Xa ukhangela 'umenzi womatshini wokubumba isitofu sesinyithi', ngoko nangoko uhlaselwa ziikhathalogu ezimenyezelayo eziqhayisa malunga nokunyanzeliswa kwamandla, umthamo wokudubula, kunye nokudityaniswa kwerobhothi. Kulula ukucinga ukuba umdlalo umalunga neenkcazo zoomatshini. Ngumgibe wokuqala lowo. Ngokwenyani, eyona nto ibaluleke kakhulu ayingomatshini ngokwawo, kodwa ibamba umenzi wayo yonke inkqubo yekhonkco-ukusuka kwindlela yokuziphatha ye-feedstock ukuya kwinkxaso ye-sintering. Umatshini yinto nje enye enexabiso eliphezulu kwinkqubo ethanda ukusilela okuchuliweyo, neendleko ezinkulu.
Umbono ongeyiyo ongundoqo: Umatshini vs
Uninzi lwemibuzo luvela kwiinkampani ezijonge ukuphucula okanye ukuseta umgca omtsha weMIM. Ugxininiso lwabo lubukhali ngelaser kwiyunithi yokutofa. Bafuna ukwazi malunga noyilo lwe-screw, ukuxhathisa ukunxitywa komgqomo, kunye nokuba ine-servo-driven plunger. Ezi ziyasebenza, kodwa zezesibini. Umbuzo oyintloko kufuneka ube: ngaba lo mvelisi uyayiqonda into eyenzekayo ngaphambi kokuba izinto zingene emgqomeni kwaye emva kokuba inxalenye eluhlaza ikhutshwe?
Ndibone ukusebenza kuthenga umatshini okwinqanaba eliphezulu laseJamani kuphela ukuzabalaza kangangeenyanga kunye nokungahambelani komgangatho. Ingxaki yayingengomatshini wokutofa. Yayiyi-feedstock, enikezelwa liqela lesithathu, elaline-binder formulation engazange idibane neprofayile yobushushu echanekileyo yomatshini. Umenzi womatshini, okrelekrele kubuchwephesha, wayenengcebiso eqanda ngokuhambelana kwe-feedstock. Bathengisa isixhobo, kungekhona isisombululo.
Kulapho imvelaphi kwi-metallurgy kunye nokuphosa iba luncedo kakhulu. Thatha inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngaphezulu kweminyaka engama-30 kubumba lweqokobhe kunye nokuphosa utyalo-mali, ukungena kwabo ekuxhaseni imisebenzi ye-MIM kwenza ingqiqo. Abangoomatshini nje abathengisi; baphila kwaye baphefumle isayensi yezinto-insimbi engenasici, i-cobalt-based alloys, i-nickel-based alloys. Xa bejonga a umatshini wokubumba inaliti yesinyithi, bayibona njengenyathelo lokubumba kwisaga ende yokudityaniswa kunye ne-sintering. Lo mbono utshintsha yonke into.
Apho iiNgxaki zokwenyani zifihlwa khona: I-Feedstock kunye ne-Tooling Interface
Makhe sifumane igranular. Indawo yentlungu eqhelekileyo ngumbhobho kunye nokunxitywa kwezikrufu xa kusetyenzwa i-feedstocks ebrasive elayishwe ngomgubo wentsimbi eqinile. Umenzi ocaphula kuphela isixhobo esiqhelekileyo sensimbi kula macandelo yiflegi ebomvu. Kusenokwenzeka ukuba abanawo amava okanye bangenawo amava. Incoko kufuneka itshintshelwe kwizibini eziphathekayo: Yintoni ecetyiswayo yesixhobo sentloko yesikrufu se-17-4PH feedstock? okanye Bubuphi ubomi obulindelekileyo bevalve engabuyiyo xa uqhuba i-tungsten carbide?
Ndikhumbula iprojekthi apho sajongana nentlekele yokunxiba kwiiyure ezingama-50 emva kokuba sihambile. Umatshini wawulungile, kodwa umboneleli we-feedstock kunye nomakhi womatshini babekhombana ngeminwe. Umcebisi onemvelaphi yesiseko-efana neqela le-QSY-iyisombulule. Ucebise uhlengahlengiso oluncinci kumlinganiselo wokucinezelwa kwesikrufu kunye nokutshintshela kwilayini ekhethekileyo, eqinisiweyo. Ulungiso lwavela ekuqondeni ubume bomgubo wentsimbi, into ezalwa yingcali yokuphosa. Iwebhusayithi yabo, tsngtaocnc.com, ingcebiso kobu nzulu, idwelisa ii-alloys ezithile abaziphetheyo, ezibonisa i-material-first mindset.
Obunye ubuqili kulawulo lobushushu. KwiMIM, asithethi ngeqondo elinye lokunyibilika njengenaliti yeplastiki. Imalunga nokulawula iprofayile ye-thermal ye-viscous, i-powder-laden binder system. Iizowuni kufuneka zilawulwe ngononophelo ukuthintela ukwahlukana okanye ukuthotywa kwesibophelelo phambi kwexesha. Umenzi olungileyo uya kuba neenketho ezineenkcukacha, ezingezizo ezisemgangathweni zolawulo lwezowuni kunye nokubekwa kwesinzwa, ehlala iphuhliswa ukusuka kulingo kunye nempazamo ngemathiriyeli yokwenyani.
Ikhonkco leSintering: Ukuxhawula isandla esiLibeleyo
Akukho ngxoxo malunga a umenzi womatshini wokubumba wesinyithi wesinyithi igqityiwe ngaphandle kokuchukumisa i-sintering. Lo ngowona mahluko mkhulu wokubumba inaliti yeplastiki. Ijiyometri yenxalenye eluhlaza, i-gradients yoxinaniso, kunye nokuhanjiswa kwe-binder-zonke zilawulwa yinqanaba lokutofa-zimisela ngokuthe ngqo impumelelo ye-sintering. Inxalenye ebonakala igqibelele ngaphandle kwesikhunta inokujika okanye igqwethe ngokukrakra kwisithando somlilo.
Umvelisi oxabisa ityuwa yakhe uya kuba, okanye uya kusebenzisana ngokukhutheleyo, nobuchule bokuntywila. Bafanele bakwazi ukuxoxa ngezinto eziqhelekileyo zokucutheka kwezinto eziqhelekileyo, ukuba uyilo lwesango luchaphazela njani ukugqwetheka, kwaye bade bacebise iiprofayili zesithando somlilo. Kungenxa yoko le nto inkampani eneprofayile ye-QSY inomdla. Ishishini labo eliphambili ekugaleleni kutyalo-mali-inkqubo ekwaxhomekeke kakhulu kwimijikelo ye-thermal elawulwayo ukutshisa iipateni kunye namaqokobhe e-sinter-ibanika ukuqonda okungaphakathi kwe-thermal debinding kunye ne-sintering kinetics. Sisiseko solwazi esihambelanayo esiguqulela ngamandla ukuya kwiMIM.
Ndiyifunde kabuhlungu le nto. Sakha savelisa icandelo elintsonkothileyo elinodonga olucekethekileyo. Ibumbe kakuhle. Kodwa ekuculeni, yawa. Umthengisi womatshini wayengenamsebenzi. Yayiligcisa lomlilo elitshisayo eliye lafumanisa ukuba isantya sokutofa siphezulu kakhulu, sisenza umahluko woxinaniso olungabonakaliyo emehlweni. Ukulungiswa kwakukwiiparamitha zenkqubo yomatshini, kodwa ukuxilongwa kwavela ekupheleni kwe-sintering. Abavelisi boomatshini abagqwesileyo bacinga njengale gcisa; babona iziko njengomgwebi wokugqibela womsebenzi wabo womatshini.
Izinto ezisebenzayo: Inkonzo, ukwenza ngokwezifiso, kunye noMtshini oLungileyo owaneleyo
Phantsi, awuthengi nje umatshini; uthenga ubudlelwane benkonzo kunye nokubanakho ukwenziwa ngokwezifiso. Kwiivenkile ezixube kakhulu, utshintsho olukhawulezayo lokungunda lubalulekile. Ngaba umenzi uyabonelela ngenkqubo eyomeleleyo yokubambelela ngokukhawuleza? Kwi-R&D okanye iibhetshi ezincinci, ngaba incinci, ubungakanani bokudubula obubhetyebhetye buyafumaneka, nokuba ayiyomodeli yabo yeflegi?
Abavelisi abaninzi batyhala imigca yabo emikhulu, eyona izenzekelayo. Kodwa kwivenkile yomsebenzi enokuthi kwakhona yenza ngokuchanekileyo umatshini weCNC ecaleni-njengeenkonzo ezidweliswe kuzo indawo ye-QSY-uluhlu oluphakathi, umatshini olungele uhlengahlengiso kakhulu unokuba lolona lwabiwo lwenkunzi olukrelekrele. Ukukwazi ukudibanisa umatshini kwi-workflow ebanzi equka ukucwangciswa kwesibini kuyinzuzo ebonakalayo. Umenzi owuqondayo lo mxholo ubanzi unokubonelela ngesikhokelo esingcono.
Emva koko kukho inkonzo. Ngaba banokubonelela ngenkxaso yexesha lokwenyani kwinkqubo yokusombulula ingxaki? Xa ibhetshi entsha ye-feedstock ibangela imiba, ngaba iinjineli zabo ziya kunceda ukulungelelanisa iiparamitha, okanye zithumele nje umkhandi ukuba ajonge i-hydraulics? Umahluko mkhulu. Owangaphambili usebenza njengeqabane lenkqubo, lowo wokugqibela njengomthengisi.
Isiphelo: Ukutshintsha iNqobo yoVavanyo
Ngoko ke, xa kuvavanywa a umenzi womatshini wokubumba wesinyithi wesinyithi, yisa iphepha elithile kwiphepha lesibini. Qala incoko ngesayensi yezinto kunye nokucula. Babuze ngelona bali linzima labo lempumelelo yezinto eziphathekayo. Phanda ulwazi lwabo lweenkqubo zokubopha. Buza malunga nobudlelwane babo nababoneleli bemfuyo kunye nabakhi beziko.
Khangela abavelisi abafakwe kwihlabathi elibanzi lokubumba isinyithi, njengabo banemvelaphi kwi-casting okanye i-metallurgy yomgubo. Indlela yabo yoyilo lomatshini yahlukile ngokwendalo-iphelele ngakumbi. Umatshini uba sisixhobo esichanekileyo sokubumba intlama ephethe isinyithi, kungekhona nje i-plastic injection press kunye nesakhelo esinzima.
Ekugqibeleni, umenzi ofanelekileyo uyakunceda ukuba ujonge yonke inkqubo ye-MIM, hayi nje ukukuthengisela i-asethi eyinkunzi. Bayavuma ukuba ukusebenza komatshini wabo kuqhagamshelwe ngokungenakuhluzwa kwizinto eziguquguqukayo ezinyukayo nezisezantsi. Olo luhlobo lwentsebenziswano olujika utyalo-mali oluyinkunzi olunobungozi lube yintsika yemveliso ethembekileyo. Kuncinci malunga nokuthenga umatshini kunye nokunye malunga nokufumana isiqwenga senkqubo eqinisekisiweyo, esebenzayo.
