Thaum cov engineers qhia cov khoom siv txhuas rau hydraulic manifolds, lub twj tso kua mis, lossis lub cev muaj zog siab, qhov ruaj khov thiab microstructural tsis sib xws tsis yog xaiv tau - lawv tsis tuaj yeem sib tham. Yog vim li cas ntau North American thiab European OEMs tam sim no los ntawm ib poob ciab aluminium casting Hoobkas uas kho cov peev casting tsis yog tus txheej txheem standalone, tab sis raws li thawj kauj ruam precision nyob rau hauv nruj tswj hybrid workflow. Peb tau pom cov neeg siv khoom rov qab peb zaug - thawj zaug rau cov qauv, thib ob rau nruab nrab-batch validation, thib peb rau tag nrho-series ntau lawm - vim hais tias lawv cov neeg muag khoom yav dhau los tsis tuaj yeem tuav ± 0.05 hli ntawm nyias-walled aluminium flanges tom qab kho cua sov. Lub hauv paus ua rau? Qhov sib txawv ntawm kev ua tau zoo ntawm casting thiab kev qhuab qhia tom qab cam khwb cia.
Vim li cas "Poob Wax" Ib leeg tsis lees paub qhov tseeb-Thiab ua li cas
Poob ciab aluminium casting muab ze-net-puab geometry-tab sis tsuas yog tias tag nrho cov saw yog tsim los rau kev ua haujlwm zoo. Ntawm peb qhov chaw nyob hauv Qingdao, peb pib nrog AMS 4117 lossis A380 alloy daim ntawv pov thawj rau ASTM B179, tom qab ntawd txheeb xyuas cov qauv ntawm cov qauv metallographic ua ntej lub plhaub pwm sib dhos. Tseem ceeb heev, peb tsis outsource siv quav ciab qauv cuab yeej: peb nyob rau hauv-lub tsev CNC-machined aluminium masters tso cai rau peb los kho cov cua ntsawj ntshab lub kaum sab xis thiab gating txoj hauj lwm nyob rau hauv 0.02 hli - qhov tseem ceeb thaum casting lub tog raj kheej vaj tse nrog cov cua txias raws li 2.5 hli phab ntsa thickness.
Peb tau pom tias 70% ntawm qhov seem drift hauv txhuas peev castings tshwm sim thaum lub sij hawm de-waxing thiab burnout - tsis pouring. Peb cov programmable kilns ramp ntawm 0.8 ° C / min mus txog 1050 ° C, tuav rau 90 feeb kom tshem tawm cov khoom seem uas tsis tau tawg silica-alumina plhaub. Qhov kev tswj hwm tseem ceeb tshaj plaws rau qhov chaw xws li piston twj tso kua mis lub tog raj kheej vaj tse, qhov chaw thermal shock thaum lub sij hawm burnout tsim micro-cracks uas tom qab propagate nyob rau hauv cyclic siab.
Tsis zoo li cov khw muag khoom xuab zeb uas kho cov txhuas ua "yooj yim rau ncuav," peb saib xyuas qhov kub ntawm ± 3 ° C siv dual thermocouple immersion probes - thiab tsis lees txais ib qho batch uas cov ntsiab lus hydrogen ntau dua 0.12 ml / 100g ( ntsuas los ntawm lub tshuab nqus tsev vacuum solidification test). Qhov no tsis yog overkill; Nws yog li cas peb ua tiav tensile zog ≥310 MPa hauv T6-kho A380 vaj tse thaum tuav elongation> 3.5%.
Qhov twg Casting Ends thiab tiag Engineering pib
Nov yog qhov feem ntau poob ciab aluminium casting Hoobkas Cov npe yuav tsis qhia rau koj: peev casting qhov tseeb degrades sai tshaj 300 hli hauv ib qhov ntev. Tias yog vim li cas peb lub xov tooj ntawm tes CNC zaum meters los ntawm cov kab nrib pleb-tsis hla lub warehouse. Peb tshuab qhov tseem ceeb sealing nto, mounting qhov, thiab bearing bores nyob rau hauv 4 teev ntawm shakeout, txo kev ntxhov siab nyob rau hauv lub txhuas matrix.
Peb siv tsib-axis ib txhij machining rau qhov chaw xws li winch center ncej chais, qhov concentricity ntawm 120 hli OD phau ntawv journal thiab 65 hli ID bore yuav tsum tuav 0.015 hli tag nrho cov qhia nyeem. Tsis muaj kev kho cua sov tom qab ua haujlwm tshwj tsis yog tias tau teev tseg-vim reheating cuam tshuam cov nplua-grained nto txheej tsim thaum lub sij hawm tswj solidification. Hloov chaw, peb siv vibratory kev ntxhov siab rau 30 feeb ua ntej kev soj ntsuam CMM zaum kawg.
Peb cov txheej txheem tshuaj xyuas tsis yog daim ntawv teev npe-tsav-nws yog kev ua haujlwm-tsav. Rau lub siab li qub, peb siv tsis tau tsuas yog GD&T callouts tab sis qhov tseeb lub rooj zaum tus nqi tawm tsam ISO 5208 Class A cov qauv. Txhua feem nqa ib daim ntawv qhia txog kev taug qab txuas nws tus lej xov tooj rau cov ntaub ntawv pov thawj raw khoom, cov cav tov rauv, CMM cov ntawv ceeb toom, thiab cov ntaub ntawv kuaj helium.
Thaum Cobalt Alloys nkag rau hauv daim duab-Thiab yog vim li cas Aluminium tseem coj
Qee qhov xav tias cobalt-nickel qhov chaw txhais tau tias tso tseg aluminium. Tsis nyob ntawm no. Peb niaj hnub cam khwb cia txhuas vaj tse uas integrate cobalt alloy nozzles (AMS 5387) ntawm precision xovxwm-fitting-tsim nrog ultrasonic daim ntawv cog lus kuaj. Aluminium lub cev tuav cov qauv kev ua haujlwm; cov cobalt ntxig tiv thaiv kev yaig ntawm 220 ° C dej kub. Qhov kev sib xyaw ua ke no txo tus nqi los ntawm 38% piv rau monolithic cobalt casting thaum ntsib API RP 14E tshaj tawm txwv.
Peb tau tsim 17 iterations ntawm ib tug tsis-tus qauv T800-raws li lub twj tso kua mis plunger qhia nplhaib-txhua refined raws li teb tsis ua hauj lwm tsom xam los ntawm offshore roj rigs. Tab sis cov lus qhia ncaj qha tau txhim kho peb cov txheej txheem aluminium casting: nruj dua tswj ntawm interdendritic spacing txo porosity hauv A380 valve lub cev raug rau H₂S-laden kua. Kev paub txog cov khoom siv tsis yog siloed - nws yog hla-pollinated.
Peb cov kev npaj tsim tawm ntshiv ua kom cov qauv coj ua lub sijhawm nyob qis dua 21 hnub - txawm tias nyuaj rau geometries xav tau kev cai ceramic cores. Rau qhov kev txiav txim ntim, peb khaws cov khoom tsis sib xws ntawm cov khoom siv sib xyaw thiab cov khoom siv plhaub, yog li cov khoom siv traceability tsis dhau los ua tus xa khoom xa tuaj.
Xaiv ib tus khub, tsis yog tus muab khoom xwb
Yog tias koj qhov project aluminium casting tom ntej no suav nrog cov phab ntsa nyias, sab hauv txoj kev, lossis kev ua siab ntev ntawm cov khoom siv, nug cov lus nug no ua ntej kos npe rau PO:
- Koj puas tuaj yeem qhia CMM cov ntaub ntawv pov thawj raws li-cam khwb cia flatness ntawm 150 × 150 mm flange nto?
- Koj puas ua hydrogen tsom xam ntawm txhua qhov ntau yaj - lossis tsuas yog ib lub lim tiam?
- Puas yog koj CNC programming ua tiav hauv tsev, lossis tawm mus rau lwm tus neeg muag khoom?
- Dab tsi yog koj cov ntaub ntawv txheej txheem los txheeb xyuas qhov tseem ceeb ntawm kev hloov pauv hauv cov ntu hollow?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb tag nrho plaub nrog cov ntaub ntawv pov thawj-tsis yog phau ntawv qhia. Peb tsis muag cov kev pabcuam casting. Peb xa cov khoom siv txhuas ua haujlwm uas muaj sia nyob 10,000+ lub voj voog nyob rau hauv hydraulic systems, 5-xyoo kev xa mus rau hauv cov twj tso kua mis marine, thiab kev ua haujlwm tas mus li hauv engineering tsheb winches. Qhov kev ntseeg tau pib ntev ua ntej cov quav ciab melts - thiab xaus tsuas yog tom qab koj tus neeg siv kawg kos npe tawm.
