Iyo injeniyeri n'abashinzwe gutanga amasoko bashakisha hejuru yicyuma cyo guteramo inganda uruganda, ntibakenera gake kubitanga rusange. Bakeneye abafatanyabikorwa bumva impamvu cobalt alloy nozzle yananiwe kuri 650 ° C, uburyo AMS 5387 ihana imbibi n’ingano bigira ingaruka ku buzima bw’umunaniro w’amazu, cyangwa impamvu guhamagarwa kwa GD&T ku nzu ya silinderi ya piston bidashobora "kugereranywa" mu guta - hanyuma bigakorerwa imashini. Nibyo byukuri bikora inyuma yinganda zikora cyane. Kandi aho niho itandukanyirizo nyaryo ritangirira-atari mu gatabo, ahubwo ni mu bitabo byerekana ibimenyetso, CMM ivuga kuva kuri # A7291, hamwe n'umutekinisiye uhindura igipimo cy’ibiryo hagati y’imashini hagati kuko amashanyarazi ya T800 ya T800 asoma munsi ya 3% ugereranije n’ibiteganijwe.
Kuki "Hejuru" Bisobanura Ikintu Cyihariye Molding Injection
"Hejuru" ntabwo yerekeranye numutwe cyangwa amashusho ya kare kare. Nibijyanye no gusubiramo munsi ya metallurgical stress. Umufatanyabikorwa wo mu rwego rwo hejuru wa MIM agomba gukoresha amavuta ya cobalt-nikel atabanje gukata mikorobe mugihe cyo kwishura, kugenzura kugabanuka kwa sinte kugeza kuri ± 0.08 mm kumubiri wa valve ya mm 120, no kwemeza gukwirakwiza ubucucike hamwe na mape ya ultrasonic mape-atari ihame rya Archimedes gusa. Abacuruzi benshi bahagarara kuri "dukora MIM." Ibyiza bitangira ubaza: Nubuhe buryo bwo gutsindwa igice cyawe kibona? Inzira yumutwaro irangirira he? Ni ubuhe buso bwo kurangiza busabwa * kuri interineti ikora *, ntabwo gushushanya?
Twabonye ibintu bitatu byongeye kugaruka mubisoko byisi yose: Icya mbere, icyuho cyibikoresho byerekana-urusyo rwabuze ibipimo byo kuvura ubushyuhe cyangwa ibirimo ogisijeni ya superalloys. Icya kabiri, ibipimo bigenda byuzuzanya mubice kubera guhuza imyirondoro idahuye. Icya gatatu, hejuru yubuso bwasomwe nabi nkuko byemewe kuko ubugenzuzi bugaragara bwasimbuye ibice SEM isesengura. Ibi ntabwo ari "ibibazo bifite ireme." Nibikorwa byo kunanirwa kugaragara. Inganda zibirinda zisangiye ikintu kimwe: guhuza vertical yo gutegura ifu, kubumba, kubuza, gucumura, na HIP - buri cyiciro kigaburira amakuru yigihe gikurikira.
Ubujyakuzimu bwa tekinike hejuru yubunini: Aho Ubwubatsi Bwuzuye butuye
Fata ibyuma byumuvuduko wa sisitemu ya hydraulic. Ijambo risanzwe risaba kwihanganira, urwego rwibintu, nubunini. Amaduka yibanze yibanze arasaba umuvuduko ukabije wumuvuduko, guhuza amazi (urugero, HFD-U synthique na fosifate ester), kandi niba hejuru yikimenyetso gifitanye isano na elastomers cyangwa ibyuma-byuma. Ibyo bihindura byose: ikirere cyacumuye (vacuum na hydrogen), kugenzura nyuma yubuso bwa HIP kugenzura, ndetse nubunini bwa grit bwakoreshejwe mukuzenguruka kwa nyuma.
- Cobalt alloy nozzles isaba gukura kwimbuto zagenzuwe - neza cyane, kandi kurwanya isuri bigabanuka; bikabije, kandi guturika kwamashanyarazi biratangira
- AMS 5387 ibice bya pompe bisaba gucumura munsi ya 1260 ° C kugirango ubungabunge icyiciro cya mbere
- T800 ishingiye kuri winch shaft izunguruka ikenera kwigana icyerekezo mbere yo gushushanya - porosi igomba guhuza neza, ntabwo byanze bikunze.
Ibi ntabwo ari theoretical. Twasuzumye ibice 47 byananiranye MIM yaturutse mu majyepfo yuburasirazuba bwa Aziya OEM mu mezi 18 ashize. 63% yakurikiranye inyuma ya powder itemewe. 22% kugirango uhindure umwirondoro utandukanijwe na "kwemerwa" imbaraga zicyatsi. 15% gusa ni bo bagize uruhare mu buryo butaziguye. Ikiruhuko? Mugenzi wawe wo murwego rwo hejuru agomba gutunga laboratoire iranga ifu-cyangwa yagenzuye, amasezerano yo kugera kuri imwe.
Niki Ukuri-Isi Yukuri Irasa
Gukurikirana byuzuye ntabwo ari agasanduku. Ni urunigi: ifu mbisi lot → binder formulation log → mold cavity ID → gucumura itanura rya zone ubushyuhe ubushyuhe rate Igipimo cyumuvuduko ukabije → CMM ya nyuma ya scan ya coorateur. Ku mbaraga zayo zikomeye, ihuza ibipimo byose byingenzi nisomwa rya thermocouple ryafashwe mugihe cyagatatu cyo gucumura. Iyo umukiriya ashyize ahagaragara 0,015-mm-yo kuzenguruka hejuru ya silinderi yubatswe, igisubizo ntigikwiye kuba "tuzagikora." Bikwiye kuba: “Cavity # B7 yerekanye 0.012-mm yo kwagura ubushyuhe bwa 1100 ° C-dore igiti cy'itanura hamwe nigikorwa cyo gukosora twashyize mubikorwa kuri Lot # A7302.”
Urwo rwego rwo kubazwa rusaba ISO-yujuje ibyangombwa byinjijwe mu kazi-bidashyizwe hejuru. Bisobanura abakora logi gutandukana * mbere * gukanda buto ya "tangira cycle", ntabwo nyuma. Bisobanura ifu yinjira ibona XRF isesengura * na * ingano yubunini ikwirakwizwa na laser diffaction - ntabwo igerageza gusa. Bivuze ko buri gice cyarangiye gitwara QR code ihuza impanga zuzuye zuzuye: impapuro zerekana ibintu, ibipimo ngenderwaho, raporo zubugenzuzi, ndetse nindangamuntu yabakoraga igenzura ryanyuma.
Guhitamo Mugenzi wawe: Ibipimo bifatika, Ntabwo ari amagambo
Mbere yo kohereza RFQ, baza ibibazo bitanu - hanyuma usabe ibisubizo byanditse:
- Urashobora gutanga itanura ryubushyuhe bwubushyuhe bwa raporo yo kwemeza kubice bitatu byanyuma bya cobalt?
- Ni ubuhe buryo ntarengwa bwemewe bwa ogisijeni ppm muri AMS 5387 ibice byatsi mbere yo gucumura-kandi ubipima ute?
- Twereke raporo ya GD&T yubahiriza kubintu bigoye cyane (urugero, ≥10: 1 uburebure-bwimbitse) byibuze byibuze bitanu byukuri byahamagaye
- Nigute ushobora kugenzura uburinganire buri hagati ya mm-150 ya pompe? (Ibisubizo byemewe: micro-CT, ikarita yerekana umuvuduko wa ultrasonic. Ntibyemewe: "ikizamini gisanzwe")
- Nigihe kingana iki uhereye kubitamenyekana kugeza kumuzi bitera gufunga ubusembwa bwubuso?
Niba igisubizo kirimo "dukurikiza amahame yinganda" cyangwa "itsinda ryacu ryiza rirakemura ibyo," komeza urebe. Uwiteka hejuru yicyuma cyo guteramo inganda uruganda ntusobanure inzira-barabigaragaza. Kohereza raporo zingana na buri prototype. Basangiye gucumura kumurongo hejuru yubufindo. Bakwemerera kugenzura ifu yabitswe yububiko.
Igihe kizaza ni icy'amaduka afata MIM nk'umuyoboro wa net-hafi-ariko nka sisitemu yo gukora ibyuma. Ibyo bitangirana no kumenya neza aho cobalt yawe iva, uko binder yawe ibora, nimpamvu umwirondoro wawe wicyaha usa nkintoki-ntabwo ari inyandikorugero.
