Iyo ba injeniyeri bagaragaje uruganda rukora ibyuma serivisi, ntabwo zitumiza ibice gusa-zirimo kubona umutekano muke munsi ya 300-bar ya hydraulic imizigo, uburinganire bwa microstructure nyuma yo kuvura ubushyuhe, hamwe no kurangiza hejuru birwanya gutitira nabi mumazu ya pompe ya peteroli. Ngiyo ntarengwa abatanga ibicuruzwa benshi babuze. Twabibonye inshuro nyinshi: igice cyatsinze ubugenzuzi bwa CMM kubyoherejwe ariko bikananirwa kwipimisha kumikorere nyuma yamasaha 48 yakazi-kubera ko gukwirakwiza grafite nodule bitagenzuwe mbere yo kubitunganya, cyangwa kubera ko guhangayikishwa no guterwa no guterwa ibisigazwa byavunitse bore mugihe cyamagare.
Impamvu Ibyuma Byuma Bisaba Kurenza Gutera-Cyangwa Gukora Imashini
Ibyuma bikozwe mubyuma bisobanutse neza - nk'amazu ya piston pompe ya pompe cyangwa inzu ya shitingi ya shitingi - iba ku masangano ya metallurgie na geometrie. Icyuma cyumucanga cyumucanga (ASTM A536 Icyiciro cya 65-45-12) gitanga imbaraga zingana nubushobozi bwo kugabanya. Ariko nkibishushanyo mbonera ntibishobora gufata ± 0,025 mm kwihanganira imyanya kubinyamakuru. Aho niho guhuza vertical bihinduka kutaganirwaho. Ku kigo cyacu i Qingdao, icyuma kibisi gisuka mu musenyi umwe umwe, hanyuma ikindi gihe, abo bakinnyi bahura n’ingutu, CNC ihinduka, hanyuma bakarangiza gusya ku mashini 5-axis hamwe na Renishaw. Nta ntoki. Nta guhuza ibice. Nta gukeka kubyerekeranye no kwagura ubushyuhe bwa coefficients murwego rwintambwe.
Twapimye ingaruka: ibice byakozwe mumasaha 72 nyuma yo gukina byerekana 40% munsi yo kugoreka nyuma yo gutunganywa kuruta ibyakozwe mububiko bwibyumweru bibiri. Kubera iki? Kuberako tugenzura gukonjesha gukonje kuva gusuka kugeza kuri anneal - kandi dukora imashini mbere yicyiciro cya kabiri imvura igwa mumaganya yimbere. Ibyo ntabwo ari ibitekerezo. Namakuru yinjiye mumasoko 1200+ atangira kuva 2019.
Igiciro nyacyo cyabatanga ibyuma "Bisanzwe"
Abaguzi bamwe bafata ibyuma nkibisahani byibicuruzwa - urwego rwo gutumiza, kubona icyemezo, komeza. Ariko mugihe umubiri wawe wumuvuduko wumuvuduko ugomba gufunga kuri 250 ° C mugihe urwanya ruswa ya H₂S, ASTM A536 ntabwo ihagije. Ukeneye gukurikiranwa kugeza kuri chimie yamashanyarazi: karubone ihwanye (CE) hagati ya 4.2-4.5, sulfure <0.015%, na nodularity>85% byemejwe binyuze muri ASTM E2352 metallography - ntabwo ari utubari twinshi.
Twakomotse ku cuma cyemewe cyemewe kuva ISO 9001 zashizweho hamwe na ladle-to-casting traceability. Ubushyuhe bwose buzana raporo ya spekrometrike n'amashusho ya microstructure. Niba umukiriya abajije "AMS 5387 icyuma kibangikanye," ntidusimbuza-turasobanura impamvu amavuta ya cobalt-nikel ari muri nozzles no mumacomeka, mugihe icyuma cyinshi-nodularity ductile icyuma kiri munzu zikorera imitwaro. Icyitonderwa ntabwo kijyanye no kwihanganira gukomera wenyine. Nibijyanye no guhuza imyitwarire yibintu na fiziki ikora.
Ibibaho Mubyukuri Imbere-Uruganda rukora imashini ikora ibyuma
Genda unyuze mu iduka ryacu, urahabona ibintu bitatu bihujwe byakazi bikora muburyo bubangikanye:
- Kwitegura: Kwigana ibishushanyo (ukoresheje MAGMASOFT®) byemeza igishushanyo mbonera mbere yo gusuka bwa mbere - ntakindi gikonje gikonje mumfatiro ya pompe yoroheje.
- Kugenzura imashini: Buri Okuma MULTUS U3000 ikora G-code yemejwe na STEP AP242; igikoresho kwambara indishyi buri bice 12 ukoresheje murwego rwo gupima laser.
- Igenzura: Ibipimo byose byingenzi bigenzurwa inshuro eshatu-ubanza hamwe na CMM, icya kabiri hamwe na optique igereranya, icya gatatu hamwe na gage ikora igereranya inteko nyayo.
Nta ntambwe yasimbutse. Nta "ubugenzuzi bwa nyuma" ni kashe ya reberi. Mugihe umukiriya yohereje ibishushanyo bya GD & T biremereye kubikoresho bya injeniyeri yimashini, injeniyeri zacu zerekana ibishobora kugongana * mbere yo kuvuga - atari nyuma yo guca ibice.
Guhitamo Mugenzi wawe Ntabwo ari Geografiya-Byerekeranye na nyirubwite
Amajyaruguru ya OEM yo muri Amerika y'Amajyaruguru akeka ko guta hanze bisobanura gutinda kwa NRE cyangwa kuvura ubushyuhe budahuye. Ariko umwanya wigihe ntacyo bivuze ugereranije na tekiniki. Dukoresha injeniyeri ya buri munsi mucyongereza, icyesipanyoli, n’ikidage - dukoresheje moderi ya MBD isanganywe hamwe nigihe nyacyo. Iyo uruganda rukora hydraulics rwiburayi rukeneye imibiri ya ISO 13849 yujuje ubuziranenge, twateje imbere urwego rwo kugabanya imihangayiko hamwe nitsinda ryibikoresho byabo - kandi dutanga ibyangombwa bya PPAP Urwego rwa 3 muminsi 11.
Ibyo birashoboka kuko ibyacu uruganda rukora ibyuma ntabwo itanga metallurgie, kuvura ubushyuhe, cyangwa ubugenzuzi bwa nyuma. Dufite igikoresho cyuzuye - kuva chimie yashongeshejwe kugeza gushika hejuru ya Ra ≤0.8 µm kumaso. Kandi byose turabyandika: ibikoresho bifatika, ibiti bivura ubushyuhe, raporo ya CMM, ndetse na pH ikonje ya pH yo gukora imirongo ikora T800-alloy ibice byegeranye.
Niba umushinga wawe utaha usaba ibyuma bisigara 10 000 byikurikiranya kuri 200 MPa yo guhura - cyangwa niba ukomeje kujya impaka niba ugomba kubanza guta imashini cyangwa imashini - tangira ukoresheje imyitwarire yibintu, ntabwo ari kataloge y'abacuruzi. Ubusobanuro butangirira aho icyuma gikomera. Ibindi byose birakurikira.
