Xa iinjineli zidinga iindawo zetsimbi ezingayi kuqhekeka phantsi kwe-300 bar, zixhathise ukugalela kwiimpompo zamanzi etyuwa, okanye zibambe i-± 0.02 mm geometry emva kokunyanga ubushushu-zitsiba ii-generic foundries. Babiza a mveliso yesanti yesiko ngamava aqinisekisiweyo kwi-cobalt alloys, izindlu zehydraulic, kunye neendawo zokunxiba ezibaluleke kakhulu. Kulapho ukuchaneka kuyeka ukuba lucaciso-kwaye ibe sisiphumo esiphindaphindwayo.
Ukuphoswa kweSanti ayiseyo "Siseko" kwakhona-Yenziwe ngobuNjineli
Abaninzi basacinga ukuba ukuphosa isanti kuthetha ukunyamezela okuphantsi, ixesha elide lokukhokela, kunye nomsebenzi wepatheni owenziwe ngesandla. Hayi apha. Kwiziko lethu elithobela i-ISO eQingdao, ukugalelwa kwesanti kudibanisa ngokuthe ngqo nomatshini we-CNC, uhlolo oluqhutywa yi-GD&T, kunye nokulandeleka kwesinyithi. Sijulela izindlu zengxubevange ye-T800 esekwe kwi-cobalt kwiimpompo zepiston-emva koko ubuso bomatshini bokutywina ukuya kwi-Ra 0.4 µm kwiseti enye. Akukho kukrwelwa ngesandla. Akukho zilophu zokuphinda zisebenze. Ulawulo lwenkqubo ebhalwe nje ukusuka ekugcwalisweni kokungunda ukuya kwingxelo yokugqibela yeCMM.
Siye sabona abathengi bengaphumeleli kathathu ngaphambi kokuba baqhagamshelane nathi-kungekhona ngenxa yokuba imizobo yabo yayingalunganga, kodwa ngenxa yokuba ababoneleli babo bangaphambili baphatha ukuchithwa kwesanti "njengendawo yokuqala," kungekhona inkqubo elawulwayo. Ukutshintsha okungundoqo? Ukungunda ngesandla? Ixesha le-shakeout elingahambelaniyo? Zonke zibangela i-porosity kufuphi neefayili zoxinzelelo oluphezulu. Isisombululo sethu: i-automated mold compaction, ii-curves zokupholisa ezilawulwayo, kunye nexesha langempela lokubeka iliso lobushushu ngexesha lokuqina. Isiphumo? I-First-pass isivuno ngaphezu kwe-92% kwi-iron castings ngaphezu kwe-80 kg-nokuba kunye neepaseji zangaphakathi ezingaphantsi kwe-6 mm.
Kutheni le nto iCobalt-Nickel Alloys ifuna ngaphezulu kuneLayisensi yeFoundry
I-cobalt alloys njenge-AMS 5387 ayinzima nje ukwenza umatshini. Abayixoleli imbali yobushushu. Ukuphambuka kwe-5 ° C ngexesha lokutshintsha ukuhanjiswa kwe-carbide. Ukwahluka kwe-2% ekunyakameni kwesanti eluhlaza kutshintshe ireyithi yokucutha nge-0.15 mm nge-100 mm. Yiyo loo nto sisebenzisana kunye nomthombo we-ingots kunye nabathengisi abaqinisekisiweyo-kwaye sivavanye ubushushu bonke bobungakanani beenkozo, umxholo wesigaba se-intermetallic, kunye nobunzima bokuphosa kwangaphambili.
Izinto zethu eziceliwe kakhulu ziyayingqina: imilomo ye-cobalt alloy ye-high-velocity slurry injection, i-AMS 5387 iinxalenye zempompo ezisebenza kwi-180 ° C yomsebenzi oqhubekayo, kunye ne-non-standard center shaft rollers kwiiwintshi zemoto yobunjineli. Ezi ayizizo iimilo zesitokhwe. Ziyi-geometries ezisebenzayo-i-tapered bores kunye ne-interference fits, i-flanges ye-asymmetric kunye nemilebe yokutywinwa koxinzelelo, i-cavities eyimfama efuna i-venting directional. Wonke umntu uqala ngokuphosa ukulinganisa (sisebenzisa i-MAGMASOFT®), hayi ukuqikelela.
Abanye banokuphikisa ukuba utyalo-mali lunika ukugqitywa okungcono komphezulu. Yinyani-kwiinxalenye ezincinci. Kodwa kwizindlu ze-cylinder ezinobunzima be-120 kg okanye iziseko zempompo ngaphezu kwe-1.5 m ubude? Ukuphoswa kwesanti kuphumelela kwiindleko, ukukala, kunye nozinzo lwe-dimensional kuwo wonke amacandelo amakhulu. Sidibanisa zombini xa kufuneka: isanti-cast-cast shape, emva koko utyalo-mali-iqokobhe lugqibe kwiindawo zokutywina ezibalulekileyo.
Udibaniso oluthe nkqo luthetha ukuba akukho zithuba zeHandoff
Izandla ezithathu zibulala ukuthembeka: ivenkile yokulahla → ivenkile yomatshini → umthengisi wobushushu → ukugqiba indlu. Ngamnye wongeza umngcipheko-ukunganxibelelani kakuhle kwiireferensi zedatum, ukugqwethwa kwe-thermal okungabhalwanga, ukungahambelani kokudubula okubukhali. Siyaziphelisa ezo zithuba.
- Iyaphosa: Isanti eluhlaza, i-resin-bonding, kunye ne-foam elahlekileyo-ekhethiweyo ngokwengxenye yomsebenzi, kungekhona
- Umatshini: I-5-axis CNC yee-contours ezinzima; uvavanyo oludityanisiweyo lwenkqubo yokuqinisekisa i-GD&T
- Ukugqiba: Ukudubula ukuchama nge-SAE AMS 2430 nganye, ukudlula kwi-ASTM A967, ii-HVOF zokugquma ukuxhathisa ukhukuliseko
- Ukulandeleka: Yonke into iphethe ikhowudi ye-QR edibanisa kwi-cert yayo yezinto, ilog yokuphosa, ijika lokuphatha ubushushu, kunye nengxelo yeCMM
Umxhasi we-oilfield yaseNyakatho yaseMelika wake wasithumela i-valve ye-valve yensimbi engaphumeleliyo-eqhekekileyo entanyeni ye-weld emva kwenkonzo yeenyanga ze-4. Uphononongo lwethu lwe-metallurgical lubonise ukukhululeka koxinzelelo lwasemva kwe-weld. Sayila ngokutsha ukuphosa ukuphelisa ijoyinti yeweld ngokupheleleyo. Isiphumo: Iinyanga ezili-14 zobomi bentsimi, ukungaphumeleli kwe-zero. Akunjalo kuphela imveliso. Yintsebenziswano yobunjineli.
Eyona nto uyifumanayo-hayi nje le nto uyithembisileyo
Awudingi omnye umthengisi othi "senza isanti yesiko." Udinga umntu ophendula le mibuzo ngaphambi kokuba ucaphule:
- Ngaba unokubamba i-0.05 mm flatness kwi-600 × 400 mm ye-sand-cast base plate-emva kokunciphisa uxinzelelo kunye nomatshini?
- Ngaba i-cobalt alloy castings yakho iyahlangabezana ne-AMS 5719 kunye neemfuno zempembelelo-njengoko kuvavanywa nge-ASTM E8 / E23 kwi-* yakho* yobushushu?
- Ngaba uya kuqinisekisa ii-engile zedrafti kunye ne-radii ukwenzela ukwenziwa-kwaye ucebise ezinye iindlela eziphucula ubomi bokudinwa ngaphandle kokutshintsha umsebenzi?
Senza njalo. Ngalo lonke ixesha. Ngenxa yokuba ukuthembeka akwakhiwa kumzobo. Yakhelwe kwindlela olawula ngayo ukulingana kwekhabhoni, ukuqina komngundo, ubushushu bokugalela, kunye nesantya sokupholisa. Yingakho ii-OEM ze-hydraulic zehlabathi jikelele, abakhi bempompo ye-offshore, kunye nabahlanganisi bezithuthi ezikhethekileyo babuyela-kungekhona ngexabiso, kodwa ngenxa yeziphumo eziqikelelwayo.
Ukuba iprojekthi yakho elandelayo ibandakanya iivalvu zoxinzelelo, izindlu zempompo zepiston, okanye amacandelo e-winch enobunjineli-kwaye ufuna mveliso yesanti yesiko ephatha i-metallurgy njengenzululwazi, kungekhona umsebenzi wezandla-usele uyazi ukuba uqale phi. Ukuchaneka kuqala apho iingqikelelo ziphela.
