1. Insimbi ecisiwe futhi evuswe
Ukuhlolwa kobulukhuni kwensimbi ecijile nenomsindo ikakhulukazi isebenzisa i-Rocwell Hardness Aster HRC isikali. Uma okuqukethwe kunciphile futhi isikali se-HRC asifanelekile, i-HRA SCALE ingasetshenziswa esikhundleni salokho. Uma okuqukethwe kuncipha, i-Surface Hardness Hardness Scales HR15N, HR30N, noma i-HR45N ingasetshenziswa.
2. Insimbi eqinile
Ekukhiqizeni kwezimboni, kwesinye isikhathi umnyombo wesisebenzi sokusebenza kudingeka ukuba ube nobunzima obuhle, kanti ingaphezulu liyadingeka ukuthi lube nobulukhuni obuphezulu nokugqoka ukumelana. Kulokhu, imvamisa ephezulu yokuqothula, ukuqeqeshwa kwamakhemikhali, i-nitriding, i-carbonitriding nezinye izinqubo zisetshenziselwa ukwenza ukwelashwa okuqinisayo komhlaba ku-workpiepe. Ubukhulu besendlalelo eqinile se-surting ngokuvamile phakathi kwamamilimitha ambalwa kanye namamilimitha ambalwa. Ngezinto zokwakha ezinezingqimba ezinzima zangaphandle, izikali ze-HRC zingasetshenziswa ukuvivinya ubulukhuni bawo. Ukuqina okuphakathi kwensimbi eqinile, izikali ze-HRD noma ze-HRA zingasetshenziswa. Ngezendlalelo ezinzima ezingaphezulu komhlaba, izikali ze-surf rocwell hardness izikali HR15N, HR30N, futhi i-HR45N kufanele isetshenziswe. Ngezendlalelo eziqinile eziqinile, umhloli we-hardness we-hickers amancane noma umhloli we-hardness we-ultrasonic kufanele asetshenziswe.
I-3. Insimbi Enensimbi Engenayo, Insimbi Ejwayelekile, Insimbi Emnene
Izinto eziningi zensimbi zikhiqizwa ngesimo esiveziwe noma esijwayelekile, futhi amanye amapuleti ensimbi ebandayo nawo ahlanganiswe ngokuya ngama-degree ahlukahlukene anveling. Ukuhlolwa kobulukhuni kwensimbi ehlukahlukene evenule kuvame ukusebenzisa izikali ze-HRB, futhi kwesinye isikhathi izikali ze-HRF nazo zisetshenziselwa amapuleti athambile namancanyana. Ngamapuleti ancanyana, ama-rockwell hardness testers HR15T, i-HR30T, kanye nesikali se-HR45T kufanele kusetshenziswe.
4. Insimbi Engagqwali
Izinto zensimbi engagqwali zivame ukuhlinzekwa ezifundeni ezinjenge-anveling, ukucimasha, ukufutheka kanye nesixazululo esiqinile. Amazinga Kazwelonke acacisa amanani ahambelana ahambisanayo aphezulu nangaphansi, futhi ukuhlolwa kanzima kuvame ukusebenzisa i-Rocwell Harveness Viser HRC noma izikali ze-HRB. Isikali se-HRB sizosetshenziselwa insimbi engenacala ye-auntenitic ne-Ferrititic, kuzosetshenziselwa i-HRC yesilinganiso se-Artensite ye-Martensite kanye ne-HRN noma i-HRT Scale ye-RocKwell Harden Tests izosetshenziselwa amashubhu angaphansi kwe-1 ~ 2mm.
I-5. Insimbi ekhethiwe
I-Brinell Hardness Hardness Test Test ivame ukusetshenziselwa insimbi eyenziwe, ngoba i-micross.com yensimbi ayifani ngokwanele, futhi i-brinell Harvenness test iventation inkulu. Ngakho-ke, ukuhlolwa kwe-Brinell Harveness kungakhombisa imiphumela ephelele ye-misfructure kanye nezakhiwo zazo zonke izingxenye zezinto ezibonakalayo.
6.
Izinto zensimbi ze-cast zivame ukuvezwa ngesakhiwo esingalingani kanye ne-coarse grain, ngakho-ke ukuvivinya ubunzima be-brinell kuvame ukwamukelwa. Umhloli wobulukhuni we-Rocwell angasetshenziselwa ukuhlolwa kobulukhuni bamanye ama-wetron weron. Lapho kungekho ndawo eyanele engxenyeni encane yokusanhlamvu okuhle okuphonsa ubunzima be-Brinell Hardenerness Hardness, kepha kungcono ukusebenzisa amabhola we-HRE noma i-HRK, ngoba i-HRE kanye ne-HRK Scases basebenzisa ukufundwa kwensimbi engcono ku-1.588mm.
Izinto zensimbi ezinamakhaza eziqinile zivame ukusebenzisa umhloli we-rockill hardness HRC. Uma okuqukethwe kungalingani, idatha eminingi ingalinganiswa futhi inani elijwayelekile elithathiwe.
7. I-Carbide (Hard Alloy)
Ukuhlolwa kobulukhuni kwezinto zokwakha ezilukhuni kuvame ukusebenzisa i-RocKwell Harveness Tenser Hra Scale.
