Yuav ua li cas txheeb xyuas qhov hardness ntawm Hex taub hau Drilling Screw

1. Rockwell hardness kuaj
Lub hauv paus ntsiab lus thiab kev ua haujlwm: Rockwell hardness test yog ib qho kev siv hardness test method. Nws siv lub pob zeb diamond cone los yog steel pob indenter los nias lub indenter rau hauv cov ntsia hlau nto nyob rau hauv ib qho kev sim quab yuam, thiab tom qab ntawd txiav txim siab tus nqi hardness raws li qhov tob ntawm indentation. Piv txwv li, rau HRC (Rockwell Hardness C Scale) kev xeem, thawj zaug kev xeem quab yuam yog siv ua ntej, ces lub ntsiab xeem quab yuam yog siv, thiab ces lub ntsiab xeem quab yuam raug tshem tawm, qhov seem seem indentation qhov tob yog ntsuas, thiab hardness tus nqi. yog xam.
Scope ntawm daim ntawv thov thiab raug: Txoj kev no yog tsim rau Hex Lub taub hau Drilling Screws nrog hardness siab dua, xws li carbon steel los yog alloy steel screws tom qab kev kho cua sov xws li quenching. Nws muaj qhov ntsuas qhov tseeb siab, tuaj yeem tau txais cov ntaub ntawv hardness sai thiab raug, thiab tuaj yeem kuaj ntawm qhov sib txawv ntawm cov ntsia hlau los ntsuas qhov sib xws ntawm tag nrho hardness.
2. Brinell hardness kuaj
Lub hauv paus ntsiab lus thiab kev ua haujlwm: Brinell hardness test siv lub pob carbide ntawm ib txoj kab uas hla mus rau hauv cov ntsia hlau nto nyob rau hauv ib qho kev xeem quab yuam, thiab tom qab ib lub sij hawm ntawm lub sij hawm, lub indentation txoj kab uas hla yog ntsuas, thiab hardness tus nqi yog xam raws li lub sij hawm. tus qauv. Thaum kuaj lub taub hau Hex Drilling Screw, nws yog ib qho tsim nyog los xaiv qhov tsim nyog xeem quab yuam thiab indenter txoj kab uas hla raws li cov khoom thiab xav tau hardness ntawm cov ntsia hlau.
Scope ntawm daim ntawv thov thiab raug: Brinell hardness test yog haum rau cov screws uas tsis tshua muaj hardness, xws li cov pa roj carbon steel zoo tib yam screws uas tsis tau kho cua sov. Nws qhov zoo dua yog tias cov txiaj ntsig kev xeem no kuj yog qhov tseeb thiab ruaj khov, tab sis vim tias nws yuav tawm hauv qhov loj me ntawm cov ntsia hlau, nws yuav muaj qee yam cuam tshuam rau cov tsos thiab kev ua haujlwm ntawm cov ntsia hlau, yog li yuav tsum tau ceev faj thaum xaiv cov ntsia hlau. qhov chaw kuaj.
3. Vickers hardness kuaj
Lub hauv paus ntsiab lus thiab kev ua haujlwm: Vickers hardness test yog siv lub pob zeb diamond tetrahedral tsis tu ncua nrog lub kaum sab xis ntawm 136 degree los nias rau hauv cov ntsia hlau nto nyob rau hauv qhov kev txiav txim ntawm lub zog ntsuas. Tom qab khaws cia rau ib lub sij hawm teev, kab pheeb ces kaum ntev ntawm lub indentation yog ntsuas thiab hardness tus nqi yog tau los ntawm kev xam. Thaum lub sij hawm xeem, nws yog ib qhov tsim nyog los xaiv qhov tsim nyog xeem quab yuam raws li qhov loj thiab hardness ntau yam ntawm cov ntsia hlau.
Scope ntawm daim ntawv thov thiab raug: Vickers hardness test yuav siv tau rau Hex taub hau Drilling Screws ntawm ntau yam ntaub ntawv, tshwj xeeb tshaj yog rau cov me me screws los yog cov xwm txheej uas yuav tsum tau muaj tseeb hardness ntsuas. Nws tuaj yeem ntsuas qhov nyuaj ntawm cov txheej txheej nyias nyias los yog qhov chaw me me nrog qhov raug siab, tab sis cov txheej txheem kev sim yog qhov nyuaj thiab siv sijhawm ntev.
