Inganda-yihanganira ibintu byinshi bisaba ibirenze ibintu bisabwa - bisaba imyitwarire, gutunganya ibintu, no kubazwa ibyiciro kuri buri cyiciro. Iyo amazu ya pompe hydraulic yananiwe munsi yumuvuduko wa bar-350, cyangwa cobalt alloy nozzle irashonga nyuma yamasaha 200 muri serivise ya gaz ikarishye, intandaro ni gake gushushanya. Ni ikinyuranyo hagati yo gutoranya kugabanuka no kwitwara neza. Nibintu bitagenzuwe nubushyuhe mugihe cya AMS 5387 yo kuvura ubushyuhe. Ni CMM probe angle idahuye kuri 0.015 mm ya GD&T guhamagara kuri piston silinderi. Twabonye byose uko ari bitatu-kandi tubikosora ntabwo dukoresheje akazi, ahubwo byahujwe gutunganya neza gutunganya uruganda kwicwa.
Kuki Gutera Ubworoherane Atari Kubyerekeranye gusa
Ba injeniyeri benshi bafata gukina nkintambwe "itoroshye" - ikintu cyakozwe nyuma. Iyo mitekerereze irananirana mugihe uburebure bwurukuta butandukanye ± 0.8 mm hejuru ya 420 mm ya pompe yumucanga wa pompe, cyangwa mugihe imihangayiko isigaye iturutse kumukonje utaringaniye igoreka umubiri wicyuma kitagira ingese nyuma yo gutunganywa bwa nyuma. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata gukina nkigikorwa cya mbere cyuzuye - ntabwo aricyo cyanyuma. Ikigo cyacu cyujuje ISO gikora ishoramari risa nu murongo wo guta umucanga, buri kalibariyeri kumiryango yihariye ivanze: amavuta ya cobalt-nikel nka T800 na AMS 5387 arasaba ubukonje buhoro, bugenzurwa; ibyuma byimyanda kubinyabiziga bya winch shafts bisaba kugenzura neza grafite nodule; ibyuma bidafite ingese bikenera inert-kirere isuka kugirango ibungabunge ruswa.
Twemeza imiterere ya geometrie dukoresheje uburyo bwo kwigana - ntabwo ari CAD-kuri-CAM gusa. Kububiko bwa pisitori ya piston pompe, twerekana uburyo bwo kugabanya ubushyuhe mubice 17 byingenzi, hanyuma duhindure ibyapa byibanze hamwe ninjoro yo kwihanganira indangamuntu muri mm 0.12 mm mbere yuko imashini itangira. Nuburyo dutanga casting zigenda neza kurangiza-gutunganya-nta rework, nta scrap, nta kunyerera kuri gahunda.
Kwishyira hamwe guhagaritse: Aho gukina bihurira no gukora imashini
Bamwe mubatanga ibicuruzwa hanze, abandi batanga ibikoresho. Ntanubwo ikora kubice aho uburinganire bwubuso hamwe na microstructure bigomba guhuza. Gucomeka kwa cobalt ntabwo bigoye gusa-biroroshye niba intera ya dendrite irenze 25 µm. Ariko gukabya gukora cyane kugirango wirukane ubuso burangiza rishobora kwibasirwa na microcracks zo munsi. Turabikemura mugucunga impande zombi: itsinda ryacu ryashinzwe gusangira amakuru nyayo yo gusesengura amakuru hamwe na programmes za CNC. Iyo ibisubizo byerekana ibintu byerekana 0,02% hejuru ya karubone mugice cya T800, inzira yacu yo kugenzura ihindura igipimo cyibiryo hamwe nigitutu gikonje - ntabwo ari ukurinda ibyinjijwe gusa, ahubwo ni ukurinda guhangayika gusigara hejuru yubuso bwuzuye.
Uku kwishyira hamwe kugabanya igihe cyo kuyobora 37% kumurongo wo hagati. Icyingenzi cyane, ikuraho gutembera kurwego hagati yo gukina nigice cyanyuma. Twapimye gusubiramo 0.008 mm gutandukana kumwanya kuri 8-ya flange ishusho yibice 120-muri kimwe cya kabiri cya ASME Y14.5 MMB isabwa. Uku guhuzagurika guturuka kubipimo bisangiwe: CMM imwe, gahunda ya kalibrasi imwe, protocole imwe yo gusobanura GD&T murwego rwo gukina QA no gutunganya amakipe ya QA.
Gukurikirana Ibikoresho Byukuri
"Ibikoresho byemewe" ntacyo bivuze niba nimero yubushyuhe ku cyemezo cyurusyo idahuye na casting, cyangwa niba icyitegererezo cyibizamini bya tensile cyakuwe mubice bitandukanye. Dukurikirana buri kilo cyibikoresho fatizo - uhereye kubemerewe gutanga ibicuruzwa byemewe na T800 byinjira mugushonga, gusuka, kuvura ubushyuhe, no kugenzura bwa nyuma. Buri casting itwara QR yanditseho tagi ihuza ibisobanuro byuzuye: ibigize imiti kuri ASTM E353, ingano yintete kuri ASTM E112, gushushanya amakarita yambukiranya ibice, hamwe na raporo ya CMM kubintu byose byingenzi.
Kubakiriya ba peteroli na gazi bisaba kubahiriza API 6A, twongerera ubushobozi bwo gupima imikorere: buri cyuma cyumuvuduko gikora hydrostatike gihamya ya 1.5 × igitutu cyagenwe, hamwe nugusoma ibipimo byanditse kuri buri gice. Niba umukiriya abajije ubuzima bw'umunaniro ku gice cya pompe ya AMS 5387, dukurura igiti nyacyo cy'ubushyuhe, tukongera kubara umuvuduko ukabije, kandi tugahuza n'amashusho ya SEM yamenetse kuva ibice byemejwe mbere. Nta bitekerezo. Nta kurenganurwa. Ibimenyetso gusa.
Ukuri-Isi Yuzuye Itangirana nibiganiro nyabyo
Ntabwo tugurisha serivise za casting-dukemura uburyo bwo gutsindwa kurwego. Mugihe hydraulics yu Burayi OEM yatangaje ko 18% yanze kumazu ya silinderi kubera bore ovality, ntitwigeze dusubiramo uburyo bushya. Twasuye umurongo wabo wo guterana, dupima ubwiyongere bwubushyuhe bwibice byabo byo gushyingiranwa, tunongera gushushanya imiterere yimbavu ya casting kugirango turwanye kugoreka mugihe cyihariye cyicyubahiro. Igisubizo: 99.2% umusaruro-wambere wambere, impinduka zeru kubikoresho byabo bihari.
Itandukaniro riri hagati ya a gutunganya neza gutunganya uruganda n'urufatiro. Niyo mpamvu abakiriya bo muri Amerika ya ruguru, Ubudage, na Singapore batwoherereza ibishushanyo bya GD & T-biremereye-ntabwo ari RFQ gusa. Bazi ko tuzashyiraho amabendera yingaruka zo gukora mbere yuko ibikoresho bitangira: umuhamagaro wa mm 0.005 kuri 300 mm hejuru yumucanga? Tuzasaba igitekerezo cyo gushora imari aho. T800 idasanzwe ya alloy nozzle hamwe na radiyo y'imbere munsi ya 0.3 mm? Tuzigana isuri iterwa no gutwarwa nisuri kandi dusabe kuvura HIP yaho.
Sura https://www.tsingtaocnc.com gusubiramo ibyemezo byubushobozi byemewe byubushakashatsi bwa cobalt alloy casting, gukuramo GD&T ibisobanuro byo gusobanura, cyangwa gusaba isubiramo ryubusa kubice bikurikira byo kwihanganira byinshi. Precision ntabwo igerwaho mubwigunge-yubatswe aho siyanse yubumenyi ihura na disipuline yo gutunganya, kandi aho buri bisobanuro bifite ibisobanuro bifatika.
