Uruganda rukora amashanyarazi rukora neza ntirutangirana nibikoresho byihariye - bitangirana nigice * kitazagabanya *, * kitazakomeza kwihanganira *, cyangwa * kitazabaho muri serivisi *. Twabibonye inshuro nyinshi: amazu ya pompe ya cobalt-nikel yamenetse munsi yumuvuduko wa 300-bar; AMS 5387 nozzles yananiwe gusubiramo ibipimo nyuma yo kuvura ubushyuhe; T800 alloy center shaft umuzingo wambaye kimwe mumasaha 200 yo gukora. Ibi ntabwo ari ugukora inenge. Nibikoresho-bidahuye-kandi bitwara igihe, gusiba, no kwizerwa.
Iyo Imashini isanzwe igeze aho igarukira, Intambwe ya Electrochemic Machine Intambwe Muri
Gutunganya amashanyarazi (ECM) ntabwo ari "CNC nziza." Nuburyo butandukanye bushingiye kubikorwa bya fiziki-kudahuza, nta kwambara ibikoresho, guhangayikishwa na zero. Ibyo bifite akamaro kanini mugihe ukuyemo ibintu muri superalloys ikomye nka cobalt-chrome cyangwa nikel ishingiye kuri nikel ya Inconel aho gusya gakondo bitera micro-crack, burrs, cyangwa guhangayika bikabije hejuru. Ku kigo cyacu cyujuje ISO muri Qingdao, dukoresha ECM ntabwo nkigikorwa cyihariye - ahubwo nkigisubizo cyerekanwe, gishyizwe hamwe muburyo bwuzuye bwibyuma bikora. Turayikoresha kugirango turangize ibintu byingenzi byimbere mumazu ya piston pompe ya pisitori aho urusyo rwanyuma rudashobora kugera, kugirango dusubize intebe yumuvuduko mwinshi wa valve udahinduye guhamagarwa kwa GD&T, no kugera kuri ± 0.01 mm uburebure bwurukuta rwa 360 ° ya rotine ya winch center shaft roller - ikintu gisya urugamba rwo kwigana murwego rwo hejuru.
Ariko dore ibyo abaguzi benshi birengagiza: Intsinzi ya ECM iterwa cyane na mashini nibindi byinshi kubintu bitatu bifatanyirijwe hamwe - gukora electrolyte, gushushanya cathode kwizerwa, no kugenzura igihe nyacyo. Cathode idahwitse itera taper; electrolyte itabujijwe itwara pH ikanangiza ubuso burangije; umuvuduko udatemba utemba utera umwobo waho. Twemeza buri giciro kirwanya ibice byabakiriya-ntabwo ari ibizamini byo kugerageza. Kurugero, mugihe OEM hydraulic OEM yari ikeneye gusubiramo 0,05 mm z'ubugari bwa plaque ya AMS 5387, twakoresheje ibigeragezo 12 byerekanwa hamwe na optique profilometrie hamwe na metallografiya yambukiranya ibice - ntabwo ari CMM gusa - kugirango dufunge ubushyuhe bwa electrolyte, umuvuduko wa voltage, hamwe n’ikinyuranyo hagati ya electrode mbere yo gukora umusaruro wa mbere.
Impamvu Kwishyira hamwe Bikubita "ECM-Gusa" Amaduka kubutumwa-Ibice by'ingenzi
Abacuruzi bamwe bagurisha ECM nka serivisi. Twabishyize imbere muri casting-to-kurangiza akazi-kuko kunanirwa kwa ECM gukomeye bibaho * mbere yuko * igice gikora ku bwogero bwa electrolyte. Microstructure ikennye? Ubwoba hafi yikimenyetso gikomeye? Icyerekezo cy'intete kidahuye muri T800 alloy? Izo nenge ziyongera mugihe cya ECM, ntabwo zihishe. Niyo mpamvu uruganda rwacu rutunganya amashanyarazi rukora rukorera munsi yinzu imwe hamwe no gushora imari, imirongo myinshi ya CNC, hamwe no kuvura ubushyuhe bwemewe. Turagenzura urunigi rwose: ibikoresho fatizo bikurikiranwa (ibivangwa byose bya cobalt-nikel biva mu ruganda rukora urusyo), mbere yo gutunganya ibizunguruka, hamwe na pasiporo ya ECM nyuma ya ECM cyangwa amashanyarazi bigamije kurwanya ruswa - ntabwo ari ubwiza gusa.
Dufata kandi GD&T ntabwo ari impapuro-ahubwo ni ikarita yo kugabanya imashini. Mugihe dusubiramo ibishushanyo byumuvuduko wibitutu, dushyira ibendera aho kwihanganira umwirondoro (urugero, 0,02 mm UZ) bivuguruzanya nibisobanuro bya ECM bigerwaho. Aho kwanga icapiro, turasaba uburyo bwimvange: imashini itoroshye hamwe na CNC, hanyuma ECM mm 0.15 yanyuma kugirango ikubite imiterere nubusugire bwubuso. Ibyo bigabanya igihe cyizunguruka 37% na ECM yose mugihe wujuje ASME B16.34.
Kwemeza-Isi Yukuri: Niki Cyakora (nibitagenda)
Abakiriya bacu babaza ibibazo bitatu mbere yo kwiyemeza ECM:
- “Urashobora gufata mm 0.005 mm kuri 200 mm ya diametre y'imbere?” Yego - niba igice cya geometrie cyemerera electrolyte imwe kandi cathode ikaba ikomeye. Turabikora burimunsi kuri pompe ya pompe ya peteroli yo hanze na gaze.
- Ati: "Ni ubuhe bunini ntarengwa bwerekana neza?" 0,12 mm ahantu muri cobalt alloy nozzles, yagenzuwe na metero ya SEM - ntabwo ari optique.
- Ati: "Waba ushyigikiye amavuta adasanzwe nka T800?" Yego. Ariko dukeneye ibinyabuzima byuzuye hamwe namateka yo kuvura ubushyuhe. Bitabaye ibyo, ibya chimiya ya electrolyte ihinduka gukeka-kandi ibipimo byazamutse.
Twanze 11% ya RFQs yambere - ntabwo biterwa nubushobozi buke, ariko kuberako igice cya geometrie cyangwa ibintu bifatika bituma ECM idatanga umusaruro. Ibyiza kuvuga "oya" hakiri kare kuruta gutanga igice cyatsinze igenzura ariko bikananirana mugupima umurima.
Kureba imbere: Icyitonderwa ntabwo gihamye-Ntabwo ari inzira zacu
Ubushobozi bwukuri bwamashanyarazi yimashini isobanura guhindagurika birenze uburinganire bwimikorere ihuza imikorere. Kuri ubu, turimo kwuzuza ibipimo bya pulsed-ECM kugirango tunonosore ubukana bwumurongo kuri turbine blade yumwirondoro-no guhuza ibyuma bifata ibyuma byifashishwa kugirango uhindure moteri ya electrolyte mugihe kirekire. Turimo kandi kwagura igice-cyagatatu cya NADCAP kwemererwa kubikorwa bya ECM byihariye, ntabwo byubahirizwa gusa muri rusange. Kuberako mumirenge nka hydraulics yo mu kirere cyangwa kuvoma amazi, "precision" ntabwo bipimirwa muri micron yonyine. Bipimirwa mugihe gito hagati yo gutsindwa. Mugihe cyo hejuru. Mu kwizerana.
Niba umushinga wawe utaha urimo ibice bya cobalt-nikel, sisitemu yumuvuduko mwinshi wa sisitemu, cyangwa geometrike ya superalloy aho uburyo busanzwe bwa plateau -uruganda rutunganya amashanyarazi neza ubuhanga bugomba gukorwa kuva kumunsi wambere. Ntabwo wongeyeho nkibitekerezo.
