Cov txheej txheem ua hauj lwm thiab Technical Specifications ntawmxuab zeb casting tshuab
Kev npaj pwm
High-qib aluminium alloy lossis ductile hlau pwm yog precision-machined ntawm 5-axis CNC tshuab, ua tiav nto roughness hauv qab Ra 1.6μm. Kev sib cais-hom tsim suav nrog cov kaum sab xis (feem ntau 1-3 °) thiab cov nyiaj siv ua haujlwm (0.5-2mm) los pab txhawb kev demolding. Cov ntawv thov kev lag luam feem ntau siv cov pwm coated nrog zirconia-raws li cov txheej txheem refractory kom ntev kev pab cuam lub neej tshaj 50,000 cycles.
Sand Filling & Moulding
Chemically bonded silica xuab zeb (85-95% SiO₂) yog tov nrog 3-5% bentonite av nplaum thiab 2-3% dej kom pom lub zog ntsuab. Tsis siv neeg flaskless molding tshuab siv 0.7-1.2 MPa compaction siab, ua tiav pwm hardness ntawm 85-95 ntawm B-scale. Rau lub cav thaiv castings, sodium silicate-CO₂ hardened cores nrog venting channel yog tso ua ntej pwm kaw.
Pwm Assembly & Fixation
Robotic vision systems align pwm halves nyob rau hauv ± 0.2mm kam rau ua, thaum interlocking locator pins tswj kev sau npe nkag. Heavy-duty C-clamps exert 15-20kN clamping quab yuam, ntxiv los ntawm qhov hnyav blocks rau pwm loj (> 500kg). Foundries nce siv electromagnetic locking rau high-volume ntau lawm.
Ncuav
Khoos phis tawj tswj qaij-ntug rauv tuav cov hlau superheat ntawm 50-80 ° C saum cov kua dej kub. Advanced systems feature laser-theem sensors thiab PID-tswj lub rooj vag ntws, ua tiav qhov kev ruaj ntseg hauv ± 2%. Rau txhuas alloys (A356-T6), raug pouring speeds li 1-3 kg/sec kom txo turbulence.
Txias & Solidification
Lub sij hawm Solidification ua raws li Chvorinov txoj cai (t = k·(V/A)²), qhov twg k-tus nqi sib txawv ntawm 0.5 min / cm² rau nyias seem mus rau 2.5 min / cm² rau hnyav castings. Kev tso tawm tswv yim ntawm exothermic risers (15-20% ntawm casting ntim) them nyiaj rau shrinkage hauv cov cheeb tsam tseem ceeb.
Shakeout & Ntxuav
Vibratory conveyors nrog 5-10G acceleration cais 90% ntawm cov xuab zeb rau thermal reclamation. Multi-theem tumblers muaj xws li teb tumblers rau thawj deburring, ua raws li robotic abrasive blasting siv 0.3-0.6 hli steel grit ntawm 60-80 psi.
Kev soj ntsuam & Tom qab ua tiav
Kev sib koom tes ntsuas tshuab (CMM) txheeb xyuas qhov loj me rau ISO 8062 CT8-10 tus qauv. X-ray tomography kuaj pom cov teeb meem sab hauv mus txog 0.5mm daws teeb meem. T6 kev kho cua sov rau txhuas suav nrog kev daws teeb meem ntawm 540 ° C ± 5 ° C ua raws li kev laus laus.
Core Advantages:
Geometry yooj yooj yim ua rau cov qauv hollow (xws li, twj impellers nrog 0.5mm phab ntsa thickness)
Khoom siv ntau yam hla ferrous / non-ferrous alloys (HT250 grey hlau rau AZ91D magnesium)
40-60% txo cov nqi cuab yeej vs. tuag casting rau prototypes
Limitations & Mitigations:
Kev siv zog txo qis los ntawm kev siv cov xuab zeb automated
Pwm pov tseg los ntawm 85-90% xuab zeb reclamation tus nqi
Nto tiav cov kev txwv (Ra 12.5-25μm) kov yeej los ntawm precision machining
