Xa usiva 'utyalo-mali lwe-OEM,' umfanekiso ongoko nangoko udla ngokuba ngongenasiphako, izinto ezinokwakheka komnatha ziqengqeleka kumgca ococekileyo. Yeyona nto ifanelekileyo yokuthengisa. Inyani, leyo ufunda kuphela ngokubamba iqokobhe elishushu okanye ukuphikisana ngengxelo yeCMM, imbi. Yinkqubo echazwa kakhulu ngamandla ayo okuchaneka njengoko inenkani, imiqobo esebenzayo-uyilo lokungena olujongeka lugqibelele ekufaniseni kodwa lubangela ukushwabana ekoneni, ukungaguquguquki kwealloyi ukusuka kubushushu ukuya kubushushu, okanye uqoqosho olulula, olukhohlakeleyo lwe-amortization yezixhobo zeprojekthi ye-OEM yexesha elifutshane. Abathengi abaninzi, kwanabo banamava, balungisa iicerti zezinto eziphathekayo kunye nengxelo ebanzi, ebalulekileyo, ungandivi kakubi. Kodwa ngamanye amaxesha bayaphoswa yinkqubo yobungcali evala umsantsa phakathi kwemodeli yeCAD kunye nebhokisi yeengxenye ezilungileyo. Kulapho umsebenzi wenene usenzeka khona.
ISiseko: Iqala (kwaye Isoloko Ikhubeka) ngePateni
Wonke umntu uyazi ukuba ufuna ipateni elungileyo. I Ukuphosa utyalo-mali lwe-OEM inkqubo yakhiwe ngokoqobo ngeenxa zonke kuyo. Kodwa 'ulungile' ligama elilula ngenkohliso. Kwiprototype okanye ukubaleka kwamaqhekeza angamashumi amahlanu, iwax eyenziwe ngoomatshini okanye ipateni yeresin ye-SLA inokuba litikiti elikhawulezayo. Yinto esiyenzele umxhasi ophuhlisa ibhloko ye-bespoke hydraulic manifold block kulo nyaka uphelileyo. I-CAD yavunywa, sayilungisa i-wax, kwaye iiprototypes zokuqala zibukeka zihle. Umba wavela kamva: iwax eyenziwe ngoomatshini yayinamanqaku achuliweyo esixhobo atshintshela kwiqokobhe leceramic, idala ukunyuka koxinzelelo. Kwimveliso eqhutywa ngamawaka, loo ndlela iphambene ngokwezimali nangobugcisa. Udinga ukufa kwentsimbi eqinile, kwaye kulapho intsebenziswano iqala khona ngokwenene.
Ndikhumbula ndisebenza neqela lobunjineli I-Qingdao Qiangsenyuan Technology (QSY) kwi-impeller yensimbi engenasici. Ingcebiso yabo, ezalwe ukusuka kumashumi eminyaka iqokobhe ngundo ukuphosa kwaye utyalo mali, yayikukulungisa ii-engile zethu zedrafti ngesiqingatha nje sedigri ngaphezu komgangatho. Yayibonakala incinci, iphantse yahamba. Kodwa inqaku labo lalimalunga nobomi bokufa kunye nokuhambelana kwepatheni ye-wax ejection. Eso siqingatha sesidanga sinciphise ukuncamathelwa kwewax kunye nokunciphisa ukunxitywa kwe-wax ngaphezulu kwemijikelo ye-100,000, kuthintela ukukhukuliseka kancinci kwimilinganiselo ebalulekileyo yencakuba. Yayisisifundo ekuyileni inkqubo, hayi nje umsebenzi.
Esi sigaba kulapho isihluzo esikhulu sokuqala sisetyenziswa kwi OEM iprojekthi. Ukuba umthamo wonyaka awuthetheleli utyalo-mali lwezixhobo ezintlanu, sele ukwixabiso elahlukileyo kunye nomgangatho weparadigm. Urhweba ngeyona ndlela iphezulu uzinzo ukuze ube bhetyebhetye. Lukhetho olusebenzayo, kodwa kufuneka lube lolulolwazi, nolindelo olusekwe ngokufanelekileyo kumahluko aphezulu kancinane okanye ukucoca emva kokuphosa.
I-Alloy Maze: I-Specs, iNyaniso, kunye ne-Special in Special Alloys
Amaphepha okukhetha izinto eziphathekayo sisiqalo, ayisosiqinisekiso. I-316L ayinastainless yi-316L, akunjalo? Hayi ncam. Isenzo sokunyibilika, inkqubo ye-deoxidation, i-trace element control-ezi zichaza ukusebenza kwehlabathi lokwenyani. Kuninzi lwezicelo zorhwebo, ukunyibilika okusemgangathweni kwi-Foundry ethembekileyo kulungile. Kodwa siye saba neeprojekthi, njengendlu yesivamvo yenkqubo yeekhemikhali zobushushu obuphezulu, apho umgangatho we-316L osuka kumatshini wokusila usilele kwangaphambi kwexesha ngenxa ye-intergranular corrosion.
Kulapho iqabane elinobunzulu be-metallurgical libaluleka kakhulu. QSYamava nge ialloys ezikhethekileyo njenge-nickel-based kunye ialloys esekwe cobalt kwangena umdlalo. Abazange bagalele nje i-spec; bacebise i-316L elungisiweyo kunye nolawulo olungqongqo kwikhabhoni kunye ne-nitrogen eyongeziweyo. Iindleko ngekhilogram ziye zanyuka, kodwa inxalenye yobomi yanda. Icala le-flip yi-nightmare yokuchaza i-alloy engaqhelekanga kakhulu yendawo epholileyo kuba ivakala yomelele. Ndibone iinjineli zicacisa i-Inconel 718 ngenxalenye yokubona i-400 ° C kunye noxinzelelo oluncinci-i-overkill enkulu ephindwe kathathu ixabiso leqhekeza. Inkqubo yokuphosa inokusingatha, kodwa ibhajethi yakho mhlawumbi ayikwazi.
Umceli mngeni ngezi ngxubevange eziphezulu zokusebenza kwi utyalo mali kukuziphatha kwabo ngexesha lokuqina. Ngokuqhelekileyo bathanda ukukrazula okushushu okanye i-micro-porosity. Inyanzelisa intsebenziswano kwinxalenye yejometri. Unokufuna ukongeza amancinci, iimbambo zedini okanye uguqule utshintsho lwecandelo ukuze uqinisekise ukuqina kwesikhokelo, apho isebe lomatshini liyakususa kamva. Ifiphalisa umgca phakathi koyilo lokuphosa kunye CNC Machining ucwangciso, yindlela ekufanele ukuba ngayo.
Iqokobhe: Apho iiCeramics zidibana khona noBugcisa
Inkqubo yokwakha iqokobhe yintliziyo yendlela, kwaye yeyona nxalenye izenzekelayo. Luthotho lweediphu, istuccos, kunye nokoma. Ithiyori ilula; ukuhambelana kunzima. Ukufuma ngemini kuchaphazela amazinga okomisa. I-viscosity ye-slurry idinga ukubeka iliso rhoqo. Iqokobhe elibuthathaka liza kuqhekeka ngexesha le-dewaxing (ukuqhuma kweqokobhe elidumileyo), ngelixa elityebileyo linokumelana nokuzaliswa kwesinyithi okanye kubangele iziphene zokuncipha.
Oku sikufunde ngokusilela. Ibhetshi yezibiyeli ezintsonkothileyo zentsimbi zinemingxuma eqhubekayo. Iinkcazo ezinobungakanani ziye zabethwa, kodwa ukugqiba kwakungamkelekanga. Umoni? Ukungangqinelani kobungqingqwa bedyasi eludaka oluphambili ngaphezu kweempawu zangaphakathi ezintsonkothileyo. I iqokobhe ngundo ukuphosa ubuchwephesha kwi-Foundry, kule meko hayi QSY kodwa omnye umthengisi sasisebenzisa ngaphambili, wayengekho nzulu ngokwaneleyo ukuba inxalenye ubunzima. Isisombululo sasibandakanya ukuyila ngokutsha umthi wokudityaniswa kwe-wax ukuze ubonise ezo ndawo kwi-engile engcono yokugquma kunye nokulungelelanisa ubungakanani bemathiriyeli yestucco kwidyasi yokuqala. Yongeza usuku kumjikelo wokwakha iqokobhe kodwa igcine yonke ibhetshi.
Le yindawo apho ugweba i-Foundry kungekhona ngencwadana yayo, kodwa ngokucoceka kwegumbi layo le-slurry kunye nedatha yedatha yamagumbi ayo omisa. Ulawulo apha luyinto yonke.
Ukusuka kwi-Rugh Casting ukuya kwiNdawo eGqibelelweyo: Ukuxhawulana kwesandla ngoMachining
Hayi Ukuphosa utyalo-mali lwe-OEM Inxalenye iyimilo enetha ngokwenyani. Uhlala unokususwa kwesango, ukugaya, ukudutyulwa kokudubula, kwaye phantse rhoqo, ezinye CNC Machining yeempawu ezibalulekileyo. Esi sesona sixhobo sinzima kakhulu. Ukuphosa okunikezelweyo okunikezelweyo okungahambelaniyo kwesibonelelo sesitokhwe okanye ukungaguquguquki kakuhle kwedatha kuguqula ukuchaneka okuchanekileyo kube yiphupha elibi lomatshini, licima lonke ugcino lweendleko.
Eyona nto ifanelekileyo, ezithandwa ziinkampani QSY qulathe ngokunikezela ngokudibeneyo ukuphosa kunye nomatshini, kukuba neqela elingumatshini elibandakanyekayo kuyilo lokuqala lomdlalo. Iza kubanjwa phi? Yeyiphi imiphezulu eyenziwe ngoomatshini kwaye yeyiphi eshiywe i-cast? Isango lokungena kufuneka lilungiselelwe kungekuphela nje ukuqukuqela kwentsimbi evakalayo kodwa kwanokuba libekwe kwindawo eza kukhutshwa ngoomatshini kamva, kungashiyi bungqina. Ndizibonile iiprojekthi apho i-Foundry kunye nevenkile yomatshini yayingamaqumrhu ahlukeneyo, ekhomba iminwe phezu kolungelelwaniso olungalunganga lwe-0.5mm. Imodeli edibeneyo iyayinqanda loo nto. Oomatshini babo banokuphendula kwivenkile yabo yepateni: Yongeza i-0.2mm yesitokhwe apha kuba isixhobo sethu sithande ukuphambuka, sisenza umjikelo olungileyo wophuculo.
Kwicandelo leemoto ezinomthamo ophezulu esisebenze kuwo, oku kudityaniswa kwabavumela ukuba bayile i-casting edibeneyo kunye ne-machining fixture. I-casting iqiniswe ngendlela eyakha iindawo zendalo ze-CNC op yokuqala, ukunciphisa ixesha lokucwangcisa nge-70%. Kulapho okwenyani OEM ixabiso livuliwe-kwixabiso lilonke ngenxalenye elungele ukuhlohla, hayi nje ixabiso lokusalwa ekrwada.
Inyani yoRhwebo: iNtsebenziswano vs. Intengiselwano
Okokugqibela, eyona mpazamo inkulu kukunyanga Ukuphosa utyalo-mali lwe-OEM njengentengiselwano elula yokuthenga. Lubudlelwane bobugcisa, obuhlala buhlala ubomi bemveliso. I-RFQ ecela nje ixabiso ngeqhekeza ngalinye ngokusekelwe kwimodeli ye-3D icela ingxaki, okanye ubuncinane kwiindleko ezifihliweyo kunye nokulibaziseka kamva. Isicatshulwa esinentsingiselo siza emva kophononongo lweDFM (uYilo lokuVeliswa).
Iqabane elilungileyo, elinomsebenzi wexesha elide njengembali ye-30 yeminyaka ekhankanywe ngu QSY, iya kubuza imibuzo enokuthi ingabikho: Ngaba singakwazi i-radius le kona yangaphakathi ebukhali? Ngaba olu donga lunokwenziwa lube ngqindilili ngokufanayo? Ngaba inqanaba elahlukileyo, elinokuphoswa ngaphezulu kwe intsimbi engenasici ukuhlangabezana neemfuno zakho? Abazami ukwenza umsebenzi wabo ube lula; bazama ukwenza inxalenye yemveliso, ethembekileyo, kwaye ingabizi. Ukubuyisela umva kuyo yonke ingcebiso yokugcina uyilo lunyulu kudla ngokukhokelela kwindawo engenakulahleka okanye efuna iinzame zobuqhawe kunye neendleko eziphezulu zokuvelisa.
Ezona projekthi ziphumeleleyo endiye ndazilawula zaqala ngendibano yocweyo edibeneyo-abayili, iinjineli zesiseko, kunye noomatshini kwigumbi (okanye kumnxeba omde wevidiyo), bephikisana ngemodeli. Imdaka, iyaphindaphinda, kodwa ilayisha ngaphambili iingxaki. Loo nkqubo, ngaphezu kwayo nayiphi na itekhnoloji enye, yinto echaza impumelelo Ukuphosa utyalo-mali lwe-OEM ikhonkco lokubonelela. Ijika umzobo ube yinxalenye ebonakalayo esebenzayo, ibhetshi emva kwebhetshi, oko kukuthi, ekugqibeleni, eyona nto ibalulekileyo.
