Kana mainjiniya ataura simbi isina simbi yemavharuvhu akasimba ehydraulic kana mavharuvhu asingapfeki mawinji, kashoma kugadzikana pamagiredhi akaitwa. Vanoda microstructural consistency, padhuze-net-shape kuoma, uye dimensional kugadzikana pasi pemhepo inopisa bhasikoro-mamiriro apo kugadzirwa kwechinyakare kana machining kunodonha. Ndicho chikonzero zvikwata zvakawanda zvekugadzira zviri kutendeukira upfu metallurgy simbi isina tsvina-kwete seimwe niche imwe nzira, asi seyokutanga mhinduro yemishini-yakakosha chaizvo zvikamu. Uye imwe nzvimbo inogara ichipa vimbiso iyoyo QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Powder Metallurgy Stainless Simbi: Iko Precision Inosangana NeMetallurgical Control
Takaona vatengi vachidzoka katatu nevharuvhu imwechete yekudhirowa kwedzimba-kutanga yakagadzirwa kubva kubhawa stock, ndokuzoisa mari-yakakandwa, pakupedzisira poda metallurgy (PM) simbi isina tsvina. Kudzokororwa kwega kwega kwakagadzirisa dambudziko rimwe asi kwakaunza rimwe: kugadzira kwakasiya kushushikana muzvikamu zvitete-madziro; kukanda kwakaunza porosity pamatanho ekuyerera-nzira; PM akaunza zvese density> 99.5% uye kufanana kwezviyo mukati me 0.05 mm kukora kwemadziro. Musiyano waive usiri kuita chete - kwaive kudzokororwa kwe500-unit batch pasina kufanirwa.
PM simbi isina tsvina haina sintered 316L uye inonzi yaitwa. Inotanga negasi-atomized pre-alloyed powders-kazhinji 17-4PH, 15-5PH, kana tsika Cr-Ni-Mo-Cu zvakasiyana-yakaongororwa kusvika ± 5 µm particle distribution. PaQINGDAO QIANGSENYUAN, compaction inoshandisa kaviri-acting press ine real-time density monitoring, kwete fixed tonnage. Sintering inoitika muvacuum furnaces ine controlled dow point (<-40 ° C) uye ramp rates ≤5 ° C / min kudzivirira chromium carbide kunaya. Zvakaguma nei? Chinhu chine simba regoho 20-30% yakakwira kupfuura yakaenzana magiredhi, zero yemukati voids inoonekwa ne ultrasonic test pa 10 MHz, uye kushata kwepamusoro Ra ≤1.6 µm as-sintered-hapana kugaya kwechipiri kunodiwa kune vasiri-chisimbiso nzvimbo.
Nei “Fekitari” Ichikosha Kupfuura “Mutengesi”
Vamwe vatengesi outsource sintering. Vamwe vanobata machining ekupedzisira chete. A chokwadi upfu metallurgy Stainless simbi fekitari ndiye muridzi wecheni yakazara-kubva pairisiti yehupfu kusvika kune inoshanda bvunzo-uye QINGDAO QIANGSENYUAN inoita izvo chaizvo. Nzvimbo yavo yeQingdao inobatanidza ISO 9001-yakasimbiswa PM mitsetse ine 5-axis CNC maseru, mahovhoni ekupisa anoiswa kuAMS 2750E, uye CMM-akashongedzerwa metrology labs anomhanyisa Zeiss CONTURA G2 masisitimu.
Iyi vertical control inobvisa maviri akajairwa kukundikana mapoinzi: Chekutanga, zvinhu traceability. Batch yega yega inotakura maMTR akazara-kwete chete dhata rekusimba, asi okisijeni/nitrogen yakasara, mishumo yekuongorora sieve, uye sintering atmosphere logs. Chechipiri, geometric kutendeka. Kana mutengi akakumbira piston pombi silinda yeimba ine 8 radial inotonhorera madoko, ± 0.01 mm kushivirira kwenzvimbo, uye yakaomeswa nzvimbo dzekuisa chisimbiso, timu yakagadziridza iyo yegirinhi chikamu chejometry, sinter shrinkage muripo wemepu, uye post-sinter kupisa-kubata kukanganisa kururamisa-zvese zvisati zvachekwa kucheka.
Zvishandiso Chaiyo, Kwete Chete Catalog Nhamba
Tarisa kunze kwezvinyorwa. Mukutumira chaiko, yavo PM isimbi inogadzirisa matambudziko chaiwo emunda:
- Oiri & gasi downhole mavharuvhu: AMS 5387 cobalt-chromium alloy nozzles inomira 120 ° C H₂S nharaunda ichichengetedza chigaro chemukati mushure me50,000 kumanikidzwa kutenderera-yakasimbiswa kuburikidza neAPI RP 14D hydrostatic endurance bvunzo.
- Injiniya mota winch centre shafts: T800-yakavakirwa PM zvikamu zvinomhanya 3 × kureba kupfuura zvakaumbwa zvakaenzana mumunyu-spray yakakurumidza kupfeka miedzo, nekuda kweuniform carbide dispersion inobvisa yakasarudzika nzira dzekupfeka.
- High-speed pombi impellers: Net-shape sintered 17-4PH dzimba dzinoderedza nguva yegungano ne 65% maringe nemabhaudhi akawanda-zvidimbu madhizaini, pasina gasket inodonha pa450 bar differential pressure.
Aya haasi mabhenefiti edzidziso. Iwo mhedzisiro yakasimbiswa kuburikidza nevatengi-run munda maodhisheni-kwete lab simulations chete.
Izvo Injiniya Chaizvo Zvinoda Kuziva Asati Ataura
Zvinhu zvitatu zvinoshanda zvinoumba zvakabudirira PM mapurojekiti asina tsvina:
- Dhizaini yekutanga sintering: Undercuts yakadzika kupfuura 3 × madziro ukobvu inoda yechipiri machining. Minimum radius ndeye 0.2 mm-kwete 0.05 mm seEDM. Isu tinopa zano rekutanga GD&T ongororo tichishandisa yavo yemahara engineering yekutsigira sevhisi.
- Batch size economics inochinja pa250 units: Pazasi pazvo, kushandisa amortization kunoita kuti PM idhure kupfuura CNC. Pamusoro payo, mutengo wakamhara unodonha 18-22% nekuda kwe70% kushoma kwemarara emarara uye 40% mapfupi ekutungamira nguva.
- Kupedzisa kwepamusoro hakusi sarudzo-inoshanda: As-sintered surfaces inosangana neISO 13715 yenzvimbo dzisiri dzakakosha, asi zviso zvekuisa chisimbiso zvinogara zvichiitwa vibratory finish + electropolishing kuRa ≤0.4 µm. Hapana kunze.
Ivo havasundidzire PM paisiri yake-senge mabhuraketi makuru ezvimiro kana dzimba dzakadzikira. Tarisiro yavo inoramba yakamanikana: yepamusoro-inoshanda chaiyo zvikamu uko density, corrosion resistance, uye dimensional kugadzikana zvinosangana.
Kutarisa Mberi: Kubva kuFactory kuenda kuFoundry-Machining Hybrid Partner
Muganhu unotevera haungori nani PM isina tsvina - ndeye hybrid kugadzira. QINGDAO QIANGSENYUAN ikozvino yave kukodzera maitiro akasanganiswa: kunyudza muviri wevharuvhu padyo, wobva waita localized laser cladding yeStellite 6 panzvimbo yekuisa chisimbiso, ichiteverwa nekupedza-kutendeuka mune imwe CNC setup. Izvi zvinobvisa kusawirirana kwemafuta pakati pechigadziko uye pamusoro pezvinhu zvakafukidzwa - chikonzero chinozivikanwa chekukurumidza kuparara mumashandisirwo epamusoro-soro.
Kune mainjiniya anoongorora vatengesi, bvunza mibvunzo mitatu: Vanogona here kukuratidza sintering mamiriro ematanda eodha yako yekupedzisira? Vanoita-in-process density cheki-kwete chete chikamu chekupedzisira chekuongorora? Uye vachabatana here nekugadzira yako GD&T stack-up isati yatanga kudzvanya? Kana mhinduro iri hongu kune vese vatatu, uri kushanda ne upfu metallurgy Stainless simbi fekitari-kwete chete mumwe mutengesi. Musiyano iwoyo unotsanangura kuvimbika kana kuita kusingagone kukanganisika.
