Iyo ba injeniyeri bagaragaje a uruganda rukora shaft, ntabwo bashakisha gusa ibintu bizunguruka-bahitamo umufatanyabikorwa ushoboye kwihanganira ± 0.005 mm kwihanganira munsi ya 300 MPa hydraulic imizigo, kurwanya kwangirika ahantu habi cyane, no gutanga ibikoresho byuzuye kugeza kumubare wubushyuhe. Urwo rwego rwo kubazwa gake ruva mububiko rusange-bugenewe ibyuma.
Twabonye imishinga myinshi ihagaze kuri prototype kuberako igiti - cyagenewe guhuza umuvuduko mwinshi murwego rwo gupima pompe ya centrifugal-cyashize mugihe cyo kuvura ubushyuhe. Cyangwa kunanirwa kwinyeganyeza nyuma yamasaha 42 kubera micro-porosity itamenyekanye muri casting core. Izi ntabwo arizo ngaruka. Nibisubirwamo byananiranye twasuzumye kumugabane wa gatatu, muri sisitemu ya winch ya peteroli, moteri ya hydraulic actuator, hamwe na pompe yimiti ikabije.
Precision itangirira aho metallurgie ihura na geometrie
Igiti kigororotse ntabwo ari silinderi yoroshye. Nibikorwa bikora: umwe mubashakanye barangiza bafite isiganwa ryuzuye-ryuzuye; igice cyo hagati gitwara amenyo yumugongo akomeye yanduza umuriro mugihe cyo kwikunda wenyine; ibinyuranyo byanyuma bitandukanijwe muburyo bukomatanyije bwa rotor. Gutandukana kwose, kwibanda hejuru (Ra ≤ 0.4 µm), cyangwa gukwirakwiza impungenge zisigaye zikwirakwira nkurusaku, kwambara, cyangwa umunaniro ukabije.
Niyo mpamvu guhitamo ibikoresho bidashobora gutangwa kuri datasheet. Amavuta ya Cobalt-nikel nka AMS 5387 atanga imbaraga zo kurwanya ruswa no gukomera - ariko bakora imashini kuri 1/3 cyo kugaburira ibyuma 4140 kandi bagasaba gushiraho, ibikoresho bya kirogenike, no kugenzura ubushyuhe bwigihe. T800 ishingiye kuri shitingi isaba gushora imari hamwe nububiko bwa ceramic, hanyuma hagakurikiraho HIP (gukanda isostatike ishyushye) kugirango ufunge icyuho cyimbere - hanyuma CNC ifungura imashini zifite sub-micron axis ihagaze. Gusiba intambwe iyo ari yo yose bibangamira ubunyangamugayo.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri shitingi nka sisitemu ikomeye-ntabwo ari igice cyibicuruzwa. Ikigo cyujuje ISO muri Qingdao gihuza casting, gutunganya imirongo myinshi, hamwe no kurangiza hejuru yinzu. Nta ntoki. Nta kwimura icyiciro. Iyo umukiriya yohereje ibishushanyo bya GD&T kuri mm 320 z'uburebure, mm 65 z'umurambararo wa mm 65 hamwe na 12 ° ya tekinike hamwe na HRC 58-62, uburebure bwikibazo, itsinda ryacu ryemeza ko ryakozwe * mbere yo kuvuga - gushyira ahabona ahantu hashobora kuganirirwa, hagashyirwaho uburyo bwiza bwo kuvura ubushyuhe hamwe nigishushanyo mbonera cya fayili.
Kwishyira hamwe bihagaritse ntabwo byoroshye-ni kugenzura
Bamwe mubatanga isoko batanga casting, hanyuma bagakora imashini, hanyuma bakohereza ibice mumaduka yabandi. Buri ntoki itangiza ibintu bitandukanye: imiterere yintete idahuye uhereye kubikorwa byubushakashatsi butagenzuwe, gutembera kurwego rwo kongera guhuza, kwanduza hejuru mbere yo gusya bwa nyuma. Twapimye kugera kuri 18 µm kwiruka gutandukana hagati ya casting yinjira hamwe na shaft yarangiye mugihe inzira zacitsemo ibice.
Ibikorwa byacu bihagaritse bikuraho ibyo byuho:
- Guterera mu nzu.
- Gukora ibikoresho byanditse: 5-axis CNC ibigo bifite ibikoresho bizima, iperereza rya Renishaw, hamwe no kugenzura CMM kuri diameter zikomeye
- Kurangiza ufite intego: Amashanyarazi ya nikel adafite amashanyarazi kugirango arwanye kwambara, kurasa hejuru yubushyuhe bwo hejuru, cyangwa indorerwamo-indorerwamo ya kashe ya interineti - ikoreshwa gusa aho imikorere isaba
Ibi ntabwo bijyanye no kugabanya ibiciro. Nukurandura impinduka zangiza gusubiramo. Igiti cyakorewe imashini itigeze ikorwa na lazeri mu mezi 9 irashobora guhura n’ibihanganirwa byacapwe uyu munsi-bikananirana ubugenzuzi ejo. Turasubiramo buri masaha 72 yumusaruro. Buri gice gitunganyirizwa ubushyuhe gikorerwa Brinell na Rockwell. Igiti cyose cyarangiye kibona 100% optique yo kugenzura inenge no kwemeza CMM kurwanya moderi yambere ya CAD.
Kuki "ibipimo" bidasanzwe bidakoreshwa mubutumwa bukomeye
"Gusa kora kuri ASTM A494 Icyiciro cya M35-1" - icyo cyifuzo ntacyo kitubwira kubyerekeye ibahasha yawe ikora. Uru rufunzo ruzunguruka kuri 4200 RPM imbere yimikorere ya valve? Izunguruka inshuro 12,000 buri cyumweru muri gari ya moshi ivanga umubumbe wa sima? Bizabona rimwe na rimwe guhura na H₂S cyangwa amazi yo mu nyanja ya chlorine?
Turabaza ibyo bibazo - ntabwo ari ukubera ko twishimiye impapuro, ariko kubera ko igisubizo gihindura byose: guhitamo icyiciro cyibikoresho, kuvura ubushyuhe bwo gufata igihe, uburyo bwo gupima butangiza (UT na MPI), ndetse no gupakira protocole (vapor-phase inhibitor kubyoherezwa hanze). Pompe imwe yu Burayi OEM yamenye ibi bigoye: icyuma "gisanzwe" cyuma kitagira ingese cyangirika mugihe cyibyumweru 3 mugice cyo gutera inshinge. Hindura kuri AMS 5387 hamwe na carbide ikwirakwizwa ikwirakwiza ubuzima bwa serivisi kugeza kumezi 18.
Ihinduka ntabwo ryari amarozi. Byaturutse ku isuzuma ryubuhanga-aho twashushanyije uburyo bwo kunanirwa kwabo, guhuza amakuru yerekanwe kumikorere ya NACE MR0175, kandi twemeza ibisobanuro bishya binyuze mugupima ubuzima bwihuse muri laboratoire yacu.
Reba ibirenze gushushanya - reba indero yo gutanga
Igikoresho cya tekiniki cyuzuye ntacyo bivuze niba gihageze ibyumweru bibiri bitinze gutangira. Cyangwa niba ibice 10 byambere byatsinze ubugenzuzi-ariko 11 birananirana kubera inzira idafite ibyangombwa. Dushyira mu bikorwa imyitozo itanoze: Kanban igenzurwa nibikoresho fatizo byo kubika, gutondekanya imirimo ikurikirana hamwe na bariyeri ya QC yashyizwemo, hamwe nigihe cyo gutanga umusaruro mugihe gikwiye kubakiriya.
Kuri prototype ikora, twohereza raporo yingingo ya mbere hamwe namakuru yuzuye ya metrology-harimo n’ibiti byo kwagura ubushyuhe. Kubicuruzwa bito bito, dufata ububiko bwa fagitire zemewe kugirango dukureho amasoko atabangamiye ubwoko bwibintu.
Niba ukeneye a uruganda rukora shaft ifata ituze rishingiye ku gipimo nkibidashobora kuganirwaho, guhuza metallurgjiya nkibisabwa, no gutanga ku gihe nkibimenyetso byerekana imyitwarire - bitangirana inama na tekiniki, ntabwo ari RFQs. Sura https://www.tsingtaocnc.com kugirango usuzume ibisobanuro byubushobozi, ibyemezo bifatika, hamwe nincamake yimanza zisaba isi. Igiti ugaragaza uyumunsi kizasobanura sisitemu yo kwizerwa kumyaka. Hitamo ukurikije.
