Xa abantu abaninzi besiva 'ukuveliswa komgubo wesinyithi', ngoko nangoko baye bafane nomfanekiso wokucofa kunye ne-sinter operation elula—ukudibanisa umgubo, uwucinezele ube kwimilo, kwaye uwubhake. Leyo yikhosi ye-101, kodwa inyani kumgangatho wevenkile, ngakumbi xa udibanisa la malungu kwiindibano ezinkulu okanye izicelo ezifunayo, lirhamncwa elahlukileyo. Ayikokwenza nje imilo; imalunga nokulawula ingxinano yegradients, ukuqonda indlela i-alloying elements eziphatha ngayo kwifomu yomgubo ngokuchasene nokunyibilika, kunye nokujongana neenyani zasemva kwe-sintering zolawulo lwe-dimensional. Abathengi abaninzi beza kuthi Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ukucinga PM yi drop-in ngexabiso eliphantsi endaweni yomatshini okanye baphoswe inxalenye, kwaye kulapho iseti yokuqala yeentloko ezibuhlungu iqala.
Ingqondo yezinto eziphathekayo: Ayisiyiyo nje isinyithi esinomgubo
Olunye utshintsho olukhulu ekucingeni zizinto eziphathekayo ngokwazo. Ukusebenza kunye intsimbi engenasici okanye ialloys esekwe nickel kwi-investment yethu yotyalo-mali kunye nemigca yomatshini ye-CNC ikunika intuition ethile malunga nokuhamba, ukuncipha, kunye nokunxiba izixhobo. Ngomgubo, loo intuition iyajikajika. Ukusabalalisa ubungakanani be-particle, imilo (i-spherical vs. irregular), kunye ne-lubricant exutywe kuyo-bonke bayalela ukuhamba kwi-die kunye namandla okugqibela aluhlaza. Siye safumana umgubo obonakala ugqibelele kwiphepha elithile kodwa wala ukuqukuqela rhoqo, nto leyo ebangela ukugcwalisa imiba kwizixhobo ezinzima. Ufunda ukucela idatha yovavanyo lomgangatho wokuhamba, hayi nje isatifikethi.
Emva koko kukho i-alloying. Ekunyibilikeni, ufumana umxube olinganayo. Kwi ukuveliswa kwesinyithi somgubo, uhlala usebenza ngomgubo osele ufakwe ngaphambili okanye udiffusion-bond. Iprofayili ye-sintering ukufezekisa i-homogenization efanelekileyo ngaphandle kokuphazamisa inxalenye yi-tightrope walk. Kwicandelo elinxibileyo eliphakamileyo esiliprototype sisebenzisa i-cobalt-based alloy powder, umjikelezo oqhelekileyo we-sintering ukhokelela ekukhuleni okuziinkozo okugqithisileyo kwamanye amacandelo, ukubulala ukuxhathisa ukunxiba. Kwafuneka sibuyele umva kwaye sisebenze kunye nomthengisi we-powder ukuze sidibanise iphrofayili yexesha lobushushu, songeza isigaba sokupholisa ngokukhawuleza emva kwe-sinter. Ngala madabi ezandla phezu kwezinto ezithi iincwadi zezifundo zikhanye.
Nongcoliso—umbulali ongathethiyo. Isixa esincinci sezinto zangaphandle okanye i-oxidation ngexesha lokuphatha linokudala iindawo ezibuthathaka. Amava ethu kwiinkqubo ezicocekileyo ezikufutshane negumbi lotyalo-mali asenze sanexhala malunga noku kwangethuba. Siphumeze izikhululo zokuphatha umgubo ezizinikeleyo, ezibonakala ngathi zigqithise de salanda ibhetshi yamacandelo anobulukhuni obungahambelaniyo sibuyela kwisingxobo sokuxuba esingcolisekileyo. I ukuveliswa komgubo wesinyithi kuninzi malunga nokuhanjiswa kunye nokugcinwa kwendlu njengoko kunjalo malunga noshicilelo.
I-Tooling Tango: Apho ithiyori idibana khona
I-Tooling kulapho iindleko kunye nobunzima bufihla khona. Wonke umntu ugxininise kwi-tonnage ye-press, kodwa i-design ye-die, i-punch tolerances, kunye nokukhethwa kwezinto eziphathekayo kwezixhobo ngokwazo zizinto ezenza okanye ziphule ukuveliswa kwemveliso. Siyila kwaye senze izixhobo zangaphakathi zokusasa kunye nemigca yomatshini, ke sasebenzisa loo ngqondo kwi-PM. Impazamo enkulu ekuqaleni.
