Mumamva zambiri za kulimba kwa chitsulo champhamvu yokoka, koma macheza ambiri amaphonya mfundo. Sizokhudza kalasi yachitsulo kapena makulidwe a khoma. Zochitika zenizeni, kuchokera pomwe ndimayima pambuyo pa zaka makumi atatu muzoyambitsa, ndikusuntha kuchoka ku kukhazikika ngati chinthu chokhazikika mpaka kuchiyang'anira ngati njira yosinthika, yokhudzidwa kwambiri ndi kusintha kosaoneka bwino kwa njira ndi zisankho zoponyedwa pambuyo. Aliyense amafuna gawo lomwe limakhalapo kwanthawizonse, koma njira yomwe iliko ikukhala yowonjezereka.
Lingaliro Lolakwika la Zinthu Monga Mfumu
Makasitomala akamafunsa za kulimba, chinthu choyamba amalumphirako ndi kuchuluka kwazinthu. Ndipatseni Class 35 kapena kuposa. Zoonadi, mphamvu zolimba ndizofunikira. Koma ndawonapo ma projekiti ambiri pomwe amatchula chitsulo chapamwamba kwambiri, kenako amasokoneza china chilichonse kuti apulumutse masenti angapo pagawo lililonse. Chemistry yosungunuka imasinthidwa kuti ikhale nthawi yothira mwachangu, katemera amathamangira-mwadzidzi, chitsulo chamtengo wapatalicho chimakhala chodzaza ndi graphite kapena ma carbides ochulukirapo. The mphamvu yokoka yachitsulo chachitsulo tulukani kuyezetsa kuti mufotokoze pamapepala, koma mawonekedwe ake ndi osalimba. Iwo amalephera m'munda pansi pa cyclic loading, ndipo aliyense amadzudzula zakuthupi. Sizinali zinthu; inali njira yozungulira zinthu.
Tinali ndi mlandu zaka zingapo kumbuyo kwa thupi la hydraulic valve. Zolembazo zinali zolimba, zimafuna kukakamizidwa bwino. Mayendedwe oyambilira adagwiritsa ntchito chitsulo chokhazikika cha nkhumba chotenthetsera bwino kwambiri komanso choteteza chomwe tidapanga m'nyumba. Zigawo zapambana mayeso onse. Wopikisana naye amatsitsa mtengo wathu kwambiri. Pambuyo pake tidapeza kuti adagwiritsa ntchito chitsulo chapamwamba kwambiri koma amadula ngodya pakuwongolera kutentha kwa nkhungu komanso kuthamanga. Ziwalo zawo zidapambana mayeso oyambira a hydrostatic koma zidayamba kuwonetsa ming'alu yaying'ono pambuyo pa kukakamiza kwa 500. Zathu zinali zikuyendabe pa 5000+. kasitomala anabwerera. Kodi tikuphunzirapo chiyani? Mzere wachitsulo ndi wocheperako kuposa momwe mumachitira panthawi yachitsulo kuponya mphamvu yokoka ndondomeko.
Izi zimatsogolera kumayendedwe enieni oyamba: kuyang'ana pa kusasinthika kwazinthu monga dalaivala wokhazikika. Ndi za kuwongolera kusintha kulikonse - makulidwe a nkhungu, kuthira kutentha, kuzizira mu nkhungu - ndi chidwi chachipembedzo. Odula deta pa ng'anjo zathu ndi mizere yothira sizongowonetseratu; Ndimo momwe timalondolera vuto lolimba kubwerera ku 10-degree Celsius kutsika kwa kutentha kwa ladle kumapeto kwa kuthira.
Kumene Kukhazikika Kumapambana Kapena Kutayika: Geometry Yosawoneka
Kukhalitsa sikunapangidwe pa chitsanzo cha CAD; imayikidwa mu gawo. Uku ndikusintha kwakukulu pamaganizidwe. Mainjiniya amapangira ntchito, koma nthawi zambiri amapanga ma geometri omwe amapanga kupsinjika panthawi yolimba. Ngodya zakuthwa zamkati, kusintha kwadzidzidzi kwa magawo - izi ndizopha durability. Zomwe ndikuwona ndizogwirizana kwambiri nkhungu isanapangidwe. Tikuwononga nthawi yochulukirapo pa pulogalamu yoyeserera osati kungopewa zolakwika zowonekera, koma kutengera kupsinjika kwa kutentha pakuzizira.
Mwachitsanzo, makoma a kompresa yolemetsa. Kapangidwe kake kanali kokongola, kosunga nthiti zolemera. Koma kuyerekezera kwathu kunawonetsa kuthekera kwakukulu kwa kung'ambika kotentha pamphambano za nthiti. Tidapereka malingaliro owonjezera ma fillets ang'onoang'ono, osati kuti agwiritse ntchito mphamvu, koma kuti azilimbitsa panthawi yolenga. Gulu lojambula linakana-linawonjezera kulemera kochepa. Tinapanga batch imodzi momwe ilili, ndipo imodzi yokhala ndi zosintha zathu. The as-batch inali ndi 30% scrap rate kuchokera ku ming'alu yomwe imawonekera poyang'aniridwa ndi utoto. Gulu losinthidwa? Pafupi ndi zero. The kukhazikika Kutulutsa mawu kunali kokulirapo chifukwa idapulumuka kubadwa kwake popanda zolakwika zamkati.
Kuyerekeza kokhazikikaku kukukhala gawo losakambirana kwa ife pa QSY. Ndi ndalama zomwe zimalipira popewa zoopsa, zolakwika zobisika zomwe zimayambitsa kulephera kwamunda. Imasuntha kukhazikika kumtunda.
The Post-Casting Gambit: Chithandizo cha Kutentha ndi Machining
Pano pali mkangano. Kuchepetsa kupsinjika maganizo. Mashopu ena amachitenga ngati bokosi lovomerezeka kuti alembe. Ena amadumphadumpha kuti asunge nthawi ndi mphamvu. Maganizo athu asintha. Tsopano tikuwona ngati chida chosankha. Kwa mawonekedwe ovuta, otsekedwa ngati nyumba zapampu, ndizofunikira. Kupanikizika kotsalira kochokera ku kuzizira kosiyana kungakhale kwakukulu. Kudumpha kuchepetsa nkhawa kuli ngati kupiringa kasupe mkati mwa gawolo; makina adzamasula, kupangitsa kusokoneza, ndipo katundu wa mu-utumiki adzagwira ntchito pa gawo lomwe linasindikizidwa kale.
Koma tachitanso zinthu mopambanitsa. Chingwe chosavuta, chotseguka chopangidwa ndi chitsulo chotuwira chinadutsa njira yochepetsera nkhawa. Sizinangopumula zopsinjika; idafewetsa pang'ono zakuthupi, kuchepetsa kukana kwake kuvala m'dera lofunika kwambiri. Inali nkhani yogwiritsira ntchito njira yokhazikika popanda kulingalira. Tsopano, timasankha kutengera geometry, kusiyanasiyana kwa makulidwe a khoma, komanso kuya kwa makina omaliza. Nthawi zina, kwa gawo lokhazikika, losavuta, kuzizira kolamulidwa mu nkhungu ndikokwanira. Ntchito yosankha iyi ndi njira yolowera mwanzeru, osati kungowonjezera, kukonza.
Ndiye pali makina. Gawo lopangidwa bwino likhoza kuwonongedwa ndi makina aukali. Tidaphatikiza makina a CNC pang'ono kuti tiwongolere gawo lomalizali. Kudula kwambiri, mwachangu pa a chitsulo chachitsulo gawo limatha kung'amba matrix a graphite pamtunda, ndikupanga maukonde ang'onoang'ono omwe amakhala malo oyambira kutopa. Akatswiri athu amakina amadziwa kugwiritsa ntchito ma geometries ndi ma feed/liwiro pakupanga kwathu. Sizongokhudza kugunda gawo; ndi za kusunga umphumphu tidagwira ntchito molimbika kuti tipange poyambira.
The Alloying Subtlety: Si Chilichonse ndi Superalloy
Nthawi zonse zimakhala za aloyi achilendo. Koma pazinthu zambiri zamafakitale, kukhazikika komwe kumapindula kuchokera ku chitsulo cha imvi kapena ductile kumakhala kokhudza finesse kuposa mphamvu yankhanza. Zowonjezera zazing'ono zamkuwa, tini, kapena chromium. Sitikulankhula za kusamukira zitsulo zopangidwa ndi nickel, koma za kusintha matrix.
Tinkagwira ntchito pa mbale yopangira makina otumizira migodi. Chitsulo choyera chotuwira chinavala mofulumira kwambiri. Chitsulo chachitsulo chinali cholimba kwambiri komanso chokwera mtengo. Tidakhazikika pachitsulo chotuwa ndikuwonjezera kowongolera kwa chromium ndi mkuwa. Chromium imalimbikitsa matrix olimba, a pearlitic kuti asakhumudwe, pomwe mkuwa umayenga graphite ndikuwonjezera mphamvu popanda kuphulika kwakukulu. The durability trends apa ndikupita ku micro-alloying ya mbiri yazachuma, yomwe nthawi zambiri imatsogozedwa ndi zaka zoyeserera ndi zolakwika muzolemba zathu. Ndizowoneka bwino kuposa kunena kuti timagwiritsa ntchito ma superalloys, koma nthawi zambiri zimakhala zogwira mtima komanso zotsika mtengo pakuzigwiritsa ntchito.
Apa ndipamene zochitika za foundry sizingalowe m'malo. Simungangotenga maphikidwe awa kuchokera m'bukhu lamanja. Zimadalira gwero lanu lachitsulo, machitidwe anu osungunuka, ngakhale momwe nyengo yanu imakhudzira kuyanika nkhungu. Msuzi wachinsinsi nthawi zambiri umakhala zaka makumi angapo a data yosungidwa.
Kulephera Monga Mphunzitsi Wabwino Kwambiri: Mbiri Yaumwini
Kumayambiriro kwa nthawi yanga kuno ku Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), tinali ndi kulephera kwakukulu komwe kunasintha njira yathu. Gulu la gearbox yachitsulo cha ductile chimakwirira ntchito yam'madzi. Adapambana macheke onse a QA. Miyezi isanu ndi umodzi tikugwira ntchito, tinalandira foni yowopsa: ming'alu inali kuwoneka mozungulira mabowo a bawuti. Zinali tsoka.
The post-mortem inali yankhanza. Zinthuzo zinakumana ndi nodularity ndi kalasi. Mapangidwe ake anali abwino. Wolakwa? Kusintha kwa makina omangira mchenga kupita ku chinthu chatsopano, chachangu. Zinathandizira kupanga nkhungu pang'ono, koma zidasintha kuzizira kokwanira m'magawo ovuta ozungulira mabwana a bawuti. Zinapanga zone ya carbide yokwera pang'ono, ndikupangitsa kuti ikhale yolimba. Kupanikizika kosalekeza kuchokera ku kugwedezeka kwa injini kunapeza kuti kufooka. Tinataya kasitomala, tinalipira zogula zina, ndipo tinatsala pang'ono kutaya mbiri yathu.
Kulephera kumeneko kunatikakamiza kukhazikitsa ulamuliro wosintha. Kusintha kulikonse - chomangira chatsopano, choyikira chatsopano, zida zatsopano za ladle - tsopano zidutsa gulu loyendetsa ndege ndikugawa mokhazikika komanso kusanthula pang'ono. Sitingoyesa kuzinthu zokhazikika; timayang'ana masinthidwe obisika a microstructural. Phunziro lopweteka limenelo linachita zambiri kudziko lenileni kukhazikika wathu mphamvu yokoka yachitsulo chachitsulo kuposa buku lina lililonse. Ndi chikhalidwe chobadwa kuchokera ku zipsera: kulimbikira mwadongosolo pakuthamangitsa zing'onozing'ono.
Ndiye, mayendedwe akulowera kuti? Kutali ndi mayankho osavuta. Kuwongolera njira zophatikizika, kuyambira kuyerekezera kupita kumankhwala osankha kutentha kupita ku makina odekha. Kupita ku micro-alloying kutengera mbiri yakale kwambiri. Ndipo koposa zonse, kulemekeza kukhazikikako sizinthu zomwe mumayesa gawo; ndi chikhalidwe chomwe mumapangira. Ndiko kuwongolera kotopetsa, mwanzeru, kosakambitsirana kwamitundu zana yomwe palibe amene amawona-kufikira gawolo likugwirabe ntchito mosalakwitsa patapita zaka zambiri. Ndiwo mayendedwe enieni. Mutha kupeza zina mwazanzeru zathu zomwe zimagwiritsidwa ntchito pazonse zomwe tafotokoza patsamba lathu tsngtaocnc.com, koma chidziwitso chenicheni, monga nthawi zonse, chiri pa maziko.
