Xa usiva 'isitofu sesinyithi esilulwelo sibumba', iingqondo ezininzi zitsibela ngqo kwi-sci-fi okanye ezo zixhobo zombane ezikumgangatho ophezulu zineebhokisi ezintle, ezingenamthungo. Leyo yinxalenye yayo, ngokuqinisekileyo, kodwa inyani kwii-Foundries kunye neevenkile zoomatshini zigqwesile kakhulu kwaye zininzi kakhulu. Asikokwenza nje into ibonakale ipholile; imalunga nokusombulula ingxaki yejiyometri engakwaziyo ukujongana nesanti, okanye ukuphumeza umphezulu ophelisa iiyure zomsebenzi wepost-CNC. Umbono ongeyiyo oqhelekileyo kukuba yindawo yokumisa enye yokugqibelela. Ngokwesiqhelo, luthethathethwano phakathi koguqulo lolwelo, amazinga okuqina, kunye noqoqosho olukhohlakeleyo lweendleko zezixhobo ngokuchasene nomthamo wenxalenye. Ndikhe ndabona iivenkile zintywila ekucingeni ukuba yinguqulelo ephucukileyo yokubumba inaliti yeplastiki, kuphela ukuba itshiswe-ngokoqobo nangokomfanekiso-ngoxinzelelo lwe-thermal kunye nokuziphatha kwe-alloy ababengayilindelanga.
Umdaniso ongundoqo: i-alloy, i-Mold, kunye nefestile yeThuba
Intliziyo yenkqubo ayingomatshini wokutofa ngokwawo; ngumtshato wezinto ezibonakalayo kunye nokungunda. Awusebenzi ngeepolymers. Ujongene neentsimbi ezisuka kulwelo ziye kuqina kwindawo ebalulekileyo, emxinwa yefestile yobushushu. Ngokomzekelo, kunye ne ialloys esekwe nickel sisoloko sibaleka kwindawo yethu, ubushushu obugqithiseleyo—iqondo lobushushu elingaphezu komlinganiselo weliquidius—yinto yonke. Uphakamileyo kakhulu, kwaye utshabalalisa i-mold yensimbi (i-die) okanye ibangele i-porosity yokunciphisa kakhulu. Iphantsi kakhulu, kwaye ufumana i-misrun okanye i-laps ebandayo ngaphambi kokuba umgodi uzalise. Yinto ebambekayo. Ufunda ukugweba i-viscosity yentsimbi ngendlela egalela ngayo kwi-ladle, ubuchule obungenakufundisa.
Apha kulapho amashumi eminyaka amava omdlalo jikelele, njengemvelaphi yeminyaka engama-30 esinayo Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), iba yinto engenakuxoxisana. Awukwazi ukuthenga nje umatshini kwaye uqale. Udinga loo ngqiqo yendeleyo yendlela iintsapho ezahlukeneyo zesinyithi eziziphatha ngayo. Ukuhamba ukusuka ekujuleni izinto zentsimbi engatyiwayo ukuya kwi-alloy esekwe kwi-cobalt kwisicelo sokunxiba okuphezulu akulotshintsho olulula lwepharamitha kwisikrini se-HMI. Lonke ulawulo olushushu lokufa, uyilo lwenkqubo yokungena, nkqu nearhente yokukhulula, inokufuna ukuphinda kucingelwe. Ukungunda ayisosikhongozeli sokwenziwa; sisitshintshi sobushushu esisebenzayo, kwaye ukuyila imijelo yayo yokupholisa bubugcisa obungaphezulu kunenzululwazi ngamanye amaxesha.
Ndikhumbula iprojekthi ye-impeller eyinkimbinkimbi kwi-duplex yensimbi engenasici. Umxhasi udinga iincakuba ezicekethekileyo, ezithe ngqo emoyeni. Ukuchithwa kwesanti kushiye ukwahluka kakhulu; ukwenziwa kwe-slid kubize kakhulu. Ukubumba inaliti yesinyithi elulwelo wayengumgqatswa onengqondo. Sifumene ijometri ngqo kwishot yokuqala-ukuveliswa kweenkcukacha kwakumangalisa. Kodwa inxalenye yajika ngexesha lokukhutshwa. Ingxaki? Sayila ukupholisa ukuze kuqiniswe ngokufanayo, kodwa besingakhange sichaze ngokugqibeleleyo umahluko wobushushu phakathi kwehabhu eshinyeneyo kunye neencakuba ezibhityileyo. Yayiyimeko yeklasi yokuphumelela idabi lokuzalisa kodwa ukulahlekelwa yimfazwe yoxinzelelo. Siyisombulule ngokongeza ixesha elifutshane, elilawulwayo lokuhlala kwi-die ngaphambi kokukhutshwa, ukuvumela ubushushu ukuba bulingane ngokwaneleyo. Loo tweak yavela kumdibaniso wedatha yokulinganisa kunye nesisu somsebenzisi esivakalelwa kukuba inxalenye yayingekakulungeli ukuphuma.
Umgibe wokuSebenza: Apho iiProjekthi ziphumelele okanye zizinzile
Masithethe ngendlovu egumbini: izixhobo. Ukufa ngenxa ukubumba inaliti yesinyithi elulwelo lutyalo-mali olukhulu. Yenziwe ngoomatshini ukusuka kudidi oluphezulu, intsimbi yokusebenza eshushu, ihlala inemigca yokupholisa entsonkothileyo egrunjiweyo ngaphakathi. Ixesha elikhokelayo lokufa okuntsonkothileyo linokuba ziinyanga. Le yeyona ndawo inkulu yokusilela kwabaqalayo. Bazijongela phantsi iindleko kwaye baqikelele kakhulu ukugqibelela koyilo lokuqala.
Umgaqo osebenzayo esiwulandelayo kukuba singaze sigqibezele uyilo lokufa ngaphandle kokuqalisa iprototype sisebenzisa ixabiso eliphantsi, igraphite eyenziwe ngoomatshini okanye ingxubevange yobhedu. Kulidini, kodwa ityhila imiba yokuhamba, iindawo ezishushu, kunye neengxaki zokukhupha umoya ngeqhezu leendleko. Senze oku kuthotho lwezindlu ezidityanisiweyo kwi-alloy ekhethekileyo, ephezulu yokuqhuba. Imodeli yeCAD yayibukeka igqibelele. Umfanekiso wegraphite wasibonisa indawo efileyo ekoneni apho umoya uvaleleke khona, ubangela isithuba. Ukuyilungisa kwi-CAD ngaphambi kokusika intsimbi yokugqibela yasisindisa impazamo yezibalo ezintandathu kunye nokulibaziseka kweeveki ezili-10.
Ubudlelwane kunye neqela lomatshini le-CNC libalulekile apha. E-QSY, isebe lethu le-CNC langaphakathi aliloqumrhu elahlukileyo; bayinxalenye yencoko yophuhliso ukusukela kusuku lokuqala. Ngabo abasixelela ukuba i-engile eyidrafti iyavezwa, okanye ukuba uyilo oluthile lwephini luzakusinda kwimijikelo eyi-100,000. Oku kudityaniswa phakathi kokuphosa kunye nomatshini yinto ejika inkqubo yokubumba inaliti elungileyo ibe ngumjelo othembekileyo wemveliso. Inxalenye ihlala iphuma kwi-die kufuphi-net-shape, kodwa iindawo ezibaluleke kakhulu zokutywina okanye iintambo ziya kufuna okokugqibela, okuchanekileyo kwe-CNC touch. Ukuyila loo msebenzi wesibini yinxalenye ye-DFM yokuqala (uYilo lokuVeliswa).
IiNuances zeMathiriyeli: Ayinakuze ibe yintsimbi nje
Igama elithi metal elulwelo lilula ngokukhohlisa. Kwindawo yethu, kunokuthetha umgangatho we-316 ongenasici, umxube we-cobalt-chrome ongaguqukiyo, okanye i-alloy ye-nickel ephezulu yokushisa. Ngamnye unobuntu bakhe ngexesha lokutofa. I-Aluminiyam kunye ne-zinc alloys, eziqhelekileyo kwi-low-temperature die-casting, zixolela ngokufanelekileyo. Xa ungena kwi ialloys ezikhethekileyo—abo benza iinxalenye zemichiza, i-aerospace, okanye izixhobo zonyango—imithetho iyatshintsha.
Thatha i-alloys esekwe nickel. Ziyathandeka kumhlwa kunye nokuxhathisa ubushushu, kodwa ziqhelene nokwahlulwa kunye nokukrazuka okushushu ukuba umphambili wokuqina awulawulwanga ngobunono. Awunakuvele uqhumise ukungunda ngento epholileyo; kufuneka ukhokele ukuqiniswa ukusuka kwindawo ekude kakhulu emva kwesango, ngokuyimfuneko ukuhambisa i-microstructure yesinyithi kwindawo. Oku kuhlala kuthetha ukufudumeza ngobuchule iindawo ezithile zediyizi, hayi nje ukuyipholisa. I-counter-intuitive. Utofa isinyithi esinyibilikisiweyo, kodwa unokuba neekhatriji zokufudumeza kumzimba wokufa ukuthintela ukubanda kwangaphambi kwexesha kwicandelo elibalulekileyo.
Oku sikufunde kabuhlungu ngecandelo levalvu. Isixhobo sasigqibelele kwimeko yerhasi emuncu eyayiza kusebenza kuyo. Kodwa phantsi kovavanyo loxinzelelo, ayiphumelelanga kwindawo ebonakala ngathi ayinakwenzeka. Uhlalutyo lwe-metallurgical lubonise ukukrazula okuncinci kumda wengqolowa-inyembezi eshushu. Ulungiso aluzange lutshintshe i-alloy; yayiyila ngokutsha isango kwaye iphuphuma kakhulu ukudala ukuthambeka kobushushu obulungileyo ngalo mzuzu wokugqibela wokuqina. I ukubumba inaliti yesinyithi elulwelo inkqubo kwafuneka ukuba ithungwe hayi nje ukubumba inxalenye, kodwa ukwakha imfezeko yayo yangaphakathi.
Ukuqukumbela ukuya ekugqityweni: I-CNC Handshake
Umsebenzi awuwenziwa xa inxalenye ikhutshiwe kwaye i-sprue inqunyulwe. Kulapho ixabiso lomnikezeli wenkonzo epheleleyo lingenakuphikiswa. Inxalenye eyenziwe nge ukubumba inaliti yesinyithi elulwelo ihlala inesibonelelo esincinci sesitokhwe-mhlawumbi yi-0.5mm okanye ngaphantsi kwiimpawu ezibalulekileyo. Oku kufuna ukuchaneka kungekuphela nje ekubumbeni, kodwa kulungiso lomatshini olulandelayo lwe-CNC. Inxalenye kufuneka ifunyanwe kwaye icinezelwe ngokubhekisele kwii- as-cast datum, hayi imodeli yethiyori yeCAD.
Iqela lethu lomatshini liphuhlisa izilungiso zesiko ngokusekwe kwiingxelo zokuhlolwa kwenqaku lokuqala ukusuka kwiindawo ezibunjiweyo. Bajonge ezona mpawu zihambelanayo, ezingabalulekanga ukuba bazisebenzise njengeendawo zokubambelela. Umzekelo, sinokusebenzisa umphathi othile owenziwe ngokuthembekileyo kwishothi nganye njengeyona ndawo iphambili ye-Z-axis. Esi sandla singenamthungo sisuka kumgangatho wesiseko ukuya kwivenkile ye-CNC, phantsi kophahla olunye njengase-QSY, sisusa umdlalo onetyala kunye neempazamo zolungelelwaniso ezithwaxa imisebenzi yangaphandle. Umchwephesha uyayazi i-quirks yenkqubo yokuphosa, kwaye injineli yokubumba iyayazi into efunwa ngumatshini ukuze anyamezele.
Olu manyano lubalulekile kuqoqosho lwelinge lilonke. Iindleko eziphezulu zangaphambili ze ukubumba inaliti yesinyithi elulwelo isixhobo silungelelaniswa ngokuncitshiswa kwexesha lomatshini kunye nenkcitho yezinto eziphathekayo inxalenye nganye. Ukuba inxalenye ebunjiweyo ayihambelani, ulahlekelwa yinzuzo ngokukhawuleza ngenxa yokuba inkqubo ye-CNC kufuneka iphendule ngokuguquguquka okusendle, ukongeza ixesha lokujikeleza kunye nokugqoka isixhobo. Inkqubo yokubumba elawulwa ngokuqinileyo yenza into eqikelelwayo, ekufutshane-netha-imilo engenanto ukuba i-CNC inokugqiba ngokukhawuleza nangokuthembekileyo. Leyo yi-synergy eyenza iteknoloji isebenze kwimveliso yevolumu ephakathi ukuya phezulu yezinto ezinzima.
Isigwebo sehlabathi lokwenyani: Sisetyenziswa nini, sihamba nini
Ke, emva kwayo yonke le nto, iyenzeka nini ukubumba inaliti yesinyithi elulwelo iyavakala? Ayisosisombululo sehlabathi. Ikhanya xa unenxalenye eneepaseji ezintsonkothileyo zangaphakathi, iindonga ezibhityileyo kakhulu (ezantsi ukuya kuthi ga kwi-1mm ene-alloys ezithile), iimfuno ezigqwesileyo zokugqiba umphezulu (njengoko amaxabiso eRa anokuba aphantsi kakhulu), kunye nemfuno yezinto eziphathekayo ezibonelela ngeentsimbi ezikhethekileyo kuphela. Umthamo ungundoqo-udinga inani elaneleyo lonyaka ukuze uhlawule eso sixhobo sotyalo-mali ngaphezu kwamawaka eeshoti, hayi amakhulu.
Ndicebise abathengi ngokuchasene nayo xa inxalenye yabo yayisisibiyeli esilula, okanye xa iivolumu zabo eziqikelelweyo zazingcangcazela. Ukuba bhetyebhetye kokwenziwa kokungunda kweqokobhe okanye utyalo-mali, ngokunjalo ubuchule bethu obungundoqo, ibiyinto engcono ngokwezemali. Isilingo sokusebenzisa inkqubo ephucukileyo sinamandla, kodwa isigwebo sobuchule simalunga nokukhetha isixhobo esifanelekileyo, hayi esona sikhulu kakhulu.
Ekugqibeleni, impumelelo ukubumba inaliti yesinyithi elulwelo ngumsebenzi onzulu. Ihlala ekudibaneni kwesinyithi, uyilo lomatshini, ubunjineli be-thermal, kunye nokuhanjiswa kwemveliso. Kumalunga nokuqonda ukuba intsimbi inenkumbulo yendlela eyazalwa ngayo—itofwe, yacudiswa, yaqiniswa phantsi koxinzelelo. Ukuyilungisa kuvakala kuncinci njengoloyiso lwemveliso kwaye kufana nokwenza uthethathethwano ngempumelelo phakathi kwemithetho yefiziksi kunye neemfuno zeplani. Kwaye nantso into oyifundayo kuphela ngokuma ecaleni kweziko, ukuva ubushushu, nokubukela ukuhamba kwesinyithi.
