Anthu ambiri akamva za 'precision casting foundry' amajambula zitsulo zopanda chilema, zonyezimira zomwe zili m'kabukuka. Ndilo lingaliro lolakwika loyamba. Zoona zake ndi zambiri zokhudzana ndi kulolerana molamulidwa - kuyang'anira kutentha, kupsinjika maganizo, ndi khalidwe lakuthupi m'njira yomwe imakufikitsani pafupi ndi zomwezo momwe mungathere pamalonda. Simatsenga; ndi kugawikana kwa ndondomeko ulamuliro.
Masewera a Zipolopolo: Zoposa Mchenga Wokha
Tengani chipolopolo cha nkhungu. Dzinali limapangitsa kuti limveke losavuta, monga kuviika pateni mumchenga ndi guluu. Koma mdierekezi ali mu ceramic slurry kapangidwe ndi kagawidwe mchenga wa stucco. Pezani kukhuthala kolakwika ndi masekondi pang'ono pa kapu ya Zahn, ndipo makulidwe a chipolopolo chanu amakhala osagwirizana. Ndawonapo magulu omwe mbali imodzi ya chipolopoloyo inali yangwiro, ina inaphwanyidwa panthawi ya dewaxing chifukwa chovala choyambirira sichinagwirizane bwino. Ndi luso logwira mtima-mumaphunzira kuweruza slurry ndi momwe imatsikira, osati ndi pepala lokha.
Apa ndipamene mbiri yakale yogwira ntchito imakhala yofunika. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zoposa 30 pakupanga ndi kupanga makina, mwachiwonekere yapserera kupyola zikwi zambiri za slurry formulations. Mwina akhazikika pamgwirizano womwe umapangitsa kusintha kwa chinyezi ku Qingdao, komwe kumatha kuwononga nthawi yowumitsa. Simumapeza izi kuchokera kusitolo yatsopano.
Mayeso enieni ali ndi ma cores ovuta. Panjira yozizirira mkati mwa ma valve, pachimake pamafunika kupirira kupanikizika kwachitsulo koma kumasokonekera kuti achotsedwe. Nthawi ina tinkagwiritsa ntchito mchenga wa silika pa ntchito yachitsulo chosapanga dzimbiri. Chitsulocho chinalowa pakati, ndikupanga chisokonezo chomwe chinatenga masiku a EDM kuti athetse. Kukonza? Kusintha kwa mchenga wa zircon kusakaniza kwa kutsika kwake kwa kutentha. Kusintha kwazinthu zazing'ono, mtengo waukulu wa salvage umapewa.
Kuponya Ndalama: Sera ndi Kudikirira
Investment casting ndi chithunzi cha mwana cholondola, koma msampha wake waukulu ndi nthawi. Chigoba chilichonse cha ceramic chimayenera kuuma bwino. Ithamangitseni, ndipo mumamva kuphulika kwa nthunzi panthawi yothira-yotchedwa 'kuphulika kwa chipolopolo' - kukusiyani ndi nkhungu yodzaza ndi zitsulo ndi zidutswa za ceramic. Nthawi yozungulira ndi bwana, osati wokonzekera.
Kusonkhana kwa sera ndi luso lina. Kwa gulu la masamba a turbine, kuwotcherera kwa zipata za sera kumachitidwa ndi manja. Wogwiritsa ntchito chida chotentha agwira sera; kutentha kwambiri, ndipo kumasungunula nsonga yopyapyala ya tsambalo; kuzizira kwambiri, ndipo kuwotcherera kumakhala kofooka, zomwe zimapangitsa kuti pateni zisamangidwe panthawi yomanga zipolopolo. Ndi luso lomwe limatenga zaka. Ndikukumbukira ndikuyendera malo osungiramo phula kumene wowotchera phula wabwino kwambiri amatha kupanga mtengo wazithunzi 72 mu theka la nthawi ya ganyu yatsopano, osapanganso ziro. Kuchita bwino kumeneko kumasulira mwachindunji kulolera.
De-waxing ndi sitepe yovuta, yomwe nthawi zambiri imanyalanyazidwa. Njira yakale inali kuwombera ng'anjo, zomwe zimapangitsa kuti zipolopolo ziwonongeke. Tsopano, zoyambira zapamwamba kwambiri, kuphatikiza zomwe zidaphatikizidwa CNC makina monga QSY, gwiritsani ntchito ma autoclaves othamanga kwambiri. Chinyengo ndicho kupindika-kutentha kwapakati. Iyenera kusungunula sera kuchokera mkati popanda kuchititsa mantha a kutentha. Webusaiti yawo, tsngtaocnc.com, imatchula ntchito yawo yopangidwa ndi faifi tambala. Ma alloys awa nthawi zambiri amakhala ndi zofunikira zolimba zamapangidwe ambewu, kutanthauza kuti kutentha kwa nkhungu kumayenera kukhala kolondola. Phokoso lolakwika la de-wax lomwe limang'amba chipolopolo limatha kulowetsa chitsulo, kuwononga kumapeto kwake ndikupangitsa makina opangira positiyi kukhala owopsa.
Zinthu ndi Chilamulo
Simungathe kuyankhula za a mwatsatanetsatane kuponyera maziko popanda kulowa mozama muzitsulo. Chitsulo cha carbon, chosapanga - amachita mosiyana. Koma ma alloys apadera ndi pomwe ukatswiri weniweni umayesedwa. Tengani ma aloyi opangidwa ndi cobalt, monga Stellite. Amatsanuliridwa pa kutentha kwambiri ndipo amakhala ndi chizolowezi choyipa kupanga magawo olimba, osasunthika ngati atakhazikika molakwika.
Tinali ndi pulojekiti yopangira mphete yosindikizira yosamva kuvala. Kusindikizaku kumafuna kulimba kwa Rockwell C. Kuthira koyamba, pogwiritsa ntchito njira yozizira yokhazikika, kunali kofewa kwambiri kapena kosweka. Nkhani inali ya kutentha kwa nkhungu. Tinayenera kupanga mbale zoziziritsa kukhosi - zoyika zamkuwa zomwe zimayikidwa mu nkhungu - kuti chitsulocho chikhale cholimba, ndikuchikakamiza kuti chizizire kuchokera pagawo lofunikira kupita kunja. Zinagwira ntchito, koma zinawonjezera masiku awiri ku nthawi yopanga nkhungu. Uku ndiye kusinthanitsa kosalekeza: kulondola ndi mtengo poyerekeza ndi nthawi yotsogolera.
Apa ndipamene mbiri ya zinthu za wogulitsa ili yofunika. Zomwe kampani ikunena kuti imagwira ntchito ndi ma aloyi opangidwa ndi faifi ndi chinthu chimodzi, koma kukhala ndi chipika chothira bwino pazigawo zomwe zili m'malo ankhanza (ganizirani zopopera zamakina) ndi zina. Zimatanthawuza kuti athetsa mavuto olowera ndi kukwera kosiyana ndi ma shrinkage a alloys.
CNC: Kumene Kuponya Kumakumana Ndi Zowona
Palibe gawo loyimba lomwe lilidi 'lofanana ndiukonde' m'njira yolondola kwambiri. Ndiko komwe kumaphatikizidwa CNC makina zimakhala zosakambitsirana. Ubwino waukulu wopezeka ndi makina am'nyumba ndi mayankho. Pamene makina amabowola mu kuponyera ndikupeza malo olimba kapena pore yapansi panthaka, chidziwitsocho chimabwereranso ku gulu losungunuka.
Ndikukumbukira gulu la mabakiteriya achitsulo. Anapanga makina mokongola kupatula ngodya imodzi kumbali iliyonse yomwe chidacho chimayankhula. Kunakhala kusinthasintha pang'ono kwa kuzizira kozizira mu ngodya imeneyo ya nkhungu, kupanga malo okhazikika a pearlite apamwamba. Gulu la foundry linasintha zipsepse zoziziritsa pa nkhungu, ndipo vutolo lidatha. Popanda machining pansi pa denga lomwelo, kuzungulira kwa mayankho kumatenga milungu ingapo.
Kwa olimba ngati QSY, kupereka zonse zoponya ndi makina kumatanthauza kuti amatha kuwongolera datum. Atha kuyika mapepala opeza kapena katundu wowonjezera m'malo enieni akudziwa momwe CNC yawo idzagwirire ndikudula gawolo. Synergy iyi ndiyofunikira kwambiri pama geometries ovuta pomwe zololeza makina amayenera kukhala ochepa koma ofananira bwino kuti asadulire khoma.
Zolephera Zimene Zimaphunzitsa
Nthawi zophunzitsira kwambiri zimachokera ku zinthu zomwe sizikuyenda bwino. Poyambirira, tinali ndi chidaliro kwambiri pa pulogalamu yoyeserera yolimba. Tinayendetsa kayeseleledwe ka nyumba ya valve yamkuwa, ndipo imasonyeza kudyetsa bwino. Ma castes enieniwo anali ndi ming'alu yakuya kwambiri mu flange yokhuthala. Kayeseleledwe kameneka sikunapangitse kusinthika pang'ono kwa ma alloy athu enieni amafuta. Tinataya gulu. Kodi tikuphunzirapo chiyani? Kuyerekeza ndi kalozera, osati mneneri. Muyenerabe kudula kuponya kwa nkhani yoyamba, kuyigawa, kuyimitsa, ndikuyang'ana njere. Palibe m'malo mwa kuyesa kowononga.
Kulephera kwina kofala ndikukulitsa njirayo. Nthawi ina tinayesa kukhazikitsa ultra-high-purity argon purge kusungunula chitsulo chosapanga dzimbiri kuti tichepetse kuphatikizidwa. Zinagwira ntchito, koma kuwonjezeka kwa mtengo kunali 300%. Gawolo silinali kusowa; muyezo degassing anali wokwanira. Zomwe zidalipo zinali za pampu yamafuta ambiri, osati gawo lazamlengalenga. Kudziwa nthawi yomwe 'yabwino mokwanira' ili 'yangwiro' pakugwiritsa ntchito ndi lingaliro laukadaulo lomwe limalekanitsa maziko odziwa zambiri kuchokera kumalingaliro.
Choncho, zimene odalirika mwatsatanetsatane kuponyera maziko zikuwoneka ngati? Siyo yomwe ili ndi kabuku kowoneka bwino kwambiri. Ndilo lomwe lingafotokoze, mwatsatanetsatane, chifukwa chake amagwiritsa ntchito kutentha kwina kwa 17-4PH zosapanga dzimbiri, kapena momwe amapangira mitengo yawo ya sera kuti achepetse chipwirikiti cha aluminiyamu. Ndi yomwe tsamba lake, monga la QSY, limalemba molunjika maluso ake -chipolopolo nkhungu kuponyera, kuponya ndalama, makina, ndi mndandanda wazinthu zina-popanda zonenedweratu. Ikuwonetsa kuyang'ana pa kubwerezabwereza pa zozizwitsa. Mu malonda awa, ndiko kulondola kokha komwe kuli kofunikira.
