Iyo ba injeniyeri bagaragaje a yatakaye uruganda rukora ibyuma, ntibashakisha gusa ibyuma byasutswe mubibumbano. Bakeneye gutekana kurwego munsi ya 300 MPa hydraulic. Kugenzura microstructure muri AMS 5387 cobalt alloy nyuma yo kuvura ubushyuhe. Zeru yuzuye muri mm-120 ya diametre ya pompe ya pompe ya silinderi izenguruka kuri 1.800 RPM mugihe ushizemo ibishishwa. Nibyo byukuri bikora-ntabwo ari umutwe wamakuru.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora kimwe muri ibyo bikoresho-byemewe na ISO, bihagaritse, kandi byubatswe muburyo bwo kunanirwa imikorere. Twashize amajwi ya T800 ya pompe zo gutera inshinge aho ubuso bwa mm 0,05 butera isuri yibiza. Twakoze imashini ya pompe ya piston hamwe na GD&T guhamagarwa kurenza ± 0,015 mm kuri bore ikomeye yo gufunga - kandi twatanze ingingo ya mbere kuri gahunda eshatu zikurikirana za OEM yo muri Amerika y'Amajyaruguru. Ubu ntabwo aribwo bushobozi. Nibisubirwamo bisubirwamo munsi yimbogamizi zisi.
Kuberiki yatakaye ibishashara bishashara birananirana-keretse iyo ugenzuye ibice bine
Kunanirwa kwinshi bikurikirana kuri kimwe mu byuho bine: kudahuza ibintu, kugoreka imiterere, gutakaza ibishishwa byuzuye, cyangwa kudahuza ubushyuhe mugihe cyo gukomera. Ibishingwe bisanzwe bifata izi nkintambwe yihariye. Ku kigo cyacu cya Qingdao, bahujwe nibihinduka.
- Gukurikirana ibintu bitangira mbere yo gushonga: Buri AMS 5387 cyangwa F22 ingot idafite ingero zitwara raporo yikizamini kandi ikongera kugenzurwa hakoreshejwe OES spectroscopy imaze kwakirwa. Twanze ibyiciro bifite> 0,02% gutandukana na sulferi - kabone niyo byaba bitarenze ASTM A995 - kubera ko bifitanye isano itaziguye no gutanyagurika gushyushye mumibiri ya rukuta.
- Imiterere ya geometrie ifashwe kuri ± 0.03 mm: Dukoresha ibyuma bya aluminiyumu ya CNC yakozwe na CNC-ntabwo ari imashini yacapishijwe 3D-muburyo bwo gushora imari mukubyara umusaruro mwinshi. Kubera iki? Kugabanuka kwa resin biratandukana nubushuhe nigihe cyo gukira; aluminium ntabwo. Umukiriya umwe wa hydraulic yu Burayi yagabanije igipimo cyo kwangwa kuva kuri 4.2% kugeza kuri 0.3% nyuma yo kwimukira muri sisitemu yacu.
- Imbaraga z'igikonoshwa zirapimwa - ntabwo zifatwa. Ibishishwa bimara amasaha 24 yikime-bigenzurwa no gukama mbere yo gutwikwa. Kureka iyi ntambwe bitera micro-crack ziba ubusa munsi yubutaka bwa X-ray ya nyuma.
- Icyitegererezo cyo kwerekana icyerekezo gitera igishushanyo: Dukoresha amashusho ya MAGMAsoft kuri buri cyuma gishya - cyane cyane kumanota adafite ingese nka CF8M aho gutandukanya dendritic bigira ingaruka kumurwanya. Sisitemu yo kwinjirira neza ntabwo yongerewe igihe gusa, ahubwo ni ugukomera kwerekeza kuri risers. Nuburyo tugera kumvikana muri 85-mm-yuburebure bwa pompe idafite HIPing ya kabiri.
Aho gutunganya bihura na casting: inyungu ya Hybrid
Gutakaza ibishashara byonyine ntibikemura ikibazo. Nta nubwo CNC ikora. Ibisobanuro nyabyo biza aho bihurira-kandi niho guhuza vertical bitanga ROI ipimwa.
Twataye umubiri wibyuma bitagira umuyonga hamwe na mm 2,5 zamafaranga yo gutunganya mumaso yo gufunga, hanyuma tukabirangiza kumashini 5-axis DMG Mori ifite ibikoresho bya Renishaw PH10M. Ibipimo by'ingenzi bigenzurwa hagati-hakoreshejwe gukoraho-trigger CMMs yahinduwe kuri ISO 10360-2. Igisubizo? Igipimo cyerekana gusoma kiguma munsi ya 0.008 mm hejuru ya mm 150 z'uburebure - nta gusya. Uruganda rukora pompe yo mu majyepfo yuburasirazuba bwa Aziya rwagabanije igihe cyarwo cyo kuyobora 37% muguhuza casting no kurangiza kudukorera hamwe aho gucunga abatanga ibicuruzwa bibiri.
Ibi ntabwo bijyanye no korohereza. Nijyanye no gukuraho ikosa rya stack-up. Iyo utanga ibicuruzwa byawe afite mm 0.3 mm naho iduka ryimashini rifite ± 0.1 mm, kwihanganira geometrike mubi ± 0.4 mm. Dufata inzira zombi munsi yinzu - kandi tugenzura ihererekanyabubasha hagati yabo. Niyo mpamvu indangagaciro zacu zumuvuduko zihura na API 6D kumeneka Icyiciro A nta gukubita kabiri.
Ibyo abakiriya babaza mubyukuri - nibyo bakeneye mubyukuri
“Urashobora gutera ibyuma bitagira umwanda?” ni gake ikibazo gikwiye. Ibyukuri biza nyuma:
- “Iyi nzu 316L izagumana imbaraga z'umusaruro uri hejuru ya 425 ° C nyuma yo gutera + igisubizo anneal?” Yego - hamwe nubushakashatsi bwuzuye bwo kuvura ubushyuhe hamwe namakuru yikizamini cya buri cyiciro cya ASTM A370 cyemejwe.
- “Urashobora gufata uburebure bwa mm 0.005 kuri 300 × 200 mm yo kwishyiriraho?” → Gusa iyo tuyikoresheje imashini nyuma. Gushora imari byonyine ntibizatanga ibyo. Tuzakubwira imbere-kandi twerekane igishushanyo mbonera gishoboka.
- “Ushyigikiye PPAP Urwego rwa 3?” → Yego, harimo raporo zingana hamwe na CMM ingingo yibicu, ibikoresho bifatika, hamwe na FMEAs. Ariko kandi dushyira ahagaragara ibimenyetso biranga GD&T bidahagaze neza muburyo bwa mbere - kandi tugatanga ubundi buryo bwo kugenzura.
Ntabwo tugurisha "guta ibishashara byabuze." Tugurisha ibyiringiro bikora kubice bigomba kubaho amasaha 20.000 muri serivisi ya peteroli cyangwa imyaka 15 muri sisitemu ya hydraulic marine. Ibyo bisaba kwanga 7.3% byimigabane ya cobalt-nikel yinjira - atari ukubera ko yananiwe kugaragara, ariko kubera ko ingano yingano yayo igwa hanze yidirishya ryatunganijwe.
Guhitamo uruganda rwatakaye rwibishashara bisobanura guhitamo umwirondoro wawe
Amagambo make ahendutse asa neza kugeza igihe winch center shaft roller ivunika mugihe cyo kugerageza imitwaro. Kugeza igihe cobalt alloy plug icomeka nyuma yamasaha 400 yo gukora - ntabwo 5.000 yagenwe. Kugeza igihe ibipimo bigenda byongera imbaraga kuri 22% ya pompe ziteranijwe.
Itandukaniro riri mubikorwa byanditse kugenzura - ntabwo bisaba ibicuruzwa. Kugenzura ibintu mbere yo gusuka - ntabwo nyuma. Muri GD & T-uzi gushushanya - ntabwo ari CAD gusa. Mugenzuzi protocole ihujwe nuburyo bwo kunanirwa - ntabwo ari urutonde rusange.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yubaka iyo disipuline muri buri cyiciro. Ntabwo ari inyongera. Ntabwo ari amahitamo. Nka shingiro.
Niba porogaramu yawe isaba ibice byicyuma neza aho imikorere idashobora kuganirwaho - aho "gufunga bihagije" bisobanura gusiba, gutinda, cyangwa ibyago byumutekano - ukeneye ibirenze gushinga. Ukeneye umufatanyabikorwa ufata buri casting nkuko izakorera imbere module yo kugenzura munsi yinyanja ya metero 3.000. Nibisanzwe twe injeniyeri. Ninimpamvu abajenjeri bagaruka-na none-kuri a yatakaye uruganda rukora ibyuma ipima intsinzi muri zeru zananiwe, ntabwo zitangwa ku gihe gusa.
