Xa iinjineli zichaza umzi mveliso wokuphosa wotyalo-mali Izakhono ze-mission-critical valves hydraulic valves okanye i-high-wear pump housings, abakhangeli nje isiseko-bafuna ukuzinza kwe-dimensional phantsi kwe-200 MPa yoxinzelelo, ukuhambelana kwe-microstructure kwii-AMS 5387 ze-cobalt alloy batches, kunye ne-zero yokunyamezela kwi-porosity kwi-nozzle esekelwe kwi-T800. Leyo yinyani yokusebenza esiyibona imihla ngemihla kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.-inxalenye yomenzi wentsimbi echanekileyo apho ukuphosa utyalo-mali akuyona inkqubo enye phakathi kwabaninzi. Sisiseko samalungu angaphumeleliyo kuphela xa inkqubo isilela.
Kutheni le nto uTyalo-mali lungonelanga-kwaye yintoni na
Ababoneleli abaninzi badwelisa “utyalo-mali” kwiwebhusayithi yabo. Bambalwa abalawula ikhonkco elipheleleyo: imfezeko yepateni yewax kwi-±0.05 mm, iiprofayili zokudubula iqokobhe le-ceramic zilinganiswe ukuya ku-±3 °C, ixesha lokugalela elincediswa ngevacuum ngaphakathi kwemizuzwana eyi-0.8 yokujoliswe kuko, kunye nonyango lobushushu lwasemva kokuphoswa olugcinwe kwi-± 5 ° C kwiiyure ezi-4. Siye sabona imitsi emithathu engaphumeleliyo yenqaku lokuqala ukusuka kwimizi-mveliso ehloniphekileyo-zonke zilandelwa kukufuma okungalawulekiyo okomisa. Kwiziko lethu le-Qingdao, ibhetshi nganye iqala nge-ASTM E1951-ethobelayo yokuqinisekisa uburhabaxa bomphezulu kwiipateni eziphambili, ilandelwa yi-X-reyi ye-CT yokuskena ubungakanani beqokobhe losasazo phambi kokuba kuxoshwe. Yiyo indlela esibamba ngayo ukuguquguquka kodonga ukuya ku-≤± 0.3 mm kwi-120-mm-diameter piston pump cylinder housings-nangona xa ukuguqulwa kodonga kudibanisa kwi-4.2 mm.
Apho iCobalt Alloys ifuna ngaphezulu kunokumelana nobushushu
I-cobalt-nickel superalloys efana ne-AMS 5387 kunye ne-T800 ayinzima kumatshini-kunzima ukuqikelela *. Izinga lokuqina komsebenzi wabo linyuka nge-300% emva kwe-0.15 mm yobunzulu bokusika. Iimodeli zobomi bezixhobo eziqhelekileyo ziyawa. Isisombululo sethu? Beka kufutshane ne-net-shape geometry kunye ne-0.8-1.2 mm yesibonelelo somatshini, emva koko usebenzise izifakelo ze-CBN ze-custom-ground ezine-12 ° ii-engile zeraki kunye ne-0.03 mm ye-honed edges-iqinisekisiwe nge-SEM kulo lonke utshintsho lwesixhobo. Kwiiplagi ze-cobalt alloy ezisetyenziselwa iimpompo ze-subsea, oku kunciphisa ixesha lomjikelo nge-41% ngokuchasene ne-carbide eqhelekileyo ngelixa kwandisa ubomi besixhobo ukusuka kwi-8 ukuya kwi-27 inxalenye emphethweni. Okubaluleke kakhulu, sigcina umkhondo ogcweleyo wezinto ezibonakalayo: iqashiso ngalinye liphethe iingxelo zovavanyo lokusila, izatifikethi zokuhlalutya okubonakalayo, kunye nokuqinisekiswa kobungakanani beenkozo nge-ASTM E112. Akukho zinqanawa zebhetshi ngaphandle kobungqina obubhaliweyo bomxholo we-δ-isigaba ≤0.5%-engenakuxoxisana nokumelana nokudinwa ekulayisheni umjikelo.
Udibaniso oluthe nkqo olunikezela ngozinzo
Abanye abavelisi bakhupha ukugqiba. Abanye bakhupha unyango lobushushu. Asenzi nto kumacandelo abalulekileyo. Indawo yethu eqinisekisiweyo ye-ISO 9001 igcina amaziko omatshini e-CNC ane-5-axis ngaxeshanye contouring, vacuum furnaces kunye ± 2 °C ukufana kwimithwalo ye-1.2 m³, kunye namatanki e-electropolishing alungelelaniswe ukuya kwi-Ra ≤0.1 μm kwiziseko zempompo yentsimbi engatyiwayo. Kutheni le nto ibalulekile? Ngenxa yokuba ukuphazamiseka kwe-thermal ngexesha lokunciphisa uxinzelelo kuchaphazela ngokuthe ngqo i-GD&T callouts kwimizimba yevalvu yoxinzelelo. Xa umthengi esithumelele umzobo ochaza unyamezelo lwendawo ye-Ø0.05 mm kumazibuko amane ane-10-mm-diameter, siye saqhuba imodeli ye-thermal elinganiselweyo *phambi* kokusa—emva koko silungelelanise ukubekwa kwesinyusi kunye namazinga okupholisa ukunciphisa uxinzelelo olushiyekileyo. <120 MPa. Inqaku lokuqala liphumelele ukuhlolwa kweCMM kwi-Ø0.042 mm. Elo nqanaba lolawulo likhona kuphela xa ukuphosa, ukwenziwa, kunye nonyango lobushushu lusebenza phantsi kwenkqubo enye yomgangatho-kunye nelebhu ye-metrology ekwabelwana ngayo.
Yintoni efunwa ziinjineli zeHlabathi ngokwenyani-kwaye ufumane
IiOEM zaseMntla zaseMelika zifuna amaxwebhu eNqanaba lesi-3 lePPAP. Iifemu zaseYurophu ze-hydraulics zifuna isatifikethi se-EN 15085-2 kwiindibano ezidityanisiweyo. Iikontraka zamandla zaseMzantsi-mpuma Asia zigxininisa kuvavanyo lwesitshizi setyuwa kwi-ISO 9227 (NSS) iiyure ezili-1,000. Sidibana nazo zontathu-kungekhona njengezongezo, kodwa njengeendawo zokuhlola ezakhelwe ngaphakathi. Yonke iodolo yemveliso yotyalo-mali entsonkothileyo ibandakanya: uqinisekiso lwemathiriyeli ekrwada engenayo ngokuchasene nezatifikethi zababoneleli abaqinisekisiweyo; kwi-process CMM ihlola kwi-30%, i-60%, kunye ne-90% yemveliso; uvavanyo lokugqibela olusebenzayo (umzekelo, i-1.5 × ilinganiswe ukubamba uxinzelelo lwemizuzu ye-30 kuzo zonke iivalvu); kunye nokulandeleka okupheleleyo kwedijithali ukuya kwinani leqashiso leziko kunye ne-ID yomsebenzisi. Abathengi basixelela ukuba oku kuphelisa i-7-11 yeentsuku zokuphononongwa kobunjineli ngasemva naphambili. Omnye umakhi wempompo waseJamani unqumle ixesha lakhe elitsha lokuphehlelelwa kwemveliso ukusuka kwi-22 ukuya kwiiveki ze-13 emva kokutshintshela kwinkqubo yethu-kuba ukuqinisekiswa komzobo, ukutolika kwe-GD&T, kunye nengxelo yokwenziwa kwezinto kwenzeka kwiseshoni enye yemizuzu engama-90, hayi imisonto emithandathu ye-imeyile.
Ukuba isicelo sakho sifuna umzi mveliso wokuphosa wotyalo-mali ukuchaneka-kungekhona nje ukuphosa, kodwa kunokuqikelelwa, ukuphicothwa, ukuchaneka okuphindaphindiweyo-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inikezela apho ibaluleke kakhulu: kubomi bokudinwa kwenxalenye, ingqibelelo yetywina, kunye nokuzinza kwexesha elide. Asenzi amacandelo. Senza ukuzithemba kwintshukumo.
