Iyo abajenjeri bagaragaje umusenyi wibice byicyuma-cyane cyane muri sisitemu ya hydraulic, ibikoresho bya peteroli na gaze, cyangwa inteko zipompa ziremereye - ntabwo bahitamo inzira gusa. Bahisemo umufatanyabikorwa wunva uburyo imiterere yintete igira ingaruka kumibereho yumunaniro, uburyo guhuza ibumba bigira ingaruka kubisubirwamo, nimpamvu kwihanganira mm 0,15 kumiturire ya cobalt-alloy inzu ya silinderi ntabwo ari icyifuzo-nibisabwa mumikorere idashobora kumvikana. Aho niho uburambe-nyabwo butandukanya abatanga ubushobozi nukuri uruganda rukora umucanga abafatanyabikorwa.
Impamvu Gutera Umucanga Biracyatsindira Inshingano-Ibikorwa Byinganda
Bamwe batekereza ko guta umucanga ari iby'umurage usabwa gusa. Ariko twabonye bitanga intsinzi isubirwamo aho izindi nzira zananiranye: igice kinini cyicyuma gikenera imbaraga zo guhangana nubushyuhe mumashanyarazi; amazu yicyuma hamwe numuyoboro wo gukonjesha imbere bidashoboka kumashini post-cast; ibice bitagira umwanda bisaba imbaraga za isotropic mubice byimbitse. Urufunguzo ni ukugenzura - ntabwo ari ugusuka ubushyuhe gusa cyangwa igihe cyo guhinda umushyitsi, ahubwo hejuru yumunyururu wose: guhuza umusenyi wicyatsi kibisi, guhuza ibyingenzi, guhuza amarembo yo gutembera kwa laminari, hamwe ningaruka zo kugabanuka nyuma yo kugabanuka byagenzuwe no gushushanya ikarita.
Mu mushinga umwe uherutse, OEM yu Burayi yari ikeneye imibiri 42 yumuvuduko wa ASTM A351 CF8M. Ababitanze mbere babuze guhamagarwa kwa GD&T kumyobo itatu ya flange-itera inteko kwivanga mubizamini byanyuma. Twarayifashe mugihe cyo gushushanya kwemeza, duhindura igishushanyo mbonera cya cope ingana na 0.8 °, hanyuma twongeraho urwego rwa kabiri ruhuza pin. Igisubizo: gukora zeru mubice 120. Urwo rwego rwo gutabara ntirushoboka hatabayeho kwishyira hamwe kwuzuye - kuva kuvanga umucanga kugeza CNC kurangiza gutunganya hasi.
Aho Ubuhanga bwibikoresho buhura na disipulini
Amavuta ya Cobalt-nikel nka AMS 5387 na T800 ntabwo asubiza mubikorwa rusange byo gushinga. Ahantu ho gushonga cyane, amazi make, hamwe nubushyuhe bukabije bwo guturika bisaba uburyo bwihariye: igipimo gikaze, ibipimo byashushe hejuru ya 250 ° C, hamwe nigipimo cyo gukonjesha gikurikiranwa hifashishijwe amashyanyarazi yashizwemo. Twasutseho kg zirenga 1.700 za T800 mumezi 18 ashize-kandi buri cyiciro gitwara ibisobanuro byuzuye: umubare wubushyuhe, raporo yisesengura rya ecran, hamwe namafoto ya microstructure yerekana amaboko ya dendrite hagati ya 25 µm.
Iyo disipuline irenze ibirenze gukemura. Kubyuma bikoreshwa mumashanyarazi ya winch center shaft rollers, turagenzura ibara rya grafite nodule (ASTM E2567) hamwe na ferrite / pearlite ratio * mbere yuko * gutangira. Kubera iki? Kuberako 5% ya pearlite irenze yongera igihe cyo gusya hejuru ya 37% kandi igabanya ubuzima bwibikoresho mo kabiri. Turabipima - ntabwo tubitekereza.
Icyo "Icyitonderwa" mubyukuri bivuze mubikorwa
Icyitonderwa mu guta umucanga ntabwo ari ugukurikirana kwihanganira urwego rwa micron ku bice binini. Byerekeranye no guhanura. Ubushobozi bwacu busanzwe: ± 0.3 mm kumiterere igera kuri mm 600, ± 0.5 mm kubice birenga mm 1200 - hamwe na raporo ya CMM yagenzuwe na raporo yingingo ya mbere irimo nta kiguzi cyinyongera. Ariko icy'agaciro ni ibitekerezo byacu byo gusubiramo: niba igishushanyo cyawe gisaba 12.5 µm Ra kurangiza kuri bore ikozwe, tuzashyira ahagaragara niba as-cast izakenera mm 2,1 cyangwa 3,4 mm yo kuvanaho imigabane-nuburyo ibyo bigira ingaruka zo kugabanuka kumafaranga no gushyira riser.
- Umuvuduko wumuvuduko: GD & T-yubahiriza intebe hejuru, igenzurwa nogukoresha ikirere kandi ikageragezwa kuri 1.5 × igitutu cyakazi
- Inzu ya pisitori ya pisitori: Bore yibanze kuri 0.025 mm TIR muburebure bwa mm 450
- Cobalt alloy nozzles: Ubunini bwurukuta bugenzurwa muri mm 0.18 mm kuri mm 8 byibura
Ntabwo dufata gukina no gutunganya nkibice bitandukanye. Nibyiciro bikurikiranye murwego rumwe-nuko rero programu ya CNC asubiramo as-CT scan mbere yo kwandika inzira yambere. Nuburyo wirinda kuvumbura porosity munsi yubutaka bukomeye nyuma yamasaha 14 yo gusya.
Guhitamo Umufatanyabikorwa Utanga-Ntabwo ari amasezerano gusa
A uruganda rukora umucanga ugomba gusubiza ibibazo bitatu mbere yuko usinya PO: Birashobora kwihanganira cyane kuri geometrie igoye cyane * mubikorwa *, ntabwo ari prototype gusa? Bafite ibyemezo byabo-cyangwa bashingira kumpapuro zitanga isoko? Kandi iyo gutandukana kurwego bibaye, basangira amakuru-yimpamvu (ibiti byinjira mumucanga, gushonga umurongo wo gusesengura, amakarita ya X-ray) cyangwa bagatanga gusa urupapuro rwibikorwa bikosora?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora munsi ya ISO 9001: 2015 hamwe na protocole yubugenzuzi kuri buri gice cya casting. Buri kintu kibisi cyemewe, buri gice cyavuwe nubushyuhe cyinjiye, buri kintu cyarangiye kigenzurwa neza munsi ya 10 × gukuza. Dukorera abakiriya muri Amerika ya Ruguru, Uburayi, no mu majyepfo y’amajyepfo ya Aziya - ntabwo binyuze mu bunzi, ahubwo binyuze mu biganiro byerekeranye n’ubuhanga: gusobanura GD&T, gutanga ibitekerezo mu masaha 48, no kuvugurura buri cyumweru hamwe n’ifoto yerekana ibimenyetso byingenzi.
Igihe kizaza cyo guta umucanga neza kiri mubikorwa byogukora-aho guterana bisobanura geometrie nubunyangamugayo, kandi gutunganya bitanga ubuso bukora kandi buhuye neza. Ibyo bisaba ubushishozi bwimbitse, guhuza inzira, hamwe no kwihanganira zeru kubitekerezo. Niba umushinga wawe utaha usaba ibice bikora - bidakwiriye gusa - tangira muburyo busobanutse, ntabwo ari ibiciro gusa.
