Iyo abajenjeri bagaragaje ibice bigoye, byuzuye-byuzuye bya sisitemu ya hydraulic cyangwa serivisi ya peteroli na gaze, ntibakunze gutangirana no "guta ifuro." Batangirana nikibazo: inzu ya valve itemba munsi yumubari 400, silinderi ya pompe ya piston hamwe na micro-crack nyuma yo gusiganwa ku magare, cyangwa imashini ya winch center shaft roller ikananirwa imburagihe mubihe bibi byo hanze. Nibwo guta ifuro yatakaye bidahinduka gusa - ahubwo igisubizo cyonyine gifatika. Kandi aho niho a uruganda rwo guta ifuro hamwe na disipuline yimbitse hamwe no kugenzura inzira ihuriweho ikora itandukaniro.
Gutakaza ifuro ryatakaye ntabwo ari "guta umucanga hamwe nifuro." Nibisobanuro bitomoye-byongeweho bivangavanze: ishusho ya EPS yakozwe na CNC yakozwe na CNC, irashyingurwa mumucanga wa silika itagira umupaka, hanyuma igahumeka * mukibanza * nicyuma gishongeshejwe. Nta murongo wo gutandukana. Nta cores to shift. Nta mfuruka igabanya geometrie. Ariko intsinzi ishingiye kubintu bitatu bidashobora kuganirwaho - uburyo butajegajega mugihe cyo gutwikira, kugenzura neza umuvuduko wa metallostatike mugihe cyo gusuka, hamwe nigihe cyo kugenzura ubushyuhe bwigihe kugirango wirinde kugabanuka mubyiciro byinshi. Twabonye abakiriya bava mubushoramari bakajya kubira ifuro yatakaye kuri AMS 5387 cobalt alloy pompe ibice-kandi bagabanya igihe cyo kuyobora 37% mugihe batezimbere imbere. Kubera iki? Kuberako uwabitanze mbere yabonaga ifuro nkibisanzwe. Ibyacu bifata nkibintu byambere bisobanutse mumurongo.
Benshi uruganda rwo guta ifuro abakoresha bibanda kubunini cyangwa ubworoherane - amazu manini yimyubakire yicyuma, imitwe yibanze, ibyuma bike. Hafi ya T800 ya cobalt ishingiye ku mavuta cyangwa uruzitiro ruto, uruzitiro rwinshi-rugereranije rusaba ± 0.15 mm gusubiramo inshuro 200 z'uburebure. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dutunganya imashini ifuro ifuro ku bigo 5-axis ya CNC-sibyo kuko irabagirana, ariko kubera ko gutandukana kwa mm 0,08 kuri moderi bihinduranya na 0.12 mm ahantu hashyizweho imashini nyuma yo kunyeganyezwa no kuvura ubushyuhe. Ikigo cyacu cyujuje ISO gikora akazi kangana: umurongo umwe wahariwe amavuta ya cobalt-nikel (AMS 5387, L-605), undi watezimbere ibyuma bya ferritic bidafite ibyuma bikoreshwa mumfatiro ya pompe ya gaz. Buri murongo ufite icyicaro cyacyo kigenzurwa nubushuhe, igishushanyo kibanziriza itanura, hamwe na vacuum ifashwa na sitasiyo isukwa kuri ± 2.5 kPa.
Dore itandukanya irangizwa ryizewe nubushobozi bwa theoretical:
- Gukurikirana ibintu bitangira mbere yo gushonga: Buri fagitire ya T800 igera hamwe na chimie yuzuye yubushyuhe, ingano, na raporo zingana - ntabwo ari urusyo gusa. Turasubiramo ibikoresho byinjira kuri Co, Cr, Ni, W, na C dukoresheje OES, hanyuma tugenera indangamuntu zidasanzwe zahujwe na buri cyiciro.
- Nta "agasanduku k'umukara" karangiza. Ibice bya Cobalt bihita bikemura igisubizo anneal + kuzimya byihuse - nta gukonjesha ikirere, nta guhinduka.
- Imashini ntabwo iri hepfo-yateguwe: Iyo umukiriya yohereje igishushanyo cya GD & T-kiremereye kumubiri wa valve, injeniyeri zacu ntizivuga gusa imashini. Bagereranya gukomera muri MAGMAsoft, ibendera riser ibangamira isura yanyuma ya datum, kandi bagasaba ko hahindurwa uburyo bwo gukuraho ibice byombi - bizigama $ 18.40 kuri buri gice mubunini buciriritse.
Bamwe bavuga ko ifuro yatakaye idashobora guhuza ishoramari ryo kurangiza. Nukuri-kuri Ra 0.8 µm gusaba, ntabwo. Ariko kubuso bukora buzaba hasi cyangwa buzinga uko byagenda kose? Ifuro yatakaye itanga uburinganire bwa microstructural ibice biremereye. Twapimye ubukana bwa 12% munsi yuburebure bwa mm-65 z'uburebure bwa AMS 5387 urukuta rwamazu ya silinderi hamwe n’ishoramari rihwanye - bihujwe neza no gukomera buhoro buhoro mu cyerekezo cyumucanga. Ibyo guhuzagurika bifite akamaro mugihe garanti ya pompe yumukiriya wawe ishingiye kubuzima bwumunaniro kuri 10⁷ cycle.
Niba urimo gusuzuma a uruganda rwo guta ifuro, baza ibibazo bitatu mbere yo gusuzuma ibivugwa: Birashobora kwemeza imiterere yikigereranyo nyuma yo gutwika no gukama? Boba basuka ubushyuhe, urwego rwa vacuum, n'umutwe wa metallostatike kuri buri bushyuhe? Kandi - cyane - bafite amakuru yanyuma yo kugenzura kuri buri casting, ntabwo ari ubufindo gusa? Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibyo ntabwo ari agasanduku. Ni imyitozo ya buri munsi. Twohereje ibyuma birenga 1200 bidasanzwe bya cobalt hamwe n’ibyuma bidafite ingese muri OEM yo muri Amerika ya Ruguru kuva mu 2021 - byose hamwe na raporo za CMM zuzuye, ibiti bivura ubushyuhe, hamwe n’ibikoresho byakurikiranwe muri ingot. Ntabwo ari ukubera ko byoroshye. Kuberako ibice-byingenzi byingenzi bidasiga umwanya wo gutekereza.
Igihe kizaza cyo gutoranya neza ntabwo ari uguhitamo inzira-ni uguhuza neza neza ibivange bikurikirana kumikorere y igice. Ifuro yatakaye hafi-net ishusho yubusugire. CNC yo kugenzura imibare ikora. Ubushyuhe bwo kuvura microstructure ubudahemuka. Kurangiza imikorere yimikorere. Uku kwishyira hamwe-byateguwe, bikozwe, kandi bigenzurwa nka sisitemu imwe-nibyo bihindura ibisobanuro bya casting mubice byemewe-murwego. Kuri ba injeniyeri barambiwe kwiruka ku bipimo by'ibisigazwa, gutinda gutangwa, cyangwa metallurgie idahuye, intambwe ikurikira ntabwo ari indi RFQ. Nisubiramo tekinike hamwe numufatanyabikorwa ufata ifuro nkibikoresho byuzuye, cobalt nkibihinduka bizwi, nigihe cyawe nkigihe cyamasezerano.
