Iwe unoona 'yakarasika wax simbi yekukanda' pane imwe pepa uye funga 'chaizvo, zvimiro zvakaomarara, kupera kwakanaka' - uye hauna kukanganisa. Asi ndiyo shanduro yebhurocha. Pazvinowanikwa chaizvo, uye kutaura chokwadi panogumburwa vatengesi vemazuva ese, iri mukuturikirwa kubva patani yakanaka yewakisi kuenda kune inoshanda, inonzwika simbi yakagadzirira kushandiswa. Mukaha uripo pakati pekukanda uye kukanda kwakanaka ndiko uko makumi emakore ezvitoro-pasi maawa ane basa.
Wakisi Ndiwo Mavambo, Kwete Magumo
Munhu wese anotarisa pane wakisi. Ndiwo unyanzvi hunoonekwa. Asi mutongo chaiwo unotanga mushure mekudonhedza waxi, kana wasara uine goko receramic goko. Ndiyo nzvimbo isina kunaka. Kuzadza kwaunoita kunotsanangura zvese. Kudira simbi hakuna kufanana nekuzadza bhaketi; chiitiko chinodziya chinodzorwa. Nesimbi, kunyanya alloys akakwirira, hwindo pakati pekuzadza kwakachena uye chikanganiso chakamanikana. Ndakaona kudirana uko tembiricha yakadzimwa nechinhu chaiita sechinhu chidiki - pamwe 25°C - uye zvakaunza mhirizhonga yakakonzera mavanga epamusoro zvekuti hapana kugaya kwaigona kudzima. Iyo mold inogona kunge yakakwana, asi maitiro akange asina.
Apa ndipo panoratidza kurangwa kwemuvambi. Nzvimbo yakadai Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) haingomhanyi mutsara; vave vari paizvi kwemakore anopfuura makumi matatu. Hupenyu hurefu ihwohwo hunotaura nezvemaitiro ane hunyanzvi. Zvinoreva kuti vangangoona nzira dzekutadza - goko rinotsemuka kubva mukupisa nekukurumidza, izvo zvinosanganisirwa kubva kune slag, iyo micro-porosity kubva gasi. Kunyanya kwavo mu Investment casting uye shell mold process haisi bullet point; iraibhurari yezvikanganiso zvakagadziriswa. Iwe haugone kunyepera kudzika ikoko.
Tora gating uye riser dhizaini. Haisi dzidziso. Kune muviri wakaoma wevharuvhu watakamboita mu316 isina tsvina, yekutanga simulation yaitaridzika zvakanaka. Asi kudira kwekutanga kwairatidza kuderera padanho rakakora-kusvika-mutete. Kugadzirisa kwanga kusiri kungowedzera simbi yakawanda (simukira); yakanga ichiisa patsva magedhi kuti adzore nzira yekusimbisa. Taifanira kushandisa zvakare muti wewakisi. Ndiyo yarasika nguva nemari. Chitoro chisina iyo grit yekugadzirisa dambudziko yaizongoramba ichitumira zvikamu zvinogamuchirika, uye mutengi anobata nekutadza kumberi pasi pemutsara.
Material Kupfuura Nhamba Yegiredhi
Kudoma kabhoni simbi kana Stainless simbi ndiko kutanga, asi zvine njodzi kujeka. Mukati me 'stainless,' une austenitic mazana matatu akatevedzana, iyo martensitic mazana mana akatevedzana, duplex mamakisi - imwe neimwe inoita zvakasiyana zvakasiyana panguva uye mushure mekukandwa. Mvura yavo, kuderera, uye simba rinopisa zvinosiyana. Dururira 304 seunodurura 17-4 PH, uye unenge uchitsemuka. Iyo post-cast kupisa kurapwa kwakakosha kune vamwe, haina basa kune vamwe.
QSY's listed material range - kubva ku iron iron and standard steels kusvika kune nickel-based and cobalt-based alloys - anondiudza kuti vanonzwisisa simbi haisi yepadivi. Aya alloys akakosha imhuka. Ivo vanowanzodirwa sevhisi yakanyanyisa: turbine blades, makemikari reactor zvikamu. Dzinodhura, saka zvimedu zvinorwadza. Kukandira kwavo kunoda kuchengetedzwa kwemhepo inert, chaiyo yekudzora kupisa, kazhinji vacuum kunyungudika. Iwe haungopindiri mune izvi. Kana webhusaiti yavo, tsngtaocnc.com, inoratidza kugona mune izvi, inoreva mwero wechoto tekinoroji uye nzira yekudzora inovaparadzanisa kubva kune yebasa-shop caster.
Ndinoyeuka chirongwa chinosanganisira Monel (nickel-copper) alloy component. Wakisi nedeko zvakanga zvisina chikanganiso. Kudira kwaitaridza kunaka. Asi panguva yekugogodza kwegoko, takawana yakakura kuita kwepamusoro - rudzi rwe crusty, oxidized layer. Nyaya yacho? Kemisitiri yegoko rebhainda raive netsvina shoma yaiita zvehasha nenickel yakanyungudutswa patembiricha yepamusoro iyoyo. Isu takachinjira kune imwe yakasiyana, yakawanda inert refractory coating yezvikamu zvekutanga. Dambudziko rakagadziriswa, asi chete nekuti isu taive nerutsigiro rwesimbi rwekuiongorora. Chitoro chinongoita carbon steel chingadai charasika zvachose.
Iyo Finish inogadzirwa muRough
Imwe pfungwa isiriyo yakajairika: wakisi yakarasika inogadzira chikamu chakagadzirira kushandisa. Kashoma chokwadi. Chainogadzira chikamu chine yakanaka as-cast surface, kazhinji yakatenderedza 125 Ra microinches kana zvirinani. Asi 'yakagadzirira' zvinoenderana nekushandisa. Ibhuraketi rekushongedza here? Pamwe girazi rakareruka bhedhi blast rinokwana. Ndiyo hydraulic manifold block? Iye zvino iwe unoda chaiyo yekuisa chisimbiso nzvimbo, yakarukwa madoko, maburi ekukwira. Ndiko kwakabatanidzwa CNC machining kugona kunova kusingagone kutaurirana.
Iyi ndiyo synergy iyo yakazara-sevhisi inopa. QSY kubatanidza kukanda uye machining pasi pedenga rimwe chinhu chikuru chekugadzirisa uye kunaka mukana. Ivo vanogona kugadzira iyo yekukanda vaine machining stock mupfungwa, vachinzwisisa kuti chikamu chichagadziriswa sei, pane datum mapoinzi. Ivo vanoikanda, kupisa kuibata (kana zvichidikanwa), wozoigadzira munzvimbo imwechete. Izvi zvinotonga cheni yese. Ndakasangana nedambudziko rekutumira mazambiringa kune imwe shopu yemuchina yakaparadzana, ndokuzongowana kakanganisika kadiki kana jecha rakavanzika rinopaza chishandiso panguva yekuchera. The blame game inotanga. Imba yakabatanidzwa ndiyo ine maitiro ese.
Kugadzirwa kwesimbi yakakandwa, kunyanya kubva ku wakisi yakarasika process, ine zvayo zvayo. Izvo zvinhu zvinogona kuve nekuoma kwakasiyana mavara kana kutonhora kwanga kusiri yunifomu. Akanaka machinist, achishanda pamwe neiyo foundry timu, anogona kugadzirisa mafaera uye kumhanya. Vanogovana ruzivo. Iyo yemukati mhinduro loop haionekwe kune mutengi asi yakakosha pakuenderana.
Apo Zvakaoma Zvinosangana Nekushanda
Chiratidziro chemhando yepamusoro chewakisi yakarasika ndiyo yakashongedzwa, jira-rakafanana geometry. Uye inokunda ipapo. Asi bvunzo dzakaomarara chikamu chinotaridzika chakapfava asi chakavanzika chakaoma. Funga nezvepombi yepombi ine mavane matete, akakombama uye akafukidzwa nedhizaini. Inoda mukati ma hydraulic surfaces ayo akatsetseka kuti aderedze mhirizhonga. Inoda kuenzanisa. Kugadzira izvi kubva pakasimba kungave kupambadza, akawanda-axis marathon. Kuikanda ndiyo sarudzo ine musoro.
Asi heino rub: iwo mavane matete anofanirwa kuzadza nesimbi yakanyungudutswa pasina kutonhora nguva isati yakwana, izvo zvinogadzira kutonhora kunovhara (yakafanana-yakafanana chirema). Vanofanirawo kuva nesimba rakakwana rekutsungirira simba re centrifugal uye cavitation erosion mubasa. Apa ndipo panosangana patani dhizaini, gating sainzi, uye sarudzo yealloy. Iwe unogona kusarudza 17-4 PH isina tsvina yekukandira kwayo uye kunotevera kuoma kwemvura, ichikupa inodiwa simba-ku-huremu reshiyo.
Isu takafananidza chikamu chakafanana kamwe chete. Chekutanga iteation, mavanes aive nemaminetsi akapetwa. Hazvionekwi neziso, asi zvinoratidzwa nedhayi penetrant inspection. Dambudziko rakanga riri kumhanya kwesimbi. Isu takazvigadzirisa nekugadzirisa kudira mukombe kureba kuti uwedzere kudzvanywa musoro, kumanikidza yakawedzera laminar kuzadza. Yakanga iri chinjo yakavanzika ine muuyo unoshamisa. Izvi hazvisi mubhuku chero ripi zvaro; ndiyo mhando yemaitiro intuition yakavakwa kubva kumazana ekudira akafanana.
Chiyero Chaicho: Kuenderana Pasi Pekumanikidzwa
Pakupedzisira, munhu wose anogona kugadzira imwe yakanaka kukanda. Chiratidzo chechivako chakafanana nechakatsanangurwa chiri kuita kuti chiuru chifanane nechokutanga. Izvi ndezvekutonga kwemaitiro, kwete hunyanzvi. Iri nezve zvakanyorwa kunyunguduka maitiro, nguva yekuomesa goko, kudira matanda, uye nekuongorora kwakasimba - yekutanga-chinyorwa, mu-kuita, uye yekupedzisira.
Kushanda kwavo kwemakore makumi matatu kunoratidza kuti vakagadzira masisitimu eizvi. Zvinoreva kuti vanogona kubata iyo dhizaini yekumhanyisa yevharuvhu akateedzana kana mutsara wemidziyo yekuvhiya, kwete kungoita imwe chete. The shell mold casting hunyanzvi hwavanotaura hunozadzisa Investment casting; dzimwe nguva chikamu chisina kuoma kunzwisisa asi chakakura chinokodzera zvirinani kune resin-shell process. Kuziva kuti ndeipi nzira yekukurudzira chikamu chekubvunzana yakanaka foundry inopa.
Saka pandinofunga kurasika wakisi simbi kukanda, Ndinofunga zvishoma zvewakisi uye yakawanda yemhirizhonga inodzorwa yekudira, iyo metallurgical discipline, uye handoff isina musono kusvika pakupedza. Icheni. Simba rechikamu chekupedzisira rakangonaka chete sechinhu chisina kusimba chetani iyoyo. Chigadzirwa chaicho hachisi chimiro chesimbi chete; irwo ruzivo rwakadzamirwa rwakaita kuti ive nechokwadi kuti yagadzirwa.
