I-Leeb Hardness Tester
Okwangoku, i-Leeb hardness tester isetyenziswa ngokubanzi kuvavanyo lobulukhuni bokuphosa.Umvavanyi wobulukhuni be-Leeb wamkela umthetho-siseko wokuvavanya ubulukhuni obuguquguqukayo kwaye usebenzisa itekhnoloji yekhompyuter ukuqonda i-miniaturization kunye ne-elektroniki yomvavanyi wobulukhuni.Kulula kwaye kulula ukuyisebenzisa, ukufundwa kunomdla ngakumbi, kwaye iziphumo zovavanyo zinokuguqulwa ngokulula zibe ngamaxabiso obunzima beBrinell, ngoko ke yamkelwa ngokubanzi.
Iicastings ezininzi ziphakathi ukuya kwezinkulu, ezinye zazo ezinobunzima beetoni ezininzi, kwaye azinakuvavanywa kwi-bench-top hardness tester.Uvavanyo oluchanekileyo lobulukhuni bokuphosa ubukhulu becala kusetyenziswa iirodi zokuvavanya ngokwahlukeneyo okanye iibhloko zovavanyo ezincanyathiselwe kwi-castings.Nangona kunjalo, akukho bha yovavanyo okanye ibhloko yovavanyo inokutshintsha ngokupheleleyo indawo yokusebenza ngokwayo.Nangona isithando somlilo esifanayo sentsimbi etyhidiweyo, inkqubo yokuphosa kunye neemeko zonyango lobushushu ziyafana.Ngenxa yomahluko omkhulu ngobukhulu, izinga lokushisa, ngakumbi izinga lokupholisa, liya kuba lihluke.Kunzima ukwenza ezi zimbini zibe nobulukhuni obufanayo kanye.Ngesi sizathu, abathengi abaninzi bakhathalele ngakumbi kwaye bakholelwa kubunzima bomsebenzi ngokwawo.Oku kufuna umvavanyi wobulukhuni ochanekileyo ophathwayo ukuvavanya ubulukhuni bokuphosa.Umhloli wobulukhuni be-Leeb uyisombulula le ngxaki, kodwa kuyimfuneko ukunikela ingqalelo ekugqityweni komphezulu we-workpiece ngexesha lokusetyenziswa kwe-Leeb hardness tester.Umvavanyi wobulukhuni beLeeb uneemfuno zokurhabaxa komphezulu wesixhobo sokusebenza.
Brinell Hardness Tester
I-Brinell tester yokuqina kufuneka isetyenziswe kuvavanyo lobulukhuni bokuphosa.Ngokuphoswa kwentsimbi engwevu ngeenkozo ezirhabaxa noko, iimeko zovavanyo lwamandla angama-3000kg kunye nebhola eyi-10mm kufuneka zisetyenziswe kangangoko.Xa ubungakanani bokuphosa buncinci, i-Rockwell hardness tester nayo ingasetyenziswa.
I-iron castings ngokuqhelekileyo inesakhiwo esingalinganiyo, i-grains enkulu, kwaye iqulethe i-carbon eninzi, i-silicon kunye nezinye izinto ezingcolileyo kunentsimbi, kwaye ubunzima buya kuhluka kwiindawo ezincinci okanye kwiindawo ezahlukeneyo.I-indenter ye-Brinell hardness tester inobukhulu obukhulu kunye nendawo enkulu yokuhlenga, kwaye inokulinganisa ixabiso eliphakathi lobunzima bezinto eziphathekayo ngaphakathi koluhlu oluthile.Ke ngoko, umvavanyi wobulukhuni beBrinell unovavanyo oluchanekileyo kunye nokusasazwa okuncinci kwamaxabiso obunzima.Ixabiso lobunzima obulinganisiweyo limele ngakumbi ubulukhuni bokwenene bomsebenzi.Ke ngoko, i-Brinell hardness tester isetyenziswa kakhulu kwishishini le-Foundry.
Ubunzima beRockwell
Abavavanyi bobulukhuni be-Rockwell nabo baqhele ukusetyenziselwa uvavanyo lobulukhuni bentsimbi.Kwizixhobo zokusebenza ezineenkozo ezicolekileyo, ukuba akukho ndawo yaneleyo yovavanyo lobulukhuni beBrinell, uvavanyo lobulukhuni beRockwell nalo lunokwenziwa.Kwintsimbi etyhidiweyo ethambileyo yepearlitic, intsimbi ekhandisiweyo kunye neesanti zentsimbi, iHRB okanye isikali seHRC singasetyenziswa.Ukuba izinto eziphathekayo azikho Ngokulinganayo, ufundo oluninzi kufuneka lulinganiswe kwaye ixabiso eliphakathi kufuneka lithathwe.
Shore Hardness Tester
Kwiimeko zomntu ngamnye, kwezinye ii-castings ezineemilo ezinkulu, akuvumelekanga ukusika isampuli, kwaye akuvumelekanga ukuphosa iibhloko zovavanyo ezongezelelweyo zokuvavanya ubulukhuni.Ngeli xesha, uvavanyo lokuqina luya kudibana nobunzima.Kule meko, indlela eqhelekileyo kukuvavanya ubulukhuni kunye ne-portable Shore hardness tester kwindawo egudileyo emva kokuba ukuphosa kugqityiwe.Umzekelo, kumgangatho wokuqengqeleka osetyenziswa kakhulu kwishishini lesinyithi, kuchaziwe ukuba i-Shore hardness tester isetyenziselwe ukuvavanya ubulukhuni.
