Iyo injeniyeri n'abashinzwe gutanga amasoko bashakisha uruganda rutanga ibyuma, ntibakenera gake urutonde rwubushobozi rusange cyangwa udutabo twinshi. Bakeneye gihamya-gihamya yerekana ko umufatanyabikorwa ashobora kwihanganira mm 0,01 mm ku ntebe ya cobalt-nikel, gutanga amazu ya pompe ya AMS 5387 hamwe na microstructure yuzuye, kandi agakemura amakimbirane ya GD&T mbere yo guca igikoresho cya mbere. Ubwo ntabwo ari ubushobozi bwa theoretical. Iyo ni disipuline ikora.
Kuki "Metal Injection Molding" Wenyine Nijambo Rishakisha Ryayobya
Abaguzi benshi bandika "uruganda rutanga ibyuma byerekana ibicuruzwa" muri Google - hanyuma bakagwa kubacuruzi batanga ibicuruzwa, basiba ibyemezo, cyangwa kubura metero zo munzu. Ariko dore ibyo kohereza-nyabyo kwisi bitwigisha: MIM ni iyo kwizerwa gusa nko kugenzura ibishishwa, kuvura neza ubushyuhe, no kwemeza ibipimo inyuma. Igice gikozwe muri T800 cobalt gishingiye ku mavuta cyananiranye ntigisohoka - ariko iyo gusiganwa ku magare byerekana ubushyuhe bwa karbide ikwirakwizwa. Twabonye ibyiciro bitatu byananiranye kubitanga umwe kuko chet yibikoresho byemewe byemewe hatabanje kugenzurwa umusaruro wa AMS 5387 ukwirakwira hose. Kwizerwa kwukuri gutangira mbere yuko ibiryo byinjira muri hopper.
Ubushobozi Bune butaganira ugomba kugenzura
Ntubaze “Ukora MIM?” Baza aho:
- Urashobora kwemeza chimie ya alloy kuri ASTM E353 * mbere yo * gutesha agaciro? Ntabwo ari urusyo gusa - raporo nyayo ya OES cyangwa ICP-MS ihujwe numero yawe.
- Uhuza HIP (Hot Isostatic Pressing) hamwe no kuvura ubushyuhe bwa nyuma ya sinter mukuzunguruka kwikirere kimwe? Kureka iyi ntambwe bisiga ibintu bisigaye mubice bya pompe yumuvuduko mwinshi-nubwo CMM ivuga ko ibipimo biri "muburyo bwihariye."
- Igice cyose cyapimwe na Calibrated CMM * na * optique igereranya na guhamagarwa kwa GD&T - ntabwo ari umurongo gusa? Twigeze kubona 0,04 mm ikosa ryumwanya kuri nozzle igenda irengana cheque ya Caliper ariko itera kashe kumeneka munsi ya 350.
- Urashobora gutanga ibisobanuro byuzuye: ubushyuhe bwinshi → sinter curve → Ibipimo bya HIP map ikarita yanyuma? Ntabwo ari kashe ya PDF gusa. Amadosiye yamakuru yuzuye, yashyizweho igihe, abitswe imyaka 10+.
Aba ntabwo ari "beza-bafite." Nibigenzurwa byo gukumira.
Aho Gutera-Gukora Kwishyira hamwe Byahindutse Ubwiza Bwiza
Dore ibyo amaduka menshi ya MIM gusa atazakubwira: imibiri ya hydraulic valve umubiri usaba akenshi gukora inganda. Geometri yo hanze? Gukoresha MIM. Ubutaka bukomeye bwo gufunga no kumpande zicyambu? CNC yarangije nyuma yo gucumura kugirango yemeze Ra ≤ 0.4 µm na zeru burr. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora muri ubu buryo - ntabwo ari nko kwamamaza, ahubwo ni imyitozo ya buri munsi. Ikigo cyabo cyujuje ISO gikora ishoramari, guta umucanga, gutunganya imirongo myinshi, hamwe na MIM ikomoka hafi ya net-shusho itunganya igisenge kimwe. Kuki ibyo bifite akamaro? Kuberako kwaguka k'ubushyuhe bidahuye hagati ya sinteri na mashini zicika iyo ibikorwa byombi bisangiye kugenzura ibidukikije, gahunda imwe ya Calibibasi ya CMM, hamwe na metallurgiste imwe isuzuma micrografi.
Twabigerageje hamwe na piston pompe ya silindiri isaba silindrike ya mm 0,015 kuri bore ya mm 120. Abanywanyi bavuze ibisubizo bya MIM gusa hamwe no gusya kabiri - wongeyeho ibyumweru 3 bayobora igihe kandi bishobora kugoreka. Uburyo bwa QINGDAO bwakoresheje MIM kuri shell, hanyuma kurangiza-kurambirwa no kubaha bore muburyo bumwe bwo gufatisha kumisarani ya CNC itunganijwe neza. Igisubizo: 98% umusaruro-wambere wambere, nta rework, byuzuye ASME B16.34 ibyangombwa byubahirizwa birimo.
Reba Hanze y'amagambo - Kugenzura inzira Rigor
Igiciro cyo guhatanira ntacyo bivuze niba AMS 5387 ya cobalt alloy plug igeze hamwe na delta ferrite itamenyeshejwe hejuru ya 3%. Cyangwa niba ubuso burangiye butandukanye muburyo butandukanye kuko ibipimo byo kurangiza vibratory ntabwo byanditswe cyangwa byahinduwe kubice bya geometrie. Ubwizerwe nyabwo bugaragara munzira y'ubugenzuzi - ntabwo ari inyemezabuguzi.
QINGDAO QIANGSENYUAN yanditse protocole yubugenzuzi isaba: kugenzura ibintu byinjira (OES + gukomera), mugikorwa cyo kugenzura sinter yuzuye (uburyo bwa Archimedes), gusikana nyuma ya HIP ultrasonic scan kubusa kubutaka, hamwe no gupima imikorere yanyuma - nkibizamini byangirika byumuvuduko kuri 1.5 × igitutu cyakazi kumateraniro yose ya valve. Buri raporo itwara indangamuntu ya tekinike, inomero yumubare wibikoresho, na kalibrasi itariki yagenwe. Nta na kimwe kidasanzwe.
Ibi ntabwo ari bureaucracy. Nukuntu wirinda kunanirwa kumurima mubikoresho bya peteroli na gaze aho gusimbuza bisobanura $ 2M / kumunsi rigabanuka.
Intambwe ikurikiraho ntabwo ari iyindi RFQ-ni Isubiramo rya tekiniki
Mbere yo kohereza ibishushanyo, baza ibyabo ibicuruzwa bitanga ibitekerezo. Nukuri uruganda rutanga ibyuma ifata igishushanyo cyawe nkikibazo gihuriweho nubuhanga-ntabwo ari itegeko ryumusaruro utegereje gutunganywa.
Sura https: Nta kwinjira bisabwa. Nta kibanza cyo kugurisha. Gusa amakuru yimikorere-kuko ibice byuzuye ntabwo byubakiye kumasezerano. Zubatswe kubikorwa bisubirwamo, byagenzuwe, bigenzurwa nibikorwa.
