Tarisa, akarasika furo. Ndiyo imwe yeaya maitiro anowana yakawanda buzz yekugona kwayo-pedyo-neti chimiro, yakaoma geometries, yakaderedzwa machining. Asi famba mune gumi nheyo dzinoti dzinozviita, uye unogona kuona gumi kududzira kwakasiyana kwekubudirira. Pfungwa isiriyo huru? Kuti ingori imwe nzira yakachena pane yechinyakare yekukanda jecha. Hazvisizvo. Iyo yakazara sisitimu, uye kana foam yako mapatani, kukoira, jecha compaction, uye geting zvisiri mumutambo wakakwana, usina kusimba, uri kungopisa polystyrene inodhura kugadzira zvimedu. Ndakaona kuyedza kwakakundikana kubva kuvanhu vanobata foam pateni senge inoraswa kwete iyo chaiyo musimboti wekuita.
Iko Kugadzira-kana-Kuputsa Nzvimbo Yekutanga: Iyo Patani pachayo
Zvose zvinoenderana nefoam pattern. Haisi chimiro chete; inobata nzvimbo inoshanduka. Takadzidza izvi nenzira yakaoma kare kare. Kutsvaga yakachipa, yakaderera-density EPS mabhero anogona kuchengetedza mutengo kumberi, asi iyo bead fusion mitsetse inove yekukundikana mapoinzi. Iro furo rinoda kuva gobvu zvakakwana kubata kubata pasina kudonhedza, asi yega yega giremu yekuwedzera ivhoriyamu yegesi panguva yekudira, inokanganisa kuyerera kwesimbi uye kuperera kwekupedzisira. Iyo pateni gungano-gluing akawanda furo zvikamu-ndiyo imwe mhondi yakanyarara. Shandisa chinonamira chisiri icho, uye hachinamati chisungo (chinotungamira kupinda kwesimbi musono, chirema chakashata chinodaidzwa kuti veining) kana kuti chinosiya kabhoni yakasara inogadzira inclusions. Isu takachinjira kune yakasarudzika inopisa-yakanyunguduka inonamira yeakakosha majoini mushure mekunge batch yemiviri yevharuvhu yakaramba ichikundikana pamaflange. Ndiwo maminutiae aya anopatsanura prototype kubva pakugadzira-yakagadzirira mhando.
Ipapo pane kupfekedzwa, iyo refractory slurry. Iyi haisi pendi; ndicho chipingamupinyi uye permeability controller. Yakanyanya kukora, uye gasi rinobva mufuro rinopfungaira harigone kutiza nekukasira, zvichiita kuti simbi imire kana kuvhuvhuta kumashure. Kunyanya kuonda, uye jecha rinoputika, richigadzira hutsinye, hwakasanganiswa pamusoro pekupedzisira. Iyo viscosity inoda kugara ichitariswa - tembiricha uye hunyoro muchitoro zvinoikanganisa zvakanyanya. Isu tinovavarira jira rinooma kune ganda-rakafanana neganda, rakasimba zvakakwana kuti jecha rizadzwe asi rakaputsika zvekutsemuka pasi pesimbi kumberi kuti gasi ribude. Kudzikama kwaunonzwa, chaiko, nekudonha kwazvinoita kubva pachigunwe chako.
Ndinoyeuka rimwe purojekiti yepombi inogarwa nepombi, basa rakaoma romukati mepaseji. Mutengi aida iyo mu ductile iron. Matangiro ekutanga aive nenjodzi — shrinkage porosity yakaungana muzvikamu zvakakora. Iyo furo, hongu, inonyangarika uye inosiya isina inotsanangurwa yekupisa huwandu. Nyaya yaive yekuti geji redu, rakakopwa kubva kujecha nzira, harina kuverengera kurasikirwa kwekupisa kubva pakuora kwefuro rekupedzisira. Taifanira kugadzirisa zvakare hurongwa hwekudyisa zvachose, tichiwedzera mamwe makwikwi munzvimbo dzisiri dzechinyakare kutsiva iyo yekutonhodza maitiro. Yakawedzera machining touch point gare gare, asi zvaive izvo kana zvimedu. Chimiro ndicho chigadzirwa, kusvikira chisipo.
Jecha, Vibration, uye Illusion yeKupusa
Jecha rakaoma, risina kusungwa. Inonzwika nyore. Asi kubatana kwayo kwakatenderedza patani isina kusimba, yakavharwa ndipo panozvarwa hurema hwekuona. Tafura yevibration ndiyo mwoyo wayo. Unoda kuzunguzika kwakawanda-nzira kuti jecha riyerere mugomba rega rega pasina kuburitsa kana kukanganisa patani. Zvakanyanya hutsinye, uye unogona kugera madziro matete patani kana kuita kuti jaketi ritsemuka nguva isati yakwana. Kunyanya kupfava, uye unowana nzvimbo dzakapfava mujecha, zvichiita kuti mold wall ifambe uye kusarongeka kwedimensional — kwatinoti bulging.
Isu tinomhanyisa musanganiswa we silica jecha, kunyangwe kune mamwe magiredhi esimbi isina tsvina takatamira ku zirconia nekuda kwekudzikama kwayo kwepamusoro. Chinokosha kuwirirana. Chero mwando muvengi; inopindirana nesimbi inopisa uye furo rinoora kugadzira homwe dzeutsi, zvichikonzera mapinho. Isu tinoomesa jecha muomesi inotenderera kana paine kanyoro kehunyoro. Iyo inhanho yekuwedzera, asi yakachipa pane yakazara kupisa kubata gare gare kuyedza uye kusimbisa porosity yausingakwanise kana kuona pamusoro.
Kudurura pachayo kunopesana nemamiriro ekunze asi kunonetsa. Uri kudurura simbi pane zvinenge zviri mafuta. Mutengo wakakosha. Kunyanya kunonoka, uye furo rinodzikira mberi kwesimbi kumberi, zvichiita kuti gomba ridonhe kana kuti jecha riwire mukati. Kukurumidza, uye kugadzirwa kwegasi kunokunda kupenya kwependi, zvichikonzera mhirizhonga uye slag inclusions. Iwe unotarisa maburi ehutsi, ruvara uye kubuda kwayo kunokuudza kana kutsva kwakachena. Utsi hutema, hune mafuta hunoreva kupisa kusina kukwana, dambudziko. A akatsiga, greyish-white plume ndizvo zvaunoda. Iyo inzira yekunzwa zvakanyanya.
Painokodzera nePaisingaite
Kurasika furo inopenya kune dzimwe mhuri dzezvikamu. Mabhuroko einjini, misoro yemasilinda, manifolds—maumbirwo akaomarara ane migero yemukati ingada macore ejecha akaoma uye anodhura. Kubviswa kweiyo core assembly uye core prints ndiko kuponesa kukuru mukushanda uye kunovandudza kuenderana kwedimensional. Kukambani yakaita seQingdao Qiangsenyuan Technology Co., Ltd. (QSY), ine makumi emakore mugoko uye kuisa mari, kuwedzera furo rakarasika kune portfolio yaive yekupa maitiro akakodzera eiyo geometry chaiyo. Dzimwe nguva, chikamu chatinotaura chinogona kugadzirwa negoko regoko kana furo rakarasika. Iyo breakpoint inowanzove yemukati yakaoma uye vhoriyamu. Kumhanya kwe500 zvimedu zve hydraulic valve body ine intersecting oiri maberere, furo rakarasika rinokunda. Kwemakumi mashanu ezvimedu zve-high-temp turbine nozzle mune cobalt alloy? Kudzokera kune investment casting.
Kuganhurirwa kwezvinhu ndokwechokwadi. Aluminium uye grey iron ndiyo inonyanya kukanganwira. Ductile iron inoda kudzora kwakasimba kwemazinga e magnesium (kuora kwefuro kunogona kukanganisa nodularization). Simbi uye isina tsvina zvinogoneka, asi kuvhunduka kwekupisa pajasi kwakakwira, uye iyo kabhoni yekumusoro kubva pafuro ndeyechokwadi kunetseka. Takaita akabudirira kumhanya kwe304 mabhuraketi asina tsvina, asi zvaida pekugara pekugara nepamusoro refractoriness uye chaiyo, inokurumidza kudurura. Haisi yekuenda kune yakakwirira-alloy simbi pano; Kukandira kwekudyara kuchiri mambo kune izvo, zvichipihwa hunyanzvi hweQSY ne nickel uye cobalt-based alloys. Iwe unotamba kune simba rekuita.
Post-Process: The Reality Check
Shakeout iri nyore-ingoshandura bhokisi. Asi yekutanga kutarisa pakukanda ndeyechokwadi cheki. Iyo yepamusoro ine hunhu, hushoma hwakakasharara, orenji-peel mameseji kubva pakupfekedza interface. Yakanaka kudarika jecha asi haina kutsetseka semari. Iwe unenge uchigara uchiona chiedza, kabhoni firimu mumashure; kazhinji inoputika muimba yekuchenesa. Kukanganisa kwakasiyana. Jecha rakadonha rinoratidza sekukurumidza, kukanganisa kwakaipisisa. Kupinda kwesimbi kunotaridzika kunge hutsinye, simbi fin pamwe nemusono wepateni. Gasi porosity inonyanya kupararira, kazhinji iri pasi pepamusoro.
Machining ndiko uko kugadzikana kwedimensional kunobhadhara. Pasina musimboti wekuchinja, iyo datum maficha akavimbika. Asi iwe unofanirwa kuziva nezve spongy zone. Dzimwe nguva, ingori mamirimita kana maviri pasi penzvimbo yakakandwa, panogona kuve nechikamu che micro-porosity kubva kune furo decomposition magasi. Haisi inogara yakakanganisika, asi kana uine yakakomba yekuisa chisimbiso kumeso, unotsanangura kushoma machining kucheka kwe2mm kuti upinde pasi payo. Isu takadzidza izvi mushure mekunge batch yecompressor housings yapasa bvunzo yekutanga, asi yakakundikana mumunda mushure mekupfeka kushoma. Mhosva yacho yaiva buri rebhobho panzvimbo yakavharika yaipfeka yakashama. Ikozvino chave chinyorwa chakajairwa pane iyo dhizaini yeakakosha interfaces.
Mifungo Yokupedzisira: Chishandiso, Kwete Chishamiso
Saka, ndizvo kurasika furo ramangwana? Kune zvimwe zvikamu, zvachose. Ndiyo mhinduro yakanaka kumatambudziko chaiwo. Asi chirango chinoda, chinobata-bata. Inopa mubayiro kungwarira uye inoranga kufungidzira. Haisi chinhu chaunongo wedzera pane chinovamba. Inoda sero yakatsaurirwa, kubva pakuumbwa kwepateni kusvika pakubata jecha. Kune akabatanidzwa mutengesi seQSY (unogona kuona kugona kwavo renji pa https://www.tsingtaocnc.com), ndechimwe chishandiso. Iyo inovabvumira kutungamira mutengi - toti, mumwe munhu anoda yakasimba yakakandwa simbi chikamu chine mukati menzira - kune iyo inonyanya kushanda nzira. Dzimwe nguva iro rinorasika furo, dzimwe nguva ndiyo core shell mold process. Kukosha kuri pakuziva mutsauko, muchitoro pasi huchenjeri hwekuti maitiro ega ega anonzwa sei kana achifamba nemazvo, uye zvakanyanya kukosha, kana zvave kuda kukanganisa. Ndicho chinhu hapana bhurocha rinogona kunyatsotora.
