Xa ubona i-'Precision Casting Pvt Ltd' kwigama lenkampani, kulula ukwenza uqikelelo. Abaninzi bacinga ngokukhawuleza ngokunyamezela okuphezulu, iinxalenye ezintsonkothileyo, zihlala zinxulumanisa ngokukodwa nokufakwa kotyalo-mali. Ayonto iphosakeleyo, kodwa ayiphelelanga. Ulwakhiwo lwe-'Pvt Ltd' luxhaphakile kwimimandla emininzi yokufumana imithombo, kodwa ayikuxeleli nto ngobunzulu besakhono. Ndikhe ndazibona iivenkile ezinelo gama ziqhuba amashumi eminyaka ubudala imigca yesanti eluhlaza yokuphosa ngokurhabaxa, kunye nezinye ezisebenza ngomgangatho we-vacuum induction yokunyibilika kunye neenkqubo zokubumba iqokobhe kumacandelo e-aerospace. Isitshixo ayisosihloko; bubuchule benkqubo emva kwayo. Oku kungacaci kulapho ukukhangela kudla ngokukhubeka-ukucinga ukuba ukuchaneka kunikiweyo kunesiphumo esiqinisekisiweyo sobuchule kunye nolawulo oluthile.
Undoqo: Imalunga neNkqubo, hayi nje isithembiso
Ukuphosa okuchanekileyo, kum, kuxhomekeke kwinkqubo yophindaphindo. Sithetha ngeepateni kunye nokubumba. Inkqubo yokubumba iqokobhe, okanye inkqubo ye-Croning, yinto esebenzayo ye-medium-volume, intsimbi enzima kunye ne-alloy parts. Inika umphezulu ongcono wokugqitywa kunye nokuchaneka komda kunokuphosa isanti, kodwa ayisiyiyo incopho. Apho ungena khona ngokwenene kwindawo echanekileyo kukuphosa utyalo-mali, indlela elahlekileyo ye-wax. Kulapho iimpahla ze-'Pvt Ltd' zizahlula khona. Ukukwazi ukulawula i-ceramic slurry, i-stuccoing, i-parameters yesithando somlilo, kunye nokuthululwa kokugqibela-yiokhestra. Ukuphambuka okuncinci kwiqondo lokushisa langaphambi kobushushu beqokobhe leceramic kunokukhokelela kwi-mistruns okanye iinyembezi ezishushu kumacandelo amancinci. Yinkqubo endiyibonileyo ukuba ilawulwa ziingcali ekudala zikho, hayi iingcali ngokubanzi.
Umzekelo, qwalasela izixhobo ezifana ne-CF8M engenasici okanye iintsimbi ezimbini. Ukugalela ezi kulungiselelo lotyalo-mali kufuna ulawulo oluluqilima kumazinga okuqinisa ukuthintela ukwakheka kwesigaba esicimayo. I-Foundry inokudwelisa ezi zixhobo, kodwa inkxaso yazo ye-metallurgical-nokuba benza uhlalutyo lwe-spectro yangaphakathi, indlela abayila ngayo inkqubo yabo yokungena kwezi ngxube-yeyona nto ixelayo. Ndikhumbula iprojekthi yecandelo levalve yolwelo oludlekayo apho i-spec yabiza umxholo ongqongqo we-ferrite. Ababoneleli abaninzi be-'Precision Casting' bayithembisile, kodwa inye kuphela enesixhobo sokulinganisa i-Fischer esinokubonelela ngeecerts ngebhetshi nganye, ebonisa ulawulo olungaguqukiyo.
Kulapho imbali yenkampani iba yinto ebonakalayo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ephawula ngaphezu kweminyaka engama-30 ekubunjweni nasekusebenzeni, icebisa ukuguquguquka kwemijikelo yenkqubo. Badwelisa ukungunda kweqokobhe kunye nokuphosa utyalo-mali ngokukodwa. Ngumnikelo ogxininisiweyo lowo. Ubude beminyaka engama-30 buthetha ukuba kusenokwenzeka ukuba baye baphinda-phinda ngokuvela kwepateni yezinto-ukusuka kwiplanga ukuya kwi-aluminiyam ukuya kwii-resin zeprototyped ezikhawulezayo-kwaye baye bajongana nezinto ezicuthekayo nganye. Olo lwazi lweziko malunga nendlela ipateni ye-wax eqhuba ngayo ngokuchasene ne-polymer eprintiweyo ye-3D ayikho kwincwadi yokufunda; ikwinkqubo yabo yezigodo.
Ibhulorho ebalulekileyo: Ukudibanisa ukuCasa kunye neMachining
Nanku umqobo omkhulu: ukuphatha ukuphosa kunye nomatshini njengeesele ezahlukeneyo. Indawo echanekileyo ephoswe ngokucokisekileyo ihlala ikufutshane ne-net-shape, kodwa isoloko ifuna ukwenziwa ngomatshini wokutywina umphezulu, imisonto, okanye iibhore ezinyamezelayo. Ukuba umboneleli wokuphonononga akakulawuli umatshini, ufumana ilifa lomngcipheko omkhulu wolungelelwaniso. Umchwephesha unokufumana indawo enzima kwingqele engalindelekanga kwi-casting, okanye utshintsho oluncinci olushiya isitokhwe esingonelanga kwi-flange ebalulekileyo. Umdlalo wetyala uqala.
I-machining ye-CNC edibeneyo ayinakuxoxisana kumacandelo abalulekileyo. Xa indlu yokuphosa nayo isenza umatshini, banokucwangcisa inkqubo yokuphosa kunye ne-machining datum engqondweni. Banokongeza isitokhwe kanye apho sifuneka khona kwaye basinciphise kwenye indawo. Ukukhankanywa okucacileyo kwe-QSY komatshini we-CNC ecaleni kweenkonzo zabo zokuphosa luncedo olukhulu ekusebenzeni. Oku kuthetha ukuba banokwenza uhlolo olulungelelanisiweyo lomatshini wokulinganisa (CMM) kwakwindlela efanayo yokuseta esetyenziselwa ukwenza oomatshini, beqinisekisa ukuba inxalenye yokugqibela ihambelana noshicilelo olusuka kumthombo omnye woxanduva. Ndiye ndaphicotha izibonelelo apho olu hlanganiso lungenamthungo; iseli yokugalela ukugqiba ukutya ngqo kwibhanki CNC amaziko machining nkqo, kunye nabahambi inkqubo ezibandakanya zombini ukuphosa amanani ubushushu kunye nezigodo machining isixhobo offset.
Umzekelo osebenzayo wawuyi-pump impeller kwi-alloy-based alloy (cinga i-Inconel 718). Ukuphosa kufuna ingqibelelo kwizantya eziphezulu ezijikelezayo, kodwa iprofayili ye-hydraulic ye-vanes idinga i-CNC milling ukufezekisa umphezulu ofunekayo kunye nokunyamezela iprofayili. Ukukhangela usasazo kwenye 'Precision Casting Pvt Ltd' kunye nomatshini ukuya kwenye kwazisa ukulibaziseka kweeveki ezintandathu ngenxa yokungahambelani komgangatho. Isifundo sasicacile: ixabiso likudibaniso oluthe nkqo. Iwebhusayithi yomthengisi ku https://www.tsingtaocnc.com ibonisa oku kukwazi kudityanisiweyo, okuxela ngakumbi kunegama legeneric.
IiNuances zeMathiriyeli: Inyani ye-Special Alloys
Ababoneleli abaninzi badwelisa 'iialloyi ezikhethekileyo' kwiphepha labo lezakhono. Ligama elibanzi elinokuthetha nantoni na ukusuka kwintsimbi ye-4140 elungisiweyo ukuya kwii-superalloys eziyinyani. Ukuphathwa kwe-cobalt-based (umzekelo, i-Stellite) okanye i-nickel-based alloys (efana ne-Monel) i-ligi eyahlukileyo ukusuka kwiintsimbi eziqhelekileyo ezingenasici. Ezi zixhobo zihlala zi-viscous, zithande ukukrazuka okushushu, kwaye zifuna amaqondo obushushu athile okugalela kunye nokufudumeza komngundo kwangaphambili.
Umceli mngeni kwezi asikokunyibilika nje; lulungiselelo lonke. Iipateni zewax zokwenziwa kotyalo-mali kwezi ngxubevange zihlala zifuna isango elikhethekileyo ukuqinisekisa ukuqina. Imathiriyeli yeqokobhe inokufuna isiseko esahlukileyo esiphikisayo, njenge-zircon, ukumelana namaqondo obushushu aphezulu okugalela kunye nokuthintela ukusabela kokungunda kwesinyithi. I-Foundry eyazi ngokwenene le nto iya kuba nemigca yesitofu esahlukileyo kunye namagumbi okwakha iqokobhe kwezi ngxubevange ukunqanda ungcoliseko. Xa ndibona inkampani efana ne-QSY ibiza ngokucacileyo i-cobalt-based kunye ne-nickel-based alloys, ibonisa iziseko ezinikezelweyo. Asiyonto udlala kuyo; Ixabiso lenkunzi yelayini yesithando somlilo esifanelekileyo kunye nolawulo longcoliseko lokunyibilikisa ezi zixhobo ziphezulu kakhulu.
Ukungaphumeleli kudla ngokuvela ekuphatheni njengentsimbi eqhelekileyo. Ndikhumbula umboniso oqhutywayo wecandelo le-iturbine yokutywina apho ingxubevange ye-cobalt yayigalelwe kwiqokobhe elisemgangathweni elisekelwe kwi-silica elilungiselelwe ukucoceka. Isiphumo yaba kukusabela okumandundu komphezulu kunye nokukalwa, okwathi emva koko kwabangela ukusilela kwintlekele ngexesha lomatshini njengoko isixhobo sibetha umaleko ongcolisekileyo. Oyena nobangela ibiyinkqubo enqumlayo. Ingcaphephe ayinakuze yenze loo mpazamo yosetyenziso olunqamlezileyo.
Umphezulu wokuGqibela kunye neeSango ezinoMda: IiMetrikhi zokwenyani
Ukuchaneka kulinganisiwe. Ekuphoseni, imalunga nemigangatho yeCT (Cast Tolerance) kunye noburhabaxa bomphezulu (Ra). Ireferensi yoshishino eqhelekileyo ngumgangatho we-ISO 8062 CT. Ivenkile ebanga 'ukuchaneka' kufuneka ikwazi ukukuxelela ukuba leliphi inqanaba le-CT abasoloko belibamba ngesayizi kunye nenkqubo enikiweyo. Ukuphosa utyalo-mali, i-CT 4-6 iqhelekile kwimilinganiselo emininzi. Ukubamba i-CT4 kwindawo enzima luphawu lolawulo oluphezulu.
Ukugqitywa komphezulu yenye isiphiwo. As-cast surface ukusuka kwiqokobhe eliphezulu okanye inkqubo yotyalo-mali inokufikelela kwi-Ra 3.2 μm okanye ngcono. Kodwa kufuneka ubuze: ngaba lixabiso eliqhelekileyo okanye eyona meko? Kwaye kweyiphi ijometri? Umphezulu osicaba kulula; umphezulu wangaphakathi we-diameter encinci, isicatshulwa esigobileyo luvavanyo lwangempela. Kulapho kubalulekile ukuzibonela ngawakho amehlo. Ngexesha lotyelelo loncedo, ndihlala ndicela ukubona iinxalenye ezingaphakathi kwinkqubo kunye neengxelo zokuhlola ukuze zigqitywe kwiifitsha zangaphakathi. Amanani akwingxelo kufuneka atshatise i-tactile ne-visual feel of the part.
Iinkampani ezininzi 'zePrecision Casting' zisilela kumaxwebhu angaguqukiyo. Banokwenza isampuli enye elungileyo, kodwa ingxelo yokuhlola inqaku lokuqala kunye nesicwangciso solawulo lwenkqubo yokwenziwa kwemveliso yinto ebalulekileyo. Umsebenzisi osemthethweni uya kuba nokuhamba okucacileyo komsebenzi: i-wax assembly -> inqaku lokuqala lokukhangela i-dimensional -> isakhiwo seqokobhe -> ukuhlolwa kweqokobhe kwangaphambili -> ukugalela -> ukunkqonkqoza -> ukunqunyulwa -> ukuhlolwa kokugqibela komgangatho kunye nokubonwayo. Inyathelo ngalinye kufuneka libe neendawo zokukhangela. Ukungabikho koku kuhamba okubhaliweyo yiflegi ebomvu, kungakhathaliseki ukuba yiyiphi inkampani ebizwa ngokuba yinkampani.
