Sheet hlau dabtsi yog khoov
Nyob hauv txoj kev tiaj tiaj hauv daim hlau, ua rau qhov kev cuam tshuam ntawm kev ua tiav ntawm qhov ntev ntev yog: khoov rau sab hauv r, qhov dav ntawm sab pwm (V-shaped groove), cov thickness ntawm cov ntaub ntawv t, thiab tho lub kaum sab xis. Thaum xam xyuas qhov ntev ntawm cov ntawv xov nplooj, nws tsis muaj qhov qhia tau meej txog kev thim nyiaj, thiab tsuas yog kev pabcuam dabtsi ntawm kev sib txawv hauv kev siv hluav taws xob sab nraud tuaj yeem pom tau tias.Tab sis lub voos kheej-kheej nyob ntawm kev ua haujlwm. Vov dav dav V-dav dav ntawm qhov siab ploj tuag yuav ua rau qhov sib txawv ntawm sab hauv lub vojvoog, uas ua tsis paub txiav txim qhov tseeb ntawm qhov nyiaj pabcuam dabtsi. Qhov kev pabcuam dabtsi yog txiavtxim siab rau feem ntau.
Nyob rau hauv cov hlau phoov, peb nquag siv L, N, thiab Z khoov. Peb yuav tham txog peb txoj kev sib tw nram qab no:
L Dab teg
L quav: 90 degree quav thiab tsis yog 90 degree qib.
● Qee qhov xaus ntawm 90 degree tshaj hauv Daim Ntawv 1:
L = A + B-Nyiaj pub dawb
L = A + B + 0.25 (2 * Π * r) {0.25 (2 * Π * r) qhov loj ntawm qhov nruab nrab}
● Tsis muaj 90 degree qib:
L = A + B + Compensation ★ tsuas yog siv rau
T = 0.8 R = 0.5, 120 ° ≤q≤160 °, Txhaum yog 0.1
160 °
T = 1.0 R = 0.5
120 ° ≤q≤145 °, Txhaum yog 0.2
145 °
170 °
T = 1.2 R = 0.5, Nyiaj Them Nqi T = 1.0
T = 1.5 R = 0.5, 120 ° ≤q≤130 °, Txhaum yog 0.3
130 °
150 °
170 °
180 ° -qq
L = A + B + - (2 * Π * r)
360 °
N Bending
N fold (Xa rov quav):
L = A + BC
Tsis kiag li rov qab quav (nthuav tawm los ntawm kev siv nruab nrab)
L = A + B + C, C = 0.5 (2 * Π * R )
Z Bending
Z tshooj xaus:
L = A + K
Lus cim: tom qab txuas nrog nyiaj them rau Z phaj (Tsab Ntawv 2)
* Kev ntsuas tus nqi K rau H qhov siab tsis tau teev nyob rau Tsab Ntawv 2 yuav muab xam raws li peb muaj.
Piv txwv: T = 1.2, H = 1.4;
Vim H nqis (1.3) yog nruab nrab ntawm 1.0 mus rau 1.5, ces K = (0.25-0.13) / 5*3+0.13, K = 0.2
Nco Ntsoov:
1. Thaum H value (HT)
2. Thaum H (HT) H (HT) ≥V / 2 + 1.5 (ib theem me zis me zis raws li cov ntaub thickness), peb yuav khoov sab nraub sab ces tom qab sab nraud.
3. Thaum L tus nqi
4.Thaum ua l tus nqi> V / 2 + 1.5, peb yuav khoov sab nraud thiab sab nraud ntawm nplooj ntawv.
