Cov Txheej Txheem Caij Nyoog Txog Cov Hlau Fabrication - Hlau Tawv Ua (4)
5. Ua Hlau
5.1 Kev Sib Hlau - Ntxiv Dag Ntxiv
Nias zog tuaj rau ntawm qhov chaw ntawm hlau yuav pab txhawb kev ua kom muaj kev ruaj ntseg, muaj zog dua. Saib Daim Ntawv 6 ntawm qhov kev xaiv me me.
Cov lus 6 Cov qauv ntawm kev pabcuam reinforcement thiab nws qhov kev xaiv loj
5.2 Hlau Tsim - Hloov Cov Hnyav Nres
Limiting dimension rau nruam thiab ntug nrug ntawm nruab nrab ntawm qhov chaw hla kev
Kos rau nram qab lub rooj rau limiting dimension.
Table 7 Limiting dimension rau kev sib kis thiab ntug nrug ntawm nruab nrab ntawm kev sib xyaw convex
5.3 Kev Sib Tham Hlau - Louvers
Louvers feem ntau yog siv rau qhov cua thiab cua kub cev rau ntau lub tsev los yog chassis.Qhov kev ua tus qauv yog txiav cov khoom los ntawm ib tug ntug ntawm cov punch, hos so ntawm lub punch yuav ncab thiab deform cov khoom tib lub sijhawm.
Tus qauv ntawm lub louver yog qhia nyob rau hauv daim duab 6.3.1.
Daim duab 6.3.1 ua tus qauv ntawm lub louvers
Kev tsim nyog rau qhov louvers me me: ib tug = 4t; b≥6t; h≤5t; L≥24t; r≥0.5t.
5.4 Hlau Kev: Lub qhov flanging
Muaj ntau hom ntawm qhov flanging. Qhov kev qhia tshwj xeeb no tsuas yog siv rau ntawm lub qhov flanging rau cov zauv xov, raws li muaj nyob hauv daim duab 6.4.1.
Daim duab 6.4.1 kos duab ntawm sab hauv lub qhov flanging qauv nrog threaded qhov
Cov lus 8 tsis muaj qhov sib npaug ntawm sab hauv flanging nrog threaded qhov
