Cov Khoom Siv Hloov Kho thiab tsis ua haujlwm rau lub caij nplooj hlav clips
- Dab tsi yog qhov kev txhim kho hauv kev ua tau zoo thiab corrosion tsis kam thaum txhim kho elastic strips los ntawm 60si2mn rau 60si2mncr (0.8% -1.2% cr), thiab muaj kev pabcuam li cas?
Cr Reflines nplej (15 → 8μm), ua rau muaj zog nkees (3506 35 500MPA), ncua lub neej txij li 1 mus rau 2.5 lab mus ncig. Nws tsim cov yeeb yaj kiab 0.01mm Kev pabcuam lub neej ntev los ntawm 3-4 txog 8 xyoo. Tswj CR DEGiation (± 0.1%) rau tsawg dua lossis sib npaug rau 10% lub neej hloov pauv.
- Yuav ua li cas kom paub tsis ua tiav cov lus ceeb toom ntawm kev ntxhov siab ntawm kev nyuaj siab ntawm kev saib xyuas, qhov twg los teeb tsa cov ntsiab lus, thiab yuav teeb tsa cov ntsiab lus li cas?
Method: Attach 0.1με strain gauges to strip roots, transmit data wirelessly (10Hz). Key points: ① Root arc (max stress); ② Gauge block contact (wear stress); ③ Clamping end (force transfer). Thresholds: ① >450MPa stress; ② >50MPa fluctuation; ③ >8% kev noj qab haus txhua hnub. Tshawb xyuas cov ntaub ntawv tom qab ceeb toom kom tsis txhob ua tiav.
- Yuav ua li cas inhibit deg reg microcrack (0.8mm × 0.2 hli) kev sib tw ntawm anceast- kev laus, thiab yuav sim dab tsi tom qab kev kho mob?
Cov kauj ruam: ① Ua kom sov txog 320℃ntawm 50℃/ h, tuav 2h; ② Txias rau 150℃ntawm 30℃/ h, tuav 1h; Cua txias. Kev Ntsuas: ① Tsis muaj kev loj hlob tawg; ② HB320 - 350 Hardness; Mob siab dua lossis sib npaug li 2 lab-voj voog lub neej; ④ 12-15kn clamping lub zog. Txo kev hais tawm txog 0.02mm / xyoo, txuas lub neej los ntawm 3-4 xyoos.
- Yuav ua li cas rau xaiv cov ntaub ntawv me me raws li kab kev co zaus ntau (10Hz siab}
Xaiv: ① 10Hz dog dig: 60si2mn (¥ 15 / daim, 1 lab mus); ② 25Hz siab - ceev: 60si2mnni (0.5%-}}}}}}}}} ③ 15Hz hnyav- haul: 60si2mncr (2.5 lab mus los). Basees: Kev co-qaug zog curves, kom muaj ntau dua lossis sib npaug rau 8 xyoo lub neej, tsawg dua lossis sib npaug ntawm 2% kev ua tsis tiav.
- Dab tsi ua rau elrance sawb clamping yuam lawb mus rau 80% (15 → 12kn) tsis muaj kev tawg, thiab yuav ua li cas los ntawm cov tsev pheeb suab theem nrab, thiab yuav ua li cas thiaj li tshawb xyuas?
Cov laj thawj: ① 0.3mm yas deformation; ② 0.2 hli kev sib ntsib; ③ 50℃kub hloov pauv. Kev Txum Tim Rov Qab: ① Preload mus rau 10mm rau 24h; ② rov qab rau 14-15kn. Kev txheeb xyuas: ① 14-15knch yuam; ② 200-220gpa modulus; Muaj ntau dua los yog sib npaug rau 1.8 lab mus; ④ tsawg dua lossis sib luag rau 0.1mm deformation. Ncua lub neej los ntawm 5 xyoo, txuag 70% nqi.
