Imvura igabanya ubukana bwinganda zicyuma zidasaba ibirenze ubumenyi-metallurgiki-bisaba kugenzura byimazeyo imyitwarire yibintu, ituze ryimiterere, hamwe nubwizerwe bwimikorere mugihe gikabije cya serivisi. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twakoze ibice birenga 12.000 byuzuye mubikoresho bya PH bitagira umuyonga - harimo 17-4PH, 15-5PH, hamwe n’icyiciro cyahinduwe na AMS 5659 - kumibiri ya hydraulic valve, amazu ya pompe yumuvuduko mwinshi, hamwe na shitingi ya winch. Ikitandukanya igisubizo gifatika no kunanirwa guhenze ntabwo ari uguhitamo ibinyobwa byonyine - nuburyo bwo guta ubunyangamugayo, gusubiramo ubushyuhe, hamwe no gutunganya imashini nyinshi zihuza urwego.
Ni ukubera iki ibisanzwe bya PH bitagira ibyuma byananirana munsi yumutwaro wisi
Twabonye uburyo butatu bwo gutsindwa muburyo butangwa nabakiriya batanzwe na PH ibice bitagira umwanda: microcracking nyuma yo gusaza, ubukana budahuye mubice byurukuta ruto, hamwe no gutembera imburagihe mu kuzenguruka. Ibi ntabwo ari inenge yibintu-ni icyuho cyibikorwa. Kurugero, pompe imwe yu Burayi OEM yatangaje 22% ibisakuzo muri 17-4PH ya silinderi mugihe cyo gusaza kwa H900. Isesengura ryacu-nyirabayazana ryerekanye itanura ritaringaniye mu ziko ryabo - bitera ± 8 ° C ubushyuhe bwumuriro hejuru yumutwaro. Twabikosoye duhinduranya na vacuum-ifasha gusaza hamwe nigihe nyacyo cyo gushushanya mapping kuri fixture. Igisubizo: gutandukana gukomera kuva kuri ± 12 HRC kugeza kuri ± 3 HRC; umusaruro wateye imbere uva kuri 71% ugera kuri 98.4%.
Ubunararibonye bwatwigishije isomo rikomeye: gukomera kwimvura ntabwo ari "gushiraho-kwibagirwa" kuvura ubushyuhe. Ni uruhererekane rukomatanyije - ubushyuhe bwa annealing ubushyuhe bugomba gufata muri ± 5 ° C, igipimo cyo kuzimya kigomba kurenga 50 ° C / sec kugirango uhagarike imiterere ya delta-ferrite, kandi igihe cyo gusaza / ubushyuhe kigomba guhuza neza nicyiciro cyimvura (urugero, cluster ikungahaye kuri Cu kuri 17-4PH na Ni₃Ti kuri Custom 465). Gutandukana niminota 10 kuri 480 ° C, hanyuma utamba 15-20% imbaraga zingutu nta mpinduka zigaragara.
Uburyo Vertical Kwishyira hamwe ikemura ikibazo cya PH Stainless Steel Ikibazo
Abatanga ibicuruzwa benshi basohora casting, kuvura ubushyuhe, hamwe no gutunganya - buri ntambwe yongeyeho gucikamo ibice no kugabanuka. Twese uko ari batatu murugo, munsi ya ISO 9001: 2015 igisenge cyemewe muri Qingdao. Mugihe umukiriya wa peteroli yo muri Amerika ya ruguru yari akeneye inkoni ya piston 15-5PH ifite silindrike ≤0.02mm hejuru yuburebure bwa 450mm, itsinda ryacu ryateraga umucanga ryakoresheje ibishushanyo mbonera bya ZrO₂ kugirango tugere ku buso bwa Ra 3.2μm - kugabanya ibicuruzwa byakuweho nyuma ya 40%. Hanyuma ikigo cyacu cya CNC cyakoresheje inzira zijyanye no guhuza n'imihindagurikire y'ikirere zishyura uburyo bwo kugabanuka kwaho bwagaragaye hakoreshejwe imashini ya CMM mbere yo gukora. Ubwanyuma, selile yacu ivura ubushyuhe ishaje buri gice hamwe nigiti cya termocouple - gishobora gukurikiranwa numubare wibikoresho fatizo hamwe nindangamuntu yizuba.
Ntabwo aribwo buryo bwo kwishyira hamwe. Ni igenzura ripima:
- Ibikoresho bikurikirana kuva ingot icyemezo kugeza igice cyarangije raporo
- Kugereranya ibipimo bifata ≤0.015mm mubice 100 bigize ibice 100
- Ubusaza bukomeye busanzwe gutandukana kuva 4.7 HRC bugera kuri 1.3 HRC
- Kurangiza isura yabitswe kuri Ra 0.4 mm kuri kashe ikomeye
Aho PH idafite ibyuma ihura ninshingano-Imikorere ikomeye
Abakiriya ntibagura ibyuma bya PH bitagira umwanda-bagura ibintu bitarimo umuvuduko ukabije, igisubizo cya zeru-inkoni, cyangwa ubuzima bwa shaft irwanya umunaniro. Niyo mpamvu dushyiramo kwemeza imikorere muri buri cyiciro. Kuri AMS 5387 cobalt-alloy nozzle ihujwe na 17-4PH igenda ya flange, ntitugenzura gusa chimie nimbaraga zikomeye. Dukoresha amagare 500 yumuzingi hagati ya –40 ° C na + 180 ° C, hanyuma tugenzura microseparation intera interineti dukoresheje ultrasonic C-scan. Turagerageza kashe mumaso munsi yumutwaro wimikorere - ntabwo ari ubushyuhe bwibidukikije gusa. Kandi kuri winch center shaft rollers, twemeza gukomera kwa torsional kurwanya imiterere ya torque ya profil yinjiye kuva mubice bifatika.
Iyi lens ikora ihindura byose. Umukiriya yigeze gusaba "bisanzwe 17-4PH" kuri valve yo kwigunga. Isuzuma ryacu ryubuhanga ryerekanye ko ubushyuhe bwa H1025 butazarokoka cyikubita hasi muri metero 3.000 zubujyakuzimu. Twasabye ko hahindurwa umusaza wikubye kabiri (1025 ° F × 4h → ikirere gikonje → 900 ° F × 4h) cyongereye ubukana bwavunitse 37% mugihe tugumana> 1200 MPa UTS. Bemeje impinduka-kandi bongera intera yo kubungabunga kuva kumezi 18 kugeza 36.
Guhitamo Imvura Yaguye Gukomera Umufatanyabikorwa Wuruganda
Niba porogaramu yawe irimo umuvuduko wamagare, amazi yumunyu, cyangwa kwambara, kuzenguruka ibyuma bya PH birashobora kuba amahitamo yawe akomeye - ariko mugihe umufatanyabikorwa wawe akora uruganda rwuzuye. Baza ibi bibazo mbere yo gusinya PO:
- Urashobora kunyereka impapuro zo kuvura ubushyuhe kumpapuro eshatu ziheruka za 17-4PH, harimo imyanya ya thermocouple nigipimo cya ramp?
- Waba ukora progaramu ya CMM igenzura nyuma yo gukomera - hanyuma ugahindura inzira zikoreshwa?
- Ni ubuhe butumwa bukomeye cyane butandukanye hagati ya 15-5PH casting ipima> 80 kg?
- Nigute ushobora kwemeza kurwanya ruswa kubiteranya bya PH bitagira inteko?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. asubiza ibyo bibazo hamwe namakuru - ntabwo ari udutabo. Dutangaza buri gihembwe raporo yimikorere ya metallurgical kumiryango ya PH idafite umwanda kurubuga rwacu rwa tekiniki. Dutanga impamyabumenyi ihuriweho hamwe kugirango yemeze ingingo ya mbere. Kandi dufatanya gutegura gahunda yo kugenzura ihujwe na ASME BPVC Igice cya VIII, API 6A, cyangwa ISO 15156 - icyaricyo cyose kijyanye na sisitemu.
Ejo hazaza h'imvura ikomera ubushobozi bwuruganda rukora ibyuma ntabwo ruri mu ziko rinini cyangwa izunguruka ryihuse - ahubwo ni ibitekerezo byimbitse hagati yubushake, kugenzura microstructure, hamwe nimikorere yumurima. Aho niho twibanda. Nibyo bitanga ibice bidahuye gusa na spes-ariko birenze.
