Birakenewe ibicuruzwa byabugenewe guterera hafi y'uruganda inkunga - ntabwo itanga gusa, ahubwo ni umufatanyabikorwa wa tekinike wunvise umuvuduko wamazi wa hydraulic, cobalt alloy brittleness, nimpamvu guhamagarwa kwa GD&T kumazu ya pompe bidashobora "kugereranywa"? Ntabwo urimo gushakisha umucuruzi. Urimo gushakisha umuntu wafashe AMS 5387 cobalt alloy nozzle mu ntoki, apima microstructure ya as-cast munsi ya SEM, kandi ahindura umubyimba w'ishoramari * mbere yo gusuka - kuko ubushize, itandukaniro rya mm 0,12 ryatumaga ubushyuhe bwumuriro butaragera muri serivisi zumurima.
Twabibonye: OEM yo muri Amerika ya ruguru yihutishije pisitori ya piston pompe amazu yubatswe kugirango yuzuze igihe ntarengwa cyo mu cyiciro cya 4. Uruganda rwabo rwasubiyemo ibyumweru 14 - kandi rutanga ibyiciro bitatu hamwe nubushake kuri porte ya port. Gukosora ntabwo byari byihuse kohereza. Yarimo atekereza ku gishushanyo mbonera, yerekana ubushyuhe bwa ceramic kugeza kuri 950 ° C, no kugenzura uburyo bwo kwigana ibintu bifatika byerekana amashusho yerekana ubushyuhe buturuka kumasuka. Ngiyo itandukaniro riri hagati yo "guterera hafi yanjye" na ibicuruzwa byabugenewe guterera hafi y'uruganda ikorera ku masangano ya metallurgie, geometrie, no kwizerwa kumikorere.
Kuki "Hafi yanjye" idahagije-Niki Mubyukuri mubijyanye no gukina neza
"Hafi yanjye" byumvikana neza - kugeza igihe winch center ya shaft roller yananiwe kurwego rwa 72% yumuriro kuko umusenyi utera ingano ntiwigeze uhuza na torsional stress vector. Kuba hafi ntacyo bivuze bidafite ubushobozi bune butaganirwaho:
- Indero y'ibikoresho.
- Kwishyira hamwe: Gutera no gutunganya CNC munsi yinzu - bityo itsinda rimwe rigenzura amafaranga yo kugabanuka, kugabura ibicuruzwa, hamwe nindishyi zo kugoreka ubushyuhe
- Gushyira mu bikorwa: Igenzura rya CMM * nyuma * yo kugabanya imihangayiko, ntabwo nyuma yo gutunganyirizwa gusa-no gupima optique ibice byimbere aho iperereza ritazakwira
- Kwemeza imikorere: Inzu yo gupima igitutu kuri 1.5 pressure igitutu cyakazi, ntabwo ari ukwinjira gusa
Amaduka menshi yo mukarere arusha umwe cyangwa abiri. Bake bayobora bose uko ari bane badasezeranye-kandi buri ntoki yongera ibyago. Ntabwo dusohora inzira yibanze. Mugihe umukiriya yohereje igishushanyo cya T800 cobalt gishushanya hamwe na ± 0.005 mm kwihanganira kuzenguruka kuri bore ya mm 12, abajenjeri bacu bashinga imishinga basuzuma igishushanyo mbonera * kandi * abakanishi bacu bemeza ibikoresho byifashishwa - byose mbere yo kuvuga.
Aho Ibishingwe bisanzwe bikubita aho bigarukira - nuburyo tubihuza
Bamwe bavuga bati: “Koresha uruganda rukora urugo gusa. Itumanaho ryihuse, nta gasutamo itinda.” Nukuri - ariko gusa mugihe igice cyawe kidasaba AMS 5387 cobalt alloy, fondasiyo ya pompe yumusenyi hamwe numuyoboro ukonjesha, cyangwa ibyuma bisaba ASTM A48 Icyiciro 65-70 imbaraga zingana * wongeyeho * imashini ifunga imashini ifata Ra 0.4 µm.
Ibishingwe bisanzwe ntibikunze kubarwa T800 alloy ingots. Ntabwo bakora vacuum-arc remelt (VAR) verisiyo kuri buri bushyuhe. Ntibagumana ibintu byuzuye bikurikirana kugeza kuri numero ya electrode. Kandi ntibigera bashira isesengura rya GD&T muburyo bwo gukora-kuburyo iyo ubonye casting yambere, imiterere ya datum idahuye neza, guhatira gukora cyane cyangwa gusiba.
Turabikora. Buri kintu cyose cobalt-nikel gitangirana nibikoresho byemewe byurusyo. Umucanga wose ukorerwa igenzura rya radiografiya kuri ASTM E94. Ubuso bwose bwakorewe imashini ibona igenzura rirangiye - ntabwo ari ubukana gusa, ahubwo ni radiyo ihamye ahantu 32. Nuburyo twohereza ibicuruzwa byumuvuduko unyura 100.000-cycle umunaniro-umunaniro-nta murima numwe watsinzwe mumezi 27 ashize.
Ibisohoka-Byisi-Byose: Ibyo Wakiriye Mubyukuri
Ibi ntabwo ari theoretical. Dore icyasize ikigo cyacu cya Qingdao buri cyumweru:
- Ibice bya sisitemu ya Hydraulic: Inzu ya silinderi hamwe na galeries yimbere imbere yatewe kuri mm 0,15 mm, hanyuma CNC ikorwa kugirango ikomeze kwibanda hagati ya bore na flange iri muri mm 0,02
- Ibikoresho byubwubatsi.
- Ibikomoka kuri peteroli na gaze.
- Amateraniro.
Nta kwihanganira "sample-only". Nta "guhindura imikorere." Ibigenzurwa kuri prototype casting bifunzwe muri gahunda yo kugenzura gahunda yo gutumiza amajwi. Niyo mpamvu 68% byabakiriya bacu basubiramo bashyira amajwi aringaniye (50-500 pcs) muminsi 90 uhereye kubitangwa bwa mbere.
Intambwe Zikurikira: Kuva Gushushanya Kugeza - Nta Gukeka
Niba ufite igice gisaba gutera neza - cyane cyane muri cobalt-nikel, amavuta akomeye, cyangwa ibyuma birwanya ruswa - tangira hano:
- Sangira dosiye yawe 2D / 3D. Tuzagarura ibitekerezo byakozwe mumasaha 48-harimo ibitekerezo byinjira, amafaranga yimigabane, hamwe nuburyo bwo kuvura ubushyuhe
- Kugaragaza ibisabwa mu mikorere: Ibi ni umutwaro uhagaze? Umuvuduko ukabije? Isuri yo mu bushyuhe bwo hejuru? Duhuza guhitamo ibikoresho no gutunganya intambwe kubikorwa - ntabwo ari spes gusa
- Emeza ibikenewe gukurikiranwa: Ubushyuhe bwuzuye? Raporo y'ibizamini? NDT inyandiko? Twubaka inyandiko mubikorwa-ntabwo ari nkibitekerezo
Ntukeneye "uruganda hafi yanjye." Ukeneye a ibicuruzwa byabugenewe guterera hafi y'uruganda ifata igice cyawe nkibikoresho byingenzi-ubutumwa-ntabwo ari ibicuruzwa. Ibyo bivuze kuvuga ururimi rwawe: ntabwo ari "guta ibyuma" gusa, ahubwo "A48 Icyiciro cya 65 hamwe na matrike ya pearlitike yemejwe na metallography." Ntabwo ari "umwanda," ahubwo "S32750 irimo ferrite 42-48% kuburyo bwa ASTM A923 C."
Urwo rwego rwihariye ntirubaho kubwimpanuka. Bibaho mugihe metallurgiste, injeniyeri zashinzwe, hamwe nabashinzwe porogaramu za CNC bicaye mucyumba kimwe - bagasuzuma ibishushanyo byose hamwe. Ngiyo amahame yacu. Nibyo bituma "hafi yanjye" bifite ireme.
