Ubuhinzi bugezweho ntibukigendera ku bushishozi bwonyine. Ikora ku bice byuzuye - indangagaciro zumuvuduko zifata akabari 350 zidatemba, inzu ya pompe ya piston yakozwe kugeza ± 0.01 mm kwihanganira, imashini ya shitingi ya shitingi yahimbwe kugirango irwanye ubutaka bwangiza amasaha 12,000+. Iyo ibi bice binaniwe, igihe cyo hasi ntipimwa muminota-gipimwa kuri hegitari yatakaye, gusarura amadirishya yabuze, hamwe na lisansi yapfushije ubusa.
Niyo mpamvu icyuho nyacyo mubikorwa byuruganda rukora imashini zubuhinzi ntabwo ari ubushobozi bwumurima cyangwa GPS neza. Nibikoresho byihishe inyuma yibice byingenzi byubutumwa: ibyashyinguwe imbere muri hydraulic manifolds, bigashyirwa munsi yimigozi ya traktori, cyangwa bigashyirwa imbere mumapompo yo kuhira cyane. Twabonye imirima yo muri Saskatchewan itinda guhinga kuko nozzle imwe ya cobalt-alloy nozzle yacitse munsi yumukino wo gusiganwa ku magare. Twarebye amakoperative yumuceri yo muri Aziya yepfo yepfo asibanganya ibyiciro byose byimyitozo yimbuto nyuma yimfatiro zidasanzwe za pompe zashize mugihe cyo kuvura ubushyuhe. Ibi ntabwo ari "kunanirwa kw'imashini." Nibintu-bidahuye-ntibikemurwa na traktori nini, ahubwo nibikorwa byubwenge buke.
Impamvu ibice byicyuma bisobanura neza ubuhinzi
Ibikoresho byubuhinzi bikora bikabije: gutangira subzero muri Alberta, ubushyuhe bwa 50 ° C muri Andalusiya, guhora kunyeganyega kumirima iremereye yibumba muri Berezile. Ibisanzwe bisanzwe. Ibyuma bitarekuwe neza. Ibice rusange bya CNC ntibibura uburinganire bwa microstructural bukenewe mukurwanya umunaniro urenga 10,000.
Inyungu-nyayo yunguka ituruka kubintu bine bisabwa:
- Igipimo gihamye-Nta kurwanira nyuma yo kuvura ubushyuhe cyangwa gupakira hydraulic igihe kirekire
- Guhuza ibyuma-Gusubiramo-gusubiramo gusubiramo gukomera, imiterere yintete, no kurwanya ruswa
- Imikorere ya geometrie-Inzira yimbere yimbere hamwe nubuso bwa Ra ≤ 0.8 µm, gufunga hejuru ya mm 0.005
- Kugenzura inzira ikurikirana-Ibikoresho byuzuye, raporo ya CMM kuri buri kintu, kwemeza GD&T mbere yo gukata mbere
Inganda nyinshi zimashini zubuhinzi zitanga hanze cyangwa gutunganya - ariko gake byombi. Icyo cyuho gitera amakosa ya handoff: guta umucanga bigabanuka bitateganijwe mugihe cyo gukonjesha, hanyuma iduka rya CNC ryishyura no kuvanaho imigabane igabanya ibice bikomeye byurukuta. Igisubizo? Igice cyatsinze igenzura ariko cyananiwe guturika ku gipimo cya 80%.
Ibyiza Byuzuye: Gutera, Gukora, Kurangiza munsi yinzu
Bamwe bavuga ko ubuhanga butera guhuza vertical. Ariko mugihe inzu yawe ya piston pompe igomba kuba yujuje AMS 5387 cobalt alloy spes * kandi * ikarokoka miriyoni 200 zumuvuduko ukabije, kugabana imirimo kubacuruzi batatu bigwiza ibyago - ntabwo ari byiza.
Twakurikiranye prototype 47 yubaka TEM-1 yubuhinzi OEM. Imishinga yacungaga impera-iherezo-uhereye ku ishoramari binyuze muri axe nyinshi CNC, kuvura ubushyuhe, hamwe na passivation - byatanze 63% bike byo guhindura imashini kandi bigatanga umusaruro wambere 91% byigihe. Abacungwa mumasoko atandukanye hamwe namaduka yimashini bagereranije 3.2 gusubiramo imirimo kumuryango.
Ibi ntabwo bijyanye no korohereza. Byerekeranye no kugenzura kugenzurwa na fiziki:
- Gutera ibipimo biramenyesha mu buryo butaziguye imashini-nta gukeka ko guhinduranya cyangwa kugabanuka
- Ubushyuhe bwo kuvura ubushyuhe bwateganijwe kugirango buhuze nuburyo bukurikira bwo gutunganya, birinda guhangayika gusigara
- Kurangiza ubuso (urugero, electropolishing kumibiri ya pompe idafite ingese) itangira * mbere yubugenzuzi bwa nyuma-kubwibyo inenge zigaragara ntizitwikire amakosa yo munsi y'ubutaka
Umukiriya umwe - uruganda rw’iburayi rukora imashini yisunika-yagabanije inshuro 40% yo gusimbuza hydraulic valve gusimbuza inshuro 40% nyuma yo kuva mu byuma rusange bikajya mu nzu ya T800 ishingiye kuri cobalt ikozwe na annealing ihuriweho. Ibikoresho byabo byo kubungabunga byerekanaga zeru zidashyirwaho kashe mu mezi 18 - bitandukanye n’ibyabaye mu mwaka ubanza.
Niki Mubyukuri Mubyukuri Guhitamo Ibikoresho (Kurenga "Icyuma kitagira umuyonga")
"Ibyuma bitagira umuyonga" ntacyo bivuze bidafite imiterere. AISI 304 yangirika vuba muri nitrate ya ammonium. ASTM A536 icyuma cyangiza gitakaza imbaraga zingana hejuru ya 120 ° C. Nyamara amatsinda yo gutanga amasoko aracyerekana "ingese" kuri RFQs - kandi akishyura amafaranga yo gukora mugihe ibice byinjiye mubigega by'ifumbire.
Imikorere nyayo-isi ishingiye ku byemezo bitatu:
- Urwego rwa Alloy rwahujwe nuburyo bwo gutsindwa: Amavuta ya Cobalt-nikel (nka AMS 5387) kugirango isuri-yangirika muri pompe zoroshye; ferritic stainless ibyuma byo kurwanya chloride muri sisitemu yo kuhira ku nkombe
- Inzira yo gutunganya ihujwe na geometrie: Gushora imari kumibiri yoroheje ifite uruzitiro rwimbere rufite imbere; umusenyi wo guta ibishingwe binini bikenera kunyeganyega
- Kugenzura nyuma yuburyo bugenzurwa nibikorwa: Kugerageza umunyu-spray * nyuma ya * passivation - ntabwo mbere gusa; ubugenzuzi bwa ultrasonic * kuri buri kintu *, ntabwo ari ingingo yambere
Muminsi ishize dufashije uruganda rukora ibikoresho byo gutunganya ingano muri Amerika gusimbuza icyuma cyatsinzwe na carbone-ibyuma. Abatanga isoko rya kera bavuze "ibyuma bikomeye." Isuzuma ryacu ryerekanye ko gutsindwa kwabo kwari hydrogène yatewe no gufata amasahani adakwiye. Twahinduye mubisanzwe 4140 hamwe na hydrogène yagenzuwe-kandi twongereye ubuzima bwa serivisi kuva kumezi 4 kugeza kumezi 22 mubikorwa bikomeje.
Guhitamo Umufatanyabikorwa: Reba Impamyabumenyi Yashize, Reba Akazi
ISO 9001 ni imigabane. Ikitandukanya abatanga isoko byizewe nuburyo bakemura ibidasobanutse. Barabaza * kuki * kwihanganira gukomera - cyangwa kubivuga gusa? Bashobora kwerekana amakimbirane ya GD&T mbere yo guca ibyuma? Babika imibare yubushyuhe bwibanze kuri buri kintu cyoherejwe?
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Buri cyegeranyo kijyanye n'ubuhinzi gikurura isuzuma ryakozwe ninganda. Dushushanya buri kintu kiranga umutwaro wacyo: kwihanganira mm 0,02 kuri positif yo kwishyiriraho ntabishaka-birinda kwambara nabi biterwa no kwambara nabi muri 200-hp ya PTO. Niba igishushanyo kitavuze ibyo, turabaza. Niba ibisobanuro bivuguruzanya na casting bishoboka, turasaba ubundi buryo bushyigikiwe namakuru ya FEA - ntabwo ari igitekerezo.
Iyo disipuline yerekana mugutanga: 98.3% kurangiza mugihe cyo gukora ibicuruzwa bito bito (50-500 pcs / lot), hamwe nibisobanuro byuzuye kugeza kumatanura hamwe na verisiyo ya gahunda ya CMM. Oya “hafi yiteguye.” Nta “ukurikiza igihe cyo kuyobora ibintu.” Gusa byanditse, bisubirwamo.
Guhinga neza ntabwo byubatswe mumurima. Yahimbwe munganda, isya muri selile ya CNC, kandi yemejwe muri laboratoire ya metero - kera cyane mbere yuko imbuto yambere itera ubutaka. Uruganda rukora imashini zubuhinzi ruyobora neza neza ntirwohereza ibice gusa. Yohereza ibizaba.
