Zowona, makamaka m'malo ogulitsa ntchito zosakanikirana, zotsika kwambiri, ndizoyipa kwambiri komanso zochulukirapo. Sikuti kusungunula zitsulo ndi kuzitsanulira; ndikukambirana kosalekeza pakati pa cholinga cha mapangidwe, machitidwe a zinthu, ndi fiziki youma ya zitsulo zozizira. Makasitomala ambiri amabwera akuyembekezera zozizwitsa kuchokera ku kutaya sera ndondomeko yokha, osazindikira kuti luso lenileni la foundry liri pakuyembekeza ndikuwongolera kusokonekera, kuyang'anira machitidwe olowera kuti achepetse zinyalala, komanso kudziwa momwe 17-4PH yosapanga dzimbiri idzacheperachepera ndi 316L. Ndiko komwe zaka zambiri zakupangitsa kuti manja anu akhale akuda.
The Core Illusion: Kulondola ndi Kusagwirizana Kwake
Mawu akuti 'investment casting' amagulitsa maloto a ukonde wowoneka bwino. Ndipo inde, mbali zambiri, zimakufikitsani pafupi kuposa kuponya mchenga kapena kupanga. Koma 'net-shape' ndi sipekitiramu. Ndikukumbukira pulojekiti yopangira zida za turbine, ntchito ya aloyi ya faifi. Chojambulacho chinafuna kulolerana komwe kumawoneka bwino pamapepala. Chitsanzo cha sera chinali changwiro. Chigobacho chinkawoneka bwino. Koma chitsulocho chikalowa, ma geometry amkati ovuta adapanga matenthedwe osagwirizana. Gawo lina litakhazikika mofulumira, kukoka maganizo pa khoma woonda. Chotsatira? Kupotoza kwa pafupifupi 0.5mm pa data yovuta - yokwanira kuchotsa batch. Phunziro silinali kuti zida zoponyera phula zotayika analephera; kunali kuti ndondomeko idayankhula. Tinayenera kubwereranso, kusintha ndondomeko ya sera ndi "kupotoza" kolipilira, mtundu wa kupotoza kopanda kanthu kutengera zomwe takumana nazo, kuti tipeze gawo lomaliza lachitsulo mkati mwake. Ndilo ntchito yosasangalatsa: forensic metallurgy ndi geometry kukonza.
Apa ndipamene moyo wautali wa foundry umafunika. Sitolo ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi mbiri yake ya zaka 30, yawona njira zolepherera izi kudutsa mazana a aloyi ndi mawonekedwe. Chikumbumtima chimenecho sichingalowe m'malo. Izo siziri mu bukhu; zili m'matumbo am'matumbo momwe opanga ma pateni ndi ogwiritsa ntchito ng'anjo. Amakhala ndi lingaliro la momwe chitsulo chamtali, chowonda mu chitsulo chimafunikira kutentha kosiyana ndi mawonekedwe okwera kuposa squat, chunky mu iron ductile iron. Simungathe kutengera zonse.
Kusankha zinthu ndi malo ena opangira mabomba. Makasitomala nthawi zambiri amasankha 'zitsulo zosapanga dzimbiri' kuti zisamachite dzimbiri. Koma uti? 304 ndiyosavuta kuponyera koma imatha kuvutika ndi mpweya wa carbide m'malo okhudzidwa ndi kutentha ngati kuwotcherera kudzafunika pambuyo pake. 316 imakana bwino koma ndiyosavuta kudyetsa panthawi yolimba, yomwe imakhala yocheperako. Pamalo owopsa, timakankhira ku ma alloys apadera - ma cobalt ndi faifi tambala. Khalidwe lawo mu kuponya ndalama ndondomeko ndi chilombo chosiyana palimodzi.

Gulu lopanga makina liyenera kudziwa momwe gawolo lidakhazikidwira ndikuwuka. Ayenera kudziwa komwe shrinkage porosity ingakhale (nthawi zambiri imakhala pamalo otentha, pafupi ndi malo omaliza kuti akhazikike). Izi zimawalola kukonzekera njira zawo zokonzera ndi zida kuti apewe maderawa kuti asamalizidwe kwambiri kapena kuwachotseratu pakadutsa koyamba. Pamene kuponyera ndi makina ali pansi pa denga limodzi, kuzungulira kwa mayankho kumachitika nthawi yomweyo. Katswiri wamakina amatha kubwereranso pamalo oyambira ndikunena kuti, Tikuvala zida zachilendo pa flange iyi, ndipo wopanga makinawo atha kuwona ngati pali vuto la kuuma kwanuko chifukwa chozizira kwambiri.
Synergy iyi ndi yofunika kwambiri pamtengo. Imasintha makina opangira zinthu kuchokera kwa ogulitsa zinthu kukhala wopereka mayankho. Kwa kasitomala, zikutanthauza mfundo imodzi yoyankha. Woyambitsayo sangayimbe mlandu wopanga makinawo chifukwa cha cholakwika chapansi panthaka, ndipo wopanga makinawo sanganene kuti mazikowo ndi olakwika. Iwo ayenera kuthetsa izo palimodzi. Zimakakamiza kuwona kwathunthu kwa chigawocho kuchokera ku chitsulo chosungunuka kupita ku gawo lomaliza.
Nkhungu ya Chipolopolo: Kavalo Wabata Wabata
Anthu amangoganizira za sera ndi zitsulo, koma chipolopolo ndi chomwe chimapangitsa kuti khalidwe likhale labwino. Njira ya 'kuponya chipolopolo cha chipolopolo' ya QSY imalemba limodzi ndi kuyika ndalama ikunena. Ngakhale zoona kutaya sera amagwiritsa ntchito matope a ceramic ndi stucco womangidwa mozungulira sera, kuumba zipolopolo nthawi zambiri kumagwiritsa ntchito nkhungu ya mchenga yopangidwa kale ndi utomoni kuti ikhale yosavuta. Koma mfundo za umphumphu wa zipolopolo ndi zapadziko lonse lapansi. Kulephera kwa zipolopolo ndizowopsa - kutha kwa chitsulo chosungunuka ndikoopsa komanso kokwera mtengo.
Mdierekezi ali mu kuyanika ndi kuwombera. Mofulumira kwambiri, ndipo chipolopolocho chimapanga ming'alu yaying'ono. Kuchedwa kwambiri, ndipo kupanga kumachepa. Kutentha kwa kutentha pamene chitsulo cha 1500 ° C chigunda chipolopolo cha kutentha kwa chipinda chimakhala chachikulu. Chigobacho chiyenera kukhala ndi mpweya wokwanira kuti mpweya ndi mpweya zituluke, koma osati pobowola kotero kuti zitsulo zilowetse, zomwe zimapangitsa kuti 'metal flash' iwoneke pamwamba. Kutengera izi moyenera pagulu lalikulu, lathyathyathya ndikosiyana ndi thupi lolimba, la chunky valve. Ndi njira yosinthidwa ndi kumverera ndi zochitika, nthawi zambiri ndi woyendetsa ng'anjo wamkulu yemwe amaweruza phokoso lomwe chipolopolo chimapanga chikaponyedwa.
Kwa ndime zovuta zamkati, pachimake (chomwe chimapanga geometry yamkati) ndi mutu wina. Iyenera kukhala yolimba mokwanira kuti ipirire kutuluka kwachitsulo koma kugwedezeka kotero kuti chitsulo chiwombeke popanda kuyambitsa misozi yotentha. Kugwiritsa ntchito zida zolakwika pakuponyera chitsulo chosapanga dzimbiri kungayambitse 'kusintha kwapakati' pakuthira, kusokoneza ndime zamkatizo ndikuchotsa gawolo. Mndandanda wa luso la foundry nthawi zambiri umatsutsana ndi izi, koma ndi mfundo yaikulu ya kusiyana kwaukadaulo.
Zinthu Zikasokonekera: Mwambo Wosokoneza
Kusanthula kulephera ndiyeso yeniyeni ya mettle ya foundry. Tiyerekeze kuti mwapeza batch yokhala ndi porosity yobalalika. Zomwe zimachitika nthawi yomweyo zitha kukhala kuwonjezera kutentha kwa kuthirira. Nthawi zina izo zimagwira ntchito. Nthawi zina, zimawonjezera kusungunuka kwa gasi muzitsulo, zomwe zimatuluka ngati thovu pamene zimazizira. Choyambitsa chenicheni chikhoza kukhala chinyezi mu chipolopolo chochokera ku tsiku lachinyezi lomwe silinaphike mokwanira, kapena kusintha pang'ono kutentha kwa jekeseni wa sera komwe kunasintha kumapeto kwa chithunzicho, kutsekereza mpweya.
Ndimakumbukira nkhani ina yachitsulo chopangidwa ndi chitsulo chomwe tinkangokhalira kutseka zotsekera (msoko wowonekera pomwe mitsinje iwiri yachitsulo idakumana koma osalumikizana). Ife tweaked chitseko, kuthamanga kutsanulira, kutentha kwachitsulo. Palibe. Pomaliza, wina anaganiza kuyang'ana chipolopolo chisanatenthe kutentha asanathire. Idazimitsa pafupifupi 50 ° C. Chigobacho chinkagwira ntchito ngati sink ya kutentha, kuziziritsa kutsogolo kwachitsulo mofulumira kwambiri. Kukonza izo kunakonza izo. Mfundo ndi yakuti, ndondomekoyi ili ndi mitundu yambirimbiri. Waluso zida zoponyera phula zotayika ali ndi mwadongosolo, pafupifupi matenda njira yothetsera mavuto, wobadwa kuona zolephera izi kale.
Ichi ndichifukwa chake mgwirizano wanthawi yayitali ndi maziko ndiofunika. Dongosolo loyamba litha kukhala ndi zosokoneza pomwe mbali zonse zimaphunzirira. Koma pofika pa dongosolo lachisanu, mazikowo ali ndi 'maphikidwe' a gawo lanu lenileni - magawo omwe akudziwa kuti amabweretsa chipambano. Chidziwitso chimenecho ndicho chinthu chenichenicho, osati mawonekedwe achitsulo okha.
Tsogolo Sili Kungochitika Mwangozi
Pali zokamba zambiri zamitundu yosindikizidwa ya 3D ndi zomanga zongopanga zipolopolo. Ndipo iwo ndi abwino kwa ma prototyping ndi ma geometries ena. Koma pamapangidwe ambiri, makamaka ndi magawo okhazikika, njira zachikhalidwe zikadali zolimba komanso zotsika mtengo. Makina ojambulira phula oyendetsedwa ndi munthu waluso yemwe amatha kumva kukokera pang'ono pa pisitoni ndikusintha kuthamanga molingana ndizovuta kusintha kwathunthu. Diso laumunthu lomwe limagwira kusagwirizana pang'ono mumsonkhano wapakati likadali chida champhamvu cha QC.
Chisinthiko chomwe ndimawona m'mayambidwe oyenerera monga QSY ndikuphatikizana kwa luso lakale ndi zida za digito. Kugwiritsa ntchito pulogalamu yoyeserera yolimba kuti musalowe m'malo, koma kuti mutsimikizire. Kugwiritsa ntchito CMM data kuchokera ku CNC makina siteji kuti idyetsenso mu ma aligorivimu owongolera ma pateni. Pansi poyambira masiku ano ndi wosakanizidwa: nsapato zafumbi ndi zowonera.
Pamapeto pake, mtengo wa a zida zoponyera phula zotayika zagona mu chiweruzo chake. Ndiko kudziwa nthawi yoyenera kutsatira pepalalo mokhazikika komanso nthawi yoyitanitsa mainjiniya ndikuwonetsa kusintha pang'ono kwa fillet komwe kungapulumutse milungu ingapo ya mutu. Ndizokhudza kuyang'anira kusatsimikizika kwachilengedwe kwakusintha zitsulo zamadzimadzi kukhala gawo lolondola, lodalirika. Ndi ntchito yaluso, yowoneka ngati bizinesi.
