Iyo injeniyeri n'abashinzwe gutanga amasoko bashakisha a uruganda rukora umucanga itanga ihame ryimiterere, guhuza metallurgjique, no gutanga ku gihe - ntabwo ari casting gusa - akenshi bahura nikibazo kimwe: abatanga ibicuruzwa benshi bafata guta umucanga nkibicuruzwa. Ariko muri hydraulic manifolds, amazu ya pompe yumuvuduko mwinshi, cyangwa shitingi ya winch yo hanze, umuvuduko wa mm 0,15 kwihanganira cyangwa microstructural idahuye ntabwo "yegeranye bihagije." Nukunanirwa kumurima.
Impamvu Gutera Umucanga Biracyafite akamaro-Iyo Bikozwe neza
Gutera umucanga bikomeje kuba inzira ihenze cyane kubunini buringaniye, bigoye-geometrie ferrous hamwe na ferrous ibice birenga 5 kg-cyane cyane iyo uburebure bwurukuta butandukanye, ingirabuzimafatizo zimbere, zirakenewe, cyangwa ibivangavanze bigoye kubuza gupfa cyangwa uburyo bwa centrifugal. Ariko kwiringirwa gushingiye kubintu bitatu inganda nke zigenzura icyarimwe: ibikoresho fatizo bikurikirana, ubunyangamugayo bubi munsi yumuriro, hamwe no kwemeza ibipimo nyuma yo gutangira. Twabonye imishinga myinshi yatinze kubera ko utanga "wujuje ibyangombwa" yemeye ASTM A48 Icyiciro cya 35 cyicyuma cyumucyo utabanje kugenzura umubare wa grafite nodule - cyangwa wasibye radiografi yabanje gutunganyirizwa kumubiri wa cobalt-alloy valve yagenewe serivisi ya gaz-gaz.
Ubuhanga bwimbitse buvanze ntabwo bushobora kuganirwaho
Ntabwo guta umucanga byose bingana. Ibyuma bikozwe mubyuma cyangwa ibyuma bya karubone bikurikiza kugabanuka guteganijwe no kugabanuka kugabanuka. Cobalt-nikel ivanze nka AMS 5387 cyangwa T800? Barasaba igishushanyo mbonera gitandukanye, igipimo cyo gukonjesha gahoro, hamwe nuburyo bukurikiranye bwo kuvura ubushyuhe - cyangwa uzabona gucikamo ibice hagati ya CNC ya nyuma. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Abashakashatsi ntibasuka ibyuma gusa. Bemeza buri cyiciro cya T800 kurwanya ASTM F962 kubintu bya cobalt nubunini bwingano; Bakoresha thermocouple array yashyizwe mubibumbano kugirango binjire mugihe nyacyo cyo gushimangira; kandi bafata ingingo ya mbere kumasaha 72 mbere yo gukora kugirango bemeze kuruhuka. Niyo mpamvu amazu yabo ya piston pompe ya pisitori agera kuri Cpk> 1.67 kuri bores zikomeye-nimpamvu AMS 5387 cobalt alloy nozzles irokoka 12,000+ inzinguzingo zangiza.
Kwishyira hamwe guhagaritse gukemura ibibazo-byukuri byisi
Amaduka menshi yo guterera umucanga atanga imashini zindi-mashini. Ibyo bitera ibibanza bihumye: ububobere bwo hejuru bwihishe munsi yimashini, guhangayika bisigaye bitorohewe mbere yo kurangiza, cyangwa guhamagarwa kwa GD&T hagati yo gushushanya na gahunda za CNC. QINGDAO QIANGSENYUAN ikorera munsi yinzu - guta, guhuza imirongo myinshi CNC (harimo 5-axis ihuza ibishingwe bya pompe), kuvura ubushyuhe, hamwe no kurangiza hejuru nka HVOF ikingira cyangwa passivation. Mugihe umukiriya yohereje igishushanyo cyimodoka yimashini ya winch center shaft roller ifite uburebure bwa mm 0,025 kuri mm 280 ya OD, itsinda ryerekanye ko umwimerere wumucanga wumwimerere uzatera kuvanaho imigabane idahwanye. Bongeye gushushanya igishushanyo, bahindura ibyapa byibanze, hanyuma bakora igeragezwa - hanyuma bagenzura uruziga * nyuma yo guhinduka bikabije ariko * mbere yo gusya. Igisubizo: gukora zeru, kubahiriza byuzuye ingingo yambere.
Ubwiza ntibugenzurwa-Bwubatswe, Intambwe ku yindi
Impapuro zujuje ISO ntabwo zemeza imikorere igice. Niki? Igenzura ryanditse ku ngingo esheshatu zidashobora kuganirwaho: ibyinjira byinjira (hamwe nubushyuhe bwumubare wubushyuhe), kugenzura ubukonje bwumucanga wumucanga, ibiti byubushyuhe bwa shakeout, ikarita yerekana ubushyuhe nyuma yo gushushanya, CMM gusikana imibare ikomeye * mbere ya * na * nyuma * yo gukora, hamwe nigeragezwa ryanyuma-nkibipimo byapima imbaraga zumuriro kugeza kuri 1.5 ×. Buri raporo ihuza ibyateganijwe mbere yo kugura no gushushanya. Nta na kimwe kidasanzwe. Abakiriya bo muri Amerika ya Ruguru hamwe n’Uburayi bahabwa dosiye zuzuye za digitale: 3D scan yuzuye yerekana as-cast na geometrie ya nyuma, raporo yisesengura ryerekanwe kubice bivanze, hamwe nubushakashatsi bwashyizweho kashe. Niba igice cyananiranye, intandaro iragaragara-ntabwo yashyinguwe mubitekerezo.
Guhitamo Umufatanyabikorwa Ukurikira Umucanga-Ibyo Kubaza Noneho
- Ati: “Nyereka amakarita yawe atatu ya nyuma ya AMS 5387 - ingano nyayo yari ingana iki, kandi wabigenzuye ute?” (Niba bavuga imbaraga zingana gusa, genda.)
- “Urashobora gufata Cpk ≥ 1.33 kuri 0,05 mm kwihanganira imyanya kubintu biranga * na * bikorerwa murugo?” (Niba bashidikanya cyangwa bakavuga ngo "biterwa no gushushanya," inzira zabo ntizihamye.)
- "Nuwuhe mwanya muremure wo kuyobora umusenyi wa prototype - kuva PO kugeza kohereza ingingo ya mbere?" (Munsi yiminsi 25 byerekana igenamigambi rihuriweho; muminsi irenga 45 mubisanzwe bisobanura gukora hanze cyangwa gukora ubushyuhe.)
Yizewe uruganda rukora umucanga ntabwo isezeranya gutungana. Iteganya uburyo bwo gutsindwa - kandi yubaka gutahura, gukosora, no gukumira muri buri ntambwe. Itandukaniro riri hagati yo kwakira abakinnyi… no kwakira ikizere.
