Inkonzo yokuphosa i-wax inika ukuchaneka kobukhulu obungahambelaniyo kumalungu esinyithi asebenza phantsi koxinzelelo olugqithisileyo, ukunxiba, okanye uxinzelelo lobushushu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sivelise ngaphezulu kwe-12,000 yamacandelo otyalo-mali ukusukela ngo-2018-nganye ilandeleka kwibhetshi yezinto ezikrwada, umjikelo wonyango lobushushu, kunye nengxelo yokugqibela yokuhlolwa kweCMM. Oku ayingobuchule bethiyori. Ukwenziwa kwemihla ngemihla kwimizimba yevalvu yehydraulic esebenza kwibhari engama-450, imilomo yengxubevange ye-cobalt ephethe irhasi yokukhupha i-650°C, kunye nezindlu zempompo ezenziwe ngoomatshini ukuya ku-±0.015 mm GD&T callouts.
Kutheni inkonzo yokuphosa i-wax ibalulekile xa ukuchaneka kungaxoxiswana
Ukuphosa utyalo-mali kuqala ngepatheni ye-wax-ngokuchanekileyo ukuphindaphinda inxalenye yokugqibela yejometri. Loo pateni igqunywa ngodaka lweceramic, idityaniswe, ize idutyulwe ibe ngumbumba olungele isinyithi esinyibilikisiweyo. Isiphumo? Iindawo ezikufutshane-netha ezinemilo egudileyo, ukunyamezelana okuqinileyo, kunye neemfuneko zedrafti zero. Kodwa ayizizo zonke iinkonzo zokugalela iwax ezibonelela ngeziphumo ezingaguqukiyo. Siyibona ngokuphindaphindiweyo: abathengi batshintshe ababoneleli emva kokufumana i-castings kunye ne-micro-shrinkage kwiindawo zokutywinwa ezibalulekileyo, ukwakheka okuziinkozo okungahambelaniyo kwiibhetshi ze-AMS 5387, okanye iziphene zomhlaba ezifuna i-30% ngaphezulu kokususwa kwesitokhwe se-CNC kunokuba bekucwangcisiwe.
Unobangela osisiseko awusoloko uphosakele kakubi-kukungalungelelani phakathi kwenjongo yoyilo, ukuziphatha kwezinto eziphathekayo, kunye nolawulo lwenkqubo. Ngokomzekelo, i-T800 i-cobalt-based alloy contracts i-12.4% ngaphezu kwe-316 engenasici ngexesha lokuqina. Inkonzo yokugalela iwax ngaphandle kweelophu zemetallurgical iya kuvelisa iipateni ezikhangeleka zigqibelele kwiCAD kodwa zivelise izindlu zesilinda ezijijekileyo emva kokupholisa. Iqela lethu liqinisekisa uyilo ngalunye lwepateni ngokuchasene nedatha yokulinganisa i-thermal-kwaye ihlengahlengisa isango, ukunyuka, kunye nobukhulu beqokobhe phambi kokugalelwa kokuqala.
Apho ukuhlanganiswa ngokuthe nkqo kuphelisa iindawo ezifihlakeleyo zokungaphumeleli
Uninzi lwabaseki banikezela ngeevenkile kwiivenkile zoomatshini bomntu wesithathu. Oko kudala imigangatho emithathu yomngcipheko: ukukhukuliseka okuphakathi phakathi kokusalwa kunye nomatshini, ukulahleka kokulandeleka kwezinto, kunye nokulibaziseka kwengxelo malunga neziphene zepateni. Siqhuba zombini utyalo-mali kunye ne-5-axis CNC machining phantsi kophahla oluqinisekisiweyo lwe-ISO 9001 eQingdao. Xa indlu yempompo yepiston ifika isuka eziko, ihamba ngokuthe ngqo kwi-Zeiss Contura G2 CMM yethu-hayi kwidokhi yezothutho. Silinganisa imilinganiselo ye-cast-cast, ithelekise kwiimodeli eziqikelelweyo zokunciphisa, kwaye silungise ipateni elandelayo ye-wax kwiiyure ezingama-48.
- AMS 5387 cobalt alloy alloy amalungu angena kwisisombululo se-annealing *phambi* kwe-machining-kungekhona emva-ukuzinzisa i-microstructure kunye nokuthintela ukugqwetheka ngexesha lokusila.
- Yonke intsimbi yokuphosa ifumana uhlalutyo olupheleleyo lwe-spectral kunye novavanyo lwe-tensile; iingxelo ziquka amandla okwenene esivuno vs. ASTM A958 spec
- Ukugqitywa komphezulu kulawulwa ekupheleni-ukuya-ekupheleni: ukwakheka kweqokobhe leceramic kuchaphazela amaxabiso e-Ra, amisela ukuba sifaka ukuchama kwe-shot okanye i-electropolish post-machining.
Oku akukho lula-lulawulo oluqhutywa yi-physics. I-winch center shaft roller eyenziwe nge-ductile iron kufuneka igcine ukuqina kwe-285 HB kuwo wonke umjikelezo wayo. Ukuba ukuphosa kuphola ngokungafaniyo, umatshini utyhila iindawo ezithambileyo. Ukubeka iliso kwethu kwisithando somlilo sifaka iqondo lobushushu rhoqo kwimizuzwana engama-90 ngexesha le-shakeout. Sinxibelelanisa ezo log kunye neemephu zobunzima ukusuka kwindawo nganye egqityiweyo. Loo datha ibuyela kwipatheni ye-wax yokubekwa ngaphakathi kokungunda.
Ukuqinisekiswa kwehlabathi lokwenyani-hayi nje ukuthobela
Abanye ababoneleli badwelisa "i-ISO certified" kunye "ne-CNC ekwaziyo" kodwa abanalo ulwazi oluqinisekisiweyo lwesicelo. Asifikeleli nje kwimigangatho-siyavavanya ngokuchasene neendlela zokungaphumeleli. Iiplagi zethu ze-cobalt alloy zenze imijikelo ye-14,000 kwindawo efanisiweyo yeoli kunye negesi ephantsi komhlaba ngaphambi kokukhululwa. Iivalvu zoxinzelelo zavavanywa nge-hydrostatically kwi-1.5 × uxinzelelo olulinganisiwe, emva koko lwahlolwa ngedayi yokungena kunye novavanyo lwe-ultrasonic lwe-subsurface discontinuities. Ezi ayizongezo ezikhethiweyo. Zakhelwe kwinkonzo yethu yokuphosa iwax kuba abathengi bathumela ezi nxalenye kwiinkqubo ezibaluleke kakhulu zokhuseleko.
Sikwahlaba umkhosi into *engenakuphoswa* ngokuthembekileyo-kwangethuba. Umthengi wakha wathumela umzobo wodonga olucekethekileyo (2.3 mm) lwentsimbi engenasici kunye neepaseji zangaphakathi ezinqamlezileyo. Iinjineli zethu ziye zaqhuba ukulinganisa okuhamba-hambayo kwipatheni ye-wax kwaye zachonga ukuhamba kwesinyithi esisiphithiphithi esinokubangela ukuvalwa okubandayo. Endaweni yokucaphula ngokungaboniyo, sicebise indlela ye-hybrid: utyalo-mali-luphose umzimba ophambili, emva koko umatshini we-CNC iimpawu zangaphakathi. Oko kusindise i-37% kwiindleko zizonke xa kuthelekiswa nokuzama ukunyanzela ijometri ngokuphosa kuphela.
Ukukhetha iqabane lakho lenkonzo yokuphosa iwax
Buza imibuzo emithathu ngaphambi kokuba wenze:
- Ngaba banokukubonisa iingxelo zeCMM zenani lamva nje lebakala lakho elichanekileyo-hayi iisampulu eziqhelekileyo?
- Ngaba benza isiqinisekiso sempahla engenayo *kwaye* bagcine iikhuphoni ezibonakalayo kubo bonke ubushushu ukuze baphinde bavavanywe?
- Xa umyinge uwela ngaphandle kokunyamezelana, ngaba babuyisela inxalenye enesiphene kunye neefoto ezichazwe kunye nohlalutyo lwengcambu-okanye bakhuphe enye indawo?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iimpendulo ewe kuzo zontathu. Sibhala onke amanqanaba ohlolo, sigcina zonke iirekhodi zolungelelwaniso, kwaye sabelane ngeedosi ezipheleleyo zokulandeleka kunye nabathengi. Inkonzo yethu yokuphosa i-wax isekela i-prototype iqhuba njengento encinci njengamaqhekeza e-5 kunye nomthamo wemveliso ukuya kwiiyunithi ze-5,000 ngonyaka-ngaphandle kokutshintsha izixhobo okanye iiparitha zenkqubo. Ngenxa yokuba ukuhambelana akusiyo into ekujoliswe kuyo. Yisiseko.
Ukuba iprojekthi yakho elandelayo ifuna imfezeko yomgangatho phantsi koxinzelelo oluphezulu, ukumelana nokubola kumajelo osasazo andlongondlongo, okanye ubomi bokudinwa obugqithisa kwimijikelo eyi-10⁷—qala ngenkonzo yokuphosa iwax ephatha isinyithi njengenjineli, hayi ubugcisa. Ukuchaneka kuqala apho i-wax inyibilika.
