Iyo ba injeniyeri bagaragaje Amavuta 6- cyane cyane AMS 5387 cyangwa T800 yo mu rwego rwa cobalt-nikel-ntabwo bahitamo ibicuruzwa. Barimo guhitamo uburyo bwo kurinda sisitemu aho gutsindwa bisobanura igihe cyo gutinda, ibyago byumutekano, cyangwa kumeneka gukabije. Niyo mpamvu gushakisha an Alloy 6 uruganda ntabwo bijyanye nigiciro kuri kilo. Byerekeranye no guhuza metallurgiki, gusubiramo ibipimo munsi yubushyuhe no guhangayika, no kwihanganira zeru gutandukana na microstructural.
Twabonye imishinga myinshi ihagaze - ntabwo ari ugusubiramo ibishushanyo, ahubwo ni ubugenzuzi bwingingo ya mbere. Inzu ya pompe iracika mugihe cya hydrotest. Nozzle irasimba nyuma yo kuvura ubushyuhe. Icyuma cya piston cyananiwe kugenzura hejuru-nubwo ibikoresho byemewe "byemewe". Muri buri kintu cyose, intandaro yaturutse ku cyuho kimwe: uruganda rwafataga Alloy 6 nkikindi kintu kivanze, ntabwo ari ubushyuhe bwo hejuru, ruswa-yangirika, super-ductility superalloy isaba indero yuburyo buri cyiciro. Aho niho inganda zuzuye zitandukanya kwizerwa ningaruka.
Ubushobozi bwa Alloy 6 ubushobozi butangira mbere yo gutunganya. Ibikoresho bibisi bigomba kuba byuzuye neza - ntabwo ari umubare wibyiciro gusa, ahubwo raporo yipimishije yuruganda rwahujwe na AMS 5387 imipaka yimiti: ≤0.15% C, 27-33% Cr, 4-6% Ni, 2–3% Mo, hiyongereyeho Fe, Si, Mn, nibintu bisigaye. Tugenzura buri giceri na ingot tumaze kwakirwa dukoresheje OES spectroscopy - ntabwo irwanya gusa amazina, ahubwo tunareba amadirishya yerekana amateka afitanye isano nimbaraga zikaze hamwe no kurwanya amarira ashyushye mubushoramari. Umukiriya umwe yatwoherereje fagitire ya T800 yanditseho "AMS 5387 yujuje." Laboratwari yacu yasanze karubone 0.21%. Igisubizo? Kugabanuka nku-guhindagurika. Twarabyanze - kandi twongeye gukoresha ubushyuhe bwo kuvura ubushyuhe hamwe na stock yagenzuwe. Ibyo ni ubugenzuzi budasubirwaho.
Igicuruzwa cyacu gikubiyemo ibintu bitatu bifatanyirijwe hamwe: gushora imari, gutunganya imirongo myinshi ya CNC, no kuvura ubushyuhe bwa vacuum - byose munsi yinzu imwe yemewe na ISO 9001. Kuki guhuza vertical bifite akamaro kuri Alloy 6? Kuberako cobalt-nikel alloys igabanuka bitateganijwe mugihe cyo gukomera no kugoreka mugihe cyo gukonja. Amaduka ya casting adakoresha imashini ibice byayo ntashobora guhuza neza amarembo cyangwa gushyira riser hashingiwe kumibare yo kugoreka nyuma yimashini. Mu buryo nk'ubwo, iduka rya CNC ridafite ubumenyi ntirishobora guteganya ihinduka ryibanze mu mazu akikijwe n'inkuta-cyangwa guhindura inzira y'ibikoresho kugirango wirinde microcrack ziterwa na mikorobe munsi yubutaka bukomeye. Dukoresha ibitekerezo bifunze-bisubizwa: CMM yogusuzuma ibice byarangiye igaburira muburyo bukurikira. Nta ntoki. Nta bitekerezo.
- Imyanda.
- Inzu ya pisitori ya pompe.
- Winch center shaft.
- Cobalt alloy nozzles hamwe namacomeka.
Bamwe bashobora kuvuga ko amasoko yo hanze yishingira igiciro gito - kugeza igihe azagira uruhare mubikorwa byo kongera gukora, gutwara ibicuruzwa byo mu kirere kubisimbuza byihutirwa, cyangwa amasaha yubwubatsi yakoresheje yujuje ibyangombwa bishya bitanga isoko hagati. Twashyigikiye hydraulic OEM yo muri Amerika ya ruguru binyuze mu gutangiza imyaka itatu ikurikiranye-buri kimwe gisaba kwanga-ingingo-ya mbere yo kwangwa hamwe nigihe cyo kuyobora gihamye munsi yibyumweru 12 kubitumiza hagati. Nigute? Mugushyiramo injeniyeri yumushinga hakiri kare: gusuzuma ibishushanyo mbonera, gushira ahabona amakimbirane ya GD&T mbere yuko ibikoresho bitangira, no gutanga ubundi buryo bwo kuvura ubushyuhe bugabanya igihe cyinzira bitabangamiye guhangana n’ibikurura. Gukorera mu mucyo ntabwo ari intero-ni buri munsi dusanganywe ikibaho gikurikirana ibintu fatizo, raporo ya CMM yerekana igihe, n'amatariki yo gukuraho NDT.
Urebye imbere, icyuho nyacyo muri Alloy 6 iminyururu itanga ntabwo ari ubushobozi-ni ubujyakuzimu bwa tekiniki. Amaduka menshi avuga ko ubushobozi bwa cobalt-alloy bushobora kurenza 0,01 mm kwihanganira imyanya kuri 300 mm flange mumaso nyuma yo kugabanya ibibazo. Bake baracyemeza ingano ya microstructure ingano yubunini bwigice cyangwa guhuza ubuso bukabije Ra agaciro hamwe nisuri-ruswa ikora mubidukikije bya gaze. Niyo mpamvu intego yacu ya R&D ikomeje kuba nto: guteza imbere ibikorwa bya Hybrid casting-gutunganya akazi kumateraniro ya pompe igoye, kwagura impamyabumenyi ya AMS 5737 na ASTM F75, no kubaka ibyuma byimpanga bigereranya kugoreka ubushyuhe kuri buri muryango mushya - mbere yuko ibishashara byambere bisukwa.
Niba gusaba kwawe kugusaba Amavuta 6 ikora - ntabwo yatsinze ubugenzuzi gusa - ukeneye ibirenze umucuruzi. Ukeneye umufatanyabikorwa wa tekiniki ufata garama zose za cobalt-nikel nkibikorwa remezo bikomeye. Ibyo bitangirana nuburyo ibikoresho byinjira mumuryango, bikomeza muri buri mpinduramatwara ya spindle hamwe no gutanura itanura, bikarangira gusa iyo sisitemu yawe ikora kumuvuduko ukabije kumasaha 10,000. Nibisanzwe inyuma ya buri Alloy 6 uruganda icyemezo dufata-nimpamvu abajenjeri bagaruka, igice nyuma y igice, umwaka nuwundi.
