Iyo abajenjeri bagaragaje silika sol precision casting kubice byibyuma byukuri, ntabwo bahitamo inzira-bahitamo kwizerwa. Silica sol ishoramari itanga ± 0,05 mm kwihanganira ibipimo, ubuso burangirira kuri Ra 1,6 mm, hamwe nubusugire bwa net-nete kubice bikora munsi yumuvuduko wa hydraulic 350 cyangwa 600 ° C. Urwo rwego rwo guhuzagurika ntiruturuka kubishingwe rusange. Irasaba disipuline yibintu, metrology rigor, hamwe nuburambe bwimbitse bwihariye-cyane cyane amanota ya cobalt-nikel nka AMS 5387 na T800.
Kuki silika sol - atari ikirahuri cyamazi cyangwa fosifate - itsindira ubutumwa bukomeye bwa geometrie
Silica sol itanga ibyiza bitatu bidashobora kuganirwaho kurenza ubundi buryo bwo guhuza: ubushyuhe bwumuriro hejuru ya 1,100 ° C, ibisigara bya zeru alkaline nyuma yo kumera, hamwe nimbaraga zidasanzwe zidasanzwe mugihe cyo gusuka ibyuma byo hejuru. Twabonye amazi-ibirahuri byacitse mugihe cyo gutunganya ubushyuhe nyuma yubushyuhe mugihe igipimo cyo gukonja cyarenze 1.2 ° C / sek. Ibishishwa bya silika sol bifata ubudahemuka buringaniye muri ziriya nziga - birakomeye mugihe utunganya inzu ya pisitori ya pisitori ya pisitori aho itandukaniro ryuburebure bwurukuta rigomba kuguma munsi ya mm 0,12 kuri mm 320. Ububiko buke bwa binder nabwo butuma kwigana 0.3 mm z'ubugari bwa coolant grooves muri cobalt alloy nozzles-ibintu bidashoboka kongeramo post-cast bitabangamiye ubuzima bwumunaniro.
Guhuza Vertical ntabwo ari ijambo ryijambo-niyo nzira yonyine yo kugenzura uburinganire bwa microstructure
Abatanga ibicuruzwa benshi batanga casting, gutunganya, cyangwa kurangiza. Ibyo bitera icyuho cyamaboko: amafaranga 0,08 mm yimigabane kumashanyarazi ahinduka mm 0,15 nyuma yo gutunganywa nabi kubera kwambara ibikoresho bitanditse; kuvura ubushyuhe bigoreka ibipimo kuko ukora itanura abura igishushanyo cyambere cya GD&T. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibyiciro byose bibaho munsi yinzu imwe ya ISO. Iyo dutereye igice cya pompe ya AMS 5387, metallurgiste yacu igenzura ibikoresho fatizo mbere yo gushonga. Imashini yikipe yacu ya CNC iturutse muri as-cast ikoresheje imiyoboro ya CMM yatanzwe-nta kongera guhuza. Gusya hejuru birahita bikurikira nyuma yo kugabanya ibibazo, gufunga muburinganire muri mm 0.005 kuri mm 450 z'uburebure. Uku gukomeza kurandura ikosa ryuzuye - kandi risobanura impamvu 92% byinteko zumuvuduko winteko zitsinda ibizamini bikora kumurongo wambere.
Imikorere nyayo-isi itangirana na alloy-yihariye yo kwemeza
Cobalt-nikel alloys ntabwo yitwara nka 316 idafite umwanda. Igipimo cyo gukomera kwakazi kiyongera nyuma yo gukuraho 15%. Ubushyuhe bwumuriro buri munsi ya 30% ugereranije nicyuma cya karubone-bityo rero kugabanya amazi bigomba gukubita ibikoresho-inzira ihuza cyangwa gushonga kwaho bibaho. Dushushanya buri kintu cyose cya T800 mubitabo byibitabo byacu: kuzunguruka RPM, kugaburira ibiryo kuri buri gice, ndetse no gukonjesha nozzle. Kubikoresho bya cobalt alloy ifite uburebure bwa mm 0,8 mm, dukoresha 0.3 mm ya karbide ya ruganda kuri 18.000 RPM na 80 mm / min ibiryo - ibipimo byemejwe hejuru yikigereranyo cya 127. Abakiriya batuzanira ibishushanyo by'umurage bakunze kubaza bati: “Urashobora gufata mm 0.03 mm hano?” Igisubizo cyacu ntabwo ari theoretical. Ishingiye ku makuru yapimwe avuye muri geometrike imwe mu bicuruzwa byacu - nka winch center shaft roller batch aho raporo ya CMM yerekanaga 0,022 mm gutandukana cyane mubice 1200.
Guhitamo silika sol precision casting bisobanura kubaza ibibazo bitatu
- Bafite uburyo bwo kuvura ubushyuhe no kurangiza? Ibikorwa byoherejwe hanze bisiba gukurikirana. Niba pompe yawe idashoboye kwipimisha kunyeganyega, uwaguhaye isoko arashobora kwerekana neza ko ubushyuhe bwakoreshejwe - hanyuma ukabihuza nubushuhe bwambere?
- Bakora imashini zikomeye muburyo bumwe? Kongera gushiraho uburyo bwo guhuza drift. Shakisha ibikoresho bifite selile-axis ya CNC ikora byombi bikarangira bitarangiye nta gukuraho igice.
- Baratangaza amakuru yukuri yo kugenzura - ntabwo ari "ISO yemewe" gusa? Baza icyitegererezo cya CMM cyerekana gutandukana kwukuri guhamagarwa kwa GD&T. Nukuri silika sol precision casting uruganda kugabana ibyo-ntabwo bihishe inyuma yicyemezo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ibisubizo yego kuri bose uko ari batatu. Igikorwa cyacyo gikomatanyirijwe hamwe, amakarita yihariye yimikorere, hamwe nibisobanuro byuzuye bituma iba umufatanyabikorwa wongeye kubya hydraulic OEMs yo muri Amerika ya ruguru hamwe n’abakora ibikoresho by’ibikomoka kuri peteroli. Igisubizo? Ibice bihura neza - atari ku mpapuro gusa, ariko muri serivisi. Mugihe gukina-gutunganya imashini ivanze bigenda byiyongera, ikinyuranyo hagati ya "castable" na "precision-cast" kiraguka. Gusa uhagaritse, metrology-yashyizwemo ibikorwa birahuza.
