Xa iinjineli zichaza izinto zokubumba inaliti yesinyithi ye-high-pressure hydraulic valves okanye i-cobalt-alloy pump nozzles, abakhethi nje i-feedstock-babheja ukuzinza kwe-dimensional, ubomi bokudinwa, kunye nokumelana nomhlwa kwingqeqesho ye-metallurgical yomthengisi. Uninzi “lwezimveliso zokubumba inaliti yesinyithi” iziphumo zophando zikhomba kubavelisi bomgubo wegeneric. Kodwa ukusebenza kwehlabathi lokwenyani kuxhomekeke kwinto enqabileyo: iqabane elidibanisa umgubo wekhemistri, ukuziphatha kwe-sintering, kunye nokuqinisekiswa kwenxalenye esebenzayo-kungekhona nje kwilebhu, kodwa ngaphakathi kwimpompo yepiston izindlu zebhayisikile kwi-350 bar.
Kutheni Ukungaguquguquki Kwe-Feedstock Kuqhekeka—okanye Kwenza—Inxalenye yeMIM Yakho
Siye sabona uyilo lwe-AMS 5387 ye-cobalt ye-alloy nozzle efanayo lusilela isiqinisekiso kwiibhetshi ezahlukeneyo-hayi ukusuka kwiziphene zoyilo, kodwa ukusuka kutshintsho olufihlakeleyo kumxholo weoksijini kunye nokuhanjiswa kobungakanani besuntswana kwi-feedstock. Ibhetshi enye ibonise i-12% ephezulu ye-porosity emva kokuboleka; enye ibangele i-microcracking ngexesha le-HIP. Oyena nobangela? I-powder efunyenwe kwii-mills ezintathu ezihlukeneyo, nganye ineenkqubo zokuhlalutya ze-sieve ezingahambelani kunye nolawulo olungahambelaniyo lwe-oxide yomhlaba. Ukungaguquguquki okwenyani kuqala ngaphambi kokuxutywa: ukulandelelwa kwemathiriyeli ekrwada eqinisekisiweyo, iiparamitha zerhasi ezibhaliweyo, kunye neengxelo zohlalutyo lwe-batch-to-batch-hayi nje izatifikethi zohlalutyo ezigximfizwe "zihambelana ne-ASTM B243."
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ithatha imfuyo njengenkqubo eguquguqukayo, hayi into yorhwebo. Umzi-mveliso wabo wezinto zokubumba iinaliti zesinyithi awuboneleli nje ngomgubo-uqinisekisa indlela iqashiso ngalinye eliziphatha ngayo phantsi kwenkqubo yabo yokubopha, ukubophelela iiprofayili zeendlela, kunye nomoya wokuntywila. Baqhuba iitshekhi zokuxinana kwangaphambi kwe-sinter kunye nemephu yokuncipha kwe-thermal kuyo yonke into engenayo. Yingakho iindawo zabo ze-MIM ezisekelwe kwi-T800 zibamba ukunyamezela kwe-± 0.05 mm kwi-diameter ye-120 mm ngaphandle kwe-machining yesibini-kwaye kutheni abathengi babo babika ukusilela kwintsimi ye-zero kwiiplagi ze-cobalt alloy ezisebenza kwiindawo zegesi ezimuncu ngaphezu kweenyanga ze-18.
Ukusuka kwiPowder ukuya kwiValve yoxinzelelo: Apho ukuDityaniswa okuthe nkqo kuphelisa ukuqikelela
Abanye ababoneleli banikezela ngeendawo eziluhlaza ze-MIM kwizindlu zomntu wesithathu. Abanye bakhuphela ngaphandle unyango lobushushu okanye ukugaya okokugqibela. I-handoff nganye yongeza ukungaqiniseki: ukutshintsha kwe-thermal gradients, ungcoliseko lomphezulu luyangena, i-GD&T callouts iyahamba. Kwi-QINGDAO QIANGSENYUAN, iqela elifanayo elikhetha ipowder liphinda liprogram i-CNC grinders egqiba indawo yokuhlala ye-valve-kwaye isayine kwingxelo yokugqibela ye-CMM.
- Baphosa iipatheni zotyalo-mali lokuqala besebenzisa isixhobo sogwebu esilahlekileyo esilungiselelwe iijiyometri zeMIM ezinodonga olucekethekileyo
- Bantywila kwiziko le-vacuum kunye nexesha lokwenyani lokuhlola uxinzelelo lweoksijini-hayi nje iindawo zokubeka ubushushu.
- Benza imijikelo ye-HIP kunye namazinga oxinzelelo abhaliweyo kunye namaxesha okuhlala, emva koko baqinisekise ukuxinana nge-Archimedes kunye ne-microstructure nge-SEM-EDS.
- Bagqiba ukutywina okubalulekileyo ngokujika kwedayimani enenqaku elinye-hayi ukuqhushumba okurhabaxa-ukugcina ingqibelelo yomda wengqolowa.
Oku akuyothiyori. Xa impompo ye-OEM yaseYurophu idinga ukutshintshwa komatshini we-AMS 5387 womzimba wevalvu yoxinzelelo, bafuna ≤0.3% ukuguquguquka koxinzelelo kwiiyunithi ezingama-500. I-QINGDAO QIANGSENYUAN inikezele nge-0.18% ukutenxa okukhulu-kwaye ilandelele yonke into engaphandle kwindawo enye yokulinganisa ukulinganisa i-drift ebanjwe ngexesha lokuqinisekiswa kwe-thermocouple.
Oko Kuthethwa “Ukusebenza Okuphakamileyo” Ngokwenene Ekuqheliseleni
"Ukusebenza okuphezulu" kusetyenziswa kakubi. Isixhobo sinokuphumelela iimvavanyo ezinzima-kodwa lusilele kukudinwa okujikelezayo. Inokumelana nokutshizwa kwetyuwa-kodwa idle phantsi kwe-galvanic coupling kunye ne-stainless hardware. Ukusebenza kwenyani kuhlala kumxholo wosetyenziso.
Yiyo loo nto i-QINGDAO QIANGSENYUAN yomzi-mveliso wezinto zokubumba iinaliti zesinyithi ifakela iinjineli zezicelo-hayi nje ii-metallurgists-kuphononongo loyilo lwabathengi. Ababuzi ukuba "Ufuna ntoni i-alloy?" Babuza: "Yintoni eyona nto iphezulu yoxinzelelo lwe-spike inkqubo yakho ibonayo? Yintoni i-pH yamanzi ekuqaliseni? Mingaphi imijikelo ye-thermal phambi kokugcinwa?" Impendulo yabo malunga nokuveliswa kwemveliso ibandakanya izilumkiso ezinje: "Le mitha ye-0.2 mm kwi-nozzle ye-nozzle iya kubamba i-binder residue-icebisa ukunyuka ukuya kwi-0.35 mm okanye ukutshintshela kwi-solvent debinding," okanye "ukukhula kweenkozo ze-T800 ngaphezu kwe-1220 ° C kuya kunciphisa ukuxhathisa kwe-creep apha-makhe silungise iprofayili ye-sintering."
Baye bathumela ngaphezu kwe-17,000 iinxalenye ze-MIM kwi-offshore oil & gas winch center shaft rollers ukususela ngo-2021. Yonke iyunithi ithwala i-traceability epheleleyo-inombolo ye-batch, i-ID ye-sintering log, isatifikethi somjikelezo we-HIP, kunye nokufunda kokugqibela kobunzima. Akukho ngaphandle.
Ukukhetha iqabane lakho akukho malunga neencwadana-Kumalunga nobungqina
Ukuba iprojekthi yakho elandelayo ye-MIM ibandakanya ialloyi ze-cobalt-nickel, iindawo zokutywina ezinoxinzelelo oluphezulu, okanye iijometri ezingekho mgangathweni ezifuna ukuchaneka komda phantsi komthwalo we-thermal, tsiba uthelekiso lwekhathalogu. Buza endaweni yoko:
- Ngaba ungabelana ngeerekhodi zakho ezintathu zokugqibela zokulinganisa isithando somlilo?
- Ngaba uyayigcina imifanekiso ye-SEM egciniweyo kunye neemephu ze-EDS zamaqashiso awaliweyo?
- Uqinisekisa njani ukugqibelela kokudinwa kwe-binder-iigophe ze-TGA okanye ukwehla kobunzima bokwenyani kwindawo nganye?
- Yeyiphi eyona meko imbi kakhulu umahluko wokucutheka kwi-100 mm ubukhulu becala-kwaye uhlawula njani kuyilo lwezixhobo?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uphendula zone-ngesicelo, kunye nedatha. Indawo yabo https://www.tsingtaocnc.com ibamba iingxelo zovavanyo ezikhutshelwayo, hayi iifoto zemveliso kuphela. Amandla abo akakho isikali-kukugocagoca. Hayi umthamo-ukuqinisekisa.
Kumacandelo amashishini achanekileyo apho ukungaphumeleli kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho, i-factory yesixhobo sokubumba isinyithi esifanelekileyo ayiboneleli nje ngomgubo. Inika ubungqina.
