthu choyamba chomwe chimakukhudzani ndi angati omwe amati ndi akatswiri. Mawuwa amaponyedwa mozungulira kwambiri moti amayamba kutaya tanthauzo. Aliyense amalonjeza kulolerana kolimba, ma geometries ovuta, komanso kutsirizitsa kwapamwamba. Koma nditakhala zaka zambiri kumbali zonse zopezera ndi kupanga, ndaphunzira kuti wosiyanitsa weniweni mulibe m'kabukuka; Zili mu gritty, nthawi zambiri zosasangalatsa za kayendetsedwe ka kayendetsedwe kake, kumvetsetsa zinthu, ndi kuthetsa mavuto zomwe zimachitika pamene ndondomeko ya sera ikugwedezeka kapena chipolopolo chiphwanyika. Sikuti kungothira zitsulo; Ndiko kuyang'anira masitepe osavuta, odalirana pomwe cholakwika chimodzi chimatha kusiya gulu lonse. Makasitomala ambiri amabwera atakhazikika pamagawo omaliza a aloyi-monga 316L kapena 17-4 PH-zomwe ndizovuta, zedi, koma ndiye poyambira. Mtengo weniweni ndi khalidwe zimatsimikiziridwa kale kwambiri.
Pakatikati pa Njirayi: Kuposa Kuthira Chitsulo Chokha
Kuponya ndalama zenizeni, makamaka zitsulo zosapanga dzimbiri, ndikuvina kwaukadaulo ndi sayansi yankhanza. Njira yopangira chipolopolo ndi pomwe zonse zimayambira. Ndawonapo masitolo kumene malo okhala m'zipinda zamatope - chinyezi, kutentha - samayendetsedwa, ndipo amadabwa chifukwa chake mphamvu zawo zimasiyanasiyana. Pazigawo zodalirika kwambiri, tinene za ntchito zam'madzi kapena zopangira mankhwala, kusagwirizana ndiko kupha. Chipolopolo si chidebe chokha; ndizomwe zimatanthawuza kutha kwapamwamba ndi kulondola kwa dimensional. Chigoba chosauka chimatsogolera pakuwotchera, kulowa kwachitsulo, ndi mtengo womaliza wowopsa womwe ungathe kuwirikiza mtengo wagawo.
Apa ndipamene kuya kwa kampani kumawonetsa. Ndikukumbukira pulojekiti ya choyikapo pampu yomwe imafuna CF8M yopanda banga. Ma prototypes oyambira kuchokera kwa ogulitsa amawoneka angwiro, koma adalephera pakuyesa kukakamiza. Nkhani yake? Micro-shrinkage. Wogulitsayo anali kugwiritsa ntchito njira yokhazikika komanso yokwera yachitsulo chosapanga dzimbiri, koma magiredi austenitic ngati CF8M ali ndi mawonekedwe okhazikika. Kukonzekera sikunali kokongola; zinali za kuyikanso zokwera ndikusintha kutentha kwa kuthirira kutengera kutentha kwenikweni kwa zinthu. Mtundu woterewu umachokera ku zochitika, osati pamanja.
Ambiri makampani opanga zitsulo zosapanga dzimbiri adzapereka ntchito yopangira mapeni awo kapena kumanga zipolopolo. Komabe, okhoza kwenikweni amasunga zonse m'nyumba. Zimawapatsa ulamuliro. Mukapita kumalo osungira, musamangoyang'ana ng'anjo. Funsani kuti muwone makina osindikizira phula, akasinja amatope, malo opangira masiko. Ukhondo ndi dongosolo (kapena kusowa kwake) komweko kumakuuzani zambiri kuposa satifiketi yamtundu uliwonse pakhoma.
Ma Nuances a Zinthu ndi Special Alloys Factor
Chitsulo chosapanga dzimbiri ndi banja, osati chinthu chimodzi. Kuyankha kwa makina ndi kutentha kwa 304 ndi mayiko kupatula 15-5 PH. Vuto lalikulu ndikuwachitira zonse chimodzimodzi pochita maopaleshoni otaya. Ndagwirapo ntchito ndi a zosapanga dzimbiri ndalama kuponya wothandizira pa thupi la valve mu duplex zitsulo 2205. Kuponyera kunali komveka, koma iwo ankagwiritsa ntchito njira yothetsera annealing cycle yomwe imatanthawuza 316. Idawononga mphamvu ya ferrite-austenite ndi kukana kwa dzimbiri. Tinayenera kusiya zambiri. Limenelo linali phunziro la $40,000 pazambiri zazitsulo.
Ichi ndichifukwa chake kutchulidwa kwa ma aloyi apadera monga opangidwa ndi faifi tambala kapena opangidwa ndi cobalt pakampani yamakampani ndi chizindikiro chofunikira. Zikusonyeza kuti amayenera kuthana ndi zovuta zosungunuka, kuthira, ndi kutentha kwa isostatic-pressing (HIP). Ngati atha kuthana ndi Hastelloy C-276, ndiye kuti kuponya 316L ndikuyenda paki kwa iwo. Zipangizo ndi kudziwa mmene kukula, osati pansi.
Tengani kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd.. Iwo amandandalika zosapanga dzimbiri ndalama kuponya pambali pa kuponya nkhungu ndi CNC Machining, ndikuyitanitsa makatani a cobalt ndi faifi tambala. Ndiko kuphatikiza kothandiza. Zimandiuza kuti mwina amamvetsetsa kuti gawo loponyedwa nthawi zambiri limangokhala chinthu chomaliza. Kukhala ndi makina m'nyumba ndi mwayi waukulu pakuwongolera mawonekedwe komanso nthawi yotsogolera. Mukupewa kuloza chala pakati pa maziko ndi malo ogulitsira makina pamene kulolerana kuphonya. Kudzinenera kwawo kwazaka 30 popanga ndi kukonza kukuwonetsa kuti mwina adawonapo zambiri mwazokhudza mutu ndipo (mwachiyembekezo) adaphunzira kuzipewa.
Ubwino wa Integration Machining
Izi zimandifikitsa ku mfundo yanga yotsatira: cholumikizira chopanda msoko pakati pa kuponyera ndi makina. Ndi mtengo waukulu, womwe nthawi zambiri umachepetsedwa. Nthawi ina ndinapezako ma flanges opangira zitsulo zosapanga dzimbiri kuchokera kumalo odzipatulira. Zojambulazo zinali zabwino, koma malo opangira makinawo sanapangidwe bwino. Malo ogulitsa makina osiyana adavutika kuti agwire ntchito yokhazikika, zomwe zidapangitsa kuti 30% akakane. Vuto linali vuto la mapangidwe omwe amayenera kugwidwa panthawi yokonza ndondomeko yoponya.
Pamene a makampani opanga ndalama amayendetsanso madipatimenti a CNC, akatswiri awo opanga njira amaganizira za gawo lonselo. Adzapereka malingaliro osintha ma angle owoneka bwino kapena amapangira kusintha mzere wotsatsira kuti apange datum yabwinoko kuyambira pachiyambi. Amapanga ma geting system osati chitsulo chomveka komanso momwe chidzachotsedwera komanso komwe zikhomo zizikhala. Mtundu wa QSY woperekera zonse zipolopolo za nkhungu / zopangira ndalama komanso makina a CNC pansi pa denga limodzi ndi mtundu womwewo wa ntchito zophatikizika zomwe zimathetsa zovuta zomwe zabisikazi. Sizokhudza kuphweka kokha; ndi za kutsimikizika kwabwino komangidwa.
The Machining of cast stainless ali ndi zidule zake. Zomwe zimapangidwira zimatha kukhala zolimba, zolimbikira ntchito ngati 304 zitha kukhala zankhanza pazida, ndipo kulimba kosasinthasintha kwa malo oponyedwa kungayambitse macheza a zida. Wothandizira ophatikizidwa apanga ma feed a eni ake, kuthamanga, ndi njira zopangira zawo. Chidziwitso chokhazikika chimenecho sichimakhalapo pamene zigawozo zatumizidwa ku malo ogulitsa makina opanga mankhwala.
Quality Perception vs. On-the-Ground Reality
Certification ndi gawo lazakudya. ISO 9001, PED, AD2000—ndiwofunika pochita bizinesi m’magawo ambiri, koma sakutsimikizira kuti adzachita bwino. Amatsimikizira dongosolo lolembedwa. Ubwino weniweni uli mu ma protocol osawononga (NDT) komanso kufunitsitsa kuwaumiriza. Kodi kampaniyo imayesa 100% polowera utoto pamagawo onse ovuta? Kodi ali ndi X-ray m'nyumba kapena ultrasound, kapena amazipereka kunja? Kutumiza kunja kumatha kuwonjezera masiku ndikuchepetsa kubwereza kobwereza ndondomeko.
Ndikukumbukira ndikuchita kafukufuku wolonjeza zosapanga dzimbiri ndalama kuponya wogulitsa. Zolemba zawo zinali zabwino kwambiri. Koma pansi, ndidawona wantchito atatsala pang'ono kugaya chivundikiro pamwamba pa valavu popanda kulemba kaye kapena kupeza chilolezo cha QA. Kuchita kamodzi kokhako kunasokoneza dongosolo lawo lonse lofufuza. Chikhalidwe chaubwino pamalo ogulitsira, kupatsa mphamvu antchito kuyimitsa mzere, ndizofunikira kwambiri kuposa satifiketi yomwe ili pamalo olandirira alendo.
Kutalika kwabizinesi, monga zaka 30 za QSY, nthawi zambiri zimagwirizana ndi chikhalidwe chokhwima. Apulumuka chifukwa mwina adakonza zovuta zomwe zimachotsa makampani atsopano. Iwo mwina adayikapo ndalama pazida ngati ma spectrometer otsimikizira za chemistry ndipo alinganiza phula ndi zomangira zawo kuti achepetse kusinthasintha. Izi sizowoneka bwino, koma ndizomwe zimapangitsa kampani kukhala yodalirika.
Mfundo Zothandiza pa Chibwenzi
Ndiye, mumagwira ntchito bwanji ndi makampaniwa moyenera? Choyamba, perekani chithunzi chonse. Osangotumiza zojambula. Tchulani malo ogwiritsira ntchito-kutentha, kuthamanga, media, cyclic loading. Izi zimadziwitsa chilichonse kuyambira pakusankhidwa kwa aloyi mpaka kufunikira kwa HIP. Chachiwiri, tsegulani malingaliro a Design for Manufacturability (DFM). Katswiri wabwino wopangira zida atha kuwonetsa kusintha kwa makulidwe pang'ono kapena kusintha kwa ma radius komwe kumapangitsa kuti ntchito ikhale yabwino komanso kuchepetsa mtengo, osataya ntchito.
Chachitatu, konzekerani zoyembekeza pamapeto pake. As-cast surface roughness (Ra) pakupanga ndalama ndizabwino, koma simaliro agalasi opangidwa ndi makina. Ngati mukufuna Ra 1.6 pa bore, tchulani ngati pamwamba pamakina. The foundry ndiye kusiya katundu moyenerera. Kumveketsa bwino apa kumalepheretsa kukhumudwa.
Pomaliza, penyani ubalewo ngati mgwirizano. Zotsatira zabwino kwambiri zomwe ndakhala nazo zidabwera chifukwa chothana ndi mavuto. Panali nyumba yovuta yomwe timafunikira mu 17-4 PH chikhalidwe H1150. Zoyambira zoyamba zinali zowopsa. Kupyolera mu kafukufuku wophatikizana - katswiri wawo wazitsulo ndi injiniya wathu - tidafufuza mpaka kusakanikirana kwa kuzizira pambuyo pothira ndi mapangidwe a ngodya yakuthwa yamkati. Tidasintha mapangidwe (kuwonjezera fillet) ndipo adasintha njira yawo yogwedeza. Gawoli lakhala likupanga zaka zambiri tsopano. Ndiwo phindu lochita zinthu ndi waluso makampani opanga zitsulo zosapanga dzimbiri-amakhala chowonjezera cha gulu lanu la uinjiniya.
Ndi malo odzaza anthu, koma opambana si omwe ali ndi mawebusayiti apamwamba kwambiri. Ndiwo omwe ali ndi akasinja oyendetsedwa ndi slurry, metallurgist m'nyumba, ma cell ophatikizika a CNC, ndi malingaliro anzeru, othetsa mavuto omwe amalemekezedwa kwazaka zambiri, monga momwe mbiri yogwirira ntchito imatanthauzidwa ndi kampani monga QSY. Zojambulazo zili mwatsatanetsatane, ndipo zitsulo zimanena zoona nthawi zonse.
