Ua kom zoo rau txoj kev sib ze nkhaus ntawm lub siab ntawm lub siab thiab ntxiv dag zog rau cov kab hlau txuas ntxiv
- Yuav ua li cas thiaj ua kom zoo dua 60kg / m kev tsheb ciav hlau khi rau 0.8mm tom qab kev hloov pauv / 1 xyoo hauv 25T nkhaus nkhaus (800m vojvoog) ntawm kev sib chwv nto?
Tiaj tus contests contrencing concentration. Optimization: ① 48-52mm arc tiv tauj (350mm² cheeb tsam); ② Q355B {+0.8 hli carburizing (hrc50-55); Muaj ntau dua lossis sib npaug ntawm 90% haum. Cov Qauv: Tsawg dua lossis sib npaug rau 0.3mm tom qab kev hloov pauv / xyoo, tsawg dua lossis sib npaug nrog rau 23kn constrain, haum 25t ntau dua lossis sib npaug ntawm 600m nkhaus. Qhov tshwm sim: 0.1Mm hnav / xyoo (0.3 hli ua ntej).
- Yuav ua li cas los daws tau 0.5mm sib txawv ntawm txoj hlua khi hauv alpine (-40 degree) ntawm qhov yuav tsum tau ua yog dab tsi?
Tsawg kub ua rau qhov sib txawv. Kev ua kom zoo: ① 0.3mm nbr nyaj cov ntaub ntawv; ② Kev kho kom zoo (ntau dua lossis sib npaug rau 5N / hli adhesion); ③ 12 → 14kn preload. Yuav tsum muaj: tsawg dua los yog sib npaug rau 0.2mm sib txawv, ntau dua lossis sib npaug lossis sib npaug lossis sib npaug ntawm 5%, haum alpine 25t rail. Qhov tshwm sim: Peb lub hlis twg txij nkawm (txhua hli ua ntej).
- Cov Kev Tiv Thaiv Kev Nyab Xeeb / Canced ntsuas cov qauv / qauv rau khi khi, thiab yuav ua li cas los lis 320mpa kev ntxhov siab (tsawg dua lossis sib npaug ntawm 280mpa)?
Cov qauv xeem: ① siab -} rhiab zaj duab xis (± 5mpa); ② Meter ceeb ntsuas rau kev txwv; Goosate gauge rau kev sib tshuam. Cov Qauv: Tsawg dua lossis sib npaug ntawm 280MPA kev ntxhov siab, loj dua los yog sib npaug) / 20kn (Tsawg} temp) Constraint, Tsawg dua lossis sib npaug rau 0.2 hli sib txawv. Tuav: ① 50 → 52mm arc vojvoog; ② Polishing (ra tsawg dua lossis sib npaug rau 1.6μm); ③ Rov {{12} mus kuaj tsawg dua lossis sib npaug ntawm 280mpa.
- Dab tsi yog qhov kev ntxhov siab / kev cuam tshuam sib txawv rau khi phaj hauv kev sib txawv sib txawv (ncaj / nkhaus 800m) & qag lo lus, thiab muaj qag lo nrog mismatch?
Qhov sib txawv: ① Ncaj / 25T: tsawg dua los yog sib npaug nrog 300mpa kev ntxhov siab, loj dua los yog sib luag rau 18K constrain; Curved 800m / 25T: tsawg dua lossis sib npaug ntawm 280MPA kev ntxhov siab, loj dua los yog sib luag rau 23Kn txwv; Curved 600m / 30T: tsawg dua lossis sib npaug nrog 260mpa kev ntxhov siab, loj dua los yog sib npaug ntawm 28KK constraint. Miscatch: nkhaus 600m / 30t nrog khi ncaj phaj: 1.2mm tom qab kev hloov pauv / xyoo, 15% kev sib cav sib ceg, 350k tus nqi.
- Yuav ua li cas rau kev sib tw clip clamping force nrog khi phaj rau kev txwv daim ntawv, thiab ua li cas nrog kev sib txuam tsis zoo?
Kev txuam: ① 23kn insttraint (nkhaus 800m / 25T): 16KP lub zog; ② 28K constrain (nkhaus 600m / 30T): 18KP lub zog; ③ tsawg dua los yog sib npaug rau 0.3mm ntev / transverse kev hloov chaw. Cov Qauv: Tsawg dua lossis sib npaug ntawm 8% Clip yuam kev / xyoo, tsawg dua los yog sib npaug rau 5% kev sib luag rau 5% CALTRAFE DABNEEG / XYOO. Tsis zoo txuam: 28Nk txwv nrog 14kn lub clamp Force: 0.7 hli Longitudinal tsiv chaw / xyoo, 0.5 hli kev tsheb nqaj hlau, 25% txij nkawm.
