Apo mainjiniya anotsanangura high precision magnesium alloy die casting fekitori, havasi kungokumbira mutengesi-vari kuda kugadzikana pasi pemabhasikoro ekupisa, kufanana kwe microstructural pazvikamu zvakatetepa-zvakakomberedzwa, uye zero kukanganiswa pakusimba kwesimba pakupisa kwesevhisi yakakwirira. Magnesium alloys akaita seAZ91D, AM60B, uye WE43 inopa isingaenzaniswi simba-ku-huremu reshiyo-asi chete kana iyo yekukanda kufa ichitonga hydrogen porosity, inoderedza kufa soldering, uye kukiya mu ± 0.05 mm kushivirira pazvinhu zvidiki se 0.8 mm kukora kwemadziro. Iyo nhanho yekutonga haiitike mune generic foundries.
Takakanda pamusoro pe12,000 WE43 magnesium dzimba dzeaerospace hydraulic actuators-uye batch yega yega yakapfuura 100% X-ray yekuongorora pasina kuderera kwepasi. Sei? Nekuti chaiyo magnesium kufa kukanda hakusi kwemakina akakura kana kukurumidza kutenderera nguva. Zviri pamusoro pekugadzirisa tembiricha yekunyunguduka mukati me ± 3 ° C, kuchengetedza kufa kwepamusoro kupera pazasi peRa 0.4 μm, uye kushandisa vacuum-inobatsirwa kuzadza kudzvanyirira oxide firimu entrapment. KuQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tinobata magnesium kwete se "aluminium yakareruka," asi sesimbi inoshanda, ine nzara yeokisijeni inoda midziyo yakatsaurirwa, inert-gasi inodzivirira, uye chaiyo-nguva mhango kudzvanywa kwekutarisa.
Mazhinji magnesium anofa kukanda kutadza kunotevera kumashure kune matatu anogona kudzivirirwa: kusawirirana kukwenenzverwa kwezviyo panguva yekusimba, kusingadzoreki intermetallic chikamu kugovera (kunyanya Mg.17Al12), uye post-casting kukanganisa kubva kusara kwekunetseka kuzorora. Isu tinovhara iwo mapundu nekubatanidza yekukandira simulation neicho chaiyo-mukufa thermocouple mepu-tichibva tasimbisa yega mold geometry inopesana neASTM B94-22 tensile mabara uye ISO 11992-2 kuvuza-chiyero kuyedzwa. Yedu jecha-yakakanda magnesium prototypes inowana Cpk ≥ 1.67 pane yakakosha GD&T callouts; kugadzirwa kunomhanya kunobata ± 0.03 mm pane coaxiality pakati pekubereka mabhora uye anokwira maflange-pasina yechipiri machining.
Kubatanidza kwakatwasuka kunoita mutsauko. Nepo akawanda anonzi "chaiyo" mafekitori ekunze kwekupisa kupisa kana CNC kupedzisa, isu tinodzora yakazara cheni: magnesium alloy inonyungudika mumagirafu crucibles pasi peSF.6/CO2 kuvhara gasi, high-vacuum die casting pa720-740 ° C melt temp, T6 solution annealing ine controlled ramp rates, uye yekupedzisira CMM verification uchishandisa Zeiss CONTURA G2 ine tactile scanning. Izvi zvinobvisa zvikanganiso zvechimiro-hapana zvisizvo datums pakati pekuwana uye muchina shopu, hapana yakavanzika yemafuta nhoroondo inokanganisa machinability. Apo pombi yeEurope OEM yaida magnesium cylinder housings ine 0.1 mm flatness pachiso che 220 mm uye 300 MPa simba regoho, takaendesa zvinyorwa zvekutanga mumazuva gumi nemasere - kwete nokuti takamhanyira, asi nokuti mepu yedu yepurogiramu yakanga ine zero handoff kunonoka.
Kuita kwepasirese chaiko kunonyanya kukosha kupfuura mashizha chaiwo. Mumwe mutengi akashuma 40% yehupenyu hurefu hwesevhisi pamagnesium winch centre shaft rollers maringe nearuminiyamu yakaenzana-mushure me12,000 kutenderera pasi pe85 kN radial load uye salt-spray exposure. Sei? Yedu AMS 5387-inoenderana cobalt-nickel inoiswa yakasungirirwa mune magnesium housings inochengetedza kuomarara pamusoro pe42 HRC uku iyo base alloy yakatora vibration simba. Iyo hybrid dhizaini inoshanda chete kana zvikwata zvekukanda uye machina zvichigovana misangano yekuongorora yeinjiniya-uye kana kuteedzera kwezvinhu kuchibatanidza nhamba yega yega kune yayo yepakutanga ingot lot, danda rechoto, uye tensile test report. Isu hatingosangana neISO 9001:2015-isu tinobatidza AS9100-maitiro engozi yekuongorora mune yega yega magnesium chirongwa chinotangwa.
Kana uchida a high precision magnesium alloy die casting fekitori iyo inobata magnesium sechinhu chekugadzira engineering - kwete kungotsiva kuremerwa - unoda maitiro ekuranga, simbi yekuzvidavirira, uye zero kushivirira kwekufungidzira. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoburitsa iyo kuomarara mukati me hydraulic manifolds, pombi nheyo, uye mishoni-yakakosha zvikamu zvemotokari. Precision inotanga panonyungudika inosangana nefa-uye inogara yakakiyiwa mukati kusvika yaongororwa kwekupedzisira.
