Apo mainjiniya anotsanangura a tsika alloy machining factory, havasi kungoodha zvikamu-vari kuchengetedza kudzikama pasi pe350 bar hydraulic pressure, kuramba galling mucobalt-alloy nozzles pa650°C, kana kuvimbisa microstructure kuenderera mberi kwejecha-cast pombi yekugara iyo inomhanya maawa 20,000 pasina kukundikana. Ndicho chokwadi chekushanda-kwete vimbiso yedatabase.
Isu takaona vatengi vachiendesa madhirowa eAMS 5387 cobalt alloy pombi zvikamu kuti vagamuchire zvikamu zvine subsurface porosity mushure mekupisa kupisa. Vamwe vanofungidzira kuti "CNC machined" zvinoreva "kugadzirira kuisa" -kusvikira T800 alloy centre shaft roller yavo yatadza kuyedza vibration nekuda kwekusadzoreka kwasara kushushikana kubva kune asymmetric milling pass. Idzi hadzisi nyaya dzekupedzisira. Ndiwo mhedzisiro yakananga yekugona kwakakamukana: kukanda kunoitwa nechitoro chimwe, hutsinye hwekugadzira neimwe, kupedza kukuya nechetatu - imwe neimwe iine nzira dzakasiyana dzematurusi, manejimendi ekupisa, uye maitiro ekuongorora.
Nei kusanganisirwa kwakamira kusiri kwesarudzo kune yakakwira-alloy chaiyo basa
Kudzora kwechokwadi kunotanga chip yekutanga isati yabhururuka. PaQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mbishi zvinhu certification haisi danho rekunyora-ndiyo hwaro. Yese coil yeT800 cobalt-based alloy inosvika neguyo bvunzo mishumo inoteedzerwa kune kupisa nhamba, kemikari inosimbiswa neASTM E1086, uye saizi yezviyo yakasimbiswa kuburikidza neASTM E112. Isu hatigamuchire "yakajairika" chemistry. Isu tinoda yakasimbiswa AMS 5387 kutevedzera-kunyanya kune yakakosha pombi zvikamu uko chromium musiyano uri pamusoro pe ± 0.3% inokonzeresa nguva isati yakwana intergranular corrosion munzvimbo dzakavava gasi.
Kuranga uku kunoenderera mberi nekuita. Kukandira jecha uye kukanda mari kunoitika panzvimbo-kwete kunze-saka tinodzora mold preheat rates, solidification gradients, uye shakeout nguva. Kutsauka kwe2°C mutembiricha yekuumbwa kunoshandura dendrite ruoko spacing ne12%, zvichikanganisa machinability uye hupenyu hwekuneta mudzimba dzepiston pombi silinda. Maseru edu eCNC anobva ashandisa-in-process CMM verification mushure mekuomesera, semi-kupedza, uye kupedza kupfuura-kwete kungoongorora kwekupedzisira. Isu tinoyera kunyura kwemafuta pamichina yakawanda-axis maminetsi makumi mapfumbamwe ega ega nekuti kuwedzera kwe 0.008 mm mukuchinja kwedzimba dzespindle kwakabereka concentricity kupfuura nzvimbo dzekushivirira dzeGD&T.
Iko uko kwakajairwa machining workflows inoputsika-uye izvo chaizvo zvinoshanda
Vamwe vanogona kupokana kuti chero ISO 9001-yakasimbiswa shopu inogona kubata cobalt-nickel alloys kana ikapihwa chaiyo yekushandisa. Asi chiitiko chenyika chaiyo chinotaurira imwe nyaya. Carbide yakajairwa inoisa kutyoka ipapo ipapo paAMS 5387 pamatengo ekudya ari pamusoro pe0.05 mm/rev. Isu tinoshandisa PCD-tipped maturusi ane negative rake geometry, inotonhorera inounzwa pa 120 bar kuburikidza nemukati spindle chiteshi, uye adaptive maturusi nzira dzinochengetedza nguva dzose chip load-kunyangwe yakatenderedza 3D contours senge pressure valve miviri ine 4.2 mm madziro makubvu uye 0.025 mm flatness zvinodiwa.
Kutendeseka kwepamusoro kunokosha senge geometry. Girazi-kupedzisa Ra 0.2 µm haizodzivise kushushikana kwegora kutsemuka kana subsurface microcracks iripo kubva mukusarudzika vhiri rekugaya. Kukandira simbi isina tsvina inoshandiswa mumabhesi epombi ekumahombekombe, tinoshandisa electropolishing * mushure * kupfurwa kudongorera — kwete zvisati zvaitika — kuchengetedza kudzvanya kwasara kushushikana uku tichiwana corrosion resistance paASTM A967. Kutevedzana uku hakusi dzidziso. Iyo inosimbiswa pane chaiyo mijenya yekugadzira, ine muchinjiko-chikamu SEM ongororo inosimbisa kusavapo kwechena-layer kuumbwa.
Izvo "tsika" zvinonyatso rehwa mumishoni-yakakosha maapplication
Tsika haisi yezvisina-standard dimensions chete. Zviri pamusoro pekugadzirisa kwekushanda. Kana European OEM yaida winch centre shaft rollers yearctic-class engineering mota, ivo vakatsanangura kuomarara-asi havana kuverengera kuderera-tembiricha kukanganisa kuoma. Takamhanya bvunzo dzeCharpy V-notch pa -40 ° C pane matatu akasiyana-achipisa, akakurudzira yakagadziridzwa kudziya kutenderera, uye akaunza rollers ane 42 J simba rekuita (kwete chete inodiwa 27 J). Sarudzo iyoyo yakadzivirira kutsemuka kwe brittle panguva yekudzoserwa kwakaerekana kwemutoro panzvimbo yakafukidzwa neaizi.
Iyi nhanho yekubatana inoenderera kune dhizaini-ye-kugadzirwa. Isu tinosimudzira macallouts eGD&T anopokana nemakona ekukanda. Isu tinotevedzera kushatisa kwemafuta mune dzakatetepa-yakavakirwa cobalt alloy nozzles panguva yemhinduro annealing. Isu tinopa mhinduro yekugadzira mukati meawa 48-kwete mavhiki-nekuti prototype inonokedza kuitika mundima yekusimbisa nguva. Mamaneja edu ezvirongwa anotaura zvakanaka ASME Y14.5, kwete Chirungu chete.
Kana uchida a tsika alloy machining factory iyo inobata simbi seinjiniya-kwete kutenga-uri kutsvaga kubatana kwakasimba pakati pezvinhu zvesainzi, kugadzirwa kwemafuta, uye kunyatso fambisa kudzora. Iwe unoda yakanyorwa traceability kubva kunhamba yekupisa kusvika kune yekupedzisira yekuongorora report. Unoda shamwari dzakagadzirisa T800 alloy plug seating torque curves pane gumi nematanhatu hydraulic system akasiyana. Iwe unoda kuurayiwa kwakasimbiswa-kwete chete zvirevo zvekugona. Ndiyo chikumbaridzo panopera kutsanangurwa uye kuita kunotanga.
