I-1. Ukucinywa kunye nentsimbi evuthiweyo
Uvavanyo lobunzima lwelitye elicinyiwe kwaye luvuthiwe intsimbi ikakhulu isebenzisa i-rockwell hards test hrc. Ukuba umxholo ucekeceke kwaye i-HRC Sum ayifanelekanga, isikali se-HRA sinokusetyenziswa endaweni yoko. Ukuba umxholo ucekeceke, umphezulu we-rockwell scales hr15n, hr30n, okanye hr45n inokusetyenziswa.
2. Umphezulu wensimbi yentsimbi
Kwimveliso yemizi-mveliso, ngamanye amaxesha eyona nto iphambili ekufuneka yenziwe ukuba ibe nzima, ngelixa umphezulu nokunyanzeleka ukuba ube nobunzima obukhulu kwaye unxibe ukunganyangeki. Kule meko, ukucinywa rhoqo ngokungxama, ukuqunjelwa komzimba okuphezulu, i-calburing, i-carbonirhating, i-carbonitering kunye nezinye iinkqubo zisetyenziselwa ukwenza izinto ezikhulayo kumsebenzi. Ubungqingqwa bomaleko obolekayo buhlala buhlala phakathi kweemilimitha ezimbalwa kunye neemilimitha ezimbalwa. Ngezixhobo ezinemigangatho yokuqina komgangatho, izikali ze-HRC zinokusetyenziselwa ukuvavanya ubunzima babo. Kwisiphelo sendawo yokuqina komgangatho, i-HRD okanye isikali se-HRD singasetyenziswa. Ngeengqengqelo zomhlaba ezinqabileyo, umphezulu we-rockwell scales hr15n, hr30n, kunye hr45n kufuneka zisetyenziswe. Kwimigangatho ye-titner ters, i-vyskers encinci i-titer okanye imvano-moya eqinileyo ye-Ultrasonic kufuneka isetyenziswe.
I-3. Intsimbi yentsimbi, intsimbi eqhelekileyo, intsimbi ethobekileyo
Izinto ezininzi zensimbi ziveliswa kwimeko yeNened okanye eqhelekileyo, kwaye ezinye zeepleyiti ezibandayo eziqengqelekayo nazo zikhutshwa ngokweziganga ezahlukeneyo zokungena. Ukuvavanywa kobunzima beento ezahlukeneyo ezivaliweyo zihlala zisebenzisa isikali se-HRB, kwaye ngamanye amaxesha isikali se-HRF sisetyenziselwa iipleyiti ezithambileyo nezincinci. Ngeepleyiti ezicekeceke, i-rockwell i-robters testers hr15t, HR30T, kunye ne-HR45T Scales kufuneka zisetyenziswe.
4. Intsimbi engenasibala
Izixhobo zentsimbi ezingenazilutho zihlala zinikezelwa kumazwe anje ngokwenza oko, ngokucofa, ukuwamisela, kunye nesisombululo esomeleleyo. Imigangatho yeSizwe ichaza amaxabiso aphezulu aphezulu kwaye asezantsi, kunye nokuvavanywa kobunzima kuhlala kusebenzisa i-robwell test roty hrc okanye isikali se-HRB. Isikali se-HRB siya kusetyenziselwa intsimbi engekhoyo kunye nentsimbi engenasiseko, isikali se-HRC sobunzima be-robwell siya kusetyenziselwa i-tubes ye-Marten kunye ne-HRNGORY STERNORY STERNORY STESTARY STERNAYS EYENZIWEYO I-1 ~ 2mm.
5. Intsimbi
Uvavanyo lobunzima beBrinell ubunzima luhlala lusetyenziselwa intsimbi, kuba i-microst yolawulo yensimbi ayifani, kwaye uvavanyo lwe-brinell vaction lukhulu. Ke ngoko, uvavanyo lukhuni lweBrinell lunokubonakalisa iziphumo ezibanzi zoLwaphulo-mthetho kunye neeProteti zazo zonke iindawo zezinto ezibonakalayo.
I-6. I-iron yentsimbi
Izinto zentsimbi zentsimbi zihlala zibonakaliswa ngendlela engalinganiyo kunye neengqolowa ezinamabala, ke kuvavanyo lobunzima bukhali. I-rockwell ubunzima bobunzima bunokusetyenziselwa uvavanyo olunzima lwabathile bentsimbi. Apho kungekho ndawo yaneleyo kwinkonzo encinci yengqolowa yokuphosa uvavanyo lobunzima beBrinell, i-HRB okanye i-HRB okanye i-HRB Scales, enokufumana iibhola ze-3.588mm.
Izinto ezinqabileyo zentsimbi ezinobunzima zihlala zisebenzisa i-rockwell hardtrance hrc. Ukuba umxholo awulingani, idatha emininzi inokulinganiswa kwaye ixabiso elithathiweyo elithathiweyo.
I-7. I-carbide ye-carbide ye-Fardy)
Ukuvavanywa kobunzima bezixhobo ze-alloy ezinzima zihlala zisebenzisa kuphela i-rockwell hardtrance horance hra.
