Iyo injeniyeri zikeneye ubushobozi bwo gukora inganda ziciriritse ziciriritse kubice biri munsi ya 5 mm hamwe no kwihanganira mm 0.01, ntibikunze gutangirana nishakisha rya Google. Batangirana na prototype yananiwe - cobalt alloy nozzle yamenetse mugihe cyo gupima ingufu za hydraulic, inzu ya pompe yamenetse yizengurutse nyuma yo kuvura ubushyuhe, cyangwa icyuma cya shitingi cya shitingi cyambaye kimwe nyuma yamasaha 200 mumiterere yumunyu wuzuye umunyu. Twabonye byose uko ari bitatu - kandi twakosoye buri kimwe atari uguhindura kwihanganira, ahubwo twongeye gutekereza uburyo inganda ziciriritse ziciriritse zikuraho itandukaniro riri hagati yifu ya metallurgie no kwizerwa kumikorere.
Gushushanya ibyuma bya Micro ntabwo ari "MIM ntoya" gusa - bisaba kugenzura ibyuma bya micron
Uburyo bwo gutera inshinge ntoya (μMIM) itandukanye na MIM isanzwe muburyo butatu butavugwaho rumwe: ingano yubunini bwa powder igomba kuguma munsi ya 5 μm D90, kuvanaho binder bisaba buhoro buhoro umwirondoro kugirango wirinde gucika mikoro mu rukuta ruto (<0.3 mm), hamwe no gucumura bigomba kugera kuri ≥98.5% yubucucike bwamahame nta guhunika ingano. Abatanga ibicuruzwa benshi bandika ibice nka "micro" niba biri munsi ya 10 g - ariko ibice bya μMIM nyabyo bipima 0,02-2,5 g hamwe nibiranga nka 0.15 mm ya diametre yo gukonjesha, uburebure bwa mm 0.08, hamwe na GD&T guhamagarira umwanya wukuri muri mm 0.005.
Niyo mpamvu guhitamo ibikoresho bidahitamo - nicyemezo cya mbere cyubwubatsi. AMS 5387 cobalt alloy ikora aho 316 idashobora kwangirika: mugihe cyihuta cyihuta cyibidukikije, kuri 450 ° C ikora, munsi yumutwaro wumunaniro ukabije urenga 10⁷. Ariko imiterere yacyo nziza ituma itababarira mugihe cyo kwishyura. Dukoresha ibyiciro bibiri bya solvent / ubushyuhe hamwe nigihe-cyo kugenzura-gutakaza-gutakaza igihe - ntabwo ari igihe cyagenwe - kubera ko icyiciro-cy-icyiciro cyo gutandukana mugipimo cyo gukwirakwiza binder kigira ingaruka ku busugire bwicyatsi kibisi.
Kwishyira hamwe bihagaritse gukemura icyo outsourcing icamo
Kunanirwa kwa μMIM kwinshi gusubira inyuma kubiganza: amato ya MIM atanga ibicuruzwa byacumuye; iduka ryimashini riharanira gukora kumurimo wa mm-3 ya diametre; ubushyuhe butanga ubushyuhe ntibushobora kwigana igitereko nyacyo gikenewe kugirango AMS 5387 ikwirakwize karbide. Dukoresha intambwe zose uko ari eshatu munsi yinzu imwe yemewe ya ISO 9001 muri Qingdao - kandi ibyo byose bihindura.
- Imashini ya CNC ikoresha insyo 5-axis hamwe nibikoresho bizima hamwe no gukora iperereza - birakomeye mugihe uhuye na 0.2 mm yuburebure bwa mm 0.003 mm
- Kuvura ubushyuhe birimo vacuum carburizing kubice bishingiye kuri T800, hamwe na ogisijeni igice cyigenzura <10⁻⁴ mbar kugirango wirinde okiside yubuso hejuru
- Kurangiza ubuso bukoresha amashanyarazi hamwe nubucucike bwashizwe kuri geometrie yaho - nta mfuruka ihumye, nta mikoro iciriritse mu nzira zitemba
Ntabwo dufite kwihanganira gusa. Dufite * kwihanganira imikorere: kwihanganira ubuso bwa Ra ≤ 0.2 mm kuri kashe yo gufunga, gukomera kwa micro-gukomera kuri 0.5 mm kwambukiranya ibice, hamwe numwirondoro wibisigisigi byagenzuwe hakoreshejwe itandukaniro rya XRD - ntabwo bigoye gusa kugenzura Rockwell C.
Igishushanyo-cyo-gukora gitangira mbere yuko dosiye yambere ya CAD ibikwa
Abakiriya bakunze kubaza bati: “Urashobora gukora ibi?” Turasubiza: “Yego - ariko gusa iyo duhinduye radiyo hano, twimura aho irembo rihari, kandi tugaragaza ikirere gitandukanye.” Kurugero, icyuma cyitwa cobalt gishyizwe hamwe na 0.4 mm yimbere yimbere byananiranye inshuro nyinshi kugeza igihe twavuye mumurongo wimbere nyuma ya sinter tugahindura urudodo mugihe cyo gutunganya icyatsi kibisi-hanyuma tugashyiraho nitride yubushyuhe buke aho gukomera bisanzwe. Izo mpinduka zagabanije igipimo cyavuye kuri 37% kigera kuri 1.8%.
Twemeza ibishushanyo byose kugirango μMIM ishoboke - kugenzura inguni (byibuze 0.5 °), twirinda impande zimbere (R ≥ 0.1 mm), kugenzura inzibacyuho y’urukuta (no> 3: 1), hamwe no kwerekana imigozi ihuza ibipimo byerekana imirongo isudira mumazu ya pompe yoroheje. Niba GD&T yawe ihamagaye umwanya uhuriweho kuri datum eshatu ziri hagati ya mm 2 zitandukanye, tuzabishyiraho ibendera - kandi dusabe ingamba imwe ya datum ingamba zitanga ibisubizo bimwe bikora hamwe nigiciro cyo kugenzura 40%.
Kwizerwa ntabwo bipimwa mubyemezo - byubatswe muri buri kintu
Gukurikirana ntabwo ari impapuro. Ni kode ya lazeri yuzuye kuri buri gice, ibikoresho fatizo bifitanye isano no gucumura kugiti cye, na raporo ya CMM yabitswe mumyaka 15 - ntabwo ari ubugenzuzi gusa, ariko rero mugihe raporo yumukiriya yambaye kumasaha 12.000 yo gukora, turashobora gukuramo igiti nyacyo cyo kuvura ubushyuhe, inyandiko za binder, hamwe na optique interferometrie scan kuva umunsi wambere wibyakozwe.
Uruganda rwacu ruciriritse rukora ibyuma bitanga hydraulic OEMs mubudage bisaba EN 10204 3.1 cert, abashoramari ba peteroli muri Texas basaba kubahiriza API Q1, hamwe nabashushanya pompe muri Singapuru bakeneye kwemeza ASME BPE kurangiza. Ikibahuza ntabwo ari geografiya - ni ukwanga kwakira "byiza bihagije" kubice bifunga kashe, metero, cyangwa bizunguruka munsi yuburemere bukomeye bwubuzima.
Niba umushinga wawe ukurikira muto urimo cobalt alloys, kwihanganira kwihanganira urukuta ruto, cyangwa hejuru yimikorere igomba kurokoka itangazamakuru ryangiza - tangira ukoresheje imyitwarire yibintu, ntabwo ari imashini. Tangira hamwe na nyirubwite, ntabwo wavuze umuvuduko. Tangira numufatanyabikorwa ufata buri 0,02 mm gutandukana nkiperereza ryimpamvu, ntabwo ari ukwihanganirana. Nuburyo buryo busobanutse neza.
