Iyo ba injeniyeri bagaragaje a uruganda rukora ibyuma, ntabwo batumiza amazu gusa-barimo kubona ubunyangamugayo bwubatswe munsi ya 300+ bar hydraulic yumuvuduko, guhagarara neza nyuma yo gusiganwa ku magare yumuriro, no kurangiza hejuru birwanya kwambara nabi. Niyo mpamvu precision ifite akamaro kuruta igiciro. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze imashini zirenga 12,000 za pompe ya pompe ya pompe ya pompe ya pompe ya pompe ya pompe ya pompe ya pisitori yo gucukura ibyuma byo hanze - buriwese ufite kwihanganira mm 0.015 mm kwihanganira bore, byagenzuwe na CMM za Zeiss mbere yo kuvura ubushyuhe.
Ni ukubera iki guta ibyuma byananiranye-nuburyo gutondeka neza birinda
Kunanirwa kwumurima byinshi bikomoka kumpamvu eshatu: micro-shrinkage porosity hafi yibice byimbitse, gukwirakwiza grafite ya nodule idahuye mubyiciro byicyuma, cyangwa imashini iterwa no gusigara muri geometrike yoroheje. Turabona buri cyumweru mugihe cyo gusuzuma ibintu byinjira-cyane cyane hamwe na fagitire ya GGG-40 itemewe kuva munganda zitari ISO. Igisubizo cyacu gitangirira hejuru: dukomora gusa EN-GJS-400-18-LT yemejwe nicyuma cyimyanda itangwa nabagenzuzi bagenzuwe, hamwe nibice byose bikurikirana kugeza kuri raporo ya chimie. Buri gishonga gikora isesengura ryerekana; buri kasting ikonjesha kumurongo wagenzuwe-ntabwo igorofa yububiko - kugirango ugabanye imihangayiko yimbere.
Noneho haza inyungu ya Hybrid inzira. Bitandukanye n'amaduka meza yo guteramo, duhuza umusenyi hamwe na biti-bitanu CNC irangiza mukigo kimwe. Igikoresho cya hydraulic valve igeze nkumukino utoroshye. Mu masaha 72, biroroha guhangayika, bikozwe kugeza kumuhamagaro wa nyuma wa GD&T (harimo kwihanganira imyanya nyayo ya ± 0,02 mm kuri mwobo 16 uzamuka), no kurasa-kurasa kubera guhangayika hejuru. Nta ntoki. Nta gutandukanya ibipimo hagati y'ibikorwa. Uku kwishyira hamwe guhagaritse kugabanya umwanya wa 38% nu munyururu gakondo utanga-kandi bikuraho "ninde ubishinzwe?" icyuho iyo inzu yamenetse kuri 250 ° C.
Aho amavuta ya cobalt ahurira nicyuma - n'impamvu ikora
Porogaramu zimwe zisaba ibikoresho byombi munteko imwe. Tekereza umusingi wamavuta ya pompe ya fondasiyo: shingiro igomba gukuramo vibrasiya (ubushobozi bwicyuma cya ductile fer), mugihe icyicaro cyumuvuduko mwinshi gisaba kobalt alloy's resistance. Twabanje gutera ibyuma, hanyuma CNC-imashini isobanura neza guhuza imifuka ya AMS 5387 cobalt alloy insert. Imigaragarire ya geometrie ntabwo yishakiye - ikurikiza amabwiriza ya ASTM F2213 yo kwagura ubushyuhe budahuye. Twemeje iki gishushanyo mubice 47 byoherejwe mumirima ya Koweti. Zeru-kashe-intebe yo gusiba nyuma y'amezi 18 ikomeza gukora.
Ibi ntabwo ari theoretical. Yavutse mugupima: gusiganwa ku magare kuva kuri -20 ° C kugeza kuri 280 ° C, gupakira umunaniro wa cycle 10,000, no kugenzura ultrasonic ya buri murongo winjizamo. Abakiriya barabaza bati: “Urashobora gusudira cobalt mu cyuma?” Turasubiza: "Ntabwo - dukora injeniyeri kugirango gusudira ntibikenewe." Ngiyo itandukaniro riri hagati yo guhimba no guhuza imikorere.
Ukuntu gutanga-nyabyo kwisi bisa-ntabwo ari udutabo
OEM yo muri Amerika y'Amajyaruguru yari ikeneye 217 winch center shaft rollers yimodoka yubuhanga bwa arctique. Ababitanze mbere yabuze igihe ntarengwa kubera inenge yo guta umucanga muri radiyo ya flange. Twakiriye PO hamwe nibintu bibiri: twakoraga ingingo-yambere yo kwemeza ku gishushanyo cyabo * mbere yo gukoresha ibikoresho, kandi twohereza ibice 100% byagenzuwe hamwe na raporo ya CMM kugiti cye - ntabwo ari icyemezo cyo guhuza gusa.
- Umunsi wa 1: Isubiramo rya GD&T ryerekanye umushinga utari mwiza utera impinduka zingenzi - twasabye ko hahindurwa 0.8 ° byongeweho igiciro cya zeru ariko bivanaho 92% yikigereranyo cyo kwanga mukigereranyo
- Umunsi wa 12: Abakinnyi 5 ba mbere batsinze igenzura rya radiografiya; isesengura rya microstructure ryemeje igipimo kimwe cya pearlite / ferrite kuri ISO 945-1
- Umunsi wa 28: Ibice 217 byose byoherejwe hamwe na numero yuruhererekane rwa laser, inyandiko yikizamini gikomeye, no guhuza amakuru kuri buri bore ikomeye.
Ntamafaranga yihuse. Nta bicuruzwa bitwara ibicuruzwa byo mu kirere. Kugenzura ibyakozwe gusa - kuva mubikoresho fatizo nimero kugeza kubipfunyika bwa nyuma. Ngiyo amakipi yo gutanga amasoko yo kwizerwa akurikirana mubyukuri: ku gihe-cyuzuye (OTIF) ≥99.3% mugihe cya 2023–2024.
Guhitamo uruganda rukora ibyuma-birenze ibyemezo
ISO 9001 ni imigabane. Ikitandukanya abafatanyabikorwa nuburyo bakemura ibidasobanutse. Mugihe umukiriya wu Burayi yatwoherereje igishushanyo-cyashushanyije kurwego rwo gushushanya pompe yabugenewe-nta kintu gifatika, nta guhamagarwa kwihanganira, nta nsozero yo kurangiza-ntitwigeze tuvuga buhumyi. Twakoresheje isubiramo ryakozwe: twasabye EN-GJL-250 icyuma cyumuhondo aho kugirango ihindurwe neza kugirango ihindurwe neza, dusaba gusya impande aho kurambirwa nigihe cyihuta, kandi twerekana uburyo bwo kugoreka ubushyuhe muri SolidWorks Flow Simulation. Bemeje igishushanyo mbonera cyavuguruwe mu masaha 48.
Ngiyo agaciro katavuzwe: kugisha inama tekinike ibuza gukora. Ntabwo "tuzakora ibyo wohereje." Ariko "dore uko tuzabikora - byizewe, inshuro nyinshi, bikurikiranye." Waba ukeneye prototype 1 cyangwa 5.000 yumwaka, yaba inzu yawe yububiko ifite 500-hp turbine cyangwa valve yo kwigunga yo munsi yinyanja-physics yo guta ibyuma ntabwo ihinduka. Nta nubwo twegera.
Niba urimo gusuzuma a uruganda rukora ibyuma, baza ibibazo bitatu: Bashobora kukwereka raporo ya CMM kuva umusaruro wukwezi gushize? Bagenzura gukina no gutunganya - cyangwa gutanga hanze? Kandi mugihe igishushanyo cyawe gifite amakimbirane hagati yimbaraga nuburemere, batanga ibisubizo-cyangwa bakavuga ngo "ntibishoboka"? Ibisubizo birakubwira byose.
