Gukora ibishashara kubikorwa byabuze ibishashara byatakaye ntabwo ari imiterere-ni ubusobanuro bwambere bwumubiri bwibikorwa bifatika mubikorwa byakozwe. Muri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twashushanyijeho ibishashara birenga 12.000 kuva mu mwaka wa 2018 - buriwese agaburira mu ishoramari ry’imyuka ya hydraulic, amazu ya pompe ya cobalt-alloy, hamwe na shitingi ya shitingi ikora munsi ya 350 na 450 ° C. Ikitandukanya icyitegererezo gifatika nigiciro gihenze ntabwo ari ubudahemuka buringaniye gusa, ahubwo ni ubushyuhe bwumuriro, imyitwarire yo kurekura hejuru, hamwe no guhuza na ceramic shell sisitemu. Ibi twabyize inzira igoye: icyiciro kimwe cya AMS 5387 cobalt alloy nozzles yananiwe gufatira mugikonoshwa mugihe cya dewaxing - bitatewe nicyuma, ariko kubera ko ibishashara byumwimerere byagabanutseho 0.32% kurenza uko byagaragajwe mugihe cyo kwikora.
Kuki Gukora Ibishashara Byerekana Gutanga Umusaruro - Ntabwo ari Geometrie gusa
Inganda nyinshi zifata ibishashara bibajwe nkibikoresho byoroshye. Turabifata nkibikorwa bikora birahinduka. Mu ruganda rwacu rwa ISO rwujuje ibisabwa, ibishashara byose bigira intambwe eshatu zo kwemeza mbere yo kurekurwa: gushushanya ubushyuhe bwumuriro (bipimirwa kuri 25 ° C → 65 ° C → 100 ° C), igeragezwa ryikigereranyo cyikigereranyo cyerekana ibipimo bya zircon-silika bisanzwe, hamwe no gushushanya indishyi za CNC. Kubera iki? Kuberako gutandukana kwa mm 0,15 muri geometrie ihinduka 0,22 mm mubyuma byanyuma bidafite ingese nyuma yo kugabanuka, kuvura ubushyuhe, no gusya - kandi ibyo bikaba birenze guhamagarwa kwa GD&T kumazu ya pompe ya piston pompe kuri 37%. Twifashishije imiryango ibiri yibishashara: gushonga gake (58-62 ° C) kumuyoboro utoroshye wo gukonjesha imbere mumashanyarazi ya T800, hamwe na microcrystalline ivanze cyane (72-76 ° C) kumashanyarazi manini yimashini yimashini aho gukemura ibibazo birinda kugoreka mugihe cyo kwibiza.
Uburyo Bune Bwuzuye-Isi Yatsinzwe-nuburyo Twabikumira
Gukora ibishashara kubutaka bwibishashara byabuze uruganda rukora birananirana bucece kugeza igishishwa cyacitse cyangwa guta kugoreka. Ukurikije isesengura-mizi 217 muri Amerika y'Amajyaruguru na EU igaruka, dore icyacitse:
- Amashanyarazi ya hystereze: Ibishashara bishyushye nyuma yo gukomera igice biteza imbere microfractures. Dutegetse gushonga k'umuzenguruko umwe no kugenzura ubushyuhe bukabije - nta "rework realt" byemewe.
- Kugumana Ubuso: Amababi asigara ya stearic acide irinda no gutwikira. Ibishashara byacu birimo ≤0.8% bya aside irike yubusa; ibyiciro byinjira bigenzurwa hakoreshejwe FTIR spectroscopy.
- Ibikoresho bya CNC: Ibishashara byoroshye bigenda munsi ya 12,000 ya RPM irangira, bigatera amakosa yintambwe mubice byinshi. Twabanje gukonjesha kugeza kuri 18 ° C ± 1 ° C mbere yo kuyitunganya - yagenzuwe hamwe na thermocouples yashyizwemo.
- Kugereranya ibipimo mugihe cyo guterana: Kugurisha intoki ibishashara byaguka byihuse kuruta ibikoresho byababyeyi. Twahinduye kuri ultrasonic gusudira kumateraniro yose igizwe - kugabanya itandukaniro riva kuri mm 0.13 kugeza kuri 0.04 mm.
Ibi ntabwo ari impungenge. Binjiye mububiko bwacu budahuza hamwe namafoto, raporo za CMM, hamwe na metallurgical cross-section-iboneka kubakiriya babishoboye babisabwe.
Ukuntu Kwishyira hamwe bihindura ibishashara mubyuma byateganijwe
Abatanga ibicuruzwa benshi bagurisha ibishashara bibajwe. Bake kugenzura ibiba nyuma yo kuva muruganda rwa CNC. Kuri QINGDAO QIANGSENYUAN, ba injeniyeri bamwe bategura imashini zibaza ibishashara na bo bashiraho umurongo wo gutwika ibishishwa, bagenzura isuka ifashwa na vacuum, kandi bakemeza ubukana bwa nyuma ku kintu cyarangiye cobalt-nikel. Uku gukomeza gukuraho icyuho cyamaboko. Kurugero: mugihe umukiriya yasabye kuzenguruka cyane kuri pompe ya AMS 5387, twahinduye ubucucike bwibishashara (kuva kuri 0,91 g / cm³ kugeza kuri 0,93 g / cm³), duhindura umwirondoro wumuvuduko wamazi, kandi twongera igihe cyo gutura mbere yiminota 18 - byose mubikorwa bimwe. Igisubizo: kuzenguruka byateye imbere kuva kuri 0.082 mm kugeza kuri 0.031 mm udahinduye icyuma cyangwa kuvura ubushyuhe.
Ibi bikora gusa kuberako ikigo cyacu gikora casting, gutunganya-axis nyinshi, no kurangiza munsi yinzu. Nta muntu utanga ibishashara byo hanze ashobora guhindura imiterere yabyo kuri sisitemu yihariye ya shell, igipimo cyo gutanura itanura, cyangwa ingamba zo gusya nyuma. Ihinduramiterere riba mugihe nyacyo - hamwe namakuru.
Guhitamo ibishashara biba ni uguhitamo umufatanyabikorwa wawe
Niba urimo gushakisha ibishashara bikozwe mu gishashara cyatakaye mu ruganda rurimo amavuta ya cobalt, hydraulics yumuvuduko ukabije, cyangwa inteko zikomeye za pompe, baza ibibazo mbere yo gutanga itegeko:
- Bashobora gutanga imirongo igabanya ubushyuhe bwapimwe ku gice cyawe cya geometrie - ntabwo ari ibizamini rusange?
- Ese bemeza ibishashara-kuri-shusho yimbaraga ukoresheje ibihimbano byawe hamwe nibipimo?
- Ese gahunda yabo ya CNC itezimbere kubishashara byawe byihariye - cyangwa bashingira kumasomero rusange ya G-code?
- Bashobora gukurikirana buri gishashara cyibikoresho byacyo, amateka yubushyuhe, nigiti cyo gutunganya?
Turasubiza yego kuri bane. Ntabwo nkibisabwa byo kwamamaza - ahubwo byubatswe muri bariyeri muri sisitemu yubuziranenge ya AS9100. Ibicuruzwa byose bikozwe mu bishashara birimo icyemezo cya digitale hamwe na CMM scan hejuru, ibishushanyo mbonera byerekana ubushyuhe, hamwe nigisubizo cyibizamini bya shell. Kuberako mubikorwa byo gutunganya inganda neza, ibishashara ntabwo ari intangiriro. Nibintu byambere byo kugenzura.
Kubufatanye bwa tekiniki kubijyanye no gushushanya ibishashara byo gutakaza ibishashara byatakaye-cyane cyane kubutaka bwa cobalt-nikel, imibiri yumuvuduko mwinshi, cyangwa ibice bya pompe bidasanzwe - sura https://www.tsingtaocnc.com. Dushyigikiye gushushanya kwemeza, gusobanura GD&T, no gutanga ibitekerezo-mbere yuko ibishashara byambere biremerwa.
