Thaum engineers qhia ductile hlau peev casting rau cov hydraulic li qub lossis cov twj tso kua mis, lawv tsis yog xaiv cov khoom siv xwb-lawv tau cog lus rau qhov ruaj khov nyob rau hauv 350-bar siab, microstructural sib xws thoob plaws 500-ib pawg, thiab xoom kam rau graphite nodule pawg. Yog vim li cas xaiv txoj cai ductile hlau peev casting Hoobkas tsis yog hais txog cov kab kos peev xwm lossis daim ntawv pov thawj ISO ib leeg. Nws yog hais txog leej twg validates GD&T callouts ua ntej tooling pib-thiab leej twg ntes ib tug 0.012 hli phab ntsa-thickness sib txawv thaum lub plhaub-dip soj ntsuam, tsis yog tom qab kev kho cua sov.
Vim li cas hlau hlau peev casting ua tsis tau - ua ntej nws txawm pib
Peb tau pom peb qhov rov tshwm sim hauv paus hauv ntau qhov tsis lees paub: qhov tsis sib xws nodularization vim qhov tsis tau lees paub muaj pes tsawg leeg; plhaub-pwm distortion los ntawm ceev dewaxing mus; thiab deg carbon pickup thaum kub-kub sintering ntawm ceramic plhaub. Tsis muaj dab tsi tshwm sim hauv daim ntawv qhia txog kev ntsuas tensile. Txhua qhov tshwm sim tsuas yog hauv kev ua tsis tiav - zoo li lub twj tso kua mis piston vaj tse tawg ntawm 18,000 teev ua haujlwm tsis yog qhov ntsuas 45,000. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho cov hlau tsis zoo li cov khoom lag luam tab sis raws li cov txheej txheem metallurgical. Txhua lub yaj pib nrog ntawv pov thawj Fe-Si-Mg master alloys-tsis yog generic nodulizers-thiab txhua batch undergoes spectrographic pov thawj * ua ntej * pouring. Peb tuav nodularity siab tshaj 85% (ib ASTM A536 Qib 65-45-12) hla txhua ntu tuab dua 40 hli - tsis yog ntawm cov ntawv xeem.
Vertical kev koom ua ke uas kaw hauv kev ua haujlwm - tsis yog qhov chaw xwb
Feem ntau cov foundries tso tawm castings rau peb-tog machinists. Qhov ntawd ua rau muaj qhov tsis sib xws: thermal distortion ntawm casting thiab machining, mismatched datum references, thiab ploj traceability thaum cov ntaub ntawv kho cua sov tsis ua raws li CNC cuab yeej-txoj kev cav. QINGDAO QIANGSENYUAN muaj cov saw tag nrho-los ntawm plhaub pwm tsim los ntawm tsib-axis milling thiab nitride nto hardening. Rau lub winch center ncej cov menyuam yuav tsum tau ± 0.005 hli roundness thiab 58 HRC nto hardness, qhov no txhais tau tias machining thaum lub casting tseem nyob rau hauv 20 ° C ntawm nws cov kev ntxhov siab-relief kub. Tsis muaj re-fixturing. Tsis rov ntsuas dua. Tsuas yog ib tug datum, ib tug thermal keeb kwm, ib tug accountability kab. Peb tau txiav lub sij hawm nruab nrab ntawm cov hlau txuas rau cov hlau sib txuas los ntawm 37% piv rau cov qauv sib cais-tsis yog los ntawm kev maj, tab sis los ntawm kev tshem tawm kev ua haujlwm qeeb thiab rov ua haujlwm dua.
Qhov twg "precision" raws li lub ntiaj teb hnav tiag tiag
Ductile hlau peev casting muab tus nqi tsuas yog thaum geometry matches muaj nuj nqi-tsis catalog specs. Xav txog AMS 5387 cobalt alloy twj tso kua mis impeller hub cam khwb cia hlau ductile rau nqi-tsav prototyping. Nws qhov kev sib txuas nrog cov hlau tsis muaj steel ncej yuav tsum muaj kev cuam tshuam zoo tom qab 12,000 thermal voj voog. Standard shrink allowances poob ntawm no. Peb pab neeg siv finite-element solidification modeling los kwv yees kev sib cog lus hauv zos hauv hubs nrog 3: 1 thickness ratios-thiab kho cov qauv siv quav ciab raws li. Peb tau xa lub tog raj kheej vaj tse rau cov twj tso kua dej siab siab qhov twg bore straightness nyob rau hauv 0.008 mm tshaj 320 mm ntev, txheeb xyuas los ntawm laser-tracked CMM scanning-tsis plug gauges. Qhov tseeb ntawd tsis yog hmoov zoo. Nws yog calibrated plhaub nthuav cov ntaub ntawv, tswj dewaxing ramp tus nqi, thiab real-time melt kub logging synced rau txhua ncuav.
Xaiv koj cov ductile hlau peev casting Hoobkas - dhau ntawm daim ntawv qhia
Nug plaub nqe lus nug no ua ntej kos npe rau PO:
- Koj puas tuaj yeem muab cov ntawv pov thawj raw khoom rau peb qhov kawg melts ntawm Qib 65-45-12-thiab paub meej tias kev taug qab mus rau cov xov tooj cua sov? (Tsis yog tsuas yog daim ntawv pov thawj zeb-cov ntaub ntawv txheeb xyuas qhov tseeb.)
- Qhia peb koj qhov nodularity daim ntawv qhia raws tu qauv rau 120 kg valve lub cev. (Koj puas ntu thiab etch txhua qhov ntau - lossis cia siab rau kev sib raug zoo ntawm ultrasonic velocity?)
- Yuav ua li cas koj validate seem stability tom qab kev nyuaj siab nyem? (Peb siv optical 3D scanning ua ntej thiab tom qab anneal ntawm thawj kab lus - tsis yog CMM qhov chaw kuaj xyuas xwb.)
- Dab tsi yog koj qhov siab tshaj plaws phab ntsa-thickness variation kam rau ua lag luam-cam khwb cia hlau hlau siab tshaj 35 hli? (Peb cov lus teb: ± 0.8 hli - txheeb xyuas rau ASME B16.34 Annex F.)
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm los ntawm Qingdao nrog kev txhawb nqa engineering ncaj qha rau North America, Europe, thiab Southeast Asia cov neeg siv khoom. Peb tsis muag castings. Peb xa cov kev ua haujlwm ncaj ncees - ntsuas hauv lub sijhawm ua haujlwm, tsis yog qhov hnyav hnyav li. Thaum koj qhov kev ua haujlwm hnyav ntxiv tom ntej xav tau ob qho tib si hlau lub zog thiab kev nqis peev casting qhov ncaj ncees, pib nrog leej twg ntsuas dab tsi - thiab thaum twg.
