Ibice byibyuma bikora cyane ntibihanganira kumvikana-cyane cyane muri sisitemu ya hydraulic, peteroli na gaze, cyangwa imashini yimashini ya winch. Iyo ituze rinini, uburinganire bwa microstructure, hamwe no kwihanganira kwambara bigomba kuba munsi yumuvuduko wumurongo wa 300+ cyangwa 600 ° C mugihe kimwe, imashini gakondo cyangwa guta byonyine bigwa bugufi. Aho niho ubuhanga bwuruganda rwa powder metallurgie ruva muburyo bukenewe - ntabwo ari inzira yihariye, ahubwo nkibishobora gufata ingamba murwego rwo guhuza urusobe rwibinyabuzima.
Kuki Powder Metallurgie Yonyine Atari Igisubizo (Kandi Niki)
Ba injeniyeri benshi bibwira ko "powder metallurgie" bisobanura ibice byacumuye neza uhereye kubinyamakuru. Mubimenyerezo, bidakunze gutanga ubuso burangiye, imbaraga zingutu, cyangwa ubuzima bwumunaniro ukenewe kumazu ya pompe ya pompe cyangwa AMS 5387 cobalt alloy nozzles. Twabonye uburyo butatu bwo kunanirwa gusubiramo: guterwa no guterwa no gutemba mumibiri ya valve, imiterere yingano idahuye mumashanyarazi ya T800 ivangwa nubushyuhe, hamwe no gutandukana kwa GD&T nyuma yo gutunganywa kabiri kubera kugabanuka kwicyatsi kibisi.
Igisubizo nyacyo ntabwo ari uguhitamo * hagati ya * powder metallurgie nuburyo busanzwe-ni ugukurikirana mubwenge. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata ifu ya metallurgie ntabwo ari iherezo, ahubwo ni intambwe iboneye. Igice cya cobalt-nikel gitangira nkurushundura-rusa-rwashushanyije ubusa-hanyuma rukimukira muri 5-axis ya CNC ikora hamwe ninzira nyabagendwa yatunganijwe neza kuri gradients zisigaye. Nta kongera gushiraho. Nta guhungabana k'ubushyuhe biturutse ku buryo butandukanye bwo kuvura ubushyuhe. Gusa akazi gahoraho kuva kumashanyarazi kugera hejuru yimikorere.
Ubushobozi bune buhindura ifu Metallurgie mubikorwa byateganijwe
Ibi ntabwo ari theoretical. Yubatswe mubikoresho byacu byubahiriza ISO muri Qingdao-kandi byerekanwe muri sisitemu ya hydraulic 127 yongeye kugaragara mumyaka itanu ishize. Dore icyatuma ikora:
- Guhuza Ibikoresho-Gutunganya Guhuza: Dufatanya guteza imbere ifu yihariye hamwe nababemerewe gutanga ibicuruzwa - ntabwo ari kubigize imiti gusa, ahubwo no gukwirakwiza ingano (D50 = 15-18 µm) no gutembera (≤25 s / 50g Hall Flow). Kubera iki? Kuberako itandukaniro rya 3% mubucucike bugaragara rihindura kugabanuka kwa 0,012 mm-bihagije kugirango urengere ± 0.025 mm kwihanganira imyanya kuri pompe ya piston.
- Imashini-Yerekana Icapa: Itanura ryacu ryitanura ntabwo ryashyizweho kugirango rikomere cyane. Bakurikiranwe kumashini: gufata kuri 1180 ° C muminota 90 munsi ya argon, hanyuma ukagenzura gukonjesha kugirango ugumane ibice 25-35 bya HRC-byoroshye bihagije kugirango ibikoresho bya karbide bigabanye neza, bigoye bihagije kugirango birwanye galling mugihe cyanyuma.
- GD & T-Kumenya Ibikorwa Byakabiri: Igice cyose cyacumuye kibona CMM-scanne * mbere * gutunganya - ntabwo nyuma. Dushushanya ikarita nyayo ya geometrie irwanya CAD nominal, hanyuma tugatanga ibikoresho byifashishwa muburyo bwo guhuza n'imihindagurikire y'ikirere bigabanuka. Igisubizo: 94% umusaruro wambere-utanga umusaruro kubintu bigoye nkibizunguruka bitazengurutse ikigo cya shaft.
- Gukurikirana Hasi Kuri Batch Urwego: Buri tombora itwara inyandiko zuzuye - ntabwo ari ibikoresho byerekana gusa, ahubwo ni ibicu byangiza ikirere, raporo yo kugenzura ubucucike, hamwe nubushakashatsi bwakozwe nyuma yimashini (Ra ≤ 0.4 µm) byapimwe hakoreshejwe optique ya profilometrie. Nta bitekerezo. Nta ntoki zidafite amakuru.
Aho Powder Metallurgy Uruganda Ibisubizo Mubyukuri Gutanga ROI
ROI ntabwo yerekeye ibice bihendutse. Nijyanye no gukuraho uburyo bwo gutsindwa butwara amafaranga menshi. Tekereza AMS 5387 cobalt alloy ibice 6 bya pompe: guta ishoramari gakondo bisaba ibikorwa 7 (igishushanyo cyibishashara → igikonoshwa kubaka → gutwika → gusuka → HIP machine imashini itoroshye → imashini irangiza). Inzira yacu ya Hybrid irayigabanya kuri 4 (kanda → sinter → adaptive CNC pass pass yanyuma). Igihe cyo kuyobora kigabanuka kuva ku byumweru 14 kugeza kuri 6. Igipimo cyo gukuraho kigabanuka kiva kuri 18% kigera kuri 3.2%. Kandi ibipimo bikomeye CpK iguma hejuru ya 1.67-kuko kugabanuka ntabwo ari ibintu bisanzwe; ni icyitegererezo, gupimwa, no kwishyurwa.
Ariko intsinzi nini ni ubwisanzure. Umukiriya umwe wu Burayi yari akeneye umubiri wumuvuduko wumuyoboro ufite imiyoboro ikonjesha imbere ihuza 37 ° - ntibishoboka no gukurura intoki mu guta umucanga, birahenze cyane hamwe no gucukura EDM mububiko. Powder metallurgie reka dushyiremo ibitambo bya polymer cores * mugihe cyo gukanda *, hanyuma tubitwike mbere yo gucumura. Imashini yasukuye gusa umuyoboro winjira. Igihe cyose cyiterambere: iminsi 11. Prototype yambere ikora yatsinze igeragezwa kuri 412 bar.
Guhitamo Ifu Yawe Metallurgie Yumufatanyabikorwa: Amasheki atatu Ataganira
Inganda zose za powder metallurgie ntabwo zikora kururu rwego. Mbere yo kohereza ibishushanyo, baza ibibazo:
- Waba ukora progaramu yubucucike * kuri buri kintu * - ntabwo ari kuri shift imwe gusa? (Niba bavuga "yego" ariko ntibashobora kukwereka imiterere y'ibiti, genda.)
- Ese porogaramu zawe za CNC zishobora gutumiza dosiye yawe YINTAMBWE * hanyuma * igashyira raporo ya CMM igice cyacumuye kugirango itange ibikoresho byindishyi? (Niba software yabo ya CAM ifata ibicumuro byacumuye nkibikomeye, tegereza gukora.)
- Mugihe dusobanuye AMS 5387 cyangwa T800, ukura ifu yumutanga umwe wujuje ibyangombwa - hanyuma ugasangira raporo yikizamini cyurusyo * mbere yo gukanda? .
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ihura uko ari itatu-kandi itangaza uburyo bwo gucumura idirishya ryemeza amakuru mugice cya tekinike ya tsingtaocnc.com. Ntabwo ari kopi yo kwamamaza. Nka PDF zishobora gukururwa kugirango zisubirwemo.
Ibyuma bikora neza cyane bigenda neza mugihe ibikoresho siyanse, gutunganya neza, hamwe na disipuline nziza ihagarika gukora muri silos. Ifu ya metallurgie yinganda ikanda gusa na sinters itanga ibice. Imwe ihuza imyitwarire yifu muri buri gikorwa cyo hasi - kwemeza igishushanyo, igishushanyo mbonera, ibikoresho byabigenewe, igenamigambi - bitanga icyizere. Ngiyo inzitizi tunyuramo buri munsi muri Qingdao. Ntabwo ari amasezerano. Hamwe namakuru akurikiranwa, inzira zisubirwamo, nibice bifata igitutu mugihe ntakindi gishobora.
