Umhlahlandlela Wesinyathelo Esisodwa Wokukhetha Uhlobo Olufanele
Khetha ngokusekelwe kubukhulu obuhlanu: usayizi womsebenzi, izinto zokwakha, ububanzi bobulukhuni, izidingo zokunemba, kanye nezimo zokusetshenziswa. Akunasidingo sokukhathazeka, vele ulandele umhlahlandlela bese ungenza isinqumo.
I. Okokuqala, hlukanisa izinhlobo ezintathu ezinkulu zabahloli bokuqina
1. I-Rockwell Hardness Tester (HRC/HRB/HRA)
Ifanele: insimbi ecinyiwe, insimbi edayiwe, amabheringi, amathuluzi, izingxenye eziphathwe ngokushisa
Izinzuzo: ukunemba okuphezulu, okusetshenziswa kabanzi ezindinganisweni zikazwelonke, imishini ejwayelekile yokuhlola ikhwalithi yefektri
Okubi: kumele uthathe amasampula / uhlobo lwedeskithophu, izingxenye ezinkulu azikwazi ukususwa noma ukuhlolwa endaweni
Okufanele ukulinganiswe:
I-HRC: insimbi eqinile eqinile (amadayi, amathuluzi, amagiya)
I-HRB: ithusi, i-aluminium, insimbi ephansi yekhabhoni, insimbi ethambile
2. Isivivinyo Sokuqina Kwe-Brinell (HB)
Ifanele: insimbi ephonswe, insimbi ephonswe, i-aluminium alloy, i-copper alloy, izingxenye ezibunjiwe ezingahlelekile
Izinzuzo: ukugoba okukhulu, okunembe kakhulu ezintweni eziqinile nezingafani
Okubi: ukugoba okukhulu, ukubhubhisa, ukusebenza kahle okuphansi, okufanele ukuhlolwa kwezindawo zelebhu
3. Isivivinyo Sokuqina Kwe-Leeb (i-HL ephathekayo ibe yi-HRC/HB/HV)—Isivivinyo Sokuqina Kwe-Leeb se-YY251D
Ifanele: izingxenye ezinkulu, ukuhlolwa endaweni, izingxenye ezingenakuhlukaniswa, isikhunta esinzima, imiqulu, imigoqo
Izinzuzo: iphathwa ngesandla futhi iyaphatheka, ayibhubhisi, asikho isidingo sokuthatha amasampula, ingasetshenziswa ezindaweni eziqondile, ezivundlile, noma ezingenhla
Okubi: ukunemba okuphansi kancane kune-desktop Rockwell, amaphutha amakhulu ezingxenyeni ezincane nezinodonga oluncane
II. Khetha ngokusekelwe ezimweni zohlelo lokusebenza (ezisebenziseka kakhulu)
Isimo 1: ilabhorethri yokusebenzela, ukuhlolwa kwekhwalithi yezinto ezingenayo / ukwelashwa kokushisa, ukunemba okuphezulu kuyadingeka Khetha isihloli sokuqina se-Rockwell sedeskithophu
Kukhethwa kakhulu ezimbonini zehadiwe ezijwayelekile, ezokwakha ngomshini wokushisa, kanye nezokulungisa ukushisa.
Isimo 2: insimbi ephothiwe, izinto eziphothiwe, i-aluminium alloy, izingxenye eziphothiweyo ezingahlelekile
Khetha isihloli sokuqina kweBrinell
Isimo 3: izingxenye ezinkulu ezingenakunyakaziswa, ukuhlolwa endaweni, isikhunta/ama-roll/imigoqo emikhulu Kumelwe ukhethe isihloli sokuqina se-Leeb esiphathwayo
Isimo 4: izingxenye ezincane, amashidi amancane, ubulukhuni bomphezulu wezendlalelo ezifakwe i-carburized kanye ne-nitride Khetha isihloli sobulukhuni be-Vickers (HV)
Ifanele: amashidi amancane, imiphetho yamathuluzi, izembozo, izendlalelo eziqinile.
III. Khetha ngokusekelwe ekujikeni/usayizi wezinto zokusebenza
Izingxenye ezinkulu, ezisindayo, nezingashukumi → Leeb
Amasampula ajwayelekile, izingxenye ezincane, angafakwa kudeskithophu → Rockwell
Izingxenye ezincane < 3mm, izendlalelo eziqinile ebusweni → Ama-Vickers
Izinto ezingenalutho ezifakwayo, izinto ezingezona ezifanayo → Brinell
IV. Khetha ngokusekelwe ezingeni lobulukhuni
Izinto ezithambile: i-aluminium, ithusi, insimbi ephansi yekhabhoni → HRB / HB
Ubulukhuni obuphakathi: insimbi ecinyiwe nethambile, insimbi yesakhiwo → HRC / HB
Ubulukhuni obuphezulu: amadayi acishiwe, amathuluzi, amabheringi → HRC / HV
Izendlalelo zobuso ezincane kakhulu / izendlalelo ezifakwe i-carburized → HV Vickers
