Uruganda rukora ibyuma bya Martensitike - iyo nteruro yerekana ibirenze ubushobozi bwo gukora. Yerekana ihuriro ridasanzwe ryo kugenzura ibyuma, gutunganya neza, no kwemeza-kwemeza. Abatanga isoko ni bake bakora amanota ya martensitike nka 410, 420, 440C, cyangwa ibicuruzwa byahinduwe na 13Cr alloys * iherezo-kugeza * Twabonye imishinga myinshi ihagaze mugihe abafatanyabikorwa bashakisha gufata martensitike idafite "nkindi iyindi yose" - kureka kugenzura ubushyuhe, kudasoma nabi gradients, cyangwa kwirengagiza ibyiyumvo bya microstructural kubipimo bikonje.
Impamvu Martensitis Stainless isaba uruganda rwihariye - Ntabwo ari Imashini Yimashini
Ibyuma bya Martensitike bidafite imbaraga byongera imbaraga binyuze mu kuzimya no kurakara - ntabwo ari igisubizo gikomeye gikomera nka austenitis. Ibyo bivuze ko buri ntambwe nyuma yo guterwa igira ingaruka kumikorere yanyuma: igipimo cyo gukonjesha mugihe cyo gukomera gishyiraho imiterere yambere yintete; kuzimya ubukana bugena agace ka martensite; ubushyuhe bwubushyuhe bugenzura ubukana nubucuruzi bukomeye. Uruganda rusanzwe ntirushobora kwemeza HRC ihamye 52-58 HRC hejuru ya mm-120 ya diametre ya pompe ya pompe idafite pompe idafite igihe nyacyo cyo gushushanya hamwe nicyiciro cyihariye cyo gushira igihe.
Twahuye na valve yanze mubigeragezo byo murwego kuko uwabitanze yakoresheje kuzimya ikirere aho kuzimya amavuta kumubiri wa 420 ushingiye kubutabazi - bikavamo impinduka ya martensite ituzuye no gucika imburagihe munsi yikizunguruka. Undi mukiriya winch center shaft yananiwe kuri 65% yubuzima bwo gushushanya bitewe na decarburisation itamenyeshejwe hejuru yubuso - inenge itagaragara mugusuzuma amashusho ariko ibiza biterwa na stress ya torsional. Izi ntabwo arizo ngaruka. Nibisubirwamo byananiranye muburyo bwo gutunganya disipuline - ntabwo ibyemezo byonyine byonyine.
Nukuri uruganda rwa martensitike igomba gutunga ubushobozi butatu butavugwaho rumwe: kwemeza ubushyuhe bwo kuvura ubushyuhe (butari hanze), murwego rwo gutangiza metallography yo kwemeza microstructure, hamwe na CNC imashini ihinduranya ibice bikomereye leta - harimo ingamba zinzira zigabanya imihangayiko isigaye yongeye kugabanywa.
Kwishyira hamwe guhagaritse gukemura ibibazo-byukuri byububabare
Kunanirwa kwinshi bibaho kumwanya wa handoff: guta ubushyuhe, kuvura ubushyuhe kumashini, gutunganya kurangiza. Iyo buri cyiciro kibaye mubikoresho bitandukanye, drift iringaniye. Inzu ya silinderi ifite kwihanganira mm 0,3 mm irashobora kugabanuka - 0,15 mm nyuma yo kuzimya - hanyuma ugahindura mm + 0,1 mugihe cyo gufunga kurangiza. Hatariho amakuru asangiwe na metrology hamwe na CMMs hamwe, ibyo bihinduranya bucece.
Ku kigo cyacu cya Qingdao, amazu 13Cr ashora imari ava mu itanura akajya mu nganda zikora imashini - nta bwikorezi hagati y’ibigo, nta kongera guhuza. Dukoresha sisitemu imwe ya sisitemu kuva mubishushanyo mbonera binyuze mubugenzuzi bwa nyuma. Kuri AMS 5387 cobalt alloy pompe ibice, dukoresha imibare imwe ya GD&T kubikoresho byombi byerekana ibikoresho hamwe na plaque ya CNC. Ibi bivanaho kwibeshya - birakomeye mugihe uburebure bwurukuta butandukanye hagati ya mm 4.2 na mm 22.5 kumurongo umwe.
Ibi ntabwo bijyanye no korohereza. Byerekeranye no gusubiramo. OEM imwe yo mu Burayi hydraulic OEM yagabanije ingingo yambere yo kwemeza kuva ku byumweru 11 ikagera ku byumweru 3,5 nyuma yo kwimukira mu kazi kacu - kubera ko bahagaritse gukora ibishushanyo mbonera bya “mashini ishobora guhinduka” kuri buri interineti.
Ibyo abakiriya bakeneye mubyukuri - Kurenga impapuro
Abaguzi ntibategeka "martensitic stainless." Batumiza valve yumuvuduko ugomba gufunga kuri 250 ° C na 415 bar batiriwe. Cyangwa uruziga rwa winch rwanga gutoboka mumazi yinyanja mugihe rwohereza 1.850 N · m. Cyangwa umusingi wa pompe ukomeza uburinganire muri mm 0,015 mm hejuru ya mm 800 nyuma yamasaha 10,000 yo kunyeganyega.
- Gukurikirana ibikoresho kugeza kumubare wubushyuhe - ntabwo ari urusyo gusa, ahubwo amateka yuzuye yubushyuhe kuri buri kintu
- Ikarita yo gukomera - ntabwo ari igitabo kimwe cyo gusoma cya Rockwell, ahubwo ni ingingo 9 zamakuru ya grid hirya no hino
- Inkunga yo kugerageza imikorere - harimo hydrostatike yaturika kwemeza no gusiganwa ku magare umunyu kuri ASTM B117
- GD & T-izi ibitekerezo byubuhanga - gushyira ahamagarwa guhamagarwa bivuguruzanya kugerwaho-bigoye-leta irangiza
Ibi twabyize inzira igoye. Kera kare, umukiriya yerekanye Ra 0.4 µm hejuru yintebe ya 440C - atazi ko gusya gukomera 440C munsi ya Ra 0.6 µm bitera micro-gucika munsi yumukino wo gusiganwa ku magare. Itsinda ryacu ryasabye superfinish yegereye gusa kashe - kuzigama 37% mugihe cyizunguruka no kongera ubuzima bwa serivisi kuri 2,3 ×. Ubwo bwoko bwubushishozi bugaragara gusa mugihe metallurgie, gutunganya, hamwe nubuhanga bukoreshwa bicaye kumeza amwe.
Kureba imbere: Aho Precision Ihurira Kugenzura Ibiteganijwe
Imipaka ikurikira ntabwo yihanganira gusa. Ni uguhuzagurika. Turimo gushiramo thermocouples imbere yo gushushanya kugirango duhuze umuvuduko wo gukomera hamwe no gutandukanya karbide muri 420. Turimo guhuza umukono wa CNC spindle imikono hamwe na microcrack yo munsi y'ubutaka muri 440C mugihe cyo kurangiza. Iyi ntabwo ari R&D theatre - nuburyo twagabanije igipimo cyibisigazwa byigiciro cyinshi cya martensitike kuva 8.2% kugeza kuri 1.9% mumezi 18.
Niba umushinga wawe usaba martensitike idafite ibyuma ikora - ntabwo yatsinze igenzura gusa - ukeneye ibirenze kubitanga. Ukeneye umufatanyabikorwa ufata buri cyiciro cyo kuvura ubushyuhe nkikigeragezo cyagenzuwe, buri mashini itambuka nkibintu bya metallurgjique, na buri kintu cyatanzwe nkibikorwa byingenzi. Nibisobanuro byakazi bya a uruganda rwa martensitike yubatswe kubikorwa-bikomeye.
