Iyo abajenjeri bagaragaje ibyuma byihanganira cyane ibyuma bya pompe hydraulic, valve ya peteroli, cyangwa sisitemu yo gutwara ibinyabiziga, ntibakenera "casting." Bakeneye gutekana kurwego munsi ya 200 MPa. Microstructure ubunyangamugayo nyuma yo kuvura ubushyuhe. Kurangiza isura irwanya kwambara nabi. Kandi gukurikiranwa byuzuye - kumanuka gushonga hamwe na raporo yikizamini. Niyo mpamvu amakipe ashushanya muri Amerika ya ruguru no mu Budage ahora asubira kuri a uruganda rukora neza gushinga imizi ntabwo ari mubunini, ahubwo mubyiciro bya metallurgjiya: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Impamvu Cobalt Alloys isaba ibirenze gushinga
Ibishingwe byinshi bitera ibyuma cyangwa ibyuma bya karubone. Hafi ya AMS 5387 cobalt alloy - kereka niba ufite amabwiriza yo gusubiramo kuri T800 ishingiye kuri nozzles ikorera kuri 650 ° C mubidukikije. Twabonye abakiriya bahindura abatanga ibicuruzwa nyuma yicyiciro cya gatatu cyananiranye cyamazu ya pompe ya cobalt-nikel: kurwanira mugihe cyo kugabanya imihangayiko, guhagarika umutima hafi yinzitiro zoroheje, guhamagarwa kwa GD&T kubura na ± 0.03 mm hejuru yikimenyetso gikomeye. Intandaro? Ikinyuranyo hagati yubushobozi bwo gukina no kugenzura imashini nyuma yo gukina. QINGDAO QIANGSENYUAN aziba icyuho. Ikigo cyacyo gihuza ishoramari, guta umucanga, gutunganya imirongo myinshi ya CNC, hamwe no kuvura ubushyuhe bwa vacuum - byose munsi yinzu imwe yemewe na ISO. Nta ntoki. Nta bikoresho byongeye kumenyekana. Nta gutandukanya ibipimo hagati ya geometrie na datum ya nyuma yakozwe.
Kwishyira hamwe guhagaritse gushimangira ubworoherane - Ntabwo ari igihe gusa
Tekereza inzu ya piston ya pompe. Iratangira nkumucanga ushyizwemo ibyuma bidafite ibyuma hamwe na 1.5 mm yo gutunganya. Noneho ahura ningutu-yoroheje, gusya bikabije, kuvura ubushyuhe (igisubizo anneal + gusaza), kurambirwa neza kwimyanya itatu ya coaxial, hamwe no gusya hejuru kuri Ra 0.4 µm. Buri ntambwe ihindura imihangayiko isigaye na microstructure. Niba gutara no gutunganya bibera ahantu hatandukanye, amateka yubushyuhe arazimira. Kuri QINGDAO QIANGSENYUAN, itsinda rimwe riyobora urunigi rwose - uhereye ku cyemezo cy’ibikoresho fatizo (ubushyuhe bwose bushobora gukurikiranwa na raporo y'ibizamini by'urusyo) kugeza kuri CMM ukoresheje sisitemu ya Zeiss CONTURA G2 ihagarikwa buri munsi. Twapimye gusubiramo 0,012 mm kwihanganira imyanya hejuru ya mm 120 z'uburebure - ku bice aho inganda zemerera ± 0.05 mm. Ukwo guhuzagurika guturuka muguhindura ibihinduka abandi bafata nkibisanzwe: igipimo cyo gukonjesha, kuzimya ubushyuhe buciriritse, gutandukana mugihe cya 5-axis.
Aho "Ubworoherane Bwinshi" Buhura Nukuri-Isi Imikorere
Kwihanganirana cyane ntabwo ari micron gusa ku gishushanyo. Byerekeranye no kwizerwa kumikorere. Amacomeka ya cobalt agomba gufunga kashe ya 350 itandukanijwe mugihe irwanya galling mugihe cyo gukora inshuro nyinshi. Uruziga rwagati rwagati rugomba gukomeza kuzenguruka muri mm 0.008 hejuru ya 10,000 yikurikiranya. Ibi ntabwo aribisobanuro bya laboratoire - ni uburyo bwo gutsindwa twanditse mubyagarutse. Imbaraga za QINGDAO QIANGSENYUAN ziri mu guhuza metrologiya n'imikorere: optique profilometrie yemeza ubusugire bwubutaka mbere yo gutwikira; ibizamini bya ultrasonic bigenzura uburinganire bwubutaka mubice-byuzuye; n'ibizamini bikora - nk'amazu yo gusiganwa ku magare kugeza kuri 1.5 pressure igitutu cy'akazi - bibaho mbere yo koherezwa. Inyandiko zerekana ubugenzuzi zirimo GD&T kwemeza kuri buri cyiciro, ntabwo ari cheque yanyuma. Nuburyo batanga ibice bitari bisanzwe aho "as-mashine" isura ihura na ASME B46.1 Ra 0.2 µm - nta gusya kabiri.
Gufatanya Kurenga Gahunda yo Kugura
Abashushanya akenshi barabaza bati: “Urashobora gukora iyi geometrie muri T800?” Ikibazo nyacyo ni iki: “Bigenda bite iyo imiterere y'ibinyampeke tugabanije ubugari bwa mm 1,2 hano?” QINGDAO QIANGSENYUAN asubiza byombi - mugihe cyo gusuzuma, ntabwo nyuma yo gukoresha ibikoresho. Abayobozi bashinzwe imishinga bareba urukuta-ubugari buringaniye namakuru yo kwerekana imiterere. Bashyira ahagaragara ibishushanyo mbonera bidahuye no gukuraho ceramic shell. Basaba ko radiyo ntoya ihindura igabanya igihe cyo gukora 22% bitabangamiye ubuzima bwumunaniro. Iyi ntabwo ari serivisi ngishwanama - ni co-injeniyeri ishingiye kumyaka 17 ya pompe, valve, nibikoresho bikoresha ibikoresho biremereye. Kuri prototype ikora, kuyobora umwanya ugereranije iminsi 28 uhereye gushushanya. Kubicuruzwa byaciriritse (50-500 pcs / mwaka), itangwa ryogutanga rigera kuri 98.4% - ikurikiranwa na gahunda ya ERP ihuriweho na gahunda yo kugenzura ibikorwa.
Urebye imbere, icyifuzo cyo gukora imvange - aho gukina bisobanura geometrie nini na CNC isobanura ubuso bukora - biziyongera gusa. Ibikoresho nka cobalt-nikel superalloys ntibizoroha kumashini. Ariko ubushobozi bwo kubigenzura, kuva chimie yashonga kugeza kontour yarangiye, bikomeza kuba ibyemezo. Mugihe igice cyawe gikurikira-cyihanganira icyuma kigomba gukora - ntabwo gikwiye - tangira na a uruganda rukora neza ifata metallurgie nkubuhanga, ntabwo ari ubuhanzi.
