Lub tshuab ntsuas tawv Rockwell superficial yog ib hom tshuab ntsuas tawv Rockwell. Nws siv lub zog me dua. Thaum kuaj qee cov khoom me me thiab nyias, kev siv lub tshuab ntsuas tawv Rockwell yuav ua rau cov nqi ntsuas tsis raug. Peb tuaj yeem siv lub tshuab ntsuas tawv Rockwell superficial. Lub tshuab ntsuas tawv kuj tseem siv tau los ntsuas cov khoom ua haujlwm nrog cov txheej tawv tawv Superficial.
Nws txoj cai xeem zoo ib yam li Rockwell hardness tester. Qhov txawv yog tias lub zog xeem pib yog 3KG, thaum lub zog xeem pib ntawm Rockwell hardness tester yog 10KG.
Lub zog ntsuas ntawm lub zog Rockwell hardness ntawm lub tshuab kuaj: 15KG, 30KG, 45KG
Tus indenter siv rau hauv Superficial Rockwell hardness tester yog sib xws nrog Rockwell hardness tester.:
1. 120 hnubegrade pob zeb diamond cone indenter
2. 1.5875 hlau pob indenter
Rockwell saum npoo avhardness tester ntsuas qhov ntsuas:
HR15N, HR30N, HR45N, HR15T, HR30T, HR45T
(Qhov ntsuas N yog ntsuas los ntawm lub pob zeb diamond indenter, thiab qhov ntsuas T yog ntsuas los ntawm lub pob hlau indenter)
Qhov hardness yog qhiaxws li: qhov nyuaj ntxiv rau Rockwell nplai, piv txwv li: 70HR150T
15T txhais tau tias lub pob hlau indenter nrog tag nrho lub zog sim ntawm 147.1N (15 kgf) thiab lub indenter ntawm 1.5875
Raws li cov lus qhia saum toj nokev tshawb fawb txog kev ua vaj tse, Superficial Rockwell muaj cov txiaj ntsig zoo li nram no:
1. Vim nws muaj oblub taub hau siab, nws tsim nyog rau cov ntaub ntawv hlau mos thiab tawv.
2. Lub zog sim yog smaller dua li ntawm Rockwell hardness tester, thiab qhov kev puas tsuaj ntawm qhov workpiece yog me heev.
3. Qhov kev sim me mee tuaj yeem hloov ib feem ntawm Vickers hardness tester, uas yog tus nqi pheej yig thiab pheej yig.
4. Cov txheej txheem sim yog ceev thiab cov khoom ua tiav tiav tuaj yeem kuaj pom tau zoo.
