Iyo ba injeniyeri bagaragaje ibice bya carbone ishoramari, ntabwo batumiza ibyuma gusa-barasaba gutekana kurwego munsi yumuvuduko wa hydraulic bar 350, guhuza microstructural kurwego rwibice 500, hamwe nubusugire bwubuso burokoka umuvuduko ukabije wamasaha 12,000. Urwo rwego rwimikorere ntiruva mubikorwa rusange. Birasaba a uruganda rukora ibyuma bya karubone yubatswe hafi ya disipuline ya metallurgjiya - ntabwo ari ubushobozi bwo guta gusa.
Impamvu ishoramari ryatsindiye gutsindira ibyuma bya Carbone
Gutera umucanga byiganjemo umusaruro mwinshi wa karubone - ariko birananirana aho geometrie igoye ihura nuburemere bwimikorere. Twabonye inzu ya pisitori ya pisitori yangwa inshuro ebyiri: ubanza kuri mm 0,18 mm yuburebure bwurukuta muri zone ya port ya valve, hanyuma kuri micro-porosity hafi ya zone yibasiwe nubushyuhe nyuma yo kugabanya ibibazo. Gushora imari byakemuye byombi. Igikoresho cyacyo ceramic gitanga ± 0,05 mm kwihanganira umurongo kubintu nkimiyoboro yo gukonjesha imbere hamwe na bores yibanda cyane - idafite inguni cyangwa imirongo yo gutandukana. Ikirushijeho kunenga, kugenzura ibyerekezo bigabanya kugabanya imyenge igabanutse mubyimbye-byoroheje bikunze kugaragara mumibiri ya valve yumuriro hamwe na winch center shaft. Ubucuruzi? Igiciro kiri hejuru kuri buri gice. Kwishura? Zeru ikora kuri GD & T-kunegura imibare. Kubisabwa aho gutsindwa bivuze igihe cyo kugura kigura $ 18,000 / isaha, iyo mibare ntabwo ishobora kuganirwaho.
Ubunyangamugayo bwibintu butangira mbere yo gusuka
Ibyuma bya karubone birananirana - bitatewe nubuhanga buke bwo guta - ahubwo biva kubitungwa bidahuye. Twigeze gukurikirana ibice byagarutsweho muri ASTM A216 WCB pompe ya pompe ya manganese gutandukanya manganese mubice bya bilet biva munganda eshatu zitandukanye. Uyu munsi, buri gushonga bitangirana nibyemezo 1020-1045 byemewe, bigenzurwa hakoreshejwe OES spectroscopy mbere yo kwishyuza. Icy'ingenzi, dufatanya-gushyushya-gutunganya ibizamini hamwe nibizamini byabo bihuye-nta "sample sample" yibwira. Ibi byerekana imyitwarire ihinduka hagati yigice na raporo yikizamini cya mashini. Kuri AMS 5387 cobalt alloy ibice (akenshi byinjizwa mubiterane byibyuma bya karubone), dukomeza gushakisha inshuro ebyiri: icyiciro kimwe cya cobalt nozzle, ikindi cyamazu yicyuma cya karubone - hamwe ninyandiko zuzuye zihuza byombi mugiti kimwe cyo gutunganya ubushyuhe. Nta bigufi. Nta cyiciro cyo kuvanga.
Aho Casting irangirira, Icyerekezo gitangirira
Gukina neza ntabwo byarangiye kuri shakeout. Birarangiye iyo 0.002 ″ hejuru yubuso hejuru yumuvuduko wa valve intebe yatsinze helium yamenetse kuri 10−9 mbar · L / s. Ibyo bisaba guhuza vertical - ntabwo ari ugutera gusa, ahubwo gutunganya CNC, kuvura ubushyuhe, na metero munsi yinzu. Ikigo cyacu ISO 9001 gikora 5-axis yo gusya nyuma yo gushyirwaho kugirango ifate umwanya wukuri muri mm 0,01 kuri 12-ya flange. Dushiraho imashini yanyuma yo gufunga * nyuma * yo kugabanya imihangayiko, ntabwo mbere - gukuraho inzira zintambara zatewe n'inzira. Igenzura rya CMM ntabwo ari irembo rya nyuma; yashyizwemo hagati. Nyuma yo gutunganya ibintu bigoye, turagenzura kunenga bore yibanze. Gusa noneho dukomeza kurangiza gukata. Ibi bifata kugoreka ubushyuhe hakiri kare - bizigama amasaha 72 yataye igihe cyo kurangiza kumazu manini.
Kwemeza-Isi Yukuri, Ntabwo Kwuzuza Impapuro gusa
Abakiriya barabaza bati: “Urashobora gukoresha amashanyarazi ya T800 ya cobalt yometse mu byuma bya karubone?” Yego - ariko kubera gusa ko twemeje ibyuma bidasa nicyuma binyuze muri cycle 500 yumuriro (-40 ° C kugeza + 250 ° C) hamwe no gushushanya ikarita ya ultrasonic. Barabaza bati: “Inzu yawe ya silinderi irokoka isuri yo mu mazi yo mu nyanja?” Yego - kubera ko tubagerageza mukuzenguruka kwacu kavanze hamwe na 12% bya silika kuri 2800 RPM mumasaha 400, gupima igihombo cyibikoresho ukoresheje laser profilometry. Icyemezo gifite akamaro, ariko imyitwarire yumurima ifite akamaro kanini. Niyo mpamvu ibyoherejwe byose birimo gukurikiranwa byuzuye: nimero yo gushonga, indangururamajwi-yerekana indangamuntu, serivise ya raporo ya CMM, hamwe na sisitemu yo kwiyandikisha-ntabwo ari icyemezo gusa.
Kubutumwa-bukomeye bwa carbone ibyuma bishora ibice, ubushobozi ntibupimirwa muri tonnage cyangwa amashusho kare. Bipimirwa muri microns yo kwihanganira byakozwe, amasaha ya serivisi yatanzwe, no kunanirwa byakumiriwe mbere yo gukora bwa mbere. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora nka a uruganda rukora ibyuma bya karubone aho metallurgie itwara imashini - kandi aho buri casting itwara uburemere bwibikorwa byayo, ntabwo ari urupapuro rwihariye.
