Xa iinjineli zifuna a isiko elilahlekileyo umzi-mveliso wokulahla kwiindawo ezimele zibambe ukunyamezela kwe-± 0.02 mm phantsi kwe-350-bar yoxinzelelo lwe-hydraulic, azibizi iziseko eziqhelekileyo. Babiza iivenkile ezine-cobalt alloy heat-treat-treatment logs kwifayile, iingxelo zeCMM ezigxininiswe yi-ISO 9001 abaphicothi-zincwadi, kunye namava okuthumela i-AMS 5387 yezindlu zepompo kwi-Tier-1 ababoneleli benkonzo ye-oilfield e-Houston nase-Aberdeen. Leyo yinyani yokusebenza-hayi ulwimi lokuthengisa.
Kutheni “isiko” Sithetha Ngakumbi kunesitampu nje sokuzoba
Ilahleko yokuphosa iwax ayiqhelekanga kuba uthumela ifayile ye STEP. Kuyinto yesiko xa i-Foundry ithintela umngcipheko woyilo ngaphambi kokuba kuqalise izixhobo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siye sabona iindawo ezintathu zokungaphumeleli eziphindaphindiweyo kuyilo lomzimba wevalvu ethunyelwe ngumxhasi: okokuqala, amacandelo amancinci angaphantsi kwe-4.2 mm aqhekeka ngexesha lokunciphisa uxinzelelo lwe-post-cast; okwesibini, iradiya yangaphakathi eyimfama engaphantsi kwe-R1.5 ebamba intsalela yeqokobhe leceramic; okwesithathu, ii-callouts ze-GD & T ezichaza iphrofayili yendawo ngaphandle kokuchaza i-datum precedence-ebangela ukungasebenzi kakuhle kwiindibano zempompo zepiston. Siyihlaba indwe ngexesha lophononongo lobunjineli-kungekhona emva kokukhatywa. Yiloo ndlela "isiko" liba liqikelelo, lingasebenzi.
UkuPhathwa kwe-alloy ye-Real-World, hayi amaBango ePhepha leDatha
I-cobalt-nickel alloys efana ne-T800 kunye ne-AMS 5387 ayenziwanga-i-coaxed. I-thermal conductivity yabo yi-1/6 ye-304 engenasici. Isantya sokusebenza nzima sinyuka emva kwe-0.15 mm yobunzulu bokusika. I-carbide esemgangathweni ifaka i-shatters kuqhagamshelwano lokuqala. Sisebenzisa izixhobo ze-ceramic ezigqunywe nge-PVD, isikhukula sokupholisa kuxinzelelo lwebar engama-42, kwaye sinciphise ubunzulu be-axial ukuya kwi-0.08 mm ngokudlula. Oku akuyothiyori. Kungenxa yeso sizathu imilomo yethu ye-cobalt alloy iphila kwiinyanga ezili-18 kwiimpompo ze-slurry zesantya esiphezulu ngelixa abakhuphisana nabo behluleka kwiinyanga ezi-5. Silandelela ijiko ngalinye lobunzima bebhetshi, ubungakanani bobungakanani bengqolowa, kunye nokwahlulwa kwe-interdendritic-kuba i-microstructure imisela ubomi bokudinwa, hayi nje amandla okuqina.
Udibaniso oluthe nkqo unokulinganisa
Uninzi lwababoneleli abakhuphela ngaphandle, ukwenza oomatshini, okanye ukugqiba. Oko kudala ukukhukuliseka okulinganayo. Ukuncipha kwepateni ye-wax ayihambelani nokunxitywa kwe-CNC. Ukugqwethwa konyango lobushushu akuhlawulwa kwi-milling yokugqibela. Kwiziko lethu laseQingdao, iqela elinye liphethe ikhonkco elipheleleyo: utyalo-mali → ukuphelisa uxinzelelo → i-5-axis CNC contouring → HVOF coating → ukuvuza uvavanyo. Kwindlu yesilinda yempompo yepiston, oku kuthetha ukuba ukuphuma kwempompo kukonke kuhlala ngaphantsi kwe-0.015 mm ngaphaya kwe-320 mm ubude-iqinisekiswe yilaser tracker, hayi nje iCMM. Akukho handoffs. Akukho tyala imidlalo. Ulawulo lwenkqubo elandelekayo ukusuka kwinaliti yewax ukuya kwingxelo yokugqibela yokuhlola.
- Imathiriyeli ekrwada eqinisekisiweyo kwi-ASTM A975 / AMS 5737 enengxelo ezipheleleyo zovavanyo lokusila
- Ukuhlolwa okungaphakathi kwenkqubo: ukuqinisekiswa kobukhulu beqokobhe, ipateni yewax yophicotho-nzulu, ukuqina konyango lwangaphambili.
- Ukuqinisekiswa kokugqibela: uvavanyo lokuvuza kwe-helium ukuya kwi-1 × 10⁻⁹ mbar · L / s, uburhabaxa bomphezulu Ra ≤ 0.8 μm ebusweni obubalulekileyo bokutywinwa, ukumelana nokutshizwa kwetyuwa ≥ iiyure eziyi-1,000 nge-ASTM B117
Oko Kufunwa Ngabathengi Ngokwenene—Asiyiyo Into Ethembisa Iincwadana Ezinemifanekiso
Abaphathi beentengo babuza imibuzo emithathu-kwaye bafumane iimpendulo ezingacacanga kwenye indawo:
"Ngaba ungabamba indawo yokwenyani kwimingxuma emithandathu ye-Ø8.5 mm ngaphakathi kwe-0.01 mm ukuya kwidatum esekwe kumphezulu wokuphosa?" Ewe-ukuba i-angle yedrafti yokuphosa i-≥ 1.2 ° kunye nomphezulu we-datum umatshini owenziwe wacaba ngaphambi kokugrumba umngxuma. Siza kukubonisa uyilo lomdlalo.
"Lithini ixesha lakho lokukhokela kwiziqwenga ezili-12 zeplagi ye-AMS 5387 ene-pitch yentambo engekho mgangathweni?" Iintsuku ezingama-28 ukusuka ekufumaneni imvume. Hayi "iiveki ezi-4-6." Hayi “phantsi kokufumaneka kwezinto eziphathekayo.” Sigcina iibhiliti ze-T800 kwaye sigcine izivumelwano ezinemithombo emibini kunye nabanikezeli be-cobalt abaqinisekisiweyo be-AMS eTshayina naseJamani.
"Ngaba uyalixhasa iNqanaba lesi-3 lePPAP kwiinkqubo ze-automotive hydraulic?" Ewe-kunye namaxwebhu apheleleyo e-DFMEA, imizobo yokuhamba kwenkqubo, kunye nezifundo ze-MSA kuzo zonke iimpawu ezibalulekileyo. Hayi nje uluhlu lokutshekisha.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza apho iindawo zentsimbi ezichanekileyo zidibana nesiphumo sokwenyani. Xa i-winch centre shaft roller ingaphumeleli kwi-crane ye-offshore, ixesha lokuphumla lixabisa i-$ 220,000 / iyure. Xa i-valve yoxinzelelo ivuza kwimodyuli yokulawula i-subsea, ukutshintshwa kufuna ukungenelela kwe-ROV kwi-2,800 yeemitha. Akukho ndawo "yokuvala ngokwaneleyo." Yiyo loo nto abathengi bebuya-kungekhona ngexabiso, kodwa ngokuqiniseka komgangatho, ukuhambelana kwe-metallurgical, kunye nentsebenziswano yobunjineli ebhakiweyo kuyo yonke isicatshulwa. Ngexesha elizayo xa ucacisa icandelo loxinzelelo oluphezulu, ukugqoka okuphezulu, okanye inkonzo ebaluleke kakhulu ye-corrosion, qalisa ngokwenziwa kwe-manufacturability-kungekhona nje ijometri. Ithagethi yakho yokuthembeka ixhomekeke kuyo.
