Xa iinjineli zichaza amaqabane efektri yentsimbi yokugalela i-valve ye-hydraulic ebaluleke kakhulu okanye i-high-pressure pump housings, abathengi nje iindawo-bathenga uzinzo lwe-dimensional phantsi kwe-thermal cycling, i-microstructural consistency kwi-500-unit batches, kunye ne-zero ukunyamezela kwi-porosity kwi-flange ethwala imithwalo. Yingakho ukuchaneka akulona ibango lokuthengisa apha-yinto esisiseko.
Kutheni le nto "iMzi-mveliso yeNkonzo yeNsimbi" ithetha Ngakumbi kuneSanti + nesinyithi esinyibilikisiweyo
Umzi-mveliso wokwenyani wenkonzo yokuphosa intsimbi uphatha ifiziksi epheleleyo yokuqina: ulawulo lwenucleation ngexesha lokugalelwa, ukupholisa okwalathiso ukucinezela imingxunya ecuthekayo, kunye noxinzelelo lwasemva kokuphoswa oluthintela ukukhukuliseka kwe-GD&T ngexesha lomatshini wokugqibela. Siye sabona abathengi benqaba amaqashiso onke-kungekhona ngenxa yokuba imilinganiselo yayingaphandle kwe-spec, kodwa ngenxa yokuba ukuhamba okuziinkozo kuphazamise ubomi bokudinwa kwizindlu zepiston pump cylinder ezisebenza kwi-3,000 psi cycles. Kulapho amandla ahlula abathengisi kumaqabane.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwiziko elithobela i-ISO eQingdao apho ukuchithwa kwesanti kunye nokutyalomali akuzona iinkqubo ezizimeleyo-zilinganiswe ngokuchasene neziphumo ze-CNC zokwenza. Xa umthengi ethumela umzobo we-AMS 5387 cobalt alloy 6 inxalenye yepompo, iqela lethu lenza iimaphu zokunyanga ubushushu * phambi kokuba * uyilo lokungunda luqale. Ngoba? Ngenxa yokuba ii-alloys ezisekelwe kwi-T800 zandisa i-12% ngaphezu kwe-316 i-stainless ngexesha lokuxutywa kwesisombululo-kwaye ukuba awuyi kuhlawula kwipatheni, ingxelo yakho ye-CMM iya kubonisa ijometri egqibeleleyo ephepheni kunye nokungaphumeleli kokusebenza kwintsimi.
IZine eziNgaxoxisWayo kwi-High-Performance Steel Casting
Ayizizo zonke iintsimbi ezisindileyo kwiimeko zehlabathi lokwenyani. Nantsi into esiyiqinisekisayo-ngamaxesha onke:
- Ukulandeleka kwezinto phantsi ukuya kwinani lobushushu: Yonke ibhetshi yokuphosa insimbi engenasici ithwala iingxelo zovavanyo lokusila oluqinisekisiweyo olunamandla okuqina, ukuqina, kunye nokumelana nomhlwa kwe-intergranular nge-ASTM A957.
- Idimensional lock-in phambi kokuba machining: Silinganisa ijometri njenge-cast-cast usebenzisa i-optical 3D scanners-hayi nje i-CMM-ukubamba i-warpage ekupholiseni okungalinganiyo. Ukuba isiseko sempompo sibonisa i-0.15 mm isaphetha, silungisa ukulungiswa kwe-fixture * phambi * kokusika kokuqala.
- Ukuqinisekiswa komgangatho wentembeko: Kwimizimba yevalvu yoxinzelelo, senza uvavanyo lwe-fluorescent penetrant (PT) *kunye* kunye* ne-ultrasonic thickness mapping-hayi nje kwiindawo ezibalulekileyo, kodwa kwiindawo ezigcweleyo zokukhwelana apho uxinzelelo lwe-gasket luxhomekeke kubuninzi bezinto ezifanayo.
- Ukuqinisekiswa okusebenzayo ngaphaya kwemizobo: I-winch centre shaft roller ayijikelezi nje-kufuneka idlulise i-torque ngaphandle kwe-micro-slip. Sivavanya iiyunithi zeprototype kwiijigi zesiko eziphindaphinda ukulayisha kwangaphambili kunye nokujikeleza okujikelezayo.
Apho i-Standard Casters imisa khona, ukuchaneka kuyaqala
Abanye ababoneleli bacaphula iireyithi zefektri yokugalela intsimbi esekwe kubunzima bodwa. Oko kuyasilela xa inxalenye yakho ingumbhobho wengxubevange ye-cobalt engekho emgangathweni ene-0.05 mm ubukhulu bodonga kwi-45 ° yecandelo le-conical. Iindonga ezibhityileyo zipholile ngokukhawuleza, zibangela ukushwabana kwe-micro-shrinkage; iiflange ezishinyeneyo zicotha kakhulu, zivelisa uxinzelelo olushiyekileyo. Isisombululo sethu? Imijelo yokupholisa i-mold ecandiweyo elawulwa yi-PLC-elawulwa yi-PLC yokuhamba kwamanzi-aqinisekisiwe nge-infrared thermography ngexesha lokuthululwa kwelingo.
Sihambise ngaphezulu kwe-2,300 yentsimbi ekhethekileyo kunye nentsimbi engenasici ukusukela ngo-2019-akukho nanye efuna ukuphinda isebenze ngenxa yokungahambelani kwesinyithi. Njani? Sisebenzisana kunye nomthombo wemathiriyeli ekrwada kunye nezixhobo ezintathu zokusila eziqinisekisiweyo, siqhuba uhlalutyo lwekota lwe-spectral malunga nobushushu obungenayo, kwaye sigcina i-database ye-alloy enkulu ebonisa ukulingana kwekhabhoni kunye nesalathisi esiqikelelweyo sobuchule. Xa i-OEM yaseYurophu idinga iiyunithi ezili-120 zevalve yoxinzelelo lwensimbi engenastainless ene-≤0.02 mm yokunyamezela indawo kumazibuko anemisonto emithandathu, sasebenzisa le datha ukukhetha i-carbon low-17-4PH eyahlukileyo kunye nomxholo wesulfure ophuculweyo-ukusika ukunxiba kwesixhobo nge-40% kunye nokubamba i-GD & T ngqongqo kunokuba i-spec yabo yasekuqaleni ivunyelwe.
Ukuhanjiswa kweNyaniso, Hayi nje Imihla kwitshathi yeGantt
“Ukuhanjiswa ngexesha” akuthethi nto ukuba iiyunithi zokuqala ezili-10 ziyasilela kuvavanyo olusebenzayo. Isicwangciso sethu sokuvelisa sidibanisa amasango asemgangathweni-kungekhona nje amanyathelo. Umyalelo ngamnye udlula kwiindawo zokuhlola ezine: ukuqinisekiswa komzobo (ukwenzeka kwe-GD & T), ukukhutshwa kwezinto eziphathekayo (inombolo yobushushu engenisiweyo), kwi-process CMM scan (emva komatshini onzima), kunye nokuhlolwa kokugqibela (i-dimensional + functional + ebonakalayo). Sigcina ukulandeleka okugcweleyo kwedijithali: ukuba umthengi uphawule umcimbi, sitsala eyona nguqulelo yenkqubo ye-CNC, irekhodi lokunyanga ubushushu, kunye ne-ID yomsebenzisi kwimizuzu engama-90.
Olu qeqesho lusivumela ukuba sixhase zombini i-prototyping ekhawulezayo-ukuhambisa iindibano zoomatshini kunye nokuphosa ngeentsuku ze-18 zokusebenza-kunye nokubaleka okuphakathi komthamo ozinzileyo. Kwi-North American hydraulic system integrators, sibambe isitokhwe sokhuseleko sezindlu ze-cylinder eziqhelekileyo, ukunciphisa ixesha lokuhamba ukusuka kwiiveki ze-12 ukuya kwiiveki ze-3 ngaphandle kokunciphisa ukuqinisekiswa kwezinto.
Ukukhetha i-fektri yenkonzo yokuphosa insimbi ayikho malunga nokufumana isicatshulwa esisezantsi-kumalunga nokuphelisa izinto eziguquguqukayo ezibangela ukungaphumeleli kwintsimi. Kukwazi ukuba iplagi yakho ye-cobalt alloy ayiyi kuqhekeka phantsi komothuko we-thermal kuba isithuba sengalo ye-dendrite salinganiswa kwaye salawulwa. Ifumana isiseko sempompo kunye nokuphela komphezulu i-Ra ≤0.8 µm-kungekhona ngenxa yokuba ibonakala ilungile, kodwa ngenxa yokuba iindawo ezigudileyo zilibazisa ukukhukuliseka kwe-cavitation nge-3.2x kwinkonzo ye-abrasive fluid. Leyo yimigangatho ye-QINGDAO QIANGSENYUAN TECHNOLOGY idibana-hayi ngamaxesha athile, kodwa ngokucwangcisiweyo. Xa ukuchaneka komda kunye nokuthembeka kolwakhiwo akunakuxoxwa, qala nge-metallurgy onokuthi uyilandele, iinkqubo onokuthi uziqinisekise, kunye neziphumo onokuthi uzingqine.
