Precision casting inonziwoInvestment casting. Iyi nzira yekukanda inoderedza kana kuti haicheki panguva yekukanda. Iyo inzira yekukanda ine huwandu hwakasiyana hwekushandisa, yakakwirira dimensional kurongeka kwekukandira, uye yakanakisa yepamusoro mhando. Haisi mu-ultra-high tembiricha mamiriro, uye inonyanya kukodzera kukanda zvikamu mumaindasitiri epamusoro-soro akadai seaerospace uye kudzivirira kwenyika. Yakanga iri yekutanga kushandisa Stainless simbi yekukandira nzira yekukandira mablades eturbine mune yayo inotungamira aero-injini panguva iyoyo. Chigadzirwa chakapedzwa chakarumbidzwa nemativi ose, uye iyi nzira yakakurudzirwa zvikuru. Stainless simbi chaiyo yekukanda tekinoroji muindasitiri yekuvamba, asi yakasiyana neyechinyakare indasitiri yekuvakisa nekuti iyo yakawedzerwa kukoshaprecision kukanda zvigadzirwayakakwirira.
Silica Sol Shell Maitiro
Iyo silica sol shell yekugadzira maitiro inowanzo shandiswa mune yakaomesesa yemukati yekupisa injini zvikamu zvekukanda indasitiri. Iyo yekuputira inoshandiswa mune iyi nzira ine kugadzikana kuri nani, haidi kuomeswa kwemakemikari, inopesana nekupisa kwakanyanya, uye ine nani kuramba deformation. Nekudaro, tekinoroji iyi zvakare ine chimwe chikanganiso ichi, ndiko kuti, kudziya kwewakisi mold ishoma, iyo inogona kuvandudzwa nekuwedzera surfactants, asi ichawedzera mari kune imwe nhanho.
Mvura Glass Shell Process
Iyi nzira yakagadzirwa kare kare. Nyika yedu yakaunzawo tekinoroji iyi kubva kuSoviet Union kuma1950 nema1960. Iyi nzira ine mutengo wakaderera, mashandiro ari nyore, uye yakaderera mbishi zvinhu zvinodiwa. Hunhu hwakakosha hwekuita hunoshandisa parafini-stearic acid yakaderera-yekupisa mold zvinhu, uye binder mukugadzira goko rinoshandisa girazi remvura, iro rinoshandiswa zvakanyanya mukukandira simbi isina tsvina. Nekudaro, dambudziko hombe reiyi nzira kana ichienzaniswa neiyo silica sol goko rekugadzira maitiro nderekuti iyo yepamusoro mhando yeakawanikwa castings ndeyeavhareji uye kurongeka kwedimensional kwakadzikira. Kubva pakaunzwa tekinoroji iyi, kuvandudzwa kukuru kwakaitwa, kunyanya muzvinhu zvinotevera:
1. Kuvandudza shell coating.
Iko kunatsiridza kukuru ndeyekuwedzera imwe huwandu hweivhu refractory kune yekumashure yekunamatira goko, iyo inovandudza zvakanyanya kusimba kwegoko, uye inoona imwe goko kugocha uye kupfura.
2. Optimization of harderer.
Iyo yekuomesa yechinyakare inonyanya kushandisa ammonium chloride, asi chinyorwa ichi chinoburitsa huwandu hukuru hweammonia uye nitrogen oxide gasi panguva yekukanda, izvo zvinosvibisa mhepo. Naizvozvo, aruminiyamu chloride mhinduro inoshandiswa pachinzvimbo, uye aruminiyamu chloride crystal inoshandiswa zvakare. Mhedzisiro yemumiririri yakafanana neyeammonium chloride, asi mumakore achangopfuura, kushandiswa kwe magnesium chloride hardener kune mukana wakakura maererano nekuoma kwekumhanya uye zvakasara, saka ikozvino inonyanya kuda kushandisa magnesium chloride seyakaoma. .
3. Yakaumbwa shell.
Nekuda kwekuti kunaka kwepamusoro kwegoko remvura yegirazi yekuputira kune zvimwe zvirema, akawanda epakutanga zvikamu zvakakandwa muchimiro chemulti-layer mold composite casting, iyo inochengetedza mutengo kune rumwe rutivi uye inovandudza kunaka kwepamusoro kwekukanda kune rumwe rutivi. ruoko.
4. Kuvandudza teknolojia itsva.
Parizvino, maitiro matsva akakura anofanira kunge ari ega-priming casting process, furo plastiki mold, yakanyungudutswa mold shell casting uye mamwe maitiro. Aya maitiro ane mabhenefiti anotungamira mune zvimwe zvinhu, asi kuvandudzwa kweramangwana kucharamba kuchikwezva vashandi vesainzi uye tekinoroji.
Multi-tekinoroji Muchinjika Kushandisa neRapid Prototyping Technology
Dhizaini uye kugadzira mold mukugadzira simbi isina simbi chaiyo yekukanda wax molds yakaoma uye inopedza nguva, asi nekukurumidza prototyping tekinoroji inogona kugadzirisa kukanganisa uku. Iyo yekukurumidza prototyping tekinoroji chete haigone kuitwa nekuda kwekushomeka kwezvinhu, kwakawanda mumakore achangopfuura Kushandiswa kwepolymer tekinoroji kuwana iyo yakatenderedza chimiro chekukanda, uyezve kugadzira wax mold, iyo inoshandiswa muStainless simbi chaiyo yekukanda. Semuyenzaniso, chiedza kurapa matatu-dimensional modelling tekinoroji (SLA) uye yakasarudzika laser sintering tekinoroji (SLS). Aya matekinoroji maviri parizvino akakura matekinoroji anoshandiswa mukubatana nekudyara kukanda. SLA tekinoroji inogona kupa yakakwirira dimensional kurongeka, kunyanya kune zvikamu. Kurongeka kwekunze kwekunze, SLS, kune imwe nhanho, zvigadzirwa zvakachipa zvishoma, asi iko iko kurongeka kune imwe gap kana ichienzaniswa neSLA tekinoroji, iyo yakakodzera kune rimwe basa rekukanda nemutengo unodiwa. Nekudaro, zvichiri kufanira kutarisisa kudzora kusanganisa kwakakosha kwekukurumidza prototyping tekinoroji uye simbi isina tsvina chaiyo yekukanda tekinoroji panguva yekushandiswa, sekutarisisa kwakazara kwekudzora mutengo uye kukanda chaiko kwezvikamu, uye kusarudza iyo yakakodzera chiyero poindi inokurumidza prototyping tekinoroji. uye tekinoroji yekukanda mari. Nyaya inokosha yekubatanidza organic.
Multi-tekinoroji Muchinjika Kushandisa neComputer Technology
Chirongwa chekugadzira uye optimization basa mustainless simbi chaiyo yekukanda maitiro ibasa rinotora basa uye rinotora nguva. Mumakore achangopfuura, nekuenderera mberi kwekuvandudza tekinoroji yekombuta, maindasitiri mazhinji anoda huwandu hukuru hwekuverenga uye kuverengera kwakaringana akaunza basa remakomputa, uye nenzira yakafanana Various calculation softwares yakagadzirwa, seProCAST, AutoCAD, AFSolid, Anycasting uye mamwe software. . Aya masoftware anogona kuverenga kana kutevedzera dhizaini uye kukanda maitiro eStainless simbi chaiyo yekukanda. Iyo yazvino optimization scheme inogona kugadziridzwa nekuverenga data. Kuvandudzwa kwekukandira kwaita basa rakanaka mukusimudzira. Nekudaro, mune yazvino maitiro ekushandisa, isu takaona zvakare kuti isu tinofanirwa kutarisisa kune yekumisikidza kushandiswa kwekombuta software uye iyo thermophysical parameters yezvinhu pachayo. Mhinduro yakanaka kumatambudziko aya inogona kupfupisa zvakanyanya nguva yekusimudzira yesimbi isina tsvina yakakandwa.
