Xa uqala ukukhangela abaxhasi ukubumba inaliti yesinyithi, kukho lo mgibe uxhaphakileyo wonke umntu ubonakala ewela kuwo ekuqaleni: uxhonywa kwi-specs yomatshini okanye ixabiso lemathiriyeli yesiseko ngekhilogram. Ngumdlalo wamanani ephepheni. Kodwa emva kweeprojekthi ezimbalwa, uyaqonda ukuba umahluli wokwenyani ayingomthamo weendaba; yinkqubo yendalo iphela eyijikelezileyo-ukungaguquguquki kokwenziwa kwe-feedstock, ulawulo lwenkqubo ebophelelayo, kunye neso sigaba sibalulekileyo, esihlala singahoywa, sintering. Iivenkile ezininzi zibanga isakhono se-MIM, kodwa ubuchule babo bunokuba yiminyaka emihlanu kubunzulu benaliti yeplastiki ngomgubo wentsimbi ofakwe njengengcinga emva koko. Oko kungafaniyo kulapho iiprojekthi zizinzile okanye zisilele ngokuzolileyo.
Ulwahlulo olungundoqo: IiMasters zeNkqubo vs
Ungatsho ngesiqhelo kwincoko enye. Umboneleli wokwenyani wenkqubo-ephakathi uya kuyikhokelela kwangoko intetho ukuya kwijometri yenxalenye yakho, ukuguquguquka kobunzima bodonga, kunye neendawo zoxinzelelo ezicetyiweyo. Bacinga malunga nokuba umgubo uya kuqukuqela njani kweli candelo lincinci lomnqamlezo kunye nendlela umbopheli oza kuphuma ngayo. Abanye, inxalenye etyhalayo, bakhokela ngesatifikethi sabo se-ISO kunye nobungakanani bomyalelo obuncinci. Ndifunde oku ngendlela enzima kwiprojekthi yokuqala yecandelo lesixhobo sotyando. Sahamba nomthengisi othengiswe kakuhle owayenazo zonke iziqinisekiso ezifanelekileyo. Iisampuli zenqaku lokuqala zazigqibelele. Kodwa kwimiqulu yemveliso, sabona uzinzo olungahambelaniyo lwe-dimensional kumacandelo e-cannulated. Ingxaki? Ulawulo lwabo lobushushu bendawo yomlilo belungaqinanga kwi-17-4 PH engenabala esiyibalulayo. Zazimiselwe amabanga aqhelekileyo. Ilahleko ayizange iphelele nje; ibikumgca wexesha kunye nokuthembela.
Apha kulapho imvelaphi kwiinkqubo ezichanekileyo ezinxulumeneyo zokwenza isinyithi iba yinto exabiseke kakhulu. Thatha inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ungazifumana apha https://www.tsingtaocnc.com. Ngoku, ubuso babo basesidlangalaleni bungaphezulu kweminyaka engama-30 kubunjwa beqokobhe kunye nokuphosa utyalo-mali, kunye noomatshini be-CNC. Ngomntu ofuna nje abaxhasi ukubumba inaliti yesinyithi, zisenokungaveli kuqala. Kodwa le yinxalenye enomdla. Ifemu enesiseko esinzulu kunye neengcambu zoomatshini, esebenza ngayo yonke into ukusuka kwintsimbi ekhandiweyo ukuya kwi-nickel-based alloys, izisa isiseko sengqondo yesayensi yezinto ezahlukeneyo etafileni. Kwi-MIM, ngokukodwa ngee-alloys ezikhethekileyo, ulwazi lwe-metallurgical oluvela kwicala lokuphosa-indlela iinkozo ezenza ngayo, indlela i-alloys eziphatha ngayo phantsi kobushushu-iguqulela ngokuthe ngqo ekulawuleni iprofayili ye-sintering. Akunjalo nje ngokuqhuba iziko; imalunga nokuqonda inguqu kwinqanaba lemolekyuli ukusuka kwinxalenye emdaka engenanto ukuya kwintsimbi yokugqibela exineneyo.
Anditsho ukuba yonke indlu yokutshala imali inokwenza iMIM. Lirhamncwa elahlukileyo. Kodwa xa umboneleli onjalo ethatha isigqibo sokubonelela nge-MIM, indawo yabo yokuqala yimathiriyeli kunye neempawu zokugqibela zemilo yomnatha, hayi nje inyathelo lokubumba. Balindeleke ukuba babone inxalenye iyonke: Singabumba uninzi lwayo nge-MIM, kodwa lo msonto ubalulekileyo unokufuna umatshini we-CNC wasemva kwenkqubo yemfezeko, kwaye nantsi indlela esilawula ngayo olo jongano. Loo mbono idibeneyo yigolide.
INyaniso eseMgangathweni: Uphicotho-zincwadi olungaPhaya kweNcwadana
Ngoko, wenza njani ugqirha? Iwebhusayithi, njengeQSY's, ikuxelela into-izixhobo, iinkqubo zesibini. Uphicotho-zincwadi lukuxelela ukuba njani. Kufuneka uhambe phantsi. Kwi-MIM, ndihlala ndisiya kwindawo yokugcina ukutya kuqala. Ngaba ilawulwa ubushushu kunye nokufuma? Ngaba kukho inkqubo ecacileyo yokulandela umkhondo? Emva koko, indawo yokuphumla. Ngaba yahlukile kumgangatho wokubumba ukukhusela ungcoliseko? Yeyiphi indlela-i-solvent, i-catalytic, i-thermal? Nganye ineempembelelo kwinxalenye yobukhulu kunye nemathiriyeli. Ivumba ngamanye amaxesha liyakwazi ukukuxelela ngaphezu kwentetho yomphathi.
Indawo ye-sintering yintliziyo. Jonga iinkuni zokugcina iziko. Buza malunga nexesha lokugqibela i-thermocouples ilinganisiwe. Kumthengisi osebenza nge-cobalt-chrome okanye i-nickel alloys, cela ukubona iiprofayili zomsebenzi wamva nje. Kufuneka bakwazi ukutsala igrafu ebonisa irempu yobushushu echanekileyo, amaxesha okubamba, kunye namazinga okuhamba kwerhasi. Ukuba bayathandabuza, loo nto iflegi ebomvu. Ndikhumbula ndityelela indawo eyayibonakala icocekile, kodwa iitreyi zazo zomlilo zazigqwethekile. Loo nkcukacha incinci ikhokelela kulwabiwo lobushushu olungalinganiyo kunye nenxalenye ye-warpage. Babegxile kakhulu ekuthengiseni oomatshini babo bokubumba abatsha kangangokuba baphoswe sisixhobo esisisiseko.
Apha kulapho umnikelo odityanisiweyo wokuphosa, iMIM, kunye nokwenza ingqiqo. Indawo entsonkothileyo inokuba nomzimba wayo wenziwe ngokusasazwa kutyalo-mali kwiimpawu ezithile zangaphakathi, icandelo elincinci elenziwe ngeMIM ngeenkcukacha eziphucukileyo, kwaye zonke zigqitywe kwiibhedi ze-CNC. Umthengisi onokuthi aqhubele kulo lonke ikhonkco lexabiso ngaphakathi, njengenkampani eneprofayili ye-QSY, inciphisa umngcipheko wezithuba zonxibelelwano kunye nokupakisha ukunyamezela. Ujongene neqela elinye lesinyithi kunye nelobunjineli, hayi iikontraki ezintathu ezahlukeneyo ezikhomba ngeminwe.
IiNuances zeMathiriyeli: Ayisokuze iNtsimbi nje engenaStainless
Owona mqobo uphambili ekufumaneni ulwazi lubalulo lwemathiriyeli yegeneric. Ukuthi ufuna intsimbi engatyiwayo ye-MIM kufana nokuthi ufuna isithuthi sokubaleka. Ayinantsingiselo. Ngaba sithetha nge-316L yokumelana nokubola? 17-4 PH yokuqina kwemvula? I-powder morphology, ukuhanjiswa kobungakanani besuntswana, kunye nenkqubo yokubopha ilungelelwaniso nganye. Umthengisi olungileyo uya kubuza imibuzo yakho yezinto eziphathekayo. Ukuba uyikhuphele kumzobo owenziwe ngoomatshini, kufuneka babuyisele umva. I-MIM ifezekisa kufutshane noxinano olupheleleyo, kodwa iimpawu zomatshini zahlukile kwisitokhwe sebha esetyenzisiweyo. Ubomi bokudinwa okanye ukufikeleleka kwemagnethi kusenokwahluka.
Ababoneleli abanembali ende kwii-alloys ezikhethekileyo, njengoko kubonisiwe kwi-intro ye-QSY, banenzuzo apha. Kusenokwenzeka ukuba bazifumene kwaye bavavanya umgubo ovela kubavelisi abohlukeneyo. Bayazi ukuba umgubo osuka kumniki-nkonzo A unokuba ne-sintering shrinkage eyahluke kancinane kunomgubo osuka kumthengisi B, nakwibakala elifanayo lealloyi. Baza kuba naloo datha. Baya kuba nobuchule ngakumbi bokuphatha amaqhinga-njenge-alloys esekwe kwi-nickel enovakalelo kumxholo wekhabhoni ngexesha lokuntywila. Olu ayilolwazi lweencwadi; ifakwe kwiibhetshi ezingaphumelelanga kwaye iqhube ngempumelelo kwiminyaka.
Ndakhe ndasebenza kwi-sensor yendlu efuna impendulo yemagnethi elawulwayo. Sichaze i-400-series ezingenastainless. Umboneleli we-MIM okwinqanaba lokuqala uye wasokola ekufikeleleni okungaguqukiyo. Singenise umcebisi ovela kwimvelaphi efana nehlabathi elidibeneyo lokuphosa / le-MIM. Umbuzo wakhe wokuqala wawumalunga nomxholo weoksijini wepowder kunye ne-sintering atmosphere's dew point-izinto ezibaluleke kakhulu kuneparameters zokubumba kuloo meko. Yayiyimbono ezelwe kwiinkqubo ezisekelwe kwiziko, hayi nje ukubumba inaliti.
Ukudityaniswa okunyanzelekileyo: Xa i-MIM ingeyiyo yonke iMpendulo
Olu lubizo olubalulekileyo lokugweba. Eyona iphumeleleyo abaxhasi ukubumba inaliti yesinyithi banyanisekile malunga nemida yenkqubo. I-MIM ikhazimle kwizinto ezintsonkothileyo, ezincinci ukuya kweziphakathi ezinobungakanani obuphezulu. Kodwa kuthekani ukuba inxalenye yakho inesiseko esilula kodwa esinye esichaneke ngendlela engathethekiyo, into eyodwa? Mhlawumbi kungcono kwiMIM eyona fomu kwaye ube nomatshini wokusebenza we-CNC ozinikeleyo obonisa ukunyamezelana kwe-sub-micron. Okanye, kuthekani ukuba inxalenye ifanelekile kakhulu kwi-MIM kodwa inomgodi wangaphakathi ongenakwenzeka ukubophelela? Mhlawumbi indlela ye-hybrid esebenzisa i-soluble core iyafuneka.
Umboneleli owenza kuphela iMIM iza kuzama ukunyanzela yonke indawo kwifestile yenkqubo yabo, ngamanye amaxesha ibeka esichengeni uyilo. Umthengisi onepotfoliyo yokuvelisa ebanzi, njengalowo unikezela ngokuchaneka kunye nomatshini we-CNC, kunokwenzeka ukuba acebise isisombululo somxube. Bayi-agnostic kwinkqubo; bakhathalele eyona ndlela isebenzayo, ethembekileyo kwi-spec yokugqibela. Kwindawo yabo, ukubona ukuba banikezela ngokubunjwa kweqokobhe kwiimilo ezinkulu okanye ezilula kunye nomatshini we-CNC weempawu ezichanekileyo zindixelela ukuba baxhotyisiwe ukucinga ngale ndlela. Ibonisa inkcubeko yobunjineli-centric kunokuba inkcubeko yokuthengisa inkqubo enye.
Umzekelo, sasinecandelo eliquka i-flange encinci, e-radial. I-MIM ecocekileyo isengozini ye-warpage. Umniki-nkonzo (engafaniyo neprofayile echaziweyo) ucebise ukuba wenze i-hub engundoqo nge-MIM yobunzima kwaye uyifake ngaphantsi kancinci kwidayamitha yeflange. Emva koko baye benza ukukhanya kwe-CNC yokuguqula umsebenzi kwiflange ukuyizisa kunyamezelo lokugqibela kunye nokucaca okugqibeleleyo. Oku kwandisa ukomelela kwenkqubo nganye. Isindululo savela kwiqela labo lobunjineli bemveliso, ababenentlanganiso zeveki neveki. Loo ntsebenziswano kunzima ukuyifumana kwivenkile yenkqubo enye.
Iingcinga zokugqibela: Ukwakha uBudlelwane, hayi nje iPO
Ukukhetha a umboneleli wokubumba inaliti yesinyithi ekugqibeleni ifikelela kubunzulu bentsebenziswano. Asiyonto yorhwebo yokuthenga. Uthenga kulwazi lwabo lwenkqubo, indlela yabo yokusombulula iingxaki, kunye nokuzimisela kwabo ukuba cacileyo malunga nemingeni. Isigaba sokuqala se-RFQ singaphezulu nje. Uvavanyo lwangempela luza ngexesha lokuphononongwa kwe-design-for-manufacturability (DFM) kunye nokuqaliswa kwemveliso yokuqala.
Khangela ababoneleli ababuza imibuzo engaphezu kwakho. Ngubani ofuna ukwazi umsebenzi wenxalenye, amaqabane ayo endibano, iimeko zayo zomthwalo. Ababelana ngeengxelo zabo zokuhlalutya ukusilela kwiiprojekthi ezifanayo (kunye neenkcukacha zabaxumi ezihlaziyiweyo, kunjalo). I-digital footprint, njengewebhusayithi ye-QSY ebonisa ukuzibophelela kwexesha elide kwinguqu yesinyithi kuzo zonke iinkqubo, kuphawu oluhle lokuqala. Icebisa uzinzo kunye nolwazi oluqokelelweyo, olunqamlezileyo.
Ekugqibeleni, libala iincwadana eziqaqambileyo ezineendawo ezikhanyayo. Cela utyelelo kwilebhu yabo esemgangathweni. Cela ukubona idatha yabo ye-CPk yomlinganiselo obalulekileyo kumsebenzi oqhuba ixesha elide. Buza ukuba bajongana njani nokutenxa kuxinaniso lwe-sintered. Iimpendulo zabo, ukuthandabuza okanye ukuntywila ngokukhawuleza kwidatha, kuya kukuxelela yonke into. Umboneleli ofanelekileyo uziva engaphantsi njengomthengisi kwaye ufana nokwandiswa kwesebe lakho lobunjineli-eyenzeka ukuba ibe neziko ezimbalwa ezikhethekileyo kunye nokuqonda okunzulu, ngamanye amaxesha kunzima, ukuqonda ukuba umgubo wesinyithi uba yinxalenye ethembekileyo.
