Inganda-yihanganira cyane ntabwo itangirana na gahunda ya CNC cyangwa imashini ya casting. Bitangirana nicyemezo: gufatanya ninganda zikora inganda zikora neza zifata ingamba zihamye, guhuza metallurgjique, no kwizerwa kumikorere ntabwo ari intego - ahubwo nkibidashoboka.
Twabonye imishinga myinshi ihagaze kuri prototype-ntabwo bivuye mubishushanyo mbonera, ahubwo bivuye mubushobozi budahuye. Umukiriya mu Budage yigeze kutwoherereza igishushanyo mbonera cya AMS 5387 cobalt alloy pompe amazu nyuma yo kugerageza inshuro eshatu zananiranye ahandi. Ikibazo nticyari kwihanganira guhamagarwa (± 0.01 mm kuri bores zikomeye) cyangwa kurangiza hejuru (Ra 0.4 µm). Kwari ukugoreka ubushyuhe mugihe cyo kuvura ubushyuhe-butagenzuwe mbere, ntibigaragara kugeza ubugenzuzi bwa nyuma bwa CMM. Nibwo twatahuye: kwihanganira cyane ntabwo ari imibare ikaze gusa. Nukugenzura buri variable yimura iyo mibare.
Kwishyira hamwe Vertical Numurongo wambere wo kugenzura kwihanganira
Abatanga ibicuruzwa benshi batanga casting, gutunganya, cyangwa kurangiza. Ibyo birema ibice bitatu bitandukanye - hamwe nuburyo butatu bwo kugendana microstructural, kongera gukosora amakosa, cyangwa imibare idahwitse. Mu kigo cyacu cyujuje ISO muri Qingdao, imyanda ya cobalt-nikel iva mubushoramari ikajya mu ruganda rwinshi-rutavuye mu bicuruzwa. Twebwe imashini ya silinderi yububiko butagaragara neza muburyo bwo guhuza ibyuma-nta gushiraho kabiri, nta guhinduranya datum. Kubice bya pompe ya piston isaba kwibanda munsi ya 0.008 mm hejuru ya mm 300 z'uburebure, ubwo buryo bukomeza kugabanya ikosa ryakozwe hejuru ya 60% ugereranije nabacuruzi bakurikirana.
Ibi ntabwo ari theoretical. Mu mushinga umwe wa peteroli yo muri Amerika ya Ruguru, twatanze imibiri 127 yumuvuduko wa valve - byose biri muri mm 0.005 mm kuri diameter yintebe, byose bikaba bishobora gushyuha kubushyuhe bumwe bwa T800 yemewe. Nigute? Kuberako itsinda ryacu ryashingiweho rihindura ubushyuhe bushingiye kubisesengura ryigihe-nyacyo, abakanishi bacu bakoresha mugikorwa cyo kugerageza kwishyura indishyi zo kwambara mbere yuko igera kuri mm 0.002, kandi laboratoire yacu ya metero yemeza buri kintu cyose kirwanya ASME Y14.5 GD&T ibisabwa-ntabwo ari ibipimo byizina gusa.
Ubuhanga bwa Superalloy Bisobanura Kumenya icyo Ubwoko butavuga
AMS 5387 ntabwo "bigoye gukora imashini." Igipimo cyacyo cyo gukomera kizamuka hejuru ya 350 HB. Ibikoresho bisanzwe bya karbide byavunitse; gukonjesha gutemba bitera gutera kwisubiramo. Amaduka amwe yitabira kugaburira buhoro no gukuraho ibicuruzwa biremereye - hanyuma ukibaza impamvu ibice bitera imbaraga zo kugabanya imihangayiko.
Ntabwo dufata ibinyobwa bya cobalt nkibidasanzwe. Turabifata nkibikorwa bikora. Isomero ryibikoresho byacu birimo imyitozo ya PCD ya nozzles ya T800, urusyo ruvurwa na cryo yo gusya kugirango uhore ucomeka mumacomeka ya AMS 5387, hamwe ningamba zo guhuza n'imihindagurikire y'ikirere zituma imitwaro ya chip iri hagati ya 5% muburebure butandukanye bwurukuta. Kunegura cyane: twemeza buri bushyuhe bwimbaraga zingana nubunini bwimbuto * mbere yuko * gutunganya bitangira-ntabwo nyuma. Kuberako gutandukana kwa 2% mubirimo cobalt bihindura kwaguka kwubushyuhe bihagije kugirango uhagarike 0.012 mm ikwiranye.
- AMS 5387 ibice byakorewe hamwe sub-0.003 mm gusubiramo hejuru y'ibice 50
- T800 alloy center shaft umuzingo ugeraho Ra 0,25 µm ubusugire bwubuso hatabayeho gutunganya imashini
- Cobalt alloy nozzles irengana Igenzura rya ultrasonic 100% kubwimbere imbere-ndetse no kuri mm 12 z'ubugari
Ubwiza ntibugenzurwa-Bwakozwe muri
Inganda zimwe zikora ubugenzuzi bwingingo ya mbere. Turakora mbere- * ibikoresho * ubugenzuzi. Igiceri cyose, akabari, cyangwa ingot bigera hamwe na raporo yikizamini cyuzuye. Twambukiranya chimie dukoresheje OES spectroscopy, kugenzura microstructure dukoresheje ibice byasesenguwe, hamwe namakarita yerekana ubukana bwambukiranya ibice. Kubera iki? Kuberako fagitire "yemejwe" AMS 5387 irashobora kwerekana itandukaniro rya 15% gukomera kuva hejuru kugeza kuntambwe - bihagije kugirango uhagarike ibizabaho byubuzima kandi bitere guhangayika.
CMM yacu ntabwo iparitse mubyumba bigenzurwa nikirere. Yinjijwe muri selile yo gutunganya-gupima bore kuzenguruka * hagati ya * gukomera no kurangiza. Kugereranya neza kugenzura umugozi uyobora neza kumateraniro mugihe ibice bikiri bishyushye, bifata imyitwarire yo kugabanya ubushyuhe. Igenzura ryanyuma ririmo ibizamini bikora: indangagaciro zumuvuduko zikora 1.5 × zafashwe hydraulic muminota 30; winch shafts izunguruka kuri 2200 RPM kuri dinamike iringaniza.
Gukurikirana ntabwo ari agasanduku. Ni urunigi: numero yubushyuhe bwibintu → gutora → verisiyo ya gahunda ya CNC ID ID ID ID ID ID ID ID ID ID Niba umukiriya yerekana ibidasanzwe, twubaka inzira yose muminota 90 - ntabwo ari iminsi.
Gutanga kwukuri kwizerwa bitangira mbere ya PO
“Urashobora gukora ibi?” ni ikibazo cya mbere. "Ni ibihe bintu bishobora guteza ibyago byinshi - kandi ni gute dushobora kubishyira mu kaga * mbere yo gutema ibyuma?" ni i. Niyo mpamvu isuzuma ryubuhanga ryacu ririmo kwemeza GD&T, gutanga ibitekerezo ku bice bito-bito, hamwe no kwigana ubushyuhe bwa geometrike ikunda kugoreka. Turashyira ahagaragara ibibazo bishobora gukonjeshwa nko gukonjesha asimmetrike mumfatiro ya pompe cyangwa gufunga-guterwa no gutandukana mumazu maremare ya silinderi-mbere yuko inzira yambere ikorwa.
Dutanga ibicuruzwa biciriritse (50-500 pcs) mubyumweru 12-18 - ntabwo ari ukubera ko dutinda, ariko kubera kugabanya ingaruka, ntabwo ari igihe. Prototypes yohereza mubyumweru 4-6 hamwe nububiko bwuzuye bwo kugenzura. Ntibitangaje. Nta gusubiramo imirimo. Gusa ibice bikora nkuko byasobanuwe, mugihe, mumasoko yisi yose - kuva hydraulic OEMs muri Wisconsin kugeza kuri pompe ya offshore muri Singapore.
Kuri ba injeniyeri bagaragaza ibice aho ± 0.005 mm bisobanura itandukaniro riri hagati yubudakemwa bwa kashe no kunanirwa kw’ibiza, gufatanya n’uruganda rukora imashini zisobanura neza guhitamo kugenzura ubwumvikane. Bisobanura kwizera ko cobalt alloy idakozwe gusa-irabujijwe. Ukwo kwihanganira ntikwirukanwa-kwubatswe. Ko buri gice kivuga inkuru imwe: ibyiringiro byukuri, ubudahemuka bwibintu, kwitegura gukora.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikorera kuri iryo sangano-aho superalloy igoye ihura ningero zingana ninganda. Ibikorwa byabo byerekana ko gukora-kwihanganira cyane bidasobanurwa nibikoresho byihariye. Byasobanuwe nibibaho hagati yicyemezo cyibikoresho na raporo yanyuma yubugenzuzi. Kandi niho hatangirwa kwizerwa nyako.
