Xa usiva 'inkampani yokuphosa echanekileyo', umfanekiso okhawulezileyo uhlala uyindawo ecocekileyo ekhupha iintsimbi ezigqibeleleyo, ezibenyezelayo. Leyo yiglosi yentengiso. Inyani, ukugaya imihla ngemihla, luthethathethwano oluqhubekayo phakathi kwejometri efanelekileyo kwimodeli yeCAD kunye nefiziksi enenkani yesinyithi esinyibilikisiweyo. Akukhona nje ukunyamezelana okuqinileyo; imalunga nokulawula yonke i-ikhosistim-ukusuka kwipatheni yewax ukuya kwinxalenye egqityiweyo yomatshini-usazi ukuba ukutenxa nge-0.1mm kwinqanaba lokuqala kunokuphumela kwinxalenye yenkunkuma emva kweeyure ezingama-30 zomsebenzi. Abathengi abaninzi, kwaye ngokungafihlisiyo abanye abatsha kurhwebo, badibanisa ukuchaneka kunye nobunzima. Bacinga ukuba uyilo oluntsonkothileyo lulingana nokuchaneka okuphezulu. Akunjalo. Ngamanye amaxesha, iblade ye-iturbine ekhangeleka ilula enejeyometri yejeometri yokupholisa yangaphakathi kulapho uvavanyo lokwenyani lulele khona, ngaphezulu kakhulu kunesibiyeli esibonakalayo sokuhombisa esintsonkothileyo.
Undoqo: Yinkqubo yenkqubo, hayi inyathelo elinye
Entliziyweni yayo, yinyani inkampani yokuphosa echanekileyo ichazwa ngokulawula kwayo phezu kwetyathanga. Thatha ukubunjwa kweqokobhe kunye nokuphosa imali-ehlala isetyenziswa ngokutshintshisanayo ngabantu bangaphandle, kodwa zizilo ezahlukeneyo. Ukuphoswa kotyalo-mali (i-wax elahlekileyo) ikunika umphezulu ogqwesileyo wokugqiba kunye nobunzima, obulungele izinto ezinjengee-impellers okanye izixhobo zotyando. Ukubumba iqokobhe kukhawuleza kwimitsi emikhulu yentsimbi engantsonkothanga kancinci okanye iinxalenye zentsimbi. Ukhetho alukho malunga nokuba yeyiphi 'engcono,' kodwa yeyiphi ephilileyo ngokwezoqoqosho nangobuchule bomsebenzi. Ndizibonile iiprojekthi zisilela ngenxa yokuba esi sigqibo senziwe ngokusekelwe kwixabiso leyunithi yodwa, kungahoywa ixabiso lilonke lomatshini owenziwe ngasemva. Ugcina iipeni kwi-casting, emva koko uchithe iidola kwi-CNC ukuyicoca.
Apha kulapho kudityaniswa khona. Ivenkile eyenza kuphela izinto zokugalela kunye nefama ngaphandle komatshini liphupha elibi lolungelelaniso. Ibenchmarks ezinobungakanani ziyalahleka kuguqulo. Yiyo loo nto iimpahla ezithe zahlala, njengeQingdao Qiangsenyuan Technology (QSY), zakha imodeli yazo malunga nezindlu zombini phantsi kophahla olunye. Iminyaka engamashumi amathathu kulo mdlalo, njengoko isingeniso sabo sisitsho, asingobudala nje; imalunga nokusinda kwimijikelo ngokulawula ngaphezulu kwezinto eziguquguqukayo. Badwelisa iqokobhe lokungunda, utyalo mali, kunye nomatshini we-CNC kunye ngesizathu. Kukuhamba komsebenzi. Ugalela inxalenye, uyiyeke ipholile, uyimatshini kwii-mills zakho, uyayihlola ngokuchasene neprogram yokuqala. I-loop yempendulo iqinile.
Uluhlu lwezinto eziphathekayo ngomnye ukuxelela. Intsimbi, intsimbi, intlawulo esemgangathweni. Kodwa xa ubona i-cobalt-based kunye ne-nickel-based alloys echazwe ngokucacileyo, oko kuthetha kwinqanaba elithile lomsebenzi. Ezi ayizizo ukwenza izixhobo zokuhombisa. Ezi zenzelwe i-aerospace, i-high-temp industrial, okanye i-oyile & negesi izinto apho iipropathi zezinto eziphathekayo zibaluleke kakhulu njengemilinganiselo. Ukusebenza ngezi akuko malunga neziko ezishushu; imalunga nokwazi indlela abacutheka ngayo ngokwahlukileyo, indlela abasabela ngayo kwizixhobo zokusika. I-miscalculation kwi-shrinkage allowance ye-nickel-based superalloy inokuguqula i-block ye-5,000 yeedola ibe yi-paperweight ebiza kakhulu.
UMtyholi kwiiNkcukacha: Apho iiProjekthi zihamba kakuhle okanye zingalunganga
Makhe sithethe ngenyani, nangona ixhaphakile, intloko ebuhlungu: ukuguquguquka kobunzima bodonga. Umyili uzoba indlu entle eneendonga ezicekethekileyo ezihlangana neflange eshinyeneyo. Ijongeka kakuhle kwiscreen. Kwi-Foundry, eso sisimemo se-shrinkage porosity okanye iinyembezi ezishushu. Isinyithi siqina ngemilinganiselo eyahlukeneyo. I inkampani yokuphosa echanekileyo umsebenzi wobunjineli kukubamba oku, ukucebisa iifilthi ezifihlakeleyo okanye utshintsho oluthe chu umyili anokungaluthatheli ngqalelo. Luthethathethwano. Ngamanye amaxesha uyaphumelela, ngamanye amaxesha kufuneka uqhube isampuli kwaye uvumele i-X-ray ibonise isiphene ukubonisa inqaku. Iwebhusayithi i-tsingtaocnc.com inokufumana ezi fayile zeCAD yonke imihla. Inyathelo lokuqala ayikokucaphula; luphononongo lokwenziwa kwezinto oluva ngakumbi njengeseshoni yonyango yoyilo.
Enye inkcukacha kukungena kunye nokukhupha umoya. Apho ugalela khona isinyithi kwaye ukhuphe umoya ubonakala ungabalulekanga. Yinto enye kodwa. Ndikhumbula ibhetshi yemizimba yevalvu yentsimbi ehlala ibonakalisa umngxuma womphezulu. Imilinganiselo emihle, ukugqiba okugqibeleleyo, ngaphandle kwale mibhobho mincinci. Sileqe yonke into-umgangatho wesihluzi se-ceramic, ukufudumeza komngundo. Kwafumaniseka ukuba umoya wokungena wawungasebenzi kakuhle kwelo candelo lithile lejometri, ebangela isiphithiphithi esibambe irhasi. Ukulungelelaniswa kwe-2mm kumjelo we-vent, into engabonakaliyo kwinxalenye yokugqibela, isombulule. Le asiyonto yeencwadi; lulwazi lwezizwe olwakhiwe ngokugrumba kunye nokufunda.
Emva kokusasazwa, inqanaba lomatshini le-CNC kulapho 'ukuchaneka' kugqitywe khona. Kodwa nantsi i-nuance: i-machining datum. Ukusaswa akuyobhloko egqibeleleyo. Ke, ngaba uyawumatshini umphezulu wereferensi kuqala kwaye emva koko ulungise kwakhona? Okanye ngaba uyila ukungunda ukubandakanya iilugi zokuphosa ezisebenza njengeedatha zomatshini? Le yokugqibela intle ngakumbi kodwa ifuna ukubona kwangaphambili okumangalisayo kunye nentsebenziswano phakathi kwamaqela adlalayo kunye neCNC ukusuka kusuku lokuqala. Inkampani eyenza zombini ngaphakathi endlwini, njenge-QSY, inokumisela le nkqubo. Inciphisa ixesha lokucwangcisa kunye neempazamo zokupakisha. Awuqeli nje inxalenye; wenza indawo owazi umnombo wayo ngokusondeleyo kuba uwenze ngewax nesanti.
IiMathiriyeli aziluKhetho nje kwiMenyu yokuLahla
Ukukhetha izinto ezivela kwikhathalogu kulula. Ukuqonda into eyenzayo kwinkqubo yakho ethile ngumsebenzi wobugcisa. 17-4 PH engenasici, umzekelo. Amandla amakhulu, ukuxhathisa ukubola. Kodwa unyango lwayo lobushushu (H900, H1150) luchaphazela kakhulu ubugcisa kunye nemilinganiselo yokugqibela. Ukuba wenza utyalo-mali, kuya kufuneka ucwangcise ukukhula / ukushwabana kunyango lobushushu emva kokuthotywa kokuqala. Ngokusisiseko uqikelela ukugqwetheka kabini. Yifumane ingalunganga, kwaye indawo yakho echanekileyo iphumile kwi-spec emva komjikelo wokugqibela we-oveni. Apha kulapho iminyaka engama-30 yamava ingengomgca ofuphukuphuku kwintshayelelo yenkampani; yidatabase yemisebenzi edlulileyo, yintoni esebenzayo kwaye yintoni engazange isebenze ngealloyi nganye phantsi kweejometri ezithile.
Emva koko kukho uqoqosho lwezinto eziphathekayo. Iialloys ezikhethekileyo ezifana ne-cobalt okanye i-nickel-based based zibiza kakhulu. Iindleko ezilahliweyo ziyintlekele. Oku kunyanzelisa i-mindset eyahlukileyo kwi inkampani yokuphosa echanekileyo. Inyathelo ngalinye lenziwa ngabom ngakumbi, uvavanyo luhlala lukhona, uvavanyo olungonakalisi njengedayi yokungena okanye ukuskena kwe-CT kuba lixabiso elifanelekileyo, hayi ubunewunewu. Itshintsha isingqi somgangatho wevenkile. Uxinzelelo lwahlukile. Awuqhubeki umsebenzi onevolumu ephezulu; walusa amacandelo ambalwa exabiso eliphezulu ngokusebenzisa indawo yemigodi yeziphene ezinokwenzeka.
UMlinganiselo wokwenyani: Ukungaguquguquki, Hayi nje Ukuphuma nje kubekanye
Nabani na unokufumana ithamsanqa kwaye avelise indawo enye egqibeleleyo. Uphawu lwevenkile ethembekileyo kukuhambelana kwi-batch runs, kunye nonyaka emva konyaka. Oku kubilisa kulawulo lwenkqubo. Ngaba iqondo lobushushu lokutofa ngewax liyahambelana? Ngaba i-ceramic slurry viscosity ihlolwe kwishedyuli engqongqo? Ngaba izixhobo ze-CNC zibekwe esweni ukunxiba, ngakumbi xa usika ezo zinto zilukhuni? Iyadika, izinto zenkqubo. Ikwayinto eyahlula iingcali kwii-hobbyists.
Ndicinga ngeprojekthi yomenzi wempompo. Babefuna amakhulu aliqela ezinto ezikwaziyo ukumelana nomhlwa. Amanqaku okuqala ayengenasiphako. Malunga neyunithi ye-150, saqala ukubona utshintsho olufihlakeleyo kwiprofayili yeblade. Akwanelanga ukusilela ukuhlola, kodwa umkhwa. Oyena nobangela? Ukunxiba kancinci kwidayizi esetyenziselwa ukutofa iipateni zewax. Ipateni yayitshintsha phantse ngokungaqondakaliyo, eyayiphindaphinda kwiqokobhe leceramic nakwintsimbi. Siyibambile kuba besilandela umkhondo wedatha yezibalo, hayi ukujonga ngokuchasene ne-go/no-go gauge. Elo licala elingafunekiyo lokuchaneka: iitshathi zolawulo lwenkqubo yamanani kunye namagcisa aphaphileyo.
Oku kuhambelana yinto eyakha igama. Iwebhusayithi yenkampani, njengaleyo ye-QSY, inokudwelisa zonke izakhono, kodwa ubungqina bukwi-odolo eziphindayo. Xa umxhasi kwicandelo lamandla ekuthumelela uyilo olutsha lweinjini yeinjini yomoya ngenxa yokuba i-500 yokugqibela oyenzele yona ibinokusilela ebaleni elingu0, obo bubungqina bokwenyani. Kuthetha ukuba ikhonkco lenkqubo yakho libanjwe phantsi koxinzelelo, ngokoqobo nangokomfanekiso.
Ukukhangela Phambili: Ukucudisa kunye neSakhono
Uxinzelelo inkampani yokuphosa echanekileyo imisebenzi ihlala iphindwe kabini: ukunyamezelana okungqongqo kubathengi kunye nemida emincinci evela kubakhuphisana. Imveliso eyongeziweyo (ushicilelo lwe-3D) luhlala lukhankanywa njengesoyikiso, kwaye kwiprototyping ethile ekhawulezileyo, kunjalo. Kodwa ekuqhubeni ukuveliswa kweengxenye zetsimbi ezisebenza kakhulu, ngakumbi kwii-alloys ezikhethekileyo, ukuphosa kusekho inzuzo kwiipropati eziphathekayo kunye neyunithi yezoqoqosho kwimiqulu ethile. Ikamva, ndiyakrokra, likumxube. Ukusebenzisa ushicilelo lwe-3D ukwenza i-ceramic cores engenakwenzeka yokufaka utyalo-mali, umzekelo, ukudala iipaseji zangaphakathi ebezingenakubunjwa ngaphambili.
Omnye umceli mngeni luphuhliso lwabantu. Izakhono ezilapha-ukwenza ipateni, uyilo lwe-gating, i-metallurgy, inkqubo ye-CNC yeenxalenye eziphosiweyo-zizodwa. Bafunda phantsi, ecaleni kweziko kunye nomatshini, kungekhona nje kwigumbi lokufundela. 'Ngaphezu kwama-30 eminyaka' yokusebenza kwefemu asiyombali yoshishino kuphela; lulwazi oluqukiweyo lweenjineli eziphezulu kunye neenkosi ezisisiseko. Iqhinga lidlulisela oko kwixesha apho abantu abatsha abambalwa bajonga isiseko njengomsebenzi. I-software ye-CAD / CAM ephezulu kakhulu isadinga ukuba isigwebo somntu siyixelele, Olu kulinganisa lubukeka luhle, kodwa lusekelwe kumsebenzi ofanayo wonyaka ophelileyo, kufuneka songeze i-0.5% ngaphezulu isibonelelo sokunciphisa apha.
Ngoko ke, xa uvavanya iqabane lokuphosa elichanekileyo, jonga ngaphaya kweenxalenye zencwadana emenyezelayo. Buza ngonxibelelwano lwenkqubo yabo. Buza ukuba baluphatha njani uyilo olunengxaki yokutshintsha kobunzima. Buza umzekelo wokungaphumeleli okunxulumene nezinto eziphathekayo kunye noko bakufundileyo. Iimpendulo zabo, i-nuance kunye namabali emfazwe, aya kukuxelela ngakumbi malunga nobuchule babo bokwenyani kunalo naliphi na ibango lentengiso elikhazimlisiweyo. Injongo asikokugqibelela ephepheni; kuqikelelwa, kuthenjwa, kwaye kuphunyezwe ngobukrelekrele, kugqitywe ngepragmatism ephumelele nzima.
