Xa uqala ukukhangela umboneleli we-gravity die casting, i-wave yokuqala yolwazi idla ngokuba ludonga olufanayo. Yonke iwebhusayithi inomgangatho ophezulu, ukuchaneka, kunye namashumi eminyaka yamava. Kulula ukufumana umbono wokuba inkqubo-yokugalela isinyithi esinyibilikisiweyo kwisingundo sentsimbi esinokusetyenziswa kwakhona phantsi komxhuzulane-iqondile kwaye nasiphi na isiseko esinezixhobo sinokuzisa. Ngumgibe wokuqala lowo. Umahluli wokwenene ayingomatshini; lulwazi oluqokelelweyo, oluhlala lungathethi, lolawulo lwe-thermal, ukuziphatha kwe-alloy, kunye noyilo lwezixhobo olwahlula inxalenye esebenza kwindawo egqwesileyo. Ndibone iiprojekthi ezininzi zizinzile kuba umthengi ugxile kuphela kwixabiso leyunithi kunye nexesha eliphambili, ephatha inkqubo njengempahla yorhwebo. Ayiyo.
Umbono ongeyiyo ongundoqo: Yinto nje yokungunda
Abantu bacinga ukuba i-gravity die casting ilula kuba ingcamango injalo. Unobumba bentsimbi, uyagalela, upholile, uyakhupha. Kodwa umtyholi ukuloo dynamics yobushushu. Ulawula njani ubushushu kwifa ukunqanda ukuqina kwangaphambi kwexesha kumacandelo amancinci okanye i-porosity kubaphathi abakhulu? Oku akusonjululwa ngencwadana; isonjululwe ngumenzi wepateni kunye nenjineli eyisiseko ebone iinguqu ezilikhulu. Ndikhumbula iprojekthi yecandelo lezixhobo zaselwandle kwi-aluminium-silicon alloy. Iisampulu zokuqala ezisuka kumboneleli omtsha zinezivalo ezibandayo ezingaguqukiyo kubuso obutywiniweyo obubalulekileyo. Isisombululo sabo yayikukunyusa ubushushu obuthululwayo, nto leyo eyadala iingxaki zokuncipha kwenye indawo. Ulungiso lokwenyani, esithe sahlala kulo emva kweebhetshi ezimbini ezisileleyo, yayiyindibaniselwano yokulungelelanisa ijometri yesango kunye nokongeza iziteshi ezithile zokupholisa ekufeni. Incwadana yomthengisi ithe baqhubele phambili ukulinganisa i-thermal, kodwa usetyenziso olusebenzayo lwalubambekile.
Apha kulapho umnombo wokwenene womthengisi ubonisa khona. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ukukhankanya iminyaka engama-30 ekubunjweni nasekusebenzeni luphawu, kodwa kufuneka umbe. Iminyaka engamashumi amathathu ithetha ukuba batyhutyhe ukudodobala koqoqosho, ukunqongophala kwezinto, kunye nokuvela kweemfuno zabaxumi. Loo nkumbulo yeziko sisixhobo sokunciphisa umngcipheko. Mhlawumbi baye babona okwenzekayo xa uqhuba ibakala elithile lentsimbi ye-ductile kwi-gravity die mold eyenzelwe intsimbi engwevu. Loo vimba weenkcukacha uxabiseke kakhulu.
Ukukhethwa kwezinto eziphathekayo ngomnye umaleko. Umxhuzulane wokuphosa awenzelwa ialuminiyam kuphela. Ngelixa i-aluminiyam kunye ne-alloys yayo ixhaphakile, inkqubo ikwasetyenziselwa i-magnesium, i-alloys esekwe kubhedu, kunye nezinye iintsimbi ezityhidiweyo. Umboneleli onogxininiso lwemathiriyeli emxinwa unokuzama ukunyanzela ialloyi ukuba ibe yinkqubo engayilungelanga. Ubuchwephesha obudweliswe kwi-QSY kwinsimbi engenasici kunye ne-alloys ezikhethekileyo ezifana ne-nickel-based based cebisa ukuqhelana ne-high-melting-point, izinto ezinomngeni. Oku kuthetha ukuba indlela yabo yoyilo lokufa kunye nolawulo lobushushu lwakhiwe kuluhlu olubanzi, olufuna kakhulu lweemeko kunevenkile eyenza kuphela i-aluminiyam ye-A356. Linqanaba elahlukileyo letekhnoloji yesithando somlilo, isayensi yezinto ezifayo, kunye nolawulo lwenkqubo.
Apho Ukudityaniswa koMatshini akuKhethekanga
Nasi isifundo esisetyenzwe nzima: ungaze wahlule umboneleli otyhidiweyo kumthengisi womatshini weendawo ezinyamezelayo. I-handoff phakathi kwe-casting kunye ne-CNC machining ngumhlaba ochumileyo wokukhomba ngeminwe. Ukuba inxenye ye-as-cast inokuphazamiseka okuncinci okanye ubuso obunzima bedatum abufumanekanga ngokufanelekileyo, umachini ushiywe ukuba abuyekeze, ehlala esitya kwizinto ezibonakalayo okanye edala ubukhulu bodonga olungalinganiyo. Ndikhe ndakwintlanganiso apho i-caster igxeka ukulungiswa kwe-machinist, kwaye i-machinist igxeka ukungaguquki kwe-caster. Yinkcitha xesha nemali.
Umboneleli odibeneyo othe nkqo, olawula zombini umxhuzulane die casting kunye nelandelayo CNC machining phantsi kophahla olunye, kuphelisa oku. Iqela labo lomatshini libonelela ngengxelo ngqo kwiqela labo labasunguli. Banokuyila ukuphosa kunye nokulungiswa komatshini engqondweni ukusuka kusuku lokuqala. Ukujonga imodeli ye-QSY-apho badwelisa ngokucacileyo zombini ukuphosa (igobolondo, utyalo-mali) kunye nomatshini we-CNC njengeenkonzo eziphambili-oku kulungelelaniswa kuhambelana. Kwinxalenye yokuphoswa komxhuzulane, oku kuthetha ukuba banokubeka idrafti ngobuchule, bahlengahlengise ubukhulu bodonga, kwaye bafumane imigca yokwahlulahlula kungekuphela nje ukwenza kakuhle, kodwa ukuqinisekisa ukuba inxalenye ihleli ililitye eliqinileyo kwi-CNC vise amanyathelo amahlanu kamva. Ukongiwa kweendleko kunye nokuqinisekiswa komgangatho koku kukholisa ukujongelwa phantsi kuthelekiso lwe-RFQ.
Sasineprojekthi yolwakhiwo lwezindlu zegearbox apho umthengisi wokuqala wazisa iicastings ezintle ezigqithise zonke iitshekhi ezinobungakanani. Kodwa ngexesha lomatshini, i-flange enodonga olucekeceke yayiza kuthetha ngenxa yokuba i-ribbing yangaphakathi, eyenzelwe ukuzinza, yenza i-harmonic engalinganiyo ngexesha lokusika. Umnikezeli odibeneyo ebeya kubamba oko kwinqanaba lokulinganisa. Siye satshintshela kwiqabane elinazo zombini izakhono, kwaye bayila ngokutsha ipateni yeembambo ngegalelo elivela kumatshini wabo wokukhokela. Umjikelo wesibini umzobo owenziwe ngoomatshini njengebhotolo. Isifundo sasicacile: inkqubo yinkqubo eqhubekayo, hayi uthotho lweenkonzo ezifihliweyo.
Ingxoxo yeZixhobo: UVavanyo lweNtsebenziswano
Isibophelelo sokuqala esikhulu sezemali kunye nobugcisa kunye nomboneleli we-gravity die casting sisixhobo-umda ngokwawo. Apha kulapho ubona khona ukuba umthengisi ungumthathi-odolo okanye iqabane. Umthengisi olungileyo uya kucela umngeni kuyilo lwakho. Baza kubuza malunga neendlela zomthwalo ezicetywayo, bacebise ukongeza irediya ongakhange ucinge ukuba iyimfuneko, okanye bacebise ukuhambisa umgca wokwahlula ukuphucula umphezulu ogqityiweyo kubuso bobuhle. Umntu onamava kancinci uya kucaphula kanye loo nto uyithumelayo, rhoqo ngexabiso eliphantsi lesixhobo, ukuseta iindleko eziphezulu kwinxalenye nganye kunye nemiba yokuthembeka ezantsi emgceni.
Ingxoxo kufuneka ibe yezobugcisa kunye neenkcukacha. Leliphi ibakala lentsimbi ye-H13 abayisebenzisayo xa befa? Ithini inkqubo yabo yonyango lomphezulu (i-nitriding, njl.) yokumelana nokukhukuliseka komhlaba? Buthini ubomi babo obulindelekileyo bokufa kwi-alloy yakho ethile? Iimpendulo zabo zityhila indlela ababecinga ngayo ixesha elide. Isicwangciso somthengisi wemveliso ye-100,000-shot iya kwakha kwaye igcine isixhobo ngokuhlukileyo kunokulindela i-10,000 shots. Ndenze impazamo yokuhamba nesicatshulwa esisezantsi sesixhobo. Ukufa kubonise ukuguga emva kwemijikelo ye-15,000, ebangela ukunyuka kwe-flash kunye ne-dimensional drift, kunye neendleko zokuhlaziya kunye nexesha lokuphumla licime naluphi na ugcino lokuqala.
Le yenye indawo apho amava abanzi enkampani, njengomsebenzi we-QSY notyalo-mali kunye nokubumba iqokobhe, inokuba yinzuzo engathanga ngqo. Ezo nkqubo zifuna ukuchaneka okugqithisileyo kwipateni kunye nokwenza umngundo. Eso siko lokuchaneka kunye nengqalelo kwiinkcukacha zezixhobo kusenokwenzeka ukuba kungene umxhuzulane wokuphosa umsebenzi wabo ngokunjalo. Xa undwendwela indawo yabo ku tsngtaocnc.com, ugxininiso alukho koomatshini bokujula kuphela, kodwa kwi-ecosystem epheleleyo—ukususela kuhlalutyo lwezinto eziphathekayo ukuya kwinxalenye egqityiweyo yomatshini. Icebisa ukuba isixhobo sibonwa njenge-asethi enkulu kwinkqubo yemveliso enkulu, hayi into enokulahlwa.
Xa ii-alloys ezikhethekileyo zitshintsha uMdlalo
Uninzi lwentetho yokuphosa i-die casting ijikeleze i-aluminiyam. Kodwa xa i-spec yakho ibiza i-nickel-based okanye i-cobalt-based superalloy yobushushu obuphezulu okanye indawo ezonakalisayo, yonke into ikhula ngobunzima. Iqondo lobushushu lokunyibilika liphezulu, intsimbi ayinalwelo oluncinci, kwaye iyasebenza ngakumbi ngezinto zokufa. Umda wempazamo ucutheka kakhulu. Umthengisi obanga isakhono apha kufuneka abonakalise ngaphezu kwesithando somlilo esinokufikelela kubushushu.
Imalunga ne-atmosphere elawulwayo enyibilikayo ukunqanda i-oxidation, ukufudumeza okuchanekileyo kwangaphambili kwefa kwifestile ethile (ibanda kakhulu kwaye ufumana i-mistruns, ishushu kakhulu kwaye ufumana i-soldering / sticking), kunye neengubo ezikhethekileyo ezihlala zikhethekileyo kumngxunya wokufa. Iindlela zokungaphumeleli ziyabiza. Sakhe sazama i-high-nickel alloy component. Umthengisi wokuqala, ongenamava ngezinto eziphathekayo, akazange alawule ngokwaneleyo ubushushu bokufa. Amalungu adityaniselwe kwidiyiti, efuna ukususwa okutshabalalisayo kunye nokuphinda kusetyenzwe ngokupheleleyo. Iprojekthi yalibaziseka ngeenyanga.
Ukubona i-alloys ezikhethekileyo ezidweliswe ngumthengisi onjenge-QSY yindawo enentsingiselo yedatha. Ibonisa ukuba kusenokwenzeka ukuba batyale imali kwizixhobo ezincedisayo kwaye, okona kubaluleke kakhulu, baphuhlise ulwazi lwenkqubo yokuphatha ezi mathiriyeli zinzima. Kumthengi, oko kuthetha ukuba iprojekthi yakho yangoku ikwi-aluminiyam eqhelekileyo, iinkqubo zalo mthengisi mhlawumbi zenziwe ngobunjineli obungaphezulu kwiimfuno zakho-yinto entle leyo. Ithetha isiseko esiphezulu solawulo kunye nomngcipheko ophantsi wokusilela kwenkqubo yentlekele. Imbali yabo yeminyaka engama-30 ibonisa ukuba banexesha lokufunda ezi zifundo, mhlawumbi ngendlela enzima, kunye nokwakha iinkqubo ezomeleleyo.
Isiphelo Sokufunyanwa Kwezinto Zokwenene
Ngoko ke, ukhetha njani? Ujonge ngaphaya kwezihloko zentengiso. Uphonononga ingxoxo yobugcisa ngexesha lesigaba sokucaphula. Ucela ukhenketho lwenkqubo yabo yohlalutyo lokusilela. Ucela ukuthetha nomyili wabo wezixhobo kunye nomphathi wabo womgangatho, hayi injineli yokuthengisa kuphela. Ucela uphononongo kumacandelo angaphumelelanga ekuqaleni kunye nendlela azisombulule ngayo.
Eyona nto ifanelekileyo umxhuzulane die casting umboneleli isebenza njengolwandiso lweqela lobunjineli bakho. Bazisa iimbono zokwenziwa kwitafile phambi kokuba uyilo lube ngumkhenkce. Baselubala malunga nezithintelo zabo. Ixabiso labo alikho nje ekwenzeni imilo, kodwa ngokuqhubekayo ukwenza icandelo elisebenzayo, elithembekileyo, nelinobuchule ukusuka kwizinto ezifanelekileyo, kunye neendleko ezipheleleyo zobunini ezivakalayo. Lumanyano olwakhelwe kulwimi lobugcisa olwabelwanayo kunye nokuqondana ukuba inkqubo ekhangeleka ilula intsonkothile ngokukhohlisa.
Ekugqibeleni, ubomi obude bomthengisi kunye nomnikelo wenkonzo odibeneyo, njengoko kubonwa kunye namaziko afana ne-QSY, ahlala ehambelana nobu nzulu. Ayisosiqinisekiso, kodwa sisihluzo esomeleleyo. Icebisa ukuba bajonge imigibe, iilophu zengxelo ezidityanisiweyo phakathi kokusakha kunye nomatshini, kwaye bavela ngaphaya kokuba yindawo nje esisiseko ukuze babe ngumboneleli wesisombululo soveliso. Lolo luhlobo lweqabane elijika umzobo kwiscreen kwibhokisi yamalungu agqibeleleyo, ukuthunyelwa emva kokuthunyelwa, ngaphandle kwedrama. Kwaye kwimveliso, akukho drama yeyona nto inconywayo.
