Iyo amatsinda yamasoko ashakisha a icyuma cyo gutera inshinge, ntibakunze kwifuza ibitekerezo-bashaka imibare, gucuruza, hamwe nukuri kwisi bashobora gukurura * uyumunsi *. Twasubiyemo imishinga irenga 217 MIM kuva muri 2020. Muri buri kibazo, ikibazo cya mbere nticyari "Urashobora kubikora?" - cyari "Kuki iki gice kigura amadorari 48.60 aho kuba $ 29?"
Abashoferi Bane B'ibiciro Ntushobora Kwirengagiza (Ariko Abaguzi Benshi birengagiza)
MIM ntabwo igiciro nka CNC cyangwa gupfa casting. Imiterere yikiguzi yihishe muburyo bugaragara - no kuyisoma nabi isesagura ingengo yigihe. Dore icyimura inshinge:
- Igice kitoroshye hamwe nigikoresho cyo gukuramo amortisation: Igice gifite ibice 3, uburebure bwa mm 0,05 mm, hamwe na ± 0,02 mm kwihanganira GD&T bisaba ibyuma bikomye hamwe na electrode ya micro-EDM. Icyo gikoresho cyo gukoresha? $ 28,000– $ 42,000. Ariko niba ingano yumwaka ari 50.000, ayo ni $ 0.56– $ 0.84 kuri buri gice. Kureka kubice 5000? Ubu ni $ 5.60– $ 8.40. Umubumbe ntabwo "ari byiza kugira" -ni umurinzi wubukungu bwa MIM.
- Guhitamo ibikoresho ntabwo bijyanye na alloy grade wenyine: 17-4PH ibyuma bitagira umuyonga bigura ~ $ 24 / kg mbisi. Ariko AMS 5387 cobalt? $ 142 / kg - kandi ubucucike bwayo buri hejuru ya 12%. Misa nyinshi isobanura ibiryo byinshi, igihe cyo gutesha agaciro, imbaraga nyinshi zo gucumura. Ikibi kurushaho: ibinyobwa bya cobalt bisaba gucumura vacuum hamwe no kugenzura neza ogisijeni. Itanura rimwe ritateganijwe gutandukana ryongeraho $ 1.800 mugice gisakaye. Turabikurikirana mugihe nyacyo - ntabwo biri kurupapuro.
- Ibikorwa bya kabiri niho bije itemba bucece: "Hafi-net-shusho" yumvikana neza kugeza ubonye uburinganire bwubuso: Ra 3.2–4.8 µm. Niba inzu yawe ya pompe isaba Ra 0.8 µm kugirango uburinganire bwa kashe, uzakenera CNC kurangiza-gutunganya kumaso 3-5 akomeye. Ibyo byongera $ 6.30– $ 11.20 kuri buri gice - kandi byica umwanya wambere. Turabashyira ibendera hakiri kare mugihe cyo gusuzuma DFM, ntabwo nyuma yo gukata ibikoresho.
- Ihagarikwa ryimiterere ntabwo ryemewe-ryakozwe: Sintering shrinkage igereranya 15-18%, ariko ntabwo yigeze iba imwe. Urukuta ruto rugabanuka kuruta ibice byinshi. Inguni zimbere zigabanuka zitandukanye nizindi zo hanze. Hatariho ibikoresho byishyurwa byubushakashatsi hamwe no mubikorwa bya CMM kwemeza ibyatsi, icyatsi, nicyaha, uzabona 30% kwangwa-ingingo ya mbere. Dukoresha amakarita yo gushushanya kuri buri geometrie nshya - dukoresheje ibyiciro byukuri, ntabwo twigana.
Kuki "Uruganda Ruciriritse" Akenshi Bisobanura "Inteko ishobora guhura n'ingaruka"
Abaguzi bamwe birukana igiciro gito cya MIM cyavuzwe - hanyuma bakavumbura “uruganda” rutanga inguzanyo kubandi bantu batunganya imiti, bakinjira kumurongo w'itanura basangiye, no kugenzura muri laboratoire itemewe. Gukurikirana birashira. Batch-to-batch gukomera guhinduka hit 15 HRB. Umukiriya umwe wa hydraulic valve yakiriye ibice 12.000 bifite imiterere idahuye-bitera umunaniro utaragera kuri 42% byumuvuduko ukabije.
Ntabwo dushyira hanze intambwe yibanze. Ikigo cyacu cyujuje ISO muri Qingdao gikemura ibintu byose: kuvanga amatungo, gutera inshinge, gukuramo ibishishwa, gusohora amashyuza, gucumura vacuum, HIP (niba bikenewe), hamwe na metero zuzuye. Igice cyose cya cobalt-nikel gitwara ibintu byose byuzuye - kuva kumpapuro zurusyo kugeza gucumura kugeza raporo ya CMM yanyuma. Iyo disipuline yongeraho ~ 7% kubiciro fatizo-ariko ikuraho $ 220,000 + mukibazo cyo gutsindwa kumurima kubice byingenzi.
Nigute wagabanya ikiguzi nyacyo-utarinze kwigomwa imikorere
Dufasha abaguzi bashishikajwe ningengo yimari kugabanya igiciro cyubutaka-ntabwo ari igiciro cyibice gusa. Ibi bikorwa bitatu bitanga ROI ipimwa:
- Ongera uhindure ibicumuro bya fiziki, ntabwo byoroshye CAD gusa: Simbuza imfuruka zimbere imbere na .3 0.3 mm radii. Ongera uburebure bwurukuta kuva kuri mm 1,2 kugeza kuri 1.8 mm. Kuraho umwobo uhumye kurenza 4 × diameter. Izi mpinduka akenshi zigabanya igiciro cyibikoresho 22% kandi bitezimbere umusaruro wambere-kuva kuri 68% ukagera kuri 94%.
- Funga ibikoresho byerekana ibikenewe-ntabwo bishushanya umurage. Twemeza imikorere dukoresheje ASTM E8 igeragezwa ryikigereranyo kuri coupons yacumuye - ntabwo ari ibitekerezo.
- Huza inzira ya kabiri mumasezerano imwe: Aho kugirango dusubiremo MIM + gutunganya + passivation ukwayo, twagabanije gutanga ibicuruzwa. Kubijyanye nigitutu cyingutu gisaba CNC gusya, guhuza ibyambu, hamwe na electropolishing, ibiciro byahujwe bigabanya ubuyobozi hejuru ya 31% kandi bigabanya amakosa ya handoff kuri 74%.
Ijambo ryanyuma: Igiciro ni Sisitemu - Ntabwo ari Umubare
A icyuma cyo gutera inshinge cote irakubwira bike kugeza igihe umenye uko yubatswe. Igikoresho cyo gukuramo. Ubucucike bwibintu nimyitwarire yicyaha. Icyiciro cya kabiri gishingiye. Ubujyakuzimu. Izi ntabwo ari ibisobanuro-ibisobanuro.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka ibice bya MIM kuri sisitemu ya hydraulic, pompe ya peteroli na gazi, hamwe na shitingi yimodoka ya winch-aho gutsindwa atari amahitamo. Ntabwo dushishikajwe numubare muto wo mumutwe. Dutezimbere igiciro gito cyo gutunga nyirubwite mugushushanya, kubyara, hamwe nubuzima bwumurima.
Niba umushinga wawe utaha wa MIM usaba ubunyangamugayo buringaniye munsi ya 350 bar, ambara kwihanganira ibintu byoroshye, cyangwa kurwanya ruswa mubidukikije bya H₂S - tangira ukoresheje ikarita yo kugabanuka, ntabwo ari urupapuro. Umufatanyabikorwa mwiza ntabwo avuga ibiciro gusa. Bashyira ahagaragara physics inyuma yacyo.
