Uva 'i-wax elahlekileyo yesiko' kwaye ngoko nangoko ucinge ngobucwebe obuntsonkothileyo okanye ezo ziqwenga zobugcisa ezineenkcukacha. Ngumgibe oqhelekileyo lowo. Kwicandelo loshishino, ngakumbi apho ndichithe iminyaka, lirhamncwa elahlukileyo ngokupheleleyo. Incinci malunga ne-aesthetics-kuqala kwaye ngaphezulu malunga nokusombulula ingxaki apho kungekho nxalenye ye-shelf ikhona. Inxalenye 'yesiko' ayibobunewunewu; yimfuneko. Kuthetha ukuba uhlala ujongana necandelo ekufuneka uphile kubushushu obugqithisileyo, ukubola okungapheliyo, okanye uxinzelelo oluhlekisayo lomatshini. Ipatheni ye-wax sisiqalo nje sencoko ende kakhulu, ephithizelayo phakathi kwenjongo yoyilo kunye nenyani ye-metallurgical.
Iqokobhe loMba: AyisiyoMngundo nje
Uninzi lweenkcazo zitsiba ngqo ukusuka kwiwax ukuya kwintsimbi. Batsiba esona sigaba sibalulekileyo, sobushushu: ukwakha iqokobhe leceramic. Kulapho uphumelela khona okanye uphulukane nomsebenzi. Asithi nkxu nje umthi wewax eludaka; Siyinjineli iqokobhe elinokumelana ne-1500 ° C+ yentsimbi enyibilikisiweyo ngaphandle kokuqhekeka, ukuhexa, okanye ukusabela ngentsimbi. Kwindawo efana ne-QSY, ngamashumi amathathu eminyaka kubumba iqokobhe kunye nokuphosa utyalo-mali, bayayifumana le nto. Inkqubo ayilothando oluzenzekelayo; yincwadana yemigaqo, umaleko-ngowesithethe. Ukufuma ngaloo mini, ixesha lokumisa phakathi kweedyasi, intlama yentlabathi yestucco—inguqu nganye ishiya umnwe wayo kumphezulu wokugqibela wokusalwa. Yifumane engalunganga, kwaye ufumana iqokobhe elikhangeleka ligqibelele de libethe eziko, emva koko liyasilela ngentlekele. Ndiyibonile. Ibhetshi yemizimba yevalvu yecandelo leoyile negesi, yonakalisiwe ngenxa yokuba igcisa elitsha lileqise imijikelo yokomisa. Amaqokobhe ayekhangeleka elungile, kodwa abamba ukufuma. Uxinzelelo lomphunga ngexesha lokugalelwa lilingana namaqamza angaphakathi kunye nentsimbi ekrazukileyo. Oko $20,000 isifundo kumonde.
Yiyo loo nto intsebenziswano kunye necala lomatshini le-Foundry lingenakuxoxisana. Masithi uphosa impompo yempompo kwintsimbi ephindwe kabini. I-casting iya kuba nesibonelelo sempahla. Iqela lomatshini le-CNC kufuneka liqonde ukugqwetheka okunokwenzeka, isiphumo solusu, kwaye apho ukushwabana okunokwenzeka kunokubakho ukulungiselela ukusikwa ngokuchanekileyo. Xa ulwahlulo lokuphosa kunye ne-CNC luphantsi kophahla olunye, njengaseQingdao Qiangsenyuan Technology Co., Ltd., loo loop yempendulo iqinile. I-machinist inokuhamba ukuya kumgangatho we-Foundry, ikhomba kwindawo yesango elinengxaki kwisampuli, kwaye banokuhlengahlengisa inkqubo yokungena kwi-run elandelayo. Oko kudityaniswa kuguqula iprototype ibe yinxalenye yemveliso esebenzayo.
Ukukhethwa kwezinto eziphathekayo ngomnye umaleko. Abantu bakhankanya intsimbi engatyiwayo kwaye bacinge ukuba yenziwe. Kodwa ngaba sithetha ngo-304 ngokutya okuqhelekileyo, okanye i-17-4 PH yamandla, okanye i-super duplex yeemekobume zekloridi? Kwizicelo zobushushu obuphezulu, utsibela kwi-nickel-based alloys njenge-Inconel 718. Nganye kwezi ziziphatha ngendlela eyahlukileyo ngexesha ukulahlwa kwewax ngokwesiko inkqubo. Iialloys zenickel, umzekelo, zi-viscous. Azihambi njenge-aluminiyam. Inkqubo yakho yokungena kufuneka ibe nesisa ngakumbi, ubushushu bakho bokugalela kufuneka buchaneke ukunqanda ulwahlulo. Ipateni yewax yencakuba ye-Inconel turbine ayiyomilo nje; luyilo lolawulo lobushushu.
Apho iSiko Sidibana neLizwe lokwenyani: Ibali leGear Case
Ndikhumbula iprojekthi yenkqubo yokuqhubela phambili elwandle. Umxhasi wayedinga i-custom gear case-house-complex iziteshi zangaphakathi zokupholisa, iindawo zokunyuka eziye zaphonswa ukuze zigweme iindawo ezibuthathaka ezivela kwi-welding, kwaye yonke into yayifanele ibe kwi-nickel-chromium alloy yokuxhathisa amanzi olwandle. Imodeli yeCAD yayikhangeleka icocekile. Kodwa umjikelo wokuqala weprototyping awuphumelelanga. Hayi ngokumangalisayo, kodwa ngokufihlakeleyo. Uvavanyo loxinzelelo lubonakalise i-micro-porosity kwicandelo elibalulekileyo eludongeni.
Ukuphendula kwamadolo kukugxeka isinyithi. Kodwa oyena nobangela yayingumthwebeba. Ukwakhiwa kwewax yantlandlolo yayinothuthu oluphezulu kancinci. Xa yatshiswayo, yashiya intsalela encinci, eethe-ethe eyafunxwa liqokobhe leceramic, idala indawo ebuthathaka yendawo eyathi isinyithi esinyibilikisiweyo sangena kuyo, sibangela isiphene. Isisombululo yayingekokutshintsha ingxubevange; kwakukutshintshela kwi-wax enothuthu oluphantsi, i-polymer ephuculweyo yepateni. Yabiza ngaphezulu, kodwa yawusombulula umba. Lo ngumsebenzi we-grunt ukulahlwa kwewax ngokwesiko ukuba akukho mntu uthetha ngayo. Yinzululwazi yezixhobo, hayi imizobo nje.
Sisebenze neqela lobunjineli, silungisa uyilo ukubandakanya uyilo olufihlakeleyo kwiindawo umyili ebecinga ukuba zinokubiyelwa ngokuthe tye, songeza iimbambo ezincinci eziqinisayo ezingaphazamisani nomsebenzi kodwa ziqinisekise imfezeko yokungunda. Inxalenye yokugqibela, emva kweeprototypes ezintathu eziphindaphindayo, iphumelele yonke i-NDT kunye novavanyo loxinzelelo. Ikwinkonzo ngoku kwiinqanawa zenkonzo zaphesheya kolwandle. Iwebhusayithi yomthengi inokubonisa nje imeko yegiya emenyezelayo, kodwa kuthi, libali le-wax chemistry kunye neengxoxo zobunzima bodonga.
I-Machining Handshake: Akukho Ukuphosa siSiqithi
Oku kubalulekile. Awusoze uhambise nje isakhelo ekrwada. I ukulahlwa kwewax ngokwesiko yi, kwi-95% yeemeko zoshishino, i-close-net-shape shape blank. 'Ukugqiba' akubhufu; kukuchaneka komatshini weCNC ukuya kwimilinganiselo yokugqibela. I-synergy apha yiyo yonke into. Ukuba indlu yokuphosa kunye nevenkile yomatshini ngamaqumrhu ahlukeneyo, ulahlekelwa ukunyaniseka. Ukunyamezelana kuyalahleka ekuguquleleni.
Kumsebenzi odibeneyo, inkqubo ayinamthungo. I-Foundry ivelisa i-casting enemigangatho echazwe kwangaphambili-ezi ngamanqaku esalathiso aza kusetyenziswa ngumatshini we-CNC. Bayazi ukuba singakanani isitokhwe ekufuneka sishiye (ngokuqhelekileyo i-1-3mm, kodwa ngamanye amaxesha incinci njenge-0.5mm kwiimpawu ezibalulekileyo). Kwinkampani efana ne-QSY, esi sisonka sabo kunye nebhotolo. Bangakwazi ukuphosa umzimba wevalve yentsimbi engenasici kunye neeflanges ezidibeneyo, kwaye isebe labo langaphakathi le-CNC liya kugaya izitywina zobuso, libhobhoze kwaye licofe imingxuma yebholiti, kwaye lithwale isihlalo sevalve yangaphakathi-zonke zibhekisa kwiidatum ezifanayo zokuphosa. Oku kuqinisekisa ukugxila kunye nokulungelelaniswa ongenakukwazi ukufezekisa ngokudibanisa okanye ukudibanisa amaqhekeza ahlukeneyo.
Ndiye ndahlola iindawo zonikezelo oludityanisiweyo. Ukuphosa kuvela kumthengisi omnye, umatshini ukusuka komnye. Usomashishini, ukubetha unyamezelo oluqinileyo, unokusika ulusu oluphosiweyo kunye nesithuba esingaphantsi komhlaba esingabonakaliyo. Inkunkuma. Okanye okubi ngakumbi, isiphene esifihlakeleyo. Xa idityanisiwe, iqela lomatshini liyabazi 'ubuntu' bokuphosa-bayayazi apho kunokwenzeka khona ukuncipha, ngoko baya kulungelelanisa iindlela zabo zesixhobo. Banokwenza uvavanyo lokuqina olukhawulezayo kwindawo kwaye bazise i-Foundry ukulungelelanisa ukuphatha ubushushu kwibhetshi elandelayo. Le nto ivaliweyo yeyona nto yenza ukuba ukuveliswa kwesiko lokwenyani kuthembeke.
I-Alloy Conundrum: Ngaphezulu kwePhepha leDatha
Abathengi beza nespekthi yezinto: ASTM A351 CF8M. Leyo yintsimbi esemgangathweni. Kulungile. Kodwa iipropathi zoomatshini kunye nokunganyangeki kwe-corrosion ye-alloy ilawulwa ngokuthe ngqo kunyango lwe-thermal emva ukulahlwa kwewax ngokwesiko. Ulwakhiwo lwe-as-cast luyaphuka, kunye ne-carbides eguquguqukayo kunye nemida yeenkozo. Udinga isisombululo se-annealing anneal treatment treatment - ukufudumeza ukuya malunga ne-1100 ° C kwaye uyicime ngokukhawuleza ukubuyisela ezo carbides kwisisombululo.
Ukucima yinto ekhohlisayo. Cima ngokucotha kakhulu, kwaye i-carbides iphinda iphinde ibe yimvula, ibulala ukuxhathisa umhlwa. Cima ngokukhawuleza kakhulu kwindawo entsonkothileyo, enodonga olucekethekileyo, kwaye ubangela ukugqwetheka okanye ukuqhekeka. Sisenzo sokulinganisa. Kwi-cobalt okanye i-nickel-based superalloys, unyango lobushushu lunzima ngakumbi, luhlala lubandakanya imijikelo yokuguga ukukhawulezisa izigaba zokuqinisa. Awunakuvele ukhuphele le nto kwisixhobo sobushushu esiqhelekileyo. Kufuneka ibe yinxalenye yenkqubo yokuhamba. I-Foundry kufuneka ibe nolawulo okanye iqabane elithembekileyo kakhulu kweli nqanaba. Inxalenye inokuphoswa ngokugqibeleleyo kwaye yenziwe ngoomatshini, kuphela ukuba yonakaliswe eziko. Ndiyibonile isenzeka ngebhetshi yezixhobo ezininzi. Amaphepha athi baphathwe ubushushu. Babengekho. Basilela ebaleni kwiinyanga nje ezimbalwa ngenxa yoxinzelelo lwe-corrosion cracking. Oyena nobangela? Isivamvo sobushushu esaphukileyo kwisithando somlilo esingazange sibonwe.
Apha kulapho abaqhubi bexesha elide banomphetho. Bakhe inkumbulo yeziko. Bayazi ukuba ubushushu obuthile be-alloy obusuka kumboneleli othile budla ngokubaleka kwisiphelo esisezantsi sesiqulatho sesilicon, esichaphazela ubumanzi, ngoko ke baya kulungelelanisa iqondo lobushushu le-15 degrees. Olo hlobo lolwazi alukho kwincwadi yesandla; ikwi-notepad kwiofisi yomphathi we-Foundry.
Ukujonga kwi-Horizon: Hayi nje ukuphindaphinda, kodwa ukuVumela
Ikamva le ukulahlwa kwewax ngokwesiko ayikokwenza iikopi ezingabizi kakhulu. Imalunga nokwenza uyilo olungenzekiyo ngayo nayiphi na enye indlela. Cinga ngengcebiso yesitofu se-monolithic esineendlela zokupholisa zangaphakathi ezilandela iprofayili ye-aerodynamic-ayikwazi ukuyimatshini, ayikwazi ukuyikhahlela. Uyiphose. Okanye utyando olufakelwayo olunobume obunobukrolwe bomphezulu odibanisa amathambo adityaniswe kumbindi oqinileyo. Oko kukuphosa kotyalo-mali.
Umsonto wedijithali uyaqina. Ngoku, singathatha imodeli ye-CAD, siqhube isoftware yokulinganisa ukuqikelela ukuncipha kokuqina kunye neendawo ezishushu, kwaye siguqule uyilo lomthi we-wax ngedijithali ngaphambi kokuba usike isixhobo. Oku kunciphisa prototype iterations ukusuka mhlawumbi ezine ukuya enye okanye ezimbini. Kodwa isoftware ayisiyiyo i-oracle; sisikhokelo. Usamdinga umntu ukuba atolike iziphumo zakhe, ukwazi ukuba indawo efanelekileyo yokulinganisa isango ayinakwenzeka ukukhupha isango ngaphandle kokonakalisa indawo. Umsebenzi wobugcisa awupheli; inyukela phezulu kwinqanaba lokulungiselela idijithali.
Kumenzi, isindululo sexabiso siyatshintsha. Akusekho ukuba siphosa isinyithi. Sibonelela ngesixhobo sesinyithi esisebenzayo, esinesidima esiphezulu kuyilo lwakho lwedijithali, nayo yonke imathiriyeli kunye nenkqubo engqongqo ethi amashumi amathathu eminyaka okujongana nentsimbi, intsimbi, intsimbi, kunye nezo ngxubevange ezikhethekileyo ezikufundisayo. Ungayibona le ndlela kwisiza esifana ne-tsingtaocnc.com-ayisiyonto ikhanyayo, iyinyani. Idwelisa izakhono (ukuphosa, umatshini, izixhobo) njengamanyathelo adityanisiweyo kwindlela enye yokuhamba. Libali lokwenyani elo. Imveliso yokugqibela ayikokuphosa; yinxalenye eqinisekisiweyo, ekulungeleyo ukuyifaka efike ngexesha kwaye isebenza. Yiloo nto egcina ivenkile efana ne-QSY isebenza ngaphezu kweminyaka engama-30 kwishishini elinzima. Ayingomlingo; kuqwalaselwe unglamorous, iinkcukacha ezibalulekileyo ezenzeka phakathi kwegumbi wax kunye nomatshini CNC.
