Iyo ba injeniyeri bagaragaje gushora ibice byinganda serivisi za hydraulic valves, amazu ya pompe, cyangwa shitingi ya winch, ntabwo bagura ibyuma gusa-bagura ituze ryikigereranyo munsi yumuvuduko wa bar-300, ubunyangamugayo bwa microstructure nyuma yo kuvura ubushyuhe, hamwe no kutihanganira zeru kubera ububobere muri cobalt-nikel alloy nozzles. Twabonye imishinga myinshi ihagaze kuko utanga isoko yasezeranije "casting casting" ariko agatanga ibice byananiwe kwemezwa na CMM mugice cyanyuma cyo kugenzura-cyane cyane kuri AMS 5387 cyangwa T800 yo mu cyiciro aho ibyuma bikomera hamwe nicyerekezo cyogutwara ingano bigira ingaruka mubuzima bwumunaniro.
Impamvu Gutera Ishoramari Atari Ubundi buryo-Ni ukubuza Sisitemu
Gutera ishoramari ntangarugero aho guta umucanga bidafite ibyemezo kandi gutunganya CNC bigera kumipaka yibikoresho. Ariko intsinzi itangira kera mbere yuko ibishashara bishonga. Ku kigo cyacu i Qingdao, buri cyegeranyo gitangirana no kurinda amarembo ya metallurgiki: ibikoresho fatizo bigenzurwa * mbere yo kuvanga, ntabwo nyuma yo guterwa. Twanze ibyiciro ndetse no 0,02% gutandukana muri chromium cyangwa molybdenum yibintu bivangwa na cobalt-kubera ko iyo marike ihitamo niba icyuma cya AMS 5387 kibaho 12,000 cyumuriro wa pompe yo hanze.
Twapimye igipimo cyo kugabanuka hejuru ya 47 yubushyuhe bwinshi bwo gushora ibyuma bidafite ingese-kandi twasanze gutandukana bidashoboka. Ikurikirana mu buryo butaziguye igishushanyo mbonera, ibishishwa byumye, hamwe nubushyuhe bwihuse. Niyo mpamvu impapuro zacu zitunganya zifunga ibipimo 19-ntabwo "suka ubushyuhe" n "" igihe cyo gukonja. " Kurugero, inzu ya pisitori ya pisitori isaba ibyerekezo bigenzurwa kugirango wirinde microporosity. Ikigereranyo cyo gukonjesha 1,2 ° C / min gihindura intera ya dendrite ya 8,6 µm. Ibyo birapimwa. Ibyo birashoboka.
Kwishyira hamwe guhagaritse gukemura ibibazo byububabare-Ntabwo ari Kwamamaza gusa
Bamwe mubatanga ibikoresho byo gutunganya, kuvura ubushyuhe, cyangwa kurangiza hejuru. Ibyo bivuna kubazwa. Iyo igitutu cyimyubakire yimyubakire nyuma yubushyuhe, umukanishi yashinje caster; caster yashinje umucuruzi w'itanura. Dufite intambwe zose uko ari eshatu. Utugingo ngengabuzima twa CNC dukora hamwe n'umurongo wo guteramo - bityo igice cyashizwe saa munani zuzuye, zikoreshejwe nabi, zorohereza imihangayiko, zirangije imashini, na CMM-zisikana saa yine z'ijoro. Umukoresha umwe. Ibiti bimwe. Indangamuntu imwe.
Ibi ntabwo byoroshye-ni igenzurwa na fiziki. Gukora imashini mugihe bikiri mubushuhe birinda gukora imirimo yo kugabanya ibibazo bisigaye. Twagabanije ibipimo by'ibisigazwa ku kigero cya 63% ku rufatiro rwa pompe idafite ibyuma duhindura kurangiza-guhinduka kubaho mu masaha 4 ya annealing. Kandi yego - twandika ibidukikije biduka-ubushyuhe n'ubushyuhe kuri buri cyiciro. Kuberako 5 ° C swing ihindura igipimo cyo kwambara igikoresho kuri T800 ikomye kuri 17%.
Ibyo abakiriya bagerageza mubyukuri (n'impamvu bananiwe abandi)
Abaguzi ntibabaza ngo "Ukora ishoramari?" Barabaza bati: "Urashobora gufata mm 0.015 mm kuri 320-mm ya diametre ya bore hamwe na 3.2 µm Ra kurangiza, ukoresheje cobalt alloy, hanyuma ugatanga ibyemezo byuzuye wongeyeho raporo ya CMM kuri ASME Y14.5?" Dore itandukanya irangizwa n'amasezerano:
- Kwemeza GD&T bibaho mbere yuko ibikoresho bitangira—Ntabwo nyuma yingingo ya mbere. Dushira ahabona amakimbirane ya datum, kwihanganira umwirondoro bidahuye nubunini bwigikonoshwa, cyangwa radii cyane kugirango ceramic slurry itemba.
- Nta "bisanzwe" bivura ubushyuhe. Duhindura umwanya wo gushira ukurikije ubunini bwigice - ntabwo ari urutonde rwihariye. Urukuta rwa mm 45 rusaba uburebure bwa 2,3 × kurenza urukuta rwa mm 12 kugirango bingane ubushyuhe hakurya.
- Ibipimo byose bikomeye bigenzurwa kabiri: CMM ya geometrie, igereranya optique yo gusobanura inkombe - kuko uburebure bwa burr bufite akamaro kashe.
Twagize abakiriya bahinduranya umushinga wo hagati nyuma yo kuvumbura uwabatanze mbere yakoresheje ibyuma rusange "bitagira ibyuma" aho gukoresha raporo yubushyuhe nyabwo. Twashyizeho kashe kuri buri cyemezo hamwe nindangamuntu, dusuka umubare, hamwe na test ya coupon. Nta na kimwe kidasanzwe.
Aho Precision ihura nibikorwa - Noneho na Ibikurikira
An gushora ibice byinganda yizera ikizere atari mu gatabo - ahubwo binyuze muburyo ikemura ikibazo cya mbere kidahuye. Igihembwe gishize, hydraulics yu Burayi OEM yatwoherereje igishushanyo hamwe guhamagarwa kwa GD&T bivuguruzanya kumubiri wa valve. Aho gusubiramo buhumyi, twashushanyije intego yibikorwa, dusaba ubundi buryo bubiri bushobora gukorwa, kandi dukoresha FEA kuri byombi kugirango twerekane itandukaniro ryo kugabana. Bahisemo Ihitamo B - bagabanya igihe cyo guterana 22%.
Urebye imbere, turimo kwagura ISO 13485 yiteguye kubuvuzi bwa cobalt yo mu rwego rwo kwa muganga no kwemeza ibikorwa bya Hybrid casting-mashini ikora kubatwara turbine vane. Ariko ibyibanze byumunsi ntibigihinduka: gutanga ibice byatsinze ibizamini bikora-ntabwo ari igenzura gusa. Niba umushinga wawe utaha ukeneye ububiko bwumuvuduko, inzu ya silinderi, cyangwa ibikoresho bya cobalt alloy ibice byubatswe mubyukuri-isi imizigo hamwe nubuzima bwubuzima, tangira ukoresheje ibintu bifatika, ntabwo ari amagambo yo kwamamaza.
