Isikhokelo seNyathelo elinye sokukhetha uhlobo olufanelekileyo
Khetha ngokusekelwe kwiimilinganiselo ezintlanu: ubungakanani bezinto zokusebenza, izinto ezisetyenzisiweyo, uluhlu lobunzima, iimfuno zokuchaneka, kunye neemeko zokusetyenziswa. Akukho mfuneko yokukhathazeka, landela nje isikhokelo kwaye ungenza isigqibo.
I. Okokuqala, yahlulahlula ibe ziintlobo ezintathu eziphambili zabavavanyi bobulukhuni
1. Rockwell Hardness Tester (HRC/HRB/HRA)
Ifanelekile: intsimbi ecinyiweyo, intsimbi eyomileyo, iibheringi, izixhobo, iindawo eziphathwa ngobushushu
Iingenelo: ukuchaneka okuphezulu, kusetyenziswa kakhulu kwimigangatho yesizwe, izixhobo ezisemgangathweni zokuhlolwa komgangatho wefektri
Izinto ezingalunganga: kufuneka uthathe iisampulu / uhlobo lwedesktop, iindawo ezinkulu azinakushukunyiswa okanye zivavanyelwe kwindawo
Oko kufuneka ukulinganiswe:
I-HRC: intsimbi eqinileyo neqinileyo (iidayi, izixhobo, iigiya)
I-HRB: ubhedu, i-aluminium, intsimbi ekhabhoni ephantsi, intsimbi ethambileyo
2. Isivavanyeli soBulukhuni beBrinell (HB)
Ifanelekile: isinyithi esityhidiweyo, isinyithi esityhidiweyo, i-aluminium alloy, i-copper alloy, iindawo ezirhabaxa ezenziwe ngesinyithi
Iingenelo: ukutsalwa okukhulu, okuchanekileyo kakhulu kwizinto ezirhabaxa nezingafaniyo
Iingxaki: ukutsalwa okukhulu, ukutshabalalisa, ukusebenza okuphantsi, okufanelekileyo ekuhlolweni kweendawo zelebhu
3. I-Leeb Hardness Tester (i-HL ephathekayo ukuya kwi-HRC/HB/HV)—YY251D Leeb Ubunzima Tester
Ifanelekile: iindawo ezinkulu, uvavanyo olukwindawo, iindawo ezingenako ukuqhekeka, iimold ezinzima, imiqulu, imingxunya
Iingenelo: iphathwa ngesandla kwaye iyaphatheka, ayitshabalalisi, akukho mfuneko yokuthatha iisampulu, ingasetyenziswa kwiindawo ezithe nkqo, ezithe tye, okanye eziphezu kwentloko
Iingxaki: ukuchaneka okuphantsi kancinci kune-desktop Rockwell, iimpazamo ezinkulu kwiindawo ezincinci nezincinci
II. Khetha ngokusekelwe kwiimeko zesicelo (ezona zisebenzayo)
Imeko 1: ilabhoratri yeworkshop, uhlolo lomgangatho wezinto ezingenayo / unyango lobushushu, ukuchaneka okuphezulu kuyadingeka Khetha isixhobo sokuvavanya ubulukhuni seRockwell kwidesktop
Ikhethwa kakhulu kwiifektri zezixhobo eziqhelekileyo, ezokwakha iidayi, nezokulungisa ubushushu.
Imeko yesi-2: isinyithi esibunjiweyo, izinto ezibunjiweyo, i-aluminium alloy, iindawo ezibunjiweyo ezingacacanga
Khetha isixhobo sokuvavanya ubulukhuni beBrinell
Imeko 3: iindawo ezinkulu ezingenakushukunyiswa, uvavanyo olukwindawo, iimolds/rolls/i-shafts ezinkulu Kufuneka ukhethe isixhobo sokuvavanya ubunzima beLeeb esiphathwayo
Imeko 4: iinxalenye ezincinci, amaphepha amancinci, ubulukhuni bomphezulu weeleya ezifakwe i-carburised kunye ne-nitrided Khetha isixhobo sokuvavanya ubulukhuni beVickers (HV)
Ifanelekile: amaphepha amancinci, imiphetho yezixhobo, iingubo, iileya eziqinileyo.
III. Khetha ngokusekelwe kubukhulu/ubungakanani bezinto zokusebenza
Iindawo ezinkulu, ezinzima, nezingenakushukunyiswa → Leeb
Iisampuli eziqhelekileyo, iinxalenye ezincinci, zingafakwa kwi-desktop → Rockwell
Iindawo ezincinci < 3mm, iileya eziqinileyo zomphezulu → IiVickers
Izinto ezingenanto zokuphosa, izinto ezingafanelaniyo → Brinell
IV. Khetha ngokusekelwe kwinqanaba lobulukhuni
Izixhobo ezithambileyo: i-aluminium, ubhedu, intsimbi ekhabhoni ephantsi → HRB / HB
Ubulukhuni obuphakathi: intsimbi ecinyiweyo neqinisiweyo, intsimbi yolwakhiwo → HRC / HB
Ubulukhuni obuphezulu: iidayi ezicinyiweyo, izixhobo, iibheringi → HRC / HV
Iileya zomphezulu ezibhityileyo kakhulu / iileya ezine-carburised → HV Vickers
