Iyo wunvise 'precision yatakaye ibishashara gushora imari', benshi batekereza ko ari ugukora imiterere itoroshye. Ubwo ni ubuso. Inkuru nyayo iri mukurwanira ubudahemuka buringaniye, urugamba rwo kurwanya kugoreka ibumba ryibumba, no guhora imishyikirano hagati yimyitwarire yumuti hamwe nubushyuhe bwumuriro. Ntabwo ari amarozi; ni urunigi rw'ubwumvikane bugenzurwa.
Umukino wa Shell: Aho Precision Yatsinze cyangwa Yatakaye
Umuntu wese yitaye ku gishashara, kandi byanze bikunze, inshinge nziza niyo ntangiriro. Ariko inyubako ya shell? Nibyo byemeza guceceka. Nabonye amaduka asuka amafaranga mubisobanuro bihanitse bya 3D byacapwe gusa kugirango mbuze ibisobanuro byose byimbere muri kote yambere. Ubucucike bwijimye, ingano ya stucco ingano na morphologie - ibona ibi nabi, kandi uteka kugoreka kuva kumunsi wambere. Igikonoshwa ntabwo ari ifu gusa; ni corset yubatswe mugihe cyo gusuka na bariyeri mugihe cyo gukonja. Niba kwaguka kwinshi kwubushyuhe bidafite aho bihuriye nicyuma cyawe, urimo wirukana umurizo wawe kwihanganira.
Fata umutego uhuriweho: dufate ko igishishwa cyijimye ari cyiza kumurongo uhamye. Kubice biremereye byuma, birashoboka. Ariko kubintu byo mu kirere gifite uruzitiro ruto cyane muri nikel ishingiye kuri superalloy, igikonoshwa kirenze urugero gishobora gutera amarira ashyushye kuko abuza kwikuramo. Ukeneye igikonoshwa gikomeye kugirango ufate icyuma, ariko hamwe na 'gutanga' bihagije mubushyuhe bukwiye. Aho niho sisitemu yihariye ihuza hamwe na stucco ikoreshwa kuva muburambe bwuburambe ikora itandukaniro. Nibyiyumvo nuburambe, ntabwo ari urupapuro rwihariye.
Ndibuka umushinga wamazu ya sensor turbine, aho spec yahamagariye kwihanganira ± 0.1mm kuri bore y'imbere. Ibishashara byari byiza. Twakoresheje ikoti risanzwe rya zirconia. Isuka yambere yahoraga yinjira kuri + 0.15mm. Ikibazo? Ikoti yo mu maso ntiyakiriye neza hamwe na superalloy, irema umubyimba muto-urenze uko byari byitezwe byahinduye neza ubunini bwurwobo. Twahinduye kuri silika yahujwe na primaire yibanze - kutitwara neza, inzitizi nyinshi - hanyuma dusubira mubwihanganirane. Uwiteka neza yatakaye ibishashara gushora imari inzira yuzuyemo micro-imikoranire.
Imyitwarire ya Alloy: Umufatanyabikorwa Utateganijwe
Tuvuze ibinyobwa, aha niho ubumenyi rusange bwananiranye. Gutanga ishoramari neza ya 304 itagira umwanda nisi usibye kubikora hamwe na cobalt ishingiye kuri cobalt nka Stellite 6 cyangwa imwe ishingiye kuri nikel nka Inconel 718. Amazi yabo, ibintu bigabanuka, hamwe no kugumana ubushyuhe biratandukanye cyane. Ntushobora gukoresha filozofiya imwe.
718, nkurugero, ifite urwego runini rwo gukonjesha. Irashaka gukora micro-porosity niba utagenzura icyerekezo gikomeye. Ibi twabyize inzira igoye kumurimo wa moteri ya kare. Ubuso bwiza burangije, bwatsinze X-ray, ariko binanirwa gupima umunaniro. Ikibazo cyitaruye ihuriro ryagaburiwe nabi. Igisubizo nticyari kongeramo ibyuma byinshi (riser nini); byari bijyanye no gusimbuza amarembo kugirango habeho ubushyuhe bugenda butera imbere. Twagombaga gutekereza hafi dusubira inyuma duhereye kumiterere ikomeye kugeza kumazi.
Niyo mpamvu amateka yumushinga afite akamaro. Iduka nka Ikoranabuhanga rya Qingdao Qiangsenyuan (QSY), ivuga imyaka mirongo hamwe na alloys, ntabwo ari urutonde rwibikoresho gusa. Barimo berekana ububiko bwuzuye bwubushyuhe, ubushyuhe mbere yubushyuhe, hamwe na protocole ikonje kuri buri muryango. Urwo rwibutso rwinzego nicyo kibuza ikigeragezo gihenze-no-kwibeshya kumishinga mishya.
Gukora Intoki: As-Cast na Byarangiye
Nta gice na kimwe mubyukuri 'precision' igororotse hanze. Hama hariho amafaranga yo gutunganya. Ubuhanga nyabwo nukugabanya. Intego nugutanga casting itajegajega, hamwe nibibazo bike bisigaye, kugirango iyo ikubise imashini ya CNC, ntabwo igenda itateganijwe nkuko ubicamo.
Nagiye impaka nabashushanya bagaragaza amafaranga y'urwembe-ahantu hose, nka 0.5mm. Ibyo ni fantasy kuri geometrike nyinshi. Ishira igitutu kidashoboka kubikorwa byo gukina kandi akenshi biganisha ku gusiba mugihe cyo gutunganya mugihe igikoresho gisomye gusa hejuru yimutse. Uburyo bufatika nuburyo bukorana: menya ibimenyetso byingenzi bya datum hamwe no gufunga hejuru. Komeza ultra-tight kwihanganira no kurangiza neza kubari murwego rwo gukina (rimwe na rimwe ndetse na net-shusho), kandi wemerere amafaranga menshi cyane kubijwi bitari ngombwa. Aha niho ibikoresho byahurijwe hamwe. Icyitegererezo cya QSY cyo gutanga byombi gushora imari na CNC gutunganya munsi yinzu bisobanura ko ibitekerezo bisubirwamo ari bigufi. Itsinda ryimashini rirashobora kubwira ibishingwe, Hey, turabona ahantu hahamye kuri iyi flange, kandi barashobora kuyisubiza kukibazo cyakonje cyaho.
Twigeze kugira umubiri wa valve aho as-cast-shobuja abayobozi bari murwego rwihariye, ariko mugihe cyo gukanda, igikoresho rimwe na rimwe cyazereraga. Nyirabayazana? Ntabwo ari ukutamenya neza, ariko uduce duto duto duto duto tutari twinshi kuburyo twerekana kuri X-ray ariko twahinduye imbaraga zo guca. Gukosora byari uguhindura ibyago byaho kugirango tunonosore icyerekezo kuri abo bayobozi. Byari igisubizo cya casting kubibazo byo gutunganya.
Imitekerereze ya Tooling: Digital to Physical
Inganda zimuka kuri 3D yacapishijwe ibishashara cyangwa resin ishusho ni impinduramatwara, ariko ntibyumvikana. Nibyiza kuri prototypes hamwe nibintu byimbere byimbere. Kubyara umusaruro, ibikoresho gakondo byifashishwa mu gutera ibishashara biracyari umwami kugirango bihamye kandi birangire. Ingingo ni uguhitamo inzira nziza.
Urudodo rwa sisitemu ni ngombwa, nubwo. Moderi nziza ya CAD ntacyo ivuze niba uwashushanyije ibikoresho atabaze ibintu bigabanuka neza. Kandi ntabwo ari ijanisha rimwe. Ni anisotropique-itandukanye mumashoka atandukanye ashingiye kubice bya geometrie no kubuza kuva mugikonoshwa. Ibishingwe byiza bifashisha ibintu byahinduwe bigabanuka, akenshi biva mumateka yabo bwite kumiterere asa na alloys. Bubaka indishyi mubikoresho kuva bagitangira. Uku gukosora mbere yubusa ni ikimenyetso cyukuri ibishashara byabuze akazi.
Ndibuka gusuzuma gusuzuma uwatanze urukurikirane rw'ibikoresho bya pompe. Icyitegererezo cyumucuruzi umwe cyari gifite isura nziza yindege ariko ikananirwa kugerageza. Twabashushanyije dusanga imyirondoro ya vane yazimye mu buryo bwihishe - icyitegererezo cyari cyapimwe hamwe n'ikintu kimwe cyo kugabanuka. Undi mucuruzi, wakoze akazi nkako mu bihe byashize, yakoresheje ibintu bitandukanye, yongerera ishusho gato mu cyerekezo cya hub hagati. Abakinnyi babo bakinnye bakinnye. Ubwo ni ubumenyi bwihishe.
Ubwiza ninzira, ntabwo ari ubugenzuzi
Hanyuma, ibisobanuro ntabwo bigenzurwa kumpera; yubatswe muri buri ntambwe. Nibidukikije bigenzurwa nicyumba cyibishashara (ubushyuhe, ubushuhe). Nubugenzuzi bwitondewe bwamahuriro mbere yo kurasa. Nibisobanuro byerekeranye no kurasa umurongo wa autoclave ya dewaxing hamwe nitanura ryo gucumura. Gutandukana mubisasu birasa ubushyuhe birashobora guhindura uburyo bwimbaraga nimbaraga zayo, biganisha ku kwibeshya cyangwa igikonjo kumeneka mugihe cyo gusuka.
Ibikorwa bya nyuma ya casting nabyo bifite akamaro. Nigute ushobora gutema ibice ku giti? Uruziga rwangiza rushobora gutera guhangayika na micro-crack niba bidakozwe neza. Kuvura ubushyuhe nubundi bucukuzi. Igisubizo kivura ibintu bigoye kugirango uhindure ibintu bitarinze gutera urupapuro cyangwa igipimo cyangiza cyangiza ubuso nuburinganire bworoshye.
Iyi mitekerereze yuzuye niyo itandukanya abatanga igice nabafatanyabikorwa bakora. Iyo sosiyete ikunda QSY ashimangira imyaka 30 mugukina no gutunganya, ni code yo kuba warabaye muri ibyo bibazo bifitanye isano. Bashobora kuba barabonye uburyo ihinduka ryumusenyi wigikonoshwa rigira ingaruka kumashini, cyangwa uburyo guhindura uburyo bwo kuvura ubushyuhe bushobora gukiza igice cyibice bifite ibipimo bya marginal. Nibintu byukuri-byukuri neza yatakaye ibishashara gushora imari—Umuhengeri, rimwe na rimwe urimo akajagari, burigihe burambuye ubuhanga bwo guhuza impinduka ijana kugirango ukubite urupapuro rumwe, rutababarira. Ntabwo ari ibishashara gusa.
