Xa iinjineli zichaza ukuphoswa kwesanti yentsimbi kwiivalvu zehydraulic ezinoxinzelelo oluphezulu okanye i-winch center shafts, abakhethi nje inkqubo-babheja ngozinzo lwe-dimensional, ulawulo lwe-microstructure, kunye ne-batch-to-batch metallurgical consistency. Yiyo loo nto a ifektri yokugalela isanti yentsimbi kufuneka yenze okungaphezulu kunokugalela isinyithi esinyibilikisiweyo kwizibumba. Kufuneka idibanise isayensi ye-Foundry kunye nomatshini ochanekileyo, ukulandelwa kwezinto eziphathekayo kunye nokuqinisekiswa okusebenzayo-kwaye uhambise iindawo ezisinda kwi-20,000 psi cycles ngaphandle kokunciphisa.
Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye sabona indlela ukuprintwa kwe-core engafanelekanga kubangela i-0.15 mm ukuhlukahluka kodonga kwi-piston pump cylinder housings-ngokwaneleyo ukukhupha i-cavitation kwi-3,200 rpm. Siye sabona abathengi belahla amaqashiso onke ngenxa yokuba i-cobalt-nickel castings ipholile ngokukhawuleza, isenza isigaba se-brittle sigma ecaleni kwemida yeenkozo. Ezi ayingomngcipheko wethiyori. Ziindlela zokungaphumeleli eziphindaphindiweyo-kwaye yiyo loo nto indawo yethu ehambelana ne-ISO iphatha wonke umsebenzi wokulahla isanti yentsimbi njengenkontileka yesinyithi, hayi ukwenziwa kwemveliso.
Ukuhlanganiswa kwethu ngokuthe nkqo kuphelisa ezona ngongoma zixhaphakileyo zentlungu kwimixokelelwane yokubonelela nge-alloy ephezulu. I-Foundry, unyango lobushushu, i-multi-axis CNC, kunye nokugqitywa komphezulu konke kwenzeka phantsi kophahla olunye-kunye nemigangatho ekwabelwana ngayo ye-GD&T, iiprothokholi zokuhlola ezilungelelanisiweyo, kunye nexesha lokwenyani le-CMM ingxelo ejijelwe emva kuyilo lokubumba. Xa u-odola inxalenye yempompo ye-cobalt ye-cobalt ye-AMS 5387, enye injineli eqinisekisa umzobo wakho iphinda isayine kwilog yesithando somlilo, izinga lokucima, kunye novavanyo lokugqibela lobulukhuni beRockwell C. Akukho handoffs. Akukho lahleko yoguqulelo. Iqela nje elinye eliphendulayo.
- Ingqibelelo yezinto eziphathekayo iqala ngaphambi kokunyibilika: Sifumana i-T800 eqinisekisiweyo ye-cobalt-based kunye ne-stainless steel ingots kunye neengxelo ezipheleleyo zokuvavanya i-mill-kungekhona nje amagama ebakala. Ibhetshi nganye yenziwa uhlalutyo lwe-spectrographic xa ifunyenwe, kwaye sigcina iisampulu iminyaka emi-5.
- Ukuchithwa kwesanti "akukokuchaneka okuphantsi" apha: Iipateni zethu eziluhlaza-isanti kunye ne-resin-bonding zifezekisa i-± 0.3 mm ukunyamezela komgca kwiimpawu ze-300 mm-ziqinile kunokuba abaninzi abatyali-mali bafaka izicelo ze-alloys ezifanayo-kuba silawula umswakama, ukunyanzeliswa koxinzelelo, kunye nokugubha ixesha ukuya kweyesibini.
- Umatshini ulandela ukuphosa-hayi enye indlela: Sisebenza ngomatshini iindawo zokutywina ezibalulekileyo *emva* kokuthomalalisa uxinzelelo kunye nokuguga, hayi ngaphambili. Oko kuthintela ukuphazamiseka kwimizimba yevalvu yoxinzelelo apho i-0.02 mm ukuphambuka kwe-flatness kubangela ukuvuza ngaphezu kwe-10,000 psi.
Abanye banokuxoxa ukuba ukuphosa isanti akukwazi ukuhambelana nokuphosa utyalo-mali kwiijometri ezinzima. Kodwa ekusebenzeni, sivelisa iziseko zempompo ezingezizo ezisemgangathweni kunye neziteshi zokupholisa zangaphakathi, i-undercuts, kunye ne-lugs edibeneyo yokufaka-usebenzisa i-split-pattern tooling kunye ne-ceramic cores-ngelixa ubambe ukuhluka kobunzima phantsi kwe-± 1.2%. Umehluko? Asiyiphathi ijometri njengesithintelo. Siyiphatha njengeparamitha yoyilo ekufuneka yenziwe ecaleni kwendlela yobushushu kunye nokuqina.
Umgangatho awuphicothwa ekugqibeleni-wakhiwe kuwo onke amasango. Ukuqinisekiswa kwezinto ezikrwada ezingenayo. Kwinkqubo yokuhlola i-radiographic kumacandelo abalulekileyo ensimbi kunye neentsimbi zensimbi ezingenasici. Uvavanyo lokugqibela olusebenzayo: uxinzelelo lwe-hydrostatic lubambe kwi-1.5 × ukulinganisa uxinzelelo lokusebenza kwimizuzu ye-30, kunye nokukhutshwa kwe-bubble zero. Ingxelo nganye inenombolo yeqashiso, inombolo yobushushu, i-ID yomsebenzisi, kunye nesitampu sexesha. Yonke inxalenye iyalandeleka-kungekhona nje kwibhetshi, kodwa kumjikelezo wesithando somlilo kunye netanki yokucima esetyenzisiweyo.
Sinikezela ngee-OEM zemoto yobunjineli ezifuna iirola ze-winch zeshaft ezine-62 HRC yobulukhuni bomphezulu kunye ne-0.4 µm Ra ukugqibezela-ngamaxesha okukhokela amafutshane kuneenkampani ezikhuphisana nehlabathi ukucaphula iiprototypes. Sixhasa izihlanganisi zenkqubo yoxinzelelo lwe-hydraulic ezifuna iivalvu zoxinzelelo ezinezitulo zezihlalo ezitshintshayo ezenziwe ngoomatshini ukusuka kubushushu obufanayo bokuphosa njengomzimba-ukuqinisekisa ukuziphatha okufanayo kokwanda kwe-thermal. Kwaye sisebenzisana nabenzi bezixhobo ze-oyile kunye negesi abafuna imilomo ye-AMS 5387 ene-zero porosity kwicandelo lomqala, ingqinwe yi-micro-CT scanning.
A ifektri yokugalela isanti yentsimbi uzuza ukuthenjwa kungekhona ngeencwadana ezinemifanekiso—kodwa ngento eyenzayo xa iphepha elithile lishiya ithuba lokutolika. Xa umzobo wakho uthi "R0.5 max," sijonga ukuba loo radius ichaphazela ukuhlukana kokuhamba kwindlu yakho yempompo-kwaye iphakamisa i-R0.8 ukuba idatha ibonisa ukuba iphucula ukusebenza kakuhle nge-3.7%. Xa ishedyuli yakho ifuna ukuhanjiswa kwenqaku lokuqala kwiintsuku ezili-18, siphinda silandelelanisa unyango lobushushu ukunqanda ukulibaziseka kwempelaveki-ngaphandle kokuncama amandla okuqina.
Ukujonga phambili, siwenza nzulu umsebenzi wethu kwiinkqubo zokwenziwa komatshini womxube: sifaka iidowuli zolungelelwaniso ngoomatshini ngokuthe ngqo kubumba lwesanti, sisebenzisa i-in-situ esweni lobushushu ukulungelelanisa amazinga okupholisa phakathi kokuthululwa, kunye neenkqubo ezintsha zokubopha umphezulu ocolekileyo wokugqityezelwa kwi-carbon steel castings yecandelo elikhulu. Ayizomfuniselo zaselebhu ezi. Zizisombululo ezivavanyiweyo kwiitoni ezingama-42 zeemoto zeemoto zobunjineli kunye neendibano zempompo zangaphantsi kolwandle ezilinganiswe kubunzulu be-3,000 yeemitha.
Ukuba iprojekthi yakho elandelayo ibandakanya intsimbi okanye isinyithi esingenasici esimele senze phantsi koxinzelelo, ukunxiba, okanye ukubola-ungalungiseleli umthengisi obona ukuphosa njengenyathelo elizimeleyo. Khetha iqabane eliphatha konke ukuthululwa njengekhonkco lokuqala kwikhonkco lokuchaneka, ukuphendula, kunye nobungqina bokuqina kwezoshishino.
