Los ntawm yam twg ua qhov ua tau zoo ntawm cov hlau stamping qhov cuam tshuam?
Hauv peb lub neej txhua hnub, cov hlau stamping qhov chaw nyob txhua qhov chaw. Txhawm rau txhawm rau txhim kho kev tsim khoom kom zoo thiab ua tau zoo ntawm cov neeg siv khoom, peb txuas ntxiv mus qhia txawv teb chaws thev naus laus zis thiab cov khoom lag luam. Hauv qhov twg yog qhov zoo ntawm cov hlau stamping qhov cuam tshuam? Txheeb xyuas los ntawm cov ntsiab lus hauv qab no:
1. Tshuaj tshuaj, tshuaj metallographic
Txheeb xyuas cov ntsiab lus ntawm cov tshuaj lom neeg hauv cov khoom, txiav txim siab qib loj npaum li cas thiab qhov sib xws ntawm cov khoom, ntsuas qib tsis pub dawb cementite, cov qauv tsim thiab cov tsis yog xim hlau suav nrog hauv cov khoom, thiab tshawb xyuas cov khoom' s shrinkage, porosity thiab lwm yam tsis xws luag.
2. Khoom tshuaj xyuas
Cov ntaub ntawv ua tiav los ntawm kev thim qhov feem ntau yog kub dov lossis txias-dov (feem ntau yog txias-dov) cov ntawv hlau. Cov ntaub ntawv raw ntawm cov hlau stamping qhov chaw yuav tsum muaj daim ntawv pov thawj zoo kom ntseeg tau tias cov ntaub ntawv ua tau raws li cov txheej txheem tshwj xeeb. Thaum tsis muaj daim ntawv pov thawj zoo lossis vim yog lwm qhov laj thawj, cov chaw tsim khoom lag luam hlau tuaj yeem xaiv cov ntaub ntawv raw rau kev tshuaj xyuas dua raws li xav tau.
3. Ua qhov kev xeem ua tau zoo
Ua qhov kev ntsuas khoov thiab ntsuas qhov ntsuas ntawm cov khoom, txiav txim siab qhov ua haujlwm hnyav ua haujlwm n tus nqi thiab cov yas sib piv piv r tus nqi ntawm cov khoom. Ib qho ntxiv, cov ntawv hlau tsim txoj kev ntsuas kev ua tau zoo tuaj yeem ua tiav raws li cov ntawv hlau nyias ua rau kev ua tau zoo thiab ntsuas cov qauv.
4. Kev xeem tawv
Qhov kev sim tawv ntawm cov hlau stamping qhov txais yuav Rockwell hardness tester. Cov khoom me me uas muaj cov duab nyuaj tuaj yeem siv los ntsuas lub dav hlau me me, tsis tuaj yeem kuaj ntawm lub desktop Rockwell hardness tester zoo ib yam.
5. Kev txiav txim siab txog lwm yam kev ua tau zoo
Kev txiav txim siab cov khoom siv hluav taws xob sib nqus ntawm cov khoom siv thiab cov nplaum rau plating thiab txheej.
Cov kev xav tau rau kev ua cov hlau stamping qhov chaw tau qhia rau txhua tus neeg ntawm no. Ib qho ntxiv, nws yuav tsum tau sau tseg tias qhov raug thiab qhov xwm txheej ntawm cov hlau kub stamping qhov chaw qis dua cov hlau txias stamping qhov chaw, tab sis tseem zoo dua li castings thiab zam txim, thiab qhov txiav yog tsawg dua.
