Iyo sisitemu ya hydraulic yananiwe munsi yumuvuduko wa bar-350, nyirabayazana ni gake pompe-ni igice cya homogenizing valve. Twabibonye inshuro eshatu muri uyu mwaka wonyine: gutembera kudahuye, guturika k'umuriro nyuma yinzinguzingo 420, isuri yintebe itaragera muri cobalt-alloy nozzles. Buri kunanirwa kwagarutse kumpamvu imwe -ihame ridahagije murwego rwo hejuru rushyushye T800 ibice. Niyo mpamvu abajenjeri bashakisha Homogenizing Valve igice cyuruganda abafatanyabikorwa ntibabaza “Urashobora kubikora?” Barabaza bati "Urashobora gufata mm 0,015 mm kuri bore ya mm 220 mugihe ukomeje ubuziranenge bwa microstructure ya AMS 5387 ukoresheje kugabanuka kwa nyuma?"
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. asubiza icyo kibazo hamwe na disipuline - ntabwo ari amasezerano. Isosiyete ikorera i Qingdao, isosiyete ikora ikigo cyujuje ISO aho gukina, gutunganya CNC, no kurangiza bitaba intoki zikurikiranye - ni ibyiciro bihujwe murwego rumwe rukurikirana. Iyo umukiriya atanze igishushanyo cya GD & T kiremereye kumazu ya piston pompe ya pisitori, injeniyeri ntibagenzura gusa kwihanganira. Bagereranya inzira yo kugoreka ubushyuhe, kwemeza umucanga wumucanga urwanya urukuta rwuburebure bwurukuta, kandi mbere yo kugenzura ingaruka zo kugongana kubikoresho kumashini 5-axis-mbere yo guca icyuma cya mbere.
Ibintu bitatu bya tekiniki bitandukanya ibi Homogenizing Valve igice cyuruganda uhereye kubatanga-intego rusange:
- Cobalt-nikel alloy ubuhanga ntabwo ari theoretical-ni kalibibasi. Ibice bya AMS 5387 bikorerwa ubushyuhe bubiri (igisubizo cya anneal kuri 1175 ° C + gusaza kuri 845 ° C), hamwe nubushyuhe bwo mu itanura bwashyizwe kuri ± 1.2 ° C hejuru ya 1.8 m³. Buri cyiciro kibona igenzura-nta “cyemezo gifatika gifatwa.”
- Kugenzura ibipimo bitangira mbere yo gutunganya. Ibyuma bikozwe mu bishingwe bya pompe bifashisha sisitemu igenzura-gukonjesha riser igabanya imihangayiko isigara kuri 38% ugereranije no kwinjirira bisanzwe - bipimwa hakoreshejwe itandukaniro rya X-ray ku ngero ntangarugero, ntabwo byagereranijwe.
- Ubusugire bwubuso buhuye nibisabwa bikora. Intebe ya homogenizing intebe ntabwo ikenera Ra 0.4 µm ahantu hose-ikenera Ra 0.2 µm kumurongo wa kashe, Ra 1.6 µm kumurongo wa firimu, hamwe no kugenzura imbaraga zisigaye (−320 MPa) muburebure bwa mm 0.15. Ibyo bigerwaho hamwe no kurangiza kuvanga: gusya neza bikurikirwa no kurasa ingufu nkeya kurasa, kugenzurwa hamwe na Almen imirongo hamwe na SEM yambukiranya.
Bamwe bashobora kuvuga ko kwishyira hamwe kwa offshore-imashini itumira itumanaho ryitumanaho cyangwa icyuho cyinyandiko. Ariko mubikorwa, twakurikiranye ibicuruzwa 17 bya prototype muri Amerika ya ruguru no ku masoko y’ubumwe bw’ibihugu by’Uburayi - kandi buri suzuma ry’ubuhanga ryarimo kugabana igihe nyacyo cyo gusangira raporo za CMM zuzuye kuri moderi ya CAD, hamwe na tangazo rya GD&T ryahamagaye igihe. Oya "tuzabisobanura nyuma." Oya “uko tubyumva.” Gusa kwemeza bizima: "Uku gutandukana kwa mm 0,02 kugwa hanze yibitekerezo byawe-dore ikarita yubushyuhe yerekana impamvu, kandi dore igishushanyo mbonera cyavuguruwe kugirango tuyikosore."
Kwishura byerekana mumikorere yumurima. Umukiriya umwe wo mu majyepfo yuburasirazuba bwa Aziya yasimbuye umurambo wa valve umurage wananiwe kumasaha 14,000 yo gukora hamwe na Q8ANGSENYUAN ya T800 alloy verisiyo. Nyuma yamasaha 28.500 - munsi ya 290 ° C ikomeza, 310-yumurimo - ibice byatsinze igenzura rya ultrasonic hamwe nubutaka bwa zeru. Ntabwo ari “ugikora.” Byagenzuwe neza. Ukwo kwizerwa guturuka ku guhuza guhagaritse: itsinda rimwe rihitamo ingobo ya cobalt, igatera ubusa, imashini icyambu cya geometrie, kandi igakoresha nitride ya nyuma. Nta ntoki zisobanura ko nta gihindagurika cyihishe - nta gukura kw'intete kutagenzuwe mu gihe cyo kwimura ibikoresho, nta butaka bwanduye bwanditse mbere yo kubumba.
Amakipe atanga amasoko asuzuma a Homogenizing Valve igice cyuruganda, tangira ufite ibibazo bitatu: Icya mbere, barashobora kukwereka raporo y'ibizamini by'ibikoresho fatizo * kuri numero yawe yihariye * - ntabwo ari rusange? Icya kabiri, raporo zabo za CMM zirimo isuzuma ryuzuye rya GD&T (ntabwo ari "OK / NG" pass / gutsindwa)? Icya gatatu, ni ubuhe buryo bwanditse bwo gukemura ibipimo bidahuye hagati-gukora, gusiba, cyangwa kureka inganda? QINGDAO QIANGSENYUAN itangaza uko ari batatu abisabwe. Uburyo bwabo ntabwo ari ukwirinda gutsindwa. Nijyanye no kumenya inyubako muri buri cyiciro-iyo rero gutandukana kwa 0.008 mm kugaragara mubikorwa, bitera isuzuma ryihuse rya metallurgji-ntabwo ari ikibazo cyabakiriya nyuma yo koherezwa.
Urebye imbere, ikibazo ntabwo gipima umusaruro-ni ugukomeza imikorere ikora neza. Icyiciro gikurikiraho R&D yibanze kubikorwa bivangavanze: ishoramari-ryakozwe na valve umubiri hamwe nu miyoboro ikonjesha ikonje, aho kwigana ubushyuhe bitera ibishushanyo mbonera hamwe na CNC ikurikirana. Intego? Fata 0,01 mm silindrike kuri mm 300 z'umurambararo utabanje kugarura ubushyuhe. Ibyo ntabwo ari iterambere ryiyongera. Ibyo ni ugusobanura icyo "imikorere-yo hejuru" isobanura kuri homogenizing valves-micron imwe yemewe icyarimwe.
