Iyo abajenjeri bagaragaje ibyuma bikozwe muri hydraulic manifolds, amazu ya pompe, cyangwa imashini ya winch shaft, ntabwo bagura ibyuma gusa-bagura ituze ryikigereranyo munsi yumuvuduko wa bar-300, guhuza microstructural guhuza ibice 500, hamwe no kutihanganira na gato kwihanganira uturere twikoreye imitwaro. Niyo mpamvu “uruganda rukora ibyuma"Ntabwo ari icyiciro cyabacuruzi-ni urwego rwimikorere.
Twabonye imishinga myinshi yatinze gushingwa ifata ibyuma nkibikorwa byibicuruzwa: grafite nodule ibara yirengagijwe, amafaranga yo kugabanuka akekwa kuva kumurage, gahunda yo kuvura ubushyuhe ikoreshwa muri rusange. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Gutera ibyuma byose bitangirana nubushake bwa metallurgjiya - ntabwo ari ukuzuza gusa. Ikigo cyacu cyujuje ISO muri Qingdao gikora gahunda yo guta umucanga uhindurwamo ASTM A48 Icyiciro cya 35, A536 ibyuma byangiza, hamwe na ferritic-pearlitike ivanze-buri kimwe cyatoranijwe kugirango gihuze imyirondoro ikora, ntabwo ari imbonerahamwe yerekana imbaraga.
Ibisabwa-byukuri birahindura gahunda yacu. Kububiko bwa pisitori ya piston pompe, tugenzura igipimo cyo gukonja muri ± 2 ° C hakurya yumubyimba kugirango twirinde kugoreka guhuza bore. Kubikoresho byubwubatsi winch center shaft rollers, twemeza morfologiya ya grafite dukoresheje SEM mbere yo kuyitunganya - kuko gukwirakwiza flake bigira ingaruka kumibereho yumunaniro mugihe cyigihe 12,000. Kandi iyo abakiriya bohereje GD&T guhamagara nka ⌀0.015 mm kwihanganira imyanya kuri 8 × Ø22 mm, ntidupima gusa-twigana kwaguka k'ubushyuhe mugihe cyo gutunganya, hanyuma duhindure ibikoresho bya offsets mugihe nyacyo dukoresheje Renishaw QC20-W. Nuburyo dufata umwanya wukuri muri 0.008 mm kuri tombora.
Kwishyira hamwe bihagaritse bituma ibi bishoboka-kandi birakenewe. Gutera, gutunganya CNC, no kurangiza bibaho munsi yinzu. Nta ntoki zisobanura ko nta gutandukanya ibipimo hagati yo kugabanuka no kurangiza. Turashiraho imashini itaziguye nkuko byashobotse, ikuraho amakosa yo kongera guhuza. Kuvura ubushyuhe bikurikira gukata nta gutinda kwimura ibintu - nibyingenzi kugirango ugere kuri Brinell ikomeye (220-260 HBW) mubice byinshi. Kandi kubera ko dukura ibikoresho fatizo byemewe-bikurikiranwa na raporo y'ibizamini byo gusya - tuzi neza ibirimo sulfure muri buri cyiciro mbere yo gusuka. Amazi meza hejuru ya 0.025%? Yanze. Ntabwo ari ukubera kurenga kuri spec - ariko kubera ko ishobora kugabanya micro-kugabanuka mu masangano hagati y'ibice bito kandi binini.
Itandukaniro ryacu rikomeye ntabwo ari ibikoresho-ni kuvuga neza. Iyo umushoramari wa peteroli yo muri Amerika ya ruguru yari akeneye AMS 5387 cobalt alloy pompe ibice byahinduwe bikozwe mubyuma byangirika kubikoresho byoroheje, ntabwo twahinduye ibikoresho gusa. Twagereranije umukino wo gusiganwa ku magare muri ANSYS, duhindura imiti ya nodularisation kugirango tugumane uburebure bwa 18% kuri -20 ° C, kandi twemejwe no kurwanya imyenda yo kurwanya isuri ya API RP 14E. Igisubizo: 40% igiciro cyigiciro cyo hasi, gutsindwa kwa zeru mumezi 18. Ngiyo itandukaniro hagati yo guta ibyuma nubuhanga bwicyuma.
Niba urimo gusuzuma a uruganda rukora ibyuma, baza ibibazo bitatu: Bashobora kukwereka raporo ya CMM iherutse kubice hamwe na dat5 zingenzi? Zigumana ibintu byose byuzuye - harimo na chimie ya chimie ya ladle - kuri buri cyiciro? Kandi itsinda ryabo ryubwubatsi rizashyira ahagaragara GD&T amakimbirane * mbere yo gusubiramo - atari nyuma yo kugenzura ingingo ya mbere? TEKINOLOGIYA YA QINGDAO QIANGSENYUAN irasubiza yego-buri gihe. Kuberako kwizerwa bitatanzwe mubikoresho byoherezwa. Yubatswe muri buri gusuka, buri cyerekezo cyubushyuhe, buri micrometero yimashini igenzurwa.
