Izisombululo zefektri ye-metallurgy ye-powder azikho malunga nokucofa uthuli lwentsimbi lube yimilo. Bamalunga nokusombulula iintsilelo zehlabathi zokwenyani-njengombhobho we-cobalt alloy eqhekeka ngaphantsi kwe-30,000 ye-psi hydraulic surges, okanye i-piston pump yezindlu elwa nempi emva kokunyangwa kobushushu kwirigi yeoli engaselunxwemeni. Siyibonile: iindawo ezidlula i-specs yelebhu kodwa zisilele ekuqaliseni ngenxa yokuba i-gradients yoxinaniso ayizange ifakwe kwimephu kuzo zonke iindawo. Kungenxa yoko le nto ukuchaneka kungengomgca wokugqibela-yimeko yokuqala.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwifektri yeteknoloji yomgubo wesinyithi apho yonke ibhetshi yokulandeleka yelog ibandakanya umxholo weoksijini, ukuhanjiswa kobungakanani besuntswana (D50 ≤ 12.4 µm), kunye nokutenxa koxinano oluluhlaza. < ±0.03 g/cm³. Olu ayilolawulo lwethiyori. Yindlela esibambe ngayo idimensional drift to ± 0.015 mm kwi-AMS 5387 cobalt alloy 6 izindlu zempompo ze-OEM yaseYurophu yehydraulic-nangona ukufuma kwe-ambient kuma-40% ukuya kuma-85% ngexesha lokuhlangana. Isitixo? Akukho nyathelo elinye lenkqubo lizimele lodwa. Ukuphatha ipowder, ukucinezela kwe-isostatic ebandayo, i-kinetics ye-debinding, kunye neeprofayili ze-vacuum sintering zilungiswa njengenkqubo enye-kungekhona iibhokisi ezilandelelanayo kwi-flowchart.
Uninzi lwabathengi bacinga ukuba "isinyithi somgubo" sithetha iindawo ezikufutshane nenetha ezinomatshini omncinci. Kodwa izicelo ezisebenza ngokuphezulu zifuna ukwenziwa komxube. Qwalasela amacandelo asekwe kwi-cobalt ye-T800: i-sintered ukuya kwi-98.7% yoxinaniso lwethiyori, emva koko yagqitywa kumaziko e-CNC e-5-axis anezijikelezo ezipholileyo ezipholileyo ukunqanda ukubunjwa kwe-recast kwimiphezulu yokutywina ebalulekileyo. Asilukhupheli ngaphandle unyango lobushushu-sidibanisa isisombululo esidibanisayo *ngoko nangoko* emva kokuntywila ngaphakathi kwigumbi elinye lesithando somlilo, sisusa umothuko wobushushu phakathi kwemijikelo. Yiloo ndlela esiye sayifumana ngayo i-Rockwell C58-62 yobunzima obufanayo kwi-210 mm ububanzi be-winch center shaft rollers-amacandelo ajikeleza phantsi kwe-12-toni yemithwalo eguquguqukayo ngelixa exhathisa ukuqhekeka kwe-sulfide kwindawo yegesi emuncu.
Nantsi into eyahlula i-metallurgy yomgubo osebenzayo kwimveliso yempahla:
- Ukuphendula ngezinto eziphathekayo: Yonke iqashiso ye-cobalt-nickel ithwala iingxelo zovavanyo lokugaya + i-SEM-EDS yomntu wesithathu ukuqinisekiswa kwe-carbide phase dispersion-kungekhona nje i-chemistry eninzi
- Imida yejometri ebotshelelwe kwinkqubo: Siyalukhaba uyilo olunomlinganiselo > 8:1 kudonga olucekethekileyo ngaphandle kokuba ixhaswe yidatha yokulinganisa ebonisa ulungelelwaniso lwevektha eshwabeneyo.
- Ukuqinisekiswa okusebenzayo ngaphambi kokuthunyelwa: Yonke ivalve yoxinzelelo ivavanywa ngokuvuza kwe-helium kwi-1.5 × uxinzelelo olusebenzayo, hayi nje ukujonga okuphakathi
- Akukho "standard" sintering cycle: Iiparamitha zomjikelo zitshintsha ngobunzima benxalenye nganye, ubukhulu becandelo, kunye nethagethi yokugqibela yobulukhuni-kwanangaphakathi kwebakala elifanayo lealloyi
Abanye bathi i-metallurgy yomgubo ayinakuhambelana namandla enziweyo. Yinyani-kwisivuno esiqinileyo kwiimvavanyo ezilula zoxinzelelo. Kodwa kwinkonzo yokwenyani? I-Sintered AMS 5387 cylinder yezindlu yagqithisa iqabane layo elibunjiweyo nge-3.2 × kwisicelo sempompo esibuyisela ngenxa yokuba i-microstructure yayo ye-isotropic yaxhathisa ukuqaliswa kokukhathala kokuqhekeka kwimida yengqolowa. Izinto ezibunjiweyo zazihamba ngendlela eziziinkozo; Isixhobo se-sintered sasingenazo iintambo zokusebenzisa. Asikubonakalisi oku ngeencwadana-kodwa ngedatha yendawo evela kwi-17,000+ iiyure zokusebenza kumazwekazi amathathu. Xa indibano yakho yempompo ibaleka ingajongwanga kangangeentsuku ezili-14 kwindawo eyinkqantosi ekude, isotropy ayisiyomfundo. Lifikile ixesha.
Iingxoxo zeendleko zihlala ziphosa inqaku lokwenyani. Ewe-isixhobo seseti yokufa yesiko iqhuba i-28,000 yeedola - $42,000. Kodwa xa ususa imisebenzi emithandathu yesibini (ukujika, ukugrumba, ukucofa, ukugaya, ukuchama, ukudubula), ixabiso elipheleleyo lehla nge-22-37% kwimiba ephakathi (500-5,000 pcs / ngonyaka). Okubaluleke ngakumbi: ixesha lokukhokela liyancipha ukusuka kwiiveki ze-14 ukuya kwiiveki ze-5.5-kungekhona ngenxa yokuba singxamile, kodwa ngenxa yokuba siqinisekisa i-callouts ye-GD & T ngexesha lokumisa umkhenkce, ukubeka iflegi yeendawo ezinokuthi zigqwetheke ngaphambi kokuba umgubo wokuqala ubethe ukufa. Siyekile ukubala ukuba bangaphi abathengi abathe, "Besingazi ukuba i-shrinkage ibingeyomda kwiradii" -emva koko sayila ngokutsha indima yabo kwiiyure ezingama-72 kunye ne-zero tooling rework.
Ikamva lobuchwephesha bobuchwephesha bobuchwephesha bomgubo buxhomekeke kuhlengahlengiso oluvaliweyo. E-QINGDAO QIANGSENYUAN, utyalo-mali lwethu lwenqanaba elilandelayo alukho ooshicilelo bakhulu-lixesha lokwenyani lokuhlola umoya we-sintering kunye nolungiso oluqhutywa yi-AI lwendawo yombethe kunye noxinzelelo oluyinxenye phakathi komjikelo. Ngoba? Ngenxa yokuba i-spikes yokufuma ngexesha le-monsoon ibangele i-0.8% yokwahluka kwe-porosity kwiibhetshi ezimbini ngoJulayi odlulileyo. Sayibamba. Sayilungisa. Kodwa i-reactive ilungisa inkunkuma. Ulawulo oluqikelelwayo lugcina isivuno. Lowo ngumahluko phakathi kwentlanganiso ethile-kunye nokuba nenkqubo.
Ukuba iindawo zakho zokusebenza eziphezulu zifuna okungaphezulu nje "kwentsimbi engumgubo + ubushushu," ukuba zisebenza apho ukungaphumeleli kuthetha ukwehla, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho-ke i-powder metallurgy technology factory yakho kufuneka iphathe i-metallurgy njengobunjineli, kungekhona ukuvelisa. Ayinguye wonke umniki-nkonzo owenzayo. Siya.
