Iyo ba injeniyeri bagaragaje ishoramari guta silicone sol uruganda ubushobozi, ntibashakisha gusa uwabitanze-barashaka ituze ryikigereranyo munsi yubushyuhe bwumuriro, guhuza microstructural guhuza ibiro 50 pompe ya cobalt alloy pompe, hamwe no kutihanganira zeru kumyuka mumibiri ya AMS 5387. Uku nukuri kubikorwa tubona burimunsi kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-uruganda rukorera muri Qingdao aho "silicone sol" itari ijambo ryijambo; ni sisitemu ya binder ifite 12-micron yubuso bwo kwihanganira kurangiza kuri T800 alloy nozzles mbere yo guta.
Twatanze ibice birenga 17,000 bya cobalt-nikel kuva muri 2019 - buri kimwe cyakurikiranye icyiciro, umubare wubushyuhe, na raporo yubugenzuzi bwa CMM. Mu mushinga umwe wo muri Amerika y'Amajyaruguru hydraulic OEM, inzu ya pisitori ya pisitori ya piston yananiwe inshuro eshatu hamwe na silika ihanganye na silika ihanganye: microcrack zakozwe mugihe cyo kwangirika kwamazi bitewe no kwagura ubushyuhe budahuye hagati yikibumbano ceramic na T800. Ifumbire ya silicone sol, yakize kuri 180 ° C aho kuba 120 ° C, yagabanije imihangayiko isigaye kuri 41% - byagenzuwe hakoreshejwe isesengura rya XRD. Ibyo ntabwo ari ibitekerezo. Niyo mpamvu abakiriya batwoherereza ibishushanyo bya GD & T-biremereye hamwe na ± 0.015 mm byukuri guhamagarwa-kandi bagategereza kwemezwa ningingo ya mbere.
Ibitandukanya ukuri ishoramari guta silicone sol uruganda uhereye kuri caster-rusange? Ibintu bitatu bidashobora kuganirwaho: Icya mbere, kugenzura ibikoresho fatizo. Dutanga gusa AMS 5387 cobalt alloy ingots hamwe na raporo yikizamini cyuzuye - ntabwo ari ibyemezo gusa. Icya kabiri, igikonoshwa cyemewe. Igice cyose cyigikonoshwa gipima imbaraga zishyushye kuri 1,150 ° C mbere yo gusuka. Icya gatatu, disipuline ya nyuma ya geometrie. Ibice bikozwe mu mucanga bigabanuka bitateganijwe; gushora imari ukoresheje silicone sol igabanuka muri ± 0,12% - ariko gusa iyo ugenzuye uburyo bwo kwagura ibishashara, ibishishwa byumye (≤35% RH), no kurasa ibiciro. Twandika uko ari batatu mugihe nyacyo.
- Ubuhanga bwibikoresho birenze impapuro zihariye: Ntabwo "dukora" T800 gusa-tuzi aho eutectic yo gushonga ihinduka 23 ° C mugihe chromium igabanutse 0.4%. Niyo mpamvu itanura ryacu thermocouples ihindurwa buri munsi kurwanya ibipimo bya NIST.
- Nta "agasanduku k'umukara" gutunganya: Ibyuma byose cyangwa ibyuma bidafite ingese bigenda neza biva muri shell biva muri CNC - nta kuvura ubushyuhe hagati keretse byateganijwe. Kubera iki? Kuberako murugo rwacu imashini 5-axis ifata ± 0.008 mm ihagaze neza kuri pompe ya pompe ya mm-300, ikuraho amakosa yo kongera guhuza.
- Gukurikirana bitangira mbere yo gusuka: Buri tombora itwara QR yanditseho tagi ihuza ibikoresho, igiceri cyubaka ibiti, gusuka umurongo wubushyuhe, hamwe na raporo ya nyuma ya CMM - byose bigera kubakiriya binyuze kumurongo wizewe.
Bamwe bashobora kuvuga ko silicone sol irenze ubuhanga bwo gukora hagati. Ariko tekereza kuri ibi: Umwubatsi wibikomoka kuri peteroli yo mu majyepfo yuburasirazuba bwa Aziya yari akeneye ibice 220 bya plaque idasanzwe ya cobalt. Abanywanyi bavuze umusenyi-hanyuma bongeraho $ 14,000 yo gukosora icyitegererezo nyuma yingingo ya mbere ibipimo. Twatanze ibyemezo byambere dukoresheje ibishishwa bya silicone sol, hamwe nuburinganire bwurukuta rwa mm 0,18 mm mubice 120 mm. Delta igiciro? 7.3% hejuru kuri buri gice - ariko 100% munsi yubuhanga bwo gukora, gusiba zeru, no gutanga iminsi 19 mbere yigihe giteganijwe. Gutora neza ntabwo ari ukwirinda gukora imashini-ni ukugenzura aho nuburyo bingana.
Reba ahazaza: Turimo kwagura ubushobozi bwa silicone sol kugirango dushyiremo Hybrid hafi-net-shusho ya casting + itomoye EDM kumiyoboro ikonjesha imbere mumibiri yumuvuduko mwinshi-imiterere idashoboka gucukura post-cast. Ariko ibyibanze byumunsi ntabwo bihinduka: gutanga ibyuma byumuvuduko bifunga kashe ya 420 nta kumeneka, amazu ya pompe arokoka ubuzima bwamasaha 15,000 mugihe cyogusebanya, hamwe na winch center shaft rollers hamwe na gradients zikomeye zagenzuwe na mape ya Vickers. Niba porogaramu yawe isaba ubunyangamugayo busubirwamo - ntabwo ari "guta icapiro" - hanyuma iburyo ishoramari guta silicone sol uruganda ntibisobanuwe na kare kare amashusho cyangwa ibisohoka buri mwaka. Byasobanuwe na diameter ntoya ya pore igice cyawe cyingenzi gishobora kwihanganira… na disipuline yuburyo bwo kubyemeza.
