Xa usiva 'i-air set casting sandcasting', umfanekiso ongoko nangoko ukholisa ukuba lolunye uhlobo lwesanti, mhlawumbi lucoceke kancinci. Leyo yimbono yokuqala ephosakeleyo. Ayisiyonto nje yokusebenzisa umoya ukunyanga isibophelelo. Eyona ncam yokwenyani, kwaye ngokungafihlisiyo apho iivenkile ezininzi ziyakhubeka, kukudibaniso phakathi kokuphinda kusebenze kwakhona komxube wesanti, ukufuma kwendawo kumgangatho wevenkile ngaloo mini, kunye nesibophelelo esikhethekileyo sexesha le-catalyst. Yinkqubo eziva ixolile ide ingabi njalo.
I-Core Mechanism kunye nokuSila kwayo kwemihla ngemihla
Umgaqo uqondile: i-synthetic resin binder ixutywe nesanti eyomileyo ye-silica, kwaye i-catalyst ye-liquid iyaziswa ukuqala inkqubo yokunyanga. Igama elithi 'iseti yomoya' livela kwinto yokuba iphilisa kwiqondo lobushushu begumbi xa igasi. Kodwa nantsi into yokubambisa-ixesha lomsebenzi, okanye 'ubomi bebhentshi', bunobuntununtunu. Ehlotyeni, ngokufuma okuphezulu, umxube wakho unokuqalisa ukuseta kwimizuzu emi-4 ukuba mcaba, ujike ibhetshi egqibeleleyo ibe sisigaqa, ubunzima obungasebenzisekiyo phambi kokuba ide ifikelele kwiflaski yokungunda. Ukomisa kwasebusika kunokolula elo xesha, umngcipheko wokubumba obuthathaka ukuba ukhawuleza ukuhluba ipateni. Uhlala uhlengahlengisa ireyishini ye-catalyst ngokuziva kunye namava, hayi nje kwiphepha ledatha.
Oku sikufunde kabuhlungu kwindlela yokuqhuba izindlu zempompo zomthengi. I-spec ibize ukugqitywa komphezulu ocolekileyo kwiindlela zamanzi zangaphakathi, ukwenza isethi yomoya ukugalela isanti ukhetho olufanelekileyo ngaphezu kwesanti eluhlaza yendabuko. Usuku lokuqala lwahamba kakuhle. Ngosuku lwesibini, kwangena indawo engaphambili, ukufuma kwenyuka, kwaye asizange sihlawule. Isiphumo? Uluhlu lokungunda olunemigangatho ethambileyo, evuthulukayo egqithiselwe ngqo kwisamente. Ngamnye kubo wayeyinto embi. Iindleko zazingekho kwintsimbi kuphela; ibikwixesha elilahlekileyo kunye nokuhlenga-hlengiswa kwakhona komgca wemveliso.
Kulapho ubuchule bokwenene bulele khona. Yinkqubo ebambekayo. Umbumbi ovuthiweyo uya kubamba intlama yesanti exutyiweyo, ayicudise, kwaye agwebe ukuqala kokunyanga ngobushushu obuveliswayo kunye nendlela ophuka ngayo. Akukho sixhobo sinokuthatha indawo yaso ngesantya emgangathweni. I-advanteji, xa uyibethelela, kukuchaneka okungaqhelekanga komgangatho kunye nokugqitywa komphezulu okuhlala kufuna ukucwangciswa okuncinci, okuyi-godsend yeejometri ezinzima.
Ukuhambelana kwezinto kunye ne-QSY's Niche
Le nkqubo ayisiyiyo yonke isinyithi. Ibengezela ngee-alloys ezithanda ukusabela kwegesi okanye zifuna i-gradients ezichanekileyo ze-thermal. Sibe nempumelelo enkulu ngentsimbi edityanisiweyo kunye neentsimbi ezinealloyi ephantsi. Isanti eyomileyo, ebotshelelwe kwiikhemikhali inciphisa ukuveliswa kwerhasi ukusuka kumanzi, inciphisa iziphene zepinholing. Nangona kunjalo, kwiintsimbi ze-chromium eziphezulu okanye ii-superalloys, umdlalo uyatshintsha. Ukugcinwa kobushushu bomngundo kwahlukile, kwaye ukuqhekeka kwe-binder ngamanye amaxesha kunokukhokelela kwi-carburization yomphezulu ukuba awulumkanga malunga nokwakheka kwesanti.
Oku kudibana ngokuthe ngqo nobuchule be-Foundry efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngeminyaka yabo engamashumi amathathu ekujuleni nasekusebenzeni, bayaqonda ukuba le nkqubo isisiqingatha sedabi. Inkampani efana ne-QSY, edwelisa ukubumba iqokobhe, ukuphosa utyalo-mali, kunye nokusebenza ngee-alloys ezikhethekileyo ezifana ne-nickel-based, iya kusondela. isethi yomoya ukugalela isanti ngokuqonda okucacileyo kwemida kunye nentsebenziswano. Umzekelo, umzimba wevalvu entsonkothileyo okwintsimbi ephindwe kabini inokuqala njengesanti eseti yomoya ukulungiselela ukudityaniswa kwayo okungundoqo kunye nokumila kwayo okuphambili, emva koko baye kwiivenkile zabo ze-CNC ukuze bajongane ngokuchanekileyo nokudinwa kunye neflange. Inkqubo yokusetha umoya ibanika i-close-net-shape kunye nokunyaniseka okulungileyo, ukunciphisa inkunkuma ye-alloy ebiza kakhulu ngexesha lomatshini.
Ndikhumbula iprojekthi yokufakelwa komgangatho waselwandle apho imathiriyeli yayiyi-alloy yenickel-copper echaziweyo. Isanti eluhlaza ibiphumile ngenxa yeenkxalabo zokufuma. Ukwenziwa kotyalo-mali kuye kwagqithisa kwaye kubiza ubungakanani benxalenye. Iseti yomoya yayiyeyona ndawo iphakathi. Isitshixo sasiphuhlisa isanti ejongene nesiko-umxube osekelwe kwi-zirconia-ngokuchasene nomzekelo wokuthintela ukusebenzisana kwesinyithi, ngelixa usebenzisa i-silica eqhelekileyo kwisanti exhasayo. Yayiyindlela exutyiweyo eyenzelwe umsebenzi oguquguqukayo.
Umthwalo Womenzi Wemizekelo
Le nkqubo ayinanceba kumgangatho wepateni. Nayiphi na i-undercut, nayiphi na i-backdraft encinci onokuthi uhambe nayo kwisanti eluhlaza, iya kutshixa ipateni kwisingundo somoya. I-resin bond yomelele. Sisebenzisa ii-engile zokuyila eziziva zigqithise kwiliso le-machinist-kaninzi i-3 degrees ubuncinane kwindawo ethe nkqo. Imathiriyeli yepateni nayo ibalulekile. Ukhuni lunokujika kunye nokusabela kwe-exothermic yeresin ephilisayo ngokuhamba kwexesha. Sitshintshele kwi-high-density polyurethane okanye iipateni zetsimbi kuyo nayiphi na imveliso ehamba ngaphezu kwamaqhekeza angama-50. Iindleko zokuqala ziphezulu, kodwa ukuhambelana kunye nokunciphisa ixesha lokunciphisa ipateni yokulungisa intlawulo yayo.
Ukukhupha umoya kobunye ubugcisa obuchuliweyo. Umngundo womelele. Awunakuthembela ekungeneni kwesanti kuphela ukuze uvumele iigesi zibaleke ngexesha lokugalelwa. Songeza iitshaneli ezicacileyo ezikrolwe kumphezulu wokwahlulahlula okanye sebenzisa iwax ye-vent kwipatheni etshayo. Ukufumana oku kungalunganga kukhokelela kwimitruns okanye ukudumba kwemilinganiselo yokuphosa, iziphene ezifumaneka kuphela kuhlolo lokugqibela.
INyaniso yezoQoqosho kunye nokuKhethwa kweNkqubo
Ngoko uyikhetha nini? Asiyonto emiselweyo. Kwizinto ezilula, ezinomthamo ophezulu wentsimbi engwevu, isanti eluhlaza iyakhawuleza kwaye inexabiso eliphantsi. Kwizacholo ezintsonkothileyo okanye iiblade zeinjini, uya kutyalomali. Umoya owenziwe ngesanti ithatha indawo ephakathi ebalulekileyo: ubungakanani obuphantsi ukuya obuphakathi bamalungu afuna isiphelo esingcono kunye nokunyamezela kunesanti eluhlaza, kodwa makhulu kakhulu okanye alula ngokwejometri ukuthethelela indlela yotyalo-mali epheleleyo. Cinga izibiyeli ze-injini, iimeko zegiya, imizimba yevalvu emikhulu, okanye ihardware yezakhiwo.
Ubalo lwezoqoqosho lubandakanya iindleko ze-binder, ezibaluleke kakhulu, kodwa zinciphisa ngokucutha igumbi lomsebenzi wokucoca kunye nezibonelelo eziphantsi zomatshini. Ukugcinwa kwe-2mm yesitokhwe macala onke kwi-100kg yentsimbi yokuphosa iguqulela kwiiyure ezincinci kwiziko lokusila. Kumenzi odibeneyo onjenge-QSY, le mbono epheleleyo-ukusuka kwi-Foundry ukuya kwinxalenye egqityiweyo yomatshini-apho ixabiso lokwenene lenkqubo libanjwe. Ibavumela ukuba bacaphule ngokukhuphisanayo kwicandelo eligqityiweyo, hayi nje ukuphosa okukrwada.
I-takeway? Sisixhobo sengcali. Ifuna intlonipho yekhemistri kunye nezinto zokusingqongileyo. Ayinakuxolela ukungakhathaleli. Kodwa xa isetyenziswe kwindawo efanelekileyo, kunye nenkxaso efanelekileyo ukusuka kwipatheni yokwenza ukuya kwi-post-casting operations, ivelisa iziphumo ekunzima ukuzibetha. Imalunga nokufaka inkqubo kumjikelo wobomi bemveliso, hayi ukunyanzela imveliso ibe yinkqubo eqhelekileyo. Nguwo lowo umgwebo ovela ekuboneni impumelelo yayo eqaqambileyo kunye nokusilela kwayo okubizayo, okuxabisa kakhulu kwivenkile.
