Cov txheej txheem txiav rau Galvanized Steel Phaj
Txiav yog thawj kauj ruam hauv feem ntau galvanized steel phaj fabrication txheej txheem. Cov lus hauv qab no qhia txog kev txiav cov txheej txheem rau cov thicknesses sib txawv:
| Thickness Ntau | Pom zoo txiav txoj kev | Key Parameters | Qhov zoo |
|---|---|---|---|
| 0.3-2.0 hli | Shearing (guillotine) | Shear ceev: 100-150mm / s; Clearance: 5-10% ntawm thickness | Ceev ceev, huv si txiav, tsis muaj cua sov puas rau txheej |
| 2.0-6.0 hli | Plasma txiav | Tam sim no: 30-60A; Txiav ceev: 500-800mm / min | High precision, haum rau cov duab complex |
| 6.0-12.0 hli | Oxy- txiav roj | Oxygen siab: 0.5-0.8MPa; Preheat lub sij hawm: 5-10s | Tus nqi qis, haum rau cov phaj tuab |
| Tag nrho cov thickness | Laser txiav (CNC) | Lub zog: 500-1500W; Ceev: 300-1000mm / min | Qhov siab tshaj plaws (kev ua siab ntev ± 0.1mm), tsis muaj burrs |
Txiav Cov Lus Qhia los Tiv Thaiv Zinc Txheej:
Siv cov cuab yeej ntse: Plua plav txiab los yog cov hniav ua rau txheej txheej txheej - hloov cov cuab yeej thaum txiav cov npoo qhia burrs.
Tswj cov cua sov nkag: Rau thermal txiav (plasma, oxy- roj), siv qhov tsawg kawg nkaus tsim nyog cua sov kom tsis txhob zinc evaporation (uas ua rau porosity nyob rau tom qab vuam).
Ntxuav cov npoo: Tshem cov zinc dross los ntawm kev txiav cov npoo nrog txhuam txhuam- qhov no ua kom cov vuam zoo thiab tiv thaiv corrosion.
Bending thiab Forming Techniques rau Galvanized Steel Phaj
Khoov thiab sib sau yog ib qho tseem ceeb rau shaping galvanized steel daim hlau rau hauv cov khoom xws li brackets, thav duab, thiab panels. Qhov tseem ceeb yog kom tsis txhob txheej txheej tawg thiab xyuas kom meej qhov tseeb.
Pom zoo Bending Parameters (rau S280GD galvanized steel daim hlau):
| Thickness (t) | Yam tsawg kawg nkaus Khoov Radius | Khoov ceev | Kub | Bending Direction |
|---|---|---|---|---|
| 0.5 hli | 0.5t (0.25 hli) | 5-10mm / s | Chav ntsuas kub | Txhua qhov kev taw qhia |
| 1.0 hli | 1t (1.0 hli) | 5-10mm / s | Chav ntsuas kub | Txhua qhov kev taw qhia |
| 2.0 hli | 1.5t (3.0 hli) | 3-8mm / s | Chav ntsuas kub | Tawm tsam dov kev taw qhia: 2t |
| 3.0mm ib | 2t (6.0 hli) | 3-5mm / s | Chav ntsuas kub | Tawm tsam dov kev taw qhia: 2.5t |
Khoov Tswv Yim:
Siv cov coated tuag: Roj hmab los yog yas-coated dabtsi yog khoov tuag tiv thaiv zinc txheej khawb-txo tuag hnav thiab txhim kho nto zoo.
Tsis txhob dhau - dabtsi yog khoov: Tshaj- dabtsi yog khoov (tshaj ntawm cov khoom siv elastic txwv) ua rau kev deformation mus tas li thiab txheej txheej tawg - kuaj ntawm cov qauv ua ntej.
Ncej - kev tshuaj xyuas khoov: Txheeb xyuas cov kab nrib pleb nrog lub iav tsom iav (10x) tom qab khoov- kho cov kab nrib pleb nrog zinc- nplua nuj xim.
Welding Techniques rau Galvanized Steel Phaj
Vuam galvanized steel daim hlau yuav tsum tau saib xyuas tshwj xeeb kom tsis txhob muaj zinc vapor porosity thiab tswj kev tiv thaiv corrosion. Cov hauv qab no yog cov kev pom zoo welding:
Gas Metal Arc Vuam (GMAW/MIG)
Hom hlau: ER70S-6 (mild steel hlau) los yog ER70S-G (galvanized steel-specific hlau)
Tiv thaiv roj: 90% Ar + 10% CO₂ (txo qis thiab porosity)
Parameters (rau 2.0mm thickness):
Tam sim no: 90-110A
Lub hwj chim: 19-21V
Ceev: 30-40cm / min
Qhov zoo: High vuam ceev, tsis tshua muaj cua sov input, tsawg zinc evaporation
Resistance Spot Welding (RSW)
Hom hluav taws xob: Tooj-chromium-zirconium (resist zinc adhesion)
Parameters (rau 1.5mm thickness):
Tam sim no: 9-12kA
Sijhawm: 0.2-0.3s
Siab: 3-5kN
Qhov zoo: Zoo tagnrho rau nyias daim hlau (0.5-3.0mm), tsis xav tau cov khoom muab tub lim
Vuam tswv yim los tiv thaiv cov teeb meem tshwm sim:
Ntxuav qhov chaw vuam: Tshem cov zinc txheej los ntawm thaj chaw weld (10-15mm ntawm txhua sab) nrog cov txhuam hlau-qhov no txo cov zinc vapor porosity.
Siv pulsed vuam: Pulsed GMAW txo cov cua sov nkag, txo cov zinc evaporation thiab spatter.
Tom qab -welding kev kho mob: Sib tsoo cov hlaws hlaws du thiab kov nrog zinc-nplua nuj xim kom rov ua kom corrosion.
Ventilate cheeb tsam: Zinc vapor yog teeb meem - kom muaj qhov cua zoo thaum vuam los tiv thaiv cov neeg ua haujlwm.
Stamping thiab sib sib zog nqus kos rau galvanized hlau daim hlau
GNEE Steel's galvanized steel daim hlau (tshwj xeeb tshaj yog DX53D + Z thiab S220GD + Z qib) yog qhov zoo tagnrho rau stamping thiab kos duab sib sib zog nqus- cov txheej txheem ntau hauv cov khoom siv hauv tsev thiab kev tsim tsheb.
Pom zoo Stamping Parameters:
- Lubrication: Siv dej- cov roj nplua nyeem (tsis txhob roj- cov roj nplua nyeem uas nyuaj los ntxuav) kom tsis txhob muaj kev sib txhuam thiab tiv thaiv cov txheej txheem puas.
- Blank tuav quab yuam: 10-15% ntawm cov khoom yield zog (xws li, 30-45kN rau S280GD, 1.0mm thickness).
- Daim duab nrawm: 50-100mm / s (slower rau sib sib zog nqus draws kom tsis txhob wrinkling).
- Tuag vojvoog: Yam tsawg kawg tuag vojvoog=2-3x cov khoom tuab (tiv thaiv txheej txheej tawg).
Kev kos duab sib sib zog nqus (rau DX53D + Z):
| Thickness | Qhov siab tshaj plaws kos duab piv (qhov tob / txoj kab uas hla) | Yam khoom tsim nyog |
|---|---|---|
| 0.3mm ib | 0.8:1 | Cov khob me me, ntxhua khaub ncaws |
| 0.5 hli | 0.6:1 | Fridge inner liners |
| 1.0 hli | 0.4:1 | Lub tshuab ntxhua khaub ncaws |
Stamping tswv yim:
- Siv polished tuag: Highly polished tuag (Ra Tsawg dua los yog sib npaug rau 0.8μm) txo kev sib txhuam thiab xyuas kom meej qhov chaw du ntawm qhov chaw stamped.
- Tswj qhov kub thiab txias: Khaws qhov khoob ntawm 20-30℃-cold temperatures txo formability, thaum kub kub ua rau lubricant tawg.
- Tshawb xyuas qhov tsis xws luag: Tshawb xyuas cov txheej tev tawm, wrinkling, los yog tawg tom qab stamping - kho qhov tsis xws luag yog tias muaj teeb meem tshwm sim.
