Xa usiva 'umthengisi wewax olahlekileyo', abantu abaninzi bafanekisela umzi-mveliso ukhupha amalungu afanayo, alula. Leyo yimbono yokuqala ephosakeleyo. Inyani ikude kakhulu kwaye inomdla ngakumbi. Ayikokwenza nje ipateni yewax kwaye uyinyibilikise; imalunga nokulawula izinto eziguquguqukayo—amazinga okucutheka, ukunyameka kweqokobhe, ulwelo lwealloyi—olutshintshayo ngomsebenzi ngamnye. Umthengisi olungileyo akangomthengisi nje; Bangamaqabane asombulula ingxaki abone izinto eziliwaka zingahambi kakuhle kwaye uyakwazi ukulungisa iwaka-nokuqala. Igama ngokwalo, 'umniki-nkonzo', liziva lingenzi nto ngokona kufunwa lubudlelwane.
Ngaphaya Kwencwadana: Yeyiphi Izakhono Ezona Zibalulekileyo
Uya kubona uluhlu lwewebhusayithi ezininzi 'zokwenziwa kotyalo-mali' kunye 'nokubunjwa kweqokobhe' ngokungathi ziyatshintsheka. Ziyazalana, kodwa umahluko ubalulekile ekuchanekeni. Ukungunda kweqokobhe, okuhlala kusetyenziswa isanti ebotshelelwe ngentlaka, kumnandi kwiijometri ezithile kunye nemiqulu, kodwa xa uthetha ngeepaseji ezintsonkothileyo zangaphakathi okanye umphezulu ogqityiweyo ongaphantsi kwe-125 Ra, ungaphakathi ngokuqinileyo. ukulahlwa kwewax elahlekileyo intsimi. Apha kulapho amava okwenene evenkile abonisa khona. Inkampani efana neQingdao Qiangsenyuan Technology Co., Ltd. (QSY), namashumi amathathu eminyaka, kusenokwenzeka ukuba inenkumbulo yeziko yokwazi ukuba yeyiphi indlela emayithathwe ngaphandle kovavanyo olubanzi kunye neempazamo. Bakhankanya ukusebenza kunye ne-cobalt kunye ne-nickel-based alloys-yiyo xelela. Ukuphatha ezo exotics akukho nje ngokuba neziko; imalunga nokulawula wonke umjikelo we-thermal ukunqanda ukukrazuka okushushu kunye nokuqinisekisa i-metallurgy engaguqukiyo. Awukwazi ukukhohlisa ukuba ubuchule.
Ndikhumbula iprojekthi yecandelo leinjini yomoya kwi-Inconel 718. Imizobo yokuqala ibifuna unyamezelo, ngokungafihlisiyo, olunethemba lemeko ye-as-cast. Umntu onamava umthengisi inokuba usanda kunqwala wacaphula, nto leyo ekhokelela kwiphupha elibi kakhulu lomatshini kamva. I-back-and-out yayimalunga nokuqhelanisa kwakhona inxalenye emthini ukunciphisa ukuphazamiseka, ukulungelelanisa ukuyila kwesango ukuze kuqinisekiswe ukuqina kolwalathiso, kunye nokuvumelana malunga nokuba yeyiphi imiphezulu ebalulekileyo eya kushiywa kunye nesitokethi esongezelelweyo. Olo thethwano yinkonzo yokwenyani. Ayikho kwiphepha langaphambili lewebhusayithi yabo, kodwa yinto abayithengisayo iminyaka yabo engama-30.
Icala lomatshini alinakuxoxisana. Nayiphi na enzulu umthengisi olahlekileyo we-wax kufuneka ibe nezakhono ezihlanganisiweyo ze-CNC. Ngoba? Kuba isithembiso 'sobume obukufutshane nenetha' sotyalo-mali sisathetha ukuba kufuneka ubethe imilinganiselo yokugqibela kumphezulu wokukhwelana, imisonto, kunye namabhore achanekileyo. Ukuba ukuphosa kunye nomatshini kuphantsi kophahla olunye, babelana ityala-kunye nesisombululo. Oomatshini baqonda iziphene ezinokubakho (njengeendawo ezincinci ze-porosity), kwaye iinjineli zezobuchwephesha ziyaziqonda iimfuno zoomatshini bokuqina okungaguqukiyo. Ukukhankanywa okucacileyo kwe-QSY komatshini odibeneyo we-CNC ayilophawu lwebhonasi; yimfuneko esisiseko yokuba liqabane elinobuchule kuyo nantoni na engaphaya komsebenzi wokuhombisa.
Imigibe: Apho iiProjekthi zidla ngokuphuma kumzila kaloliwe
Iintsilelo zonxibelelwano ziphezulu kuluhlu. Ayikhe imalunga nokuthumela ifayile yeCAD. Owona mba uxhaphakileyo kukucinga ukuba umniki-nkonzo uyazazi izinto zakho ezibalulekileyo ezingachazwanga. Ngaba ukunciphisa ubunzima yinjongo epheleleyo, nangona iindleko zeyunithi ephezulu kancinane? Ngaba ixesha lokukhokela libaluleke ngakumbi kunokufikelela owona mphezulu ugqwesileyo? Kufuneka uyipeleke. Oku ndakufunda kabuhlungu kwasekuqaleni. Besifuna ibhetshi yemizimba yevalvu yentsimbi engenastainless, kwaye ndajolisa ngokupheleleyo kwi-spec yokulinganisa yoxinzelelo. Umthengisi uhanjiswe ngokugqibeleleyo kule nkcazo, kodwa iinxalenye zineendlela ezincinci zotyalo-mali kwizinto ebekufanele ukuba bubuso obubonakalayo kumthengi. Yayilityala lam lokungaqaqambisi ukuba ubuhle beyona mfuno iphambili yorhwebo. Umthengisi olungileyo uya kubuza le mibuzo, kodwa awukwazi ukuxhomekeka kuyo.
Isiqinisekiso sezinto eziphathekayo ngomnye umbulali othuleyo. Ukuchaza u-304 engenanto akwanelanga. Ngaba isicelo sidinga ikhemistri eqinisekisiweyo yokunyibilika kwilitye lokusila? Ngaba ifuna iingxelo zovavanyo ngoomatshini ukusuka kumakhuphoni afakwe ecaleni kwendlela yokuvelisa? Kwii-alloys zabo ezikhethekileyo, umthengisi ofana ne-QSY kufuneka akwazi ukubonelela ngolu landelelwano, kodwa kufuneka ucacise inqanaba lamaxwebhu afunekayo. Ndibone iiprojekthi zilibazisekile iiveki ngenxa yokuba le nto ayizange icaciswe ngaphambili, kwaye isiseko kuye kwafuneka sikrazule ukuze sifumane iziqinisekiso zezinto eziphathekayo emva kwenyani.
Emva koko kukho i-prototype trap. Ukufumana isampulu yeprototype entle, egqitywe ngesandla kulula. Umceli mngeni kukuphindaphinda loo mgangatho kwimveliso eqhutywa ngamaqhekeza angama-500 okanye angama-5000. Ukuhambelana kwenaliti ye-wax, inkqubo yokudipha i-automated slurry, ukulinganisa i-autoclave ye-dewaxing-ezi zinto zihlukanisa umntu othanda ukuzilibazisa kwimveliso yangempela. umthengisi. Cela ukubona iitshathi zabo zolawulo lwenkqubo yobukhulu beqokobhe okanye ubushushu beziko. Ukuvuma kwabo ukubonisa oko kuxela ngakumbi kunayo nayiphi na igalari yeefoto ezimenyezelayo.
Ukuphonononga uMlingane: IiNkcukacha ezingezizo
Ulibale uluhlu lwezixhobo ezithandekayo ekuqaleni. Qala ngempendulo yabo kwisicelo sekowuti (RFQ). Ngaba babuza imibuzo ekrelekrele, ecacisayo malunga nomsebenzi, indibano, kunye nokusebenza okwesibini? Okanye ngaba bathumela nje ixabiso kunye nexesha lokukhokela? Owokuqala ubonisa uthethathethwano. Ndihlala ndiphosa into engaqhelekanga yejometri kuvavanyo lwe-RFG-i-undercut engeyomfuneko ngokungqongqo, okanye inguqu yobunzima bodonga. Umbuzo wabo malunga nelo nqaku undixelela ukuba ngaba ngokwenene bahlalutya inxalenye yokwenziwa kwezinto okanye baqhuba nje ukubala umthamo.
Undwendwelo lwesiza alunakuthathelwa indawo. Jonga kwigumbi leweksi. Ngaba ilawulwa yimozulu? Amaqondo obushushu ayayonakalisa imilinganiselo yepateni. Jonga indawo yokugqiba. Ngaba amalungu alungelelaniswe ngumsebenzi, okanye yimfumba enesiphithiphithi? Jonga izixhobo zabo zokuhlola. I-CMM ilungile, kodwa ngaba abaqhubi bayayazi indlela yokuyisebenzisa ngokufanelekileyo kuhlolo lwenqaku lokuqala? Imeko yogcino lwezixhobo zabo ithetha lukhulu ngoqeqesho lwabo. Iipateni ezigugileyo okanye ezingagcinwanga kakuhle ziyindlela ethe ngqo eya kwidimensional drift.
Ekugqibeleni, xoxa ngokusilela. Babuze ngokungafihlisiyo: Sesiphi esona siphene sixhaphakileyo udibana nenxalenye efana nale, kwaye usilawula njani? Ukuphoswa kwentsimbi, inokuba yi-slag inclusions. Kwi-aluminiyam enodonga olucekethekileyo, inokuba yi-mistruns. Impendulo yabo kufuneka ikhawuleze kwaye icace, iiparamitha zenkqubo yereferensi efana nobushushu bokugalela okanye ubushushu bangaphambili. Impendulo engacacanga yiflegi ebomvu. Inkampani enobomi obude be-QSY kufuneka ibe nethala leencwadi lezi nkumbulo zokusilela, eyona inshurensi yakho ilungileyo.
Ukudityaniswa kokuCasa kunye noMatshini: Ityala elikwiNqaku
Kulapho ixabiso lokwenyani lenziwa khona. Masithathe indlu yempompo kwintsimbi ephindwe kabini. Cast iivoluthi ezintsonkothileyo zangaphakathi nge ukulahlwa kwewax elahlekileyo, emva koko umatshini wobuso be-flange, imingxuma yebholithi, kunye neendawo zokutywina. Ukuba ezi ziivenkile ezahlukeneyo, ufaka ukuphathwa kabini, i-QA ephindwe kabini, kunye nomdlalo wetyala ongunaphakade ukuba umsebenzi womatshini utyhila i-pore engaphantsi komhlaba. Ivenkile edibeneyo efana nale ichazwe kuyo https://www.tsingtaocnc.com iyayiphelisa loo nto. Oomatshini babo basebenza kumhambi ofanayo kunye ne-Foundry. Banokucwangcisa ukuqhelaniswa nokusa kunye nesango lokungena ukushiya isitokhwe esongezelelweyo kanye apho kuya kuba khona ukunqunyulwa kokugqibela, ukwandisa isivuno kunye nokunciphisa ixesha lomatshini.
Ndisebenze nomthengisi kwindawo yokulinganisa yaselwandle apho oku kudityaniswa kwasindisa iprojekthi. Inxalenye ye-as-cast ibe nenguqu encinci engundoqo. Endaweni yokuyichitha, kwathethwana neqela lomatshini ngoko nangoko. Baye bahlengahlengisa inkqubo ye-CNC kubhabho ukuya kwamva nje, bahlala ngaphakathi komzobo wokunyamezela ukutyeba kodonga kodwa besebenzisa 'inyama' ekhoyo. Esi sigqibo senziwe ngeeyure kuba omabini amaqela ayekwisakhiwo esinye, enenjongo enye. Obo buchule buxabisekile kwaye akufane bubhengezwe.
Ulwazi oluphathekayo luyawela, nalo. Machining nickel-based alloys lirhamncwa. Ukwazi eyona microstructure kunye nobulukhuni obuvela kwisiseko kuvumela abadwelisi benkqubo be-CNC ukuba bakhethe isantya esifanelekileyo, ukutya, kunye nejeometri yesixhobo ukusuka kwisiqwenga sokuqala. Ikhusela ukuphulwa kwesixhobo kwaye iqinisekisa ingqibelelo yomhlaba. Xa inkampani enye ilawula lonke uhambo ukusuka kwisinyithi esinyibilikisiweyo ukuya kwinxalenye egqityiweyo, ukuqhelana kwezinto ezinzulu kuba luncedo olunamandla kumthengi ngokwemigaqo yokungaguquguquki kunye nolawulo lweendleko.
Ukuyisonga: Imalunga nokuBumbana okuLawulwayo
Ngoko, ukufumana a umthengisi olahlekileyo we-wax ayingomsebenzi wokukhangela; yinkqubo yokuhlola umdibanisi wobugcisa. Amagama angundoqo-ukuphosa utyalo-mali, i-CNC machining, i-alloys ekhethekileyo-ziitikiti zokungena nje. Uvavanyo lokwenyani lwenzeka kwimibuzo abayibuzayo, ukungafihlisi abakubonisayo malunga nolawulo lwenkqubo yabo, kunye nokukwazi kwabo ukucinga ngokubhekiselele kulo lonke ikhonkco lokuvelisa, hayi nje inyathelo labo kulo.
I-firm efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ibonisa iprofayili ehlola iibhokisi ezibalulekileyo: amashumi eminyaka embali (ecebisa ukomelela kunye nezifundo ezifundiweyo), inkqubo ecacileyo yenkqubo ukusuka kwi-shell molds ukuya kwi-high-precision investment casting, kunye nokudibanisa okubalulekileyo komatshini.
