1.Dab tsi yog qhov zoo ntawm galvanized coil stamping?
Kev ua haujlwm tau raws li kev lag luam: Ib txheej txheem ua haujlwm ua haujlwm nyuaj, corrosion- tiv taus qhov chaw, tshem tawm cov kauj ruam thib ob ntawm stamping thiab galvanizing, txuag nqi thiab sijhawm.
Kev ua tau zoo ntawm cov khoom siv hauv paus: Cov khoom siv hauv paus yog tsim los ntawm cov hlau tshwj xeeb tsim rau kev sib sib zog nqus nqus, muab cov khoom zoo thiab tsim nyog rau deformation, xws li ncab thiab khoov.
2.Dab tsi yog cov teeb meem tshwm sim thaum stamping?
Zinc txheej peeling / hmoov: Nyob rau hauv lub tensile thiab extrusion teebmeem ntawm pwm, zinc txheej yuav tsim microcracks los yog txawm poob tawm ntawm lub substrate. Cov hmoov zinc detached yuav ua raws li cov pwm los yog ib feem ntawm qhov chaw, cuam tshuam qhov zoo thiab pwm lub neej.
Deg khawb: Yog hais tias cov pwm nto tsis du los yog muaj impurities, nws yuav khawb cov mos zinc txheej, cuam tshuam cov tsos thiab corrosion kuj ntawm qhov chaw.
Zinc slag sticking rau pwm: Cov hmoov zinc detached yuav sinter thiab ua raws li cov pwm nto nyob rau hauv qhov kub thiab txias siab, tsim ua - nce ntug, uas yuav ua rau khawb los yog puas tsuaj rau ntawm qhov chaw.
3.Dab tsi yog cov ntsiab lus tseem ceeb thaum stamping?
Zinc Peeling / Powder: Xaiv txoj cai galvanized kauj:
Txheej Txheej: Ntshiab zinc txheej yog nyiam. Nws muaj ductility zoo dua li zinc- hlau alloy txheej thiab tiv taus ntau dua rau stamping deformation.
Txheej Thickness: Xaiv cov txheej nyias nyias. Thicker coatings yog ntau raug rau tev. Xaiv cov qib xws li Z60 lossis Z90 raws li koj xav tau.
Surface Treatment: Xaiv cov ntaub ntawv uas muaj cov roj nplua nyeem los muab lubrication thiab txo kev sib txhuam.
Optimize Tuag Design:
Tsim nyog Die Gap: Qhov sib txawv yuav tsum yog me ntsis loj dua cov khoom tuab kom tso cai rau qhov chaw rau cov zinc txheej ntws thiab tiv thaiv kom tsis txhob muaj ntau dhau. Qhov sib txawv ntawm 110% mus rau 130% ntawm cov khoom thickness feem ntau pom zoo.
Lub kaum ntse ntse txaus: Lub kaum sab xis ntawm lub punch thiab tuag yuav tsum nyob nruab nrab kom tsis txhob muaj kev ntxhov siab thiab tso cai rau cov khoom siv zoo.
High Finish thiab Hardness: Cov tuag (tshwj xeeb tshaj yog cov drawbeads) yuav tsum tau polished thiab muaj ib tug siab hardness kom txo tau kev sib txhuam thiab zinc sticking. Txheej txheem tswj:
- Kev Siv Cov Lubricants Tshwj Xeeb: Txawm tias cov khoom siv roj, ntxiv cov roj nplua nyeem ntxiv yog qhov ua tau zoo heev rau txoj kev molding.
Nto khawb: Khaws cov pwm thiab cov khoom siv kom huv si.
Xyuas kom cov pwm saum npoo yog du.
Xyuas kom lub lubrication txaus.
Zinc dross sticking rau pwm: - Ntxuav thiab tswj cov pwm tsis tu ncua.
- Siv cov khoom siv los tiv thaiv- nplaum pwm los yog txheej.
- Ua kom zoo lubrication los ua ib qho thaiv.
4.Dab tsi yog qhov kev tiv thaiv-corrosion kev ua tau zoo tom qab stamping?
Microcracks yog ib txwm: Nyob rau hauv cov cheeb tsam ntawm khaus deformation, cov kab nrib pleb me me hauv zinc txheej yog qhov qub thiab feem ntau pom tsis pom ntawm qhov muag liab qab.
Kev tiv thaiv anodic tseem nyob ruaj khov: Zinc yog tshuaj lom neeg ntau dua li hlau. Nyob rau hauv lub xub ntiag ntawm electrolyte, txawm ib tug discontinuous zinc txheej yuav corrode ua ntej hlau, yog li tiv thaiv cov raug los yog ze li ntawm raug steel substrate. Qhov "sacrificial anodic" nyhuv no tshwj xeeb tshaj yog pom nyob rau hauv khawb thiab txiav.
Zuag qhia tag nrho kev tiv thaiv corrosion tseem zoo dua: Thaum lub corrosion kuj ntawm stamped cheeb tsam yog theoretically qis tshaj ntawm cov cheeb tsam tiaj tus, nws tseem yog qhov kev txiav txim ntawm qhov loj dua li ntawm ungalvanized stamped steel qhov chaw.
5.Dab tsi yog qhov khoom siv tau?
Kev Lag Luam Hauv Tsev: Lub tub yees, cua txias, thiab lub tshuab ntxhua khaub ncaws thiab cov khoom siv sab hauv.
Automotive Kev Lag Luam: Cov roj tso tsheb hlau luam, cov chassis me me, cov hlua khi, cov tsev nyob, thiab lwm yam (feem ntau siv cov hlau galvanized).
Computer Cases thiab Txee: Cov rooj plaub hauv computer, cov khoom sib txuas lus network, cov thawv hluav taws xob tswj, thiab lwm yam.
Kev Tsim Kho Kev Lag Luam: Cov kav dej, cov khoom sib txuas, cov hlua khi, thiab lwm yam.
