Xa iinjineli zicacisa i-Alloy 400 yendlu ebalulekileyo yevalve ye-hydraulic okanye i-high-wear piston pump component, abakhethi nje izinto eziphathekayo-bazimisele ukuzinza kwe-dimensional, ukuxhathisa ukubola kwiindawo ezityebileyo ze-chloride, kunye nokuqikelelwa kobuchule phantsi kokunyamezela kwe-GD & T. Oko kuzibophelela kubambe kuphela ukuba ingxubevange 400 inxalenye umzi-mveliso ukuhambisa icandelo kuye kwafakazela amava kunye ne-alloy's quirks: ukuthambekela kokuqina komsebenzi, ukulinganiselwa kwe-thermal conductivity, kunye novakalelo loxinzelelo olushiyekileyo ngexesha lonyango lokushisa.
Sibone iiprojekthi ezininzi kakhulu zimile-hayi ukusuka kwiziphene zoyilo, kodwa kubuchule bokwenza obungafanelekanga. Umthengi wake wasithumelela umzobo we-Alloy 400 umzimba wokunceda uxinzelelo kunye ne-± 0.01 mm yokwenyani kwizibuko ezisibhozo ze-M12. Umthengisi wangaphambili usebenzise iindlela zesixhobo ezisemgangathweni kunye nokuqukuqela kokupholisa okuqhelekileyo. Isiphumo? Iindawo ezintathu ezilahliweyo, i-micro-cracks kufuphi neengcambu zentambo, kunye nokulibaziseka kweeveki ezimbini. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sisebenza ngomatshini kwaloo nxalenye inye sisebenzisa i-low-RPM, izicwangciso ze-spindle high-torque, inkungu yomoya ye-cryogenic endaweni ye-coolant yesikhukula, kunye nokugqiba ngokulandelelana kokugqiba kwi-setup efanayo-ukugcina ukuphazamiseka kwe-thermal ngaphantsi kwe-0.005 mm. Ayiyothiyori leyo. Oko kukwenza yonke imihla.
Ukuchaneka Akongezwanga-Yakhelwe kwiNdlela yeNkqubo
I-alloy 400 ayisiyonto "yomatshini kunye nenqanawa". Ukusebenza kwayo kuxhomekeke kwindlela ukuphosa, ukwenziwa, kunye nokugqiba ukusebenzisana. Asikhupheli naliphi na inyathelo. Indawo yethu ehambelana ne-ISO ijongana nokuphosa utyalo-mali kwiijometri zangaphakathi ezintsonkothileyo-ezifana nezindlu zempompo ze-cylinder ezinamatshaneli okupholisa adibeneyo-emva koko uguqukela ngokuthe ngqo kwi-5-axis CNC machining usebenzisa izixhobo ze-carbide ezinemiphetho ene-nano-coated eyenzelwe ngokukodwa i-nickel-copper alloys. Akukho handoffs. Akukho mahluko kwibhetshi ukuya kwibhetshi kulungiso. Akukho kubanjwa kwakhona okwazisa impazamo eyongezelekayo.
Oku kudityaniswa ngokuthe nkqo kuzisa iingenelo ezintathu eziphathekayo:
- Ulawulo lweMicrostructure: Siqinisekisa ulwakhiwo lwenkozo oluphoswe kusetyenziswa i-metallography ngaphambi kokuba kuqale ukusebenza-sakha nasiphi na iqashiso esibonisa ulwahlulo lwe-dendritic, nokuba amandla okuqina adibana ne-spec.
- Inkumbulo yomgangatho: Ii-CMM zethu ziqhuba uhlolo olupheleleyo lwe-ASME B89.1.12M emva komsebenzi ngamnye-kungekhona nje ekugqibeleni. Silandelela i-thermal drift kwiishifti kwaye sibuyekeze iindlela zesixhobo ngexesha lokwenyani.
- Isiqinisekiso sengqibelelo engaphezulu: Kumacandelo afana ne-winch center shaft rollers, silinganisa uburhabaxa bomphezulu (Ra) *kunye* nobunzulu bobunzulu beplastiki engaphantsi komhlaba—hayi nje emva komatshini, kodwa emva koxinzelelo lokugqibela lonyango lobushushu.
Kutheni "isiko" sithetha ngaphezulu kweJiyometri engeyiyo eMigangatho
Ezinye iivenkile zizibiza ngokuba “zesiko” kuba zamkela imizobo yePDF. Imveliso yesiko lokwenyani iqala kwangethuba-ngorhwebo lokhetho lwezinto eziphathekayo akukho datha ityhilayo. I-alloy 400 isebenza kakuhle emanzini olwandle, ewe-kodwa kuthekani ukuba isicelo sakho siphinde sijikeleze phakathi kwe--40 ° C yokuqalisa kunye ne-120 ° C yokusebenza kweqondo lokushisa? Standard annealed Alloy 400 unako embrittle. Sisebenzisana nabanikezeli abaqinisekisiweyo ukuvelisa ibha ye-ASTM B164 ye-mill-annealed kunye ne-tighter intergranular corrosion test (IGC) indlela yokupasa (i-IGC) kunye nokuqinisekisa ubushushu bonke ngovavanyo lwe-ASTM G28A ngaphambi kokusika.
Siphinde sisombulule iingxabano ezingabonakaliyo ephepheni. Umzekelo: Ipompo ye-OEM yaseYurophu ichaze i-Alloy 400 yokudibanisa umlomo kodwa ifune i-Ra ≤ 0.4 µm kwizitulo zangaphakathi ezi-conical. Ukusila okusemgangathweni kushiya amanqaku encoko; ukupholisha kususa iileya ezibalulekileyo eziqinileyo. Isisombululo sethu? I-Hybrid electrochemical machining (ECM) yokususa isambuku, ilandelwa yi-orbital diamond honing kunye nengxelo ye-real-time surface metrology. Ixesha lomjikelo lonyuke nge-18%, kodwa isivuno sokuphumelela kuqala sixhume ukusuka kuma-62% ukuya kuma-99.3%. Leyo yindleko yesiko elisebenzayo-hayi isiko lokuthambisa.
Ukulandeleka onokuthi ukuphicothe-hayi nje ibango
"Ukulandelelwa ngokupheleleyo" akuthethi nto ngaphandle kokuba unokuvula ingxelo kwaye ubone: inani elinyibilikayo elichanekileyo lebar ekrwada, uhlaziyo lwenkqubo ye-CNC esetyenziswa kwi-axis nganye, isatifikethi sokulinganisa i-CMM probe sifakwe istampu kwiiyure ze-4 zokulinganisa, kunye ne-ID yomsebenzisi osayine ekuhlolweni okubonakalayo phantsi kwe-200-lux ukukhanya kunye ne-10 × ukukhulisa. Sizinzise oku kwi-ERP yethu-kungekhona njengebhokisi yokuthobela, kodwa njengesixhobo sokusombulula ingxaki. Xa umthengi echaza ukuvuza kwe-gasket kwangaphambi kwexesha kwivalve yoxinzelelo, sitsale iwele ledijithali lalo nxalenye, izixhobo zokunxiba ezinqamlezayo, kwaye safumana utshintsho olulodwa lokufaka ngaphandle kobomi obucetyiswayo. Sayitshintsha-kwaye songeza umkhondo wobomi besixhobo esizenzekelayo kuzo zonke iinkqubo ze-Alloy 400.
Olu qeqesho luyakhula. Nokuba ufuna iprototype enye okanye iziqwenga ezingama-500 ngekota nganye, inxalenye nganye ye-Alloy 400 iphethe ileyibhile enekhowudi ye-QR enxibelelanisa nedosi yedijithali epheleleyo: iicerti zezinto eziphathekayo, iirekhodi zokuhlola, iigophe zonyango lobushushu, kunye neelogi ze-pH ezipholileyo ezivela kwiseli yomatshini.
Ukukhetha i ingxubevange 400 inxalenye umzi-mveliso ayikokufumana eyona sicatshulwa sisezantsi-imalunga nokuchonga iqabane elinenkqubo engqongqo ihambelana nendima ebalulekileyo yecandelo lakho. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke i-Alloy 400 odolo njengenkontileka ye-metallurgical: ukuhambisa ukuchaneka kwe-dimensional, ukulondoloza imfezeko ye-microstructural, kunye nesiqinisekiso sokusebenza okusebenzayo-kungekhona nje ephepheni, kodwa endle. Kuba xa inkqubo yakho iqhuba kwibar ye-300 kwiimeko ezingaselunxwemeni, izitaki zokunyamezelana azixoxisani. Nathi asikwenzi oko.
