Hlau daim hlau yog dav siv nyob rau hauv structural manufacturing, architectural engineering, pipeline fabrication, automotive ntau lawm thiab mechanical processing. Hauv kev tsim khoom thiab kev siv tiag tiag, cov hlau phaj feem ntau raug khoov, folding thiab tsim cov txheej txheem. Qhov kev ua tau zoo ntawm kev khoov ncaj qha cuam tshuam txog cov khoom siv ductility, cov txheej txheem sab hauv cov qauv sib xws thiab lub ntsej muag toughness, uas yog qhov tseem ceeb rau kev txiav txim siab seb cov phaj hlau puas tsim nyog rau kev ua haujlwm theem nrab thiab cov txheej txheem kev teeb tsa. Txhawm rau kom ua tiav kev ua haujlwm ruaj khov thiab tsim nyog daim ntawv thov zoo ntawm cov hlau xa tawm, peb lub Hoobkas siv tus qauv thiab tag nrho -batch saib xyuassteel phaj dabtsi yog khoov kuajrau tag nrho cov khoom, nruj me ntsis tswj cov khoom zoo los ntawm qhov chaw.

1. Taw qhia rau Steel Phaj Bending Test

Cov hlau phaj dabtsi yog khoov kuaj yog ib qho tseem ceeb thiab qhov tseem ceeb ntawm cov khoom siv tshuaj ntsuam xyuas, uas lub hom phiaj txhawm rau txheeb xyuas cov yas deformation muaj peev xwm thiab kev ncaj ncees ntawm cov hlau phaj hauv qab khoov load. Tsis zoo li kev sim tensile thiab qaug zog uas tsom mus rau ntev - lub sij hawm lub zog thiab dynamic load tsis kam, qhov kev sim bending simulates lub txias dabtsi yog khoov thiab tsim tej yam kev mob ntawm steel daim hlau nyob rau hauv lub Hoobkas ua thiab nyob rau hauv - qhov chaw tsim.

Los ntawm kev quab yuam ntawm cov qauv mus rau lub kaum sab xis thiab lub vojvoog, peb pab pawg QC intuitively tshawb xyuas seb cov hlau phaj puas muaj cov khoom siv zoo heev thiab seb puas muaj qhov tsis zoo hauv cov khoom. Nws yog txoj kev tshawb pom ncaj qha tshaj plaws los ntsuas qhov kev ua tau zoo thiab kev ua haujlwm ntawm cov hlau phaj.

2. Kev Xeem Ua Haujlwm

Qhov kev sim khoov tau txais cov khoom siv khoov cov khoom siv los kho cov qauv hlau phaj ruaj khov. Raws li cov txheej txheem thoob ntiaj teb, cov ntawv xeem yog khoov rau lub kaum sab xis khoov (90℃/ 180 degree) thiab khoov txoj kab uas hla ntawm qhov ceev tsis tu ncua. Thaum lub sij hawm qhov kev xeem, txheej txheej ntawm dabtsi yog khoov seem yog raug rau tensile kev nyuaj siab, thiab lub puab txheej yog raug compressive kev nyuaj siab.

Yog hais tias cov hlau phaj muaj cov qauv sab hauv, tsim nyog ductility thiab ruaj khov, nws muaj peev xwm tswj tau tiav qhov kev ncaj ncees tom qab khoov. Nyob rau hauv sib piv, cov ntaub ntawv tsis tsim nyog uas tsis zoo ductility, ntau dhau ntawm impurities los yog cov yam ntxwv tsis xws luag yuav ua rau tawg, tawg thiab tev ntawm qhov chaw khoov. Los ntawm kev soj ntsuam lub xeev deformation thiab deg mob tom qab khoov, peb tuaj yeem txiav txim siab qhov zoo thiab qhov tsis zoo ntawm cov khoom siv steel phaj.

3. Cov khoom kuaj tseem ceeb thiab cov qauv tshuaj ntsuam xyuas

Peb cov hlau phaj dabtsi yog khoov kuaj tau ua raws li nruj raws li cov qauv thoob ntiaj teb tseem ceeb suav nrogISO 7438, ASTM A370 thiab GB / T 232, npog tag nrho cov lus qhia tshwj xeeb thiab kev cai siab - tus qauv yuav tsum tau ua rau cov khoom xa tawm:

3.1 Cold Bending Performance TestUa chav tsev-kub txias dabtsi yog khoov kuaj rau cov thicknesses sib txawv thiab qib steel ntawm steel phaj. Teem tus qauv dabtsi yog khoov radii thiab dabtsi yog khoov lub kaum ntse ntse kom simulate cov pa txias sib sau ua haujlwm. Tshawb xyuas qhov chaw thiab hla- ntu ntawm cov qauv khoov rau cov kab nrib pleb, fissures, delamination thiab lwm yam tsis xws luag, uas yog cov khoom tseem ceeb hauv kev soj ntsuam rau steel phaj kev tsim nyog.

3.2 Rov ua dua Bending TestRau cov hlau phaj siv rau ntau- tsim thiab rov ua haujlwm khoov dua tshiab, ua cov kev sim ntsuas kev sib hloov kho kom zoo los xyuas cov khoom siv los tiv thaiv- qaug zog dabtsi yog khoov. Kev soj ntsuam zoo ntawm cov qauv kev ruaj ntseg ntawm cov hlau phaj tom qab ntau yam deformations kom tsis txhob ua haujlwm tsis ua haujlwm thiab cov khoom seem thaum lub sijhawm ua haujlwm sib sib zog nqus.

3.3 Tag Nrho -Thickness Bending DetectionLub hom phiaj ntawm nruab nrab thiab tuab steel daim hlau rau cov qauv engineering, ua tiav -thickness dabtsi yog khoov kuaj txhawm rau txheeb xyuas qhov sib xws ntawm cov ntaub so ntswg ntawm cov phaj tuab. Tiv thaiv cov teeb meem tsis tsim nyog xws li kev ntxhov siab tsis sib xws thiab cov lamination sab hauv ua rau khoov tawg, ua kom muaj kev nyab xeeb tag nrho ntawm cov hlau phaj tuab.

4. Cov txheej txheem kuaj xyuas tus qauv

Txhawm rau kom ntseeg tau qhov tseeb, ua tau zoo thiab tshawb xyuas cov ntaub ntawv, peb lub Hoobkas tsim cov txheej txheem kaw ua tiav - voj dabtsi yog khoov cov txheej txheem:

Ua ntej, cov qauv qauv raug xaiv los ntawm txhua pawg ntawm cov hlau tiav los xyuas kom meej cov qauv sawv cev. Ua ntej qhov kev xeem, cov qauv saum npoo yog polished thiab ntxuav kom tshem tawm cov kev cuam tshuam ntawm burrs thiab impurities ntawm qhov kev xeem. Cov cuab yeej raug ntsuas ua ntej txhua qhov kev xeem kom lav qhov ntsuas qhov tseeb.

Thaum lub sij hawm xeem, qhov khoov ceev thiab lub kaum sab xis yog nruj me ntsis tswj raws li tus qauv specifications. Tom qab qhov khoov tiav lawm, cov kws tshuaj ntsuam xyuas tau ua qhov kev soj ntsuam macroscopic thiab tshuaj xyuas cov ncauj lus kom ntxaws ntawm qhov khoov arc nto, ntug thiab ntoo khaub lig-section. Txhua qhov kev xeem tau raug kaw nyob rau lub sijhawm tiag tiag, thiab cov ntawv tshaj tawm kev xeem tau raug muab sib npaug. Cov khoom tsis tsim nyog yuav raug cais tawm tam sim ntawd, rov- tshuaj xyuas thiab tsis lees paub kom ntseeg tau tias tsis muaj khoom xa tuaj.

5. Kev ntsuam xyuas qhov tseem ceeb thiab cov khoom zoo

Kev kuaj khoov yog qhov kev soj ntsuam zoo tshaj plaws rau tus qauvkev ua tau zoo ntawm steel phaj. Cov phaj hlau uas dhau qhov kev ntsuas nruj nruj muaj cov yas zoo ductility, cov qauv sab hauv thiab muaj zog ua kom haum, uas tuaj yeem hloov kho rau ntau yam txias khoov, folding, dov thiab sib sib zog nqus cov txheej txheem.

Hauv kev siv engineering tiag tiag, kev ua tau zoo khoov tau zoo tuaj yeem zam cov teeb meem kev tsim kho xws li phaj tawg thiab ntug kev puas tsuaj thaum ua, txo cov khoom seem thiab cov nqi tsim kho, thiab txhim kho kev ua tau zoo thiab ua tiav cov khoom zoo ntawm cov neeg siv khoom. Peb cov ntawv hlau xa tawm tau ruaj khov kho tau zoo thiab kev ua haujlwm zoo, uas tau lees paub dav hauv kev tsim kho thoob ntiaj teb, kev tsim khoom siv, steel qauv thiab lwm yam lag luam.

6. Kev cog lus zoo

Peb ib txwm coj cov qauv kev ntsuas kev ua tau zoo raws li qhov yooj yim lav ntawm steel phaj zoo. Kev ntsuas dabtsi yog khoov, uas yog ib qho tseem ceeb ntawm cov khoom soj ntsuam rau kev ua haujlwm ntawm steel phaj, yuav tsum ua tsis tu ncua nyob rau hauv tag nrho -batch zoo tswj. Nrog rau cov qauv kev ntsuam xyuas meej thiab cov txheej txheem tshuaj xyuas nruj, peb xyuas kom meej tias txhua pawg ntawm cov hlau xa tawm tau zoo heev, ruaj khov thiab txhim khu kev qha ua tau zoo, muab siab - zoo thiab siab - tus nqi steel raw khoom rau cov neeg siv khoom thoob ntiaj teb.
