Xa iinjineli zidinga isakhono sefektri yokubumba inaliti yentsimbi encinci kumacandelo angaphantsi kwe-5 mm ngonyamezelo ± 0.01 mm, abafane baqale ngophendlo lukaGoogle. Baqala ngeprototype engaphumeleliyo - i-cobalt alloy nozzle eyaqhekeka ngexesha lovavanyo loxinzelelo lwe-hydraulic, umbhobho wezindlu wempompo oye wakhukuliseka ngaphandle komjikelo emva kokunyangwa kobushushu, okanye i-winch centre shaft roller eyayinxiba ngokungafaniyo emva kweeyure ezingama-200 kwiimeko ezigcwele ityuwa elunxwemeni. Sizibonile zonke zontathu-kwaye sizilungisile nganye ingeyiyo ngokuhlengahlengisa ukunyamezelana, kodwa ngokuphinda sicinge ukuba ukuchaneka kwenxalenye encinci yokuvelisa ibhulorho phakathi komgubo wesinyithi kunye nokuthembeka kokusebenza.
Ukubumba inaliti yentsimbi encinci ayisiyo "MIM encinci" nje - ifuna ulawulo lwetsimbi kwisikali semicron
Ukubunjwa kwenaliti yentsimbi eyinyani (μMIM) yohluka kwiMIM eqhelekileyo ngeendlela ezintathu ezingaxoxisaniyo: Ukuhanjiswa kobungakanani besuntswana elingumgubo kufuneka kuhlale ngaphantsi kwe-5 μm D.90, ukususwa kwe-binder kufuna iprofayili ye-gradient ye-thermal ukuthintela ukukrazula kancinci kwiindonga ezibhityileyo (<0.3 mm), kunye ne-sintering kufuneka ifezekise i-≥98.5% yoxinaniso lwethiyori ngaphandle kwe-grain coarsening. Ababoneleli abaninzi babhala iinxalenye njenge "micro" ukuba zingaphantsi kwe-10 g - kodwa iinxalenye zokwenyani ze-μMIM zinobunzima obuyi-0.05-2.5 g kwaye zineempawu ezifana netshaneli zokupholisa eziyi-0.15 mm-diameter, ubukhulu bodonga obuyi-0.08 mm, kunye ne-GD&T callouts yendawo yokwenyani ngaphakathi kwe-0.005 mm.
Yiyo loo nto ukukhetha izinto eziphathekayo kungenakuzikhethela - sisigqibo sokuqala sobunjineli. I-AMS 5387 i-cobalt alloy isebenza apho i-316 i-stainless ihluleka: kwiindawo eziphakamileyo ze-slurry, kwi-450 ° C yokusebenza kwexesha, phantsi kwemithwalo yokudinwa kwe-cyclic edlula imijikelezo ye-10⁷. Kodwa ukwakheka kwayo okucolekileyo kwenza ukuba ingaxoleli ngexesha lokuboleka. Sisebenzisa inkqubo ye-solvent/i-thermal enezigaba ezibini kunye nexesha langempela lokujonga ilahleko yobunzima - hayi imijikelo yexesha elimiselweyo - kuba ukuhluka kwe-batch-to-batch kumazinga okusasazwa kwe-binder kuchaphazela ngokuthe ngqo inxalenye eluhlaza.
Udibaniso oluthe nkqo lusombulula ukuba yintoni ikhefu lokuthengisa ngaphandle
Uninzi lweentsilelo ze-μMIM zibuyela emva kwi-handoffs: umboneleli we-MIM uthumela izikhewu ezingenanto; ivenkile yomatshini iyasokola ngokusebenza kwi-3-mm-diameter flanges; umntu ophatha ubushushu akakwazi ukuphinda-phinda eyona rampu i-austenitizing efunekayo kwi-AMS 5387's carbide dispersion. Siqhuba onke amanyathelo amathathu phantsi kophahla oluqinisekisiweyo lwe-ISO 9001 eQingdao - kwaye loo nto itshintsha yonke into.
- I-CNC machining isebenzisa i-5-axis mills enezixhobo eziphilayo kunye nenkqubo yokuhlola - ibaluleke kakhulu xa ijongene ne-0.2 mm-flange ene-± 0.003 mm flatness
- Unyango lobushushu lubandakanya i-vacuum carburizing ye-T800-based components, kunye noxinzelelo lweoksijini olungaphelelanga olulawulwayo. <10⁻⁴ mbar ukunqanda i-oxidation yomhlaba kwiikhonto ezintsonkothileyo
- Ukugqityezelwa komphezulu kusebenzisa ukuxinana kwe-electropolishing kunye noxinaniso lwangoku olufakwe kwimephu yejometri yendawo - akukho zikona zingaboniyo, akukho migobho mincinci kwiindlela zokuhamba
Asibambi nje ukunyamezelana. Sibambe *ukunyamezela* okusebenzayo: uburhabaxa bomphezulu Ra ≤ 0.2 μm ebusweni bokutywina, ubulukhuni be-micro-hardness ngaphaya kwe-0.5 mm ye-cross-sections, kunye neeprofayili ezishiyekileyo zoxinzelelo eziqinisekisiwe nge-XRD diffraction - kungekhona nje ukuqina kweetshekhi ze-Rockwell C.
Uyilo-lwe-mveliso luqala phambi kokuba ifayile yokuqala ye-CAD igcinwe
Abathengi bahlala bebuza: "Ngaba ungayenza le nto?" Siyaphendula: "Ewe - kodwa kuphela ukuba sihlengahlengisa iradiyasi apha, sihambisa indawo yesango apho, kwaye sichaze umoya owahlukileyo wokulila." Ngokomzekelo, iplagi ye-cobalt alloy ene-0.4 mm yangaphakathi intambo yangaphakathi ayiphumelelanga ngokuphindaphindiweyo de sisuke sisuka kwi-post-sinter yangaphakathi ukuya kwi-thread-forming ngexesha lokwenziwa kwe-green-state machining - emva koko sisebenzise i-nitriding yobushushu obuphantsi endaweni yokuqina okuqhelekileyo. Olo tshintsho lwehlise izinga lokulahlwa ukusuka kwi-37% ukuya kwi-1.8%.
Siqinisekisa yonke umzobo μMIM ukwenzeka — ukujonga ii-engile idrafti (ubuncinane 0.5 °), ukuphepha iikona ezibukhali zangaphakathi (R ≥ 0.1 mm), uguqulo longqinisiso eludongeni (akukho > 3: 1 ratio), kunye nokuhamba kwe-binder modeling ukuqikelela imigca ye-weld kwizindlu zempompo ezinqabileyo. Ukuba i-GD&T yakho ibiza indawo ehlanganisiweyo kwiidatha ezintathu eziqelelene nge-2 mm, siya kuyiflegi - kwaye sicebise isicwangciso sedatha esinomphezulu omnye esibonelela ngesiphumo esisebenzayo esifanayo kunye ne-40% yeendleko zokuhlola ezisezantsi.
Ukuthembeka akulinganiswa kwizatifikethi - yakhelwe kuyo yonke indawo
Ukulandeleka akungomsebenzi wamaphepha. Iikhowudi ze-laser-etched lot kwinxalenye nganye, iicerts zemathiriyeli ekrwada ezibotshelelwe kwi-sintering run, kunye neengxelo zeCMM zigcinwe iminyaka eli-15 - hayi nje uphicotho-zincwadi, kodwa ke xa iingxelo zomthengi zinxiba kwiiyure zokusebenza ezili-12,000, sinokutsala eyona log yokuphatha ubushushu, irekhodi ye-binder, kunye ne-optical interfer.ometry scan ukusuka kwimveliso yosuku olunye.
Umzi-mveliso wethu wokubumba inaliti yentsimbi encinci usebenzisa ii-OEMs zehydraulic eJamani ezifuna iicerts ze-EN 10204 3.1, iikontraka ze-oyile e-Texas zifuna ukuthotyelwa kwe-API Q1, kunye nabayili bempompo eSingapore abafuna ukuqinisekiswa komphezulu we-ASME BPE. Into ebadibanisayo ayiyojografi - kukwala ukwamkela "ukulunga ngokwaneleyo" kwiindawo ezitywinayo, imitha, okanye ezijikelezayo phantsi kwemithwalo ebalulekileyo ebomini.
Ukuba iprojekthi yakho yecandelo elincinci elilandelayo libandakanya i-cobalt alloys, ukunyamezela okuqinileyo iindonga ezinqabileyo, okanye indawo esebenzayo ekufuneka iphile kwimithombo yeendaba eyingozi - qala ngokuziphatha kwezinto, hayi i-specs yomatshini. Qala ngobunini benkqubo, hayi isantya sokucaphula. Qala kunye neqabane eliphatha yonke i-0.02 mm ukutenxa njengophando lwengcambu, kungekhona ukunyamezela ukunyamezela. Yiloo ndlela ukuchaneka kuqikelelwa ngayo.
