Kana vanhu vakanzwa simbi yakanyungudutswa, kazhinji vanofananidzira kudururwa kunoshamisa kwesimbi yakanyungudutswa. Chokwadi chakanyanya kuipa uye chine nuanced. Iyo nzira inotsanangurwa zvakanyanya nekutadza kwakanyarara-iyo misrun, kutonhora kuvharika, kubatanidzwa kwaunowana chete mushure mekugadzira-sekukandwa kwakabudirira. Ndapedza makore ndichitenderedza nheyo, ndaona mukaha uripo pakati pemadhizaini ezvinyorwa uye iyo soot-yakasvibiswa chokwadi. Izvi hazvisi zvedzidziso yakakwana; ndezvekutonga kupisa, kemisitiri, uye zana rekuchinja kuti coax simbi kuita anobatsira chimiro.
Kutanga neMould: Kupfuura Kungoita Cavity
Zvose zvinoenderana ne mold. Ita zvisizvo, uye urikungodira simbi inodhura mugomba retsvina rakanaka. Kune yakaoma, yakakwirira-kutendeseka zvikamu, iyo indasitiri inowanzorerekera kune Investment casting kana shell mold casting. Sarudzo haina kungopokana. Ini ndinorangarira batch yedzimba dzepombi kwataishandisa ganda rekuumba kupedzisa kwayo kwepamusoro uye kugadzikana kwedimensional, asi taifanira kuve nehutsinye nedhizaini yekugezera kudzivirira mhirizhonga. Iyo mold haisi chigadziko chinongogara; ndiye maneja wekupisa uye geometry enforcer.
Investment casting, iyo 'yakarasika wax' maitiro, ndechimwe chikara. Iwo mameseji aunokwanisa kuwana anoshamisa - funga turbine mablades ane emukati ekutonhodza nzira. Asi chimiro chewakisi pachacho imhizha. Kana tembiricha yejekiseni yewakisi ichidzimwa nemadhigirii mashoma, unounza kushushikana kusinga ratidzike kusvika ganda re ceramic radzingwa, zvichitungamira kune inodhura goko rakatsemuka. Iketani yezvinotsamira. Kambani yakaita seQingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakumi matatu emakore munzvimbo ino, ingangove yakapisa nezviuru zvemapatani ewakisi kuti idhaye mumaparamita iwayo emhando dzakasiyana-siyana. Ndirwo ruzivo rwemasangano iwe haugone Google.
Zvadaro pane kupindirana kwezvinhu zvekuumbwa. Kudira simbi isina tsvina mu silica sand mold? Unogona kuwana chimiro chakanaka, asi pamusoro pacho chinenge chakashata, chinoda kupinda. Kune mamakisi epamusoro, unoda zircon jecha kana ceramic yakatarisana. Ndiyo imwe yeavo mutengo-vs-kuita maverengero anoitika pasi. Iyo mold sarudzo inoraira zvakananga iyo post-casting basa rekuita. Nzvimbo isina kunaka yekuumbwa inoreva kuwedzera kukuya, nguva yakawanda yekugadzira, yakawanda yekudya mumucheto wako.
Kudurura: Apo Fizikisi Inotora
Ino ndiyo nguva yechokwadi. Alloy tembiricha yakakosha, asi haisi yekungorova nhamba pane pyrometer. Iko kune 'tembiricha yepombi' kubva muchoto uye 'kudurura tembiricha' muforoma. Kudonha kunokosha, kunyanya kune zvikamu zvitete. Ndakaona kudira cobalt-based alloys uko hwindo rakatetepa zvisingaite-kunyanya kupisa uye iwe unobvisa mold, kutonhora zvakanyanya uye simbi haizadzi iyo yakaoma kunzwisisa. Iwe unokudziridza pfungwa yayo, nzira inoyerera nayo simbi uye kupenya kwayo kwepamusoro.
Kugedhe nekusimuka igamba risingaimbwe (kana villain). Hazvisi zvekungopinza simbi mukati; ndezvekudyisa iyo solidification shrinkage. Chikanganiso chekirasi rookie kuisa siiri painotaridzika zvakanaka asi haigadziri nzira yekusimbisa. Zvakaguma nei? Shrinkage porosity yakadzika mukati mekukanda, chirema chinogona kungozviratidza pasi peX-ray kana panguva yekuedzwa kwekumanikidza. Takadzidza izvi nenzira yakaoma pamutumbi wevharuvhu wakakandirwa mu duplex simbi isina tsvina. Yakanaka kunze, asi mutengi wepressure test yakundikana. Kusimuka kwacho kwaive kudiki, kure kure. Kurasikirwa zvachose kwezvinhu uye nguva yekugadzira.
Mhepo panguva yekudurura ndeimwe nhanho. Kune mamwe maalloys, senge mamwe nickel-based, kunyangwe kuratidzwa zvishoma kune okisijeni asi yakanyungudutswa inogona kutungamira kune dambudziko okisijeni. Ndipo panopinda nharaunda dzakadzorwa kana mhepo dzekudzivirira. Icho chinyararire, chinowanzo furatirwa ruzivo runopatsanura dhizaini yekukandira kubva kune yepamusoro-soro.
Material ndeye Zvese (Uye Hapana Pasina Maitiro)
Unogona kutsanangura giredhi rakakwana re simbi yakakandwa kana 316 simbi isina tsvina, asi maitiro emugadziri anosarudza zvaunowana. Melt chemistry control yakakosha. Chinhu chakareruka senge magnesium inopera mu ductile iron inogona kushandura yakasimba, nodular iron kuita isina kusimba, inoputika chimiro kana ukabata ladle refu. Unoda nekukurumidza, yakavimbika spectrograph kuongororwa pasi chaipo.
Kushanda ne special alloys senge nickel kana cobalt-based mhuri isangano rakasiyana. Vanowanzo vacuum yakanyungudutswa kana kugadziridzwa nekutarisira kwakanyanya kudzora kuteedzera zvinhu. Mutengo wezvakagadzirwa wakakwira zvekuti kukanda kwakaraswa ndiko kurova kukuru. Muganho wemhosho unodzikira kuita chero chinhu. Aya alloys anosarudzirwa nzvimbo dzakanyanyisa-tembiricha yakakwira, corrosion yakakura-saka chero hurema hwemukati hunogona kukanganisa. Maitiro ekukanda aya haasi kungoumba; iMetallurgical utariri.
Apa ndipo panoratidza kurarama kwenguva refu kwea foundry. Kambani yave ichishanda kweanopfuura makore makumi matatu, seQSY, ingangove yakadurura makomo esimbi uye yakasangana nekukanganisa kwese kusinganzwisisike mubhuku. Chiitiko ichocho chinoturikira zvakananga kuita zvigadziriso zvemhuri dzakasiyana dzezvinhu, ingave iri ferrite-austenite chiyero mune yakakandwa duplex isina tsvina kana kugoverwa kwecarbide mune cobalt alloy. Iwe unogona kuwana maitiro avo kune izvi zvinyorwa zvakatsanangurwa pane yavo saiti pa https://www.tsingtaocnc.com.
Zvinozoitika: Kucheneswa, Kuedzwa, uye Kutarisana Nechokwadi
Kana kukanda kwatonhora, kuongororwa kwechokwadi kunotanga. Kuzungunusa, kugura masuwo nezvikwiriso—ibasa routsinye. Asi pano, iwe unowana yako yekutanga kutarisa chaiko. Kuiswa kwejecha, misodzi yepamusoro, kukanganisa kwakajeka. Zviri ura-cheki. Kusina-kuparadza kuyedzwa (NDT) ishamwari yako pano. Dhayi inopinda mukati mekuputika kwepamusoro, kuongorora radiographic yemukati ma voids. Yese maitiro ekukanda ane akajairika chirema masiginicha. Mukudyara kwekudyara, zvingave zvimedu zvegoko; mukukanda jecha, inogona kunge iri jecha inclusions.
Ini ndinorangarira batch yekudyara-kukanda zvikamu zveindasitiri yezvekudya uko dhayi inopinda yairamba ichiratidza mitsetse isina kusimba. Yakanga isiri mitswe, asi 'veining' kubva mugomba receramic. Yaive nyaya yecosmetic yaisakanganisa basa, asi spec yeclient yaive yakasimba. Isu taifanira kugadzirisa ganda slurry kuumbwa - tweak kune refractory hupfu particle size kugovera - kuibvisa. Ndiyo nhanho iyoyo yeruzivo rwakanyanya.
Uchapupu hunowanzo mukugadzira. Ndiye mutongi wekupedzisira. Iwe unogona kunge uine yekukanda inopfuura yese NDT, asi kana CNC chishandiso chemuchina charova nzvimbo yakaoma - nzvimbo yakatonhora kana kusanganisirwa kusingatarisirwe - chikamu chose chinogona kunge chisina. Ichi ndicho chikonzero zvivako zvakabatanidzwa zvinobata zvose kukanda simbi uye CNC machining vane mukana. Mhinduro yemhinduro ipfupi. Iwo machinists anogona kutaurira iyo inowanikwa chaizvo izvo zvavari kuona, uye zvigadziriso zvinogona kuitwa pakupisa kunotevera. Inoputsa rusvingo pakati pekukanda nekupedzisa.
Nei Zvose Zvichiuya Pakudzokororwa uye Kuvimba
Iwe haugone kukanda simbi kubva mubhuku rekushandisa. Iwe unodzidza kubva kumadziva ezvimedu zvakaomeswa. Chese chikamu chitsva geometry, yega yega alloy giredhi, ipuzzle nyowani. Nyaya yekutanga kashoma kuti ikwane. Pane kutenderera kweiyo prototype, ongorora, gadzirisa gating, tweak yekudira temp, uye edza zvakare. Iyi yekudzokorora, dzimwe nguva inoshungurudza, maitiro ndiwo musimboti webasa rekutanga.
Ndicho chikonzero kushandira pamwe nefoundry kusiri kungotenga sevhisi; iri kutenga yavo yakaunganidzwa kuedza uye kukanganisa. Kana kambani ichinyora portfolio yemaitiro-shell mold, investment casting, machining-uye zvinhu zvakasiyana-siyana kubva kusimbi yakakandwa kusvika kune alloys akakosha, hazvisi kungonyora masevhisi. Vari kuratidza kugona kufambisa iyi yese yakaoma cheni. Zviri zvekuva neruzivo rwemetallurgical yekusarudza maitiro akakodzera ezvinyorwa uye mashandisirwo, uye hunyanzvi hunoshanda hwekuzviita nguva dzose.
Mukupedzisira, yakabudirira kukanda simbi musanganiswa wezvakadzama zvinhu sainzi uye maoko-pamusoro, anenge intuitive, shopu pasi kudzidzira. Ndezvekuremekedza fizikisi, kudzidza kubva mukukanganisa kwese, uye kunzwisisa kuti mold, simbi, uye nzira yakabatana zvisingaite. Chinangwa hachisi chekudururwa kwakakwana nguva dzese — ingori fungidziro — asi inodzorwa, inofanotaurwa maitiro apo zvinosiyana zvinonzwisiswa uye zvinogadziriswa. Ndizvo zvinoshandura pfungwa muCAD file kuita yakavimbika, inoshanda simbi chikamu.
