Xa iinjineli zichaza utyalo-mali lokuphosa umzi-mveliso waseChina iinkonzo ze-high-pressure hydraulic valves okanye i-cobalt-alloy pump parts, azigcini nje isinyithi-ziqinisekisa ukuzinza kwe-dimensional phantsi kwemithwalo ye-300-bar, ukunyaniseka kwe-microstructure emva kokunyanga ubushushu, kunye nokulandelwa kwebhetshi epheleleyo ukuya kwinani elinyibilikayo. Leyo sisiseko-hayi ngaphandle.
Siye sabona iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba izindlu zokuphosa azikwazanga ukubamba ± 0.05 mm kwi-AMS 5387 cobalt alloy nozzle bore-okanye okubi nakakhulu, kuhanjiswe inxalenye ye-alloy ye-T800 "eqinisekisiweyo" kunye nokuhamba okuziinkozo okungahambelaniyo kwindawo enzima yoxinzelelo. Oyena nobangela? Izakhono eziqhekekileyo. Ivenkile eyomeleleyo ekugalweni kwesanti ihlala ingenasakhono se-CNC esine-multi-axis ukwenzela ukuba i-contouring yokugqibela. Umntu onesakhono kubuchwephesha be-superalloy akafane alawule ukwakhiwa kweqokobhe lotyalo-mali okanye iprofayile yendlela yendlela yokuthambisa echaza ukugqitywa komphezulu kunye nobunzulu bangaphakathi.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isombulula oku ngokudibanisa iindlela ezintathu ezidityanisiweyo ngokuqinileyo: ukuphosa utyalo-mali oluchanekileyo, ukuchaneka okuphezulu kwe-CNC machining, kunye nokugqitywa kwe-metallurgically eqinisekisiwe-konke phantsi kophahla olulodwa oluhambelana ne-ISO eQingdao. Akukho handoffs. Akukho zithuba zojongano. Akukho zijikelo zokuphinda zenziwe kwakhona ezibangelwa kukukhukuliseka okuphakathi phakathi kokucutheka kokucutha kunye nokunyamezelana kwasemva komatshini. Inkqubo yabo iqala ngezinto eziqinisekisiweyo zezinto eziluhlaza-i-AMS 5387 i-cobalt-nickel alloy billets efunyenwe kubaboneleli abaphicothiweyo, iqinisekiswe xa ifunyenwe isebenzisa i-OES spectroscopy kunye novavanyo lwe-tensile nge-ASTM E8. Iqashiso ngalinye liphethe amaxwebhu apheleleyo eekhemikhali kunye neepropathi zoomatshini, ezibotshelelwe ngokuthe ngqo kwicandelo eligqityiweyo ngeekhowudi ze-ID ezifakwe ngelaser.
Umgca wabo wokuphosa utyalo-mali uphatha iijiyometri ezintsonkothileyo ukuba umatshini oqhelekileyo wodwa awukwazi ukufikelela kuqoqosho-okanye konke. Cinga ngezindlu zepiston pump cylinder ezineepaseji zokupholisa ezidityanisiweyo, imizimba yevalve yoxinzelelo eneendlwana ezibhorekileyo, okanye iirola zeshaft yewinch eneejenali ezineasymmetric kunye neendlela zangaphakathi. Ezi ayizonxalenye eziphoswe-kwaye zilityalwe. Nganye ilawulwa yi-dewaxing, ukudutyulwa kweqokobhe leceramic ngokuchanekileyo, ukugalelwa kwe-vacuum, kunye nokuqiniswa okucothayo okupholileyo ukunciphisa uxinzelelo olushiyekileyo. Emva koko kuza i-different real: in-house 5-axis CNC machining ngokukhawuleza emva kokunyanga ubushushu, usebenzisa ii-CMM ezilinganisiweyo kunye neeprofilometers ze-optical ukuqinisekisa i-callouts ye-GD & T-kuquka indawo yokwenyani, i-cylindricity, kunye nobunzima bomhlaba Ra ≤ 0.8 μm apho ukutywinwa okusebenzayo kuxhomekeke kuyo.
- Ubuchule bezinto eziphathekayo ngaphaya kweenkcukacha zedatha: Abagcini nje "ukusebenzisa" i-cobalt alloys-bayayiqonda indlela i-T800's carbide precipitation behavitation itshintsha ngayo ngesantya sokupholisa, kutheni i-AMS 5387's hardness eshushu iyancipha ngaphezu kwe-850 ° C ngexesha lokunciphisa uxinzelelo, kunye nendlela yokulungelelanisa ubukhulu begobolondo kunye nobushushu be-preheat ukukhusela i-micro-shrinkage kwi-12-mm yodonga lwama-nozzles.
- Akukho "standard" ukugqiba ukuyekelela: Ukunyaniseka komphezulu ayisiyonto icingelwayo. Iiparamitha zokudubula zilungelelaniswe ngokwenxalenye yejometri kunye nemo yokulayisha. I-Passivation ye-casts stainless steel castings ilandela i-ASTM A967, kunye novavanyo lwe-sulfate yethusi yokufunyanwa kwentsimbi yamahhala-kungekhona nje ukuhlolwa okubonakalayo.
- Uyilo-lokwenziwa-kwakhiwe ngaphakathi: Xa abathengi bethumela imizobo enokunyamezelwa okuqinileyo kwiimpawu ezinodonga olucekethekileyo, iinjineli zabo ziba semngciphekweni kwangoko-hayi ngamanqaku afanayo afana “nokuba nzima,” kodwa ngezinye iindlela ezithile: “Yehlisa ubukhulu bodonga ukusuka kwi-2.3 mm ukuya ku-≥3.0 mm ukunqanda ukugqwetheka kweqokobhe ngexesha lokuthotywa,” okanye “Shift idatum B ukuya kumphezulu womatshini endaweni yokungaqinisekanga kolu phawu.”
Abanye banokuxoxa ukuba ukuphosa ngaphandle konxweme kwazisa umngcipheko wekhonkco lokubonelela. Kodwa ekusebenzeni, umngcipheko omkhulu ulele ekukhetheni umthengisi ngaphandle kokudibanisa ngokuthe nkqo. Silandelele ukuhanjiswa kwentsebenzo kwii-odolo ze-47 kwiinyanga ze-18: i-98.3% ngexesha lokugqitywa kwe-middle-volume runs (50-500 pcs), kunye nokuthunyelwa kade kweqanda okubangelwa kukuthintelwa kwenkqubo yangaphakathi. Ngoba? Ngenxa yokuba ukuphosa, umatshini, kunye ne-QA zisebenza kwiishedyuli zokuvelisa ekwabelwana ngazo-kungekhona iikhalenda zesebe ezihlukeneyo. Xa umthengi efuna ukuqinisekiswa okungxamisekileyo kweskimu se-GD & T elungisiweyo, ukuguqulwa kokuhlaziywa komdwebo kuphantsi kweeyure ze-48-kungekhona iiveki ezimbini.
Oku akukho malunga nexabiso eliphantsi. Imalunga neziphumo eziqikelelwayo. Indlu yevalve yoxinzelelo eyenziwe apha iphila kwimijikelo engama-20,000 kwibhari engama-280 ngaphandle kokuqhekeka kokudinwa ngenxa yokuba iqokobhe lotyalo-mali lilawula ukuqina kolwalathiso-kunye noomatshini be-post-cast bagcina uxinzelelo olucinezelayo kwi-bore surface. Iplagi ye-cobalt alloy itywina ngokuthembekileyo kwi-450 ° C ngenxa yokuba i-coefficients yokwandisa i-thermal ifaniswe kuyo yonke indibano-kungekhona nje ukuqikelelwa kumaxabiso eencwadi. Ezi ziphumo zivela ekwenzeni izinto ezimbalwa, kodwa ukuzenza ngokuphindaphindwa okubhaliweyo, ukuqina kwesinyithi, kunye nokunyamezelwa kwe-zero kwimveliso esekwe kuqikelelo.
Kwiinjineli ezichaza iindawo apho ukusilela kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho—utyalo-mali lokuphosa umzi-mveliso waseChina kufuneka ithethe ngaphezu kwejografi. Kuthetha ukulawula. Ukulandeleka. Kwaye ukuzithemba ukuba xa udibaniso lwakho lwempompo lungena kwi-Intanethi, ukuphosa akuzange kuthululwe nje-yenziwe ukuba ibekho.
