Guhitamo uburenganzira igice ntabwo ari ugutora amagambo ahendutse. Nibijyanye no guhuza imyitwarire ya metallurgjiya, gutuza kurwego, no kugenzura inzira kumaganya nyayo-umuvuduko mwinshi, gusiganwa ku magare yumuriro, kwambara nabi. Twabonye amazu menshi ya hydraulic pompe yamenetse kuri 3000 psi kuko kwihanganira guta umucanga ntibyari byemewe kurwanya umuhamagaro wa GD&T. Abandi bananiwe kwipimisha imikorere nyuma yo kuvura ubushyuhe - ntibiturutse ku guhitamo nabi, ariko igipimo cyo gukonjesha kidahuye hejuru yu mwobo. Gukora neza no gukoresha neza ibiciro ntibirushanwa. Barahurira mugihe cyo gushushanya, gutoranya ibikoresho, no gutunganya imashini ikora nka sisitemu imwe.
Tangira Inzira Yumutwaro - Ntabwo Igishushanyo
Ubunyangamugayo buri hejuru igice itangira nuburyo imbaraga zinyuramo. Inzu ya piston ya pompe ya piston ntabwo ifata amazi gusa - yohereza umuriro, ikubiyemo imizigo ya radiyo iva mu nteko zizunguruka, kandi ikarwanya imbaraga za axial mugihe cyumuvuduko. Ibyo bihindura byose: gukwirakwiza uburebure bwurukuta, gushyira riser, kwinjiza geometrie. Twigeze gushushanya umubiri wa cobalt-alloy valve kumpande ya peteroli ya pompe duhindura irembo rikuru kuva hejuru kuruhande. Igisubizo? Kurandura microporosity mu gice gikomeye cyo gufunga urutugu-hanyuma ugabanye ibisigazwa nyuma yimashini kuva kuri 18% kugeza kuri 2,3%. Kubera iki? Kuberako ibyuma byatembaga bisa ninzira yumutwaro, ntabwo bihabanye.
Ibi ntabwo ari theoretical. Bisobanura kwerekana igice ntarengwa cy'ubugari * kuri zone ikora *, ntabwo kuri buri gice. Bisobanura gusubiramo imbonerahamwe ntabwo ari ukurekura ibicuruzwa byonyine - ahubwo ni uburyo bigira ingaruka ku guhangayikishwa no kwikorera ibintu. Kandi bivuze gufata amafaranga yo kugabanuka ntabwo ari ijanisha ryagenwe, ariko nkimpinduka ihujwe nigihe cyaho cyo gukomera hamwe na alloy density gradient.
Guhitamo Ibikoresho ni Icyemezo Cyibikorwa - Ntabwo ari urupapuro rwihariye
AMS 5387 cobalt alloy ntabwo "nziza" kuruta icyuma cyangiza. Nigisubizo cyukuri gusa mugihe cyawe igice igomba kugumana imbaraga zumusaruro uri hejuru ya 650 ° C * kandi * ikarwanya guhagarika sulfide kumeneka mubidukikije bya gaze. Ariko icyo kivunge kimwe gisaba kugenzura neza ububobere buke mu guta umucanga - kandi butangiza imyenda ikomeye iyo ikozwe neza itabanje gukonjesha neza no guhitamo icyiciro cya karbide.
Turakurikirana ibintu bitatu bidasubirwaho kuri buri cyemezo gifatika:
- Gukurikirana neza subira kuri numero yubushyuhe na raporo yikizamini cyemewe - ntabwo "yubahiriza ASTM A487"
- Kwemeza Microstructure ukoresheje ibice byambukiranya uduce twa zone zikomeye (urugero, ingano yintete mugutwara ubuso bwa winch center shaft rollers)
- Kugenzura nyuma yubushyuhe-bwo kuvura ukoresheje ikarita ishushanya ibice bigoye, ntabwo ari ingingo imwe gusa ya Rockwell
Mugihe umukiriya wu Burayi yari akeneye ibyuma bidafite ingese kubishingwe bya pompe yamazi yo mu nyanja, twakoze ibigereranyo bigereranywa mubice bitanu bitandukanye - nubwo bose bahuye na ASTM A743 Grade CF8M. Icyiciro kimwe cyerekanaga uburebure bwa 12% mugihe cyo kuruhuka kubera igipimo gito cya Mn / Si. Icyo cyiciro nticyigeze kiva hasi.
Kwishyira hamwe Gukubita Handoff - Igihe cyose
Gutandukanya casting na mashini bitera ibiciro byihishe: kongera gukora flash idashobora kugerwaho, ibice byavanyweho bitewe nubutaka butamenyekanye, gutinda kubitanga bivuye muri protocole yubugenzuzi idahwitse. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ibikoresho byo gutunganya CNC byateguwe * mugihe cyiterambere * ntabwo ari nyuma yo gukina. Porogaramu zacu za CMM zakira amakuru ya scan ya 3D uhereye kumyatsi-umucanga * mbere yo gusuka bwa mbere. Kubera iki? Guhanura aho ihinduka ryibanze rizasunika ibipimo bivuye kwihanganira - no guhindura imashini ikora neza.
Uku guhuza guhuza gutanga ibisubizo byapimwe:
- Iterambere rinini ryiyongereyeho 40% kumibiri ya valve isaba kwihanganira mm 0.025 mm
- Ubuso bwo kurangiza bwuzuye bwazamutse kuva Ra 3.2 µm kugeza kuri Ra 1,6 µm kuri cobalt-alloy nozzle bores - nta gusya kwa kabiri
- Kugabanya igihe cyo kugabanya iminsi 11–17 kubicuruzwa bito bito, byagenzuwe mumishinga 42 muri 2023
Bisobanura kandi kwanga ibishushanyo "byiza bihagije". Mugihe umukiriya wa Amerika ya ruguru yatwoherereje imbonerahamwe ya GD&T hamwe na datum idasobanutse yerekana amazu ya pompe ya T800 ya T800, twasubije verisiyo yashyizwe ahagaragara yerekana neza ibintu bizagenda byiyongera mugihe cyo kwaguka k'ubushyuhe - maze dusaba ubundi buryo bubiri bwa datum bushyigikiwe nibisubizo bya FEA.
Ikiguzi Cyiza Kubaho Mubisobanuro Ugenzura
Ikiguzi nyacyo gitangira mbere yuko urwego rwa mbere rusukwa. Ni uguhitamo gushora imari hejuru yumucanga kumashanyarazi mato mato ya cobalt-alloy-atari ukubera ko ari "mwiza,", ariko kubera ko ikuraho amasaha 3.5 yo guterura intoki kuri buri gice kandi bikagabanya igihe cyo kugenzura cya nyuma 60%. Irimo kwerekana ZrO₂ ishingiye kuri ceramic shell binders ya AMS 5387 kugirango wirinde kwinjiza sodium iterwa no kwangirika mugihe cyo kwangiza. Irimo ikora imibare igenzura ubushyuhe bwubushyuhe * hamwe nubushuhe bwibidukikije - ntabwo bishonga gusa.
Dupima ikiguzi ntabwo kiri mumadorari ku kilo, ariko mubiciro byose kubice byujuje ibisabwa byatanzwe. Ibyo birimo:
- Igipimo cyibisigisigi biterwa no guta inenge (porosity, gufunga imbeho, inclusitions)
- Igice cya kabiri cyibikorwa byongeweho kubera guhuza geometrie
- Amasaha yubwubatsi yamaze gukemura ibibazo bidahuye hagati yo gukina no gutunganya ibyiciro
- Ibikoresho byo kugura ibicuruzwa bisimbuza ikirere nyuma yo gutsindwa kwumurima
Ku bakiriya ba tekinike yo mu majyepfo y’iburasirazuba bwa Aziya yimodoka ya winch shaft, guhinduranya kuva icyuma gisanzwe cyumuhondo ugahinduka icyuma cyahinduwe na EN-GJS-600-3 ibyuma byangiza-bigahuzwa no gukonjesha no kugabanya imihangayiko-byagabanije ubuzima bwo kubaho ubuzima bwa 37% nubwo igiciro cya 22% cyo hejuru.
Imikorere-yo hejuru igice gukora bisaba ibirenze ibikoresho byubatswe cyangwa insyo za CNC. Irasaba abajenjeri bafashe hydraulic yamenetse mumaboko yabo saa mbiri za mugitondo hanyuma bagakurikirana kunanirwa kugaruka kubishushanyo mbonera. Irasaba metallurgiste bazi uburyo karbide ya vanadium yitwara muri T800 alloy mugihe cyo guhinduka gukomeye. Irasaba sisitemu nziza ifata buri genzura nkibisubizo byatanzwe - ntabwo ari umunyezamu. Igihe kizaza ni icy'abafatanyabikorwa babona gukina atari intambwe yihariye, ahubwo nk'urwego rw'ifatizo rw'ibice bigize ubuzima bwuzuye - kuva mu cyuma gishongeshejwe kugeza ku nshingano zikomeye.
