Leeb Hardness Tester
Tam sim no, lub tshuab ntsuas qhov nyuaj Leeb siv dav hauv kev sim qhov nyuaj ntawm cov khoom castings. Lub tshuab ntsuas qhov nyuaj Leeb siv lub hauv paus ntsiab lus ntawm kev sim qhov nyuaj dynamic thiab siv cov thev naus laus zis computer los ua kom lub tshuab ntsuas qhov nyuaj me me thiab hluav taws xob me me. Nws yooj yim thiab yooj yim siv, kev nyeem ntawv yooj yim dua, thiab cov txiaj ntsig ntawm kev xeem tuaj yeem hloov pauv mus rau hauv Brinell hardness tus nqi yooj yim, yog li nws tau txais tos dav dav.
Ntau cov castings yog cov workpieces nruab nrab mus rau loj, qee qhov hnyav ntau tons, thiab tsis tuaj yeem kuaj ntawm lub rooj ntev zaum saum toj kawg nkaus hardness tester. Qhov kev xeem hardness tseeb ntawm castings feem ntau siv cov cam khwb cia xeem rods lossis cov test blocks txuas rau castings. Txawm li cas los xij, tsis yog lub test bar lossis lub test block tuaj yeem hloov pauv tag nrho cov workpiece nws tus kheej. Txawm tias nws yog tib lub cub tawg ntawm cov hlau molten, cov txheej txheem casting thiab cov xwm txheej kho cua sov yog tib yam. Vim muaj qhov sib txawv loj heev ntawm qhov loj me, qhov ceev cua sov, tshwj xeeb tshaj yog qhov ceev txias, yuav txawv. Nws nyuaj rau ua kom ob qho tib si muaj tib qhov nyuaj. Vim li no, ntau tus neeg siv khoom mob siab rau thiab ntseeg qhov nyuaj ntawm cov workpiece nws tus kheej. Qhov no xav tau lub portable precision hardness tester los kuaj qhov nyuaj ntawm castings. Lub Leeb hardness tester daws qhov teeb meem no, tab sis nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov tiav ntawm qhov chaw ua haujlwm thaum siv Leeb hardness tester. Lub Leeb hardness tester muaj cov kev cai rau qhov roughness ntawm qhov chaw ua haujlwm.
Brinell Hardness Tester
Yuav tsum siv lub Brinell hardness tester rau kev sim qhov nyuaj ntawm cov castings. Rau cov hlau grey castings nrog cov nplej ntxhib, yuav tsum siv cov xwm txheej xeem ntawm 3000kg zog thiab 10 hli pob ntau li ntau tau. Thaum qhov loj me ntawm casting me me, Rockwell hardness tester kuj tseem siv tau.
Feem ntau cov hlau castings muaj cov qauv tsis sib xws, cov noob loj dua, thiab muaj ntau cov pa roj carbon, silicon thiab lwm yam tsis huv dua li hlau, thiab qhov nyuaj yuav sib txawv hauv ntau thaj chaw me me lossis ntawm ntau qhov chaw sib txawv. Lub indenter ntawm Brinell hardness tester muaj qhov loj dua thiab thaj chaw indentation loj dua, thiab tuaj yeem ntsuas qhov nruab nrab ntawm cov khoom siv hardness hauv qee qhov ntau. Yog li ntawd, Brinell hardness tester muaj qhov tseeb ntawm kev sim siab dua thiab kev sib kis me dua ntawm cov nqi hardness. Tus nqi hardness ntsuas tau yog tus sawv cev ntau dua ntawm qhov nyuaj tiag tiag ntawm qhov workpiece. Yog li ntawd, Brinell hardness tester yog siv dav hauv kev lag luam foundry.
Rockwell hardness
Cov cuab yeej ntsuas Rockwell hardness kuj tseem siv rau kev ntsuas qhov nyuaj ntawm cov hlau cam khwb cia. Rau cov khoom ua haujlwm nrog cov noob me me, yog tias tsis muaj thaj chaw txaus rau kev ntsuas Brinell hardness, kev ntsuas Rockwell hardness kuj tseem tuaj yeem ua tau. Rau cov hlau pearlitic malleable, cov hlau txias thiab cov hlau cam khwb cia, HRB lossis HRC nplai tuaj yeem siv. Yog tias cov khoom tsis sib npaug, yuav tsum ntsuas ntau zaus thiab tus nqi nruab nrab yuav tsum tau coj.
Ntug dej Hardness Tester
Hauv qee kis, rau qee qhov castings nrog cov duab loj, nws tsis raug tso cai txiav cov qauv, thiab nws tsis raug tso cai pov ntxiv cov thaiv kev sim rau kev sim qhov nyuaj. Lub sijhawm no, kev sim qhov nyuaj yuav ntsib teeb meem. Rau qhov xwm txheej no, txoj kev siv dav dav yog sim qhov nyuaj nrog lub cuab yeej Shore hardness tester portable ntawm qhov chaw du tom qab casting tiav. Piv txwv li, hauv tus qauv dov siv dav hauv kev lag luam metallurgical, nws tau teev tseg tias Shore hardness tester yuav tsum tau siv los sim qhov nyuaj.
