Iyo injeniyeri zikeneye ibice byicyuma bifata kwihanganira cyane, bikarwanya kwambara cyane, kandi bikarokoka umuvuduko ukabije wa hydraulic cyangwa peteroli na gaze ibidukikije -ntibatura "gufunga bihagije." Bashaka a mim powder metallurgie uruganda hamwe na disipuline yemejwe mugukoresha cobalt-nikel superalloys, ntabwo ari imwe ikora inzira. Ariko dore ibyo amakipe menshi ashakisha avumbura gusa nyuma yo gutinda cyangwa kunanirwa-ingingo ya mbere: MIM ntishobora guhinduranya no gushora imari-cyangwa gutunganya CNC. Nibidukikije byuzuye. Kandi itandukaniro nyaryo ntabwo ari ibikoresho hasi. Nuburyo siyanse yibintu bifatika, gusobanura GD&T, hamwe na metrology-murwego-hamwe.
Kuki "Uruganda rwa MIM Powder Metallurgie" Akenshi Ijambo Ryishakisha Ribeshya
Abaguzi benshi bandika "mim powder metallurgy uruganda" muri Google bategereje umusaruro wa MIM - hanyuma bakagenda urujijo. Kubera iki? Kuberako indashyikirwa MIM isaba ibirenze kugaburira no gutanura. Irasaba ibishushanyo byimbitse byerekana umwirondoro, bigenzurwa na kinetic ya geometrike igoye, hamwe nindishyi zanyuma za sinteri zemewe mumigabane myinshi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twabonye abakiriya bohereza ibishushanyo mbonera byateguwe na MIM-gusa dusanga AMS 5387 cobalt alloy nozzle yarwanije mm 0.08 kumuhogo nyuma yo gucumura. Gukosora ntibyari byihuse igihe cyinzira. Yasubiragamo ibyatsi byatsi kandi igahindura igipimo cya feri ya 1.2 ° C / min. Urwo rwego rwo kugenzura ntiruba mu gatabo. Ituye mumateka yubushyuhe bwamateka, icyiciro cyo murwego rwo gukurikiranwa, hamwe naba injeniyeri bakoze 17,000+ cycle sinter kuri T800 yo mu rwego rwo hejuru.
Aho MIM ikwiranye-Kandi aho idakwiriye-mubice byinganda-Byuzuye
MIM irabagirana iyo geometrie igoye ihuye nuburemere bwimikorere. Tekereza inzu ya piston pompe yububiko ifite imiyoboro yimbere yimbere, imibiri ya valve yumubiri hamwe nintebe zishyizwe hamwe, cyangwa imashini ya shitingi ya winch ikenera gukomera byombi> 62 HRC hamwe nuburemere bukomeye> 120 J. Ibi ntabwo ari imitako cyangwa ibice bya elegitoroniki byabaguzi. Nibintu byingenzi-ubutumwa aho gutandukana kwa 0,05 mm bitera gutsindwa kumurima. Ariko MIM ntabwo buri gihe ari igisubizo. Turakunze gutanga inama yo kubirwanya kubice bisaba ubukana burenze mm 40 zambukiranya-cyangwa abakenera imbaraga za isotropic tensile hejuru ya MPa 1,450 nta gukanda isostatike ya kabiri. Muri ibyo bihe, uburyo bwacu bwo kuvanga butanga ROI nziza: ishoramari ryerekana neza + kurangiza neza CNC. Nibyo guhuza vertical-ntabwo imvugo yo kwamamaza. Bivuze ko tugenzura imigendekere yintete mugihe cyo guterera, hanyuma tugafunga ibipimo byanyuma hamwe na eshanu zitunganijwe hifashishijwe ibikoresho bya Renishaw-byashizweho hamwe no kugenzura CMM.
Ibintu bine bitaganirwaho kubijyanye na MIM Yizewe (Bishyigikiwe numusaruro nyawo)
- Ibiryo byemewe + Batch-yihariye ya Sinter Umwirondoro: Dutanga ifu ya MIM gusa muri ISO 9001 yemejwe nabatanga raporo yuzuye ya PMI. Buri tombora ibona umurongo wa sinter-yemejwe na dilatometrie kandi igenzurwa hifashishijwe ikarita ya microhardness ikoresheje zone 12 yikizamini.
- Muri-Gutunganya amarembo yikigereranyo: Nta “bugenzuzi bwa nyuma gusa.” Dupima ibice byicyatsi mubyiciro 3 byingenzi: nyuma yo kubumba, nyuma yo kwangirika, na post-sinter mbere yo kuvura ubushyuhe. Gutandukana> 0,03 mm itera guhita imizi-isubiramo-ntabwo ikora.
- GD & T-Isubiramo ryambere ryubuhanga: Itsinda ryacu ryerekana ibishobora kugerwaho mbere yo gusubiramo - nkibicuruzwa bifata umutego, cyangwa inkuta zoroshye (<1,2 mm) ikunda kurwanira muri cobalt. Turasubiza ibishushanyo bisobanuwe hamwe nubundi buryo, ntabwo "bidashoboka."
- Inzira Yuzuye Hasi Kuri Ubushyuhe: Igice cyose cyoherejwe hamwe nicyemezo cyerekana ubushyuhe bwibikoresho fatizo, ID itanura ya sinter, guhinduranya ibikorwa, hamwe nindangamuntu ya raporo ya CMM. Nta na kimwe kidasanzwe - ndetse no kuri prototypes.
Ibizaza nyuma yingingo ya mbere - Nimpamvu bifite akamaro kanini
Inganda nyinshi zometse ku ngingo ya mbere. Bake babikomeza mubice 500. Ku kigo cyacu cya Qingdao, ituze ritangirana nibikoresho. Dufatanya gutezimbere ibyokurya hamwe nababitanga - cyane cyane kuri T800 ishingiye ku mavuta - tureba ko umwuka wa ogisijeni uguma munsi ya 180 ppm kandi gukwirakwiza ingano (D50) bifite ± 0.3 mkm kuri byinshi. Noneho haza disipuline yuburyo: buri sinter cycle yerekana ikirere cyikime, igipimo cya vacuum, nigihe cyo gutura mubushyuhe bwo hejuru. Niba ikintu kimwe kigenda hanze ya SOP, ubufindo bwose bukorerwa ibizamini bya ultrasonic 100% - ntabwo ari icyitegererezo. Niyo mpamvu gahunda yacu yo gusubiramo PPM yicaye kuri 147, ntabwo 1200. Niyo mpamvu kandi OEMs yuburayi hydraulic OEM idusobanurira inteko ya pompe ya fondasiyo isaba ≤0.02 mm iringaniye hejuru ya mm 320-idasya.
Urebye imbere, icyifuzo ntabwo ari "MIM nyinshi." Ni kuri ubuhanga bwo gukora Hybrid. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ni ukubaka ubwo bushobozi ubungubu-ntabwo ari imishinga ya R&D, ariko nkibikorwa-byiteguye gukora. Niba igice cyawe gikurikiraho-cyuzuye cyicyuma gikeneye ibipimo byukuri, ntabwo bitunganijwe gusa, tangira kumpapuro zifatika, ntabwo ari udutabo. Noneho ubaze: Bashobora kubigaragaza - byinshi kubufindo, igice kubice?
