Iyo injeniyeri muri Amerika ya ruguru cyangwa Uburayi zishakisha gushora imari mu Bushinwa, ntibashakisha gusa umusaruro uhendutse-barimo gushakisha ituze ryikigereranyo munsi ya 120 ya hydraulic ya hydraulic ya MPa, guhuza microstructural guhuza ibice 500, hamwe no kutihanganira zeru kubi muri cobalt alloy nozzles. Nibyo byukuri inyuma yikibazo. Twabonye amatsinda yo gutanga amasoko yanze abatanga ibintu bitatu bikurikiranye - ntabwo arenze igiciro, ariko kubera ko uburebure bwurukuta rwatandukanijwe mm 0.35 mm kuri 42 mm-ya diametre ya piston pompe ya pompe. Precision ntabwo ihitamo muri sisitemu ya hydraulic yambaye cyane. Nibyingenzi.
Kuki "Ishoramari Ritera Ubushinwa" ritakiri icyemezo gusa
Imyaka itanu irashize, "gushora imari mu Bushinwa" byasobanuraga guta umucanga hamwe na CNC gukoraho-no gukora kenshi. Uyu munsi, bivuze ko ibishingwe byemewe na ISO 9001 bikoresha inzira yuzuye yatakaye-ibishashara: gutera ibishashara ku gipimo cya mm 0,05 mm kwihanganira, igikonoshwa ceramic kirasa kugeza kuri 1100 ° C, kugenzura isuka ifashwa na vacuum, hamwe no kuvura ubushyuhe nyuma yubushakashatsi byagenzuwe nisesengura ryakozwe. Ihinduka ryaturutse kubisabwa - ntabwo ari politiki. Hydraulic OEM yari ikeneye ibice bifite GD&T guhamagara nka ⌀0.02 mm kwihanganira imyanya kuri 8 × M12 abayobozi bahujwe—Nta mashini ya kabiri. Ibyo birashoboka gusa mugihe cyo gushushanya, guhitamo alloy, hamwe na injeniyeri yububiko iba mumatsinda imwe ya tekiniki.
Twashyigikiye ibishushanyo 27 byo guteranya pompe aho abakiriya basimbuye imashini ikora ibyuma bidafite ingese hamwe nishoramari-bingana. Igisubizo? Kugereranya ibiro 38% ugereranije, 22% munsi yikiguzi cyose kuri buri gice, no gukuraho imashini 3-5. Ariko intsinzi ishingiye kubintu bibiri bidashobora kuganirwaho: gukurikiranwa kubintu kugeza ku mubare w'ubushyuhe, no kugenzura CMM mu byiciro bitatu - ntabwo ari ubugenzuzi bwa nyuma.
Aho Amasoko menshi ananirwa-nuburyo bwo kubyirinda
Abaguzi bamwe bibwira ko abashoramari bose bashoramari bakora cobalt-nikel alloys kimwe. Ntabwo babikora. AMS 5387 cobalt alloy isaba ubushyuhe bwuzuye bwumuriro mugihe cyo gutwika ibishishwa. Byihuta cyane? Microcracks. Biratinda cyane? Ibisigisigi bya karubone. Twabonye igipimo cya 41% kuri T800 ishingiye kuri shitingi ya shitingi mugihe ibishingwe byongeye gukoresha ibishishwa birenze 3-nta nteguza, nta raporo-yabitera.
Gukosora ntabwo ari amasezerano akomeye. Byashyizwemo uburyo bwo kugenzura: igihe nyacyo pyrometer yinjira mugihe cyo kwangiza, kugenzura umwuka wa ogisijeni igice cyisuka, hamwe no gupima ibice byihariye kuri buri bushyuhe. Ku kigo cyacu cya Qingdao, buri tombora ya AMS 5387 ikorerwa metallography mbere yo kurekurwa - ndetse no kuri prototypes. Ntabwo kuberako spes ibisaba, ariko kuberako cluster imwe yo gushiramo irashobora gutangiza kunanirwa umunaniro kuri 15,000 psi.
- Cobalt alloy nozzles: Imashini ivuye mubushoramari-busa hamwe na .080.08 Ra hejuru yo kurangiza mbere-kurangiza
- Imyanda: Shira muri ASTM A494 CW6MC, wapimwe kugeza 1.5 pressure umuvuduko wakazi hamwe na helium yamenetse
- Winch center shaft: Gushyushya ubushyuhe kuri HRC 52–56, ubukana bwashushanyijeho zone 12 ya radiyo
Ibi ntabwo ari ibintu bya catalog. Nibisubizo byahimbwe no gusesengura kunanirwa-ntabwo ari ibisobanuro byubushobozi.
Kwishyira hamwe bihagaritse mubyukuri bitanga umutekano
Outsourcing casting, gutunganya, no kurangiza kubacuruzi batandukanye bigwiza ibyago. Gutinda gukiza gukurura gusunika gahunda ya CNC. Ubuso bwubuso bwabonetse nyuma yo gusya imbaraga zisubiramo - cyangwa gusiba. Dukoresha uko ari batatu mu kigo kimwe cyujuje ISO: gutera ingirabuzimafatizo zegeranye n’ibigo bitunganya 5-axis, hamwe na laboratoire ya metrology hamwe no gukurikirana ibikoresho bihuriweho.
Ibi ntabwo bijyanye no korohereza. Nibijyanye no kugenzura ibihinduka caskade: guta kugabanuka bigira ingaruka kumurongo wanyuma; imashini iterwa no guhangayika ihindura nyuma yubushyuhe-bwo kugoreka; ndetse na pH ikonje mugihe cyo gusya impinduka imyirondoro isigaye mumazu yoroheje. Iyo itsinda rimwe rifite urunigi rwose, umuhamagaro wa GD&T ukomeza kuba mwiza kuva mubishashara kugeza kubisanduku.
Kurugero: umukiriya wu Burayi yari akeneye ibice 120 byumushinga wa pompe wicyuma ufite uburebure bwa mm0.1 mm hejuru ya mm 650. Abanywanyi bavuze ibyumweru 14. Twatanze muri 9-kubera ko abajenjeri bacu ba casting bahinduye igishushanyo mbonera gishingiye kumashusho nyayo yumuriro, kandi abakanishi bacu bakoresheje imashini imwe ya CMM kugirango yemeze ingingo ya mbere no kugenzura bwa nyuma. Nta ntoki. Nta gusobanura.
Guhitamo Igishoro cyawe Gufatanya Mubushinwa-Ibyo Kugenzura Ubu
Ntukabaze “Ukora ishoramari?” Baza aho:
- “Nyereka ubufindo bwawe bwa nyuma bwa AMS 5387 - burimo raporo zerekana amashusho, imirongo igerageza, hamwe n'ibiti byerekana ibizunguruka.”
- "Nigute ushobora kugenzura ituze rinini hagati ya casting na reta ya nyuma yakozwe? Ukoresha inzira zishyurwa ningutu?"
- "Ni ubuhe buryo ntarengwa bwo gutandukanya urukuta ku gice cya mm 30? Kandi wabipima ute - igishishwa cyinjira, mbere yo gusuka, cyangwa nyuma yo kurangiza?"
Ibisubizo nyabyo byerekana inzira ikuze. Ibyiringiro bidasobanutse ntabwo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikorera aho ibisobanuro bihuye no kubazwa: guta geometrike igoye muri superalloys, kwihanganira cyane utabanje gukora cyane, no gutanga ubunyangamugayo bukora - ntabwo ari ibice gusa. Iyo ushakisha gushora imari mu Bushinwa, reba ingano yinganda zashize hamwe nimpamyabumenyi. Shakisha ibimenyetso byerekana kunanirwa kugenzurwa - nuburyo byagize uruhare rukurikira.
